Some background:
The TIE/LN starfighter, or TIE/line starfighter, simply known as the TIE Fighter or T/F, was the standard Imperial starfighter seen in massive numbers throughout most of the Galactic Civil War and onward.
The TIE Fighter was manufactured by Sienar Fleet Systems and led to several upgraded TIE models such as TIE/sa bomber, TIE/IN interceptor, TIE/D Defender, TIE/D automated starfighter, and many more.
The original TIEs were designed to attack in large numbers, overwhelming the enemy craft. The Imperials used so many that they came to be considered symbols of the Empire and its might. They were also very cheap to produce, reflecting the Imperial philosophy of quantity over quality.
However, a disadvantage of the fighter was its lack of deflector shields. In combat, pilots had to rely on the TIE/LN's maneuverability to avoid damage. The cockpit did incorporate crash webbing, a repulsorlift antigravity field, and a high-g shock seat to help protect the pilot, however these did next to nothing to help protect against enemy blaster fire.
Due to the lack of life-support systems, each TIE pilot had a fully sealed flight suit superior to their Rebel counterparts. The absence of a hyperdrive also rendered the light fighter totally dependent on carrier ships when deployed in enemy systems. TIE/LNs also lacked landing gear, another mass-reducing measure. While the ships were structurally capable of "sitting" on their wings, they were not designed to land or disembark their pilots without special support. On Imperial ships, TIEs were launched from racks in the hangar bays.
The high success rate of more advanced Rebel starfighters against standard Imperial TIE Fighters resulted in a mounting cost of replacing destroyed fighters and their pilots. That, combined with the realization that the inclusion of a hyperdrive would allow the fleet to be more flexible, caused the Imperial Navy to rethink its doctrine of using swarms of cheap craft instead of fewer high-quality ones, leading to the introduction of the TIE Advanced x1 and its successor, the TIE Avenger. The following TIE/D Defender as well as the heavy TIE Escort Fighter (or TIE/E) were touted as the next "logical advance" of the TIE Series—representing a shift in starfighter design from previous, expendable TIE models towards fast, well armed and protected designs, capable of hyperspace travel and long-term crew teams which gained experience and capabilities over time.
The TIE/E Escort, was a high-performance TIE Series starfighter developed for the Imperial Navy by Sienar Fleet Systems and it was introduced into service shortly before the Battle of Endor. It was a much heavier counterpart to the agile and TIE/D fighter, and more of an attack ship or even a light bomber than a true dogfighter. Its role were independent long range operations, and in order to reduce the work load and boost morale a crew of two was introduced (a pilot and a dedicated weapon systems officer/WSO). The primary duty profile included attack and escort task, but also reconnoiter missions. The TIE/E shared the general layout with the contemporary TIE/D fighter, but the cockpit section as well as the central power unit were much bigger, and the ship was considerably heavier.
The crew enjoyed – compared with previous TIE fighter designs – a spacious and now fully pressurized cockpit, so that no pressurized suits had to be worn anymore. The crew members sat in tandem under a large, clear canopy. The pilot in front had a very good field of view, while the WSO sat behind him, in a higher, staggered position with only a limited field of view. Both work stations had separate entries, though, and places could not be switched in flight: the pilot mounted the cockpit through a hatch on port side, while the WSO entered the rear compartment through a roof hatch.
In a departure from the design of previous TIE models, instead of two parallel wings to either side of the pilot module, the TIE Escort had three quadanium steel solar array wings mounted symmetrically around an aft section, which contained an I-s4d solar ionization reactor to store and convert solar energy collected from the wing panels. The inclusion of a third wing provided additional solar power to increase the ship's range and the ship's energy management system was designed to allow weapons and shields to be charged with minimum loss of power to the propulsion system.
Although it was based on the standard twin ion engine design, the TIE/E’s propulsion system was upgraded to the entirely new, powerful P-sz9.8 triple ion engine. This allowed the TIE/E a maximum acceleration of 4,220 G or 21 MGLT/s and a top speed of 144 MGLT, or 1,680 km/h in an atmosphere — almost 40 percent faster than a former standard TIE Fighter. With tractor beam recharge power (see below) redirected to the engines, the top speed could be increased to 180 MGLT in a dash.
In addition to the main thrusters located in the aft section, the TIE Escort's triple wing design allowed for three arrays of maneuvering jets and it featured an advanced F-s5x flight avionics system to process the pilot's instructions. Production models received a class 2, ND9 hyperdrive motivator, modified from the version developed for the TIE Avenger. The TIE/E also carried a Sienar N-s6 Navcon navigation computer with a ten-jump memory.
Special equipment included a small tractor beam projector, originally developed for the TIE Avenger, which could be easily fitted to the voluminous TIE Escort. Models produced by Ysanne Isard's production facility regularly carried such tractor beams and the technology found other uses, such as towing other damaged starfighters until they could achieve the required velocity to enter hyperspace. The tractor beam had limited range and could only be used for a short time before stopping to recharge, but it added new tactics, too. For instance, the beam allowed the TIE/E crews to temporarily inhibit the mobility of enemy fighters, making it easier to target them with the ship's other weapon systems, or prevent enemies from clear shots.
The TIE Escort’s weapons systems were primarily designed to engage bigger ships and armored or shielded targets, like armed freighters frequently used by the Alliance. Thanks to its complex weapon and sensor suite, it could also engage multiple enemy fighters at once. The sensors also allowed an effective attack of ground targets, so that atmospheric bombing was a potential mission for the TIE/E, too.
.
The TIE Escort Fighter carried a formidable array of weaponry in two modular weapon bays that were mounted alongside the lower cabin. In standard configuration, the TIE/E had two L-s9.3 laser cannons and two NK-3 ion cannons. The laser and ion cannons could be set to fire separately or, if concentrated power was required, to fire-linked in either pairs or as a quartet.
The ship also featured two M-g-2 general-purpose warhead launchers, each of which could be equipped with a standard load of three proton torpedoes or four concussion missiles. Depending on the mission profile, the ship could be fitted with alternative warheads such as proton rockets, proton bombs, or magnetic pulse warheads.
Additionally, external stores could be carried under the fuselage, which included a conformal sensor pallet for reconnaissance missions or a cargo bay with a capacity for 500 kg (1.100 lb).
The ship's defenses were provided by a pair of forward and rear projecting Novaldex deflector shield generators—another advantage over former standard TIE models. The shields were designed to recharge more rapidly than in previous Imperial fighters and were nearly as powerful as those found on capital ships, so that the TIE/E could engage other ships head-on with a very high survivability. The fighters were not equipped with particle shields, though, relying on the reinforced titanium hull to absorb impacts from matter. Its hull and wings were among the strongest of any TIE series Starfighter yet.
The advanced starfighter attracted the attention of several other factions, and the Empire struggled to prevent the spread of the technology. The ship's high cost, together with political factors, kept it from achieving widespread use in the Empire, though, and units were assigned only to the most elite crews.
The TIE/E played a central role in the Empire's campaign against rogue Grand Admiral Demetrius Zaarin, and mixed Defender and Escort units participated in several other battles, including the Battle of Endor. The TIE Escort continued to see limited use by the Imperial Remnant up to at least 44 ABY, and was involved in numerous conflicts, including the Yuuzhan Vong War..
The kit and its assembly:
Another group build contribution, this time to the Science Fiction GB at whatifmodelers.com during summer 2017. Originally, this one started as an attempt to build a vintage MPC TIE Interceptor kit which I had bought and half-heartedly started to build probably 20 years ago. But I did not have the right mojo (probably, The Force was not strong enough…?), so the kit ended up in a dark corner and some parts were donated to other projects.
The sun collectors were still intact, though, and in the meantime I had the idea of reviving the kit’s remains, and convert it into (what I thought was) a fictional TIE Fighter variant with three solar panels. For this plan I got myself another TIE Interceptor kit, and stashed it away, too. Mojo was still missing, though.
Well, then came the SF GB and I took it as an occasion to finally tackle the build. But when I prepared for the build I found out that my intended design (over the years) more or less actually existed in the Star Wars universe: the TIE/D Defender! I could have built it with the parts and hand and some improvisation, but the design similarity bugged me. Well, instead of a poor copy of something that was more or less clearly defined, I rather decided to create something more individual, yet plausible, from the parts at hand.
The model was to stay a TIE design, though, in order to use as much donor material from the MPC kits as possible. Doing some legwork, I settled for a heavy fighter – bigger than the TIE Interceptor and the TIE/D fighter, a two-seater.
Working out the basic concept and layout took some time and evolved gradually. The creative spark for the TIE/E eventually came through a Revell “Obi Wan’s Jedi Starfighter” snap fit kit in my pile – actually a prize from a former GB participation at phoxim.de (Thanks a lot, Wolfgang!), and rather a toy than a true model kit.
The Jedi Fighter was in so far handy as it carries some TIE Fighter design traits, like the pilot capsule and the characteristic spider web windscreen. Anyway, it’s 1:32, much bigger than the TIE Interceptor’s roundabout 1:50 scale – but knowing that I’d never build the Jedi Starfighter OOB I used it as a donor bank, and from this starting point things started to evolve gradually.
Work started with the cockpit section, taken from the Jedi Starfighter kit. The two TIE Interceptor cockpit tubs were then mounted inside, staggered, and the gaps to the walls filled with putty. A pretty messy task, and once the shapes had been carved out some triangular tiles were added to the surfaces – a detail I found depicted in SW screenshots and some TIE Fighter models.
Another issue became the crew – even though I had two MPC TIE Interceptors and, theorectically, two pilot figures, only one of them could be found and the second crewman had to be improvised. I normally do not build 1:48 scale things, but I was lucky (and happy) to find an SF driver figure, left over from a small Dougram hoovercraft kit (from Takara, as a Revell “Robotech” reboxing). This driver is a tad bigger than the 1:50 TIE pilot, but I went with it because I did not want to invest money and time in alternatives. In order to justify the size difference I decided to paint the Dougram driver as a Chiss, based on the expanded SW universe (with blue skin and hair, and glowing red eyes). Not certain if this makes sense during the Battle of Endor timeframe, but it adds some color to the project – and the cockpit would not be visible in much detail since it would be finished fully closed.
Reason behind the closed canopy is basically the poor fit of the clear part. OOB, this is intended as an action toy – but also the canopy’s considerable size in 1:50 would prevent its original opening mechanism.
Additional braces on the rel. large window panels were created with self-adhesive tape and later painted over.
The rear fuselage section and the solar panel pylons were scratched. The reactor behind the cockpit section is actually a plastic adapter for water hoses, found in a local DIY market. It was slightly modified, attached to the cockpit “egg” and both parts blended with putty. The tail opening was closed with a hatch from the OOB TIE Interceptor – an incidental but perfect match in size and style.
The three pylons are also lucky finds: actually, these are SF wargaming/tabletop props and would normally be low walls or barriers, made from resin. For my build, they were more or less halved and trimmed. Tilted by 90°, they are attached to the hull with iron wire stabilizers, and later blended to the hull with putty, too.
Once the cockpit was done, things moved more swiftly. The surface of the hull was decorated with many small bits and pieces, including thin styrene sheet and profiles, steel and iron wire in various strengths, and there are even 1:72 tank tracks hidden somewhere, as well as protective caps from syringes (main guns and under the rear fuselage). It’s amazing how much stuff you can add to such a model – but IMHO it’s vital in order to create some structure and to emulate the (early) Star Wars look.
Painting and markings:
The less spectacular part of the project, even though still a lot of work because of the sheer size of the model’s surface. Since the whole thing is fictional, I tried to stay true to the Imperial designs from Episode IV-VI and gave the TIE/E a simple, all-light grey livery. All basic painting was done with rattle cans.
Work started with a basic coat of grey primer. On top of that, an initial coat of RAL 7036 Platingrau was added, esp. to the lower surfaces and recesses, for a rough shading effect. Then, the actual overall tone, RAL 7047, called “Telegrau 4”, one of Deutsche Telekom’s corporate tones, was added - mostly sprayed from abone and the sides onto the model. Fuselage and panels were painted separately, overall assembly was one of the final steps.
The solar panels were to stand out from the grey rest of the model, and I painted them with Revell Acrylic “Iron Metallic” (91) first, and later applied a rather rich wash with black ink , making sure the color settled well into the many small cells. The effect is pretty good, and the contrast was slightly enhanced through a dry-brushing treatment.
Only a few legible stencils were added all around the hull (most from the scrap box or from mecha sheets), the Galactic Empire Seal were inkjet-printed at home, as well as some tactical markings on the flanks, puzzled together from single digits in "Aurebash", one of the Imperial SW languages/fonts.
For some variety and color highlights, dozens of small, round and colorful markings were die-punched from silver, yellow, orange, red and blue decal sheet and were placed all over the hull - together with the large panels they blur into the the overall appearance, though. The hatches received thin red linings, also made from generic decals strips.
The cockpit interior was a bit challenging, though. Good TIE Fighter cockpit interior pictures are hard to find, but they suggest a dark grey tone. More confusingly, the MPC instructions call for a “Dark Green” cockpit? Well, I did not like the all-grey option, since the spaceship is already monochrome grey on the outside.
As a compromise I eventually used Tamiya XF-65 "Field Grey". The interior recieved a black ink in and dry-brushing treatment, and some instruments ansd screens were created with black decal material and glossy black paint; some neon paint was used for sci-fi-esque conmtraol lamps everywhere - I did not pay too much intention on the interior, since the cockpit would stay closed, and the thick clear material blurs everything inside.
Following this rationale, the crew was also painted in arather minimal fashion - both wear a dark grey uniform, only the Chiss pilot stands aout with his light blue skin and the flourescent red eyes.
After an overall black ink wash the model received a dry brusing treatment with FS 36492 and FS 36495, for a weathered and battle-worn look. After all, the "Vehement" would not survive the Ballte of Endor, but who knows what became of TIE/E "801"'s mixed crew...?
Finally, the kit was sealed with matt acrylic varnish, and some final cosmetic corrections made.
The display is a DIY creation, too, made from a 6x6" piece of wood, it's edges covered with edgebonder, a steel wire as holder, and finally the display was paited with semi-matt black acrylic paint from the rattle can.
A complex build, and the TIE/E more or less evolved along the way, with only the overall layout in mind. Work took a month, but I think it was worth the effort. This fantasy creation looks pretty plausible and blends well into the vast canonical TIE Fighter family - and I am happy that I finally could finish this mummy project, including the surplus Jedi Starfighter kit which now also find a very good use!
An epic one, and far outside my standard comfort zone. But a wothwhile build!

Some background
The Focke Wulf Ta 338 originated as a response of request by the RLM in mid 1943 for an aircraft capable of vertical takeoff and landing (VTOL), optimized for the interceptor and point defense role and without a hazardous liquid rocket engine as means of propulsion. In the course of the year, several German manufacturers responded with a multitude of highly innovative if not unusual design, including Heinkel with the ducted fan project "Lerche", Rheinmetall-Borsig with a jet-powered tailsitter, and Focke Wulf. This company’s engineering teams submitted two designs: the revolutionary "Triebflügel" concept and the more conservative, yet still futuristic "P.03.10338" tail sitter proposal, conceived by Focke Wulf’s leading engineer Kurt Tank and Walter Kappus from BMW, responsible for the engine development.
The P.03.10338 was based on the proven Fw 190 fighter, but the similarities were only superficial. Only the wings and a part of the fuselage structure around the cockpit would be used, but Tank assumed that using existing parts and tools would appreciably reduce development and production time.
A great part of the fuselage structure had to be re-designed to accommodate a powerful BMW 803 engine and its integral gearbox for an eight-bladed contraprop.
The BMW 803 was BMW's attempt to build a high-output aircraft engine, primarily for heavy bombers, by basically "coupling" two BMW 801 engines back-to-back into a single and very compact power unit. The result was a 28-cylinder, four-row radial engine, each comprising a multiple-bank in-line engine with two cylinders in each bank, which, due to cooling concerns, were liquid cooled.
This arrangement was from the start intended to drive independent contra-rotating propellers, in order to avoid stiffness problems with the whole engine driving just a single crankshaft and also to simply convert the raw power of this unit into propulsion. The front half of the engine drove the front propeller directly, while the rear engine drove a number of smaller shafts that passed between the cylinders of the front engine before being geared back together to drive the rear prop. This complex layout resulted in a rather large and heavy gearbox on the front of the engine, and the front engine needing an extended shaft to "clear" that gearbox. The four-row 803 engine weighed 2,950 kg (6,490 lb) dry and 4,130 kg (9,086 lb) fully loaded, and initial versions delivered 3,900 PS (3,847 hp; 2,868 kW).
While the engine was heavy and there were alternatives with a better weight/output ratio (e. g. the Jumo 222), the BMW 803 was favored for this project because it was the most powerful engine available, and it was relatively compact so that it could be fitted into a fighter's airframe. On the P.03.10338 it drove an all-metal, eight-blade contraprop with a diameter of 4,25 m (13 ft 11 in).
In order to accept this massive engine, the P.03.10338’s structure had to be stiffened and the load-bearing structures re-arranged. The aircraft kept the Fw 190's wing structure and surface, but the attachment points at the fuselage had to be moved for the new engine mount, so that they ended up in mid position. The original space for the Fw 190's landing gear was used for a pair of radiator baths in the wings' inner leading edge, the port radiator catering to the front engine half while the radiator on starboard was connected with the rear half. An additional annular oil and sodium cooler for the gearbox and the valve train, respectively, was mounted in the fuselage nose.
The tail section was completely re-designed. Instead of the Fw 190's standard tail with fin and stabilizers the P.03.10338’s tail surfaces were a reflected cruciform v-tail (forming an x) that extended above and below the fuselage. On the four fin tips, aerodynamic bodies carried landing pads while the fuselage end contained an extendable landing damper. The pilot sat in a standard Fw 190 cockpit, and the aircraft was supposed to start and land vertically from a mobile launch pad. In the case of an emergency landing, the lower stabilizers could be jettisoned. Nor internal armament was carried, instead any weaponry was to be mounted under the outer wings or the fuselage, in the form of various “Rüstsätze” packages.
Among the many exotic proposals to the VTOL fighter request, Kurt Tank's design appeared as one of the most simple options, and the type received the official RLM designation Ta 338. In a rush of urgency (and maybe blinded by clever Wunderwaffen marketing from Focke Wulf’s side), a series of pre-production aircraft was ordered instead of a dedicated prototype, which was to equip an Erprobungskommando (test unit, abbreviated “EK”) that would evaluate the type and develop tactics and procedures for the new fighter.
Fueled by a growing number of bomber raids over Germany, the “EK338” was formed as a part of JG300 in August 1944 in Schönwalde near Berlin, but it took until November 1944 that the first Ta 338 A-0 machines were delivered and made operational. These initial eight machines immediately revealed several flaws and operational problems, even though the VTOL concept basically worked and the aircraft flew well – once it was in the air and cruising at speeds exceeding 300 km/h (186 mph).
Beyond the many difficulties concerning the aircraft’s handling (esp. the landing was hazardous), the lack of a landing gear hampered ground mobility and servicing. Output of the BMW 803 was sufficient, even though the aircraft had clear limits concerning the take-off weight, so that ordnance was limited to only 500 kg (1.100 lb). Furthermore, the noise and the dust kicked up by starting or landing aircraft was immense, and servicing the engine or the weapons was more complicated than expected through the high position of many vital and frequently tended parts.
After three Ta 338 A-0 were lost in accidents until December 1944, a modified version was ordered for a second group of the EK 338. This led to the Ta 338 A-1, which now had shorter but more sharply swept tail fins that carried single wheels and an improved suspension under enlarged aerodynamic bodies.
This machine was now driven by an improved BMW 803 A-2 that delivered more power and was, with an MW-50 injection system, able to produce a temporary emergency output of 4.500 hp (3.308 kW).
Vertical start was further assisted by optional RATO units, mounted in racks at the rear fuselage flanks: either four Schmidding SG 34 solid fuel booster rockets, 4.9 kN (1,100 lbf) thrust each, or two larger 9.8 kN (2,203 lbf) solid fuel booster rockets, could be used. These improvements now allowed a wider range of weapons and equipment to be mounted, including underwing pods with unguided rockets against bomber pulks and also a conformal pod with two cameras for tactical reconnaissance.
The hazardous handling and the complicated maintenance remained the Ta 338’s Achilles heel, and the tactical benefit of VTOL operations could not outbalance these flaws. Furthermore, the Ta 338’s range remained very limited, as well as the potential firepower. Four 20mm or two 30mm cannons were deemed unsatisfactory for an interceptor of this class and power. And while bundles of unguided missiles proved to be very effective against large groups of bombers, it was more efficient to bring these weapons with simple and cheap vehicles like the Bachem Ba 349 Natter VTOL rocket fighter into target range, since these were effectively “one-shot” weapons. Once the Ta 338 fired its weapons it had to retreat unarmed.
In mid 1945, in the advent of defeat, further tests of the Ta 338 were stopped. I./EK338 was disbanded in March 1945 and all machines retreated from the Eastern front, while II./EK338 kept defending the Ruhrgebiet industrial complex until the Allied invasion in April 1945. Being circled by Allied forces, it was not possible to evacuate or destroy all remaining Ta 338s, so that at least two more or less intact airframes were captured by the U.S. Army and later brought to the United States for further studies.

