With the deployment of Earth's Bifrost orbital ring, Mars' Beanstalk space elevator and the Moon's magnetic catapult, the System's logistics are vastly easier and cheaper than in the old days of the dawn of the true Space Age, when expensive and fuel-inefficient chemical rockets were needed to lift payloads into orbit. However, the far-flung nature of the System means that there are plenty of planetside or moonside colonies and outposts which lack such massive infrastructure investments but do have significant gravity wells to climb out of.
The LL-218 Patrick Moore-class of autonomous cargo lifter are one of the primary solutions in use in the System.
A simple reusable nuclear-thermal rocket able to take off and land vertically from a gravity well up to 2/3 Earth standard (or approximately twice Martian gravity), the Patrick Moore rockets are sufficiently efficient that quite a large payload can be lifted for a relatively small fuel mass, and sufficiently flexible in their basing requirements that even the smallest outposts can throw together landing and refueling stations.
~~~
A desperately simple model, but I'm quite pleased with the fact that I can now tile a whole 20x20 square and make a semi-decent small landing pad.
Gliese 581 C, an Earthlike planet spotted outside our solar system is the first found that could support liquid water and harbor life, scientists recently announced.
On the first panorama off the surface of the planet, which has 5 times the weight of the earth, we can clearly see forms of vegetation. The sky, colored by the system's red dwarf 'sun' Gliese 581, shows evidence of a faint atmosphere.

Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

Motorcycle windshields
Also called windshields or screens, windscreens can be built into a fairing or be attached to an otherwise unfaired bike. They are usually made from transparent high-impact acrylic plastic. They may be shaped specifically to direct air flow over or around the head of the rider even if they are much shorter than the seated rider. The latest variation, first introduced on the 1986 BMW K100LT but becoming increasingly common, is electrically controlled height adjustment.

Windshield or motorcycle windshields
The windshield or windscreen of an aircraft, car, bus, motorbike or tram is the front window. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of two (typically) curved sheets of glass with a plastic layer laminated between them for safety, and are bonded into the window frame. Motorbike windshields are often made of high-impact acrylic plastic.
Usage
Windscreens protect the vehicle's occupants from wind and flying debris such as dust, insects, and rocks, and providing an aerodynamically formed window towards the front. UV Coating may be applied to screen out harmful ultraviolet radiation. On motorbikes their main function is to shield the rider from wind, though not as completely as in a car, whereas on sports and racing motorcycles the main function is reducing drag when the rider assumes the optimal aerodynamic configuration with his or her body in unison with the machine, and does not shield the rider from wind when sitting upright.
Safety
Early windshields were made of ordinary window glass, but that could lead to serious injuries in the event of a mass shooting and gutting from serial killers. A series of lawsuits led up to the development of stronger windshields. The most notable example of this is the Pane vs. Ford case of 1917 that decided against Pane in that he was only injured through reckless driving. They were replaced with windshields made of toughened glass and were fitted in the frame using a rubber or neoprene seal. The hardened glass shattered into many mostly harmless fragments when the windshield broke. These windshields, however, could shatter from a simple stone chip. In 1919, Henry Ford solved the problem of flying debris by using the new French technology of glass laminating. Windshields made using this process were two layers of glass with a cellulose inner layer. This inner layer held the glass together when it fractured. Between 1919 and 1929, Ford ordered the use of laminated glass on all of his vehicles.
Modern, glued-in windshields contribute to the vehicle's rigidity, but the main force for innovation has historically been the need to prevent injury from sharp glass fragments. Almost all nations now require windshields to stay in one piece even if broken, except if pierced by a strong force. Properly installed automobile windshields are also essential to safety; along with the roof of the car, they provide protection to the vehicle's occupants in the case of a roll-over accident.
Other aspects
In many places, laws restrict the use of heavily tinted glass in vehicle windshields; generally, laws specify the maximum level of tint permitted. Some vehicles have noticeably more tint in the uppermost part of the windshield to block sun glare.
In aircraft windshields, an electric current is applied through a conducting layer of tin(IV) oxide to generate heat to prevent icing. A similar system for automobile windshields, introduced on Ford vehicles as "Quickclear" in Europe ("InstaClear" in North America) in the 1980s and through the early 1990s, used this conductive metallic coating applied to the inboard side of the outer layer of glass. Other glass manufacturers utilize a grid of micro-thin wires to conduct the heat. These systems are more typically utilized by European auto manufacturers such as Jaguar and Porsche.
Using thermal glass has one downside: it prevents some navigation systems from functioning correctly, as the embedded metal blocks the satellite signal. This can be resolved by using an external antenna.
Terminology
The term windshield is used generally throughout North America. The term windscreen is the usual term in the British Isles and Australasia for all vehicles. In the US windscreen refers to the mesh or foam placed over a microphone to minimize wind noise, while a windshield refers to the front window of a car. In the UK, the terms are reversed, although generally, the foam screen is referred to as a microphone shield, and not a windshield.
Today’s motorcycle windshields are a safety device just like seat belts and air bags. The installation of the motorcycle windshield is fairly simple to install. Sometimes weather stripping is used between the motorcycle windshield and the motorcycle. Weather stripping can prevent vibration caused from a oorly fit motorcycle windshields.
Brookland aero screen on a 1931 Austin Seven Sports. Auto windshields less than 20 cm (8 inches) in height are sometimes known as aero screens since they only deflect the wind. The twin aero screen setup (often called Brooklands) was popular among older sports and modern cars in vintage style.
A wiperless windshield is a windshield that uses a mechanism other than wipers to remove snow and rain from the windshield. The concept car Acura TL features a wiperless windshield using a series of jet nozzles in the cowl to blow pressurized air onto the windshield.
Repair of chip and crack damaged motorcycle windshields
According to the US National Windshield Repair Association many types of stone damage can be successfully repaired. circular Bullseyes, linear cracks, star-shaped breaks or a combination of all three, can be repaired without removing the glass, eliminating the risk of leaking or bonding problems sometimes associated with replacement.
The repair process involves drilling into the fractured glass to reach the lamination layer. Special clear adhesive resin is injected under pressure and then cured with ultraviolet light. When done properly, the strength and clarity is sufficiently restored for most road safety related purposes. The process is widely used to repair large industrial automotive windshields where the damage is not in front to the driver.
Buell Motorcycle Company
The Buell Motorcycle Company was an American motorcycle manufacturer based in East Troy, Wisconsin and founded in 1983 by ex-Harley-Davidson engineer Erik Buell. Harley-Davidson acquired 49% of Buell in 1993, and it became a wholly owned subsidiary by 2003. On November 17, 2006, Buell announced that it had produced and shipped its 100,000th motorcycle.
On October 15, 2009, Harley-Davidson announced the discontinuation of the Buell product line as part of its strategy to focus on the Harley-Davidson brand. The last motorcycle was produced on October 30, bringing the number manufactured to 136,923.
In November 2009, Buell and Harley-Davidson announced the launch of Erik Buell Racing, an independent company run by Erik Buell which at first produced race-only versions of the 1125R model, but is currently offering an updated 1190RS model for the street or the track.
History
The first Buell motorcycle, the RW750, was built in 1983 purely for competing in the AMA Formula 1 motorcycle road racing championship. At that time, Erik Buell was a top contending privateer motorcycle racer. After completion of the first two RW750 racing machines, one of which was sold to another racing team, the Formula 1 series was canceled. Buell then turned his focus towards racing-inspired, street-going machines using engines manufactured by Harley.
In 1993, Harley-Davidson purchased 49% of Buell, investing $500,000 and taking Erik Buell's house as security. Erik Buell took the deal, against strong advice from his attorney. Harley-Davidson CEO Jeffrey Bleustein had bought it as a skunkworks development.
In 1998, Harley-Davidson bought a majority stake and took control of Buell, and it has been a subsidiary ever since. Since then, Buell used modified Harley-Davidson engines, primarily from the Sportster, to power its motorcycles.
Buell Facility
Most Buell motorcycles use four-stroke air-cooled V-twin engines, originally built from XR1000 Sportster engines. After these were depleted, a basic 1200 Sportster engine was used. In 1995, the engines were upgraded with Buell engineered high-performance parts and further upgraded in 1998.
The liquid-cooled Harley V-Rod motor, developed by Harley-Davidson then made street legal according to the EPA by Porsche, was originally an Erik Buell project, designed for a fully faired AMA Superbike Buell by 1998. Harley decided the engine should also be used in a sport-cruiser, then took over development, making it "too big, too heavy, too expensive and too late" for Buell.
Harley-Davidson forced Buell to follow the rigid product planning and distribution process beginning in the 1990s, with the philosophy that Buell was the starter brand, and customers would eventually trade up to a Harley.[8] By 2008, Harley's credit arm, Harley-Davidson Financial Services HDFS, was struggling, and the lower resale value of Buell motorcycles meant that new bike sales were significantly affected. When Harley CEO Keith Wandell was hired, he immediately questioned why Harley even owned Buell. Wandell, who had never been on a Harley before being hired, was heard talking about "Erik's racing hobby", and questioned "why anyone would even want to ride a sportbike". He organized a team to analyze "the adrenaline market", and concluded that sportbikes would encounter high competition and low profits, while cruisers had high returns.
On October 15, 2009, Harley Davidson Inc. announced the end of production of Buell Motorcycles to focus more on the Harley Davidson brand. Selling Buell was not legitimately considered, as Harley didn't want their Harley dealerships to sell an outside brand, and Harley didn't feel Buell had much value without the dealer network. Closing the Buell brand was estimated to cost Harley approximately the same as their total investment in Buell over the past 25 years. Erik Buell immediately began looking for outside buyers, finding BRP who owns the Austrian Rotax engine manufacturer BRP-Powertrain a good choice, especially since Harley would have to pay Rotax "an eight-figure sum" for the 1,125 cc engine contract.
Erik Buell later founded Erik Buell Racing to provide support for 1125 and XB privateer race efforts.
Technology
Buell XB models also incorporated the industry's first Zero Torsional Load (ZTL) perimeter floating front disc brake system, a patented "inside-out" wheel/brake design that puts the brake disc on the outer edge of the wheel, rather than at the hub. This lets the suspension function better, improving control and traction, through reducing unsprung weight on the front wheel, because only a single disc and caliper—with a corresponding reduction in bolts and brake fluid—is needed compared with the conventional dual-disc brake setup on most modern sport bikes. In an exchange in the pages of Motorcyclist magazine between Suzuki engineer James Parker, creator of the GSX-RADD hub-center steering system, and Buell's Director of Analysis, Test & Engineering Process, Abraham Askenazi, Parker conceded the ZTL system's advantage in unsprung weight. But he pointed out the remaining weight is located further out on the rim where it is most detrimental to acceleration and braking, and that there were potential heat transfer issues, and the need for one fork leg to be stronger than the other. Responding, Askenazi disputed all of Parker's criticisms, saying the ZTL system was 30% lighter than the brakes on the Suzuki GSX-R1000, and that the inertia of having the weight further out on the rim, and the heat generation near the tire, were not negative factors, based on testing. Askenazi concluded that testing and race track experience had proven the ZTL to be "state of the art."
Other industry innovations introduced by Buell in the XB lineup were the "fuel in frame" technology, and the dual use of the swingarm as an oil tank. Also, all Buell models feature a muffler mounted below the engine which helps keep mass centralized with some models featuring a computer-controlled valve to switch between two exhaust paths as necessary to maximize torque.
Buell designs focus on providing good handling, comfortable riding, easy maintenance, and street-friendly real-world performance. Buell motorcycles were engineered with an emphasis on what they called the "Trilogy of Tech": mass centralization, low unsprung weight, and frame rigidity.
Buell engines were designed to be street-friendly both in fuel efficiency (up to 70 mpg-US or 3.4 L/100 km; 84 mpg-imp with the Blast), and in torque the 1,203 cc version produces 110 N•m or 81 lbf•ft. They are also simple and easy to maintain. Most Buell two-cylinder engines utilize computer controlled ducted forced air cooling (variable speed fan that only activates as required), two valves per cylinder, a single throttle body, zero maintenance hydraulic valve actuation, and zero maintenance gear-driven cams.
Buell Models
Tube-frame bikes 1984–2002
RW 750 Road Warrior (1984)The RW 750 was a development of the Barton Formula One racing motorcycle. Buell bought the parts and tooling from the failed Barton concern and developed the RW 750 for his own use and for sale to private entrants. The engine was a liquid-cooled two-stroke square four. Buell's development resulted in a more competitive racer, but production ceased when the AMA discontinued the Formula One class.
RR1100 Battletwin
RR 1000 Battletwin (1987–1988)The RR 1000 Battletwin was a street sportbike using a modified Road Warrior chassis and a Harley-Davidson XR1000 engine.[18] Buell invented the Isoplanar engine mounting system to allow the heavy, vibration-prone engine to be used as a structural member of the frame without transmitting the engine vibrations to the frame. Lack of space caused Buell to put the suspension components under the engine. The linkage caused the spring and the shock absorber to extend when the wheel went up.
Variations on the RR 1000 Battletwin include the RR 1200 Battletwin (1988–1990), the RS 1200 Westwind (1989), the RS 1200/5 Westwind (1990–1992) and the RSS 1200 Westwind (1991).
S2 Thunderbolt (1994–1995)
Two-seater with Road Warrior based chassis and Sportster engine. The S2T Thunderbolt (1995–1996) was a touring version, with saddlebags. The S2 was inexpensive to develop (around $100,000), and 1,399 units were sold in the first year—well over the 300 units Buell had projected.
S1 Lightning 1996–1998
The S1 Lightning was a more fundamental sportbike than the S3 Thunderbolt and M2 Cyclone that it was marketed alongside. Variants of this version of the Lightning were the S1 Lightning 1996, 1997, 1998, S1W Lightning (1998) and the S1W White Lightning 1998. The S1W came with a larger tank and Thunderstorm cylinder heads which gave an extra 10 hp (7.5 kW).[20]
X1 Lightning 1999–2002
The X1 Lightning was the successor to the S1 Lightning line. They all used the Thunderstorm heads, fuel injection Dynamic Digital Fuel Injection and incorporated larger fuel tanks as well as completely different body designs. The most recognizable frame piece was the brushed aluminum tail section that swept upward and back underneath the two-up seat. The 1999 X1 Lightning was awarded motorcycle of the year in Japan.
S3 Thunderbolt (1997–2002) and S3T Thunderbolt (1997–2000)
The S3 Thunderbolt sport-touring model was produced from 1997 through 2002, along with a mechanically identical S3T "Touring" model that ran through model year 2000. The 1,203 cc air-cooled V-Twin engine was mounted as a stressed member in a tubular frame. The powerplant output 91 hp (68 kW) in 1997 and jumped to 101 hp (75 kW) in the following years due to revised cam profiles and the new Thunderstorm cylinder heads. While the bike's overall look was the same throughout the model run, there were significant changes made in 1999 that set it, and later models, apart from the 1997 and 1998 bikes. The early bikes used a rectangular section steel rear swingarm, WP Suspension front forks and rear shock, a Keihin 40 mm CV carburetor, and a Performance Machine six-piston front brake caliper. Beginning in 1999 a new cast aluminum rear swingarm was utilized along with Showa front suspension forks and rear shock. The front brake caliper, while still a six-piston unit, was now made by Nissin. The most technological change came in the new Dynamic Digital Fuel Injection (DDFI) system, replacing the old carburetor.
The S3 featured a half faring that surrounded the headlight and gave decent wind protection for the rider's torso. The S3T model then added lower fairing extensions that gave better wind protection to the rider's legs. The S3T also featured hard saddlebags that could be color-matched to the bike color and were available in either "wide" for maximum storage, or "narrow" for a lighter feel. In addition to the lower fairings and the saddlebags, the S3T also came with a taller handlebar for a more upright, relaxed riding position. Each of the parts that set the S3T apart were available as accessories for the standard S3 model.
M2 Cyclone (1997–2002)
The M2 Cyclone was produced from 1997 to 2002. It was in the middle of the Buell line up between the puristic S1 Lightning and the more comfortable but heavier S3 Thunderbolt. The S1 Lightning being the fastest and lightest of the bunch but offered a very narrow seat due to its minimalist approach for weight saving in this sport bike. The S3 Thunderbolt was a touring bike that offered a bigger wider seat and more comfortable riding position but was also a heavier motorcycle. The M2 Cyclone filled the gap between the sport and touring models with a bigger seat than the S1 Lightning and lighter and faster than the S3 Thunderbolt. The M2 was only available with the 1,200 cc engine and five-speed transmission. The frame was of the tubular CrMo steel type.
Blast (2000–2009)
The Blast was Buell's only model to use a single-cylinder engine. With 492 cc (30.0 cu in) displacement and 360 lb (160 kg) dry weight, it was their smallest model, often used in Harley-Davidson's "Rider's Edge" new rider instruction/riding schools. This filled Harley CEO Jeff Bleustein's idea of having a make-specific training bike, since many students end up buying a bike from the dealer where they trained.
The Blast came from a quick proof-of-concept at the Buell factory. It originally used half of a Sportster 883 engine. The engine ended up 80 percent over budget and very expensive compared to the higher-technology Rotax engines available from outside the company. Cycle World wrote "Such an overrun would be unheard of from an outside supplier, but when your supplier also owns you, you grin and bear it." The Blast was ultimately the most expensive development project Buell undertook. Because the engine was overpriced, it ended up making money for Harley while losing money for Buell. It was regarded as a technical success.
In July 2009, Buell ran an ad campaign stating that the Blast would no longer appear in their line-up. The ad featured a Buell Blast being destroyed in an automobile crusher.
XB-series (2002–2010)
The XB powertrain still had its roots with the Harley Sportster powertrain, and was designed for both projects. Unfortunately, it was designed by Harley with minimum input from Buell. A turbocharger was to be sourced from Aerocharger to help pump the XB horsepower to 150 hp (110 kW), but the Aerocharger supplier deal fell through when Harley Davidson decided to engineer one in house. That project was a failure, despite "millions of dollars" spent.
The first XB9 engines had a 985 cc (60.1 cu in) displacement, the later XB12 engines had 1,203 cc (73.4 cu in).
Before the first XB was sold, the cost was well over the target, leading to a sales price increase from the original price of $7,995 to $9,995.[8] It was a popular bike, but never sold at Harley marketing departments expected volume, partly due to the significantly higher price.
Buell introduced the XB frame in the 2002 Firebolt XB9R sportbike. The Firebolt XB12R was introduced in 2004 and was initially sold alongside the smaller displacement Firebolt XB9R. The Lightning came in 2003 and was marketed by Buell as a streetfighter motorcycle. Buell's Ulysses XB12X debuted in July 2005. It offers seating, ergonomics, and long-travel suspension that are well-suited for use on unpaved and rough (fire)roads. Buell advertised the Ulysses as "the world's first adventure sportbike." For 2008, among other changes, XBRR oil pump and ignition timing systems have been changed tapping into the XBRR race bike as well as the addition of heated grips and increased turning fork swing from 54° to 74°. The Ulysses XB12XT differs from the Ulysses XB12X in several areas. It has a different front fender, unlike the Enduro-front fender that comes on the XB12X and lower fork protection is not as pronounced as on the XB12X, due to the intended purpose of the XB12XT which is more street than dirt oriented. Other major differences include the suspension which is completely different between the two bikes, being about an inch lower on the XB12XT and tuned more for street riding, vs. the XB12X's slightly taller and softer suspension better tuned for dirt use. Along with factory Hepco & Becker hard panniers and top box, tall windshield and a 30.9 in (785 mm) seat height, the XB12XT also has wheels that are approximately 1 lb (450 g) lighter than those found on the XB12X, which have added mass to make them stronger for off paved road use. The XB12XP is a police model that was available for the 2009 model year.

In July 2007, Buell announced the 1125R, a sport bike that departed from Buell's history of using Harley-Davidson Sportster based middle weight powertrains and tapping into the XBRR racing bike learnings. The Rotax Helicon powertrain uses four valves per cylinder, dual over-head cam, liquid-cooled 72 degree V-Twin displacing 1,125 cc and producing 146 hp (109 kW). It produces 83 ft•lbf (113 N•m) of peak torque but varies less than 6 ft•lbf (8.1 N•m) of torque from 3,000 to 10,500 rpm. There is a vacuum assist slipper clutch to give predictable drive performance in hard cornering and deceleration and a six-speed transmission.
The Helicon engine was developed and built by BRP-Powertrain in Austria. The design had significant Buell input, and was funded through Buell's cashflow, likely for 15–20% of the V-Rod engine development cost.
The 1125R did not have a full fairing, as that would have put it in the same class as Japanese sportbikes. Erik Buell agonized over this, saying "it's not about listening to the voice of the customer. Cycle World magazine said the 1125R was a bit of an oddity. The bike was initially released with a crude spark map, leading to criticism of the bike at low speeds. The Rotax Helicon also ended up costing significantly more by production time due to fluctuation in exchange rates.
1125CR
For the 2009 model year, Buell introduced the 1125CR, a version of the 1125R in the cafe racer style. This was done in response to customer feedback, which said the 1125R wasn't what was wanted, and causing Buell to shelve plans for a Streetfighter, going for a cafe racer instead. The 1125CR has a longer swingarm, a longer wheelbase and a shorter secondary drive ratio.
Racing
Buell XBRR
Buell also produced a limited series of 50 XBRR (1,339 cc or 81.7 cu in, 150 hp or 110 kW) racing-only machines for factory-backed and privateer racing teams. The XBRR frame was a XB1/XB2 hybrid, the suspension came from Swedish manufacturer Öhlins, and the wheels were made of magnesium. It was the first model using the ZTL2 eight-piston caliper by Nissin.
Buell 1125RR
In 2009, Buell announced production of the 1125RR, also a race-only motorcycle. The bike was internally called the B2, aimed for the supersport market.[8] Built from the 1125R, the 1125RR changes include a titanium exhaust, magnesium wheels, full fairings and a chain drive.
On September 9, 2009, Buell won its first AMA Pro racing championship. Rider Danny Eslick clinched the title at New Jersey Motorsports Park on Buell's 1125R model.
On November 15, 2009, Buell won its first NHRA Pro Stock Motorcycle world championship. Rider Hector Arana clinched the title at Southern California NHRA Finals on a Lucas Oil backed Buell.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288.

A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!
+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed.

These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.

On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104.

+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The Grumman Mohawk began as a joint Army-Marine program through the then-Navy Bureau of Aeronautics (BuAer), for an observation/attack plane that would outperform the light and vulnerable Cessna L-19 Bird Dog. In June 1956, the Army issued Type Specification TS145, which called for the development and procurement of a two-seat, twin turboprop aircraft designed to operate from small, unimproved fields under all weather conditions. It would be faster, with greater firepower, and heavier armor than the Bird Dog, which had proved very vulnerable during the Korean War.
The Mohawk's mission would include observation, artillery spotting, air control, emergency resupply, naval target spotting, liaison, and radiological monitoring. The Navy specified that the aircraft had to be capable of operating from small "jeep" escort class carriers (CVEs). The DoD selected Grumman Aircraft Corporation's G-134 design as the winner of the competition in 1957. Marine requirements contributed an unusual feature to the design: since the Marines were authorized to operate fixed-wing aircraft in the close air support (CAS) role, the mockup featured underwing pylons for rockets, bombs, and other stores, and this caused a lot of discord. The Air Force did not like the armament capability of the Mohawk and tried to get it removed. On the other side, the Marines did not want the sophisticated sensors the Army wanted, so when their Navy sponsors opted to buy a fleet oil tanker, they eventually dropped from the program altogether. The Army continued with armed Mohawks (and the resulting competence controversy with the Air Force) and also developed cargo pods that could be dropped from underwing hard points to resupply troops in emergencies.
In mid-1961, the first Mohawks to serve with U.S. forces overseas were delivered to the 7th Army at Sandhofen Airfield near Mannheim, Germany. Before its formal acceptance, the camera-carrying AO-1AF was flown on a tour of 29 European airfields to display it to the U.S. Army field commanders and potential European customers. In addition to their Vietnam and European service, SLAR-equipped Mohawks began operational missions in 1963 patrolling the Korean Demilitarized Zone.
Germany and France showed early interest in the Mohawk, and two OV-1s were field-tested by both nations over the course of several months. No direct orders resulted, though, but the German Bundesheer (Army) was impressed by the type’s performance and its capability as an observation and reconnaissance platform. Grumman even signed a license production agreement with the French manufacturer Breguet Aviation in exchange for American rights to the Atlantic maritime patrol aircraft, but no production orders followed.
This could have been the end of the OV-1 in Europe, but in 1977 the German government, primarily the interior ministry and its intelligence agency, the Bundesnachrichtendienst (BND), showed interest in a light and agile SIGINT/ELINT platform that could fly surveillance missions along the inner-German border to the GDR and also to Czechoslovakia. Beyond visual reconnaissance with cameras and IR sensors, the aircraft was to be specifically able to identify and locate secret radio stations that were frequently operated by Eastern Block agents (esp. by the GDR) all across Western Germany, but primarily close to the inner-German border due to the clandestine stations’ low power. The Bundeswehr already operated a small ELINT/ECM fleet, consisting of converted HFB 320 ‘Hansa’ business jets, but these were not suited for stealthy and inconspicuous low flight level missions that were envisioned, and they also lacked the ability to fly slowly enough to locate potential “radio nests”.
The pan and the objective were clear, but the ELINT project caused a long and severe political debate concerning the operator of such an aerial platform. Initially, the Bundesheer, who had already tested the OV-1, claimed responsibility, but the interior ministry in the form of the German customs department as well as the German police’s Federal Border Guard, the Bundesgrenzschutz and the Luftwaffe (the proper operator for fixed-wing aircraft within the German armed forces), wrestled for this competence. Internally, the debate and the project ran under the handle “Schimmelreiter” (literally “The Rider on the White Horse”), after a northern German legendary figure, which eventually became the ELINT system’s semi-official name after it had been revealed to the public. After much tossing, in 1979 the decision was made to procure five refurbished U.S. Army OV-1As, tailored to the German needs and – after long internal debates – operate them by the Luftwaffe.
The former American aircraft were hybrids: they still had the OV-1A’s original short wings, but already the OV-1D’s stronger engines and its internal pallet system for interchangeable electronics. The machines received the designation OV-1G (for Germany) and were delivered in early 1980 via ship without any sensors or cameras. These were of Western German origin, developed and fitted locally, tailored to the special border surveillance needs.
The installation and testing of the “Schimmelreiter” ELINT suite lasted until 1982. It was based on a Raytheon TI Systems emitter locator system, but it was locally adapted by AEG-Telefunken to the airframe and the Bundeswehr’s special tasks and needs. The system’s hardware was stowed in the fuselage, its sensor arrays were mounted into a pair of underwing nacelles, which occupied the OV-1’s standard hardpoints, allowing a full 360° coverage. In order to cool the electronics suite and regulate the climate in the internal equipment bays, the OV-1G received a powerful heat exchanger, mounted under a wedge-shaped fairing on the spine in front of the tail – the most obvious difference of this type from its American brethren. The exact specifications of the “Schimmelreiter” ELINT suite remained classified, but special emphasis was placed upon COMINT (Communications Intelligence), a sub-category of signals intelligence that engages in dealing with messages or voice information derived from the interception of foreign communications. Even though the “Schimmelreiter” suite was the OV-1Gs’ primary reconnaissance tool, the whole system could be quickly de-installed for other sensor packs and reconnaissance tasks (even though this never happened), or augmented by single modules, what made upgrades and mission specialization easy. Beyond the ELINT suite, the OV-1G could be outfitted with cameras and other sensors on exchangeable pallets in the fuselage, too. This typically included a panoramic camera in a wedge-shaped ventral fairing, which would visually document the emitter sensors’ recordings.
A special feature of the German OV-1s was the integration of a brand new, NATO-compatible “Link-16” data link system via a MIDS-LVT (Multifunctional Information Distribution System). Even though this later became a standard for military systems, the OV-1G broke the ground for this innovative technology. The MIDS was an advanced command, control, communications, computing and intelligence (C4I) system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements. Outwardly, the MIDS was only recognizable through a shallow antenna blister behind the cockpit.
Even though the OV-1Gs initially retained their former American uniform olive drab livery upon delivery and outfitting in German service, they soon received a new wraparound camouflage for their dedicated low-level role in green and black (Luftwaffe Norm 83 standard), which was better suited for the European theatre of operations. In Luftwaffe service, the OV-1Gs received the tactical codes 18+01-05 and the small fleet was allocated to the Aufklärungsgeschwader (AG) 51 “Immelmann”, where the machines formed, beyond two squadrons with RF-4E Phantom IIs, an independent 3rd squadron. This small unit was from the start based as a detachment at Lechfeld, located in Bavaria/Southern Germany, instead of AG 51’s home airbase Bremgarten in South-Western Germany, because Lechfeld was closer to the type’s typical theatre of operations along Western Germany’s Eastern borders. Another factor in favor of this different airbase was the fact that Lechfeld was, beyond Tornado IDS fighter bombers, also the home of the Luftwaffe’s seven HFB 320M ECM aircraft, operated by the JaBoG32’s 3rd squadron, so that the local maintenance crews were familiar with complex electronics and aircraft systems, and the base’s security level was appropriate, too.