The kit and its assembly:
This purely fictional kitbashing is a hardware tribute to a highly inspiring line drawing of a Fw 190 VTOL tailsitter – actually an idea for an operational RC model! I found the idea, that reminded a lot of the Lockheed XFV-1 ‘Salmon’ prototype, just with Fw 190 components and some adaptations, very sexy, and so I decided on short notice to follow the urge and build a 1:72 version of the so far unnamed concept.
What looks simple (“Heh, it’s just a Fw 190 with a different tail, isn’t it?”) turned out to become a major kitbashing. The basis was a simple Hobby Boss Fw 190 D-9, chose because of the longer tail section, and the engine would be changed, anyway. Lots of work followed, though.
The wings were sliced off and moved upwards on the flanks. The original tail was cut off, and the cruciform fins are two pairs of MiG-21F stabilizers (from an Academy and Hasegawa kit), outfitted with reversed Mk. 84 bombs as aerodynamic fairings that carry four small wheels (from an 1:144 T-22M bomber) on scratched struts (made from wire).
The cockpit was taken OOB, only a pilot figure was cramped into the seat in order to conceal the poor interior detail. The engine is a bash from a Ju 188’s BMW 801 cowling and the original Fw 190 D-9’s annular radiator as well as a part of its Jumo 213 cowling. BMW 801 exhaust stubs were inserted, too, and the propeller comes from a 1:100 VEB Plasticart Tu-20/95 bomber.
Since the BMW 803 had liquid cooling, radiators had to go somewhere. The annular radiator would certainly not have been enough, so I used the space in the wings that became available through the deleted Fw 190 landing gear (the wells were closed) for additional radiators in the wings’ leading edges. Again, these were scratched with styrene profiles, putty and some very fine styrene mesh.
As ordnance I settled for a pair of gun pods – in this case these are slipper tanks from a Hobby Boss MiG-15, blended into the wings and outfitted with hollow steel needles as barrels.
Painting and markings:
Several design options were possible: all NMF with some colorful markings or an overall RLM76 finish with added camouflage. But I definitively went for a semi-finished look, inspired by late WWII Fw 190 fighters.
For instance, the wings’ undersides were partly left in bare metal, but the rudders painted in RLM76 while the leading edges became RLM75. This color was also taken on the wings’ upper sides, with RLM82 thinly painted over. The fuselage is standard RLM76, with RLM82 and 83 on the upper side and speckles on the flanks. The engine cowling became NMF, but with a flashy ‘Hartmann Tulpe’ decoration.
Further highlights are the red fuselage band (from JG300 in early 1945) and the propeller spinner, which received a red tip and segments in black and white on both moving propeller parts. Large red “X”s were used as individual aircraft code – an unusual Luftwaffe practice but taken over from some Me 262s.
After a light black ink wash some panel shading and light weathering (e.g. exhaust soot, leaked oil, leading edges) was done, and the kit sealed under matt acrylic varnish.
Building this “thing” on the basis of a line drawing was real fun, even though challenging and more work than expected. I tried to stay close to the drawing, the biggest difference is the tail – the MiG-21 stabilizers were the best option (and what I had at hand as donation parts), maybe four fins from a Hawker Harrier or an LTV A-7 had been “better”, but now the aircraft looks even faster. ;)
Besides, the Ta 338 is so utterly Luft ’46 – I am curious how many people might take this for real or as a Hydra prop from a contemporary Captain America movie…

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 English Electric Skyspark was a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2. The Skyspark was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Skyspark.
The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 program. W.E.W. "Teddy" Petter, formerly chief designer at Westland Aircraft, was a keen early proponent of Britain's need to develop a supersonic fighter aircraft. In 1947, Petter approached the Ministry of Supply (MoS) with his proposal, and in response Specification ER.103 was issued for a single research aircraft, which was to be capable of flight at Mach 1.5 (1,593 km/h) and 50,000 ft (15,000 m).
Petter initiated a design proposal with F W "Freddie" Page leading the design and Ray Creasey responsible for the aerodynamics. As it was designed for Mach 1.5, it had a 40° swept wing to keep the leading edge clear of the Mach cone. To mount enough power into the airframe, two engines were installed, in an unusual, stacked layout and with a high tailplane This proposal was submitted in November 1948, and in January 1949 the project was designated P.1 by English Electric. On 29 March 1949 MoS granted approval to start the detailed design, develop wind tunnel models and build a full-size mock-up.
The design that had developed during 1948 evolved further during 1949 to further improve performance. To achieve Mach 2 the wing sweep was increased to 60° with the ailerons moved to the wingtips. In late 1949, low-speed wind tunnel tests showed that a vortex was generated by the wing which caused a large downwash on the initial high tailplane; this issue was solved by lowering the tail below the wing. Following the resignation of Petter, Page took over as design team leader for the P.1. In 1949, the Ministry of Supply had issued Specification F23/49, which expanded upon the scope of ER103 to include fighter-level manoeuvring. On 1 April 1950, English Electric received a contract for two flying airframes, as well as one static airframe, designated P.1.
The Royal Aircraft Establishment disagreed with Petter's choice of sweep angle (60 degrees) and the stacked engine layout, as well as the low tailplane position, was considered to be dangerous, too. To assess the effects of wing sweep and tailplane position on the stability and control of Petter's design Short Brothers were issued a contract, by the Ministry of Supply, to produce the Short SB.5 in mid-1950. This was a low-speed research aircraft that could test sweep angles from 50 to 69 degrees and tailplane positions high or low. Testing with the wings and tail set to the P.1 configuration started in January 1954 and confirmed this combination as the correct one. The proposed 60-degree wing sweep was retained, but the stacked engines had to give way to a more conventional configuration with two engines placed side-by-side in the tail, but still breathing through a mutual nose air intake.
From 1953 onward, the first three prototype aircraft were hand-built at Samlesbury. These aircraft had been assigned the aircraft serials WG760, WG763, and WG765 (the structural test airframe). The prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, as the selected Rolls-Royce Avon engines had fallen behind schedule due to their own development problems. Since there was not much space in the fuselage for fuel, the thin wings became the primary fuel tanks and since they also provided space for the stowed main undercarriage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance. The narrow tires housed in the thin wings rapidly wore out if there was any crosswind component during take-off or landing. Outwardly, the prototypes looked very much like the production series, but they were distinguished by the rounded-triangular air intake with no center-body at the nose, short fin, and lack of operational equipment.
On 9 June 1952, it was decided that there would be a second phase of prototypes built to develop the aircraft toward achieving Mach 2.0 (2,450 km/h); these were designated P.1B while the initial three prototypes were retroactively reclassified as P.1A. P.1B was a significant improvement on P.1A. While it was similar in aerodynamics, structure and control systems, it incorporated extensive alterations to the forward fuselage, reheated Rolls Royce Avon R24R engines, a conical center body inlet cone, variable nozzle reheat and provision for weapons systems integrated with the ADC and AI.23 radar. Three P.1B prototypes were built, assigned serials XA847, XA853 and XA856.
In May 1954, WG760 and its support equipment were moved to RAF Boscombe Down for pre-flight ground taxi trials; on the morning of 4 August 1954, WG760 flew for the first time from Boscombe Down. One week later, WG760 officially achieved supersonic flight for the first time, having exceeded the speed of sound during its third flight. While WG760 had proven the P.1 design to be viable, it was plagued by directional stability problems and a dismal performance: Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of just 48,000 ft (14,630 m), far below the requirements.
To solve the problem and save the P.1, Petter embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed a new, narrower canopy, a revised air intake, a pair of stabilizing fins under the rear fuselage, and a shallow ventral fairing at the wings’ trailing edge that not only reduced the drag coefficient along the wing/fuselage intersection, it also provided space for additional fuel.
On 4 April 1957 the modified P.1B (XA847) made the first flight, immediately exceeding Mach 1. During the early flight trials of the P.1B, speeds in excess of 1,000 mph were achieved daily.
In late October 1958, the plane was officially presented. The event was celebrated in traditional style in a hangar at Royal Aircraft Establishment (RAE) Farnborough, with the prototype XA847 having the name ‘Skyspark’ freshly painted on the nose in front of the RAF Roundel, which almost covered it. A bottle of champagne was put beside the nose on a special rig which allowed the bottle to safely be smashed against the side of the aircraft.
On 25 November 1958 the P.1B XA847 reached Mach 2 for the first time. This made it the second Western European aircraft to reach Mach 2, the first one being the French Dassault Mirage III just over a month earlier on 24 October 1958
The first operational Skyspark, designated Skyspark F.1, was designed as a pure interceptor to defend the V Force airfields in conjunction with the "last ditch" Bristol Bloodhound missiles located either at the bomber airfield, e.g. at RAF Marham, or at dedicated missile sites near to the airfield, e.g. at RAF Woodhall Spa near the Vulcan station RAF Coningsby. The bomber airfields, along with the dispersal airfields, would be the highest priority targets in the UK for enemy nuclear weapons. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range – originally a radius of operation of only 150 miles (240 km) from the V bomber airfields was specified – and endurance. Armament consisted of a pair of 30 mm ADEN cannon in front of the cockpit, and two pylons for IR-guided de Havilland Firestreak air-to-air missiles were added to the lower fuselage flanks. These hardpoints could, alternatively, carry pods with unguided 55 mm air-to-air rockets. The Ferranti AI.23 onboard radar provided missile guidance and ranging, as well as search and track functions.
The next two Skyspark variants, the Skyspark F.1A and F.2, incorporated relatively minor design changes, but for the next variant, the Skyspark F.3, they were more extensive: The F.3 had higher thrust Rolls-Royce Avon 301R engines, a larger squared-off fin that improved directional stability at high speed further and a strengthened inlet cone allowing a service clearance to Mach 2.0 (2,450 km/h; the F.1, F.1A and F.2 were all limited to Mach 1.7 (2,083 km/h). An upgraded A.I.23B radar and new, radar-guided Red Top missiles offered a forward hemisphere attack capability, even though additional electronics meant that the ADEN guns had to be deleted – but they were not popular in their position in front of the windscreen, because the muzzle flash blinded the pilot upon firing. The new engines and fin made the F.3 the highest performance Skyspark yet, but this came at a steep price: higher fuel consumption, resulting in even shorter range. From this basis, a conversion trainer with a side-by-side cockpit, the T.4, was created.
The next interceptor variant was already in development, but there was a need for an interim solution to partially address the F.3's shortcomings, the F.3A. The F.3A introduced two major improvements: a larger, non-jettisonable, 610-imperial-gallon (2,800 L) ventral fuel tank, resulting in a much deeper and longer belly fairing, and a new, kinked, conically cambered wing leading edge. The conically cambered wing improved manoeuvrability, especially at higher altitudes, and it offered space for a slightly larger leading edge fuel tank, raising the total usable internal fuel by 716 imperial gallons (3,260 L). The enlarged ventral tank not only nearly doubled available fuel, it also provided space at its front end for a re-instated pair of 30 mm ADEN cannon with 120 RPG. Alternatively, a retractable pack with unguided 55 mm air-to-air rockets could be installed, or a set of cameras for reconnaissance missions. The F.3A also introduced an improved A.I.23B radar and the new IR-guided Red Top missile, which was much faster and had greater range and manoeuvrability than the Firestreak. Its improved infrared seeker enabled a wider range of engagement angles and offered a forward hemisphere attack capability that would allow the Skyspark to attack even faster bombers (like the new, supersonic Tupolev T-22 Blinder) through a collision-course approach.
Wings and the new belly tank were also immediately incorporated in a second trainer variant, the T.5.
The ultimate variant, the Skyspark F.6, was nearly identical to the F.3A, with the exception that it could carry two additional 260-imperial-gallon (1,200 L) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency and gave the F.6 a substantially improved deployment capability, even though their supersonic drag was so high that the extra fuel would only marginally raise the aircraft’s range when flying beyond the sound barrier for extended periods.
Finally, there was the Skyspark F.2A; it was an early production F.2 upgraded with the new cambered wing, the squared fin, and the 610 imperial gallons (2,800 L) ventral tank. However, the F.2A retained the old AI.23 radar, the IR-guided Firestreak missile and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Skysparks, it had the longest tactical range of all variants, and was used for low-altitude interception over West Germany.
The first Skysparks to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Skyspark for entry into service. The production Skyspark F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Skyspark F.1 entered frontline squadron service with 74 Squadron at Coltishall from 11 July 1960. This made the Skyspark the second Western European-built combat aircraft with true supersonic capability to enter service and the second fully supersonic aircraft to be deployed in Western Europe (the first one in both categories being the Swedish Saab 35 Draken on 8 March 1960 four months earlier).
The aircraft's radar and missiles proved to be effective, and pilots reported that the Skyspark was easy to fly. However, in the first few months of operation the aircraft's serviceability was extremely poor. This was due to the complexity of the aircraft systems and shortages of spares and ground support equipment. Even when the Skyspark was not grounded by technical faults, the RAF initially struggled to get more than 20 flying hours per aircraft per month compared with the 40 flying hours that English Electric believed could be achieved with proper support. In spite of these concerns, within six months of the Skyspark entering service, 74 Squadron was able to achieve 100 flying hours per aircraft.
Deliveries of the slightly improved Skyspark F.1A, with revised avionics and provision for an air-to-air refueling probe, allowed two more squadrons, 56 and 111 Squadron, both based at RAF Wattisham, to convert to the Skyspark in 1960–1961. The Skyspark F.1 was only ordered in limited numbers and served only for a short time; nonetheless, it was viewed as a significant step forward in Britain's air defence capabilities. Following their replacement from frontline duties by the introduction of successively improved Skyspark variants, the remaining F.1 aircraft were employed by the Skyspark Conversion Squadron.
The improved F.2 entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the of the two-seat T.4 and T.5 trainers (based on the F.3 and F.3A/F.6 fighters), which entered service with the Skyspark Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two-seater, small numbers were also allocated to the front-line fighter squadrons. More F.2s were produced than there were available squadron slots, so later production aircraft were stored for years before being used operationally; some of these Skyspark F.2s were converted to F.2As.
The F.3, with more powerful engines and the new Red Top missile was expected to be the definitive Skyspark, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. However, the F.3 also had only a short operational life and was withdrawn from service early due to defence cutbacks and the introduction of the even more capable and longer-range F.6, some of which were converted F.3s.
The introduction of the F.3 and F.6 allowed the RAF to progressively reequip squadrons operating aircraft such as the subsonic Gloster Javelin and retire these types during the mid-1960s. During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Skyspark's range and firepower shortcomings became increasingly apparent. The transfer of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force, alongside those withdrawn from Germany as they were replaced by SEPECAT Jaguars in the ground attack role.
The Skyspark's direct replacement was the Tornado F.3, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Skyspark, including far larger weapons load and considerably more advanced avionics. Skysparks were slowly phased out of service between 1974 and 1988, even though they lasted longer than expected because the definitive Tornado F.3 went through serious teething troubles and its service introduction was delayed several times. In their final years, the Skysparks’ airframes required considerable maintenance to keep them airworthy due to the sheer number of accumulated flight hours.

The kit and its assembly:
This build was a submission to the “Hunter, Lightning, Canberra” group build at whatifmodellers.com, and one of my personal ultimate challenges – a project that you think about very often, but the you put the thought back into its box when you realize that turning this idea into hardware will be a VERY tedious, complex and work-intensive task. But the thematic group build was the perfect occasion to eventually tackle the idea of a model of a “side-by-side engine BAC Lightning”, a.k.a. “Flatning”, as a rather conservative alternative to the real aircraft’s unique and unusual design with stacked engines in the fuselage, which brought a multitude of other design consequences that led to a really unique aircraft.
And it sound so simple: take a Lightning, just change the tail section. But it’s not that simple, because the whole fuselage shape would be different, resulting in less depth, the wings have to be attached somewhere and somehow, the landing gear might have to be adjusted/shortened, and how the fuselage diameter shape changes along the hull, so that you get a more or less smooth shape, was also totally uncertain!
Initially I considered a MiG Ye-152 as a body donor, but that was rejected due to the sheer price of the only available kit (ModelSvit). A Chinese Shenyang J-8I would also have been ideal – but there’s not 1:72 kit of this aircraft around, just of its successor with side intakes, a 1:72 J-8II from trumpeter.
I eventually decided to keep costs low, and I settled for the shaggy PM Model Su-15 (marketed as Su-21) “Flagon” as main body donor: it’s cheap, the engines have a good size for Avons and the pen nib fairing has a certain retro touch that goes well with the Lightning’s Fifties design.
The rest of this "Flatning" came from a Hasegawa 1:72 BAC Lightning F.6 (Revell re-boxing).
Massive modifications were necessary and lots of PSR. In an initial step the Flagon lost its lower wing halves, which are an integral part of the lower fuselage half. The cockpit section was cut away where the intake ducts begin. The Lightning had its belly tank removed (set aside for a potential later re-installation), and dry-fitting and crude measures suggested that only the cockpit section from the Lightning, its spine and the separate fin would make it onto the new fuselage.
Integrating the parts was tough, though! The problem that caused the biggest headaches: how to create a "smooth" fuselage from the Lightning's rounded front end with a single nose intake that originally develops into a narrow, vertical hull, combined with the boxy and rather wide Flagon fuselage with large Phantom-esque intakes? My solution: taking out deep wedges from all (rather massive) hull parts along the intake ducts, bend the leftover side walls inwards and glue them into place, so that the width becomes equal with the Lightning's cockpit section. VERY crude and massive body work!
However, the Lightning's cockpit section for the following hull with stacked engines is much deeper than the Flagon's side-by-side layout. My initial idea was to place the cockpit section higher, but I would have had to transplant a part of the Lightning's upper fuselage (with the spine on top, too!) onto the "flat" Flagon’s back. But this would have looked VERY weird, and I'd have had to bridge the round ventral shape of the Lightning into the boxy Flagon underside, too. This was no viable option, so that the cockpit section had to be further modified; I cut away the whole ventral cockpit section, at the height of the lower intake lip. Similar to my former Austrian Hasegawa Lightning, I also cut away the vertical bulkhead directly behind the intake opening - even though I did not improve the cockpit with a better tub with side consoles. At the back end, the Flagon's jet exhausts were opened and received afterburner dummies inside as a cosmetic upgrade.
Massive PSR work followed all around the hull. The now-open area under the cockpit was filled with lead beads to keep the front wheel down, and I implanted a landing gear well (IIRC, it's from an Xtrakit Swift). With the fuselage literally taking shape, the wings were glued together and the locator holes for the overwing tanks filled, because they would not be mounted.
To mount the wings to the new hull, crude measurements suggested that wedges had to be cut away from the Lightning's wing roots to match the weird fuselage shape. They were then glued to the shoulders, right behind the cockpit due to the reduced fuselage depth. At this stage, the Lightning’s stabilizer attachment points were transplanted, so that they end up in a similar low position on the rounded Su-15 tail. Again, lots of PSR…
At this stage I contemplated the next essential step: belly tank or not? The “Flatning” would have worked without it, but its profile would look rather un-Lightning-ish and rather “flat”. On the other side, a conformal tank would probably look quite strange on the new wide and flat ventral fuselage...? Only experiments could yield an answer, so I glued together the leftover belly bulge parts from the Hasegawa kit and played around with it. I considered a new, wider belly tank, but I guess that this would have looked too ugly. I eventually settled upon the narrow F.6 tank and also used the section behind it with the arrestor hook. I just reduced its depth by ~2 mm, with a slight slope towards the rear because I felt (righteously) that the higher wing position would lower the model’s stance. More massive PSR followed….
Due to the expected poor ground clearance, the Lightning’s stabilizing ventral fins were mounted directly under the fuselage edges rather than on the belly tank. Missile pylons for Red Tops were mounted to the lower front fuselage, similar to the real arrangement, and cable fairings, scratched from styrene profiles, were added to the lower flanks, stretching the hull optically and giving more structure to the hull.
To my surprise, I did not have to shorten the landing gear’s main legs! The wings ended up a little higher on the fuselage than on the original Lightning, and the front wheel sits a bit further back and deeper inside of its donor well, too, so that the fuselage comes probably 2 mm closer to the ground than an OOB Lightning model. Just like on the real aircraft, ground clearance is marginal, but when the main wheels were finally in place, the model turned out to have a low but proper stance, a little F8U-ish.
Painting and markings:
I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.
A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.
After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.
Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.
A major effort, and I have seriously depleted my putty stocks for this build! However, the result looks less spectacular than it actually is: changing a Lightning from its literally original stacked engine layout into a more conservative side-by-side arrangement turned out to be possible, even though the outcome is not really pretty. But it works and is feasible!
I did a little more work on my model tonight. I didn't do a lot as I wanted to spend some time on Flickr this evening too. I did a second coat of paint on the window ledges on the side wall parts. I'll probably start assembly of the building tomorrow. :D

Some background:
The English Electric Skyspark was a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2. The Skyspark was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Skyspark.
The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 program. W.E.W. "Teddy" Petter, formerly chief designer at Westland Aircraft, was a keen early proponent of Britain's need to develop a supersonic fighter aircraft. In 1947, Petter approached the Ministry of Supply (MoS) with his proposal, and in response Specification ER.103 was issued for a single research aircraft, which was to be capable of flight at Mach 1.5 (1,593 km/h) and 50,000 ft (15,000 m).
Petter initiated a design proposal with F W "Freddie" Page leading the design and Ray Creasey responsible for the aerodynamics. As it was designed for Mach 1.5, it had a 40° swept wing to keep the leading edge clear of the Mach cone. To mount enough power into the airframe, two engines were installed, in an unusual, stacked layout and with a high tailplane This proposal was submitted in November 1948, and in January 1949 the project was designated P.1 by English Electric. On 29 March 1949 MoS granted approval to start the detailed design, develop wind tunnel models and build a full-size mock-up.
The design that had developed during 1948 evolved further during 1949 to further improve performance. To achieve Mach 2 the wing sweep was increased to 60° with the ailerons moved to the wingtips. In late 1949, low-speed wind tunnel tests showed that a vortex was generated by the wing which caused a large downwash on the initial high tailplane; this issue was solved by lowering the tail below the wing. Following the resignation of Petter, Page took over as design team leader for the P.1. In 1949, the Ministry of Supply had issued Specification F23/49, which expanded upon the scope of ER103 to include fighter-level manoeuvring. On 1 April 1950, English Electric received a contract for two flying airframes, as well as one static airframe, designated P.1.
The Royal Aircraft Establishment disagreed with Petter's choice of sweep angle (60 degrees) and the stacked engine layout, as well as the low tailplane position, was considered to be dangerous, too. To assess the effects of wing sweep and tailplane position on the stability and control of Petter's design Short Brothers were issued a contract, by the Ministry of Supply, to produce the Short SB.5 in mid-1950. This was a low-speed research aircraft that could test sweep angles from 50 to 69 degrees and tailplane positions high or low. Testing with the wings and tail set to the P.1 configuration started in January 1954 and confirmed this combination as the correct one. The proposed 60-degree wing sweep was retained, but the stacked engines had to give way to a more conventional configuration with two engines placed side-by-side in the tail, but still breathing through a mutual nose air intake.
From 1953 onward, the first three prototype aircraft were hand-built at Samlesbury. These aircraft had been assigned the aircraft serials WG760, WG763, and WG765 (the structural test airframe). The prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, as the selected Rolls-Royce Avon engines had fallen behind schedule due to their own development problems. Since there was not much space in the fuselage for fuel, the thin wings became the primary fuel tanks and since they also provided space for the stowed main undercarriage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance. The narrow tires housed in the thin wings rapidly wore out if there was any crosswind component during take-off or landing. Outwardly, the prototypes looked very much like the production series, but they were distinguished by the rounded-triangular air intake with no center-body at the nose, short fin, and lack of operational equipment.
On 9 June 1952, it was decided that there would be a second phase of prototypes built to develop the aircraft toward achieving Mach 2.0 (2,450 km/h); these were designated P.1B while the initial three prototypes were retroactively reclassified as P.1A. P.1B was a significant improvement on P.1A. While it was similar in aerodynamics, structure and control systems, it incorporated extensive alterations to the forward fuselage, reheated Rolls Royce Avon R24R engines, a conical center body inlet cone, variable nozzle reheat and provision for weapons systems integrated with the ADC and AI.23 radar. Three P.1B prototypes were built, assigned serials XA847, XA853 and XA856.
In May 1954, WG760 and its support equipment were moved to RAF Boscombe Down for pre-flight ground taxi trials; on the morning of 4 August 1954, WG760 flew for the first time from Boscombe Down. One week later, WG760 officially achieved supersonic flight for the first time, having exceeded the speed of sound during its third flight. While WG760 had proven the P.1 design to be viable, it was plagued by directional stability problems and a dismal performance: Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of just 48,000 ft (14,630 m), far below the requirements.
To solve the problem and save the P.1, Petter embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed a new, narrower canopy, a revised air intake, a pair of stabilizing fins under the rear fuselage, and a shallow ventral fairing at the wings’ trailing edge that not only reduced the drag coefficient along the wing/fuselage intersection, it also provided space for additional fuel.
On 4 April 1957 the modified P.1B (XA847) made the first flight, immediately exceeding Mach 1. During the early flight trials of the P.1B, speeds in excess of 1,000 mph were achieved daily.
In late October 1958, the plane was officially presented. The event was celebrated in traditional style in a hangar at Royal Aircraft Establishment (RAE) Farnborough, with the prototype XA847 having the name ‘Skyspark’ freshly painted on the nose in front of the RAF Roundel, which almost covered it. A bottle of champagne was put beside the nose on a special rig which allowed the bottle to safely be smashed against the side of the aircraft.
On 25 November 1958 the P.1B XA847 reached Mach 2 for the first time. This made it the second Western European aircraft to reach Mach 2, the first one being the French Dassault Mirage III just over a month earlier on 24 October 1958
The first operational Skyspark, designated Skyspark F.1, was designed as a pure interceptor to defend the V Force airfields in conjunction with the "last ditch" Bristol Bloodhound missiles located either at the bomber airfield, e.g. at RAF Marham, or at dedicated missile sites near to the airfield, e.g. at RAF Woodhall Spa near the Vulcan station RAF Coningsby. The bomber airfields, along with the dispersal airfields, would be the highest priority targets in the UK for enemy nuclear weapons. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range – originally a radius of operation of only 150 miles (240 km) from the V bomber airfields was specified – and endurance. Armament consisted of a pair of 30 mm ADEN cannon in front of the cockpit, and two pylons for IR-guided de Havilland Firestreak air-to-air missiles were added to the lower fuselage flanks. These hardpoints could, alternatively, carry pods with unguided 55 mm air-to-air rockets. The Ferranti AI.23 onboard radar provided missile guidance and ranging, as well as search and track functions.
The next two Skyspark variants, the Skyspark F.1A and F.2, incorporated relatively minor design changes, but for the next variant, the Skyspark F.3, they were more extensive: The F.3 had higher thrust Rolls-Royce Avon 301R engines, a larger squared-off fin that improved directional stability at high speed further and a strengthened inlet cone allowing a service clearance to Mach 2.0 (2,450 km/h; the F.1, F.1A and F.2 were all limited to Mach 1.7 (2,083 km/h). An upgraded A.I.23B radar and new, radar-guided Red Top missiles offered a forward hemisphere attack capability, even though additional electronics meant that the ADEN guns had to be deleted – but they were not popular in their position in front of the windscreen, because the muzzle flash blinded the pilot upon firing. The new engines and fin made the F.3 the highest performance Skyspark yet, but this came at a steep price: higher fuel consumption, resulting in even shorter range. From this basis, a conversion trainer with a side-by-side cockpit, the T.4, was created.
The next interceptor variant was already in development, but there was a need for an interim solution to partially address the F.3's shortcomings, the F.3A. The F.3A introduced two major improvements: a larger, non-jettisonable, 610-imperial-gallon (2,800 L) ventral fuel tank, resulting in a much deeper and longer belly fairing, and a new, kinked, conically cambered wing leading edge. The conically cambered wing improved manoeuvrability, especially at higher altitudes, and it offered space for a slightly larger leading edge fuel tank, raising the total usable internal fuel by 716 imperial gallons (3,260 L). The enlarged ventral tank not only nearly doubled available fuel, it also provided space at its front end for a re-instated pair of 30 mm ADEN cannon with 120 RPG. Alternatively, a retractable pack with unguided 55 mm air-to-air rockets could be installed, or a set of cameras for reconnaissance missions. The F.3A also introduced an improved A.I.23B radar and the new IR-guided Red Top missile, which was much faster and had greater range and manoeuvrability than the Firestreak. Its improved infrared seeker enabled a wider range of engagement angles and offered a forward hemisphere attack capability that would allow the Skyspark to attack even faster bombers (like the new, supersonic Tupolev T-22 Blinder) through a collision-course approach.
Wings and the new belly tank were also immediately incorporated in a second trainer variant, the T.5.
The ultimate variant, the Skyspark F.6, was nearly identical to the F.3A, with the exception that it could carry two additional 260-imperial-gallon (1,200 L) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency and gave the F.6 a substantially improved deployment capability, even though their supersonic drag was so high that the extra fuel would only marginally raise the aircraft’s range when flying beyond the sound barrier for extended periods.
Finally, there was the Skyspark F.2A; it was an early production F.2 upgraded with the new cambered wing, the squared fin, and the 610 imperial gallons (2,800 L) ventral tank. However, the F.2A retained the old AI.23 radar, the IR-guided Firestreak missile and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Skysparks, it had the longest tactical range of all variants, and was used for low-altitude interception over West Germany.
The first Skysparks to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Skyspark for entry into service. The production Skyspark F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Skyspark F.1 entered frontline squadron service with 74 Squadron at Coltishall from 11 July 1960. This made the Skyspark the second Western European-built combat aircraft with true supersonic capability to enter service and the second fully supersonic aircraft to be deployed in Western Europe (the first one in both categories being the Swedish Saab 35 Draken on 8 March 1960 four months earlier).
The aircraft's radar and missiles proved to be effective, and pilots reported that the Skyspark was easy to fly. However, in the first few months of operation the aircraft's serviceability was extremely poor. This was due to the complexity of the aircraft systems and shortages of spares and ground support equipment. Even when the Skyspark was not grounded by technical faults, the RAF initially struggled to get more than 20 flying hours per aircraft per month compared with the 40 flying hours that English Electric believed could be achieved with proper support. In spite of these concerns, within six months of the Skyspark entering service, 74 Squadron was able to achieve 100 flying hours per aircraft.
Deliveries of the slightly improved Skyspark F.1A, with revised avionics and provision for an air-to-air refueling probe, allowed two more squadrons, 56 and 111 Squadron, both based at RAF Wattisham, to convert to the Skyspark in 1960–1961. The Skyspark F.1 was only ordered in limited numbers and served only for a short time; nonetheless, it was viewed as a significant step forward in Britain's air defence capabilities. Following their replacement from frontline duties by the introduction of successively improved Skyspark variants, the remaining F.1 aircraft were employed by the Skyspark Conversion Squadron.
The improved F.2 entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the of the two-seat T.4 and T.5 trainers (based on the F.3 and F.3A/F.6 fighters), which entered service with the Skyspark Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two-seater, small numbers were also allocated to the front-line fighter squadrons. More F.2s were produced than there were available squadron slots, so later production aircraft were stored for years before being used operationally; some of these Skyspark F.2s were converted to F.2As.
The F.3, with more powerful engines and the new Red Top missile was expected to be the definitive Skyspark, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. However, the F.3 also had only a short operational life and was withdrawn from service early due to defence cutbacks and the introduction of the even more capable and longer-range F.6, some of which were converted F.3s.
The introduction of the F.3 and F.6 allowed the RAF to progressively reequip squadrons operating aircraft such as the subsonic Gloster Javelin and retire these types during the mid-1960s. During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Skyspark's range and firepower shortcomings became increasingly apparent. The transfer of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force, alongside those withdrawn from Germany as they were replaced by SEPECAT Jaguars in the ground attack role.
The Skyspark's direct replacement was the Tornado F.3, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Skyspark, including far larger weapons load and considerably more advanced avionics. Skysparks were slowly phased out of service between 1974 and 1988, even though they lasted longer than expected because the definitive Tornado F.3 went through serious teething troubles and its service introduction was delayed several times. In their final years, the Skysparks’ airframes required considerable maintenance to keep them airworthy due to the sheer number of accumulated flight hours.

The kit and its assembly:
This build was a submission to the “Hunter, Lightning, Canberra” group build at whatifmodellers.com, and one of my personal ultimate challenges – a project that you think about very often, but the you put the thought back into its box when you realize that turning this idea into hardware will be a VERY tedious, complex and work-intensive task. But the thematic group build was the perfect occasion to eventually tackle the idea of a model of a “side-by-side engine BAC Lightning”, a.k.a. “Flatning”, as a rather conservative alternative to the real aircraft’s unique and unusual design with stacked engines in the fuselage, which brought a multitude of other design consequences that led to a really unique aircraft.
And it sound so simple: take a Lightning, just change the tail section. But it’s not that simple, because the whole fuselage shape would be different, resulting in less depth, the wings have to be attached somewhere and somehow, the landing gear might have to be adjusted/shortened, and how the fuselage diameter shape changes along the hull, so that you get a more or less smooth shape, was also totally uncertain!
Initially I considered a MiG Ye-152 as a body donor, but that was rejected due to the sheer price of the only available kit (ModelSvit). A Chinese Shenyang J-8I would also have been ideal – but there’s not 1:72 kit of this aircraft around, just of its successor with side intakes, a 1:72 J-8II from trumpeter.
I eventually decided to keep costs low, and I settled for the shaggy PM Model Su-15 (marketed as Su-21) “Flagon” as main body donor: it’s cheap, the engines have a good size for Avons and the pen nib fairing has a certain retro touch that goes well with the Lightning’s Fifties design.
The rest of this "Flatning" came from a Hasegawa 1:72 BAC Lightning F.6 (Revell re-boxing).
Massive modifications were necessary and lots of PSR. In an initial step the Flagon lost its lower wing halves, which are an integral part of the lower fuselage half. The cockpit section was cut away where the intake ducts begin. The Lightning had its belly tank removed (set aside for a potential later re-installation), and dry-fitting and crude measures suggested that only the cockpit section from the Lightning, its spine and the separate fin would make it onto the new fuselage.
Integrating the parts was tough, though! The problem that caused the biggest headaches: how to create a "smooth" fuselage from the Lightning's rounded front end with a single nose intake that originally develops into a narrow, vertical hull, combined with the boxy and rather wide Flagon fuselage with large Phantom-esque intakes? My solution: taking out deep wedges from all (rather massive) hull parts along the intake ducts, bend the leftover side walls inwards and glue them into place, so that the width becomes equal with the Lightning's cockpit section. VERY crude and massive body work!
However, the Lightning's cockpit section for the following hull with stacked engines is much deeper than the Flagon's side-by-side layout. My initial idea was to place the cockpit section higher, but I would have had to transplant a part of the Lightning's upper fuselage (with the spine on top, too!) onto the "flat" Flagon’s back. But this would have looked VERY weird, and I'd have had to bridge the round ventral shape of the Lightning into the boxy Flagon underside, too. This was no viable option, so that the cockpit section had to be further modified; I cut away the whole ventral cockpit section, at the height of the lower intake lip. Similar to my former Austrian Hasegawa Lightning, I also cut away the vertical bulkhead directly behind the intake opening - even though I did not improve the cockpit with a better tub with side consoles. At the back end, the Flagon's jet exhausts were opened and received afterburner dummies inside as a cosmetic upgrade.
Massive PSR work followed all around the hull. The now-open area under the cockpit was filled with lead beads to keep the front wheel down, and I implanted a landing gear well (IIRC, it's from an Xtrakit Swift). With the fuselage literally taking shape, the wings were glued together and the locator holes for the overwing tanks filled, because they would not be mounted.
To mount the wings to the new hull, crude measurements suggested that wedges had to be cut away from the Lightning's wing roots to match the weird fuselage shape. They were then glued to the shoulders, right behind the cockpit due to the reduced fuselage depth. At this stage, the Lightning’s stabilizer attachment points were transplanted, so that they end up in a similar low position on the rounded Su-15 tail. Again, lots of PSR…
At this stage I contemplated the next essential step: belly tank or not? The “Flatning” would have worked without it, but its profile would look rather un-Lightning-ish and rather “flat”. On the other side, a conformal tank would probably look quite strange on the new wide and flat ventral fuselage...? Only experiments could yield an answer, so I glued together the leftover belly bulge parts from the Hasegawa kit and played around with it. I considered a new, wider belly tank, but I guess that this would have looked too ugly. I eventually settled upon the narrow F.6 tank and also used the section behind it with the arrestor hook. I just reduced its depth by ~2 mm, with a slight slope towards the rear because I felt (righteously) that the higher wing position would lower the model’s stance. More massive PSR followed….
Due to the expected poor ground clearance, the Lightning’s stabilizing ventral fins were mounted directly under the fuselage edges rather than on the belly tank. Missile pylons for Red Tops were mounted to the lower front fuselage, similar to the real arrangement, and cable fairings, scratched from styrene profiles, were added to the lower flanks, stretching the hull optically and giving more structure to the hull.
To my surprise, I did not have to shorten the landing gear’s main legs! The wings ended up a little higher on the fuselage than on the original Lightning, and the front wheel sits a bit further back and deeper inside of its donor well, too, so that the fuselage comes probably 2 mm closer to the ground than an OOB Lightning model. Just like on the real aircraft, ground clearance is marginal, but when the main wheels were finally in place, the model turned out to have a low but proper stance, a little F8U-ish.
Painting and markings:
I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.
A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.
After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.
Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.
A major effort, and I have seriously depleted my putty stocks for this build! However, the result looks less spectacular than it actually is: changing a Lightning from its literally original stacked engine layout into a more conservative side-by-side arrangement turned out to be possible, even though the outcome is not really pretty. But it works and is feasible!