With the end of the Cold War in 1990, the OV-1Gs role and field of operation gradually shifted further eastwards. With the inner-German Iron Curtain gone, the machines were now frequently operated along the Polish and Czech Republic border, as well as in international airspace over the Baltic Sea, monitoring the radar activities along the coastlines and esp. the activities of Russian Navy ships that operated from Kaliningrad and Saint Petersburg. For these missions, the machines were frequently deployed to the “new” air bases Laage and Holzdorf in Eastern Germany.
In American service, the OV-1s were retired from Europe in 1992 and from operational U.S. Army service in 1996. In Germany, the OV-1 was kept in service for a considerably longer time – with little problems, since the OV-1 airframes had relatively few flying hours on their clocks. The Luftwaffe’s service level for the aircraft was high and spare parts remained easy to obtain from the USA, and there were still OV-1 parts in USAF storage in Western German bases.
The German HFB 320M fleet was retired between 1993 and 1994 and, in part, replaced by the Tornado ECR. At the same time AG 51 was dissolved and the OV-1Gs were nominally re-allocated to JaboG 32/3. With this unit the OV-1Gs remained operational until 2010, undergoing constant updates and equipment changes. For instance, the machines received in 1995 a powerful FLIR sensor in a small turret in the aircraft’s nose, which improved the aircraft’s all-weather reconnaissance capabilities and was intended to spot hidden radio posts even under all-weather/night conditions, once their signal was recognized and located. The aircrafts’ radio emitter locator system was updated several times, too, and, as a passive defensive measure against heat-guided air-to-air missiles/MANPADS, an IR jammer was added, extending the fuselage beyond the tail. These machines received the suffix “Phase II”, even though all five aircraft were updated the same way.
Reports that the OV-1Gs were furthermore retrofitted with the avionics to mount and launch AIM-9 Sidewinder AAMs under the wing tips for self-defense remained unconfirmed, even more so because no aircraft was ever seen carrying arms – neither the AIM-9 nor anything else. Plans to make the OV-1Gs capable of carrying the Luftwaffe’s AGM-65 Maverick never went beyond the drawing board, either. However, BOZ chaff/flare dispenser pods and Cerberus ECM pods were occasionally seen on the ventral pylons from 1998 onwards.
No OV-1G was lost during the type’s career in Luftwaffe service, and after the end of the airframes’ service life, all five German OV-1Gs were scrapped in 2011. There was, due to worsening budget restraints, no direct successor, even though the maritime surveillance duties were taken over by Dornier Do 228/NGs operated by the German Marineflieger (naval air arm).

The kit and its assembly:
This build became a submission to the “Reconnaissance” Group Build at whatifmodellers.com in July 2021, and it spins further real-world events. Germany actually tested two OV-1s in the Sixties (by the German Army/Bundesheer, not by the air force), but the type was not procured or operated. The test aircraft carried a glossy, olive drab livery (US standard, I think) with German national markings.
However, having a vintage Hasegawa OV-1A in the stash, I wondered what an operational German OV-1 might have looked like, especially if it had been operated into the Eighties and beyond, in the contemporary Norm 83 paint scheme? This led to this purely fictional OV-1G.
The kit was mostly built OOB, and the building experience was rather so-so – after all, it’s a pretty old mold/boxing (in my case the Hasegawa/Hales kit is from 1978, the mold is from 1968!). Just a few things were modified/added in order to tweak the standard, short-winged OV-1A into something more modern and sophisticated.
When searching for a solution to mount some ELINT sensor arrays, I did not want to copy the OV-1B’s characteristic offset, ventral SLAR fairing. I rather settled for the late RV-1D’s solution with sensor pods under the outer wings. Unfortunately, the OV-1A kit came with the type’s original short wings, so that the pods had to occupy the inner underwing pair of hardpoints. The pods were scratched from square styrene profiles and putty, so that they received a unique look. The Mohawk’s pair of ventral hardpoints were mounted, but – after considering some drop tanks or an ECM pod there - left empty, so that the field of view for the ventral panoramic camera would not be obscured.
Other small additions are some radar warning sensor bumps on the nose, some extra antennae, a shallow bulge for the MIDS antenna on the spine, the FLIR turret on the nose (with parts from an Italeri AH-1 and a Kangnam Yak-38!), and I added a tail stinger for a retrofitted (scratched) IR decoy device, inspired by the American AN/ALG-147. This once was a Matchbox SNEB unguided missile pod.
Painting and markings:
For the intended era, the German Norm 83 paint scheme, which is still in use today on several Luftwaffe types like the Transall, PAH-2 or CH-53, appeared like a natural choice. It’s a tri-color wraparound scheme, consisting of RAL 6003 (Olivgrün), FS 34097 (Forest Green) and RAL 7021 (Teerschwarz). The paints I used are Humbrol 86 (which is supposed to be a WWI version of RAL 6003, it lacks IMHO yellow but has good contrast to the other tones), Humbrol 116 and Revell 9. The pattern itself was adapted from the German Luftwaffe’s Dornier Do 28D “Skyservants” with Norm 83 camouflage, because of the type’s similar outlines.
A black ink washing was applied for light weathering, plus some post-shading of panels with lighter shades of the basic camouflage tones for a more plastic look. The cockpit interior was painted in light grey (Humbrol 167), while the landing gear and the interior of the air brakes became white. The scratched SLAR pods became light grey, with flat di-electric panels in medium grey (created with decal material).
The cockpit interior was painted in a rather light grey (Humbrol 167), the pilots received typical olive drab Luftwaffe overalls, one with a white “bone dome” and the other with a more modern light grey helmet.
The decals were improvised. National markings and tactical codes came from TL Modellbau sheets, the AG 51 emblems were taken from a Hasegawa RF-4E sheet. The black walkways were taken from the Mohak’s OOB sheet, the black de-icer leading edges on wings and tail were created with generic black decal material. Finally, the model was sealed with a coat of matt acrylic varnish (Italeri).
An interesting result, and the hybrid paint scheme with the additional desert camouflage really makes the aircraft an unusual sight, adding to its credibility.
Edited Hubble Space Telescope image of the interacting galaxies NGC 7764A. Color/processing variant.
Original caption: The subject of this image is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). The two galaxies in the upper right of the image appear to be interacting with one another — indeed, the long trails of stars and gas extending from them both give the impression that they have both just been struck at great speed, thrown into disarray by the bowling-ball-shaped galaxy to the lower left of the image. In reality, however, interactions between galaxies happen over very long time periods, and galaxies rarely collide head-on with one another. It is also unclear whether the galaxy to the lower left is actually interacting with the other two, although they are so relatively close in space that it seems possible that they are. By happy coincidence, the collective interaction between these galaxies have caused the two on the upper right to form a shape, which from our Solar System's perspective, ressembles the starship known as the USS Enterprise from Star Trek! NGC 7764A, which lies about 425 million light years from Earth in the constellation Phoenix, is a fascinating example of just how awkward astronomical nomenclature can be. The three galaxies are individually referred to as NGC 7764A1, NGC 7764A2 and NGC 7764A3, and just to be really difficult, an entirely separate galaxy, named NGC 7764, sits in the skies about a Moon’s distance (as seen from Earth) away. This rather haphazard naming makes more sense when we consider that many of the catalogues for keeping track of celestial bodies were compiled well over 100 years ago, long before modern technology made standardising scientific terminology much easier. As it is, many astronomical objects have several different names, or might have names that are so similar to other objects’ names that they cause confusion.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The Grumman Mohawk began as a joint Army-Marine program through the then-Navy Bureau of Aeronautics (BuAer), for an observation/attack plane that would outperform the light and vulnerable Cessna L-19 Bird Dog. In June 1956, the Army issued Type Specification TS145, which called for the development and procurement of a two-seat, twin turboprop aircraft designed to operate from small, unimproved fields under all weather conditions. It would be faster, with greater firepower, and heavier armor than the Bird Dog, which had proved very vulnerable during the Korean War.
The Mohawk's mission would include observation, artillery spotting, air control, emergency resupply, naval target spotting, liaison, and radiological monitoring. The Navy specified that the aircraft had to be capable of operating from small "jeep" escort class carriers (CVEs). The DoD selected Grumman Aircraft Corporation's G-134 design as the winner of the competition in 1957. Marine requirements contributed an unusual feature to the design: since the Marines were authorized to operate fixed-wing aircraft in the close air support (CAS) role, the mockup featured underwing pylons for rockets, bombs, and other stores, and this caused a lot of discord. The Air Force did not like the armament capability of the Mohawk and tried to get it removed. On the other side, the Marines did not want the sophisticated sensors the Army wanted, so when their Navy sponsors opted to buy a fleet oil tanker, they eventually dropped from the program altogether. The Army continued with armed Mohawks (and the resulting competence controversy with the Air Force) and also developed cargo pods that could be dropped from underwing hard points to resupply troops in emergencies.
In mid-1961, the first Mohawks to serve with U.S. forces overseas were delivered to the 7th Army at Sandhofen Airfield near Mannheim, Germany. Before its formal acceptance, the camera-carrying AO-1AF was flown on a tour of 29 European airfields to display it to the U.S. Army field commanders and potential European customers. In addition to their Vietnam and European service, SLAR-equipped Mohawks began operational missions in 1963 patrolling the Korean Demilitarized Zone.
Germany and France showed early interest in the Mohawk, and two OV-1s were field-tested by both nations over the course of several months. No direct orders resulted, though, but the German Bundesheer (Army) was impressed by the type’s performance and its capability as an observation and reconnaissance platform. Grumman even signed a license production agreement with the French manufacturer Breguet Aviation in exchange for American rights to the Atlantic maritime patrol aircraft, but no production orders followed.
This could have been the end of the OV-1 in Europe, but in 1977 the German government, primarily the interior ministry and its intelligence agency, the Bundesnachrichtendienst (BND), showed interest in a light and agile SIGINT/ELINT platform that could fly surveillance missions along the inner-German border to the GDR and also to Czechoslovakia. Beyond visual reconnaissance with cameras and IR sensors, the aircraft was to be specifically able to identify and locate secret radio stations that were frequently operated by Eastern Block agents (esp. by the GDR) all across Western Germany, but primarily close to the inner-German border due to the clandestine stations’ low power. The Bundeswehr already operated a small ELINT/ECM fleet, consisting of converted HFB 320 ‘Hansa’ business jets, but these were not suited for stealthy and inconspicuous low flight level missions that were envisioned, and they also lacked the ability to fly slowly enough to locate potential “radio nests”.
The pan and the objective were clear, but the ELINT project caused a long and severe political debate concerning the operator of such an aerial platform. Initially, the Bundesheer, who had already tested the OV-1, claimed responsibility, but the interior ministry in the form of the German customs department as well as the German police’s Federal Border Guard, the Bundesgrenzschutz and the Luftwaffe (the proper operator for fixed-wing aircraft within the German armed forces), wrestled for this competence. Internally, the debate and the project ran under the handle “Schimmelreiter” (literally “The Rider on the White Horse”), after a northern German legendary figure, which eventually became the ELINT system’s semi-official name after it had been revealed to the public. After much tossing, in 1979 the decision was made to procure five refurbished U.S. Army OV-1As, tailored to the German needs and – after long internal debates – operate them by the Luftwaffe.
The former American aircraft were hybrids: they still had the OV-1A’s original short wings, but already the OV-1D’s stronger engines and its internal pallet system for interchangeable electronics. The machines received the designation OV-1G (for Germany) and were delivered in early 1980 via ship without any sensors or cameras. These were of Western German origin, developed and fitted locally, tailored to the special border surveillance needs.
The installation and testing of the “Schimmelreiter” ELINT suite lasted until 1982. It was based on a Raytheon TI Systems emitter locator system, but it was locally adapted by AEG-Telefunken to the airframe and the Bundeswehr’s special tasks and needs. The system’s hardware was stowed in the fuselage, its sensor arrays were mounted into a pair of underwing nacelles, which occupied the OV-1’s standard hardpoints, allowing a full 360° coverage. In order to cool the electronics suite and regulate the climate in the internal equipment bays, the OV-1G received a powerful heat exchanger, mounted under a wedge-shaped fairing on the spine in front of the tail – the most obvious difference of this type from its American brethren. The exact specifications of the “Schimmelreiter” ELINT suite remained classified, but special emphasis was placed upon COMINT (Communications Intelligence), a sub-category of signals intelligence that engages in dealing with messages or voice information derived from the interception of foreign communications. Even though the “Schimmelreiter” suite was the OV-1Gs’ primary reconnaissance tool, the whole system could be quickly de-installed for other sensor packs and reconnaissance tasks (even though this never happened), or augmented by single modules, what made upgrades and mission specialization easy. Beyond the ELINT suite, the OV-1G could be outfitted with cameras and other sensors on exchangeable pallets in the fuselage, too. This typically included a panoramic camera in a wedge-shaped ventral fairing, which would visually document the emitter sensors’ recordings.
A special feature of the German OV-1s was the integration of a brand new, NATO-compatible “Link-16” data link system via a MIDS-LVT (Multifunctional Information Distribution System). Even though this later became a standard for military systems, the OV-1G broke the ground for this innovative technology. The MIDS was an advanced command, control, communications, computing and intelligence (C4I) system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements. Outwardly, the MIDS was only recognizable through a shallow antenna blister behind the cockpit.
Even though the OV-1Gs initially retained their former American uniform olive drab livery upon delivery and outfitting in German service, they soon received a new wraparound camouflage for their dedicated low-level role in green and black (Luftwaffe Norm 83 standard), which was better suited for the European theatre of operations. In Luftwaffe service, the OV-1Gs received the tactical codes 18+01-05 and the small fleet was allocated to the Aufklärungsgeschwader (AG) 51 “Immelmann”, where the machines formed, beyond two squadrons with RF-4E Phantom IIs, an independent 3rd squadron. This small unit was from the start based as a detachment at Lechfeld, located in Bavaria/Southern Germany, instead of AG 51’s home airbase Bremgarten in South-Western Germany, because Lechfeld was closer to the type’s typical theatre of operations along Western Germany’s Eastern borders. Another factor in favor of this different airbase was the fact that Lechfeld was, beyond Tornado IDS fighter bombers, also the home of the Luftwaffe’s seven HFB 320M ECM aircraft, operated by the JaBoG32’s 3rd squadron, so that the local maintenance crews were familiar with complex electronics and aircraft systems, and the base’s security level was appropriate, too.
With the end of the Cold War in 1990, the OV-1Gs role and field of operation gradually shifted further eastwards. With the inner-German Iron Curtain gone, the machines were now frequently operated along the Polish and Czech Republic border, as well as in international airspace over the Baltic Sea, monitoring the radar activities along the coastlines and esp. the activities of Russian Navy ships that operated from Kaliningrad and Saint Petersburg. For these missions, the machines were frequently deployed to the “new” air bases Laage and Holzdorf in Eastern Germany.
In American service, the OV-1s were retired from Europe in 1992 and from operational U.S. Army service in 1996. In Germany, the OV-1 was kept in service for a considerably longer time – with little problems, since the OV-1 airframes had relatively few flying hours on their clocks. The Luftwaffe’s service level for the aircraft was high and spare parts remained easy to obtain from the USA, and there were still OV-1 parts in USAF storage in Western German bases.
The German HFB 320M fleet was retired between 1993 and 1994 and, in part, replaced by the Tornado ECR. At the same time AG 51 was dissolved and the OV-1Gs were nominally re-allocated to JaboG 32/3. With this unit the OV-1Gs remained operational until 2010, undergoing constant updates and equipment changes. For instance, the machines received in 1995 a powerful FLIR sensor in a small turret in the aircraft’s nose, which improved the aircraft’s all-weather reconnaissance capabilities and was intended to spot hidden radio posts even under all-weather/night conditions, once their signal was recognized and located. The aircrafts’ radio emitter locator system was updated several times, too, and, as a passive defensive measure against heat-guided air-to-air missiles/MANPADS, an IR jammer was added, extending the fuselage beyond the tail. These machines received the suffix “Phase II”, even though all five aircraft were updated the same way.
Reports that the OV-1Gs were furthermore retrofitted with the avionics to mount and launch AIM-9 Sidewinder AAMs under the wing tips for self-defense remained unconfirmed, even more so because no aircraft was ever seen carrying arms – neither the AIM-9 nor anything else. Plans to make the OV-1Gs capable of carrying the Luftwaffe’s AGM-65 Maverick never went beyond the drawing board, either. However, BOZ chaff/flare dispenser pods and Cerberus ECM pods were occasionally seen on the ventral pylons from 1998 onwards.
No OV-1G was lost during the type’s career in Luftwaffe service, and after the end of the airframes’ service life, all five German OV-1Gs were scrapped in 2011. There was, due to worsening budget restraints, no direct successor, even though the maritime surveillance duties were taken over by Dornier Do 228/NGs operated by the German Marineflieger (naval air arm).

Typically, no offensive armament was carried, even though bombs or gun/missile pods were possible.
The kit and its assembly:
This build became a submission to the “Reconnaissance” Group Build at whatifmodellers.com in July 2021, and it spins further real-world events. Germany actually tested two OV-1s in the Sixties (by the German Army/Bundesheer, not by the air force), but the type was not procured or operated. The test aircraft carried a glossy, olive drab livery (US standard, I think) with German national markings.
However, having a vintage Hasegawa OV-1A in the stash, I wondered what an operational German OV-1 might have looked like, especially if it had been operated into the Eighties and beyond, in the contemporary Norm 83 paint scheme? This led to this purely fictional OV-1G.
The kit was mostly built OOB, and the building experience was rather so-so – after all, it’s a pretty old mold/boxing (in my case the Hasegawa/Hales kit is from 1978, the mold is from 1968!). Just a few things were modified/added in order to tweak the standard, short-winged OV-1A into something more modern and sophisticated.
When searching for a solution to mount some ELINT sensor arrays, I did not want to copy the OV-1B’s characteristic offset, ventral SLAR fairing. I rather settled for the late RV-1D’s solution with sensor pods under the outer wings. Unfortunately, the OV-1A kit came with the type’s original short wings, so that the pods had to occupy the inner underwing pair of hardpoints. The pods were scratched from square styrene profiles and putty, so that they received a unique look. The Mohawk’s pair of ventral hardpoints were mounted, but – after considering some drop tanks or an ECM pod there - left empty, so that the field of view for the ventral panoramic camera would not be obscured.
Other small additions are some radar warning sensor bumps on the nose, some extra antennae, a shallow bulge for the MIDS antenna on the spine, the FLIR turret on the nose (with parts from an Italeri AH-1 and a Kangnam Yak-38!), and I added a tail stinger for a retrofitted (scratched) IR decoy device, inspired by the American AN/ALG-147. This once was a Matchbox SNEB unguided missile pod.
Painting and markings:
For the intended era, the German Norm 83 paint scheme, which is still in use today on several Luftwaffe types like the Transall, PAH-2 or CH-53, appeared like a natural choice. It’s a tri-color wraparound scheme, consisting of RAL 6003 (Olivgrün), FS 34097 (Forest Green) and RAL 7021 (Teerschwarz). The paints I used are Humbrol 86 (which is supposed to be a WWI version of RAL 6003, it lacks IMHO yellow but has good contrast to the other tones), Humbrol 116 and Revell 9. The pattern itself was adapted from the German Luftwaffe’s Dornier Do 28D “Skyservants” with Norm 83 camouflage, because of the type’s similar outlines.
A black ink washing was applied for light weathering, plus some post-shading of panels with lighter shades of the basic camouflage tones for a more plastic look. The cockpit interior was painted in light grey (Humbrol 167), while the landing gear and the interior of the air brakes became white. The scratched SLAR pods became light grey, with flat di-electric panels in medium grey (created with decal material).
The cockpit interior was painted in a rather light grey (Humbrol 167), the pilots received typical olive drab Luftwaffe overalls, one with a white “bone dome” and the other with a more modern light grey helmet.
The decals were improvised. National markings and tactical codes came from TL Modellbau sheets, the AG 51 emblems were taken from a Hasegawa RF-4E sheet. The black walkways were taken from the Mohak’s OOB sheet, the black de-icer leading edges on wings and tail were created with generic black decal material. Finally, the model was sealed with a coat of matt acrylic varnish (Italeri).
An interesting result, and the hybrid paint scheme with the additional desert camouflage really makes the aircraft an unusual sight, adding to its credibility.
With the lightweight aluminium front and rear axles from the BMW M3/M4 models, forged 19-inch aluminium wheels with mixed-size tyres, M Servotronic steering with two settings and suitably effective M compound brakes, the new BMW M2 Coupe has raised the bar once again in the compact high-performance sports car segment when it comes to driving dynamics. The electronically controlled Active M Differential, which optimises traction and directional stability, also plays a significant role here. And even greater driving pleasure is on the cards when the Dynamic Stability Control system’s M Dynamic Mode (MDM) is activated. MDM allows wheel slip and therefore moderate, controlled drifts on the track.

Saturn is by far the solar system’s most photogenic planet, and in this latest Hubble Space Telescope snapshot it is especially so because Saturn’s magnificent ring system is near its maximum tilt toward Earth (which was in 2017).
Hubble was used to observe the planet on June 6, 2018, when Saturn was only approximately 1.36 billion miles from Earth, nearly as close to us as it ever gets.
Saturn was photographed as it approached a June 27 opposition, when the planet is directly opposite to the Sun in the night sky and is at its yearly closest distance to the Earth. Though all of the gas giants boast rings, Saturn’s are the largest and most spectacular, stretching out eight times the radius of the planet.
Saturn’s stunning rings were first identified as a continuous disk around the planet by Dutch astronomer Christiaan Huygens in 1655. 325 years later, NASA’s Voyager 1 spacecraft flyby of Saturn resolved thousands of thin, fine ringlets. Data from NASA’s Cassini mission suggests the rings formed 200 million years ago, roughly around the time of the dinosaurs and Earth’s Jurassic period. The gravitational disintegration of one of Saturn’s small moons created myriad icy debris particles, and collisions today likely continually replenish the rings.
Visible in this Hubble image are the classic rings as recorded by early skywatchers. From the outside in are the A ring with the Encke Gap, the Cassini Division, the B ring, and the C ring with the Maxwell Gap.
Saturn’s appearance changes due to its seasons, caused by the planet’s 27-degree axial tilt. It is now summer in Saturn’s northern hemisphere and the atmosphere is more active. This may be responsible for a string of bright clouds visible near the northern polar region that are the remnants of a disintegrating storm. Small, mid-latitude puffs of clouds are also visible. Hubble’s view also resolves a hexagonal pattern around the north pole, a stable and persistent wind feature discovered during the Voyager flyby in 1981.
Saturn’s colors come from hydrocarbon hazes above the ammonia crystals in the upper cloud layers. Unseen lower-level clouds are either ammonium hydrosulfide or water. The planet’s banded structure is caused by the winds and the clouds at different altitudes.
This is the first image of Saturn taken as part of the Outer Planet Atmospheres Legacy (OPAL) project. OPAL is helping scientists understand the atmospheric dynamics and evolution of our solar system’s gas giant planets.
+++ DISCLAIMER +++
Nothing you see here is real, even though the model, the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
In the aftermath of the Second World War, Sweden required a strong air defense, utilizing the newly developed jet propulsion technology. This led to a pair of proposals being issued by the Saab design team, led by Lars Brising. The first of these, codenamed R101, was a cigar-shaped aircraft, which bore a resemblance to the American Lockheed P-80 Shooting Star. The second design, which would later be picked as the winner, was a barrel-shaped design, codenamed R 1001, which proved to be both faster and more agile upon closer study.
The original R 1001 concept had been designed around a mostly straight wing, but after Swedish engineers had obtained German research data on swept-wing designs, the prototype was altered to incorporate a 25° sweep. In order to make the wing as thin as possible, Saab elected to locate the retractable undercarriage in the aircraft's fuselage rather than into the wings.
Extensive wind tunnel testing performed at the Swedish Royal University of Technology and by the National Aeronautical Research Institute had also influenced aspects of the aircraft's aerodynamics, such as stability and trim across the aircraft's speed range. In order to test the design of the swept wing further and avoid any surprises, it was decided to modify a single Saab Safir. It received the designation Saab 201 and a full-scale R 1001 wing for a series of flight tests. The first 'final' sketches of the aircraft, incorporating the new information, was drawn in January 1946.
The originally envisioned powerplant for the new fighter type was the de Havilland Goblin turbojet engine. However, in December 1945, information on the newer and more powerful de Havilland Ghost engine became available. The new engine was deemed to be ideal for Saab's in-development aircraft, as not only did the Ghost engine had provisions for the use of a central circular air intake, the overall diameter of the engine was favorable for the planned fuselage dimensions, too. Thus, following negotiations between de Havilland and Saab, the Ghost engine was selected to power the type instead and built in license as the RM 2.
By February 1946 the main outline of the proposed aircraft had been clearly defined. In Autumn 1946, following the resolution of all major questions of principal and the completion of the project specification, the Swedish Air Force formally ordered the completion of the design and that three prototype aircraft be produced, giving the proposed type the designation J 29.
On 1 September 1948, the first of the Saab 29 prototypes conducted its maiden flight, which lasted for half an hour. Because of the shape of its fuselage, the Saab J 29 quickly received the nickname "Flygande Tunnan" ("The Flying Barrel"), or "Tunnan" ("The Barrel") for short. While the demeaning nickname was not appreciated by Saab, its short form was eventually officially adopted.
A total of four prototypes were built for the aircraft's test program. The first two lacked armament, carrying heavy test equipment instead, while the third prototype was armed with four 20mm automatic guns. Various different aerodynamic arrangements were tested, such as air brakes being installed either upon the fuselage or on the wings aft of the rear spar, along with both combined and conventional aileron/flap arrangements.
The flight test program revealed that the J 29 prototypes were capable of reaching and exceeding the maximum permissible Mach number for which they had been designed, and the flight performance figures gathered were found to be typically in excess of the predicted values.
In 1948 production of the type commenced and in May 1951 the first deliveries of operational production aircraft were received by F 13 Norrköping. The J 29 proved to be very successful and several variants and updates of the Tunnan were produced, including a dedicated reconnaissance variant and a dedicated all-weather fighter with an on-board radar, the J 29D.
The J 29D variant originally started its career as a single prototype to test the Ghost RM 2A afterburner turbojet with 27.5 kN (2,800 kgp/6,175 lbf). The new engine dramatically improved the Tunnan’s performance, esp. concerning the start phase, acceleration and climb, and was eventually adopted for the whole J 29 fighter fleet in an update program, leading to the J 29F variant.
However, at the time of the RM 2A trials, Sweden was more and more in need for a suitable all-weather aerial defense for its vast, neutral airspace in the vicinity of the Soviet Union. Only a single flight of the Swedish Air Force, F1 in Hässlö, operated roundabout thirty radar-equipped fighters, and these were outdated De Havilland Mosquito night fighters (locally designated J 30).
The highly successful J 29 was soon considered as a potential air-intercept radar carrier, offering a much more up-tp-date performance and deterrent potential against would-be intruders. Consequently, Saab started the development of an indigenous all-weather fighter on the basis of the Tunnan (originally coded “J 29R”). The work started with aerodynamic trials of different radome designs and placements on a Tunnan’s nose, e .g. inside of the circular air intake opening or above it. No major drawbacks were identified, and in 1955 the decision was made to convert thirty J 29B daylight fighters for the all weather/night fighter role. These machines officially inherited the designation J 29D.
The J 29D’s compact radar, called the PS-43/T, was designed by CSF (Compagnie Generale de Telegrahpi Sans Fil) in France after the Swedish specification. It had a wavelength of 3 cm with an effect of 100 kW, and it was to have a spiral scan pattern. Range was 15-20 km, only a slight improved against the Mosquitos’ bulky SCR-720B radar set, which only had a range of 12-16km. But the system’s compact size and the ability to be operated by the pilot alone meant a serious step forward. 34 sets were delivered together with blueprints in 1956, and the PS-43 radar system was later modified and adapted to the Saab 32 Lansen, too.
The structural modifications for the radar-equipped Tunnan were carried out in the course of the ensuing J 29F update program, which had started in 1954. Beyond the afterburner engine and dogtooth wing updates for the day fighters, the J 29D also received a re-designed nose section which now featured a thimble radome for the PS-43/T, integrated into the upper air intake lip, reminiscent of the F-86D’s arrangement. The air intake itself kept the original circular diameter, but the opening was slightly wider, raked forward and featured a sharper lip, for an improved airflow under the radome. Overall performance of the J 29 did not suffer, and the conversion took place swiftly thanks to a simple replacement of the nose section in front of the windscreen and the installation of a shielded tracking monitor in the cockpit.
Experiments with a heavier cannon armament (consisting of four, long-barreled 30mm guns in the lower fuselage) for the J 29 in general were conducted in parallel, too. But, despite showing no negative effect on the J 29’s handling or performance, this upgrade was not introduced to any of the J 29 variants in service and so the J 29D kept its original four 20mm cannon as main armament, too. Additional ordnance consisted of optional racks with 75 mm/3 in air-to-air rockets under the inner wings against large aerial targets like bombers. A pair of drop tanks could be carried on the outer pylons, too, and they were frequently carried in order to extend range and loiter time. Other loads, including bombs or unguided air-to-ground missiles, were possible, but never carried except for in practice.
The last converted J 29D was delivered back to the Swedish Air Force in late 1956, just in time to replace the last active J 30 Mosquitos in service, which had been gradually phased out since 1953. In parallel, the radar-equipped J 33 Venom was introduced into service, too, since the small number of J 29Ds had in the meantime turned out to be far from sufficient to effectively cover the Swedish air space against large numbers of ever faster jet bombers and reconnaissance aircraft. The J 29D fulfilled its role and duty well, though, and was just as popular as the daylight fighter versions.