Some background:
The OV-10 Bronco was initially conceived in the early 1960s through an informal collaboration between W. H. Beckett and Colonel K. P. Rice, U.S. Marine Corps, who met at Naval Air Weapons Station China Lake, California, and who also happened to live near each other. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations. At the time, the U.S. Army was still experimenting with armed helicopters, and the U.S. Air Force was not interested in close air support.
The concept aircraft was to operate from expedient forward air bases using roads as runways. Speed was to be from very slow to medium subsonic, with much longer loiter times than a pure jet. Efficient turboprop engines would give better performance than piston engines. Weapons were to be mounted on the centerline to get efficient aiming. The inventors favored strafing weapons such as self-loading recoilless rifles, which could deliver aimed explosive shells with less recoil than cannons, and a lower per-round weight than rockets. The airframe was to be designed to avoid the back blast.
Beckett and Rice developed a basic platform meeting these requirements, then attempted to build a fiberglass prototype in a garage. The effort produced enthusiastic supporters and an informal pamphlet describing the concept. W. H. Beckett, who had retired from the Marine Corps, went to work at North American Aviation to sell the aircraft.
The aircraft's design supported effective operations from forward bases. The OV-10 had a central nacelle containing a crew of two in tandem and space for cargo, and twin booms containing twin turboprop engines. The visually distinctive feature of the aircraft is the combination of the twin booms, with the horizontal stabilizer that connected them at the fin tips. The OV-10 could perform short takeoffs and landings, including on aircraft carriers and large-deck amphibious assault ships without using catapults or arresting wires. Further, the OV-10 was designed to take off and land on unimproved sites. Repairs could be made with ordinary tools. No ground equipment was required to start the engines. And, if necessary, the engines would operate on high-octane automobile fuel with only a slight loss of power.
The aircraft had responsive handling and could fly for up to 5½ hours with external fuel tanks. The cockpit had extremely good visibility for both pilot and co-pilot, provided by a wrap-around "greenhouse" that was wider than the fuselage. North American Rockwell custom ejection seats were standard, with many successful ejections during service. With the second seat removed, the OV-10 could carry 3,200 pounds (1,500 kg) of cargo, five paratroopers, or two litter patients and an attendant. Empty weight was 6,969 pounds (3,161 kg). Normal operating fueled weight with two crew was 9,908 pounds (4,494 kg). Maximum takeoff weight was 14,446 pounds (6,553 kg).
The bottom of the fuselage bore sponsons or "stub wings" that improved flight performance by decreasing aerodynamic drag underneath the fuselage. Normally, four 7.62 mm (.308 in) M60C machine guns were carried on the sponsons, accessed through large forward-opening hatches. The sponsons also had four racks to carry bombs, pods, or fuel. The wings outboard of the engines contained two additional hardpoints, one per side. Racked armament in the Vietnam War was usually seven-shot 2.75 in (70 mm) rocket pods with white phosphorus marker rounds or high-explosive rockets, or 5" (127 mm) four-shot Zuni rocket pods. Bombs, ADSIDS air-delivered/para-dropped unattended seismic sensors, Mk-6 battlefield illumination flares, and other stores were also carried.
Operational experience showed some weaknesses in the OV-10's design. It was significantly underpowered, which contributed to crashes in Vietnam in sloping terrain because the pilots could not climb fast enough. While specifications stated that the aircraft could reach 26,000 feet (7,900 m), in Vietnam the aircraft could reach only 18,000 feet (5,500 m). Also, no OV-10 pilot survived ditching the aircraft.
The OV-10 served in the U.S. Air Force, U.S. Marine Corps, and U.S. Navy, as well as in the service of a number of other countries. In U.S. military service, the Bronco was operated until the early Nineties, and obsoleted USAF OV-10s were passed on to the Bureau of Alcohol, Tobacco, and Firearms for anti-drug operations. A number of OV-10As furthermore ended up in the hands of the California Department of Forestry (CDF) and were used for spotting fires and directing fire bombers onto hot spots.
This was not the end of the OV-10 in American military service, though: In 2012, the type gained new attention because of its unique qualities. A $20 million budget was allocated to activate an experimental USAF unit of two airworthy OV-10Gs, acquired from NASA and the State Department. These machines were retrofitted with military equipment and were, starting in May 2015, deployed overseas to support Operation “Inherent Resolve”, flying more than 120 combat sorties over 82 days over Iraq and Syria. Their concrete missions remained unclear, and it is speculated they provided close air support for Special Forces missions, esp. in confined urban environments where the Broncos’ loitering time and high agility at low speed and altitude made them highly effective and less vulnerable than helicopters.
Furthermore, these Broncos reputedly performed strikes with the experimental AGR-20A “Advanced Precision Kill Weapons System (APKWS)”, a Hydra 70-millimeter rocket with a laser-seeking head as guidance - developed for precision strikes against small urban targets with little collateral damage. The experiment ended satisfactorily, but the machines were retired again, and the small unit was dissolved.
However, the machines had shown their worth in asymmetric warfare, and the U.S. Air Force decided to invest in reactivating the OV-10 on a regular basis, despite the overhead cost of operating an additional aircraft type in relatively small numbers – but development and production of a similar new type would have caused much higher costs, with an uncertain time until an operational aircraft would be ready for service. Re-activating a proven design and updating an existing airframe appeared more efficient.
The result became the MV-10H, suitably christened “Super Bronco” but also known as “Black Pony”, after the program's internal name. This aircraft was derived from the official OV-10X proposal by Boeing from 2009 for the USAF's Light Attack/Armed Reconnaissance requirement. Initially, Boeing proposed to re-start OV-10 manufacture, but this was deemed uneconomical, due to the expected small production number of new serial aircraft, so the “Black Pony” program became a modernization project. In consequence, all airframes for the "new" MV-10Hs were recovered OV-10s of various types from the "boneyard" at Davis-Monthan Air Force Base in Arizona.
While the revamped aircraft would maintain much of its 1960s-vintage rugged external design, modernizations included a completely new, armored central fuselage with a highly modified cockpit section, ejection seats and a computerized glass cockpit. The “Black Pony” OV-10 had full dual controls, so that either crewmen could steer the aircraft while the other operated sensors and/or weapons. This feature would also improve survivability in case of incapacitation of a crew member as the result from a hit.
The cockpit armor protected the crew and many vital systems from 23mm shells and shrapnel (e. g. from MANPADS). The crew still sat in tandem under a common, generously glazed canopy with flat, bulletproof panels for reduced sun reflections, with the pilot in the front seat and an observer/WSO behind. The Bronco’s original cargo capacity and the rear door were retained, even though the extra armor and defensive measures like chaff/flare dispensers as well as an additional fuel cell in the central fuselage limited the capacity. However, it was still possible to carry and deploy personnel, e. g. small special ops teams of up to four when the aircraft flew in clean configuration.
Additional updates for the MV-10H included structural reinforcements for a higher AUW and higher g load maneuvers, similar to OV-10D+ standards. The landing gear was also reinforced, and the aircraft kept its ability to operate from short, improvised airstrips. A fixed refueling probe was added to improve range and loiter time.
Intelligence sensors and smart weapon capabilities included a FLIR sensor and a laser range finder/target designator, both mounted in a small turret on the aircraft’s nose. The MV-10H was also outfitted with a data link and the ability to carry an integrated targeting pod such as the Northrop Grumman LITENING or the Lockheed Martin Sniper Advanced Targeting Pod (ATP). Also included was the Remotely Operated Video Enhanced Receiver (ROVER) to provide live sensor data and video recordings to personnel on the ground.
To improve overall performance and to better cope with the higher empty weight of the modified aircraft as well as with operations under hot-and-high conditions, the engines were beefed up. The new General Electric CT7-9D turboprop engines improved the Bronco's performance considerably: top speed increased by 100 mph (160 km/h), the climb rate was tripled (a weak point of early OV-10s despite the type’s good STOL capability) and both take-off as well as landing run were almost halved. The new engines called for longer nacelles, and their circular diameter markedly differed from the former Garrett T76-G-420/421 turboprop engines. To better exploit the additional power and reduce the aircraft’s audio signature, reversible contraprops, each with eight fiberglass blades, were fitted. These allowed a reduced number of revolutions per minute, resulting in less noise from the blades and their tips, while the engine responsiveness was greatly improved. The CT7-9Ds’ exhausts were fitted with muzzlers/air mixers to further reduce the aircraft's noise and heat signature.
Another novel and striking feature was the addition of so-called “tip sails” to the wings: each wingtip was elongated with a small, cigar-shaped fairing, each carrying three staggered, small “feather blade” winglets. Reputedly, this installation contributed ~10% to the higher climb rate and improved lift/drag ratio by ~6%, improving range and loiter time, too.
Drawing from the Iraq experience as well as from the USMC’s NOGS test program with a converted OV-10D as a night/all-weather gunship/reconnaissance platform, the MV-10H received a heavier gun armament: the original four light machine guns that were only good for strafing unarmored targets were deleted and their space in the sponsons replaced by avionics. Instead, the aircraft was outfitted with a lightweight M197 three-barrel 20mm gatling gun in a chin turret. This could be fixed in a forward position at high speed or when carrying forward-firing ordnance under the stub wings, or it could be deployed to cover a wide field of fire under the aircraft when it was flying slower, being either slaved to the FLIR or to a helmet sighting auto targeting system.
The original seven hardpoints were retained (1x ventral, 2x under each sponson, and another pair under the outer wings), but the total ordnance load was slightly increased and an additional pair of launch rails for AIM-9 Sidewinders or other light AAMs under the wing tips were added – not only as a defensive measure, but also with an anti-helicopter role in mind; four more Sidewinders could be carried on twin launchers under the outer wings against aerial targets. Other guided weapons cleared for the MV-10H were the light laser-guided AGR-20A and AGM-119 Hellfire missiles, the Advanced Precision Kill Weapon System upgrade to the light Hydra 70 rockets, the new Laser Guided Zuni Rocket which had been cleared for service in 2010, TV-/IR-/laser-guided AGM-65 Maverick AGMs and AGM-122 Sidearm anti-radar missiles, plus a wide range of gun and missile pods, iron and cluster bombs, as well as ECM and flare/chaff pods, which were not only carried defensively, but also in order to disrupt enemy ground communication.
In this configuration, a contract for the conversion of twelve mothballed American Broncos to the new MV-10H standard was signed with Boeing in 2016, and the first MV-10H was handed over to the USAF in early 2018, with further deliveries lasting into early 2020. All machines were allocated to the newly founded 919th Special Operations Support Squadron at Duke Field (Florida). This unit was part of the 919th Special Operations Wing, an Air Reserve Component (ARC) of the United States Air Force. It was assigned to the Tenth Air Force of Air Force Reserve Command and an associate unit of the 1st Special Operations Wing, Air Force Special Operations Command (AFSOC). If mobilized the wing was gained by AFSOC (Air Force Special Operations Command) to support Special Tactics, the U.S. Air Force's special operations ground force. Similar in ability and employment to Marine Special Operations Command (MARSOC), U.S. Army Special Forces and U.S. Navy SEALs, Air Force Special Tactics personnel were typically the first to enter combat and often found themselves deep behind enemy lines in demanding, austere conditions, usually with little or no support.
The MV-10Hs are expected to provide support for these ground units in the form of all-weather reconnaissance and observation, close air support and also forward air control duties for supporting ground units. Precision ground strikes and protection from enemy helicopters and low-flying aircraft were other, secondary missions for the modernized Broncos, which are expected to serve well into the 2040s. Exports or conversions of foreign OV-10s to the Black Pony standard are not planned, though.

The kit and its assembly:
This fictional Bronco update/conversion was simply spawned by the idea: could it be possible to replace the original cockpit section with one from an AH-1 Cobra, for a kind of gunship version?
The basis is the Academy OV-10D kit, mated with the cockpit section from a Fujimi AH-1S TOW Cobra (Revell re-boxing, though), chosen because of its “boxy” cockpit section with flat glass panels – I think that it conveys the idea of an armored cockpit section best. Combining these parts was not easy, though, even though the plan sound simple. Initially, the Bronco’s twin booms, wings and stabilizer were built separately, because this made PSR on these sections easier than trying the same on a completed airframe. One of the initial challenges: the different engines. I wanted something uprated, and a different look, and I had a pair of (excellent!) 1:144 resin engines from the Russian company Kompakt Zip for a Tu-95 bomber at hand, which come together with movable(!) eight-blade contraprops that were an almost perfect size match for the original three-blade props. Biggest problem: the Tu-95 nacelles have a perfectly circular diameter, while the OV-10’s booms are square and rectangular. Combining these parts and shapes was already a messy PST affair, but it worked out quite well – even though the result rather reminds of some Chinese upgrade measure (anyone know the Tu-4 copies with turboprops? This here looks similar!). But while not pretty, I think that the beafier look works well and adds to the idea of a “revived” aircraft. And you can hardly beat the menacing look of contraprops on anything...
The exotic, so-called “tip sails” on the wings, mounted on short booms, are a detail borrowed from the Shijiazhuang Y-5B-100, an updated Chinese variant/copy of the Antonov An-2 biplane transporter. The booms are simple pieces of sprue from the Bronco kit, the winglets were cut from 0.5mm styrene sheet.
For the cockpit donor, the AH-1’s front section was roughly built, including the engine section (which is a separate module, so that the basic kit can be sold with different engine sections), and then the helicopter hull was cut and trimmed down to match the original Bronco pod and to fit under the wing. This became more complicated than expected, because a) the AH-1 cockpit and the nose are considerably shorter than the OV-10s, b) the AH-1 fuselage is markedly taller than the Bronco’s and c) the engine section, which would end up in the area of the wing, features major recesses, making the surface very uneven – calling for massive PSR to even this out. PSR was also necessary to hide the openings for the Fujimi AH-1’s stub wings. Other issues: the front landing gear (and its well) had to be added, as well as the OV-10 wing stubs. Furthermore, the new cockpit pod’s rear section needed an aerodynamical end/fairing, but I found a leftover Academy OV-10 section from a build/kitbashing many moons ago. Perfect match!
All these challenges could be tackled, even though the AH-1 cockpit looks surprisingly stout and massive on the Bronco’s airframe - the result looks stockier than expected, but it works well for the "Gunship" theme. Lots of PSR went into the new central fuselage section, though, even before it was mated with the OV-10 wing and the rest of the model.
Once cockpit and wing were finally mated, the seams had to disappear under even more PSR and a spinal extension of the canopy had to be sculpted across the upper wing surface, which would meld with the pod’s tail in a (more or less) harmonious shape. Not an easy task, and the fairing was eventually sculpted with 2C putty, plus even more PSR… Looks quite homogenous, though.
After this massive body work, other hardware challenges appeared like small distractions. The landing gear was another major issue because the deeper AH-1 section lowered the ground clearance, also because of the chin turret. To counter this, I raised the OV-10’s main landing gear by ~2mm – not much, but it was enough to create a credible stance, together with the front landing gear transplant under the cockpit, which received an internal console to match the main landing gear’s length. Due to the chin turret and the shorter nose, the front wheel retracts backwards now. But this looks quite plausible, thanks to the additional space under the cockpit tub, which also made a belt feed for the gun’s ammunition supply believable.
To enhance the menacing look I gave the model a fixed refueling boom, made from 1mm steel wire and a receptor adapter sculpted with white glue. The latter stuff was also used add some antenna fairings around the hull. Some antennae, chaff dispensers and an IR decoy were taken from the Academy kit.
The ordnance came from various sources. The Sidewinders under the wing tips were taken from an Italeri F-16C/D kit, they look better than the missiles from the Academy Bronco kit. Their launch rails came from an Italeri Bae Hawk 200. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-10 and -19 missile pods on the stub wings were taken from the OV-10 kit.
Painting and markings:
Finding a suitable and somewhat interesting – but still plausible – paint scheme was not easy. Taking the A-10 as benchmark, an overall light grey livery (with focus on low contrast against the sky as protection against ground fire) would have been a likely choice – and in fact the last operational American OV-10s were painted in this fashion. But in order to provide a different look I used the contemporary USAF V-22Bs and Special Operations MC-130s as benchmark, which typically carry a darker paint scheme consisting of FS 36118 (suitably “Gunship Gray” :D) from above, FS 36375 underneath, with a low, wavy waterline, plus low-viz markings. Not spectacular, but plausible – and very similar to the late r/w Colombian OV-10s.
The cockpit tub became Dark Gull Grey (FS 36231, Humbrol 140) and the landing gear white (Revell 301).
The model received an overall black ink washing and some post-panel-shading, to liven up the dull all-grey livery. The decals were gathered from various sources, and I settled for black USAF low-viz markings. The “stars and bars” come from a late USAF F-4, the “IP” tail code was tailored from F-16 markings and the shark mouth was taken from an Academy AH-64. Most stencils came from another Academy OV-10 sheet and some other sources.
Decals were also used to create the trim on the propeller blades and markings on the ordnance.
Finally, the model was sealed with a coat of matt acrylic varnish (Italeri) and some exhaust soot stains were added with graphite along the tail boom flanks.
A successful transplantation – but is this still a modified Bronco or already a kitbashing? The result looks quite plausible and menacing, even though the TOW Cobra front section appears relatively massive. But thanks to the bigger engines and extended wing tips the proportions still work. The large low-pressure tires look a bit goofy under the aircraft, but they are original. The grey livery works IMHO well, too – a more colorful or garish scheme would certainly have distracted from the modified technical basis.
W&W 120 has had a colorful life...
Being built in December of 1957 as Pennsylvania Railroad ALCO RS11 #8647, it then survived into Penn Central, being renumbered to 7647. Once more, originally PRR 8647, now PC 7647 survived into Conrail and retaining its PC number, became CR 7647
CR 7647 was converted into an MT4 slug sometime between 1977 and 1991 and renumbered to CR 1020.
It was then sold off to the Winchester and Western sometime between August of 1994 and January of 1995.
Another interesting feature is the SW1500 cab on top of the slug...which was performed sometime between December of 2003 and November of 2005. The cab is off of an IHB SW1500 (as to which SW1500, I don't not know - yet)
Here, in 2013 we now see that the engine is sitting within the confines of the Unimin Corporation just up the road from the engine facility at Gore, VA. Which is a sand mining business and one of the leading producers of non metallic minerals.

Nothing you see here is real, even though the conversion or the presented background story might be based on authentic facts. BEWARE!
Some background:
The English Electric Skyspark was a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2. The Skyspark was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Skyspark.
The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 program. W.E.W. "Teddy" Petter, formerly chief designer at Westland Aircraft, was a keen early proponent of Britain's need to develop a supersonic fighter aircraft. In 1947, Petter approached the Ministry of Supply (MoS) with his proposal, and in response Specification ER.103 was issued for a single research aircraft, which was to be capable of flight at Mach 1.5 (1,593 km/h) and 50,000 ft (15,000 m).
Petter initiated a design proposal with F W "Freddie" Page leading the design and Ray Creasey responsible for the aerodynamics. As it was designed for Mach 1.5, it had a 40° swept wing to keep the leading edge clear of the Mach cone. To mount enough power into the airframe, two engines were installed, in an unusual, stacked layout and with a high tailplane This proposal was submitted in November 1948, and in January 1949 the project was designated P.1 by English Electric. On 29 March 1949 MoS granted approval to start the detailed design, develop wind tunnel models and build a full-size mock-up.
The design that had developed during 1948 evolved further during 1949 to further improve performance. To achieve Mach 2 the wing sweep was increased to 60° with the ailerons moved to the wingtips. In late 1949, low-speed wind tunnel tests showed that a vortex was generated by the wing which caused a large downwash on the initial high tailplane; this issue was solved by lowering the tail below the wing. Following the resignation of Petter, Page took over as design team leader for the P.1. In 1949, the Ministry of Supply had issued Specification F23/49, which expanded upon the scope of ER103 to include fighter-level manoeuvring. On 1 April 1950, English Electric received a contract for two flying airframes, as well as one static airframe, designated P.1.
The Royal Aircraft Establishment disagreed with Petter's choice of sweep angle (60 degrees) and the stacked engine layout, as well as the low tailplane position, was considered to be dangerous, too. To assess the effects of wing sweep and tailplane position on the stability and control of Petter's design Short Brothers were issued a contract, by the Ministry of Supply, to produce the Short SB.5 in mid-1950. This was a low-speed research aircraft that could test sweep angles from 50 to 69 degrees and tailplane positions high or low. Testing with the wings and tail set to the P.1 configuration started in January 1954 and confirmed this combination as the correct one. The proposed 60-degree wing sweep was retained, but the stacked engines had to give way to a more conventional configuration with two engines placed side-by-side in the tail, but still breathing through a mutual nose air intake.
From 1953 onward, the first three prototype aircraft were hand-built at Samlesbury. These aircraft had been assigned the aircraft serials WG760, WG763, and WG765 (the structural test airframe). The prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, as the selected Rolls-Royce Avon engines had fallen behind schedule due to their own development problems. Since there was not much space in the fuselage for fuel, the thin wings became the primary fuel tanks and since they also provided space for the stowed main undercarriage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance. The narrow tires housed in the thin wings rapidly wore out if there was any crosswind component during take-off or landing. Outwardly, the prototypes looked very much like the production series, but they were distinguished by the rounded-triangular air intake with no center-body at the nose, short fin, and lack of operational equipment.
On 9 June 1952, it was decided that there would be a second phase of prototypes built to develop the aircraft toward achieving Mach 2.0 (2,450 km/h); these were designated P.1B while the initial three prototypes were retroactively reclassified as P.1A. P.1B was a significant improvement on P.1A. While it was similar in aerodynamics, structure and control systems, it incorporated extensive alterations to the forward fuselage, reheated Rolls Royce Avon R24R engines, a conical center body inlet cone, variable nozzle reheat and provision for weapons systems integrated with the ADC and AI.23 radar. Three P.1B prototypes were built, assigned serials XA847, XA853 and XA856.
In May 1954, WG760 and its support equipment were moved to RAF Boscombe Down for pre-flight ground taxi trials; on the morning of 4 August 1954, WG760 flew for the first time from Boscombe Down. One week later, WG760 officially achieved supersonic flight for the first time, having exceeded the speed of sound during its third flight. While WG760 had proven the P.1 design to be viable, it was plagued by directional stability problems and a dismal performance: Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of just 48,000 ft (14,630 m), far below the requirements.
To solve the problem and save the P.1, Petter embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed a new, narrower canopy, a revised air intake, a pair of stabilizing fins under the rear fuselage, and a shallow ventral fairing at the wings’ trailing edge that not only reduced the drag coefficient along the wing/fuselage intersection, it also provided space for additional fuel.
On 4 April 1957 the modified P.1B (XA847) made the first flight, immediately exceeding Mach 1. During the early flight trials of the P.1B, speeds in excess of 1,000 mph were achieved daily.
In late October 1958, the plane was officially presented. The event was celebrated in traditional style in a hangar at Royal Aircraft Establishment (RAE) Farnborough, with the prototype XA847 having the name ‘Skyspark’ freshly painted on the nose in front of the RAF Roundel, which almost covered it. A bottle of champagne was put beside the nose on a special rig which allowed the bottle to safely be smashed against the side of the aircraft.
On 25 November 1958 the P.1B XA847 reached Mach 2 for the first time. This made it the second Western European aircraft to reach Mach 2, the first one being the French Dassault Mirage III just over a month earlier on 24 October 1958
The first operational Skyspark, designated Skyspark F.1, was designed as a pure interceptor to defend the V Force airfields in conjunction with the "last ditch" Bristol Bloodhound missiles located either at the bomber airfield, e.g. at RAF Marham, or at dedicated missile sites near to the airfield, e.g. at RAF Woodhall Spa near the Vulcan station RAF Coningsby. The bomber airfields, along with the dispersal airfields, would be the highest priority targets in the UK for enemy nuclear weapons. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range – originally a radius of operation of only 150 miles (240 km) from the V bomber airfields was specified – and endurance. Armament consisted of a pair of 30 mm ADEN cannon in front of the cockpit, and two pylons for IR-guided de Havilland Firestreak air-to-air missiles were added to the lower fuselage flanks. These hardpoints could, alternatively, carry pods with unguided 55 mm air-to-air rockets. The Ferranti AI.23 onboard radar provided missile guidance and ranging, as well as search and track functions.
The next two Skyspark variants, the Skyspark F.1A and F.2, incorporated relatively minor design changes, but for the next variant, the Skyspark F.3, they were more extensive: The F.3 had higher thrust Rolls-Royce Avon 301R engines, a larger squared-off fin that improved directional stability at high speed further and a strengthened inlet cone allowing a service clearance to Mach 2.0 (2,450 km/h; the F.1, F.1A and F.2 were all limited to Mach 1.7 (2,083 km/h). An upgraded A.I.23B radar and new, radar-guided Red Top missiles offered a forward hemisphere attack capability, even though additional electronics meant that the ADEN guns had to be deleted – but they were not popular in their position in front of the windscreen, because the muzzle flash blinded the pilot upon firing. The new engines and fin made the F.3 the highest performance Skyspark yet, but this came at a steep price: higher fuel consumption, resulting in even shorter range. From this basis, a conversion trainer with a side-by-side cockpit, the T.4, was created.
The next interceptor variant was already in development, but there was a need for an interim solution to partially address the F.3's shortcomings, the F.3A. The F.3A introduced two major improvements: a larger, non-jettisonable, 610-imperial-gallon (2,800 L) ventral fuel tank, resulting in a much deeper and longer belly fairing, and a new, kinked, conically cambered wing leading edge. The conically cambered wing improved manoeuvrability, especially at higher altitudes, and it offered space for a slightly larger leading edge fuel tank, raising the total usable internal fuel by 716 imperial gallons (3,260 L). The enlarged ventral tank not only nearly doubled available fuel, it also provided space at its front end for a re-instated pair of 30 mm ADEN cannon with 120 RPG. Alternatively, a retractable pack with unguided 55 mm air-to-air rockets could be installed, or a set of cameras for reconnaissance missions. The F.3A also introduced an improved A.I.23B radar and the new IR-guided Red Top missile, which was much faster and had greater range and manoeuvrability than the Firestreak. Its improved infrared seeker enabled a wider range of engagement angles and offered a forward hemisphere attack capability that would allow the Skyspark to attack even faster bombers (like the new, supersonic Tupolev T-22 Blinder) through a collision-course approach.
Wings and the new belly tank were also immediately incorporated in a second trainer variant, the T.5.
The ultimate variant, the Skyspark F.6, was nearly identical to the F.3A, with the exception that it could carry two additional 260-imperial-gallon (1,200 L) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency and gave the F.6 a substantially improved deployment capability, even though their supersonic drag was so high that the extra fuel would only marginally raise the aircraft’s range when flying beyond the sound barrier for extended periods.
Finally, there was the Skyspark F.2A; it was an early production F.2 upgraded with the new cambered wing, the squared fin, and the 610 imperial gallons (2,800 L) ventral tank. However, the F.2A retained the old AI.23 radar, the IR-guided Firestreak missile and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Skysparks, it had the longest tactical range of all variants, and was used for low-altitude interception over West Germany.
The first Skysparks to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Skyspark for entry into service. The production Skyspark F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Skyspark F.1 entered frontline squadron service with 74 Squadron at Coltishall from 11 July 1960. This made the Skyspark the second Western European-built combat aircraft with true supersonic capability to enter service and the second fully supersonic aircraft to be deployed in Western Europe (the first one in both categories being the Swedish Saab 35 Draken on 8 March 1960 four months earlier).
The aircraft's radar and missiles proved to be effective, and pilots reported that the Skyspark was easy to fly. However, in the first few months of operation the aircraft's serviceability was extremely poor. This was due to the complexity of the aircraft systems and shortages of spares and ground support equipment. Even when the Skyspark was not grounded by technical faults, the RAF initially struggled to get more than 20 flying hours per aircraft per month compared with the 40 flying hours that English Electric believed could be achieved with proper support. In spite of these concerns, within six months of the Skyspark entering service, 74 Squadron was able to achieve 100 flying hours per aircraft.
Deliveries of the slightly improved Skyspark F.1A, with revised avionics and provision for an air-to-air refueling probe, allowed two more squadrons, 56 and 111 Squadron, both based at RAF Wattisham, to convert to the Skyspark in 1960–1961. The Skyspark F.1 was only ordered in limited numbers and served only for a short time; nonetheless, it was viewed as a significant step forward in Britain's air defence capabilities. Following their replacement from frontline duties by the introduction of successively improved Skyspark variants, the remaining F.1 aircraft were employed by the Skyspark Conversion Squadron.
The improved F.2 entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the of the two-seat T.4 and T.5 trainers (based on the F.3 and F.3A/F.6 fighters), which entered service with the Skyspark Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two-seater, small numbers were also allocated to the front-line fighter squadrons. More F.2s were produced than there were available squadron slots, so later production aircraft were stored for years before being used operationally; some of these Skyspark F.2s were converted to F.2As.
The F.3, with more powerful engines and the new Red Top missile was expected to be the definitive Skyspark, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. However, the F.3 also had only a short operational life and was withdrawn from service early due to defence cutbacks and the introduction of the even more capable and longer-range F.6, some of which were converted F.3s.
The introduction of the F.3 and F.6 allowed the RAF to progressively reequip squadrons operating aircraft such as the subsonic Gloster Javelin and retire these types during the mid-1960s. During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Skyspark's range and firepower shortcomings became increasingly apparent. The transfer of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force, alongside those withdrawn from Germany as they were replaced by SEPECAT Jaguars in the ground attack role.
The Skyspark's direct replacement was the Tornado F.3, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Skyspark, including far larger weapons load and considerably more advanced avionics. Skysparks were slowly phased out of service between 1974 and 1988, even though they lasted longer than expected because the definitive Tornado F.3 went through serious teething troubles and its service introduction was delayed several times. In their final years, the Skysparks’ airframes required considerable maintenance to keep them airworthy due to the sheer number of accumulated flight hours.

The kit and its assembly:
This build was a submission to the “Hunter, Lightning, Canberra” group build at whatifmodellers.com, and one of my personal ultimate challenges – a project that you think about very often, but the you put the thought back into its box when you realize that turning this idea into hardware will be a VERY tedious, complex and work-intensive task. But the thematic group build was the perfect occasion to eventually tackle the idea of a model of a “side-by-side engine BAC Lightning”, a.k.a. “Flatning”, as a rather conservative alternative to the real aircraft’s unique and unusual design with stacked engines in the fuselage, which brought a multitude of other design consequences that led to a really unique aircraft.
And it sound so simple: take a Lightning, just change the tail section. But it’s not that simple, because the whole fuselage shape would be different, resulting in less depth, the wings have to be attached somewhere and somehow, the landing gear might have to be adjusted/shortened, and how the fuselage diameter shape changes along the hull, so that you get a more or less smooth shape, was also totally uncertain!
Initially I considered a MiG Ye-152 as a body donor, but that was rejected due to the sheer price of the only available kit (ModelSvit). A Chinese Shenyang J-8I would also have been ideal – but there’s not 1:72 kit of this aircraft around, just of its successor with side intakes, a 1:72 J-8II from trumpeter.
I eventually decided to keep costs low, and I settled for the shaggy PM Model Su-15 (marketed as Su-21) “Flagon” as main body donor: it’s cheap, the engines have a good size for Avons and the pen nib fairing has a certain retro touch that goes well with the Lightning’s Fifties design.
The rest of this "Flatning" came from a Hasegawa 1:72 BAC Lightning F.6 (Revell re-boxing).
Massive modifications were necessary and lots of PSR. In an initial step the Flagon lost its lower wing halves, which are an integral part of the lower fuselage half. The cockpit section was cut away where the intake ducts begin. The Lightning had its belly tank removed (set aside for a potential later re-installation), and dry-fitting and crude measures suggested that only the cockpit section from the Lightning, its spine and the separate fin would make it onto the new fuselage.
Integrating the parts was tough, though! The problem that caused the biggest headaches: how to create a "smooth" fuselage from the Lightning's rounded front end with a single nose intake that originally develops into a narrow, vertical hull, combined with the boxy and rather wide Flagon fuselage with large Phantom-esque intakes? My solution: taking out deep wedges from all (rather massive) hull parts along the intake ducts, bend the leftover side walls inwards and glue them into place, so that the width becomes equal with the Lightning's cockpit section. VERY crude and massive body work!
However, the Lightning's cockpit section for the following hull with stacked engines is much deeper than the Flagon's side-by-side layout. My initial idea was to place the cockpit section higher, but I would have had to transplant a part of the Lightning's upper fuselage (with the spine on top, too!) onto the "flat" Flagon’s back. But this would have looked VERY weird, and I'd have had to bridge the round ventral shape of the Lightning into the boxy Flagon underside, too. This was no viable option, so that the cockpit section had to be further modified; I cut away the whole ventral cockpit section, at the height of the lower intake lip. Similar to my former Austrian Hasegawa Lightning, I also cut away the vertical bulkhead directly behind the intake opening - even though I did not improve the cockpit with a better tub with side consoles. At the back end, the Flagon's jet exhausts were opened and received afterburner dummies inside as a cosmetic upgrade.
Massive PSR work followed all around the hull. The now-open area under the cockpit was filled with lead beads to keep the front wheel down, and I implanted a landing gear well (IIRC, it's from an Xtrakit Swift). With the fuselage literally taking shape, the wings were glued together and the locator holes for the overwing tanks filled, because they would not be mounted.
To mount the wings to the new hull, crude measurements suggested that wedges had to be cut away from the Lightning's wing roots to match the weird fuselage shape. They were then glued to the shoulders, right behind the cockpit due to the reduced fuselage depth. At this stage, the Lightning’s stabilizer attachment points were transplanted, so that they end up in a similar low position on the rounded Su-15 tail. Again, lots of PSR…
At this stage I contemplated the next essential step: belly tank or not? The “Flatning” would have worked without it, but its profile would look rather un-Lightning-ish and rather “flat”. On the other side, a conformal tank would probably look quite strange on the new wide and flat ventral fuselage...? Only experiments could yield an answer, so I glued together the leftover belly bulge parts from the Hasegawa kit and played around with it. I considered a new, wider belly tank, but I guess that this would have looked too ugly. I eventually settled upon the narrow F.6 tank and also used the section behind it with the arrestor hook. I just reduced its depth by ~2 mm, with a slight slope towards the rear because I felt (righteously) that the higher wing position would lower the model’s stance. More massive PSR followed….
Due to the expected poor ground clearance, the Lightning’s stabilizing ventral fins were mounted directly under the fuselage edges rather than on the belly tank. Missile pylons for Red Tops were mounted to the lower front fuselage, similar to the real arrangement, and cable fairings, scratched from styrene profiles, were added to the lower flanks, stretching the hull optically and giving more structure to the hull.
To my surprise, I did not have to shorten the landing gear’s main legs! The wings ended up a little higher on the fuselage than on the original Lightning, and the front wheel sits a bit further back and deeper inside of its donor well, too, so that the fuselage comes probably 2 mm closer to the ground than an OOB Lightning model. Just like on the real aircraft, ground clearance is marginal, but when the main wheels were finally in place, the model turned out to have a low but proper stance, a little F8U-ish.
Painting and markings:
I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.
A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.
After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.
Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.
A major effort, and I have seriously depleted my putty stocks for this build! However, the result looks less spectacular than it actually is: changing a Lightning from its literally original stacked engine layout into a more conservative side-by-side arrangement turned out to be possible, even though the outcome is not really pretty. But it works and is feasible!

Some background:
The Bell XP-68A owed its existence to the manufacturer’s rather disappointing outcome of its first jet fighter design, the XP-59A Airacomet. The Airacomet was a twin jet-engined fighter aircraft, designed and built during World War II after Major General Henry H. "Hap" Arnold became aware of the United Kingdom's jet program when he attended a demonstration of the Gloster E.28/39 in April 1941. He requested, and was given, the plans for the aircraft's powerplant, the Power Jets W.1, which he took back to the U.S. He also arranged for an example of the engine, the Whittle W.1X turbojet, to be flown to the U.S., along with drawings for the more powerful W.2B/23 engine and a small team of Power Jets engineers. On 4 September 1941, he offered the U.S. company General Electric a contract to produce an American version of the engine, which subsequently became the General Electric I-A. On the following day, he approached Lawrence Dale Bell, head of Bell Aircraft Corporation, to build a fighter to utilize it. As a disinformation tactic, the USAAF gave the project the designation "P-59A", to suggest it was a development of the unrelated, canceled Bell XP-59 fighter project. The P-59A was the first design fighter to have its turbojet engine and air inlet nacelles integrated within the main fuselage. The jet aircraft’s design was finalized on 9 January 1942 and the first prototype flew in October of the same year.
The following 13 service test YP-59As had a more powerful engine than their predecessor, the General Electric J31, but the improvement in performance was negligible, with top speed increased by only 5 mph and a slight reduction in the time they could be used before an overhaul was needed. One of these aircraft, the third YP-59A, was supplied to the Royal Air Force, in exchange for the first production Gloster Meteor I for evaluation and flight-offs with domestic alternatives.
British pilots found that the YP-59A compared very unfavorably with the jets that they were already flying. The United States Army Air Forces were not impressed by its performance either and cancelled the contract when fewer than half of the originally ordered aircraft had been produced. No P-59s entered combat, but the type paved the way for the next design generation of U.S. turbojet-powered aircraft and helped to develop appropriate maintenance structures and procedures.
In the meantime, a new, more powerful jet engine had been developed in Great Britain, the Halford H-1, which became later better known as the De Havilland Goblin. It was another centrifugal compressor design, but it produced almost twice as much thrust as the XP-59A’s J31 engines. Impressed by the British Gloster Meteor during the USAAF tests at Muroc Dry Lake - performance-wise as well as by the aircraft’s simplicity and ruggedness - Bell reacted promptly and proposed an alternative fighter with wing-mounted engine nacelles, since the XP-59A’s layout had proven to be aerodynamically sub-optimal and unsuited for the installation of H-1 engines. In order to save development time and because the aircraft was rather regarded as a proof-of-concept demonstrator instead of a true fighter prototype, the new aircraft was structurally based on Bell’s current piston-engine P-63 “Kingcobra”. The proposal was accepted and, in order to maintain secrecy, the new jet aircraft inherited once more a designation of a recently cancelled project, this time from the Vultee XP-68 “Tornado” fighter. Similar to the Airacomet two years before, just a simple “A” suffix was added.
Bell’s development contract covered only three XP-68A aircraft. The H-1 units were directly imported from Great Britain in secrecy, suspended in the bomb bays of B-24 Liberator bombers. A pair of these engines was mounted in mid-wing nacelles, very similar to the Gloster Meteor’s arrangement. The tailplane was given a 5° dihedral to move it out of the engine exhaust. In order to bear the new engines and their power, the wing main spars were strengthened and the main landing gear wells were moved towards the aircraft’s centerline, effectively narrowing track width. The landing gear wells now occupied the space of the former radiator ducts for the P-63’s omitted Allison V-1710 liquid-cooled V12 engine. Its former compartment behind the cockpit was used for a new fuel tank and test equipment. Having lost the propeller and its long drive shaft, the nose section was also redesigned: the front fuselage became deeper and the additional space there was used for another fuel tank in front of the cockpit and a bigger weapon bay. Different armament arrangements were envisioned, one of each was to be tested on the three prototypes: one machine would be armed with six 0.5” machine guns, another with four 20mm Hispano M2 cannon, and the third with two 37mm M10 cannon and two 0.5” machine guns. Provisions for a ventral hardpoint for a single drop tank or a 1.000 lb (550 kg) bomb were made, but this was never fitted on any of the prototypes. Additional hardpoints under the outer wings for smaller bombs or unguided missiles followed the same fate.
The three XP-68As were built at Bell’s Atlanta plant in the course of early 1944 and semi-officially christened “Airagator”. After their clandestine transfer to Muroc Dry Lake for flight tests and evaluations, the machines were quickly nicknamed “Barrelcobra” by the test staff – not only because of the characteristic shape of the engine nacelles, but also due to the sheer weight of the machines and their resulting sluggish handling on the ground and in the air. “Cadillac” was another nickname, due to the very soft acceleration through the new jet engines and the lack of vibrations that were typical for piston-engine- and propeller-driven aircraft.
Due to the structural reinforcements and modifications, the XP-68A had become a heavy aircraft with an empty weight of 4 tons and a MTOW of almost 8 tons – the same as the big P-47 Thunderbolt piston fighter, while the P-63 had an MTOW of only 10,700 lb (4,900 kg). The result was, among other flaws, a very long take-off distance, especially in the hot desert climate of the Mojave Desert (which precluded any external ordnance) and an inherent unwillingness to change direction, its turning radius was immense. More than once the brakes overheated during landing, so that extra water cooling for the main landing gear was retrofitted.
Once in the air, the aircraft proved to be quite fast – as long as it was flying in a straight line, though. Only the roll characteristics were acceptable, but flying the XP-68A remained hazardous, esp. after the loss of one of the H-1s engines: This resulted in heavily asymmetrical propulsion, making the XP-68A hard to control at all and prone to spin in level flight.
After trials and direct comparison, the XP-68A turned out not to be as fast and, even worse, much less agile than the Meteor Mk III (the RAF’s then current, operational fighter version), which even had weaker Derwent engines. The operational range was insufficient, too, esp. in regard of the planned Pacific theatre of operations, and the high overall weight precluded any considerable external load like drop tanks.
However, compared with the XP-59A, the XP-68A was a considerable step forward, but it had become quickly clear that the XP-68A and its outfit-a-propeller-design-with jet-engines approach did not bear the potential for any service fighter development: it was already outdated when the prototypes were starting their test program. No further XP-68A was ordered or built, and the three prototypes fulfilled their test and evaluation program until May 1945. During these tests, the first prototype was lost on the ground due to an engine fire. After the program’s completion, the two remaining machines were handed over to the US Navy and used for research at the NATC Patuxent River Test Centre, where they were operated until 1949 and finally scrapped.

The kit and its assembly:
This whiffy Kingcobra conversion was spawned by a post by fellow user nighthunter in January 2019 at whatifmodelers.com about a potential jet-powered variant. In found the idea charming, since the XP-59 had turned out to be a dud and the Gloster Meteor had been tested by the USAAF. Why not combine both into a fictional, late WWII Bell prototype?
The basic idea was simple: take a P-63 and add a Meteor’s engine nacelles, while keeping the Kingcobra’s original proportions. This sounds pretty easy but was more challenging than the first look at the outcome might suggest.
The donor kits are a vintage Airfix 1:72 Gloster Meteor Mk.III, since it has the proper, small nacelles, and an Eastern Express P-63 Kingcobra. The latter looked promising, since this kit comes with very good surface and cockpit details (even with a clear dashboard) as well as parts for several P-63 variants, including the A, C and even the exotic “pinball” manned target version. However, anything comes at a price, and the kit’s low price point is compensated by soft plastic (which turned out to be hard to sand), some flash and mediocre fit of any of the major components like fuselage halves, the wings or the clear parts. It feels a lot like a typical short-run kit. Nevertheless, I feel inclined to build another one in a more conventional fashion some day.
Work started with the H-1 nacelles, which had to be cut out from the Meteor wings. Since they come OOB only with a well-visible vertical plate and a main wing spar dummy in the air intake, I added some fine mesh to the plate – normally, you can see directly onto the engine behind the wing spar. Another issue was the fact that the Meteor’s wings are much thicker and deeper than the P-63s, so that lots of PSR work was necessary.
Simply cutting the P-63 OOB wings up and inserting the Meteor nacelles was also not possible: the P-63 has a very wide main landing gear, due to the ventral radiators and oil coolers, which were originally buried in the wing roots and under the piston engine. The only solution: move the complete landing gear (including the wells) inward, so that the nacelles could be placed as close as possible to the fuselage in a mid-span position. Furthermore, the - now useless - radiator openings had to disappear, resulting in a major redesign of the wing root sections. All of this became a major surgery task, followed by similarly messy work on the outer wings during the integration of the Meteor nacelles. LOTS of PSR, even though the outcome looks surprisingly plausible and balanced.
Work on the fuselage started in parallel. It was built mainly OOB, using the optional ventral fin for a P-63C. The exhaust stubs as well as the dorsal carburetor intake had to disappear (the latter made easy thanks to suitable optional parts for the manned target version). Since the P-63 had a conventional low stabilizer arrangement (unlike the Meteor with its cruciform tail), I gave them a slight dihedral to move them out of the engine efflux, a trick Sukhoi engineers did on the Su-11 prototype with afterburner engines in 1947, too.
Furthermore, the whole nose ahead of the cockpit was heavily re-designed, because I wanted the “new” aircraft to lose its propeller heritage and the P-63’s round and rather pointed nose. Somewhat inspired by the P-59 and the P-80, I omitted the propeller parts altogether and re-sculpted the nose with 2C putty, creating a deeper shape with a tall, oval diameter, so that the lower fuselage line was horizontally extended forward. In a profile view the aircraft now looks much more massive and P-80esque. The front landing gear was retained, just its side walls were extended downwards with the help of 0.5mm styrene sheet material, so that the original stance could be kept. Lots of lead in the nose ensured that the model would properly stand on its three wheels.
Once the rhinoplasty was done I drilled four holes into the nose and used hollow steel needles as gun barrels, with a look reminiscent of the Douglas A-20G.
Adding the (perfectly) clear parts of the canopy as a final assembly step also turned out to be a major fight against the elements.
Painting and markings:
With an USAAF WWII prototype in mind, there were only two options: either an NMF machine, or a camouflage in Olive Drab and Neutral Grey. I went for the latter and used Tamiya XF-62 for the upper surfaces and Humbrol 156 (Dark Camouflage Grey) underneath. The kit received a light black ink wash and some post shading in order to emphasize panels. A little dry-brushing with silver around the leading edges and the cockpit was done, too.
The cockpit interior became chromate green (I used Humbrol 150, Forest Green) while the landing gear wells were painted with zinc chromate yellow (Humbrol 81). The landing gear itself was painted in aluminum (Humbrol 56).
Markings/decals became minimal, puzzled together from various sources – only some “Stars and Bars” insignia and the serial number.
Somehow this conversion ended up looking a lot like the contemporary Soviet Sukhoi Su-9 and -11 (Samolyet K and LK) jet fighter prototype – unintentionally, though. But I am happy with the outcome – the P-63 ancestry is there, and the Meteor engines are recognizable, too. But everything blends into each other well, the whole affair looks very balanced and believable. This is IMHO furthermore emphasized by the simple paint scheme. A jet-powered Kingcobra? Why not…?