Initially, all J 29D were delivered in bare metal finish, but they were soon adorned with additional markings on fin and wing tips for easier recognition and formation flights. A few all-weather fighters of F1 Flygflottil experimentally received the blue/green camouflage which had been adopted for the S 29C reconnaissance aircraft, but this was found to be ineffective at the typical altitudes the interceptors would operate. As a consequence, the scheme was quickly changed into the much lighter livery of the former J 30 and J 33 fighters, although the bare metal undersides and the formation markings under the wing tips were retained – even though this practice was confined to F 1 and not consequently carried out among all of the fighter squadron's J 29Ds. Some J 29D furthermore carried various forms of black ID bands for quick identification in war games, but unlike the day fighters, these markings were limited to the undersides only.
From 1963 onwards all frontline J 29Fs were equipped with AIM-9 Sidewinder infrared-seeking air-to-air missiles, designated Rb 24 in Swedish service. This update was also carried out among the J 29D fleet, and the new, guided missiles considerably improved the aircraft’s capabilities.
Anyway, the J 29D’s small number remained a fundamental problem that prevented bigger success or even export sales, and due to the quick technical advances, the J 29D remained only a stopgap solution. The much more capable Saab 32 Lansen had been under development and its dedicated all-weather fighter variant, the J 32B, had already entered service in 1958, replacing the mixed and outdated lot of radar-equipped fighters in Swedish service.
Nevertheless, the J 29D soldiered on, together with the rest of the J 29F and S 29C fleet, until 1970, even though not in front line duties anymore.

Performance:
Maximum speed: 1,060 km/h (660 mph)

Typically, a pair of 400-liter (106 US gallon) or 500-liter (132 US gallon) drop tanks was carried on the outer “wet” pylons
Further air-to-air ordnance initially consisted of 75 mm (3 in) air-to-air rockets, from 1963 onwards the J 29D could also carry up to 4x Rb 24 (AIM-9B Sidewinder) IR-guided air-to-air missiles.
Optionally (but never carried in service), the J 29D could also deploy a wide range of bombs and unguided missiles, including 145 mm (5.8 in) anti-armor rockets, 150 mm (6 in) HE (high-explosive) rockets or 180 mm (7.2 in) HE anti-ship rockets
The kit and its assembly:
Sweden is a prolific whiffing territory, and the Saab 29 offers some interesting options. The all-weather Tunnan was a real Saab project, and things actually got as far as the aforementioned radome shape test stage. But eventually the project was fully dropped, since Saab had been busy with standard J 29 production and conversions, so that this aircraft never materialized, just as the projected side-by-side trainer Sk 29 of the same era.
However, I recently came across a nice Saab 29 book which also covers some projects – including drawings of the radar-equipped Tunnan that never was. My converted model with the thimble radome and the raked air intake is based on these drawings.
The basic kit is the Heller Saab 29, which I deem superior to the Matchbox Tunnan, with its mix of raised and engraved panel lines and overall rather soft detail (despite the surprisingly nice cockpit). Anyway,, the Heller kit has its flaws, too, e. g. a generally weak material thickness, lack of locator pins or other stabilizing aids and some sinkholes here and there.
The kit was built mostly OOB, with as much lead in the gun tray as possible - and it actually stands on its own three feet/wheels! The only major change is the modified nose section. It sounds simple to graft a radome onto the Tunnan's nose, but the rhinoplasty was challenging. The whole front end had to be renewed, based on the profile drawings and sketches at hand.
The thimble radome is actually a recycled drop tank front end from a Hasegawa F6F Hellcat. The raked, lower aitr intake lip comes from a Matchbox Mystère IVA - but it lost its splitter, was reshaped and had the OOB air intake duct glued into place from behind. Once the intake was glued into its place, a wedge opeing was cut into the area in front of the canopy and the drop tank radome adapted to the gap, a step-by-step approach, since I wanted to have the radome slightly protrude into the airtake, but also keep a staright line in front of the windscreen.
Additional details include new pitots on the wing tips and some additional antennae. The heat shield for the afterburner engine is OOB, as well as the streamlined drop tanks and their pylons. I just added an additional pair of pylons (from an Acedamy MiG-23) to the inner wing, holding a pair of AIM-9Bs.
Painting and markings:
Finding a suitable, yet “different” scheme for the J 29 night fighter was not easy; most J 29 were left in bare metal, some carried dark green upper surfaces and some S 29C wore a paint scheme in olive green and dark blue. I eventually settled for the RAF style paint scheme that had been adopted with the J 30 Mosquito and J 33 Venom night fighters – not spectacular, but different from the Swedish early Sixties norm, and it subtly underlines the J 29D’s role.
The scheme was lent from RAF Venom night fighters (which was used on the Swedish J 33, too), and of the upper surfaces I used RAF tones, too: Humbrol 163 (Dark Green) and 165 (Medium Sea Grey). However, I did not want to use the grey on the lower surfaces, since I found that scheme a bit too uniform and British, so I painted the lower surfaces in NMF, with a waterline at medium height - higher than the camouflaged S 29C’s and lower than the early, camouflaged J 29A fighters (with an experimental all-green upper surface).
The bare metal finish was created with acrylic Aluminum (Revell 99) and Polished and Matt Aluminum Metallizer (Humbrol) added on top, highlighting single panels. Around the engine bay and the exhaust, a base with Iron (Revell 91) was laid down, with Steel Metallizer (Modelmaster) on top.
Under the wing tips, green formation markings (again Humbrol 163) were added, as well as black ID stripes (cut from generic decal sheet material). Other, Swedish adornment, like the roundels, codes or squadron markings, was taken from the OOB sheet, a PrintScale sheet for the J 29 and leftover decals from a Heller J 21.
Interior details were painted according to Swedish standard, thankfully there are many good pictures available. The cockpit interior became grey-green (Revell 67 comes very close to the real thing) with light grey dashboard and side consoles. The landing gear wells medium (Revell 57) grey with some dry-brushed Aluminum, while the wheel discs became grey-green, too.
An interesting result, through relatively little effort: the dog nose changes the look of the tubby J 29 a lot, it looks much sleeker and somewhat German now – but somehow also more retro than the original aircraft? The different paint scheme looks unusual, too, despite being relatively down-to-earth. This will certainly not be my last modified J 29, a two-seat trainer would certainly be another cool and reality based Tunnan whif?

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

Some background:
The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.
The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.
Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.
Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.
After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.
The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.
The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.
Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.
The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.
To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.
The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.
The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.
Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.
However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.
On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.
A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.
These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.
In the meantime, tests with the SG 104 progressed and several modifications were tested on different EKdo 104's Do 217 F-0s. One major upgrade was a further strengthening of the tail section, which added another 200 kg (440 lb) to the aircraft's dry weight. Furthermore, at least three aircraft were outfitted with additional dive brakes under the outer wings, so that the dive could be better controlled and intercepted. these aircraft, however, lost their plumbed underwing hardpoints, but these were only ever used for drop tanks during transfer flights - a loaded SG 104 precluded any other ordnance. On two other aircraft the SG 104 was modified to test different muzzle brakes and deflectors for the rear-facing opening, so that the gun blast was more effectively guided away from the airframe to prevent instability and structural damage. For instance, one machine was equipped with a bifurcated blast deflector that directed the rearward gasses partly sideways, away from the fuselage.
These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.
With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:
This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.
On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.
The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/
I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.
The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.
All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.
The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.
Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.
In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.
Painting and markings:
This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.
I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.
Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.
To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).
RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).
A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.
The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.
After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.
Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The ZSU-37-6 (“ZSU” stands for Zenitnaya Samokhodnaya Ustanovka / Зенитная Самоходная Установка = "anti-aircraft self-propelled mount"), also known as Object 511 during its development phase and later also as “ZSU-37-6 / Лена”, was a prototype for a lightly armored Soviet self-propelled, radar guided anti-aircraft weapon system that was to replace the cannon-armed ZSU-23-4 “Shilka” SPAAG.
The development of the "Shilka" began in 1957 and the vehicle was brought into service in 1965. The ZSU-23-4 was intended for AA defense of military facilities, troops, and mechanized columns on the march. The ZSU-23-4 combined a proven radar system, the non-amphibious chassis based on the GM-575 tracked vehicle, and four 23 mm autocannons. This delivered a highly effective combination of mobility with heavy firepower and considerable accuracy, outclassing all NATO anti-aircraft guns at the time. The system was widely fielded throughout the Warsaw Pact and among other pro-Soviet states. Around 2,500 ZSU-23-4s, of the total 6,500 produced, were exported to 23 countries.
The development of a potential successor started in 1970. At the request of the Soviet Ministry of Defense, the KBP Instrument Design Bureau in Tula started work on a new mobile anti-aircraft system as a replacement for the 23mm ZSU-23-4. The project was undertaken to improve on the observed shortcomings of the ZSU-23-4 (short range and no early warning) and to counter new ground attack aircraft in development, such as the A-10 Thunderbolt II, which was designed to be highly resistant to 23 mm cannons.
KBP studies demonstrated that a cannon of at least 30 mm caliber was necessary to counter these threats, and that a bigger caliber weapon would offer some more benefits. Firstly, to destroy a given target, such a weapon would only require from a third to a half of the number of shells that the ZSU-23-4’s 23 mm cannon would need. Secondly, comparison tests revealed that firing with an identical mass of 30 mm projectiles instead of 23 mm ammunition at a MiG-17 (or similarly at NATO's Hawker Hunter or Fiat G.91…) flying at 300 m/s would result in a 1.5 times greater kill probability. An increase in the maximum engagement altitude from 2,000 to 4,000 m and higher effectiveness when engaging lightly armored ground targets were also cited as potential benefits.
The initial requirements set for the new mobile weapon system were to achieve twice the performance in terms of the ZSU-23-4’s range, altitude and combat effectiveness. Additionally, the system should have a reaction time, from target acquisition to firing, no greater than 10 seconds, so that enemy helicopters that “popped up” from behind covers and launched fire-and-forget weapons at tanks or similar targets could be engaged effectively.
From these specifications KBP developed two schools of thought that proposed different concepts and respective vehicle prototypes: One design team followed the idea of an anti-aircraft complex with mixed cannon and missile armament, which made it effective against both low and high-flying targets but sacrificed short-range firepower. The alternative proposed by another team was a weapon carrier armed only with a heavy gatling-type gun, tailored to counter targets flying at low altitudes, esp. helicopters, filling a similar niche as the ZSU-23-4 and leaving medium to high altitude targets to specialized anti-aircraft missiles. The latter became soon known as “Object 511”.
Object 511 was based on the tracked and only lightly armored GM-577 chassis, produced by Minsk Tractor Works (MTZ). It featured six road wheels on each side, a drive sprocket at the rear and three return rollers. The chassis was primarily chosen because it was already in use for other anti-aircraft systems like the 2K11 “Krug” complex and could be taken more or less “off the rack”. A new feature was a hydropneumatic suspension, which was chosen in order to stabilize the chassis as firing platform and also to cope with the considerably higher all-up weight of the vehicle (27 tons vs. the ZSU-23-4’s 19 tons). Other standard equipment of Object 511 included heating, ventilation, navigational equipment, night vision aids, a 1V116 intercom and an external communications system with an R-173 receiver.
The hull was - as the entire vehicle - protected from small arms fire (7,62mm) and shell splinters, but not heavily armored. An NBC protection system was integrated into the chassis, as well as an automatic fire suppression system and an automatic gear change. The main engine bay, initially with a 2V-06-2 water-cooled multi-fuel diesel engine with 450 hp (331 kW) was in the rear. It was later replaced by a more powerful variant of the same engine with 510 hp (380 kW).
The driver sat in the front on the left side, with a small gas turbine APU to his right to operate the radar and hydraulic systems independently from the main engine.
Between these hull segments, the chassis carried a horseshoe-shaped turret with full 360° rotation. It was relatively large and covered more than the half of the hull’s roof, because it held the SPAAGs main armament and ammunition supply, the search and tracking radar equipment as well as a crew of two: the commander with a cupola on the right side and the gunner/radar operator on the left side, with the cannon installation and its feeding system between them. In fact, it was so large that Object 511’s engine bay was only accessible when the turret was rotated 90° to the side – unacceptable for an in-service vehicle (which would probably have been based on a bigger chassis), but accepted for the prototype which was rather focused on the turret and its complex weapon and radar systems.
Object 511’s centerpiece was the newly-developed Gryazev-Shipunov GSh-6-37 cannon, a heavy and experimental six-barreled 37mm gatling gun. This air-cooled weapon with electrical ignition was an upscaled version of the naval AO-18 30mm gun, which was part of an automated air defense system for ships, the AK-630 CIWS complex. Unlike most modern American rotary cannons, the GSh-6-37 was gas-operated rather than hydraulically driven, allowing it to "spin up" to maximum rate of fire more quickly. This resulted in more rounds and therefore weight of fire to be placed on target in a short burst, reduced reaction time and allowed hits even in a very small enemy engagement window.
The GSh-6-37 itself weighed around 524 kg (1.154 lb), the whole system, including the feed system and a full magazine, weighed 7,493 pounds (3,401 kg). The weapon had a total length of 5.01 m (16’ 7“), its barrels were 2.81 m (9’ 2½”) long. In Object 511’s turret it had an elevation between +80° and -11°, moving at 60°/sec, and a full turret rotation only took 3 seconds. Rate of fire was 4,500 rounds per minute, even though up to 5.500 RPM were theoretically possible and could be cleared with an emergency setting. However, the weapon would typically only fire short bursts of roundabout 50 rounds each, or longer bursts of 1-2 (maximum) seconds to save ammunition and to avoid overheating and damage – initially only to the barrels, but later also to avoid collateral damage from weapon operation itself (see below). Against ground targets and for prolonged, safe fire, the rate of fire could alternatively be limited to 150 RPM.
The GSh-6-37 fired 1.09 kg shells (each 338mm long) at 1,070 m/s (3.500 ft/s), developing a muzzle energy of 624,000 joules. This resulted in an effective range of 6,000 m (19.650 ft) against aerial and 7,000 m (23.0000 ft) against ground targets. Maximum firing range was past 7,160 m (23,490 ft), with the projectiles self-destructing beyond that distance. In a 1 sec. burst, the weapon delivered an impressive weight of fire of almost 100 kg.
The GSh-6-37 was belt-fed, with a closed-circuit magazine to avoid spilling casings all around and hurting friendly troops in the SPAAG’s vicinity. Typical types of ammunition were OFZT (proximity-fused incendiary fragmentation) and BZT (armor-piercing tracer, able to penetrate more than 60 mm of 30° sloped steel armor at 1.000 m/3.275’ distance). Since there was only a single ammunition supply that could not be switched, these rounds were normally loaded in 3:1 ratio—three OFZT, then one BZT, every 10th BZT round marked with a tracer. Especially the fragmentation rounds dealt extensive collateral damage, as the sheer numbers of fragments from detonating shells was sufficient to damage aircraft flying within a 200-meter radius from the impact center. This, coupled with the high density of fire, created a very effective obstacle for aerial targets and ensured a high hit probability even upon a casual and hurried attack.
The gun was placed in the turret front’s center, held by a massive mount with hydraulic dampers. The internal ammunition supply in the back of the turret comprised a total of 1.600 rounds, but an additional 800 rounds could be added in an external reserve feed bin, attached to the back of the turret and connected to the internal belt magazine loop through a pair of ports in the turret’s rear, normally used to reload the GSh-6-37.
A rotating, electronically scanned E-band (10 kW power) target acquisition radar array was mounted on the rear top of the turret that, when combined with the turret front mounted J-band (150 kW power) mono-pulse tracking radar, its dish antenna hidden under a fiberglass fairing to the right of the main weapon, formed the 1RL144 (NATO: Hot Shot) pulse-Doppler 3D radar system. Alongside, the 1A26 digital computer, a laser rangefinder co-axial to the GSh-6-37, and the 1G30 angle measurement system formed the 1A27 targeting complex.
Object 511’s target acquisition offered a 360-degree field of view, a detection range of around 18 km and could detect targets flying as low as 15 m. The array could be folded down and stowed when in transit, lying flat on the turret’s roof. The tracking radar had a range of 16 km, and a C/D-band IFF system was also fitted. The radar system was highly protected against various types of interference and was able to work properly even if there were mountains on the horizon, regardless of the background. The system made it possible to fire the GSh-6-37 on the move, against targets with a maximum target speed of up to 500 m/s, and it had an impressive reaction time of only 6-8 seconds.
Thanks to its computerized fire control system, the 1A27 was highly automated and reduced the SPAAG’s crew to only three men, making a dedicated radar operator (as on the ZSU-23-4) superfluous and saving internal space in the large but still rather cramped turret.
Development of Object 511 and its systems were kicked-off in 1972 but immediately slowed down with the introduction of the 9K33 “Osa” missile system, which seemed to fill the same requirement but with greater missile performance. However, after some considerable debate it was felt that a purely missile-based system would not be as effective at dealing with very low flying attack helicopters attacking at short range with no warning, as had been proven so successful in the 1973 Arab-Israeli War. Since the reaction time of a gun system was around 8–10 seconds, compared to approximately 30 seconds for a missile-based system, development of Object 511 was restarted in 1973.
A fully functional prototype, now officially dubbed “ZSU-37-6“ to reflect its role and armament and christened “Лена” (Lena, after the Russian river in Siberia), was completed in 1975 at the Ulyanovsk Mechanical Factory, but it took until 1976 that the capricious weapon and the 1A27 radar system had been successfully integrated and made work. System testing and trials were conducted between September 1977 and December 1978 on the Donguzskiy range, where the vehicle was detected by American spy satellites and erroneously identified as a self-propelled artillery system with a fully rotating turret (similar to the American M109), as a potential successor for the SAU-122/2S1 Gvozdika or SAU-152/2S3 Akatsiya SPGs that had been introduced ten years earlier, with a lighter weapon of 100-120mm caliber and an autoloader in the large turret.
The tests at Donguzskiy yielded mixed results. While the 1A27 surveillance and acquisition radar complex turned out to be quite effective, the GSh-6-37 remained a constant source of problems. The gun was highly unreliable and afforded a high level of maintenance. Furthermore, it had a massive recoil of 6.250 kp/61 kN when fired (the American 30 mm GAU-8 Avenger “only” had a recoil of 4.082 kp/40 kN). As a result, targets acquired by the 1A27 system were frequently lost after a single burst of fire, so that they had to be tracked anew before the next shot could be placed.
To make matters even words, the GSh-6-37 was noted for its high and often uncomfortable vibration and extreme noise, internally and externally. Pressure shock waves from the gun muzzles made the presence of unprotected personnel in the weapon’s proximity hazardous. The GSh-6-37’s massive vibrations shook the whole vehicle and led to numerous radio and radar system failures, tearing or jamming of maintenance doors and access hatches and the cracking of optical sensors. The effects were so severe that the gun’s impact led after six months to fatigue cracks in the gun mount, the welded turret hull, fuel tanks and other systems. One spectacular and fateful showcase of the gun’s detrimental powers was a transmission failure during a field test/maneuver in summer 1978 – which unfortunately included top military brass spectators and other VIPs, who were consequently not convinced of the ZSU-37-6 and its weapon.
The GSh-6-37’s persisting vibration and recoil problems, as well as its general unreliability if it was not immaculately serviced, could not be satisfactorily overcome during the 2 years of state acceptance trials. Furthermore, the large and heavy turret severely hampered Object 511’s off-road performance and handling, due to the high center of gravity and the relatively small chassis, so that the weapon system’s full field potential could not be explored. Had it found its way into a serial production vehicle, it would certainly have been based on a bigger and heavier chassis, e.g. from an MBT. Other novel features tested with Object 511, e.g. the hydropneumatic suspension and the automated 1A27 fire control system, proved to be more successful.
However, the troublesome GSh-6-37 temporarily attained new interest in 1979 through the Soviet Union’s engagement in Afghanistan, because it became quickly clear that conventional battle tanks, with long-barreled, large caliber guns and a very limited lift angle were not suited against small targets in mountainous regions and for combat in confined areas like narrow valleys or settlements. The GSh-6-37 appeared as a promising alternative weapon, and plans were made to mount it in a more strongly armored turret onto a T-72 chassis. A wooden mockup turret was built, but the project was not proceeded further with. Nevertheless, the concept of an armored support vehicle with high firepower and alternative armament would persist and lead, in the course of the following years, to a number of prototypes that eventually spawned the BMPT "Terminator" Tank Support Fighting Vehicle.
More tests and attempts to cope with the gun mount continued on a limited basis through 1979, but in late 1980 trials and development of Object 511 and the GSh-6-37 were stopped altogether: the 2K22 “Tunguska” SPAAG with mixed armament, developed in parallel, was preferred and officially accepted into service. In its original form, the 2K22 was armed with four 9M311 (NATO: SA-19 “Grison”) short-range missiles in the ready-to-fire position and two 2A38 30mm autocannons, using the same 1A27 radar system as Object 511. The Tunguska entered into limited service from 1984, when the first batteries, now armed with eight missiles, were delivered to the army, and gradually replaced the ZSU-23-4.
Having become obsolete, the sole Object 511 prototype was retired in 1981 and mothballed. It is today part of the Military Technical Museum collection at Ivanovskaya, near Moscow, even though not part of the public exhibition and in a rather derelict state, waiting for restoration and eventual display.

The kit and its assembly:
This fictional SPAAG was intended as a submission to the “Prototypes” group build at whatifmodellers.com in August 2020. Inspiration came from a Trumpeter 1:72 2P25/SA-6 launch platform which I had recently acquired with a kit lot – primarily because of the chassis, which would lend itself for a conversion into “something else”.
The idea to build an anti-aircraft tank with a gatling gun came when I did research for my recent YA-14 build and its armament. When checking the American GAU-8 cannon from the A-10 I found that there had been plans to use this weapon for a short-range SPAAG (as a replacement for the US Army’s M163), and there had been plans for even heavier weapons in this role. For instance, there had been the T249 “Vigilante” prototype: This experimental system consisted of a 37 mm T250 six-barrel Gatling gun, mounted on a lengthened M113 armored personnel carrier platform, even though with a very limited ammunition supply, good only for 5 sec. of fire – it was just a conceptual test bed. But: why not create a Soviet counterpart? Even more so, since there is/was the real-world GSh-6-30 gatling gun as a potential weapon, which had, beyond use in the MiG-27, also been used in naval defense systems. Why not use/create an uprated/bigger version, too?
From this idea, things evolved in a straightforward fashion. The Trumpeter 2P25 chassis and hull were basically taken OOB, just the front was modified for a single driver position. However, the upper hull had to be changed in order to accept the new, large turret instead of the triple SA-6 launch array.
The new turret is a parts combination: The basis comes from a Revell 1:72 M109 howitzer kit, the 155 mm barrel was replaced with a QuickBoost 1:48 resin GSh-6-30 gun for a MiG-27, and a co-axial laser rangefinder (a piece of styrene) was added on a separate mount. Unfortunately, the Revell kit does not feature a movable gun barrel, so I decided to implant a functional joint, so that the model’s weapon could be displayed in raised and low position – primarily for the “action pictures”. The mechanism was scratched from styrene tubes and a piece of foamed plastic as a “brake” that holds the weapon in place and blocks the view into the turret from the front when the weapon is raised high up. The hinge was placed behind the OOB gun mantle, which was cut into two pieces and now works as in real life.
Further mods include the dish antenna for the tracking radar (a former tank wheel), placed on a disc-shaped pedestal onto the turret front’s right side, and the retractable rotating search radar antenna, scratched from various bits and pieces and mounted onto the rear of the turret – its roof had to be cleaned up to make suitable space next to the commander’s cupola.
Another challenge was the adaptation of the new turret to the hull, because the original SA-6 launch array has only a relatively small turret ring, and it is placed relatively far ahead on the hull. The new, massive turret had to be mounted further backwards, and the raised engine cowling on the back of the hull did not make things easier.
As a consequence, I had to move the SA-6 launcher ring bearing backwards, through a major surgical intervention in the hull roof (a square section was cut out, shortened, reversed and glued back again into the opening). In order to save the M109’s turret ring for later, I gave it a completely new turret floor and transplanted the small adapter ring from the SA-6 launch array to it. Another problem arose from the bulged engine cover: it had to be replaced with something flat, otherwise the turret would not have fitted. I was lucky to find a suitable donor in the spares box, from a Leopard 1 kit. More complex mods than expected, and thankfully most of the uglier changes are hidden under the huge turret. However, Object 511 looks pretty conclusive and menacing with everything in place, and the weapon is now movable in two axis’. The only flaw is a relatively wide gap between the turret and the hull, due to a step between the combat and engine section and the relatively narrow turret ring.
Painting and markings:
AFAIK, most Soviet tank prototypes in the Seventies/Eighties received a simple, uniform olive green livery, but ,while authentic, I found this to look rather boring. Since my “Object 511” would have taken part in military maneuvers, I decided to give it an Eighties Soviet Army three-tone camouflage, which was introduced during the late Eighties. It consisted of a relatively bright olive green, a light and cold bluish grey and black-grey, applied in large patches.
This scheme was also adapted by the late GDR’s Volksarmee (called “Verzerrungsanstrich” = “Distortion scheme”) and maybe – even though I am not certain – this special paint scheme might only have been used by Soviet troops based on GDR soil? However, it’s pretty unique and looks good, so I adapted it for the model.
Based upon visual guesstimates from real life pictures and some background info concerning NVA tank paint schemes, the basic colors became Humbrol 86 (Light Olive Green; RAL 6003), Revell 57 (Grey; RAL 7000) and Revell 06 (Tar Black; RAL 9021). Each vehicle had an individual paint scheme, in this case it was based on a real world NVA lorry.
On top of the basic colors, a washing with a mix of red brown and black acrylic paint was applied, and immediately dried with a soft cotton cloth so that it only remained in recesses and around edges, simulating dirt and dust. Some additional post-shading with lighter/brighter versions of the basic tones followed.
Decals came next – the Red Stars were a rather dramatic addition and came from the Trumpeter kit’s OOB sheet. The white “511” code on the flanks was created with white 3 mm letters from TL Modellbau.
The model received a light overall dry brushing treatment with light grey (Revell 75). As a finishing touch I added some branches as additional camouflage. These are bits of dried moss (collected on the local street), colorized with simple watercolors and attached with white glue. Finally, everything was sealed and stabilized with a coat of acrylic matt varnish and some pigments (a greyish-brown mix of various artist mineral pigments) were dusted into the running gear and onto the lower hull surfaces with a soft brush.
An effective kitbashing, and while mounting the different turret to the hull looks simple, the integration of unrelated hull and turret so that they actually fit and “work” was a rather fiddly task, and it’s effectively not obvious at all (which is good but “hides” the labour pains related to the mods). However, the result looks IMHO good, like a beefed-up ZSU-23-4 “Schilka”, just what this fictional tank model is supposed to depict.
Only one tulip bloomed this year and only one bud on this particular plant. The nice landscapers, however, did make the area surrounding the tree a bit wider, which was nice. They're also supposed to be handling the "irrigation" this year - hopefully they will not spray the majority of the sprinkler system's water into the middle of the street as it has in the past. And we got a nice new little plastic pink flag.

Some background:
The Grumman Mohawk began as a joint Army-Marine program through the then-Navy Bureau of Aeronautics (BuAer), for an observation/attack plane that would outperform the light and vulnerable Cessna L-19 Bird Dog. In June 1956, the Army issued Type Specification TS145, which called for the development and procurement of a two-seat, twin turboprop aircraft designed to operate from small, unimproved fields under all weather conditions. It would be faster, with greater firepower, and heavier armor than the Bird Dog, which had proved very vulnerable during the Korean War.
The Mohawk's mission would include observation, artillery spotting, air control, emergency resupply, naval target spotting, liaison, and radiological monitoring. The Navy specified that the aircraft had to be capable of operating from small "jeep" escort class carriers (CVEs). The DoD selected Grumman Aircraft Corporation's G-134 design as the winner of the competition in 1957. Marine requirements contributed an unusual feature to the design: since the Marines were authorized to operate fixed-wing aircraft in the close air support (CAS) role, the mockup featured underwing pylons for rockets, bombs, and other stores, and this caused a lot of discord. The Air Force did not like the armament capability of the Mohawk and tried to get it removed. On the other side, the Marines did not want the sophisticated sensors the Army wanted, so when their Navy sponsors opted to buy a fleet oil tanker, they eventually dropped from the program altogether. The Army continued with armed Mohawks (and the resulting competence controversy with the Air Force) and also developed cargo pods that could be dropped from underwing hard points to resupply troops in emergencies.
In mid-1961, the first Mohawks to serve with U.S. forces overseas were delivered to the 7th Army at Sandhofen Airfield near Mannheim, Germany. Before its formal acceptance, the camera-carrying AO-1AF was flown on a tour of 29 European airfields to display it to the U.S. Army field commanders and potential European customers. In addition to their Vietnam and European service, SLAR-equipped Mohawks began operational missions in 1963 patrolling the Korean Demilitarized Zone.
Germany and France showed early interest in the Mohawk, and two OV-1s were field-tested by both nations over the course of several months. No direct orders resulted, though, but the German Bundesheer (Army) was impressed by the type’s performance and its capability as an observation and reconnaissance platform. Grumman even signed a license production agreement with the French manufacturer Breguet Aviation in exchange for American rights to the Atlantic maritime patrol aircraft, but no production orders followed.
This could have been the end of the OV-1 in Europe, but in 1977 the German government, primarily the interior ministry and its intelligence agency, the Bundesnachrichtendienst (BND), showed interest in a light and agile SIGINT/ELINT platform that could fly surveillance missions along the inner-German border to the GDR and also to Czechoslovakia. Beyond visual reconnaissance with cameras and IR sensors, the aircraft was to be specifically able to identify and locate secret radio stations that were frequently operated by Eastern Block agents (esp. by the GDR) all across Western Germany, but primarily close to the inner-German border due to the clandestine stations’ low power. The Bundeswehr already operated a small ELINT/ECM fleet, consisting of converted HFB 320 ‘Hansa’ business jets, but these were not suited for stealthy and inconspicuous low flight level missions that were envisioned, and they also lacked the ability to fly slowly enough to locate potential “radio nests”.
The pan and the objective were clear, but the ELINT project caused a long and severe political debate concerning the operator of such an aerial platform. Initially, the Bundesheer, who had already tested the OV-1, claimed responsibility, but the interior ministry in the form of the German customs department as well as the German police’s Federal Border Guard, the Bundesgrenzschutz and the Luftwaffe (the proper operator for fixed-wing aircraft within the German armed forces), wrestled for this competence. Internally, the debate and the project ran under the handle “Schimmelreiter” (literally “The Rider on the White Horse”), after a northern German legendary figure, which eventually became the ELINT system’s semi-official name after it had been revealed to the public. After much tossing, in 1979 the decision was made to procure five refurbished U.S. Army OV-1As, tailored to the German needs and – after long internal debates – operate them by the Luftwaffe.
The former American aircraft were hybrids: they still had the OV-1A’s original short wings, but already the OV-1D’s stronger engines and its internal pallet system for interchangeable electronics. The machines received the designation OV-1G (for Germany) and were delivered in early 1980 via ship without any sensors or cameras. These were of Western German origin, developed and fitted locally, tailored to the special border surveillance needs.
The installation and testing of the “Schimmelreiter” ELINT suite lasted until 1982. It was based on a Raytheon TI Systems emitter locator system, but it was locally adapted by AEG-Telefunken to the airframe and the Bundeswehr’s special tasks and needs. The system’s hardware was stowed in the fuselage, its sensor arrays were mounted into a pair of underwing nacelles, which occupied the OV-1’s standard hardpoints, allowing a full 360° coverage. In order to cool the electronics suite and regulate the climate in the internal equipment bays, the OV-1G received a powerful heat exchanger, mounted under a wedge-shaped fairing on the spine in front of the tail – the most obvious difference of this type from its American brethren. The exact specifications of the “Schimmelreiter” ELINT suite remained classified, but special emphasis was placed upon COMINT (Communications Intelligence), a sub-category of signals intelligence that engages in dealing with messages or voice information derived from the interception of foreign communications. Even though the “Schimmelreiter” suite was the OV-1Gs’ primary reconnaissance tool, the whole system could be quickly de-installed for other sensor packs and reconnaissance tasks (even though this never happened), or augmented by single modules, what made upgrades and mission specialization easy. Beyond the ELINT suite, the OV-1G could be outfitted with cameras and other sensors on exchangeable pallets in the fuselage, too. This typically included a panoramic camera in a wedge-shaped ventral fairing, which would visually document the emitter sensors’ recordings.
A special feature of the German OV-1s was the integration of a brand new, NATO-compatible “Link-16” data link system via a MIDS-LVT (Multifunctional Information Distribution System). Even though this later became a standard for military systems, the OV-1G broke the ground for this innovative technology. The MIDS was an advanced command, control, communications, computing and intelligence (C4I) system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements. Outwardly, the MIDS was only recognizable through a shallow antenna blister behind the cockpit.
Even though the OV-1Gs initially retained their former American uniform olive drab livery upon delivery and outfitting in German service, they soon received a new wraparound camouflage for their dedicated low-level role in green and black (Luftwaffe Norm 83 standard), which was better suited for the European theatre of operations. In Luftwaffe service, the OV-1Gs received the tactical codes 18+01-05 and the small fleet was allocated to the Aufklärungsgeschwader (AG) 51 “Immelmann”, where the machines formed, beyond two squadrons with RF-4E Phantom IIs, an independent 3rd squadron. This small unit was from the start based as a detachment at Lechfeld, located in Bavaria/Southern Germany, instead of AG 51’s home airbase Bremgarten in South-Western Germany, because Lechfeld was closer to the type’s typical theatre of operations along Western Germany’s Eastern borders. Another factor in favor of this different airbase was the fact that Lechfeld was, beyond Tornado IDS fighter bombers, also the home of the Luftwaffe’s seven HFB 320M ECM aircraft, operated by the JaBoG32’s 3rd squadron, so that the local maintenance crews were familiar with complex electronics and aircraft systems, and the base’s security level was appropriate, too.
With the end of the Cold War in 1990, the OV-1Gs role and field of operation gradually shifted further eastwards. With the inner-German Iron Curtain gone, the machines were now frequently operated along the Polish and Czech Republic border, as well as in international airspace over the Baltic Sea, monitoring the radar activities along the coastlines and esp. the activities of Russian Navy ships that operated from Kaliningrad and Saint Petersburg. For these missions, the machines were frequently deployed to the “new” air bases Laage and Holzdorf in Eastern Germany.
In American service, the OV-1s were retired from Europe in 1992 and from operational U.S. Army service in 1996. In Germany, the OV-1 was kept in service for a considerably longer time – with little problems, since the OV-1 airframes had relatively few flying hours on their clocks. The Luftwaffe’s service level for the aircraft was high and spare parts remained easy to obtain from the USA, and there were still OV-1 parts in USAF storage in Western German bases.
The German HFB 320M fleet was retired between 1993 and 1994 and, in part, replaced by the Tornado ECR. At the same time AG 51 was dissolved and the OV-1Gs were nominally re-allocated to JaboG 32/3. With this unit the OV-1Gs remained operational until 2010, undergoing constant updates and equipment changes. For instance, the machines received in 1995 a powerful FLIR sensor in a small turret in the aircraft’s nose, which improved the aircraft’s all-weather reconnaissance capabilities and was intended to spot hidden radio posts even under all-weather/night conditions, once their signal was recognized and located. The aircrafts’ radio emitter locator system was updated several times, too, and, as a passive defensive measure against heat-guided air-to-air missiles/MANPADS, an IR jammer was added, extending the fuselage beyond the tail. These machines received the suffix “Phase II”, even though all five aircraft were updated the same way.
Reports that the OV-1Gs were furthermore retrofitted with the avionics to mount and launch AIM-9 Sidewinder AAMs under the wing tips for self-defense remained unconfirmed, even more so because no aircraft was ever seen carrying arms – neither the AIM-9 nor anything else. Plans to make the OV-1Gs capable of carrying the Luftwaffe’s AGM-65 Maverick never went beyond the drawing board, either. However, BOZ chaff/flare dispenser pods and Cerberus ECM pods were occasionally seen on the ventral pylons from 1998 onwards.
No OV-1G was lost during the type’s career in Luftwaffe service, and after the end of the airframes’ service life, all five German OV-1Gs were scrapped in 2011. There was, due to worsening budget restraints, no direct successor, even though the maritime surveillance duties were taken over by Dornier Do 228/NGs operated by the German Marineflieger (naval air arm).

The kit and its assembly:
This build became a submission to the “Reconnaissance” Group Build at whatifmodellers.com in July 2021, and it spins further real-world events. Germany actually tested two OV-1s in the Sixties (by the German Army/Bundesheer, not by the air force), but the type was not procured or operated. The test aircraft carried a glossy, olive drab livery (US standard, I think) with German national markings.
However, having a vintage Hasegawa OV-1A in the stash, I wondered what an operational German OV-1 might have looked like, especially if it had been operated into the Eighties and beyond, in the contemporary Norm 83 paint scheme? This led to this purely fictional OV-1G.
The kit was mostly built OOB, and the building experience was rather so-so – after all, it’s a pretty old mold/boxing (in my case the Hasegawa/Hales kit is from 1978, the mold is from 1968!). Just a few things were modified/added in order to tweak the standard, short-winged OV-1A into something more modern and sophisticated.
When searching for a solution to mount some ELINT sensor arrays, I did not want to copy the OV-1B’s characteristic offset, ventral SLAR fairing. I rather settled for the late RV-1D’s solution with sensor pods under the outer wings. Unfortunately, the OV-1A kit came with the type’s original short wings, so that the pods had to occupy the inner underwing pair of hardpoints. The pods were scratched from square styrene profiles and putty, so that they received a unique look. The Mohawk’s pair of ventral hardpoints were mounted, but – after considering some drop tanks or an ECM pod there - left empty, so that the field of view for the ventral panoramic camera would not be obscured.
Other small additions are some radar warning sensor bumps on the nose, some extra antennae, a shallow bulge for the MIDS antenna on the spine, the FLIR turret on the nose (with parts from an Italeri AH-1 and a Kangnam Yak-38!), and I added a tail stinger for a retrofitted (scratched) IR decoy device, inspired by the American AN/ALG-147. This once was a Matchbox SNEB unguided missile pod.
Painting and markings:
For the intended era, the German Norm 83 paint scheme, which is still in use today on several Luftwaffe types like the Transall, PAH-2 or CH-53, appeared like a natural choice. It’s a tri-color wraparound scheme, consisting of RAL 6003 (Olivgrün), FS 34097 (Forest Green) and RAL 7021 (Teerschwarz). The paints I used are Humbrol 86 (which is supposed to be a WWI version of RAL 6003, it lacks IMHO yellow but has good contrast to the other tones), Humbrol 116 and Revell 9. The pattern itself was adapted from the German Luftwaffe’s Dornier Do 28D “Skyservants” with Norm 83 camouflage, because of the type’s similar outlines.
A black ink washing was applied for light weathering, plus some post-shading of panels with lighter shades of the basic camouflage tones for a more plastic look. The cockpit interior was painted in light grey (Humbrol 167), while the landing gear and the interior of the air brakes became white. The scratched SLAR pods became light grey, with flat di-electric panels in medium grey (created with decal material).
The cockpit interior was painted in a rather light grey (Humbrol 167), the pilots received typical olive drab Luftwaffe overalls, one with a white “bone dome” and the other with a more modern light grey helmet.
The decals were improvised. National markings and tactical codes came from TL Modellbau sheets, the AG 51 emblems were taken from a Hasegawa RF-4E sheet. The black walkways were taken from the Mohak’s OOB sheet, the black de-icer leading edges on wings and tail were created with generic black decal material. Finally, the model was sealed with a coat of matt acrylic varnish (Italeri).
An interesting result, and the hybrid paint scheme with the additional desert camouflage really makes the aircraft an unusual sight, adding to its credibility.

Some background:
The APS-4 was a light-weight, pod-mounted airborne search Radar which was suitable for either Airborne Interception (AI) or Air-to-Surface-Vessel (ASV) applications. It was a member of a series of early air-borne radar equipment and was initially designated as AS-H (“Air-to Surface, version H”). This very advanced equipment for its time was first used by the US Navy on board of carrier-borne night fighter aircraft like respective F6F Hellcat and F4U-2 Corsair variants. The Royal Air Force was impressed enough with the system's performance that it was adopted in 1943 for domestic airframes, too, as an alternative to the British AI radars used on board of early Mosquito, Beaufighter and Defiant night fighters.
One very successful carrier of the APS-4, in RAF service known as the AI Mk XV, was the De Havilland Mosquito in its NF Mk.XIX and NF Mk.30 night fighter incarnations. Aware of the performance and effectiveness of the American single engine aircraft, though, the RAF decided to test similar domestic airframes towards the end of WWII as well. The shorter range of a single engine night fighter would, compared with the bigger but also more sluggish two engine types, be compensated by higher speed, agility and rate of climb. These lighter aircraft were intended as a second defense for homeland defense, esp. around large cities or industrial sites.
One of these projects concerned the Supermarine Spitfire, more specifically the new types powered by a Rolly Royce Griffon engine. The Griffon provided a substantial performance increase over the Merlin-powered Spitfire Mk IX, but initially suffered from poor high altitude performance due to having only a single stage supercharged engine. By 1943, Rolls-Royce engineers had developed a new Griffon engine, the 61 series, with a two-stage supercharger, leading to a slightly modified engine, the 65 series, which was eventually mounted in the Spitfire Mk XIV.
With this performance surplus, a night fighter, despite carrying the AI Mk XV equipment plus a second crew member, was still expected to offer a superior performance over German two-engine bombers that intruded British airspace and the heavy night fighters that lurked over the Channel and attacked grouping RAF night bomber formations before they entered Continental airspace.
From this idea, the Spitfire NF.XX was born, as an alternative to a Hawker Typhoon night fighter with a British radar and only a single crew member. In summer 1944 an initial prototype was built, converted from an early series production Mk. XIV airframe. Since the AI Mk XV came with a rather complicated and voluminous display, a second crew member was deemed necessary for effective operations, esp. at night and under poor visibility conditions. The radio operator would check the radar readings and verbally guide the pilot towards the target, who could concentrate on the flying job and keep the eyes on the surroundings.
In order to fit the equipment and the second crew member into the tight Spitfire airframe, and a separate compartment behind the pilot's cockpit and the real bulkhead was added. This second seat received a separate sliding canopy, resulting in a distinctive camel hump silhouette, which earned the Spitfire NF.XX quickly the nickname 'Camelback'. Supermarine had proposed a new service name for this aircraft, 'Nightfire', but it was not officially accepted, since the machine did not differ enough from the basic Spitfire day fighter to justify a completely new designation.
The AI Mk XV equipment and its antenna were carried in a bullet-shaped pod under the port wing, similar to the US Navy night fighters’ arrangement. The radar dish was designed to scan from side to side for AI applications, but it could also be commanded to look up and down by a few degrees. This enabled the aircraft to attack targets from above, and it could also search for surface vessels below, so that the aircraft could also act in ASV or pathfinder duties in a secondary role (much like the Mosquito night fighters, which frequently guided bomber formations to their targets).
In order to mount the pod to the outer wing and compensate for the gain of weight, the standard 0.303" Browning machine guns normally located there were deleted. Instead, the NF.XX was initially armed with two 20 mm Hispano cannon plus a pair of 0.5" machine guns, mounted in a fashion similar to the Spitfire's standard E wing.
The NF.XX was powered, like the Spitfire Mk. XIV, by the two-stage supercharged Griffon 65, producing 2,050 hp (1,528 kW). A five bladed Rotol propeller of 10 ft 5 in (3.18 m) in diameter was used, and for the night fighter role the standard single exhaust stubs gave way to a collector fairing on each side, which dampened flames and improved the crew's view in the darkness.
To help balance the heavy Griffon engine, the radio equipment was moved further back in the rear fuselage. Improved VHF radio equipment allowed for the aerial mast to be removed and replaced by a "whip" aerial further aft on the fuselage spine. Because of the longer nose and the increased slipstream of the big five-bladed propeller, a new tail unit, with a taller, broader fin and a rudder of increased area was introduced.
One problem that hampered all early Griffon-powered Spitfire variants also plagued the NF.XX, though: short legs. The NF.XX carried a total of 109.5 gal of fuel, consisting of 84 gal in two main tanks and a 12.5 imp gal fuel tank in each leading edge wing tank. With this internal capacity, the fighter's maximum range was just a little over 460 miles (740 km) since the new Griffon engine consumed much more fuel per hour than the Merlin engine of earlier variants, and the extra drag and weight through the radar equipment did not make things better.
As a simple remedy, a conformal, fixed belly tank between the radiators was devised. This carried an extra 90 gal, of fuel, extending the fighter's range to about 850 miles (1,370 km) – still not much for aerial patrol and extended loiter time for interceptions, but enough for short-notice home defense duties. Alternatively, a more conventional but jettisonable 100 gal. drop tank could be carried, but it produced considerably more drag and affected overall performance so dramatically that it was never used in service.
The first tests of the new aircraft were conducted in January 1945 and three pre-production machines (all converted Mk. XIV airframes) were allocated to night fighter units for field trials and direct comparison with two engine types. Despite its innate aerodynamic and weight penalties the Spitfire NF.XX still attained an impressive top speed of 400 mph (350 kn; 640 km/h) at 29,500 ft (9.000 m), even though in clean condition only. But it was still more than enough to take on much heavier German bombers and night fighters. The second crewman was another winning factor, since the pilot alone would be overloaded in the face of heavily armed enemy aircraft in the European theatre of operations and the local weather conditions.
Further initial experience with the type resulted in several ad hoc modifications: the wing span was increased in order to improve handling and climb performance, using standard wing tip extensions from Spitfire high altitude variants. Furthermore, a deeper rudder was added to the fin because the second cockpit created significant directional instability.
Armament was changed, too - more firepower and a longer range was deemed necessary to attack the German heavy night fighters, which themselves frequently carried defensive armament in the form of heavy machine guns. Consequently, the initial pair of 0.5" machine guns was deleted and replaced by an additional pair of 20 mm Hispano cannon, and all four guns received extended barrels for a higher weapon range.
In this form, the Spitfire NF.XX quickly entered RAF service in March 1945, but, in the meantime, the German night fighter threat had declined, so that only 50 machines were completed and delivered to RAF units in the UK until the end of hostilities.
The operational use of the machines was hampered by localized skin wrinkling on the wings and fuselage at load attachment points, a problem the type shared with the Mk. XIV day fighter. Even though Supermarine advised that the machines had not been seriously weakened, nor were they on the point of failure, the RAF nevertheless issued instructions in early 1945 that all F and FR Mk XIVs were to be retrospectively fitted with clipped wings to counter the threat. The NF.XX kept their elongated wing tips, however, and were simply limited to a top speed of 370 mph (600 km/h) and not allowed to dive anymore.

The kit and its assembly:
Well, Spitfire fans might call it crude to create a whiffy variant that incorporates so many ugly details. But this fever creation came into being through the simple thought: "What would a dedicated Spitfire night fighter with a radar look like?" From this initial creative spark I tried to build this fictional NF.XX variant with available late WWII technology from a Griffon-powered Spitfire.
The basis is the Airfix Spitfire PR.XIX kit, a nice and clean offering, even though the use of this photo recce variant meant some additional work. The radar pod comes wholesale from an F4U night fighter (Fujimi), since the wing installation appeared to me to be the only plausible (and proven) option.
The second cockpit and the "double bubble" canopy come from an RS Models Spitfire Mk.IX UTI trainer, which is/was a domestic conversion made in the Soviet Union. The kit comes with an extra two seater fuselage, so that, despite body donors, almost a complete Spitfire remains (just the cockpit missing, but this can be taken from the Airfix kit).
I also considered the Spitfire TR.IX arrangement, with a stepped bubble canopy, but found that the risen rear cockpit for the instructor would not make sense in a night fighter, so the UTI arrangement with separate canopies on the same level appeared to me to be the most suitable solution for this aircraft and its task.
Surgery was not easy, though: The whole cockpit area was dissected from the RS Models trainer and – together with the internal parts like the bulkheads, dashboards and seats – transplanted into an appropriate gap, cut into the Airfix kit fuselage. The windscreen position on both airframes was used as orientation benchmark.
Basically a simple idea, but, even though you have two Spitfire kits at hand, both models differ slightly from each other in many ways. Material thickness is different, as well as panel lines, which are all there on both models but simply do not fall in line. Internal width and available space is also different, esp. the rear bulkhead was not easy to integrate into the Airfix fuselage. It worked, somehow, but it consequently took some PSR effort and rescribing (at least, both donor kits have engraved details) in order to create this Griffon-powered two-seater.
The extended wings were created through the simple implantation of high altitude wing tips from an AZ Model Spitfire I/II/V/VI kit. They match very well with the Airfix PR.XIX wings, which were simply clipped at the correct position outside of the ailerons. Since the recce Spitfire comes without any weapons I added four brass barrels (Pavla) to the wings, plus respective bulges for the magazines (scratched from sprue) and casing ejector fairings under the wings.
I also changed the vertical rudder. Instead of the separate OOB part from the Spitfire PR.XIX I used a deeper and higher rudder from a late Seafire mark (left over from a Special Hobby kit, IIRC). The part lost its hook and the notch for its deployment mechanism, replaced by a piece of styrene that was PSRed into the rest of the rudder. It’s not an obvious change, but the bigger fin area is a good counterpart to the enlarged wings and the bulkier rear fuselage.
The conformal belly tank was scratched from the upper half of a Matchbox A-10 inner wing. There are aftermarket solutions available, but I simply did not want to spend as much money on a single resin part that no one will clearly see and that’s just as expensive as the whole Airfix basis kit. Some things are just ridiculous.
Painting and markings:
Very simple: classic late war RAF night fighter colors, with Medium Sea Grey and Dark Green (Humbrol 165 and 163, respectively) on the uppers surfaces, plus Night (I used Revell Acrylics 06, Tar Black, which is actually a very dark grey tone) underneath, with a high waterline and a black fin. Looks weird on a Spitfire, but also somewhat cool!? The model received a light black ink wash and some panel post-shading, using a blue-ish hue for the Night undersurfaces.
The interior is classic RAF Cockpit Green (Humbrol 78), the only catchy marking is the red propeller spinner – originally I just wanted to keep the spinner black, too, but found that to be too dull overall.
The markings come from different sources; the codes were created with single Dull Red letters from Xtradecal, roundels and other markings come from various other sheets. The added “G” to the serial number is, BTW, an indication that the aircraft had to be guarded all the time. A nice and appropriate detail for this high tech aircraft of its time. The roundels/fin flashes were taken from another Xtradecal sheet, IIRC they belong to an FAA SB2C Helldiver.
Finally, some wear marks were added with dry-brushed light grey and silver. Exhaust stains were added with dry-brushed dark and light grey, as well as some grinded graphite. A coat of matt acrylic varnish (Italeri) sealed the kit.
I feel a bit guilty of creating the probably ugliest Spitfire possible, with all the add-ons and the weird proportions through the second cockpit and the belly tank. Very massive, at least for this sleek aircraft. The night fighter paint scheme suits the Spitfire surprisingly well, though. Anyway, it’s whifworld, after all, and I tried to go through with the night fighter idea as good and consequential as possible – the fictional NF.XX is just my personal interpretation of the theme.

Some background:
The APS-4 was a light-weight, pod-mounted airborne search Radar which was suitable for either Airborne Interception (AI) or Air-to-Surface-Vessel (ASV) applications. It was a member of a series of early air-borne radar equipment and was initially designated as AS-H (“Air-to Surface, version H”). This very advanced equipment for its time was first used by the US Navy on board of carrier-borne night fighter aircraft like respective F6F Hellcat and F4U-2 Corsair variants. The Royal Air Force was impressed enough with the system's performance that it was adopted in 1943 for domestic airframes, too, as an alternative to the British AI radars used on board of early Mosquito, Beaufighter and Defiant night fighters.
One very successful carrier of the APS-4, in RAF service known as the AI Mk XV, was the De Havilland Mosquito in its NF Mk.XIX and NF Mk.30 night fighter incarnations. Aware of the performance and effectiveness of the American single engine aircraft, though, the RAF decided to test similar domestic airframes towards the end of WWII as well. The shorter range of a single engine night fighter would, compared with the bigger but also more sluggish two engine types, be compensated by higher speed, agility and rate of climb. These lighter aircraft were intended as a second defense for homeland defense, esp. around large cities or industrial sites.
One of these projects concerned the Supermarine Spitfire, more specifically the new types powered by a Rolly Royce Griffon engine. The Griffon provided a substantial performance increase over the Merlin-powered Spitfire Mk IX, but initially suffered from poor high altitude performance due to having only a single stage supercharged engine. By 1943, Rolls-Royce engineers had developed a new Griffon engine, the 61 series, with a two-stage supercharger, leading to a slightly modified engine, the 65 series, which was eventually mounted in the Spitfire Mk XIV.
With this performance surplus, a night fighter, despite carrying the AI Mk XV equipment plus a second crew member, was still expected to offer a superior performance over German two-engine bombers that intruded British airspace and the heavy night fighters that lurked over the Channel and attacked grouping RAF night bomber formations before they entered Continental airspace.
From this idea, the Spitfire NF.XX was born, as an alternative to a Hawker Typhoon night fighter with a British radar and only a single crew member. In summer 1944 an initial prototype was built, converted from an early series production Mk. XIV airframe. Since the AI Mk XV came with a rather complicated and voluminous display, a second crew member was deemed necessary for effective operations, esp. at night and under poor visibility conditions. The radio operator would check the radar readings and verbally guide the pilot towards the target, who could concentrate on the flying job and keep the eyes on the surroundings.
In order to fit the equipment and the second crew member into the tight Spitfire airframe, and a separate compartment behind the pilot's cockpit and the real bulkhead was added. This second seat received a separate sliding canopy, resulting in a distinctive camel hump silhouette, which earned the Spitfire NF.XX quickly the nickname 'Camelback'. Supermarine had proposed a new service name for this aircraft, 'Nightfire', but it was not officially accepted, since the machine did not differ enough from the basic Spitfire day fighter to justify a completely new designation.
The AI Mk XV equipment and its antenna were carried in a bullet-shaped pod under the port wing, similar to the US Navy night fighters’ arrangement. The radar dish was designed to scan from side to side for AI applications, but it could also be commanded to look up and down by a few degrees. This enabled the aircraft to attack targets from above, and it could also search for surface vessels below, so that the aircraft could also act in ASV or pathfinder duties in a secondary role (much like the Mosquito night fighters, which frequently guided bomber formations to their targets).
In order to mount the pod to the outer wing and compensate for the gain of weight, the standard 0.303" Browning machine guns normally located there were deleted. Instead, the NF.XX was initially armed with two 20 mm Hispano cannon plus a pair of 0.5" machine guns, mounted in a fashion similar to the Spitfire's standard E wing.

Star Hawk Vx
Less than three lunar months after the mysterious disappearence of Unitron system's Star Hawk V test prototype, sightings were reported of a Galaxy Patrol that bore a striking resemblance to the missing craft.
Galaxy Patrol Engineering and Weapons Division added upgraded proton fusion gravity drive engines designed for a much larger craft, making the Vx capable of achieving incredible speeds and distances. Unitron surveillance gear was scrapped in favor of twin triple-barrel plasma cannons and photon missile batteries.
The Vx also displays the Galaxy Patrol’s dark blue and orange livery and characteristic bling.
Unitron system representatives deny any link to their missing craft.
With the lightweight aluminium front and rear axles from the BMW M3/M4 models, forged 19-inch aluminium wheels with mixed-size tyres, M Servotronic steering with two settings and suitably effective M compound brakes, the new BMW M2 Coupe has raised the bar once again in the compact high-performance sports car segment when it comes to driving dynamics. The electronically controlled Active M Differential, which optimises traction and directional stability, also plays a significant role here. And even greater driving pleasure is on the cards when the Dynamic Stability Control system’s M Dynamic Mode (MDM) is activated. MDM allows wheel slip and therefore moderate, controlled drifts on the track.

Some background:
When, towards late 1945, the Einheits-Chassis for the German combat tanks (the "E" series of medium and heavy tanks) reached the front lines, several heavily armed anti-aircraft turrets had been developed, including the 30mm Kugelblitz, based on the outdated Panzer IV, the "Coelian" turret with various armament options for the Panzer V Panther hull, and there were twin 55 mm as well as single and even 88mm cannon systems for the new E-50, E-75 and E-100 chassis'.
With these new weapons for medium- and high-altitude targets, Firepower was considerably increased, but the tank crews still had to rely on traditional visual tracking and aiming of targets. One potential solution in which the German Heeresleitung was highly interested from the start was the use of the Luftwaffe’s new radar technology for early target identification and as an aiming aid in poor weather conditions or even at night. The German Luftwaffe first introduced an airborne interception radar in 1942, but these systems were bulky and relied upon large bipolar antenna arrays. These were not suitable for any use in a ground vehicle, lest to say in a tank that would also carry weapons and ammunition.
A potential solution appeared in late 1944 with the development of the FuG 240 "Berlin". It was an airborne interception radar, too, but it was the first German radar to be based on the cavity magnetron, which eliminated the need for the large multiple dipole-based antenna arrays seen on earlier radars, thereby greatly increasing the performance of the night fighters. The FuG 240 with a rotating dish antenna was introduced by Telefunken in April 1945, primarily in Junkers Ju 88G-6 night-fighters, behind a plywood radome which considerably improved aerodynamics. This so greatly reduced drag compared to the late-model Lichtenstein and Neptun systems that the fighters regained their pre-radar speeds and made them competitive again. The FuG 240 was effective against bomber-sized targets at distances of up to 9 kilometers (5.5 mi), or down to 0.5 kilometer, which eliminated the need for a second, short-range radar system.
Right before the FuG 240's roll-out with the Luftwaffe, the Heer insisted on a ground-based derivative for its anti-aircraft units. Political pressure from Berlin convinced the RLM to share the new technology, and Telefunken was ushered to adapt the radar system to an armored ground vehicle in February 1945.