Some background:
The Indian „Samudree Baaj“ (समुद्री बाज, Sea Hawk) was a highly modified, navalized version of the British BAE Systems Hawk land-based training jet aircraft, which had been manufactured under license by Hindustan Aeronautics Limited (HAL). The first indigenously built Hawk Mk. 132 trainer was delivered in 2008 to the Indian Air Force, and the type has since then been updated with indigenous avionics into the “Hawk-I” Mk. 132 from 2020 onwards. The aircraft’s Rolls Royce Adour Mk 871 engine was also license-built by HAL, and the company had experience from a wide range of aircraft projects in the past.
The Samudree Baaj project was initiated in 2006 by the Indian Navy, as part of the long historic plan to provide the Indian Navy with a fully capable aircraft carrier. This plan had been initiated in 1989, when India announced a plan to replace its ageing British-built aircraft carriers, INS Vikrant and INS Viraat (ex-HMS Hermes), with two new 28,000-ton Air Defence Ships (ADS) that would operate the BAe Sea Harrier aircraft. The first vessel was to replace Vikrant, which was set to decommission in early 1997. Construction of the ADS was to start at the Cochin Shipyard (CSL) in 1993 after the Indian Naval Design Organisation had translated this design study into a production model. Following the 1991 economic crisis, the plans for construction of the vessels were put on hold indefinitely.
In 1999, then-Defence Minister George Fernandes revived the project and sanctioned the construction of the Project “71 ADS”. By that time, given the ageing Sea Harrier fleet, the letter of intent called for a carrier that would carry more modern jet fighters. In 2001, CSL released a graphic illustration showing a 32,000-ton STOBAR (Short Take-Off But Arrested Recovery) design with a pronounced ski jump. The aircraft carrier project finally received formal government approval in January 2003. By then, design updates called for a 37,500-ton carrier to operate the MiG-29K. India opted for a three-carrier fleet consisting of one carrier battle group stationed on each seaboard, and a third carrier held in reserve, in order to continuously protect both its flanks, to protect economic interests and mercantile traffic, and to provide humanitarian platforms in times of disasters, since a carrier can provide a self-generating supply of fresh water, medical assistance or engineering expertise to populations in need for assistance.
In August 2006, then-Chief of the Naval Staff, Admiral Arun Prakash stated that the designation for the vessel had been changed from Air Defence Ship (ADS) to Indigenous Aircraft Carrier (IAC). The euphemistic ADS had been adopted in planning stages to ward off concerns about a naval build-up. Final revisions to the design increased the displacement of the carrier from 37,500 tons to over 40,000 tons. The length of the ship also increased from 252 metres (827 ft) to 262 metres (860 ft).
It was at this time that, beyond the MiG-29K, primarily a carrier-capable trainer and also a light (and less costly) strike aircraft would be needed. With the running production of the Hawk Mk. 132 for the Indian Air Force and BAE Systems’ connection and experience to the USA and McDonnell/Boeing’s adaptation of the Hawk as the US Navy’s carrier-capable T-45 trainer, HAL was instructed to develop a suitable aircraft family on the Hawk’s basis for the new carriers.
HAL’s Samudree Baaj is a fully carrier-capable version of the British Aerospace Hawk Mk. The Hawk had not originally been designed to perform carrier operations, so that numerous modifications were required, such as the extensive strengthening of the airframe to withstand the excessive forces imposed by the stresses involved in catapult launches and high sink-rate landings, both scenarios being routine in aircraft carrier operations.
The aerodynamic changes of the aircraft, which were mutually developed by HAL and BAE Systems, included improvements to the low-speed handling characteristics and a reduction in the approach speed. Most notable amongst the changes made to the Hawk's design were extended flaps for better low-speed handling, along with the addition of spoilers on the wings to reduce lift and strakes on the fuselage which improved airflow and stabilizer efficiency.
Other, less obvious modifications included a reinforced airframe, the adoption of a more robust and widened landing gear, complete with a catapult tow bar attachment to the oleo strut of the new two-wheel nose gear design, and an arresting hook. The tail fin was extended by 1 foot (12 in, 30.5 cm) to compensate for the loss of the Hawk’s ventral stabilizing strakes. To make room for the arrester hook, the original ventral air brake was split and re-located to the flanks, similar to the USN’s T-45 trainer.
At the time of the Samudree Baaj’s design, the exact catapult arrangement and capacity on board of India’s new carriers was not clear yet – even more so, since the MiG-29K and its powerful engines might have made a catapult obsolete. Therefore, the Samudree Baaj was designed to be operable either with a ski jump ramp (in the style of the Russian Kiev class carriers, of which India had purchased one as INS Vikramaditya) or with only minimal launch support within the projected STOBAR concept, which included a relatively short-stroke steam catapult and a similarly short, undampened arrester gear.
By 2009 the basic airframe had been defined and four prototypes were built for two versions: the Mk. 101 trainer, which was basically a navalized version of the land-based Mk. 132 with almost the same mission equipment, and the Mk. 201, a single-seater. Two airframes of each type were built and the first Samudree Baaj flight took place in early 2011. The Indian government ordered 30 trainers and 15 attack aircraft, to be delivered with the first new Indian carrier, INS Vikrant, in late 2017.
The Samudree Baaj Mk. 201 was developed from the basic navalized Hawk airframe as a light multirole fighter with a small visual signature and high maneuverability, but high combat efficiency and capable of both strike and point defense missions. It differed from the trainer through a completely new forward fuselage whereby the forward cockpit area, which normally housed the trainee, was replaced by an electronics bay for avionics and onboard systems, including a fire control computer, a LINS 300 ring laser gyroscope inertial navigation system and a lightweight (145 kg) multimode, coherent, pulse-Doppler I band airborne radar. This multimode radar was developed from the Ferranti Blue Fox radar and capable of airborne interception and air-to-surface strike roles over water and land, with look-down/shoot-down and look-up modes. It had ten air-to-surface and ten air-to-ground modes for navigation and weapon aiming purposes.
A ventral fairing behind the radome carried a laser rangefinder and a forward-looking infrared (FLIR). Mid-air refueling was also possible, through a detachable (but fixed) probe. GPS navigation or modern night-flight systems were integrated, too.
Like the trainer, the Mk. 201 had a total of seven weapon hardpoints (1 ventral, four underwing and a pair of wing tip launch rails), but the more sophisticated avionics suite allowed a wider range of ordnance to be carried and deployed, which included radar-guided AAMs for BVR strokes and smart weapons and guided missiles – especially the Sea Eagle and AGM-84 “Harpoon” anti-ship missiles in the Indian Navy’s arsenal. For the maritime strike role and as a support for ASW missions, the Samudree Baaj Mk. 201 could even deploy Sting Ray homing torpedoes.
Furthermore, a pair of 30mm (1.18 in) ADEN machine cannon with 150 RPG were housed in a shallow fairing under the cockpit. The self-protection systems include a BAE SkyGuardian 200 RWR and automatic Vinten chaff/flare dispensers located above the engine exhaust.
The Samudree Baaj project was highly ambitious, so that it does not wonder that there were many delays and teething troubles. Beyond the complex avionics integration this included the maritime adaptation of the Adour engine, which eventually led to the uprated Adour Mk. 871-1N, which, as a side benefit, also offered about 10% more power.
However, in parallel, INS Vikrant also ran into delays: In July 2012, The Times of India reported that construction of Vikrant has been delayed by three years, and the ship would be ready for commissioning by 2018. Later, in November 2012, Indian English-language news channel NDTV reported that cost of the aircraft carrier had increased, and the delivery has been delayed by at least five years and is expected to be with the Indian Navy only after 2018 as against the scheduled date of delivery of 2014. Work then commenced for the next stage of construction, which included the installation of the integrated propulsion system, the superstructure, the upper decks, the cabling, sensors and weapons. Vikrant was eventually undocked on 10 June 2015 after the completion of structural work. Cabling, piping, heat and ventilation works were to be completed by 2017; sea trials would begin thereafter. In December 2019, it was reported that the engines on board the ship were switched on and in November 2020, only the basin trials of the aircraft carrier were completed.
By that time, the first Samudree Baaj aircraft had been delivered to Indian Navy 300 squadron, and even though only based at land at Hansa Air Station, flight training and military operations commenced. In the meantime, the start of Vikrant's trials had initially been scheduled to begin on 12 March 2020, but further construction delays caused that to be moved back to April. With the COVID-19 crisis, the navy explained that trials were unlikely to begin before September/October. During the Navy Day press meeting in December 2019, Navy Chief Admiral Karambir Singh said Vikrant would be fully operational before the end of 2022. The COVID-19 pandemic had already pushed that back to 2023 and further delays appeared possible.
In late 2020, the Indian Navy expected to commission Vikrant by the end of 2021. Until then, the Samudree Baaj fleet will remain land-based at INS Hansa near Goa. This not only is the INAS 300 home base, it is also the location of the Indian Navy's Shore Based Test Facility (SBTF), which is a mock-up of the 283-metre (928 ft) INS Vikramaditya (a modified Kiev-class aircraft carrier) deck built to train and certify navy pilots, primarily the the Mikoyan MiG-29K for operating from the aircraft carrier, but now also for the Samudree Baaj and for the developmental trials of the naval HAL Tejas lightweight fighter.

The kit and its assembly:
A subtle kitbashing project, inspired by a CG-rendition of a carrier-based (yet un-navalized) BAe Hawk 200 in Indian Navy service by fellow user SPINNERS in January 2021. I found the idea inspiring but thought that the basic concept could be taken further and into hardware form with a model. And I had a Matchbox Hawk 200 in The Stash™, as well as a McDonnell T-45 trainer from Italeri…
The plan sounds simple: take a T-45 and replace the cockpit section with the single-seat cockpit from the Hawk 200. And while the necessary cuts were easy to make, reality rears its ugly head when you try to mate parts from basically the same aircraft but from models by different manufacturers.
The challenges started with the fact that the fuselage shapes of both models differ – the Matchbox kit is more “voluminous”, and the different canopy shape called for a partial spine transplant, which turned out to be of very different shape than the T-45’s respective section! Lots of PSR…
In order to improve the pretty basic Matchbox Hawk cockpit I integrated the cockpit tub from the Italeri T-45, including the ejection seat, dashboard and its top cover.
For the totally different T-45 front wheel I had to enlarge the respective well and added a “ceiling” to it, since the strut had to be attached somewhere. The Hawk 200’s ventral tub for the cannons (which only the first prototype carried, later production aircraft did not feature them) were retained – partly because of their “whiffy“ nature, but also because making it disappear would have involved more major surgeries.
Most of the are behind the cockpit comes from the Italeri T-45, I just added a RHAWS fairing to the fin, extending it by 3mm.
A major problem became the air intakes, because the two kits differ in their construction. I wanted to use the Italeri parts, because they match the fairings on the fuselage flanks well and are better detailed than the Matchbox parts. But the boundary layer spacers between intakes and fuselage are molded into the Italeri parts, while the Matchbox kit has them molded into the fuselage. This called for major surgery and eventually worked out fine, and more PSR blended the rest of the fuselage donors around the cockpit together. A tedious process, though.
The pylons were puzzled together, including a former Matchbox EA-6B wing pylon under the fuselage, cut down and mounted in reverse and upside down! The ordnance comes from the Italeri NATO weapons set (Matra Magic and AGM-84), the ventral drop tank comes IIRC from an Eduard L-39 Albatros. Matra Magics were chosen because India never operated any Sidewinder AAM, just French or Soviet/Russian missiles like the R-60 or R-73 (unlikely on the Hawk, IMHO), and I had preferred a pair of Sea Eagle ASMs (from a Hasegawa Sea Harrier kit), but their span turned out to be too large for the Hawk’s low wings. The alternative, more slender Harpoons are plausible, though, since they are actually part of the Indian Navy’s inventory.
Painting and markings:
The Indian Navy theme was already settled, and I wanted to stay close to SPINNERS’ illustration as well as to real world Indian Navy aircraft. SPINNERS’ Hawk carried the typical Sea Harreir scheme in Extra Dark Sea Grey and White, and I found this livery to look a bit too much retro, because I’d place this what-if aircraft in the early 2020s, when the Sea Harriers had already been phased out. A “realistic” livery might have been an overall mid-grey paint scheme (like the land-based Indian Hawk 132s), but I found this to look too boring. As a compromise, I gave the Samudree Baaj a simple two-tone paint scheme, carried by a few late Indian Sea Harriers. It consists of upper surfaces in Dark Sea Grey (Humbrol 164) and undersides in Medium Sea Grey (Modelmaster 2058), with a low waterline. The Modelmaster MSG has – for my taste – a rather bluish hue and appears almost like PRU Blue, but I left it that way.
The decals were puzzled together from variosu sources. the roundels come from a MiG-21F (Begemot), the unit markings and tactical codes from a Model Alliance Sea Harrier sheet, and the stencils are a mix from the Matchbox Hawk 200 and the Italeri T-45.
The kit was sealed with matt acrylic varnish from Italeri.
The fictional HAL „Samudree Baaj“ looks simple, but combining kits of the basically same aircraft from different manufacturers reveals their differences, and they are not to be underestimated! However, I like the result of a navalized Hawk single-seater, and - also with the relatively simple and dull livery - it looks pretty convincing.
Many thanks to SPINNERS for the creative inspiration - even though my build is not a 100% "copy" of the artwork, but rather a step further into the navalisation idea with the T-45 parts.
Some background:
The Leyland “Type D” was one of several armoured vehicle types designed in 1940 on the orders of Lord Beaverbrook and Admiral Sir Edward Evans, as a part of the hasty measures taken by the British Government following the Dunkirk evacuation and the threat of invasion.
The “Type D” was a heavy scout car, intended to replace the Lanchester 6x4 and Rolls-Royce 4x2 armoured cars, which dated back to the WWI era and the early interwar period. While they were reliable vehicles and still in active service, their off-road capabilities, armament and armour left a lot to be desired – esp. in the face of the modern German army and its effective equipment.
Certainly inspired by the German SdKfz. 231/232 family of heavy 8x8 armoured reconnaissance vehicles, Leyland added a fourth axle to better distribute the vehicle’s weight and a drivetrain to the front axle to a modified “Retriever” 3-ton 6x4 lorry chassis, resulting in a 6x8 layout. The rigid axles were mounted on leaf springs front and rear with hydraulic dampers, both front axles were steerable. The engine, a water-cooled 6-litre, 4-cylinder overhead camshaft petrol engine with 73 hp, was, together with the gearbox, relocated to the rear, making room for a fully enclosed crew compartment in the front section with two access doors in the vehicle’s flanks. The crew consisted of four, with the driver seat at the front. The gunner and commander (the commander at the right and gunner at the left) stood behind them into the turret or were sitting on simple leather belts, and behind them was a working station for a radio operator.
The tall, cylindrical turret was welded and electrically traversed, but it lacked a commander cupola. All the armament was mounted in the turret and consisted of a quick-firing two-pounder (40mm) cannon and a coaxial 7.92 mm Besa machine gun. The faceted hull was, like the turret, welded from homogenous steel armour plates, and a straightforward design. Maximum armour thickness was 15 mm at the front, 8 mm on the sides, and 10 mm on the back, with 6 mm and 5 mm of armour on the top and bottom respectively. It had been designed to provide protection from small arms fire and HE fragments, but it was ineffective against heavier weapons. This armour was a compromise, since better protection had resulted in a higher weight and overstrained the Type D’s lorry chassis and engine. The armoured cabin was mounted to the chassis at only four points - front, rear and sides - to give some flexibility but with precautions against excessive movement.
The Type D’s prototype was designed, built, tested and approved just within 3 months. Deliveries of the first production vehicles commenced only 2 months later, just in time to become involved in the North Africa campaign. All early production vehicles were immediately sent to Egypt and took part in Operation Compass and the Western Desert Campaign.
It comes as no surprise that the Type D – developed and produced in a hurry and thrown into battle in an environment it had not been designed for – initially failed, and even when the worst deficits had been rectified the Type D’s performance remained mediocre at best. The biggest problems concerned the engine’s cooling system, its low power output and therefore poor speed, and the vehicle’s poor off-road performance, esp. on soft ground like sand. The vehicle’s suspension was quickly overburdened in heavy terrain and the tall turret placed its center of gravity very high, making the Type D prone to topple over to a side when slope angles were taken too slightly. Poor cabin ventilation was another problem that became even more apparent under the African sun.
Initial losses were high: more than half of the Type Ds lost in North Africa during the early months of 1941 were abandoned vehicles which got stuck or had to be left behind due to mechanical failures. The rest had fallen easy prey to German and Italian attacks – the Type D was not only very vulnerable even to the Panzer II’s 20 mm autocannon, its thin top armour made it in the open desert also very vulnerable to air attacks: German MG 131 machine gun rounds easily punched the vehicle’s shell, and even lighter weapons were a serious threat to the tall Type D.
As soon as the first sobering field reports returned back to Great Britain, Leyland immediately devised major improvements. These were introduced to newly produced Mk. II vehicles and partly retrofitted to the early Mk. I vehicles in field workshops. One of these general improvements were new desert wheels and tires, which were considerably wider than the original lorry wheels and featured a flat pattern that better distributed the vehicle’s weight on soft and unstable ground, what considerably improved the Type D’s performance on sand. A kit with a more effective radiator and a bigger engine cooling system was quickly developed and sent to the units in Africa, too. The kit did not fully solve the overheating problems of the early Mk. I, but improved the situation. From the outside, retrofitted Type Ds could be recognized by a raised engine cover with enlarged air intakes. Due to the limits of the chassis the armour level was not improved, even though the crews and field workshops tried to attach improvised additional protective measures like spare track links from tanks or sandbags – with mixed results, though. The armament was not updated either, except for an optional mount for an additional light anti-aircraft machine gun on the turret and kits for smoke dischargers on the turret’s flanks.
The Type D Mk. II, which gradually replaced the Mk. I on the production lines from March 1941 on, furthermore received a different and much more effective powerplant, a Leyland 7-litre six-cylinder diesel engine with an output of 95 hp (70 kW). It not only provided more power and torque, markedly improving the vehicle’s off-road performance, it also had a better fuel economy than the former lorry petrol engine (extending range by 25%), and the fuel itself was less prone to ignite upon hits or accidents.
During its short career the Leyland Type D was primarily used in the North African Campaign by the 11th Hussars and other units. After the invasion of Italy, a small number was also used in the Southern European theatre by reconnaissance regiments of British and Canadian infantry divisions. A few vehicles were furthermore used for patrol duty along the Iran supply route.
However, the Type D was not popular, quickly replaced by smaller and more agile vehicles like the Humber scout car, and by 1944 outdated and retired. Leyland built a total of 220 Type Ds of both versions until early 1943, whilst an additional 86 Mk. IIs were built by the London, Midland and Scottish Railway's Derby Carriage Works.