It soon became clear that the FuG 240 had several drawbacks for this task. On one side, ground clutter and the natural horizon limited the system's range and low-level effectiveness, but its 9 km range in free space made high altitude surveillance possible – just enough for the effective interception of Allied bombers that attacked important point targets. Furthermore, the whole system, together with its power supply and a dirigible dish antenna, took up a lot of space, so that its integration into a tank-based anti-aircraft vehicle like an SPAAG as an autonomous, stand-alone solution was ruled out.
A workable solution eventually came as a technical and tactical compromise: the army’s anti-aircraft tanks were to be grouped together in so-called Panzer-Fla-Züge, which consisted of several (typically four) SPAAGs and an additional, dedicated radar surveillance and command unit, so that the radar could guide the tank crews towards incoming targets – even though the gun crews still had to rely on visual targeting.
Two respective guidance vehicles developed, a light and a heavy one. The light one, intended against low-flying targets like the Ilyushin Il-2 on the Eastern front, became the 8x8 Funkmess-/Flak-Kommandowagen Sd.Kfz. 234/6. The heavy variant, with a bigger antenna and a more powerful emitter, became the Mittlerer Funkmess-/Flak-Kommandopanzer Sd.Kfz. 282. In contrast to the light and compact Sd.Kfz. 234/6, the Sd.Kfz. 282’s complete radar and observation system was installed in a new turret, so that it could be simply mounted onto the new E-50 Einheitspanzer battle tank hull.
This new, box-shaped turret had been developed by Rheinmetall, together with Telefunken, and was based on the turret design for the new 55 mm twin anti-aircraft cannon. It had a maximum armor of 60mm at the front and held all of the radar equipment, christened "Basilisk", after the monster from medieval mythology with a petrifying sight. The turret held a crew of three: a commander, a radar operator, and an observer for the optical rangefinder. The rest of the crew, the driver and a radio operator, sat in the hull. No armament was fitted, even though a light machine gun could be mounted on the roof for self-defense, even though it could not be operated from the inside. A heavier armament was not deemed necessary since the vehicle would stay close to the heavily armed tanks/SPAAGs it would typically accompany.
The Basilisk radar’s rotating dish antenna had a diameter of 90 cm (35 ½ inches) and was installed at the turret's front under a hard vinyl cover. Power of the modified FuG 240 was 25kW, with a search angle of +80/− 5° and a frequency range: 3,250–3,330MHz (~10 cm). Range was, due the bigger antenna and a higher emitter output, increased to 0.5–11.0 kilometer, even though only under ideal conditions. Power came from a dedicated generator that was connected to the E-50’s V-12 Maybach HL 234 gasoline engine.
Beyond the radar system, the vehicle was furthermore equipped with a powerful visual coincidence range finder in the turret, combined with an analogue computer, the Kommandogerät (KDO) 40 Telemeter. This system had been introduced in 1941 as a guidance tool for stationary anti-aircraft units equipped with the 88 mm and the 105 mm Flak, but it had so far – due to its size and bulk – only been deployed on an unarmored trailer
The KDO 40 and similar sights worked as follows: Light from the target entered the range finder through two windows located at either end of the instrument. At either side, the incident beam was reflected to the center of the optical bar by a pentaprism, and this optical bar was ideally made from a material with a low coefficient of thermal expansion so that optical path lengths would not change significantly with temperature. The reflected beam first passed through an objective lens and was then merged with the beam of the opposing side with an ocular prism sub-assembly to form two images of the target which were viewed by the observer through the eyepiece. Since either beam entered the instrument at a slightly different angle the resulting image, if unaltered, would appear blurry. Therefore, in one arm of the instrument, a compensator was integrated which could be adjusted by the operator to tilt the beam until the two images matched. At this point, the images were said to be in coincidence. The degree of rotation of the compensator determined the range to the target by simple triangulation, allowing the calculation of the distance to the observed object.
Fixed target reading with the device mounted in the Sd.Kfz. 282 turret was possible on targets from 3,000 to 20,000 m. Aerial courses could be recorded at all levels of flight and at a slant range between 4,000 and 18,000 m - enough for visual identification beyond an anti-aircraft group's effective gun ranges and perfectly suitable for long range observation, so that the Sd.Kfz. 282 also had excellent reconnaissance and observation capabilities. The rangefinder’s optical bar had a massive span of 400 cm (157.5 in) and went right through the turret, just above the radar device installation. The whole device, together with its armored fairing, was 4,60 m (15 ft 1 in) wide, so that it protruded from the turret on both sides over the lower hull. The odd and unwieldy installation quickly earned the vehicle nicknames like "Hirsch (stag)", "Zwo-Ender" (a young stag with just two antlers) or “Ameise” (ant). None of these were official, though. In order to protect the Telemeter on the way, the turret was normally turned by 90° and hidden under a tarpaulin, in order not to give away any details of the highly classified equipment.
However, development of the Einheitspanzer family lagged behind schedule, and in early 1945 no E-50 chassis was available for the highly specialized Sd.Kfz. 282 – battle tanks and SPGs were in higher demand. As an alternative, the turret was quickly adapted for different tank hulls, namely the Sd.Kfz. 171, the Panzer V ‘Panther’ medium tank and the heavy Sd.Kfz. 181 ‘Tiger I’. Tests with both hulls in spring 1945 were successful, but only the lighter ‘Panther’ hull was chosen because it was lighter overall, more mobile and available in sufficient numbers for a quick roll-out. In this configuration, the system received the designation Sd.Kfz. 282/1, while the original Sd.Kfz. 282 designation was reserved for the originally planned E-50 chassis variant.
The first vehicles reached, together with the new FlaK tanks, the front units in September 1945. Operating independently, they were primarily allocated to the defense of important production sites and the city of Berlin, and they supported tank divisions through early warning duties and visual long-range reconnaissance. Operationally, the Sd.Kfz. 282’s sensor setup with its combined visual and radar input turned out to be surprisingly successful. The combination of the Basilisk radar with the KDO 40 rangefinder allowed a time from initial target acquisition to the first AA shot of less than 20 seconds, which was impressive for the time – typically, simple visual target acquisition took 30 seconds or more. First shot hit probability was appreciably improved, too, and even quick passes of aircraft at low altitudes could be precalculated, if the radar was not obstructed.
However, the radar remained capricious, its performance rather limited and the unarmored antenna fairing at the turret’s front was easily damaged in combat, even by heavy machinegun fire. But the Sd.Kfz. 282 offered, when the vehicle was placed in a location with a relatively free field of view (e. g. on a wide forest clearance or in an open field), a sufficient early warning performance against incoming bombers at medium to high altitudes, and it also appreciably mobilized the bulky but valuable KDO 40 device. It now could easily be moved around and keep up with the pace of motorized battle groups that the Panzer-Fla-Züge units were supposed to protect.
Until the end of hostilities, probably thirty Sd.Kfz. 282/1s were completed from newly built (Ausf. F, recognizable through the simpler all-metal wheels) or from refurbished earlier Panzer V chassis of various types before production switched in early 1946 to the E-50 chassis which had eventually become available in sufficient numbers.

The kit and its assembly:
Another submission to the “Recce & Surveillance” group build at whatifmodellers.com in July 2021, and actually a good occasion to tackle a project that I had on my list for some years. A long while ago I bought a resin conversion set with a (purely fictional) Heer ‘46 anti-aircraft surveillance radar system, based on an E-50 chassis. Unfortunately, I cannot identify the manufacturer, but this 1:72 conversion set was/is nicely molded, with delicate details, no bubbles or flash and it even came with a commander figure for an optional open hatch on top as well as a pair of delicate brass antennae.
Even though I could have mounted this replacement turret onto a Trumpeter or Modelcollect E-50/75 chassis, I rather decided to create an earlier (1945 time frame) interim vehicle on a late Panzer V ‘Panther’ basis, mostly because it would be more compact and I doubt that brand new E-50/75s would have been “wasted” on second line/support vehicles like this mobile surveillance/commando post for anti-aircraft units?
The Panther chassis is the old Hasegawa kit for an Ausf. G tank from 1973, chosen because of its good fit, simplicity and the vinyl tracks, which I prefer. However, the kit clearly shows its age and some weak/soft details (e. g. the gratings on the engine deck), but it was enough for my plans and easy to handle.
Both turret and hull were built separately and basically OOB, combined with an adjusted turret ring. The Kdo 40’s “antlers” are to be glued directly to the turret’s flanks, but I reinforced the connections with wire. I also replaced the set’s brass antennae with heated sprue material and used a surplus PE detail set from a Modelcollect E-50/75 to hide the crude engine openings and change the overall look of the Panther a little. Some storage boxes as well as spare track links were added to the flanks, stuff collected from the scrap box.
To emphasize the refurbished character of the vehicle I left away the Panther’s side skirts – these were easily lost in battle, anyway, and probably have rather been allocated to battle tanks than to 2nd line support vehicles, despite leaving the Panther’s lower hull under the mudguards vulnerable.
Painting and markings:
Even though the paint scheme on this model is based on German standard colors, it is a little special. Late in real-world WWII some Panzer Vs received a unique, uniform RAL 6003 (Olivgrün) factory finish instead of the usual all-over RAL 7028 (Dunkelgelb) or the bare oxide red primer finish, onto which the frontline units would add individual camouflage, depending on the theatre of operations and whatever paint or application tool was at hand. This special green livery was adopted for the model, including the new turret. The individual camouflage consists of diagonal stripes in Dunkelgelb and Rotbraun (RAL 8017), added on top of the green basis with rather sharp and straight edges and only to the vertical surfaces. The practice to leave out the horizontal surfaces was called “Sparanstrich” (literally “economy paintwork”), an attempt to save the more and more scarce paint.
This rather odd style was actually applied to several late war Panther tanks – even though I am personally not certain about this pattern’s effectiveness? Maybe a kind of dazzle effect was sought for?
The basic green became a modern-day RAL 6003 from the rattle can (which is very close to FS 34102, just a tad lighter), applied in a rather cloudy fashion on top of an initial coat of Oxide Red primer (RAL 3009) overall, also from the rattle can. On top of that the stripes were painted with a brush, partly masked but mostly free-handedly. For some variation I used this time Tamiya XF-60 (a rather pale interpretation of Dunkelgelb which IMHO lacks a greenish hue and rather looks like a desert sand tone) and XF-64 (a rich whole milk chocolate tone) to create the additional camouflage, not fully opaque so that the impression of thinly/hastily applied paint was reinforced.
Once dry, the whole surface received a very dark brown washing with thinned acrylic paint and surface details were emphasized through dry-brushing with earth brown and beige.
For a different look (and to break up the tank’s bulky outlines) I applied camouflage nets to the model, realized with gauze bandages drenched in Tamyia XF-62 (Olive Drab) and mounted into place around the turret and at the front of the hull while still slightly wet.
Decals were puzzled together from various German tank sheets. The kit was sealed with matt acrylic varnish, what also fixed the cammo nets in place. The originally shiny black vinyl tracks were also painted/weathered, with a wet-in-wet mix of grey, iron, black and red brown (all acrylics). Once mounted into place, mud and dust were simulated around the running gear and the lower hull with a greyish-brown mix of artist mineral pigments.
Not a spectacular build, but I am happy that I eventually had the opportunity and motivation to tackle this project that had been lingering for years in the The Stash™. The result looks really good – the anonymous resin set is/was excellent, and combined with the Panther hull, the whole thing looks very credible. I am only a bit sad that the odd, almost artistic camouflage got a little lost under the cammo nets and the equipment on the hull, and the dust/dirt on the lower areas blurs the three basic colors even more. Well, you cannot have everything at once, and I might re-use this scheme on a “cleaner” future build.
+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
When, towards late 1945, the Einheits-Chassis for the German combat tanks (the "E" series of medium and heavy tanks) reached the front lines, several heavily armed anti-aircraft turrets had been developed, including the 30mm Kugelblitz, based on the outdated Panzer IV, the "Coelian" turret with various armament options for the Panzer V Panther hull, and there were twin 55 mm as well as single and even 88mm cannon systems for the new E-50, E-75 and E-100 chassis'.
With these new weapons for medium- and high-altitude targets, Firepower was considerably increased, but the tank crews still had to rely on traditional visual tracking and aiming of targets. One potential solution in which the German Heeresleitung was highly interested from the start was the use of the Luftwaffe’s new radar technology for early target identification and as an aiming aid in poor weather conditions or even at night. The German Luftwaffe first introduced an airborne interception radar in 1942, but these systems were bulky and relied upon large bipolar antenna arrays. These were not suitable for any use in a ground vehicle, lest to say in a tank that would also carry weapons and ammunition.
A potential solution appeared in late 1944 with the development of the FuG 240 "Berlin". It was an airborne interception radar, too, but it was the first German radar to be based on the cavity magnetron, which eliminated the need for the large multiple dipole-based antenna arrays seen on earlier radars, thereby greatly increasing the performance of the night fighters. The FuG 240 with a rotating dish antenna was introduced by Telefunken in April 1945, primarily in Junkers Ju 88G-6 night-fighters, behind a plywood radome which considerably improved aerodynamics. This so greatly reduced drag compared to the late-model Lichtenstein and Neptun systems that the fighters regained their pre-radar speeds and made them competitive again. The FuG 240 was effective against bomber-sized targets at distances of up to 9 kilometers (5.5 mi), or down to 0.5 kilometer, which eliminated the need for a second, short-range radar system.
Right before the FuG 240's roll-out with the Luftwaffe, the Heer insisted on a ground-based derivative for its anti-aircraft units. Political pressure from Berlin convinced the RLM to share the new technology, and Telefunken was ushered to adapt the radar system to an armored ground vehicle in February 1945.
It soon became clear that the FuG 240 had several drawbacks for this task. On one side, ground clutter and the natural horizon limited the system's range and low-level effectiveness, but its 9 km range in free space made high altitude surveillance possible – just enough for the effective interception of Allied bombers that attacked important point targets. Furthermore, the whole system, together with its power supply and a dirigible dish antenna, took up a lot of space, so that its integration into a tank-based anti-aircraft vehicle like an SPAAG as an autonomous, stand-alone solution was ruled out.
A workable solution eventually came as a technical and tactical compromise: the army’s anti-aircraft tanks were to be grouped together in so-called Panzer-Fla-Züge, which consisted of several (typically four) SPAAGs and an additional, dedicated radar surveillance and command unit, so that the radar could guide the tank crews towards incoming targets – even though the gun crews still had to rely on visual targeting.
Two respective guidance vehicles developed, a light and a heavy one. The light one, intended against low-flying targets like the Ilyushin Il-2 on the Eastern front, became the 8x8 Funkmess-/Flak-Kommandowagen Sd.Kfz. 234/6. The heavy variant, with a bigger antenna and a more powerful emitter, became the Mittlerer Funkmess-/Flak-Kommandopanzer Sd.Kfz. 282. In contrast to the light and compact Sd.Kfz. 234/6, the Sd.Kfz. 282’s complete radar and observation system was installed in a new turret, so that it could be simply mounted onto the new E-50 Einheitspanzer battle tank hull.

This system had been introduced in 1941 as a guidance tool for stationary anti-aircraft units equipped with the 88 mm and the 105 mm Flak, but it had so far – due to its size and bulk – only been deployed on an unarmored trailer
The KDO 40 and similar sights worked as follows: Light from the target entered the range finder through two windows located at either end of the instrument. At either side, the incident beam was reflected to the center of the optical bar by a pentaprism, and this optical bar was ideally made from a material with a low coefficient of thermal expansion so that optical path lengths would not change significantly with temperature.

The University of Arizona (also referred to as UA, U of A, or Arizona) is a land-grant and space-grant public institution of higher education and research located in Tucson, Arizona, United States. The University of Arizona was the first university in the state of Arizona, founded in 1885 (twenty-seven years before the Arizona Territory achieved statehood), and is considered a Public Ivy. UA includes the only medical school in Arizona that grants M.D. degrees. In 2006, total enrollment was 36,805 students. UA is governed by the Arizona Board of Regents.
The University of Arizona was approved by the Arizona Territory''''''''''''''''s Thieving Thirteenth Legislature in 1885. The city of Tucson had hoped to receive the appropriation for the territory''''''''''''''''s mental hospital, which carried a $100,000 allocation instead of the $25,000 allotted to the territory''''''''''''''''s only university (Arizona State University was also chartered in 1885, but at the time it was created as Arizona''''''''''''''''s normal school, and not a university). Tucson''''''''''''''''s contingent of legislators was delayed in reaching Prescott due to flooding on the Salt River and by the time they arrived back-room deals allocating the most desirable territorial institutions had already been made. Tucson was largely disappointed at receiving what was viewed as an inferior prize. With no parties willing to step forth and provide land for the new institution, the citizens of Tucson prepared to return the money to the Territorial Legislature until two gamblers and a saloon keeper decided to donate the land necessary to build the school. Classes met for the first time in 1891 with 32 students in Old Main, the first building constructed on campus, and still in use to this day.[2]
Because there were no high schools in Arizona Territory, the University maintained separate preparatory classes for the first 23 years of operation.
The main campus sits on 380 acres (1.5 km2) in central Tucson, about one mile (1.6 km) northeast of downtown. There are 179 buildings on the main campus. Many of the early buildings, including the Arizona State Museum buildings (one of them the 1927 main library) and Centennial Hall, were designed by Roy Place, a prominent Tucson architect. It was Place''''''''''''''''s use of red brick that set the tone for the red brick facades that are a basic and ubiquitous part of nearly all UA buildings, even those built in recent decades. Indeed, almost every UA building has red brick as a major component of the design, or at the very least, a stylistic accent to harmonize it with the other buildings on campus. [3][4]
The campus is roughly divided into quadrants. The north and south sides of campus are delineated by a grassy expanse called the Mall, which stretches from Old Main eastward to the campus'''''''''''''''' eastern border at Campbell Avenue (a major north-south arterial street). The west and east sides of campus are separated roughly by Highland Avenue and the Student Union Memorial Center (see below).
The science and mathematics buildings tend to be clustered in the southwest quadrant; the intercollegiate athletics facilities to the southeast; the arts and humanities buildings to the northwest (with the dance department being a major exception as its main facilities are far to the east end of campus), with the engineering buildings in the north central area. The optical and space sciences buildings are clustered on the east side of campus near the sports stadiums and the (1976) main library.
Speedway Boulevard, one of Tucson''''''''''''''''s primary east-west arterial streets, traditionally defined the northern boundary of campus but since the 1980s, several university buildings have been constructed north of this street, expanding into a neighborhood traditionally filled with apartment complexes and single-family homes. The University has purchased a handful of these apartment complexes for student housing in recent years. Sixth Street typically defines the southern boundary, with single-family homes (many of which are rented out to students) south of this street.
Park Avenue has traditionally defined the western boundary of campus, and there is a stone wall which runs along a large portion of the east side of the street, leading to the old Main Gate, and into the driveway leading to Old Main.
Along or adjacent to all of these major streets are a wide variety of retail facilities serving the student, faculty and staff population: shops, bookstores, bars, banks, credit unions, coffeehouses and major chain fast-food restaurants such as Burger King and Chick-fil-A. The area near University Boulevard and Park Avenue, near the Main Gate, has long been a major center of such retail activity; many of the shops have been renovated since the late 1990s and a nine-story Marriott hotel was built in this immediate district in 1996.
The oldest campus buildings are located west of Old Main. Most of the buildings east of Old Main date from the 1940s to the 1980s, with a few recent buildings constructed in the years since 1990.
The Student Union Memorial Center, located on the north side of the Mall east of Old Main, was completely reconstructed between 2000 and 2003, replacing a 270,000-square-foot (25,000 m2) structure originally opened in 1951 (with additions in the 1960s). The new $60 million student union has 405,000 square feet (37,600 m2) of space on four levels, including 14 restaurants (including a food court with such national chains as Burger King, Panda Express, Papa John''''''''''''''''s Pizza and Chick-fil-A), a new two-level bookstore (that includes a counter for Clinique merchandise as well as an office supplies section sponsored by Staples with many of the same Staples-branded items found in their regular stores), 23 meeting rooms, eight lounge areas (including one dedicated to the USS Arizona), a computer lab, a U.S. Post Office, a copy center named Fast Copy, and a video arcade.
For current museum hours, fees, and directions see "campus visitor''''''''''''''''s guide" in the external links.
Much of the main campus has been designated an arboretum. Plants from around the world are labeled along a self-guided plant walk. The Krutch Cactus Garden includes the tallest Boojum tree in the state of Arizona.[6] (The university also manages Boyce Thompson Arboretum State Park, located c. 85 miles (137 km) north of the main campus.)
Two herbaria are located on the University campus and both are referred to as "ARIZ" in the Index Herbariorum
The University of Arizona Herbarium - contains roughly 400,000 specimens of plants.
The Robert L. Gilbertson Mycological Herbarium - contains more than 40,000 specimens of fungi.
The Arizona State Museum is the oldest anthropology museum in the American Southwest.
The Center for Creative Photography features rotating exhibits. The permanent collection includes over 70,000 photos, including many Ansel Adams originals.
University of Arizona Museum of Art.

Flandrau Science Center has exhibits, a planetarium, and a public-access telescope.
The University of Arizona Mineral Museum is located inside Flandrau Science Center. The collection dates back to 1892 and contains over 20,000 minerals from around the world, including many examples from Arizona and Mexico.
The University of Arizona Poetry Center
The Stevie Eller Dance Theatre, opened in 2003 (across the Mall from McKale Center) as a 28,600-square-foot (2,660 m2) dedicated performance venue for the UA''''''''''''''''s dance program, one of the most highly regarded university dance departments in the United States. Designed by Gould Evans, a Phoenix-based architectural firm, the theatre was awarded the 2003 Citation Award from the American Institute of Architects, Arizona Chapter. [7]
The football stadium has the Navajo-Pinal-Sierra dormitory in it. The dorm rooms are underneath the seats along the South and East sides of the stadium.
Academics

In 2005, the Association of Research Libraries, in its &quot;Ranked Lists for Institutions for 2005&quot; (the most recent year available), ranked the UA libraries as the 33rd overall university library in North America (out of 113) based on various statistical measures of quality; this is one rank below the library of Duke University, one rank ahead of that of Northwestern University[24] (both these schools are members, along with the UA, of the Association of American Universities).
As of 2006, the UA''''''''''''''''s library system contains nearly five million volumes.
The Main Library, opened in 1976, serves as the library system''''''''''''''''s reference, periodical, and administrative center; most of the main collections and special collections are housed here as well. The Main Library is located on the southeast quadrant of campus near McKale Center and Arizona Stadium.
In 2002, a $20 million, 100,000-square-foot (10,000 m2) addition, the Integrated Learning Center (ILC), was completed; it is a home base for first-year students (especially those undecided on a major) which features classrooms, auditoriums, a courtyard with an alcove for vending machines, and a greatly expanded computer lab (the Information Commons) with several dozen Gateway and Apple Macintosh G5 workstations (these computers are available for use by the general public (with some restrictions) as well as by UA students, faculty and staff). Much of the ILC was constructed underground, underneath the east end of the Mall; the ILC connects to the basement floor of the Main Library through the Information Commons. As part of the project, additional new office space for the Library was constructed on the existing fifth floor.
The Science and Engineering Library is in a nearby building from the 1960s that houses volumes and periodicals from those fields. The Music Building (on the northwest quadrant of campus where many of the fine arts disciplines are clustered) houses the Fine Arts Library, including reference collections for architecture, music (including sheet music, recordings and listening stations), and photography. There is a small library at the Center for Creative Photography, also in the fine arts complex, devoted to the art and science of photography. The Law Library is in the law building.
The libraries at University of Arizona are expecting a 15 percent budget cut for the 2009 fiscal year. They will begin to explore the possibilities of cutting staff, cutting online modules, and closing some libraries. The biggest threat is the possible closure of 11 libraries. The staff is projected to decline from 180 employees to 155 employees. They also intend to cut face-face instructional program that teaches students in English 101 and 102 how to navigate the library. This will now be taught online.
[edit] Athletics
Main article: Arizona Wildcats
Like many large public universities in the U.S., sports are a major activity on campus, and receive a large operating budget. Arizona''''''''''''''''s athletic teams are nicknamed the Wildcats, a name derived from a 1914 football game with then California champions Occidental College, where the L.A. Times asserted that, &quot;the Arizona men showed the fight of wildcats.&quot;[25] The University of Arizona participates in the NCAA''''''''''''''''s Division I-A in the Pacific-10 Conference, which it joined in 1978.
[edit] Men''''''''''''''''s basketball
Main article: Arizona Wildcats men''''''''''''''''s basketball
The men''''''''''''''''s basketball team has been one of the nation''''''''''''''''s most successful programs since Lute Olson was hired as head coach in 1983, and is still known as a national powerhouse in Division I men''''''''''''''''s basketball.[26] As of 2009, the team has reached the NCAA Tournament 25 consecutive years, which is the longest active and second-longest streak in NCAA history (University of North Carolina at Chapel Hill had the longest streak with 27).[27] The Wildcats have reached the Final Four of the NCAA tournament in 1988, 1994, 1997, and 2001. In 1997, Arizona defeated the University of Kentucky, the defending national champions, to win the NCAA National Championship (NCAA Men''''''''''''''''s Division I Basketball Championship) by a score of 84–79 in overtime; Arizona''''''''''''''''s first national championship victory. The 1997 championship team became the first and only in NCAA history to defeat three number-one seeds en route to a national title (Kansas, North Carolina and Kentucky -- the North Carolina game being the final game for longtime UNC head coach Dean Smith). Point guard Miles Simon was chosen as 1997 Final Four MVP (Simon was also an assistant coach under Olson from 2005–08). The Cats also boast the third highest winning percentage over the last twenty years. Arizona has won a total of 21 conference championships in its'''''''''''''''' programs history.
The Wildcats play their home games at the McKale Center in Tucson. A number of former Wildcats have gone on to pursue successful professional NBA careers (especially during the Lute Olson era), including Gilbert Arenas, Richard Jefferson, Mike Bibby, Jason Terry, Sean Elliott, Damon Stoudamire, Luke Walton, Hassan Adams, Salim Stoudamire, Andre Iguodala, Channing Frye, Brian Williams (later known as Bison Dele), Sean Rooks, Jud Buechler, Michael Dickerson and Steve Kerr. Kenny Lofton, now best known as a former Major League Baseball star, was a four year letter winner as a Wildcat basketball player (and was on the 1988 Final Four team), before one year on the Arizona baseball team. Another notable former Wildcat basketball player is Eugene Edgerson, who played on the 1997 and 2001 Final Four squads, and is currently one of the primary stars of the Harlem Globetrotters as &quot;Wildkat&quot; Edgerson.
Before Lute Olson''''''''''''''''s hire in 1983, Arizona was the first major Division I school to hire an African American head coach in Fred Snowden, in 1972. After a 25-year tenure as Arizona head coach, Olson announced his retirement from the Arizona basketball program in October 2008. After two seasons of using interim coaches, Arizona named Sean Miller, head coach at Xavier University, as its new head basketball coach in April 2009.
The football team began at The University of Arizona in 1899 under the nickname &quot;Varsity&quot; (a name kept until the 1914 season when the team was deemed the &quot;Wildcats&quot;).[28]
The football team was notably successful in the 1990s, under head coach Dick Tomey; his &quot;Desert Swarm&quot; defense was characterized by tough, hard-nosed tactics. In 1993, the team had its first 10-win season and beat the University of Miami Hurricanes in the Fiesta Bowl by a score of 29–0. It was the bowl game''''''''''''''''s only shutout in its then 23-year history. In 1998, the team posted a school-record 12–1 season and made the Holiday Bowl in which it defeated the Nebraska Cornhuskers. Arizona ended that season ranked 4th nationally in the coaches and API poll. The 1998 Holiday Bowl was televised on ESPN and set the now-surpassed record of being the most watched of any bowl game in that network''''''''''''''''s history (the current record belongs to the 2005 Alamo Bowl between Michigan and Nebraska). The program is led by Mike Stoops, brother of Bob Stoops, the head football coach at the University of Oklahoma.
[edit] Baseball
Main article: Arizona Wildcats baseball
The baseball team had its first season in 1904. The baseball team has captured three national championship titles in 1976, 1980, and 1986, all coached by Jerry Kindall. Arizona baseball teams have appeared in the NCAA National Championship title series a total of six times, including 1956, 1959, 1963, 1976, 1980, and 1986 (College World Series). The team is currently coached by Andy Lopez; aided by Assistant Coach Mark Wasikowski, Assistant Coach Jeff Casper and Volunteer Assistant Coach Keith Francis. Arizona baseball also has a student section named The Hot Corner. Famous UA baseball alums include current Boston Red Sox manager Terry Francona, Cleveland Indian Kenny Lofton, Yankee Shelley Duncan, Brewers closer Trevor Hoffman, Diamondbacks third-base coach Chip Hale, former 12-year MLB pitcher and current minor league coach Craig Lefferts, longtime MLB standout J. T. Snow, star MLB pitchers Don Lee, Carl Thomas, Mike Paul, Dan Schneider, Rich Hinton and Ed Vosberg, NY Giants slugger Hank Leiber, Yankee catcher Ron Hassey, and Red Sox coach Brad Mills. Former Angels and Cardinals (among others) pitcher Joe Magrane is also a UA alum.
[edit] Softball
The Arizona softball team is among the top programs in the country and a perennial powerhouse. The softball team has won eight NCAA Women''''''''''''''''s College World Series titles, in 1991, 1993, 1994, 1996, 1997, 2001, 2006 and 2007 under head coach Mike Candrea (NCAA Softball Championship). Arizona defeated the University of Tennessee in the 2007 National Championship series in Oklahoma City. The team has appeared in the NCAA National Championship in 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 2001, 2002, 2006, and 2007 (a feat second only to UCLA), and has reached the College World Series 19 of the past 20 years. Coach Candrea, along with former Arizona pitcher Jennie Finch, led the 2004 U.S. Olympic softball team to a gold medal in Athens, Greece. The Wildcat softball team plays at Rita Hillenbrand Memorial Stadium.
[edit] Men''''''''''''''''s and women''''''''''''''''s golf
The university''''''''''''''''s golf teams have also been notably successful. The men''''''''''''''''s team won a national championship in 1992 (NCAA Division I Men''''''''''''''''s Golf Championships), while the women''''''''''''''''s team won national championships in 1996 and 2000 (NCAA Women''''''''''''''''s Golf Championship).
A strong athletic rivalry exists between the University of Arizona and Arizona State University located in Tempe. The UA leads the all-time record against ASU in men''''''''''''''''s basketball (138-73), football (44–35–1), and baseball (224–189–1) as of January 2006. The football rivalry game between the schools is known as &quot;The Duel in the Desert.&quot; The trophy awarded after each game, the Territorial Cup, is the nation''''''''''''''''s oldest rivalry trophy, distinguished by the NCAA. Rivalries have also been created with other Pac-10 teams, especially University of California, Los Angeles which has provided a worthy softball rival and was Arizona''''''''''''''''s main basketball rival in the early and mid-1990s.
[edit] Mascot
The University mascot is an anthropomorphized wildcat named Wilbur. The identity of Wilbur is kept secret through the year as the mascot appears only in costume. In 1986, Wilbur married his longtime wildcat girlfriend, Wilma. Together, Wilbur and Wilma appear along with the cheerleading squad at most Wildcat sporting events.[29] Wilbur was originally created by Bob White as a cartoon character in the University''''''''''''''''s humor magazine, Kitty Kat. From 1915 through the 1950s the school mascot was a live bobcat, a species known locally as a wildcat. This succession of live mascots were known by the common name of Rufus Arizona, originally named after Rufus von Kleinsmid, president of the university from 1914 to 1921. 1959 marked the creation of the first incarnated Wilbur, when University student John Paquette and his roommate, Dick Heller, came up with idea of creating a costume for a student to wear. Ed Stuckenhoff was chosen to wear the costume at the homecoming game in 1959 against Texas Tech and since then it has become a long-standing tradition. Wilbur will celebrate his 50th birthday in November 2009.
Officially implemented in 2003, Zona Zoo is the official student section and student ticketing program for the University of Arizona Athletics. The Zona Zoo program is co-owned by the Associated Students of the University of Arizona (ASUA) and Arizona Athletics, the program is run by a team of spirited individuals called the Zona Zoo Crew. Zona Zoo is one of the largest and most spirited student sections in NCAA Division I Athletics.
Notable venues
McKale Center, opened in 1973, is currently used by men''''''''''''''''s and women''''''''''''''''s basketball, women''''''''''''''''s gymnastics, and women''''''''''''''''s volleyball. The official capacity has changed often. The largest crowd to see a game in McKale was 15,176 in 1976 for a game against the University of New Mexico, a main rival during that period. In 2000, the floor in McKale was dubbed Lute Olson Court, for the basketball program''''''''''''''''s winningest coach. During a memorial service in 2001 for Lute''''''''''''''''s wife, Bobbi, who died after a battle with ovarian cancer, the floor was renamed Lute and Bobbi Olson Court. In addition to the playing surface, McKale Center is host to the offices of the UA athletic department. McKale Center is named after J.F. Pop McKale, who was athletic director and coach from 1914 through 1957. Joe Cavaleri (&quot;The Ooh-Aah Man&quot;) made his dramatic and inspiring appearances there.
Arizona Stadium, built in 1928 and last expanded in 1976, seats over 56,000 patrons. It hosts American football games and has also been used for university graduations. The turf is bermuda grass, taken from the local Tucson National Golf Club. Arizona football''''''''''''''''s home record is 258-139-12. The largest crowd ever in Arizona Stadium was 59,920 in 1996 for a game against Arizona State University.
Jerry Kindall Field at Frank Sancet Stadium hosts baseball games.
Rita Hillenbrand Memorial Stadium hosts softball games.

+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
When, towards late 1945, the Einheits-Chassis for the German combat tanks (the "E" series of medium and heavy tanks) reached the front lines, several heavily armed anti-aircraft turrets had been developed, including the 30mm Kugelblitz, based on the outdated Panzer IV, the "Coelian" turret with various armament options for the Panzer V Panther hull, and there were twin 55 mm as well as single and even 88mm cannon systems for the new E-50, E-75 and E-100 chassis'.
With these new weapons for medium- and high-altitude targets, Firepower was considerably increased, but the tank crews still had to rely on traditional visual tracking and aiming of targets. One potential solution in which the German Heeresleitung was highly interested from the start was the use of the Luftwaffe’s new radar technology for early target identification and as an aiming aid in poor weather conditions or even at night. The German Luftwaffe first introduced an airborne interception radar in 1942, but these systems were bulky and relied upon large bipolar antenna arrays. These were not suitable for any use in a ground vehicle, lest to say in a tank that would also carry weapons and ammunition.
A potential solution appeared in late 1944 with the development of the FuG 240 "Berlin". It was an airborne interception radar, too, but it was the first German radar to be based on the cavity magnetron, which eliminated the need for the large multiple dipole-based antenna arrays seen on earlier radars, thereby greatly increasing the performance of the night fighters. The FuG 240 with a rotating dish antenna was introduced by Telefunken in April 1945, primarily in Junkers Ju 88G-6 night-fighters, behind a plywood radome which considerably improved aerodynamics. This so greatly reduced drag compared to the late-model Lichtenstein and Neptun systems that the fighters regained their pre-radar speeds and made them competitive again. The FuG 240 was effective against bomber-sized targets at distances of up to 9 kilometers (5.5 mi), or down to 0.5 kilometer, which eliminated the need for a second, short-range radar system.
Right before the FuG 240's roll-out with the Luftwaffe, the Heer insisted on a ground-based derivative for its anti-aircraft units. Political pressure from Berlin convinced the RLM to share the new technology, and Telefunken was ushered to adapt the radar system to an armored ground vehicle in February 1945.
It soon became clear that the FuG 240 had several drawbacks for this task. On one side, ground clutter and the natural horizon limited the system's range and low-level effectiveness, but its 9 km range in free space made high altitude surveillance possible – just enough for the effective interception of Allied bombers that attacked important point targets. Furthermore, the whole system, together with its power supply and a dirigible dish antenna, took up a lot of space, so that its integration into a tank-based anti-aircraft vehicle like an SPAAG as an autonomous, stand-alone solution was ruled out.
A workable solution eventually came as a technical and tactical compromise: the army’s anti-aircraft tanks were to be grouped together in so-called Panzer-Fla-Züge, which consisted of several (typically four) SPAAGs and an additional, dedicated radar surveillance and command unit, so that the radar could guide the tank crews towards incoming targets – even though the gun crews still had to rely on visual targeting.
Two respective guidance vehicles developed, a light and a heavy one. The light one, intended against low-flying targets like the Ilyushin Il-2 on the Eastern front, became the 8x8 Funkmess-/Flak-Kommandowagen Sd.Kfz. 234/6. The heavy variant, with a bigger antenna and a more powerful emitter, became the Mittlerer Funkmess-/Flak-Kommandopanzer Sd.Kfz. 282. In contrast to the light and compact Sd.Kfz. 234/6, the Sd.Kfz. 282’s complete radar and observation system was installed in a new turret, so that it could be simply mounted onto the new E-50 Einheitspanzer battle tank hull.
This new, box-shaped turret had been developed by Rheinmetall, together with Telefunken, and was based on the turret design for the new 55 mm twin anti-aircraft cannon. It had a maximum armor of 60mm at the front and held all of the radar equipment, christened "Basilisk", after the monster from medieval mythology with a petrifying sight. The turret held a crew of three: a commander, a radar operator, and an observer for the optical rangefinder. The rest of the crew, the driver and a radio operator, sat in the hull. No armament was fitted, even though a light machine gun could be mounted on the roof for self-defense, even though it could not be operated from the inside. A heavier armament was not deemed necessary since the vehicle would stay close to the heavily armed tanks/SPAAGs it would typically accompany.
The Basilisk radar’s rotating dish antenna had a diameter of 90 cm (35 ½ inches) and was installed at the turret's front under a hard vinyl cover. Power of the modified FuG 240 was 25kW, with a search angle of +80/− 5° and a frequency range: 3,250–3,330MHz (~10 cm). Range was, due the bigger antenna and a higher emitter output, increased to 0.5–11.0 kilometer, even though only under ideal conditions. Power came from a dedicated generator that was connected to the E-50’s V-12 Maybach HL 234 gasoline engine.
Beyond the radar system, the vehicle was furthermore equipped with a powerful visual coincidence range finder in the turret, combined with an analogue computer, the Kommandogerät (KDO) 40 Telemeter. This system had been introduced in 1941 as a guidance tool for stationary anti-aircraft units equipped with the 88 mm and the 105 mm Flak, but it had so far – due to its size and bulk – only been deployed on an unarmored trailer
The KDO 40 and similar sights worked as follows: Light from the target entered the range finder through two windows located at either end of the instrument. At either side, the incident beam was reflected to the center of the optical bar by a pentaprism, and this optical bar was ideally made from a material with a low coefficient of thermal expansion so that optical path lengths would not change significantly with temperature. The reflected beam first passed through an objective lens and was then merged with the beam of the opposing side with an ocular prism sub-assembly to form two images of the target which were viewed by the observer through the eyepiece. Since either beam entered the instrument at a slightly different angle the resulting image, if unaltered, would appear blurry. Therefore, in one arm of the instrument, a compensator was integrated which could be adjusted by the operator to tilt the beam until the two images matched. At this point, the images were said to be in coincidence. The degree of rotation of the compensator determined the range to the target by simple triangulation, allowing the calculation of the distance to the observed object.
Fixed target reading with the device mounted in the Sd.Kfz. 282 turret was possible on targets from 3,000 to 20,000 m. Aerial courses could be recorded at all levels of flight and at a slant range between 4,000 and 18,000 m - enough for visual identification beyond an anti-aircraft group's effective gun ranges and perfectly suitable for long range observation, so that the Sd.Kfz. 282 also had excellent reconnaissance and observation capabilities. The rangefinder’s optical bar had a massive span of 400 cm (157.5 in) and went right through the turret, just above the radar device installation. The whole device, together with its armored fairing, was 4,60 m (15 ft 1 in) wide, so that it protruded from the turret on both sides over the lower hull. The odd and unwieldy installation quickly earned the vehicle nicknames like "Hirsch (stag)", "Zwo-Ender" (a young stag with just two antlers) or “Ameise” (ant). None of these were official, though. In order to protect the Telemeter on the way, the turret was normally turned by 90° and hidden under a tarpaulin, in order not to give away any details of the highly classified equipment.
However, development of the Einheitspanzer family lagged behind schedule, and in early 1945 no E-50 chassis was available for the highly specialized Sd.Kfz. 282 – battle tanks and SPGs were in higher demand. As an alternative, the turret was quickly adapted for different tank hulls, namely the Sd.Kfz. 171, the Panzer V ‘Panther’ medium tank and the heavy Sd.Kfz. 181 ‘Tiger I’. Tests with both hulls in spring 1945 were successful, but only the lighter ‘Panther’ hull was chosen because it was lighter overall, more mobile and available in sufficient numbers for a quick roll-out. In this configuration, the system received the designation Sd.Kfz. 282/1, while the original Sd.Kfz. 282 designation was reserved for the originally planned E-50 chassis variant.
The first vehicles reached, together with the new FlaK tanks, the front units in September 1945. Operating independently, they were primarily allocated to the defense of important production sites and the city of Berlin, and they supported tank divisions through early warning duties and visual long-range reconnaissance. Operationally, the Sd.Kfz. 282’s sensor setup with its combined visual and radar input turned out to be surprisingly successful. The combination of the Basilisk radar with the KDO 40 rangefinder allowed a time from initial target acquisition to the first AA shot of less than 20 seconds, which was impressive for the time – typically, simple visual target acquisition took 30 seconds or more. First shot hit probability was appreciably improved, too, and even quick passes of aircraft at low altitudes could be precalculated, if the radar was not obstructed.
However, the radar remained capricious, its performance rather limited and the unarmored antenna fairing at the turret’s front was easily damaged in combat, even by heavy machinegun fire. But the Sd.Kfz. 282 offered, when the vehicle was placed in a location with a relatively free field of view (e. g. on a wide forest clearance or in an open field), a sufficient early warning performance against incoming bombers at medium to high altitudes, and it also appreciably mobilized the bulky but valuable KDO 40 device. It now could easily be moved around and keep up with the pace of motorized battle groups that the Panzer-Fla-Züge units were supposed to protect.
Until the end of hostilities, probably thirty Sd.Kfz. 282/1s were completed from newly built (Ausf. F, recognizable through the simpler all-metal wheels) or from refurbished earlier Panzer V chassis of various types before production switched in early 1946 to the E-50 chassis which had eventually become available in sufficient numbers.

The kit and its assembly:
Another submission to the “Recce & Surveillance” group build at whatifmodellers.com in July 2021, and actually a good occasion to tackle a project that I had on my list for some years. A long while ago I bought a resin conversion set with a (purely fictional) Heer ‘46 anti-aircraft surveillance radar system, based on an E-50 chassis. Unfortunately, I cannot identify the manufacturer, but this 1:72 conversion set was/is nicely molded, with delicate details, no bubbles or flash and it even came with a commander figure for an optional open hatch on top as well as a pair of delicate brass antennae.
Even though I could have mounted this replacement turret onto a Trumpeter or Modelcollect E-50/75 chassis, I rather decided to create an earlier (1945 time frame) interim vehicle on a late Panzer V ‘Panther’ basis, mostly because it would be more compact and I doubt that brand new E-50/75s would have been “wasted” on second line/support vehicles like this mobile surveillance/commando post for anti-aircraft units?
The Panther chassis is the old Hasegawa kit for an Ausf. G tank from 1973, chosen because of its good fit, simplicity and the vinyl tracks, which I prefer. However, the kit clearly shows its age and some weak/soft details (e. g. the gratings on the engine deck), but it was enough for my plans and easy to handle.
Both turret and hull were built separately and basically OOB, combined with an adjusted turret ring. The Kdo 40’s “antlers” are to be glued directly to the turret’s flanks, but I reinforced the connections with wire. I also replaced the set’s brass antennae with heated sprue material and used a surplus PE detail set from a Modelcollect E-50/75 to hide the crude engine openings and change the overall look of the Panther a little. Some storage boxes as well as spare track links were added to the flanks, stuff collected from the scrap box.
To emphasize the refurbished character of the vehicle I left away the Panther’s side skirts – these were easily lost in battle, anyway, and probably have rather been allocated to battle tanks than to 2nd line support vehicles, despite leaving the Panther’s lower hull under the mudguards vulnerable.
Painting and markings:
Even though the paint scheme on this model is based on German standard colors, it is a little special. Late in real-world WWII some Panzer Vs received a unique, uniform RAL 6003 (Olivgrün) factory finish instead of the usual all-over RAL 7028 (Dunkelgelb) or the bare oxide red primer finish, onto which the frontline units would add individual camouflage, depending on the theatre of operations and whatever paint or application tool was at hand. This special green livery was adopted for the model, including the new turret. The individual camouflage consists of diagonal stripes in Dunkelgelb and Rotbraun (RAL 8017), added on top of the green basis with rather sharp and straight edges and only to the vertical surfaces. The practice to leave out the horizontal surfaces was called “Sparanstrich” (literally “economy paintwork”), an attempt to save the more and more scarce paint.
This rather odd style was actually applied to several late war Panther tanks – even though I am personally not certain about this pattern’s effectiveness? Maybe a kind of dazzle effect was sought for?
The basic green became a modern-day RAL 6003 from the rattle can (which is very close to FS 34102, just a tad lighter), applied in a rather cloudy fashion on top of an initial coat of Oxide Red primer (RAL 3009) overall, also from the rattle can. On top of that the stripes were painted with a brush, partly masked but mostly free-handedly. For some variation I used this time Tamiya XF-60 (a rather pale interpretation of Dunkelgelb which IMHO lacks a greenish hue and rather looks like a desert sand tone) and XF-64 (a rich whole milk chocolate tone) to create the additional camouflage, not fully opaque so that the impression of thinly/hastily applied paint was reinforced.
Once dry, the whole surface received a very dark brown washing with thinned acrylic paint and surface details were emphasized through dry-brushing with earth brown and beige.
For a different look (and to break up the tank’s bulky outlines) I applied camouflage nets to the model, realized with gauze bandages drenched in Tamyia XF-62 (Olive Drab) and mounted into place around the turret and at the front of the hull while still slightly wet.
Decals were puzzled together from various German tank sheets. The kit was sealed with matt acrylic varnish, what also fixed the cammo nets in place. The originally shiny black vinyl tracks were also painted/weathered, with a wet-in-wet mix of grey, iron, black and red brown (all acrylics). Once mounted into place, mud and dust were simulated around the running gear and the lower hull with a greyish-brown mix of artist mineral pigments.
Not a spectacular build, but I am happy that I eventually had the opportunity and motivation to tackle this project that had been lingering for years in the The Stash™. The result looks really good – the anonymous resin set is/was excellent, and combined with the Panther hull, the whole thing looks very credible. I am only a bit sad that the odd, almost artistic camouflage got a little lost under the cammo nets and the equipment on the hull, and the dust/dirt on the lower areas blurs the three basic colors even more. Well, you cannot have everything at once, and I might re-use this scheme on a “cleaner” future build.
+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The Flakpanzer Coelian comprised a family of self-propelled anti-aircraft gun tanks, designed by Rheinmetall during World War II for the German armed forces. In the first years of the war, the Wehrmacht had only little interest in developing self-propelled anti-aircraft guns, but as the Allies developed air superiority, the need for more mobile and better-armed self-propelled anti-aircraft guns increased.
As a stopgap solution the Wehrmacht had adapted a variety of wheeled, half-track and tracked vehicles to serve as mobile forward air defense positions to protect armor and infantry units in the field as well as for temporary forward area positions such as mobile headquarters and logistic points. As Allied fighter bombers and other ground attack aircraft moved from machine gun armament and bombing to air-to-ground rockets, the air defense positions were even more vulnerable. The answer was to adapt a tank chassis with a specialized turret that would protect the gun crews while they fired upon approaching Allied aircraft.
Initial AA-tank designs were the ‘Möbelwagen’ and the ‘Wirbelwind’, effectively both conversions of refurbished Panzer IV combat tank chassis’ with open platforms or open turrets with four 20mm cannon. Alternatively, a single 37mm AA gun was mounted, too, resulting in the more effective ‘Ostwind’ tank – but all these vehicles were just compromises and suffered from light armor and lack of crew protection.
Further developments led to the ‘Kugelblitz’, another Panzer IV variant, but this time the ball-shaped turret was effectively integrated into the hull, resulting in a low silhouette and a fully protected crew. Another new feature was the use of the Mauser MK 103 machine cannon – a lightweight, belt-fed aircraft gun with a gas-powered action mechanism, first employed on board of the Hs 129 attack aircraft against ground targets, including tanks. The Mk 103 had a weight of only 141 kg (311 lb) and a length of 235 cm (93 in) (with muzzle brake). Barrel length was 134 cm (53 in), resulting in Kaliber L/44.7 (44.7 calibres).
Anyway, the Kugelblitz could only mount two of these guns in its very cramped and complicated tilting turret. Venting and ammunition feed problems could also not be solved, so that the innovative vehicle never made it beyond the prototype and evaluation stage, even though the integration of the Kugelblitz turret into the hull of the Jagdpanzer ‘Hetzer’ was considered for some time.
In parallel, the promising MK 103 was also tested in the four-gun carriage of the Wirlbelwind’s 20 mm Flakvierling 38 mount, resulting in the ‘3 cm Flakvierling 103/38’ and the respective ‘Zerstörer 45’ tank prototype. But this was, effectively, only a juiced up version of the obsolete ‘Wirbelwind’, again with only a roofless and vulnerable turret and the obsolete Panzer IV as base. The ‘Zerstörer 45’ was consequently rejected, but the firepower of the four guns was immense: Rate of fire of a single MK 103 was 400 - 450 RPM, and the rounds carried three times as much explosive charge as a Soviet 37 mm round. Both HE/M and APCR rounds were available for the MK 103. Muzzle velocity was 860-940 m/sec, paired with a high degree of accuracy. The armor penetration for APCR was 42–52 mm (1.7–2.0 in) / 60° / 300 m (980 ft) or 75–95 mm (3.0–3.7 in) / 90° / 300 m (980 ft) – more than enough for aircraft, and even dangerous for many combat tanks when hitting more lightly armored areas. Anyway, it was not possible to combine four of these 30mm guns with a favorably shaped, completely enclosed turret for an effective front line anti-aircraft tank that could stand its own among the armored combat units.
The solution to this problem eventually materialized in 1943 with the decision to completely abandon the limiting Panzer IV chassis and build a new generation of anti-aircraft tanks on the basis of the larger (and heavier) Panzer V medium battle tank, the ‘Panther’. Its chassis had in the meantime become available in considerably numbers from damaged and/or recovered combat tanks, and updated details like new turrets or different wheels were gradually introduced into production and during refurbishments.
The Panther could mount a considerably larger and heavier turret than the previous standard tank chassis like the Panzer III and IV, and this potential was full exploited – as well as the possibility to increase the weapon system’s weight, thanks to the sturdier chassis. Rheinmetall’s new, fully enclosed, 360° rotating turret could carry a wide array of weapons and ammunition (all were belt-fed), a crew of three and also offered a good protection through a sloped, frontal armor of 70mm thickness. Traverse and elevation of the turret was hydraulic, allowing a full elevation in just over four seconds, and a 360° traverse in 15.5 seconds. The initial version was armed with two 3.7 cm FlaK 43 guns, as a compromise between range, firepower and rate of fire. Beyond this initial variant, Rheinmetall developed the ‘Coelian’ turret in various versions, too, including fully enclosed turrets with a single 55 mm gun and with four 20mm MG 151/20 guns.
Eventually, in May 1944, a complete family of turrets with different armament options was cleared for production: the standard Coelian I, with a revised mount for the twin 3.7 cm FlaK 43 guns, a heavier variant with twin 55 mm guns against larger, high-flying targets (Coelian II; the guns were based on another aircraft weapon, the MK 214), and finally the Coelian III with four Mk 103 cannon against low-flying attack aircraft and soft/lightly armored ground targets. The variant with four 20 mm guns had been dropped, since it did not offer and added value compared to the Coelian III. All these vehicles ran under the SdKfz. 171/3 designation, with suffixes (A-C) to distinguish their armament in a more or less standardized turret.
Even though ground-based, mobile radar systems were under development at that time, all these turrets had to rely only on optical sensors, even though very effective optical rangefinders were introduced. All the turrets of the Coelian family were to be mounted on revamped Panzer V chassis, simply replacing the former combat tank turrets (either the original production turret from the A, D and G variant or the newly introduced Schmalturm from the F version). Theoretically, they could have also been mounted onto the Panzer VI ‘Tiger’ chassis, but due to this type’s weight and complexity, this was not carried out.
However, the SdKfz. 171/3 Panther/Coelian family designation had in the meantime also just become an interim solution: Plans had been made to start the production of a completely new, simplified tank vehicle family, the so-called ‘Einheitspanzer’. The resulting standard combat tanks (called E-50 and E-75, based on their weight class in tonnes) and their respective hulls would be based on the large Königstiger battle tank, and potentially accept even bigger turrets and weapons. Consequentially, while production of the Coelian turrets and the conversion of 2nd hand and by the time also new Panther hulls of all variants was just gaining momentum in late 1944, work for the new Einheitspanzer tanks and their weaponry had already started.
Roundabout 300 Coelian tanks reached frontline units, two third of them were factory-built, and in the course of early 1945 the Coelian family had gradually replaced most of the outdated Panzer IV AA variants and SPAAGs with open turrets. The Coelian tanks were soon joined by the newly produced, dedicated Flakpanzer variants of the Einheitspanzer family, including a twin 55 mm gun on the E-50 chassis and also a monstrous 140 ton anti-aircraft variant of the heavy E-100 chassis, equipped with an automatic twin 8.8cm Flak in a fully enclosed and heavily armored turret.

The kit and its assembly:
This was a spontaneous build, in the wake of other recent whif tanks and using some leftover parts from the kit pile(s). Things started with a KORA 1:72 resin conversion kit with a 2x 37mm FlaK Coelian turret for a Panther chassis – but with broken and bent gun barrels. I had actually stashed the parts away for a potential mecha build/conversion, long ago, but while doing legwork for late German WWII tanks I recently came again across the various anti-aircraft tank designs. And I wondered if mounting the Coelian turret on a Panzer IV chassis would be possible and lead to a compact (and whiffy) new vehicle?
Well, it would not work, because the Coelian turret needs a considerably bigger turret bearing diameter than anything the Panzer IV hull could realistically handle (even the Panther’s Schmalturm is actually a little too wide…), and so I folded the idea up again and put it onto the “vague ideas” pile.
…until I stumbled upon the leftover hull from a Hasegawa Panther Ausf. F in the donor kits pile, which had originally given both of its OOB turrets (a Schmalturm and a standard model) to other conversions. While mating the Coelian turret with its originally intended hull was not a sexy project, I eventually did so, because I could effectively use two leftovers for something sound and well-balanced.
Concerning the assembly phase, there’s not much to tell about the Hasegawa Panther Ausf. F. Fit is good, a simple kit, and it comes, as a benefit, with optional all-steel wheels which I used for my conversion, changing the overall look to a true late war model. Only the opening for the turret had to be widened in order to accept the new resin turret.
The latter only consists of two parts: the massive core section and a separate weapon mount. The latter was in so far modified that I added a simple metal peg which can be switched between two holes in the turret hull, for two gun positions.
Since the original gun barrels had to be replaced, anyway, I did a thorough (and fictional) modification: I used four 1:48 20 mm brass barrels for a Flak 38 Flakvierling (from RB Models) and mounted them in two staggered pairs onto the original cannon fairing. The resulting gun array looks impressive and even realistic, and, thanks to the scale-o-rama effect, the 1:48 parts have the perfect size for 30 mm cannon barrels in 1:72!
Painting and markings:
Something “German”, but nothing spectacular, so I ended up with another variant of the Hinterhalt scheme, found on a Jagdpanther from the Ardennenoffensive period. In this case, the prominent colors are Dunkelgelb and Olivgrün in broad stripes, separated by blurred, thin lines made of Rotbraun.
As a little twist I wanted to modify the scheme in so far that this vehicle was to show its conversion heritage in a workshop, so hull and turret received different basic tones as an initial step.
The hull and all wheels were painted with matt RAL 7028 (a modern equivalent to the WWII Dunkelgelb), while the turret received a red primer coat with Oxidrot (RAL 3009). On top of these, wide green bands (RAL 6003 from Modelmaster) and separating russet (Humbrol 113) stripes were painted with brushes. In order to brighten up the relatively dark turret, some yellow mottles were added on the Oxidrot areas (using Revell 16).
Once dry, the whole surface received a sand paper treatment, so that the RAL 7028 would shine through here and there, as if worn out. After a dark brown wash, details were emphasized with dry-brushing in light grey and beige. Decals were puzzled together from various German tank sheets, and the kit finally sealed with matt acrylic varnish.
The black vinyl tracks were also painted/weathered, with a wet-in-wet mix of black, iron and red brown (all acrylics). Once they were mounted into place, mud and dust around the running gear and the lower hull was simulated with a greyish-brown mix of artist mineral pigments.
A bit of recycling and less exotic than originally hoped for – but it’s still a whiffy tank model, and its proximity to the real but unrealized Coelian project makes this one even more subtle. Pile reduction, one by one…
The University of Arizona (also referred to as UA, U of A, or Arizona) is a land-grant and space-grant public institution of higher education and research located in Tucson, Arizona, United States. The University of Arizona was the first university in the state of Arizona, founded in 1885 (twenty-seven years before the Arizona Territory achieved statehood), and is considered a Public Ivy. UA includes the only medical school in Arizona that grants M.D. degrees. In 2006, total enrollment was 36,805 students. UA is governed by the Arizona Board of Regents.
The University of Arizona was approved by the Arizona Territory''''''''''''''''s Thieving Thirteenth Legislature in 1885. The city of Tucson had hoped to receive the appropriation for the territory''''''''''''''''s mental hospital, which carried a $100,000 allocation instead of the $25,000 allotted to the territory''''''''''''''''s only university (Arizona State University was also chartered in 1885, but at the time it was created as Arizona''''''''''''''''s normal school, and not a university). Tucson''''''''''''''''s contingent of legislators was delayed in reaching Prescott due to flooding on the Salt River and by the time they arrived back-room deals allocating the most desirable territorial institutions had already been made. Tucson was largely disappointed at receiving what was viewed as an inferior prize. With no parties willing to step forth and provide land for the new institution, the citizens of Tucson prepared to return the money to the Territorial Legislature until two gamblers and a saloon keeper decided to donate the land necessary to build the school. Classes met for the first time in 1891 with 32 students in Old Main, the first building constructed on campus, and still in use to this day.[2]
Because there were no high schools in Arizona Territory, the University maintained separate preparatory classes for the first 23 years of operation.