The kit and its assembly:
This fictional British WWII vehicle might look weird, but it has a real-world inspiration: the Marmon Herrington Mk. VI armoured heavy scout car. This vehicle only existed as a prototype and is AFAIK still preserved in a museum in South Africa – and upon a cursory glance it looks like an SdKfz. 232 with the shrunk turret from a “Crusader” cruiser tank with a short-barreled six pounder gun. It looks like a fake! Another reason for this build was a credible “canvas” for the application of the iconic “Caunter Scheme”, so that I placed the Type D in a suitable historic time frame.
The Type D was not supposed to be a truthful Marmon Herrington Mk. VI copy, so I started with a 1:72 “First to Fight” SdKfz. 232. This is a simple and sturdy tabletop wargaming model, but it is quite accurate, goes together well, is cheap and even comes with a metal gun barrel. It’s good value for the money, even though the plastic is a little thick and soft.
However, from this basis things changed in many ways. I initially wanted to shorten the hull, but the new wheels (see below) made this idea impossible. Nevertheless, the front glacis plate was completely re-modeled with 2C putty in the style of the Humber scout car, and the crew cabin was extended backwards with the same method. New observation slits had to be scratched with styrene profile material. The engine bay received a raised cover, simulating extra air intakes. The turret was replaced with a resin piece for an A13 “Valentine” Mk.III tank (S&S Models), which had a perfect size and even came with a suitable gun.
The suspension was taken OOB, but the wheels were replaced with two aftermarket resin sets (Silesian Models) with special Allied desert wheels/tires from 1941, they originally belong to a Chevrolet truck and are markedly bigger and wider than the SdKfz. 232 wheels. However, they had to be modified to match the rest of the suspension, and their size necessitated a thorough modification of the mudguards. They were not only mounted 1mm higher on the flanks, their sides, normally consisting of closed skirts, were fully opened to make sufficient room for the new wheels to change the vehicle’s look. They were furthermore separated into four two-wheel covers and their front and rear ends were slightly bent upwards. Sufficient space for the side doors had to be made, too. The spare wheels that came with the respective sets were mounted to the front (again Humber-style) and onto the engine bay cover, under a scratched tarpaulin (made from paper tissue drenched with white glue).
To conceal the SdKfz. 232 heritage even more I added more equipment to the vehicle’s flanks. Tool boxed were added to the engine bay’s flanks, some more tools to the fenders, scratched tarpaulin rolls above the side doors and I tried to scratch PSP plates with aluminum foil rubbed against a flight stand diorama floor made from PSP. Not perfect, but all the stuff livens the Type D up. A new exhaust (IIRC from a Panzer IV) was added to the rear and bumpers scratched from wire and mounted low unto the hull.
Painting and markings:
Finally, the British, so-called “Caunter Scheme”, a great source of misinterpretation not only in museums but also by modelers who have painted their British tanks in dubious if not garish colors. I do not claim that my interpretation of the colors is authentic, but I did some legwork and tried to improvise with my resources some tones that appear plausible (at least to me), based on descriptions and contemporary references.
The pattern itself was well defined for each vehicle type, and I adapted a M3 “Stuart” pattern for the model. All three basic colors, “Light Stone”, “Silver Grey” and “Slate”, were guesstimated. “Slate” is a relatively dark and greenish tone, and I chose Tamiya XF-65 (Field Grey). “Light Stone” is rather yellow-ish, light sand tone, and I used Humbrol 103 (Cream). Some sources suggest the use of Humbrol 74 (linen) as basis, but that is IMHO too yellow-ish and lacks red. The most obscure tone is “Silver Grey”, and its depictions range from a pale and dull light olive drab over blue-grey, greenish grey to bright light blue and even turquoise. In fact, this tone must have had a greenish-blue hue, and so I mixed Humbrol 145 (FS 35237) with maybe Humbrol 94 in a 3:1 ratio to achieve an “in between” tone, which is hard to describe - maybe as a greenish sand-grey? A funny effect of the colors in direct contrast is that the XF-65 appeared with an almost bluish hue! Overall, the choice of colors seems to work, though, and the impression is good.
Painting was, as usual, done with brushes and, due to the vehicle’s craggy shape, free-handedly. After basic painting the model received a light washing with a mix of black ink and brown, and some post-shading was done with light grey (Revell 75) and Hemp (Humbrol 168). Decals came from the scrap box, and before an overall protective coat of matt acrylic varnish was applied, the model received an additional treatment with thinned Revell 82 (supposed to be RAF Dark Earth but it is a much paler tone).
A more demanding build than one would expect at first sight. The SdKafz. 232 is unfortunately still visible, but the desert wheels, including the spare wheels, change the look considerably, and the British replacement turret works well, too. Using the tabletop model basis was not a good move, though, because everything is rather solid and somewhat blurry, esp. the many molded surface details, which suffered under the massive body work. On the other side, the Counter Scheme IMHO turned out well, esp. the colors, even though the slender hull made the adaptation of the pattern from a (much shorter) tank not easy. But most of the critical areas were hidden under extra equipment, anyway. 😉

Some background:
The Soviet Laboratory of High-Speed Automobiles (LSA ChADI, today the Chardiv National Automobile and Highway University) was founded in 1953. One of the laboratory’s founders was Vladimir Nikitin, a famous racer not only inside the Soviet Union but also around the world. The main purpose of Vladimir Nikitin’s of was to build the fastest car in the world. This idea of creating race cars became the purpose of the laboratory and has been continued by students of Nikitin throughout the years, with research and prototypes in various fields of car propulsion.
The first car created in LSA by students was ChADI 2 in 1961. The body of the car was made of fiberglass, the first time that this material was used for a car body in the Soviet Union. This technology was improved and later used in mass-produced cars. Another famous LSA car was ChADI 7. To create it, Nikitin and his students used airplane wing elements as car body material and used the engine from a helicopter to power it. The highest speed of ChADI 7 – 400 kilometers per hour – was recorded on an airport runway near Chardiv in 1968, and it was at that time the fastest car in the Soviet Union, setting the national land speed record.
After this successful vehicle, Vladimir Nikitin started a new, even more ambitious project: a speed record car with the jet engine from a high performance airplane! The name of this project was ChADI 9, and it was ambitious. This time Nikitin and his team used a Tumansky RD-9 turbojet engine with a dry thrust of 25.5 kN (5,730 lbf), the same engine that powered the supersonic Mikoyan-Gurewich MiG-19 fighter plane. He expected that this needle-shaped car would be able to break the absolute land speed record, which meant supersonic speed at level zero of almost 1.200 kilometers an hour. The car was finished in 1981, but unfortunately ChADI 9 never participated in any race and no official top speed result was ever recorded. This had initially a very practical reason: in the 1980’s there were simply no tires in the USSR that could be safely used at the expected speeds in excess of 400 km/h, and there was furthermore no track long enough for a serious test drive in the Soviet Union! In consequence, ChADI 9 had to be tested on the runway of a military airport in the proximity of Chardiv, outfitted with wheels and tires from a MiG-19, but these were not ideal for prolonged high speeds. Film footage from these tests later appeared in a 1983 movie called “IgLa”.
The Automotive Federation of the United States even invited ChADI 9 to participate in an official record race in the USA, but this did not happen either, this time for political reasons. Nevertheless, the main contribution of this car was gathering experience with powerful jet engines and their operations in a ground vehicle, as well as experience with car systems that could withstand and operate at the expected high levels of speed, and the vehicle was frequently tested until it was destroyed in high speed tests in 1988 (see below).
ChADI 9 was not the end of Nikitin’s strife for speed (and the prestige associated with it). The know-how that the design team had gathered in the first years of testing ChADI 9 were subsequentially integrated into the LSA’s ultimate proposal not only to break the national, but also the absolute land speed record: with a new vehicle dubbed ChADI 9-II. This car was a completely new design, and its name was deliberately chosen in order to secure project budgets – it was easier to gain support for existing (and so far successful) projects rather than found new ones and convince superior powers of their value and success potential.
ChADI 9-II’s conceptual phase was launched in 1982 and it was basically a scaled-up evolution of ChADI 9, but it featured some significant differences. Instead of the RD-9 turbojet, the new vehicle was powered by a much more potent Tumansky R-25-300 afterburning turbojet with a dry thrust of 40.21 kN (9,040 lbf) and 69.62 kN (15,650 lbf) with full afterburner. This new engine (used and proven in the MiG-21 Mach 2 fighter) had already been thoroughly bench-tested by the Soviet Laboratory of High-Speed Automobiles in 1978, on an unmanned, tracked sled.
However, the development of ChADI 9-II and its details took more than two years of dedicated work by LSA ChADI’s students, and in 1984 the design was finally settled. The new vehicle was much bigger than its predecessor, 44 ft 10 in long, 15 ft 6¾ in wide, and 9 ft 10¾ in high (13.67 m by 4,75 m by 3,02 m), and it weighed around 9,000 lb (4 t). Its construction was based on a steel tube frame with an integrated security cell for the driver and an aluminum skin body, with some fibre glass elements. While ChADI 9’s slender cigar-shaped body with a circular diameter and the tricycle layout were basically retained, the front end of ChADI 9-II and its internal structure were totally different: instead of ChADI 9’s pointed nose, with the cockpit in the front and ahead of the vehicle’s front wheel and a pair of conformal (but not very efficient) side air intakes, ChADI 9-II featured a large, single orifice with a central shock cone. A small raked lower lip was to prevent FOD to the engine and act at the same time as a stabilizing front spoiler. The driver sat under a tight, streamlined canopy, the bifurcated air intake ducts internally flanking the narrow cockpit. Two steerable front wheels with a very narrow track were installed in front of the driver’s compartment. They were mounted side by side on a central steering pylon, which made them look like a single wheel. Behind the cockpit, still flanked by the air ducts, came two fuel tanks and finally, after a chamber where the air ducts met again, the engine compartment. Small horizontal stabilizers under the cockpit, which could be adjusted with the help of an electric actuator, helped keeping the vehicle’s nose section on the ground. Two small air brakes were mounted on the rear fuselage; these not only helped to reduce the vehicle’s speed, they could also be deployed in order to trim the aerodynamic downforce on the rear wheels. The latter ware carried on outriggers for a wide and stable track width and were covered in tight aerodynamic fairings, again made from fibre glass. The outriggers were furthermore swept back far enough so that the engine’s nozzle was placed in front of the rear wheel axis. This, together with a marked “nose-down” stance as well as a single swept fin on the rear above the afterburner nozzle with a brake parachute compartment, was to ensure stability and proper handling at expected speeds far in excess of 600 km/h (372 mph) without the use of the engine’s afterburner, and far more at full power.
Construction of ChADI 9-II lasted for more than another year, and in May 1986 the vehicle was rolled out and ready for initial trials at Chardiv, this time on the Chardiv State Aircraft Manufacturing Company’s runway. These non-public tests were successful and confirmed the soundness of the vehicle’s concept and layout. In the course of thorough tests until July 1987, ChADI 9-II was carefully pushed beyond the 400 km/h barrier and showed certain potential for more. This was the point when the vehicle was presented to the public (it could not be hidden due to the noisy trials within Chardiv’s city limits), and for this occasion (and marketing purposes) ChADI 9-II received a flashy livery in silver with red trim around the air intake and long the flanks and was officially christened with the more catchy title “„скорость“” (Skorost = Velocity).
Meanwhile, a potential area for serious high-speed trials had been identified with Lake Baskunchak, a salt sea near the Caspian Sea with flat banks that resembled the Bonneville Salt Flats in the USA. Lake Baskunchak became the site of further tests in 1988. Initially scheduled for May-July, the tests had to be postponed by six weeks due to heavy rain in the region, so that the sea would not build suitable dry salt banks for any safe driving tests. In late June the situation improved, and „скорость“ could finally take up its high speed tests.
During the following weeks the vehicle was gradually taken to ever higher speeds. During a test run on 8th of September, while travelling at roundabout 640 km/h (400 mph), one of the tail wheel fairings appeared to explode and the ensuing drag differences caused heavy oscillations that ended in a crash at 180 km/h (110 mph) with the vehicle rolling over and ripping the left rear wheel suspension apart.
The driver, LSA student and hobby rally driver Victor Barchenkov, miraculously left the vehicle almost unscathed, and the damage turned out to be only superficial. What had happened was an air pressure congestion inside of the wheel fairing, and the increasing revolutions of the wheels beyond 600 km/h caused small shock waves along the wheels, which eventually blew up the fairing, together with the tire. This accident stopped the 1988 trials, but not the work on the vehicle. Another disaster struck the LSA ChADI team when ChADI 9, which was still operated, crashed in 1988, too, and had to be written off completely.
In mid-1989 and with only a single high speed vehicle left, LSA team appeared again with „скорость“ at the shores of Lake Baskunchak – and this time the weather was more gracious and the track could be used from late June onwards. Analyzing last year’s accident and the gathered data, the vehicle had undergone repairs and some major modifications, including a new, anti-corrosive paintjob in light grey with red and white trim.
The most obvious change, though, was a completely re-shaped nose section: the original raked lower air intake lip had been considerably extended by almost 5 feet (the vehicle now had a total length of 49 ft 1 in/14,98 m) in order to enhance the downforce on the front wheels, and strakes along the lower nose ducted the airflow around the front wheels and towards the stabilizing fins. The central shock cone had been elongated and re-contoured, too, improving the airflow at high speeds.
New tireless all-aluminum wheels had been developed and mounted, because pressurized rubber tires, as formerly used, had turned out to be too unstable and unsafe. The central front wheels had received an additional aerodynamic fairing that prevented air ingestion into the lower fuselage, so that steering at high speeds became safer. The aerodynamic rear wheel fairings had by now been completely deleted and spoilers had been added to the rear suspension in order to keep the rear wheel on the ground at high speeds.
This time the goal was to push „скорость“ and the national land speed record in excess of 800 km/h (500 mph), and step by step the vehicle’s top speed was gradually increased. On August 15, an officially timed record attempt was made, again with Victor Barchenkov at the steering wheel. The first of the two obligatory runs within an hour was recorded at a very promising 846.961 km/h (526.277 mph), but, at the end of the second run, „скорость“ veered off and no time was measured. Even worse, the vehicle lost its parachute brakes and went out of control, skidding away from the dry race track into Lake Baskunchak’s wet salt sludge, where it hit a ground wave at around 200 mph (320 km/h) and was catapulted through the air into a brine pond where it landed on its right side and eventually sank. Again, pilot Victor Barchenkov remained mostly unharmed and was able to leave the car before it sank – but this fatal crash meant the end of the „скорость“ vehicle and the complete KhAGI 9-II project. Furthermore, the break-up of the Soviet Union at the same time prevented and further developments of high speed vehicles. The whereabouts of the „скорость“ wreck remain unclear, too, since no official attempt had been made to save the vehicle’s remains from Lake Baskunchak’s salt swamps.
The kit and its assembly:
This is another contribution to the late 2018 “Racing & Competition Group Build” at whatifmodelers.com. Since I primarily build aircraft in 1:72 scale, building a land speed record (LSR) vehicle from such a basis appeared like a natural choice. A slick streamliner? A rocket-powered prototype with Mach 1 potential? Hmmm… However, I wanted something else than the typical US or British Bonneville Salt Flats contender.
Inspiration struck when I remembered the real world high speed vehicle projects of LSA ChAGI in the former USSR, and especially the ill-fated, jet-powered ChADI 9, which looked a lot like Western, rocket-powered absolute LSR designs like The Blue Flame or Wingfoot Express 2. Another inspiration was a contemporary LSR vehicle called North American Eagle – basically a wingless F-104 Starfighter, put on wheels and sporting a garish, patriotic livery.
With this conceptual basis, the MiG-21 was quickly identified as the potential starting basis – but I wanted more than just a Fishbed sans wings and with some bigger wheels attached to it. I nevertheless wanted to retain the basic shape of the aircraft, but change the rest as good as possible with details that I have learned from reading about historic LSR vehicles (a very good source are the books by German author and LSR enthusiast Ferdinand C. W. Käsmann, which have, AFAIK, even been translated into English).
At the model’s core is a contemporary KP MiG-21MF, but it’s a hideous incarnation of the venerable Kovozávody Prostějov mold. While the wheels and the dashboard of this kit were surprisingly crisp, the fuselage halves did hardly match each other and some other parts like the landing gear covers could only be described as “blurred blobs”. Therefore it was no shame to slice the kit up, and the resulting kitbash with many donor parts and scratching almost became a necessity.
The MiG-21 fuselage and cockpit were more or less retained, the landing gear wells covered and PSR-ed. Fin, spine and the ventral stabilizer were cut away, and the attachment points for the wings and the horizontal stabilizers blended into the rest of the fuselage. Actually, only a few parts from the KP MiG-21 were eventually used.
The original shock cone in the air intake was used, but it was set further back into the nose opening – as an attachment point for a new, more organic shock cone which is actually the rear end of a drop tank from an Airfix 1:72 P-61 Black Widow. This detail was inspired by a real world benchmark: Art Arfons’ home-built “Green Monster” LSR car. This vehicle also inspired the highly modified air intake shape, which was scratched from the tail cone from a Matchbox 1:72 Blackburn Buccaneer – the diameter matched well with the MiG-21’s nose! With the new nose, I was able to retain the original MiG-21 layout, yet the shape and the extension forward changed the overall look enough to make it clear that this was not simply a MiG-21 on wheels.
With the spine gone, I also had to integrate a different, much smaller canopy, which came from an 1:144 Tornado. The cockpit opening had to be narrowed accordingly, and behind the canopy a new spine fairing was integrated – simply a piece from a streamlined 1:72 1.000 lb bomb plus lots of PSR.
Inside of the cockpit, a simpler seat was used, but the original cockpit tub and the dashboard were retained.
The large MiG-21 fin was replaced with a smaller piece, left over from an Amodel Kh-20 missile, with a scratched brake parachute fairing (cut from sprue material) placed under its rear. The exhaust nozzle was replaced, too, because the fit of the KP MiG-21’s rear end was abysmal. So I cut away a short piece and added an afterburner nozzle from a vintage 1:72 F-100, which fits well. Inside, the part’s rear wall was drilled open and extended inwards with a styrene tube.
The wheels of the vehicle come from an 1:72 Hasegawa “Panther with Schmalturm” tank kit – it comes not only with two turrets, but also with a second set of simplified track wheels. These had IMHO the perfect size and shape as massive aluminum wheels for the high speed vehicle.
For the front wheels, I used the thinner outer Panther wheels, and they were put, closely together, onto a central suspension pylon. This received a new “well” in the forward fuselage, with an internal attachment point. In order to streamline the front wheel installation (and also to change the overall look of the vehicle away from the MiG-21 basis), I added a scratched an aerodynamic fairing around it. This was made from tailored styrene strips, which were later filled and blended into the hull with putty.
The rear suspension was also fully scratched: the outriggers were made from styrene profiles while the wheel attachments were once part of an 1:35 tank kit suspension – I needed something to hold the three struts per side together. These parts look a bit large, but the vehicle is, after all, a Soviet design, so a little sturdiness may not be wrong, and I simply did not want to stick the wheels directly onto the outriggers. The rear wheels (in this case, the wider inner Panther track wheels with a central hub cover were used) also received a stabilizing notch around the contact surface, in an attempt to make them look slimmer than they actually are.
Final touches included the chines under the nose as well as spoilers on the rear suspension (both made from styrene profiles), and I added a pitot made from wire to the original MiG-21 angle of attack sensor fairing.
As an addition outside the model itself I also created a display base for the beauty pics, since I did not have anything at hand that would resemble the vastness of a flat and dry salt sea. The base is an 18x12” MDF board, on top of which I added a thin coat of white tile grout (which I normally use as a snow placebo, instead of plaster, which tends to absorb humidity over time and to become yellow). While the stuff was still wet I sprinkled some real salt onto the surface and wetted the whole affair with water sprays – hoping to create a flat yet structured surface with some glitter reflexes. And it actually worked!
Painting and markings:
I am not certain how ChADI 9 was painted (I assume overall silver), but I wanted for „скорость“ a little more color. Being a child of the Soviet era, red was a settled design element, but I thought that an all-red vehicle might have looked too cheesy. Other colors I considered were orange or white with blue trim, but did not find them to be appropriate for what I was looking. Eventually, I added some Russian Utilitarianism in the form of light grey for the upper hull (Humbrol 166, RAF Light Aircraft Grey), and the red (Humbrol 19) as a dark contrast around the complete air intake as well as the shock cone (somewhat inspired by the Green Monster #15 LSR vehicle), and then extended backwards into a narrowing cheatline along the flanks, which emphasizes the vehicle’s slender hull. For some more contrast between the two basic tones I later added thin white borders between them created with 2mm white decal stripes from TL Modellbau. Around the hull some bright red (Humbrol 238 Red Arrows Red) highlights as warning signs were added.
The vehicle’s afterburner section was painted with Modelmaster Steel Metallizer, the Panther wheels became Aluminum (Revell 99) with a black ink wash. Some black ink was also applied to the jet nozzle, so that the details became more pronounced, and some grinded graphite was used to enhance the burnt metal effect.
Since this would rather be an experimental car built and operated by a high school institute, and also operated in the Soviet Union, flashy sponsor markings would not be appropriate. Therefore I created some fictional marking at home with the help of PC software and printed them by myself. These designs included a fictional logo of the ChADI institute itself (created from a car silhouette drawing) and a logo for the vehicle’s title, “„скорость““. The latter was created from the cyrillic lettering, with some additions like the vehicle’s silhouette.
Unfortunately the production process for the home-made decals did not work properly – when coating the prints with gloss acrylic varnish the printer ink started to dissolve, bleeding magenta, so that the decals would look as if there was a red halo or glow around the otherwise black motifs. Thanks to the use of red in the vehicle’s overall design this flaw is not too apparent, so I stuck with the outcome and applied the decals to the car.
Beyond these basic markings, many stencils were added, including dull red inscriptions from an Italeri MiG-37 “Ferret” kit – finally, I found an expedient use for them! The Soviet flags on the fin came from an 1:144 Tu-144 airliner Braz Decal aftermarket sheet.
Finally, some panel lines were drawn onto the hull with a soft pencil and then the model was sealed with Italeri semi-gloss acrylic varnish. Just the black anti-glare panel in front of the windscreen became matt and the metallic rear section was left in “natural” finish.
I am very pleased with the outcome – the „скорость“ looks purposeful and does IMHO blend well into the line of spectacular USA and UK jet/rocket car designs that broke the 800 km/h barrier. I also find that, even though the MiG-21 ancestry is certainly there, the vehicle looks different enough so that the illusion that it was designed along the jet fighter’s lines (and not converted from one, like the real world “North American Eagle” which was built from an F-104 Starfighter) works well. I also think that the vehicle’s livery works well – it looks quite retro for a vehicle from the late Eighties, but that just adds to the “Soviet style”. An interesting project, outside of my normal comfort zone. :D