The main campus sits on 380 acres (1.5 km2) in central Tucson, about one mile (1.6 km) northeast of downtown. There are 179 buildings on the main campus. Many of the early buildings, including the Arizona State Museum buildings (one of them the 1927 main library) and Centennial Hall, were designed by Roy Place, a prominent Tucson architect. It was Place''''''''''''''''s use of red brick that set the tone for the red brick facades that are a basic and ubiquitous part of nearly all UA buildings, even those built in recent decades. Indeed, almost every UA building has red brick as a major component of the design, or at the very least, a stylistic accent to harmonize it with the other buildings on campus. [3][4]
The campus is roughly divided into quadrants. The north and south sides of campus are delineated by a grassy expanse called the Mall, which stretches from Old Main eastward to the campus'''''''''''''''' eastern border at Campbell Avenue (a major north-south arterial street). The west and east sides of campus are separated roughly by Highland Avenue and the Student Union Memorial Center (see below).
The science and mathematics buildings tend to be clustered in the southwest quadrant; the intercollegiate athletics facilities to the southeast; the arts and humanities buildings to the northwest (with the dance department being a major exception as its main facilities are far to the east end of campus), with the engineering buildings in the north central area. The optical and space sciences buildings are clustered on the east side of campus near the sports stadiums and the (1976) main library.
Speedway Boulevard, one of Tucson''''''''''''''''s primary east-west arterial streets, traditionally defined the northern boundary of campus but since the 1980s, several university buildings have been constructed north of this street, expanding into a neighborhood traditionally filled with apartment complexes and single-family homes. The University has purchased a handful of these apartment complexes for student housing in recent years. Sixth Street typically defines the southern boundary, with single-family homes (many of which are rented out to students) south of this street.
Park Avenue has traditionally defined the western boundary of campus, and there is a stone wall which runs along a large portion of the east side of the street, leading to the old Main Gate, and into the driveway leading to Old Main.
Along or adjacent to all of these major streets are a wide variety of retail facilities serving the student, faculty and staff population: shops, bookstores, bars, banks, credit unions, coffeehouses and major chain fast-food restaurants such as Burger King and Chick-fil-A. The area near University Boulevard and Park Avenue, near the Main Gate, has long been a major center of such retail activity; many of the shops have been renovated since the late 1990s and a nine-story Marriott hotel was built in this immediate district in 1996.
The oldest campus buildings are located west of Old Main. Most of the buildings east of Old Main date from the 1940s to the 1980s, with a few recent buildings constructed in the years since 1990.
The Student Union Memorial Center, located on the north side of the Mall east of Old Main, was completely reconstructed between 2000 and 2003, replacing a 270,000-square-foot (25,000 m2) structure originally opened in 1951 (with additions in the 1960s). The new $60 million student union has 405,000 square feet (37,600 m2) of space on four levels, including 14 restaurants (including a food court with such national chains as Burger King, Panda Express, Papa John''''''''''''''''s Pizza and Chick-fil-A), a new two-level bookstore (that includes a counter for Clinique merchandise as well as an office supplies section sponsored by Staples with many of the same Staples-branded items found in their regular stores), 23 meeting rooms, eight lounge areas (including one dedicated to the USS Arizona), a computer lab, a U.S. Post Office, a copy center named Fast Copy, and a video arcade.

Much of the main campus has been designated an arboretum. Plants from around the world are labeled along a self-guided plant walk. The Krutch Cactus Garden includes the tallest Boojum tree in the state of Arizona.[6] (The university also manages Boyce Thompson Arboretum State Park, located c. 85 miles (137 km) north of the main campus.)
Two herbaria are located on the University campus and both are referred to as &quot;ARIZ&quot; in the Index Herbariorum

The University of Arizona Poetry Center
The Stevie Eller Dance Theatre, opened in 2003 (across the Mall from McKale Center) as a 28,600-square-foot (2,660 m2) dedicated performance venue for the UA''''''''''''''''s dance program, one of the most highly regarded university dance departments in the United States. Designed by Gould Evans, a Phoenix-based architectural firm, the theatre was awarded the 2003 Citation Award from the American Institute of Architects, Arizona Chapter. [7]
The football stadium has the Navajo-Pinal-Sierra dormitory in it. The dorm rooms are underneath the seats along the South and East sides of the stadium.

Academic departments and programs are organized into colleges and schools. Typically, schools are largely independent or separately important from their parent college. In addition, not all schools are a part of a college. The university maintains a current list of colleges and schools at <a href="http://www.arizona.edu/index/colleges.php">www.arizona.edu/index/colleges.php</a>. [10]
[edit] Admissions
The UA is considered a &quot;selective&quot; university by U.S. News and World Report.[11] In the fall semester of 2007, the UA matriculated 6,569 freshmen, out of 16,853 freshmen admitted, from an application pool of 21,199 applicants. The average person admitted to the university as a freshman in fall 2007 had a weighted GPA of 3.31 and an average score of 1102 out of 1600 on the SAT admissions test. Sixty-nine of these freshman students were National Merit Scholars.[12]
UA students hail from all states in the U.S. While nearly 72% of students are from Arizona, nearly 10% are from California, followed by a significant student presence from Illinois, Texas, Washington, and New York (2007).[13] The UA has over 2,200 international students representing 122 countries. International students comprise approximately 6% of the total enrollment at UA.[13]

In 2005, the Association of Research Libraries, in its &quot;Ranked Lists for Institutions for 2005&quot; (the most recent year available), ranked the UA libraries as the 33rd overall university library in North America (out of 113) based on various statistical measures of quality; this is one rank below the library of Duke University, one rank ahead of that of Northwestern University[24] (both these schools are members, along with the UA, of the Association of American Universities).
As of 2006, the UA''''''''''''''''s library system contains nearly five million volumes.
The Main Library, opened in 1976, serves as the library system''''''''''''''''s reference, periodical, and administrative center; most of the main collections and special collections are housed here as well. The Main Library is located on the southeast quadrant of campus near McKale Center and Arizona Stadium.
In 2002, a $20 million, 100,000-square-foot (10,000 m2) addition, the Integrated Learning Center (ILC), was completed; it is a home base for first-year students (especially those undecided on a major) which features classrooms, auditoriums, a courtyard with an alcove for vending machines, and a greatly expanded computer lab (the Information Commons) with several dozen Gateway and Apple Macintosh G5 workstations (these computers are available for use by the general public (with some restrictions) as well as by UA students, faculty and staff). Much of the ILC was constructed underground, underneath the east end of the Mall; the ILC connects to the basement floor of the Main Library through the Information Commons. As part of the project, additional new office space for the Library was constructed on the existing fifth floor.
The Science and Engineering Library is in a nearby building from the 1960s that houses volumes and periodicals from those fields. The Music Building (on the northwest quadrant of campus where many of the fine arts disciplines are clustered) houses the Fine Arts Library, including reference collections for architecture, music (including sheet music, recordings and listening stations), and photography. There is a small library at the Center for Creative Photography, also in the fine arts complex, devoted to the art and science of photography. The Law Library is in the law building.
The libraries at University of Arizona are expecting a 15 percent budget cut for the 2009 fiscal year. They will begin to explore the possibilities of cutting staff, cutting online modules, and closing some libraries. The biggest threat is the possible closure of 11 libraries. The staff is projected to decline from 180 employees to 155 employees. They also intend to cut face-face instructional program that teaches students in English 101 and 102 how to navigate the library. This will now be taught online.
[edit] Athletics
Main article: Arizona Wildcats
Like many large public universities in the U.S., sports are a major activity on campus, and receive a large operating budget. Arizona''''''''''''''''s athletic teams are nicknamed the Wildcats, a name derived from a 1914 football game with then California champions Occidental College, where the L.A. Times asserted that, &quot;the Arizona men showed the fight of wildcats.&quot;[25] The University of Arizona participates in the NCAA''''''''''''''''s Division I-A in the Pacific-10 Conference, which it joined in 1978.
[edit] Men''''''''''''''''s basketball
Main article: Arizona Wildcats men''''''''''''''''s basketball
The men''''''''''''''''s basketball team has been one of the nation''''''''''''''''s most successful programs since Lute Olson was hired as head coach in 1983, and is still known as a national powerhouse in Division I men''''''''''''''''s basketball.[26] As of 2009, the team has reached the NCAA Tournament 25 consecutive years, which is the longest active and second-longest streak in NCAA history (University of North Carolina at Chapel Hill had the longest streak with 27).[27] The Wildcats have reached the Final Four of the NCAA tournament in 1988, 1994, 1997, and 2001. In 1997, Arizona defeated the University of Kentucky, the defending national champions, to win the NCAA National Championship (NCAA Men''''''''''''''''s Division I Basketball Championship) by a score of 84–79 in overtime; Arizona''''''''''''''''s first national championship victory. The 1997 championship team became the first and only in NCAA history to defeat three number-one seeds en route to a national title (Kansas, North Carolina and Kentucky -- the North Carolina game being the final game for longtime UNC head coach Dean Smith). Point guard Miles Simon was chosen as 1997 Final Four MVP (Simon was also an assistant coach under Olson from 2005–08). The Cats also boast the third highest winning percentage over the last twenty years. Arizona has won a total of 21 conference championships in its'''''''''''''''' programs history.
The Wildcats play their home games at the McKale Center in Tucson. A number of former Wildcats have gone on to pursue successful professional NBA careers (especially during the Lute Olson era), including Gilbert Arenas, Richard Jefferson, Mike Bibby, Jason Terry, Sean Elliott, Damon Stoudamire, Luke Walton, Hassan Adams, Salim Stoudamire, Andre Iguodala, Channing Frye, Brian Williams (later known as Bison Dele), Sean Rooks, Jud Buechler, Michael Dickerson and Steve Kerr. Kenny Lofton, now best known as a former Major League Baseball star, was a four year letter winner as a Wildcat basketball player (and was on the 1988 Final Four team), before one year on the Arizona baseball team. Another notable former Wildcat basketball player is Eugene Edgerson, who played on the 1997 and 2001 Final Four squads, and is currently one of the primary stars of the Harlem Globetrotters as &quot;Wildkat&quot; Edgerson.
Before Lute Olson''''''''''''''''s hire in 1983, Arizona was the first major Division I school to hire an African American head coach in Fred Snowden, in 1972. After a 25-year tenure as Arizona head coach, Olson announced his retirement from the Arizona basketball program in October 2008. After two seasons of using interim coaches, Arizona named Sean Miller, head coach at Xavier University, as its new head basketball coach in April 2009.
The football team began at The University of Arizona in 1899 under the nickname &quot;Varsity&quot; (a name kept until the 1914 season when the team was deemed the &quot;Wildcats&quot;).[28]
The football team was notably successful in the 1990s, under head coach Dick Tomey; his &quot;Desert Swarm&quot; defense was characterized by tough, hard-nosed tactics. In 1993, the team had its first 10-win season and beat the University of Miami Hurricanes in the Fiesta Bowl by a score of 29–0. It was the bowl game''''''''''''''''s only shutout in its then 23-year history. In 1998, the team posted a school-record 12–1 season and made the Holiday Bowl in which it defeated the Nebraska Cornhuskers. Arizona ended that season ranked 4th nationally in the coaches and API poll. The 1998 Holiday Bowl was televised on ESPN and set the now-surpassed record of being the most watched of any bowl game in that network''''''''''''''''s history (the current record belongs to the 2005 Alamo Bowl between Michigan and Nebraska). The program is led by Mike Stoops, brother of Bob Stoops, the head football coach at the University of Oklahoma.
[edit] Baseball
Main article: Arizona Wildcats baseball
The baseball team had its first season in 1904. The baseball team has captured three national championship titles in 1976, 1980, and 1986, all coached by Jerry Kindall. Arizona baseball teams have appeared in the NCAA National Championship title series a total of six times, including 1956, 1959, 1963, 1976, 1980, and 1986 (College World Series). The team is currently coached by Andy Lopez; aided by Assistant Coach Mark Wasikowski, Assistant Coach Jeff Casper and Volunteer Assistant Coach Keith Francis. Arizona baseball also has a student section named The Hot Corner. Famous UA baseball alums include current Boston Red Sox manager Terry Francona, Cleveland Indian Kenny Lofton, Yankee Shelley Duncan, Brewers closer Trevor Hoffman, Diamondbacks third-base coach Chip Hale, former 12-year MLB pitcher and current minor league coach Craig Lefferts, longtime MLB standout J. T. Snow, star MLB pitchers Don Lee, Carl Thomas, Mike Paul, Dan Schneider, Rich Hinton and Ed Vosberg, NY Giants slugger Hank Leiber, Yankee catcher Ron Hassey, and Red Sox coach Brad Mills. Former Angels and Cardinals (among others) pitcher Joe Magrane is also a UA alum.
[edit] Softball
The Arizona softball team is among the top programs in the country and a perennial powerhouse. The softball team has won eight NCAA Women''''''''''''''''s College World Series titles, in 1991, 1993, 1994, 1996, 1997, 2001, 2006 and 2007 under head coach Mike Candrea (NCAA Softball Championship). Arizona defeated the University of Tennessee in the 2007 National Championship series in Oklahoma City. The team has appeared in the NCAA National Championship in 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 2001, 2002, 2006, and 2007 (a feat second only to UCLA), and has reached the College World Series 19 of the past 20 years. Coach Candrea, along with former Arizona pitcher Jennie Finch, led the 2004 U.S. Olympic softball team to a gold medal in Athens, Greece. The Wildcat softball team plays at Rita Hillenbrand Memorial Stadium.
[edit] Men''''''''''''''''s and women''''''''''''''''s golf
The university''''''''''''''''s golf teams have also been notably successful. The men''''''''''''''''s team won a national championship in 1992 (NCAA Division I Men''''''''''''''''s Golf Championships), while the women''''''''''''''''s team won national championships in 1996 and 2000 (NCAA Women''''''''''''''''s Golf Championship).
A strong athletic rivalry exists between the University of Arizona and Arizona State University located in Tempe. The UA leads the all-time record against ASU in men''''''''''''''''s basketball (138-73), football (44–35–1), and baseball (224–189–1) as of January 2006. The football rivalry game between the schools is known as &quot;The Duel in the Desert.&quot; The trophy awarded after each game, the Territorial Cup, is the nation''''''''''''''''s oldest rivalry trophy, distinguished by the NCAA. Rivalries have also been created with other Pac-10 teams, especially University of California, Los Angeles which has provided a worthy softball rival and was Arizona''''''''''''''''s main basketball rival in the early and mid-1990s.
[edit] Mascot
The University mascot is an anthropomorphized wildcat named Wilbur. The identity of Wilbur is kept secret through the year as the mascot appears only in costume. In 1986, Wilbur married his longtime wildcat girlfriend, Wilma. Together, Wilbur and Wilma appear along with the cheerleading squad at most Wildcat sporting events.[29] Wilbur was originally created by Bob White as a cartoon character in the University''''''''''''''''s humor magazine, Kitty Kat. From 1915 through the 1950s the school mascot was a live bobcat, a species known locally as a wildcat. This succession of live mascots were known by the common name of Rufus Arizona, originally named after Rufus von Kleinsmid, president of the university from 1914 to 1921. 1959 marked the creation of the first incarnated Wilbur, when University student John Paquette and his roommate, Dick Heller, came up with idea of creating a costume for a student to wear. Ed Stuckenhoff was chosen to wear the costume at the homecoming game in 1959 against Texas Tech and since then it has become a long-standing tradition. Wilbur will celebrate his 50th birthday in November 2009.
Officially implemented in 2003, Zona Zoo is the official student section and student ticketing program for the University of Arizona Athletics. The Zona Zoo program is co-owned by the Associated Students of the University of Arizona (ASUA) and Arizona Athletics, the program is run by a team of spirited individuals called the Zona Zoo Crew. Zona Zoo is one of the largest and most spirited student sections in NCAA Division I Athletics.
Notable venues
McKale Center, opened in 1973, is currently used by men''''''''''''''''s and women''''''''''''''''s basketball, women''''''''''''''''s gymnastics, and women''''''''''''''''s volleyball. The official capacity has changed often. The largest crowd to see a game in McKale was 15,176 in 1976 for a game against the University of New Mexico, a main rival during that period. In 2000, the floor in McKale was dubbed Lute Olson Court, for the basketball program''''''''''''''''s winningest coach. During a memorial service in 2001 for Lute''''''''''''''''s wife, Bobbi, who died after a battle with ovarian cancer, the floor was renamed Lute and Bobbi Olson Court. In addition to the playing surface, McKale Center is host to the offices of the UA athletic department. McKale Center is named after J.F. Pop McKale, who was athletic director and coach from 1914 through 1957. Joe Cavaleri (&quot;The Ooh-Aah Man&quot;) made his dramatic and inspiring appearances there.
Arizona Stadium, built in 1928 and last expanded in 1976, seats over 56,000 patrons. It hosts American football games and has also been used for university graduations. The turf is bermuda grass, taken from the local Tucson National Golf Club. Arizona football''''''''''''''''s home record is 258-139-12. The largest crowd ever in Arizona Stadium was 59,920 in 1996 for a game against Arizona State University.
Jerry Kindall Field at Frank Sancet Stadium hosts baseball games.
Rita Hillenbrand Memorial Stadium hosts softball games.

+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
When, towards late 1945, the Einheits-Chassis for the German combat tanks (the "E" series of medium and heavy tanks) reached the front lines, several heavily armed anti-aircraft turrets had been developed, including the 30mm Kugelblitz, based on the outdated Panzer IV, the "Coelian" turret with various armament options for the Panzer V Panther hull, and there were twin 55 mm as well as single and even 88mm cannon systems for the new E-50, E-75 and E-100 chassis'.
With these new weapons for medium- and high-altitude targets, Firepower was considerably increased, but the tank crews still had to rely on traditional visual tracking and aiming of targets. One potential solution in which the German Heeresleitung was highly interested from the start was the use of the Luftwaffe’s new radar technology for early target identification and as an aiming aid in poor weather conditions or even at night. The German Luftwaffe first introduced an airborne interception radar in 1942, but these systems were bulky and relied upon large bipolar antenna arrays. These were not suitable for any use in a ground vehicle, lest to say in a tank that would also carry weapons and ammunition.
A potential solution appeared in late 1944 with the development of the FuG 240 "Berlin". It was an airborne interception radar, too, but it was the first German radar to be based on the cavity magnetron, which eliminated the need for the large multiple dipole-based antenna arrays seen on earlier radars, thereby greatly increasing the performance of the night fighters. The FuG 240 with a rotating dish antenna was introduced by Telefunken in April 1945, primarily in Junkers Ju 88G-6 night-fighters, behind a plywood radome which considerably improved aerodynamics. This so greatly reduced drag compared to the late-model Lichtenstein and Neptun systems that the fighters regained their pre-radar speeds and made them competitive again. The FuG 240 was effective against bomber-sized targets at distances of up to 9 kilometers (5.5 mi), or down to 0.5 kilometer, which eliminated the need for a second, short-range radar system.
Right before the FuG 240's roll-out with the Luftwaffe, the Heer insisted on a ground-based derivative for its anti-aircraft units. Political pressure from Berlin convinced the RLM to share the new technology, and Telefunken was ushered to adapt the radar system to an armored ground vehicle in February 1945.
It soon became clear that the FuG 240 had several drawbacks for this task. On one side, ground clutter and the natural horizon limited the system's range and low-level effectiveness, but its 9 km range in free space made high altitude surveillance possible – just enough for the effective interception of Allied bombers that attacked important point targets. Furthermore, the whole system, together with its power supply and a dirigible dish antenna, took up a lot of space, so that its integration into a tank-based anti-aircraft vehicle like an SPAAG as an autonomous, stand-alone solution was ruled out.
A workable solution eventually came as a technical and tactical compromise: the army’s anti-aircraft tanks were to be grouped together in so-called Panzer-Fla-Züge, which consisted of several (typically four) SPAAGs and an additional, dedicated radar surveillance and command unit, so that the radar could guide the tank crews towards incoming targets – even though the gun crews still had to rely on visual targeting.
Two respective guidance vehicles developed, a light and a heavy one. The light one, intended against low-flying targets like the Ilyushin Il-2 on the Eastern front, became the 8x8 Funkmess-/Flak-Kommandowagen Sd.Kfz. 234/6. The heavy variant, with a bigger antenna and a more powerful emitter, became the Mittlerer Funkmess-/Flak-Kommandopanzer Sd.Kfz. 282. In contrast to the light and compact Sd.Kfz. 234/6, the Sd.Kfz. 282’s complete radar and observation system was installed in a new turret, so that it could be simply mounted onto the new E-50 Einheitspanzer battle tank hull.
This new, box-shaped turret had been developed by Rheinmetall, together with Telefunken, and was based on the turret design for the new 55 mm twin anti-aircraft cannon. It had a maximum armor of 60mm at the front and held all of the radar equipment, christened "Basilisk", after the monster from medieval mythology with a petrifying sight. The turret held a crew of three: a commander, a radar operator, and an observer for the optical rangefinder. The rest of the crew, the driver and a radio operator, sat in the hull. No armament was fitted, even though a light machine gun could be mounted on the roof for self-defense, even though it could not be operated from the inside. A heavier armament was not deemed necessary since the vehicle would stay close to the heavily armed tanks/SPAAGs it would typically accompany.
The Basilisk radar’s rotating dish antenna had a diameter of 90 cm (35 ½ inches) and was installed at the turret's front under a hard vinyl cover. Power of the modified FuG 240 was 25kW, with a search angle of +80/− 5° and a frequency range: 3,250–3,330MHz (~10 cm). Range was, due the bigger antenna and a higher emitter output, increased to 0.5–11.0 kilometer, even though only under ideal conditions. Power came from a dedicated generator that was connected to the E-50’s V-12 Maybach HL 234 gasoline engine.
Beyond the radar system, the vehicle was furthermore equipped with a powerful visual coincidence range finder in the turret, combined with an analogue computer, the Kommandogerät (KDO) 40 Telemeter. This system had been introduced in 1941 as a guidance tool for stationary anti-aircraft units equipped with the 88 mm and the 105 mm Flak, but it had so far – due to its size and bulk – only been deployed on an unarmored trailer
The KDO 40 and similar sights worked as follows: Light from the target entered the range finder through two windows located at either end of the instrument. At either side, the incident beam was reflected to the center of the optical bar by a pentaprism, and this optical bar was ideally made from a material with a low coefficient of thermal expansion so that optical path lengths would not change significantly with temperature. The reflected beam first passed through an objective lens and was then merged with the beam of the opposing side with an ocular prism sub-assembly to form two images of the target which were viewed by the observer through the eyepiece. Since either beam entered the instrument at a slightly different angle the resulting image, if unaltered, would appear blurry. Therefore, in one arm of the instrument, a compensator was integrated which could be adjusted by the operator to tilt the beam until the two images matched. At this point, the images were said to be in coincidence. The degree of rotation of the compensator determined the range to the target by simple triangulation, allowing the calculation of the distance to the observed object.
Fixed target reading with the device mounted in the Sd.Kfz. 282 turret was possible on targets from 3,000 to 20,000 m. Aerial courses could be recorded at all levels of flight and at a slant range between 4,000 and 18,000 m - enough for visual identification beyond an anti-aircraft group's effective gun ranges and perfectly suitable for long range observation, so that the Sd.Kfz. 282 also had excellent reconnaissance and observation capabilities. The rangefinder’s optical bar had a massive span of 400 cm (157.5 in) and went right through the turret, just above the radar device installation. The whole device, together with its armored fairing, was 4,60 m (15 ft 1 in) wide, so that it protruded from the turret on both sides over the lower hull. The odd and unwieldy installation quickly earned the vehicle nicknames like "Hirsch (stag)", "Zwo-Ender" (a young stag with just two antlers) or “Ameise” (ant). None of these were official, though. In order to protect the Telemeter on the way, the turret was normally turned by 90° and hidden under a tarpaulin, in order not to give away any details of the highly classified equipment.
However, development of the Einheitspanzer family lagged behind schedule, and in early 1945 no E-50 chassis was available for the highly specialized Sd.Kfz. 282 – battle tanks and SPGs were in higher demand. As an alternative, the turret was quickly adapted for different tank hulls, namely the Sd.Kfz. 171, the Panzer V ‘Panther’ medium tank and the heavy Sd.Kfz. 181 ‘Tiger I’. Tests with both hulls in spring 1945 were successful, but only the lighter ‘Panther’ hull was chosen because it was lighter overall, more mobile and available in sufficient numbers for a quick roll-out. In this configuration, the system received the designation Sd.Kfz. 282/1, while the original Sd.Kfz. 282 designation was reserved for the originally planned E-50 chassis variant.
The first vehicles reached, together with the new FlaK tanks, the front units in September 1945. Operating independently, they were primarily allocated to the defense of important production sites and the city of Berlin, and they supported tank divisions through early warning duties and visual long-range reconnaissance. Operationally, the Sd.Kfz. 282’s sensor setup with its combined visual and radar input turned out to be surprisingly successful. The combination of the Basilisk radar with the KDO 40 rangefinder allowed a time from initial target acquisition to the first AA shot of less than 20 seconds, which was impressive for the time – typically, simple visual target acquisition took 30 seconds or more. First shot hit probability was appreciably improved, too, and even quick passes of aircraft at low altitudes could be precalculated, if the radar was not obstructed.
However, the radar remained capricious, its performance rather limited and the unarmored antenna fairing at the turret’s front was easily damaged in combat, even by heavy machinegun fire. But the Sd.Kfz. 282 offered, when the vehicle was placed in a location with a relatively free field of view (e. g. on a wide forest clearance or in an open field), a sufficient early warning performance against incoming bombers at medium to high altitudes, and it also appreciably mobilized the bulky but valuable KDO 40 device. It now could easily be moved around and keep up with the pace of motorized battle groups that the Panzer-Fla-Züge units were supposed to protect.
Until the end of hostilities, probably thirty Sd.Kfz. 282/1s were completed from newly built (Ausf. F, recognizable through the simpler all-metal wheels) or from refurbished earlier Panzer V chassis of various types before production switched in early 1946 to the E-50 chassis which had eventually become available in sufficient numbers.

The kit and its assembly:
Another submission to the “Recce & Surveillance” group build at whatifmodellers.com in July 2021, and actually a good occasion to tackle a project that I had on my list for some years. A long while ago I bought a resin conversion set with a (purely fictional) Heer ‘46 anti-aircraft surveillance radar system, based on an E-50 chassis. Unfortunately, I cannot identify the manufacturer, but this 1:72 conversion set was/is nicely molded, with delicate details, no bubbles or flash and it even came with a commander figure for an optional open hatch on top as well as a pair of delicate brass antennae.
Even though I could have mounted this replacement turret onto a Trumpeter or Modelcollect E-50/75 chassis, I rather decided to create an earlier (1945 time frame) interim vehicle on a late Panzer V ‘Panther’ basis, mostly because it would be more compact and I doubt that brand new E-50/75s would have been “wasted” on second line/support vehicles like this mobile surveillance/commando post for anti-aircraft units?
The Panther chassis is the old Hasegawa kit for an Ausf. G tank from 1973, chosen because of its good fit, simplicity and the vinyl tracks, which I prefer. However, the kit clearly shows its age and some weak/soft details (e. g. the gratings on the engine deck), but it was enough for my plans and easy to handle.
Both turret and hull were built separately and basically OOB, combined with an adjusted turret ring. The Kdo 40’s “antlers” are to be glued directly to the turret’s flanks, but I reinforced the connections with wire. I also replaced the set’s brass antennae with heated sprue material and used a surplus PE detail set from a Modelcollect E-50/75 to hide the crude engine openings and change the overall look of the Panther a little. Some storage boxes as well as spare track links were added to the flanks, stuff collected from the scrap box.
To emphasize the refurbished character of the vehicle I left away the Panther’s side skirts – these were easily lost in battle, anyway, and probably have rather been allocated to battle tanks than to 2nd line support vehicles, despite leaving the Panther’s lower hull under the mudguards vulnerable.
Painting and markings:
Even though the paint scheme on this model is based on German standard colors, it is a little special. Late in real-world WWII some Panzer Vs received a unique, uniform RAL 6003 (Olivgrün) factory finish instead of the usual all-over RAL 7028 (Dunkelgelb) or the bare oxide red primer finish, onto which the frontline units would add individual camouflage, depending on the theatre of operations and whatever paint or application tool was at hand. This special green livery was adopted for the model, including the new turret. The individual camouflage consists of diagonal stripes in Dunkelgelb and Rotbraun (RAL 8017), added on top of the green basis with rather sharp and straight edges and only to the vertical surfaces. The practice to leave out the horizontal surfaces was called “Sparanstrich” (literally “economy paintwork”), an attempt to save the more and more scarce paint.
This rather odd style was actually applied to several late war Panther tanks – even though I am personally not certain about this pattern’s effectiveness? Maybe a kind of dazzle effect was sought for?
The basic green became a modern-day RAL 6003 from the rattle can (which is very close to FS 34102, just a tad lighter), applied in a rather cloudy fashion on top of an initial coat of Oxide Red primer (RAL 3009) overall, also from the rattle can. On top of that the stripes were painted with a brush, partly masked but mostly free-handedly. For some variation I used this time Tamiya XF-60 (a rather pale interpretation of Dunkelgelb which IMHO lacks a greenish hue and rather looks like a desert sand tone) and XF-64 (a rich whole milk chocolate tone) to create the additional camouflage, not fully opaque so that the impression of thinly/hastily applied paint was reinforced.
Once dry, the whole surface received a very dark brown washing with thinned acrylic paint and surface details were emphasized through dry-brushing with earth brown and beige.
For a different look (and to break up the tank’s bulky outlines) I applied camouflage nets to the model, realized with gauze bandages drenched in Tamyia XF-62 (Olive Drab) and mounted into place around the turret and at the front of the hull while still slightly wet.
Decals were puzzled together from various German tank sheets. The kit was sealed with matt acrylic varnish, what also fixed the cammo nets in place. The originally shiny black vinyl tracks were also painted/weathered, with a wet-in-wet mix of grey, iron, black and red brown (all acrylics). Once mounted into place, mud and dust were simulated around the running gear and the lower hull with a greyish-brown mix of artist mineral pigments.
Not a spectacular build, but I am happy that I eventually had the opportunity and motivation to tackle this project that had been lingering for years in the The Stash™. The result looks really good – the anonymous resin set is/was excellent, and combined with the Panther hull, the whole thing looks very credible. I am only a bit sad that the odd, almost artistic camouflage got a little lost under the cammo nets and the equipment on the hull, and the dust/dirt on the lower areas blurs the three basic colors even more. Well, you cannot have everything at once, and I might re-use this scheme on a “cleaner” future build.

Some background:
The Flakpanzer Coelian comprised a family of self-propelled anti-aircraft gun tanks, designed by Rheinmetall during World War II for the German armed forces. In the first years of the war, the Wehrmacht had only little interest in developing self-propelled anti-aircraft guns, but as the Allies developed air superiority, the need for more mobile and better-armed self-propelled anti-aircraft guns increased.
As a stopgap solution the Wehrmacht had adapted a variety of wheeled, half-track and tracked vehicles to serve as mobile forward air defense positions to protect armor and infantry units in the field as well as for temporary forward area positions such as mobile headquarters and logistic points. As Allied fighter bombers and other ground attack aircraft moved from machine gun armament and bombing to air-to-ground rockets, the air defense positions were even more vulnerable. The answer was to adapt a tank chassis with a specialized turret that would protect the gun crews while they fired upon approaching Allied aircraft.
Initial AA-tank designs were the ‘Möbelwagen’ and the ‘Wirbelwind’, effectively both conversions of refurbished Panzer IV combat tank chassis’ with open platforms or open turrets with four 20mm cannon. Alternatively, a single 37mm AA gun was mounted, too, resulting in the more effective ‘Ostwind’ tank – but all these vehicles were just compromises and suffered from light armor and lack of crew protection.
Further developments led to the ‘Kugelblitz’, another Panzer IV variant, but this time the ball-shaped turret was effectively integrated into the hull, resulting in a low silhouette and a fully protected crew. Another new feature was the use of the Mauser MK 103 machine cannon – a lightweight, belt-fed aircraft gun with a gas-powered action mechanism, first employed on board of the Hs 129 attack aircraft against ground targets, including tanks. The Mk 103 had a weight of only 141 kg (311 lb) and a length of 235 cm (93 in) (with muzzle brake). Barrel length was 134 cm (53 in), resulting in Kaliber L/44.7 (44.7 calibres).
Anyway, the Kugelblitz could only mount two of these guns in its very cramped and complicated tilting turret. Venting and ammunition feed problems could also not be solved, so that the innovative vehicle never made it beyond the prototype and evaluation stage, even though the integration of the Kugelblitz turret into the hull of the Jagdpanzer ‘Hetzer’ was considered for some time.
In parallel, the promising MK 103 was also tested in the four-gun carriage of the Wirlbelwind’s 20 mm Flakvierling 38 mount, resulting in the ‘3 cm Flakvierling 103/38’ and the respective ‘Zerstörer 45’ tank prototype. But this was, effectively, only a juiced up version of the obsolete ‘Wirbelwind’, again with only a roofless and vulnerable turret and the obsolete Panzer IV as base. The ‘Zerstörer 45’ was consequently rejected, but the firepower of the four guns was immense: Rate of fire of a single MK 103 was 400 - 450 RPM, and the rounds carried three times as much explosive charge as a Soviet 37 mm round. Both HE/M and APCR rounds were available for the MK 103. Muzzle velocity was 860-940 m/sec, paired with a high degree of accuracy. The armor penetration for APCR was 42–52 mm (1.7–2.0 in) / 60° / 300 m (980 ft) or 75–95 mm (3.0–3.7 in) / 90° / 300 m (980 ft) – more than enough for aircraft, and even dangerous for many combat tanks when hitting more lightly armored areas. Anyway, it was not possible to combine four of these 30mm guns with a favorably shaped, completely enclosed turret for an effective front line anti-aircraft tank that could stand its own among the armored combat units.
The solution to this problem eventually materialized in 1943 with the decision to completely abandon the limiting Panzer IV chassis and build a new generation of anti-aircraft tanks on the basis of the larger (and heavier) Panzer V medium battle tank, the ‘Panther’. Its chassis had in the meantime become available in considerably numbers from damaged and/or recovered combat tanks, and updated details like new turrets or different wheels were gradually introduced into production and during refurbishments.
The Panther could mount a considerably larger and heavier turret than the previous standard tank chassis like the Panzer III and IV, and this potential was full exploited – as well as the possibility to increase the weapon system’s weight, thanks to the sturdier chassis. Rheinmetall’s new, fully enclosed, 360° rotating turret could carry a wide array of weapons and ammunition (all were belt-fed), a crew of three and also offered a good protection through a sloped, frontal armor of 70mm thickness. Traverse and elevation of the turret was hydraulic, allowing a full elevation in just over four seconds, and a 360° traverse in 15.5 seconds. The initial version was armed with two 3.7 cm FlaK 43 guns, as a compromise between range, firepower and rate of fire. Beyond this initial variant, Rheinmetall developed the ‘Coelian’ turret in various versions, too, including fully enclosed turrets with a single 55 mm gun and with four 20mm MG 151/20 guns.
Eventually, in May 1944, a complete family of turrets with different armament options was cleared for production: the standard Coelian I, with a revised mount for the twin 3.7 cm FlaK 43 guns, a heavier variant with twin 55 mm guns against larger, high-flying targets (Coelian II; the guns were based on another aircraft weapon, the MK 214), and finally the Coelian III with four Mk 103 cannon against low-flying attack aircraft and soft/lightly armored ground targets. The variant with four 20 mm guns had been dropped, since it did not offer and added value compared to the Coelian III. All these vehicles ran under the SdKfz. 171/3 designation, with suffixes (A-C) to distinguish their armament in a more or less standardized turret.
Even though ground-based, mobile radar systems were under development at that time, all these turrets had to rely only on optical sensors, even though very effective optical rangefinders were introduced. All the turrets of the Coelian family were to be mounted on revamped Panzer V chassis, simply replacing the former combat tank turrets (either the original production turret from the A, D and G variant or the newly introduced Schmalturm from the F version). Theoretically, they could have also been mounted onto the Panzer VI ‘Tiger’ chassis, but due to this type’s weight and complexity, this was not carried out.
However, the SdKfz. 171/3 Panther/Coelian family designation had in the meantime also just become an interim solution: Plans had been made to start the production of a completely new, simplified tank vehicle family, the so-called ‘Einheitspanzer’. The resulting standard combat tanks (called E-50 and E-75, based on their weight class in tonnes) and their respective hulls would be based on the large Königstiger battle tank, and potentially accept even bigger turrets and weapons. Consequentially, while production of the Coelian turrets and the conversion of 2nd hand and by the time also new Panther hulls of all variants was just gaining momentum in late 1944, work for the new Einheitspanzer tanks and their weaponry had already started.
Roundabout 300 Coelian tanks reached frontline units, two third of them were factory-built, and in the course of early 1945 the Coelian family had gradually replaced most of the outdated Panzer IV AA variants and SPAAGs with open turrets. The Coelian tanks were soon joined by the newly produced, dedicated Flakpanzer variants of the Einheitspanzer family, including a twin 55 mm gun on the E-50 chassis and also a monstrous 140 ton anti-aircraft variant of the heavy E-100 chassis, equipped with an automatic twin 8.8cm Flak in a fully enclosed and heavily armored turret.

The kit and its assembly:
This was a spontaneous build, in the wake of other recent whif tanks and using some leftover parts from the kit pile(s). Things started with a KORA 1:72 resin conversion kit with a 2x 37mm FlaK Coelian turret for a Panther chassis – but with broken and bent gun barrels. I had actually stashed the parts away for a potential mecha build/conversion, long ago, but while doing legwork for late German WWII tanks I recently came again across the various anti-aircraft tank designs. And I wondered if mounting the Coelian turret on a Panzer IV chassis would be possible and lead to a compact (and whiffy) new vehicle?
Well, it would not work, because the Coelian turret needs a considerably bigger turret bearing diameter than anything the Panzer IV hull could realistically handle (even the Panther’s Schmalturm is actually a little too wide…), and so I folded the idea up again and put it onto the “vague ideas” pile.
…until I stumbled upon the leftover hull from a Hasegawa Panther Ausf. F in the donor kits pile, which had originally given both of its OOB turrets (a Schmalturm and a standard model) to other conversions. While mating the Coelian turret with its originally intended hull was not a sexy project, I eventually did so, because I could effectively use two leftovers for something sound and well-balanced.
Concerning the assembly phase, there’s not much to tell about the Hasegawa Panther Ausf. F. Fit is good, a simple kit, and it comes, as a benefit, with optional all-steel wheels which I used for my conversion, changing the overall look to a true late war model. Only the opening for the turret had to be widened in order to accept the new resin turret.
The latter only consists of two parts: the massive core section and a separate weapon mount. The latter was in so far modified that I added a simple metal peg which can be switched between two holes in the turret hull, for two gun positions.
Since the original gun barrels had to be replaced, anyway, I did a thorough (and fictional) modification: I used four 1:48 20 mm brass barrels for a Flak 38 Flakvierling (from RB Models) and mounted them in two staggered pairs onto the original cannon fairing. The resulting gun array looks impressive and even realistic, and, thanks to the scale-o-rama effect, the 1:48 parts have the perfect size for 30 mm cannon barrels in 1:72!
Painting and markings:
Something “German”, but nothing spectacular, so I ended up with another variant of the Hinterhalt scheme, found on a Jagdpanther from the Ardennenoffensive period. In this case, the prominent colors are Dunkelgelb and Olivgrün in broad stripes, separated by blurred, thin lines made of Rotbraun.
As a little twist I wanted to modify the scheme in so far that this vehicle was to show its conversion heritage in a workshop, so hull and turret received different basic tones as an initial step.
The hull and all wheels were painted with matt RAL 7028 (a modern equivalent to the WWII Dunkelgelb), while the turret received a red primer coat with Oxidrot (RAL 3009). On top of these, wide green bands (RAL 6003 from Modelmaster) and separating russet (Humbrol 113) stripes were painted with brushes. In order to brighten up the relatively dark turret, some yellow mottles were added on the Oxidrot areas (using Revell 16).
Once dry, the whole surface received a sand paper treatment, so that the RAL 7028 would shine through here and there, as if worn out. After a dark brown wash, details were emphasized with dry-brushing in light grey and beige. Decals were puzzled together from various German tank sheets, and the kit finally sealed with matt acrylic varnish.
The black vinyl tracks were also painted/weathered, with a wet-in-wet mix of black, iron and red brown (all acrylics). Once they were mounted into place, mud and dust around the running gear and the lower hull was simulated with a greyish-brown mix of artist mineral pigments.
A bit of recycling and less exotic than originally hoped for – but it’s still a whiffy tank model, and its proximity to the real but unrealized Coelian project makes this one even more subtle. Pile reduction, one by one…
Norton Commando 928cc Norcil Mk III - 1975
Norton Commando
From Wikipedia, the free encyclopedia
The Norton Commando was the last twin piston-engined motorcycle produced by the Norton Motorcycle company. Their last production bikes used a twin-rotor Wankel engine.
During the ten years it was in production it was popular all over the world. In the United Kingdom it won the MCN "Machine of the Year" competition for five successive years from 1968-1972.[1]
Some regard it as the British Motorcycle Industry's swansong, selling well from its introduction in 1967 through the end of the British bike industry as a commercial concern in the mid 1970s.[2]
[edit] Background
The origins of the Norton Commando can be traced back to the late 1940s when the 497 cc Norton Model 7 Twin, designed by Bert Hopwood and initially an export only model. The twin cylinder design evolved into the 650 cc Norton Dominator and 750 cc Norton Atlas before being launched as the 750 cc Commando in 1967.[3]
[edit] Isolastic system
The revolutionary part of the Commando, compared to earlier Norton models, was the frame developed by former Rolls Royce engineer Dr. Stefan Bauer. He believed the classic Norton Featherbed frame design went against all engineering principles, so Bauer designed his frame around a single 2.25-inch (57 mm) top tube. He tried to free the Commando from classic twin vibration problems, which had severely increased as the volume of the basic engine design expanded from the 500 cc of Edward Turner's 1938 Triumph Speed Twin. Bauer, with Norton Villiers Chief Engineer Bernard Hooper and assistant Bob Trigg, decided that the engine, gearbox and swing-arm assembly were to be bolted together and isolated from the frame by special rubber mountings.[4] This eliminated the extreme vibration problems that were apparent in other models in the range, as it effectively separated the driver from the engine. Named the Isolastic anti-vibration system, the system's patent document listed Hooper as the lead inventor.[2] Although the Isolastic system did reduce vibration, maintaining the required free play in the engine mountings at the correct level was crucial to its success. Too little play brought the vibration back; too much, and the result was "interesting" handling.
[edit] Models
[edit] Mk1 750 cc
The Norton Commando was introduced in 1967 at the Earls Court Show. The first production machines completed in April 1968 had bending frame problems, removed with the introduction of a new frame in January 1969. The original model, called the 'Fastback' was joined by the production racer 'S Type' which had a high level left-side exhaust and a 2.5 gallon petrol tank.
Production of the machine was initially complex and located across different parts of England, with the engines produced in Wolverhampton, frames in Manchester, while components and final assembly was at Burrage Grove, Plumstead. In late 1968 Plumstead works was subject to a Greater London Council compulsory purchase order, and closed in July 1969. With assistance of a Government subsidy, the assembly line was moved to North Way, Andover; with the Test Department in an aircraft hangar on Thruxton Airfield. Frame manufacturing was transferred to Wolverhampton, where a second production line produced about 80 complete machines each week. Components and complete engines and gearboxes were also shipped overnight, from Wolverhampton to the Andover assembly line.
The production racer, featuring an OHV tuned engine, front disk brake and was finished in bright yellow - known as the 'Yellow Peril'. In March to June 1970 the updated S called the 'Roadster' had the 750 cc OHV engine, low-level exhaust, upward angled silencers with reverse cones. September 1970 saw the introduction of the classic 'Fastback Mk2', which had alloy levers with modified stands and chain guards. The ‘Street Scrambler’ and the ‘Hi Rider’ were launched in May 1971, with the ‘Fastback Long Range’ with increased petrol tank capacity from July 1971.
The ‘Combat’ engine was introduced in January 1972 saw the appearance of the ‘Mk4 Fastback’, updated ‘Roadster’ and the ‘750 Interstate’. The ‘Combat’ delivered 65 brake horsepower (48 kW) at 6500 rpm with a 10:1 compression ratio, but the stressed 750 cc twin proved extremely unreliable, with main bearing failures and broken pistons common.
The 'Combat' engine combined with quality control problems gave the company a bad reputation, which was highly covered in the press. By the middle of 1972 BSA Triumph group were in serious financial trouble. The UK Government decided to bail the company out with a financial rescue package, providing it would agree to merge with Norton Villiers. Norton Villiers Triumph was duly formed and the new company got off to a shaky start.
The last of the 750 series, the MkV was produced from November 1972 to mid-1973 as a 1973 model and featured improved crank bearings and the standard grind camshaft. Compression was reduced to 9.4:1.
[edit] Police
The police were showing a lot of interest in the Commando and so Neale Shilton was recruited from Triumph to produce a Commando to police specifications. The end result was the 'Interpol' machine, which sold well to police forces, both at home and abroad. The machine was powered by a 750 cc. O.H.V. engine and included panniers, top box, fairing, and had fittings for a radio and auxiliary equipment.
[edit] Mk2 850 cc
In January 1973 the ‘Mk.5 Fastback’ was launched and the ‘Long Range’ was discontinued, foreshadowing the first 850 cc machines launched in April 1973. The ‘Roadster’, ‘Hi Rider’ and the ‘Interstate’ all began to use a new 828 cc. engine, which had similar power to the 750 cc models but were less stressed.
1973 also saw the start of development on a new machine with a monocoque pressed steel frame, that also included a 500 cc twin, stepped piston engine called the 'Wulf'. However, as the Norton Villiers Triumph company was again in serious financial problems, development of the 'Wulf' was dropped in favour of the rotary Wankel type engine inherited from BSA.
In late 1973 redundancy notices were issued at Andover, followed by a sit-in at the works. The Conservative Government withdrew the subsidy in early 1974, restored by the Labour party post the general election. NVT resultantly decided to concentrate production of the Commando at Wolverhampton and Small Heath, causing unrest at Meriden which resulted in a workers’ sit in and stopping production at Small Heath. By the end of 1974 NVT had lost over £3 million.
However, the company still managed to produce new Commando models, with 1974 seeing the release of the Roadster based ‘JPN Replica’ and the ‘Mk.2a Interstate’.
[edit] Mk3 850 cc
The 850 cc MK3 Commando was launched in March 1975 and for the first time was fitted with an "electric starter" - better described as electric "assister", as it would soon drain the battery.[5] The range of models was reduced to just two machines, the ‘Mk.3 Interstate’ and the ‘Roadster’, both with a left side gear change, right foot brake and rear disk brake to comply with United States vehicle regulations. The specification remained unchanged until October 1977 when the last machines were made, although few 'Roadster's were made in the end due to the higher cash sales value of the Interstate.
In 1975 the Industry Minister recalled a loan for £4 million and refused to renew the company’s export credits. The company then went into receivership and redundancies were announced for all of the staff at the various sites. At Wolverhampton an action committee was formed in an effort to continue production and develop the ‘Wulf’ engine - but the works was closed anyway.
NVT was saved when the Small Heath/Meriden part of the company was subsidised by Industry Secretary Tony Benn as Industry Secretary, but this did not include Commando production. Ironically, the new company bought the gates from the now demolished Wolverhampton Tong Castle works, and erected them at the works entrance in Marston Road, Small Heath.[6]
[edit] Racing
Right from the beginning the Commando took part in racing events.
After successes in 1969 by dealer entered machines like Paul Smart's second and Mick Andrew's 4th places in the Isle of Man TT Production class and a win in the Hutchinson 100 Production Class by Mick Andrew on the Gus Kuhn entered Commando and 4th by Peter Williams' Arter Bros machine, the company decided to produce a racing model - hence the developed S and "Yellow Peril" models.
In partnership with John Player Special cigarettes from the early 1970s, Norton went factory racing.[7] Early entries were based on the Commando, and in 1973 Peter Williams won the 1973 Formula 750 Isle of Man TT, with Mick Grant second.
Racing continued until the collapse of Norton Villiers into BSA Triumph in 1973, and did not return until the Rotary engine Nortons of the 1980s.
[edit] Commando revival
In light of its "last of the classic British twins" tag, and the fact that many of the trade marks were disputed and patents expired, a number of new Norton companies began to emerge. These were based on production of new parts sourced from various manufacturers, and the legal battle over the Norton name between Germany (whose Norton was based on the Rotax 650 cc engine that powers the smaller BMW motorcycles), Canada and North America. Many used the Commando name for their lead model, or included the prospect of a Commando twin at a later date.
However, the most interesting development for original Commando fans was the development of re-manufactured original motorcycles. These mainly came from Norvil in the UK and two companies in the United States, Colorado Norton Works and Kenny Dreer's Vintage Rebuilds based in Portland, Oregon. From 1995 onwards Vintage Rebuilds began restoring vintage British and Italian motorcycles, with Dreer showing a "new" Commando based Norton VR880 Sprint Special in 1999 with newly cast and manufactured parts, but using a bored out 880 cc twin engine with some modern developments. Kenny Dreer progressed from restoring and upgrading Norton Commandos to producing whole machines. He modernised the design and in the early 2000s went into series production of the Commando 961 SS, which combined traditional Norton cafe racer styling with new technology including carbon fibre wheels to reduce weight and a chro-moly tubular steel frame.[8] Dreer was forced to suspend production in April 2006 following funding problems.[9]
[edit] New Commando in production
On 19th March 2010 Norton Motorcycles (UK) Ltd shipped the first new Norton Commando for over 30 years. As of mid April 2010 the Company was shipping 5 - 10 new machines per week. [10]
The ownership of the Norton brand passed into the hands of UK businessman and owner of Norton Racing Ltd. Stuart Garner who has formed Norton Motorcycles (UK) Ltd.. The Company has three models in the new range, a limited edition (200 unit) Commando 961 SE which has sold out, a Cafe Racer and a Sport model, all of which commenced shipping during April 2010. The new Norton has appeared in road tests in the British Motor Cycle News with favourable comments.

But this was, effectively, only a juiced up version of the obsolete ‘Wirbelwind’, again with only a roofless and vulnerable turret and the obsolete Panzer IV as base. The ‘Zerstörer 45’ was consequently rejected, but the firepower of the four guns was immense: Rate of fire of a single MK 103 was 400 - 450 RPM, and the rounds carried three times as much explosive charge as a Soviet 37 mm round. Both HE/M and APCR rounds were available for the MK 103. Muzzle velocity was 860-940 m/sec, paired with a high degree of accuracy. The armor penetration for APCR was 42–52 mm (1.7–2.0 in) / 60° / 300 m (980 ft) or 75–95 mm (3.0–3.7 in) / 90° / 300 m (980 ft) – more than enough for aircraft, and even dangerous for many combat tanks when hitting more lightly armored areas. Anyway, it was not possible to combine four of these 30mm guns with a favorably shaped, completely enclosed turret for an effective front line anti-aircraft tank that could stand its own among the armored combat units.
The solution to this problem eventually materialized in 1943 with the decision to completely abandon the limiting Panzer IV chassis and build a new generation of anti-aircraft tanks on the basis of the larger (and heavier) Panzer V medium battle tank, the ‘Panther’. Its chassis had in the meantime become available in considerably numbers from damaged and/or recovered combat tanks, and updated details like new turrets or different wheels were gradually introduced into production and during refurbishments.
The Panther could mount a considerably larger and heavier turret than the previous standard tank chassis like the Panzer III and IV, and this potential was full exploited – as well as the possibility to increase the weapon system’s weight, thanks to the sturdier chassis. Rheinmetall’s new, fully enclosed, 360° rotating turret could carry a wide array of weapons and ammunition (all were belt-fed), a crew of three and also offered a good protection through a sloped, frontal armor of 70mm thickness. Traverse and elevation of the turret was hydraulic, allowing a full elevation in just over four seconds, and a 360° traverse in 15.5 seconds. The initial version was armed with two 3.7 cm FlaK 43 guns, as a compromise between range, firepower and rate of fire. Beyond this initial variant, Rheinmetall developed the ‘Coelian’ turret in various versions, too, including fully enclosed turrets with a single 55 mm gun and with four 20mm MG 151/20 guns.
Eventually, in May 1944, a complete family of turrets with different armament options was cleared for production: the standard Coelian I, with a revised mount for the twin 3.7 cm FlaK 43 guns, a heavier variant with twin 55 mm guns against larger, high-flying targets (Coelian II; the guns were based on another aircraft weapon, the MK 214), and finally the Coelian III with four Mk 103 cannon against low-flying attack aircraft and soft/lightly armored ground targets. The variant with four 20 mm guns had been dropped, since it did not offer and added value compared to the Coelian III. All these vehicles ran under the SdKfz. 171/3 designation, with suffixes (A-C) to distinguish their armament in a more or less standardized turret.
Even though ground-based, mobile radar systems were under development at that time, all these turrets had to rely only on optical sensors, even though very effective optical rangefinders were introduced. All the turrets of the Coelian family were to be mounted on revamped Panzer V chassis, simply replacing the former combat tank turrets (either the original production turret from the A, D and G variant or the newly introduced Schmalturm from the F version). Theoretically, they could have also been mounted onto the Panzer VI ‘Tiger’ chassis, but due to this type’s weight and complexity, this was not carried out.
However, the SdKfz. 171/3 Panther/Coelian family designation had in the meantime also just become an interim solution: Plans had been made to start the production of a completely new, simplified tank vehicle family, the so-called ‘Einheitspanzer’. The resulting standard combat tanks (called E-50 and E-75, based on their weight class in tonnes) and their respective hulls would be based on the large Königstiger battle tank, and potentially accept even bigger turrets and weapons. Consequentially, while production of the Coelian turrets and the conversion of 2nd hand and by the time also new Panther hulls of all variants was just gaining momentum in late 1944, work for the new Einheitspanzer tanks and their weaponry had already started.
Roundabout 300 Coelian tanks reached frontline units, two third of them were factory-built, and in the course of early 1945 the Coelian family had gradually replaced most of the outdated Panzer IV AA variants and SPAAGs with open turrets. The Coelian tanks were soon joined by the newly produced, dedicated Flakpanzer variants of the Einheitspanzer family, including a twin 55 mm gun on the E-50 chassis and also a monstrous 140 ton anti-aircraft variant of the heavy E-100 chassis, equipped with an automatic twin 8.8cm Flak in a fully enclosed and heavily armored turret.

The kit and its assembly:
This was a spontaneous build, in the wake of other recent whif tanks and using some leftover parts from the kit pile(s). Things started with a KORA 1:72 resin conversion kit with a 2x 37mm FlaK Coelian turret for a Panther chassis – but with broken and bent gun barrels. I had actually stashed the parts away for a potential mecha build/conversion, long ago, but while doing legwork for late German WWII tanks I recently came again across the various anti-aircraft tank designs. And I wondered if mounting the Coelian turret on a Panzer IV chassis would be possible and lead to a compact (and whiffy) new vehicle?
Well, it would not work, because the Coelian turret needs a considerably bigger turret bearing diameter than anything the Panzer IV hull could realistically handle (even the Panther’s Schmalturm is actually a little too wide…), and so I folded the idea up again and put it onto the “vague ideas” pile.
…until I stumbled upon the leftover hull from a Hasegawa Panther Ausf. F in the donor kits pile, which had originally given both of its OOB turrets (a Schmalturm and a standard model) to other conversions. While mating the Coelian turret with its originally intended hull was not a sexy project, I eventually did so, because I could effectively use two leftovers for something sound and well-balanced.
Concerning the assembly phase, there’s not much to tell about the Hasegawa Panther Ausf. F. Fit is good, a simple kit, and it comes, as a benefit, with optional all-steel wheels which I used for my conversion, changing the overall look to a true late war model. Only the opening for the turret had to be widened in order to accept the new resin turret.
The latter only consists of two parts: the massive core section and a separate weapon mount. The latter was in so far modified that I added a simple metal peg which can be switched between two holes in the turret hull, for two gun positions.
Since the original gun barrels had to be replaced, anyway, I did a thorough (and fictional) modification: I used four 1:48 20 mm brass barrels for a Flak 38 Flakvierling (from RB Models) and mounted them in two staggered pairs onto the original cannon fairing. The resulting gun array looks impressive and even realistic, and, thanks to the scale-o-rama effect, the 1:48 parts have the perfect size for 30 mm cannon barrels in 1:72!
Painting and markings:
Something “German”, but nothing spectacular, so I ended up with another variant of the Hinterhalt scheme, found on a Jagdpanther from the Ardennenoffensive period. In this case, the prominent colors are Dunkelgelb and Olivgrün in broad stripes, separated by blurred, thin lines made of Rotbraun.
As a little twist I wanted to modify the scheme in so far that this vehicle was to show its conversion heritage in a workshop, so hull and turret received different basic tones as an initial step.
The hull and all wheels were painted with matt RAL 7028 (a modern equivalent to the WWII Dunkelgelb), while the turret received a red primer coat with Oxidrot (RAL 3009). On top of these, wide green bands (RAL 6003 from Modelmaster) and separating russet (Humbrol 113) stripes were painted with brushes. In order to brighten up the relatively dark turret, some yellow mottles were added on the Oxidrot areas (using Revell 16).
Once dry, the whole surface received a sand paper treatment, so that the RAL 7028 would shine through here and there, as if worn out. After a dark brown wash, details were emphasized with dry-brushing in light grey and beige. Decals were puzzled together from various German tank sheets, and the kit finally sealed with matt acrylic varnish.
The black vinyl tracks were also painted/weathered, with a wet-in-wet mix of black, iron and red brown (all acrylics). Once they were mounted into place, mud and dust around the running gear and the lower hull was simulated with a greyish-brown mix of artist mineral pigments.
A bit of recycling and less exotic than originally hoped for – but it’s still a whiffy tank model, and its proximity to the real but unrealized Coelian project makes this one even more subtle. Pile reduction, one by one…