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Soviet Laboratory of High-Speed Automobiles (LSA ChADI, today the Chardiv National Automobile and Highway University) was founded in 1953. One of the laboratory’s founders was Vladimir Nikitin, a famous racer not only inside the Soviet Union but also around the world. The main purpose of Vladimir Nikitin’s of was to build the fastest car in the world. This idea of creating race cars became the purpose of the laboratory and has been continued by students of Nikitin throughout the years, with research and prototypes in various fields of car propulsion.
The first car created in LSA by students was ChADI 2 in 1961. The body of the car was made of fiberglass, the first time that this material was used for a car body in the Soviet Union. This technology was improved and later used in mass-produced cars. Another famous LSA car was ChADI 7. To create it, Nikitin and his students used airplane wing elements as car body material and used the engine from a helicopter to power it. The highest speed of ChADI 7 – 400 kilometers per hour – was recorded on an airport runway near Chardiv in 1968, and it was at that time the fastest car in the Soviet Union, setting the national land speed record.
After this successful vehicle, Vladimir Nikitin started a new, even more ambitious project: a speed record car with the jet engine from a high performance airplane! The name of this project was ChADI 9, and it was ambitious. This time Nikitin and his team used a Tumansky RD-9 turbojet engine with a dry thrust of 25.5 kN (5,730 lbf), the same engine that powered the supersonic Mikoyan-Gurewich MiG-19 fighter plane. He expected that this needle-shaped car would be able to break the absolute land speed record, which meant supersonic speed at level zero of almost 1.200 kilometers an hour. The car was finished in 1981, but unfortunately ChADI 9 never participated in any race and no official top speed result was ever recorded. This had initially a very practical reason: in the 1980’s there were simply no tires in the USSR that could be safely used at the expected speeds in excess of 400 km/h, and there was furthermore no track long enough for a serious test drive in the Soviet Union! In consequence, ChADI 9 had to be tested on the runway of a military airport in the proximity of Chardiv, outfitted with wheels and tires from a MiG-19, but these were not ideal for prolonged high speeds. Film footage from these tests later appeared in a 1983 movie called “IgLa”.
The Automotive Federation of the United States even invited ChADI 9 to participate in an official record race in the USA, but this did not happen either, this time for political reasons. Nevertheless, the main contribution of this car was gathering experience with powerful jet engines and their operations in a ground vehicle, as well as experience with car systems that could withstand and operate at the expected high levels of speed, and the vehicle was frequently tested until it was destroyed in high speed tests in 1988 (see below).
ChADI 9 was not the end of Nikitin’s strife for speed (and the prestige associated with it). The know-how that the design team had gathered in the first years of testing ChADI 9 were subsequentially integrated into the LSA’s ultimate proposal not only to break the national, but also the absolute land speed record: with a new vehicle dubbed ChADI 9-II. This car was a completely new design, and its name was deliberately chosen in order to secure project budgets – it was easier to gain support for existing (and so far successful) projects rather than found new ones and convince superior powers of their value and success potential.
ChADI 9-II’s conceptual phase was launched in 1982 and it was basically a scaled-up evolution of ChADI 9, but it featured some significant differences. Instead of the RD-9 turbojet, the new vehicle was powered by a much more potent Tumansky R-25-300 afterburning turbojet with a dry thrust of 40.21 kN (9,040 lbf) and 69.62 kN (15,650 lbf) with full afterburner. This new engine (used and proven in the MiG-21 Mach 2 fighter) had already been thoroughly bench-tested by the Soviet Laboratory of High-Speed Automobiles in 1978, on an unmanned, tracked sled.
However, the development of ChADI 9-II and its details took more than two years of dedicated work by LSA ChADI’s students, and in 1984 the design was finally settled. The new vehicle was much bigger than its predecessor, 44 ft 10 in long, 15 ft 6¾ in wide, and 9 ft 10¾ in high (13.67 m by 4,75 m by 3,02 m), and it weighed around 9,000 lb (4 t). Its construction was based on a steel tube frame with an integrated security cell for the driver and an aluminum skin body, with some fibre glass elements. While ChADI 9’s slender cigar-shaped body with a circular diameter and the tricycle layout were basically retained, the front end of ChADI 9-II and its internal structure were totally different: instead of ChADI 9’s pointed nose, with the cockpit in the front and ahead of the vehicle’s front wheel and a pair of conformal (but not very efficient) side air intakes, ChADI 9-II featured a large, single orifice with a central shock cone. A small raked lower lip was to prevent FOD to the engine and act at the same time as a stabilizing front spoiler. The driver sat under a tight, streamlined canopy, the bifurcated air intake ducts internally flanking the narrow cockpit. Two steerable front wheels with a very narrow track were installed in front of the driver’s compartment. They were mounted side by side on a central steering pylon, which made them look like a single wheel. Behind the cockpit, still flanked by the air ducts, came two fuel tanks and finally, after a chamber where the air ducts met again, the engine compartment. Small horizontal stabilizers under the cockpit, which could be adjusted with the help of an electric actuator, helped keeping the vehicle’s nose section on the ground. Two small air brakes were mounted on the rear fuselage; these not only helped to reduce the vehicle’s speed, they could also be deployed in order to trim the aerodynamic downforce on the rear wheels. The latter ware carried on outriggers for a wide and stable track width and were covered in tight aerodynamic fairings, again made from fibre glass. The outriggers were furthermore swept back far enough so that the engine’s nozzle was placed in front of the rear wheel axis. This, together with a marked “nose-down” stance as well as a single swept fin on the rear above the afterburner nozzle with a brake parachute compartment, was to ensure stability and proper handling at expected speeds far in excess of 600 km/h (372 mph) without the use of the engine’s afterburner, and far more at full power.
Construction of ChADI 9-II lasted for more than another year, and in May 1986 the vehicle was rolled out and ready for initial trials at Chardiv, this time on the Chardiv State Aircraft Manufacturing Company’s runway. These non-public tests were successful and confirmed the soundness of the vehicle’s concept and layout. In the course of thorough tests until July 1987, ChADI 9-II was carefully pushed beyond the 400 km/h barrier and showed certain potential for more. This was the point when the vehicle was presented to the public (it could not be hidden due to the noisy trials within Chardiv’s city limits), and for this occasion (and marketing purposes) ChADI 9-II received a flashy livery in silver with red trim around the air intake and long the flanks and was officially christened with the more catchy title “„скорость“” (Skorost = Velocity).
Meanwhile, a potential area for serious high-speed trials had been identified with Lake Baskunchak, a salt sea near the Caspian Sea with flat banks that resembled the Bonneville Salt Flats in the USA. Lake Baskunchak became the site of further tests in 1988. Initially scheduled for May-July, the tests had to be postponed by six weeks due to heavy rain in the region, so that the sea would not build suitable dry salt banks for any safe driving tests. In late June the situation improved, and „скорость“ could finally take up its high speed tests.
During the following weeks the vehicle was gradually taken to ever higher speeds. During a test run on 8th of September, while travelling at roundabout 640 km/h (400 mph), one of the tail wheel fairings appeared to explode and the ensuing drag differences caused heavy oscillations that ended in a crash at 180 km/h (110 mph) with the vehicle rolling over and ripping the left rear wheel suspension apart.

This accident stopped the 1988 trials, but not the work on the vehicle. Another disaster struck the LSA ChADI team when ChADI 9, which was still operated, crashed in 1988, too, and had to be written off completely.
In mid-1989 and with only a single high speed vehicle left, LSA team appeared again with „скорость“ at the shores of Lake Baskunchak – and this time the weather was more gracious and the track could be used from late June onwards. Analyzing last year’s accident and the gathered data, the vehicle had undergone repairs and some major modifications, including a new, anti-corrosive paintjob in light grey with red and white trim.

On August 15, an officially timed record attempt was made, again with Victor Barchenkov at the steering wheel. The first of the two obligatory runs within an hour was recorded at a very promising 846.961 km/h (526.277 mph), but, at the end of the second run, „скорость“ veered off and no time was measured. Even worse, the vehicle lost its parachute brakes and went out of control, skidding away from the dry race track into Lake Baskunchak’s wet salt sludge, where it hit a ground wave at around 200 mph (320 km/h) and was catapulted through the air into a brine pond where it landed on its right side and eventually sank. Again, pilot Victor Barchenkov remained mostly unharmed and was able to leave the car before it sank – but this fatal crash meant the end of the „скорость“ vehicle and the complete KhAGI 9-II project. Furthermore, the break-up of the Soviet Union at the same time prevented and further developments of high speed vehicles. The whereabouts of the „скорость“ wreck remain unclear, too, since no official attempt had been made to save the vehicle’s remains from Lake Baskunchak’s salt swamps.

As an addition outside the model itself I also created a display base for the beauty pics, since I did not have anything at hand that would resemble the vastness of a flat and dry salt sea. The base is an 18x12” MDF board, on top of which I added a thin coat of white tile grout (which I normally use as a snow placebo, instead of plaster, which tends to absorb humidity over time and to become yellow). While the stuff was still wet I sprinkled some real salt onto the surface and wetted the whole affair with water sprays – hoping to create a flat yet structured surface with some glitter reflexes. And it actually worked!
Painting and markings:
I am not certain how ChADI 9 was painted (I assume overall silver), but I wanted for „скорость“ a little more color. Being a child of the Soviet era, red was a settled design element, but I thought that an all-red vehicle might have looked too cheesy. Other colors I considered were orange or white with blue trim, but did not find them to be appropriate for what I was looking. Eventually, I added some Russian Utilitarianism in the form of light grey for the upper hull (Humbrol 166, RAF Light Aircraft Grey), and the red (Humbrol 19) as a dark contrast around the complete air intake as well as the shock cone (somewhat inspired by the Green Monster #15 LSR vehicle), and then extended backwards into a narrowing cheatline along the flanks, which emphasizes the vehicle’s slender hull. For some more contrast between the two basic tones I later added thin white borders between them created with 2mm white decal stripes from TL Modellbau. Around the hull some bright red (Humbrol 238 Red Arrows Red) highlights as warning signs were added.
The vehicle’s afterburner section was painted with Modelmaster Steel Metallizer, the Panther wheels became Aluminum (Revell 99) with a black ink wash. Some black ink was also applied to the jet nozzle, so that the details became more pronounced, and some grinded graphite was used to enhance the burnt metal effect.
Since this would rather be an experimental car built and operated by a high school institute, and also operated in the Soviet Union, flashy sponsor markings would not be appropriate. Therefore I created some fictional marking at home with the help of PC software and printed them by myself. These designs included a fictional logo of the ChADI institute itself (created from a car silhouette drawing) and a logo for the vehicle’s title, “„скорость““. The latter was created from the cyrillic lettering, with some additions like the vehicle’s silhouette.
Unfortunately the production process for the home-made decals did not work properly – when coating the prints with gloss acrylic varnish the printer ink started to dissolve, bleeding magenta, so that the decals would look as if there was a red halo or glow around the otherwise black motifs. Thanks to the use of red in the vehicle’s overall design this flaw is not too apparent, so I stuck with the outcome and applied the decals to the car.
Beyond these basic markings, many stencils were added, including dull red inscriptions from an Italeri MiG-37 “Ferret” kit – finally, I found an expedient use for them! The Soviet flags on the fin came from an 1:144 Tu-144 airliner Braz Decal aftermarket sheet.
Finally, some panel lines were drawn onto the hull with a soft pencil and then the model was sealed with Italeri semi-gloss acrylic varnish. Just the black anti-glare panel in front of the windscreen became matt and the metallic rear section was left in “natural” finish.
I am very pleased with the outcome – the „скорость“ looks purposeful and does IMHO blend well into the line of spectacular USA and UK jet/rocket car designs that broke the 800 km/h barrier. I also find that, even though the MiG-21 ancestry is certainly there, the vehicle looks different enough so that the illusion that it was designed along the jet fighter’s lines (and not converted from one, like the real world “North American Eagle” which was built from an F-104 Starfighter) works well. I also think that the vehicle’s livery works well – it looks quite retro for a vehicle from the late Eighties, but that just adds to the “Soviet style”. An interesting project, outside of my normal comfort zone. :D

Some background:
The Lockheed P-80 Shooting Star was the first jet fighter used operationally by the United States Army Air Forces (USAAF) during World War II. Designed and built by Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. The XP-80 had a conventional all-metal airframe, with a slim low wing and tricycle landing gear. Like most early jets designed during World War II—and before the Allies captured German research data that confirmed the speed advantages of swept-wings—the XP-80 had straight wings similar to previous propeller-driven fighters, but they were relatively thin to minimize drag at high speed.
The Shooting Star began to enter service in late 1944 with 12 pre-production YP-80As. Four were sent to Europe for operational testing (demonstration, familiarization, and possible interception roles), two to England and two to the 1st Fighter Group at Lesina Airfield, Italy. Because of delays in delivery of production aircraft, the Shooting Star saw no actual combat during the conflict. The initial production order was for 344 P-80As after USAAF acceptance in February 1945. A total of 83 P-80s had been delivered by the end of July 1945 and 45 assigned to the 412th Fighter Group (later redesignated the 1st Fighter Group) at Muroc Army Air Field. Production continued after the war, although wartime plans for 5,000 were quickly reduced to 2,000 at a little under $100,000 each. A total of 1,714 single-seat F-80A, F-80B, F-80C, and RF-80s were manufactured by the end of production in 1950, of which 927 were F-80Cs (including 129 operational F-80As upgraded to F-80C-11-LO standards). However, the two-seat TF-80C, first flown on 22 March 1948, became the basis for the T-33 trainer, of which 6,557 were produced.
Shooting Stars first saw combat service in the Korean War, and were among the first aircraft to be involved in jet-versus-jet combat. Despite initial claims of success, the speed of the straight-wing F-80s was inferior to the 668 mph (1075 km/h) swept-wing transonic MiG-15. The MiGs incorporated German research showing that swept wings delayed the onset of compressibility problems, and enabled speeds closer to the speed of sound. F-80s were soon replaced in the air superiority role by the North American F-86 Sabre, which had been delayed to also incorporate swept wings into an improved straight-winged naval FJ-1 Fury.
This prompted Lockheed to improve the F-80 to keep the design competitive, and the result became the F-80E, which was almost a completely different aircraft, despite similar outlines. Lockheed attempted to change as little of the original airframe as possible while the F-80E incorporated two major technical innovation of its time. The most obvious change was the introduction of swept wings for higher speed. After the engineers obtained German swept-wing research data, Lockheed gave the F-80E a 25° sweep, with automatically locking leading edge slots, interconnected with the flaps for lateral stability during take-off and landing, and the wings’ profile was totally new, too. The limited sweep was a compromise, because a 35° sweep had originally been intended, but the plan to retain the F-80’s fuselage and wing attachment points would have resulted in massive center of gravity and mechanical problems. However, wind tunnel tests quickly revealed that even this compromise would not be enough to ensure stable flight esp. at low speed, and that the modified aircraft would lack directional stability. The swept-wing aircraft’s design had to be modified further.
A convenient solution came in the form of the F-80’s trainer version fuselage, the T-33, which had been lengthened by slightly more than 3 feet (1 m) for a second seat, instrumentation, and flight controls, under a longer canopy. Thanks to the extended front fuselage, the T-33’s wing attachment points could accept the new 25° wings without much further modifications, and balance was restored to acceptable limits. For the fighter aircraft, the T-33’s second seat was omitted and replaced with an additional fuel cell. The pressurized front cockpit was retained, together with the F-80’s bubble canopy and out fitted with an ejection seat.
The other innovation was the introduction of reheat for the engine. The earlier F-80 fighters were powered by centrifugal compressor turbojets, the F-80C had already incorporated water injection to boost the rather anemic powerplant during the start phase and in combat. The F-80E introduced a modified engine with a very simple afterburner chamber, designated J33-A-39. It was a further advanced variant of the J33-A-33 for the contemporary F-94 interceptor with water-alcohol injection and afterburner. For the F-80E with less gross weight, the water-alcohol injection system was omitted so save weight and simplify the system, and the afterburner was optimized for quicker response. Outwardly, the different engine required a modified, wider tail section, which also slightly extended the F-80’s tail.
The F-80E’s armament was changed, too. Experience from the Korean War had shown that the American aircrafts’ traditional 0.5” machine guns were reliable, but they lacked firepower, esp. against bigger targets like bombers, and even fighter aircraft like the MiG-15 had literally to be drenched with rounds to cause significant damage. On the other side, a few 23 mmm rounds or just a single hit with an explosive 37 mm shell from a MiG could take a bomber down. Therefore, the F-80’s six machine guns in the nose were replaced with four belt-fed 20mm M24 cannon. This was a license-built variant of the gas-operated Hispano-Suiza HS.404 with the addition of electrical cocking, allowing the gun to re-cock over a lightly struck round. It offered a rate of fire of 700-750 rounds/min and a muzzle velocity of 840 m/s (2,800 ft/s).In the F-80E each weapon was provided with 190 rounds.
Despite the swept wings Lockheed retained the wingtip tanks, similar to Lockheed’s recently developed XF-90 penetration fighter prototype. They had a different, more streamlined shape now, to reduce drag and minimize the risk of torsion problems with the outer wing sections and held 225 US gal (187 imp gal; 850 l) each. Even though the F-80E was conceived as a daytime fighter, hardpoints under the wings allowed the carriage of up to 2.000 lb of external ordnance, so that the aircraft could, like the straight-wing F-80s before, carry out attack missions. A reinforced pair of plumbed main hardpoints, just outside of the landing gear wells, allowed to carry another pair of drop tanks for extra range or single bombs of up to 1.000 lb (454 kg) caliber. A smaller, optional pair of pylons was intended to carry pods with nineteen “Mighty Mouse” 2.75 inches (70 mm) unguided folding-fin air-to-air rockets, and further hardpoints under the outer wings allowed eight 5” HVAR unguided air-to-ground rockets to be carried, too. Total external payload (including the wing tip tanks) was 4,800 lb (roughly 2,200 kg) of payload
The first XP-80E prototype flew in December 1953 – too late to take part in the Korean War, but Lockheed kept the aircraft’s development running as the benefits of swept wings were clearly visible. The USAF, however, did not show much interest in the new aircraft since the proven F-86 Sabre was readily available and focus more and more shifted to radar-equipped all-weather interceptors armed with guided missiles. However, military support programs for the newly founded NATO, esp. in Europe, stoked the demand for jet fighters, so that the F-80E was earmarked for export to friendly countries with air forces that had still to develop their capabilities after WWII. One of these was Germany; after World War II, German aviation was severely curtailed, and military aviation was completely forbidden after the Luftwaffe of the Third Reich had been disbanded by August 1946 by the Allied Control Commission. This changed in 1955 when West Germany joined NATO, as the Western Allies believed that Germany was needed to counter the increasing military threat posed by the Soviet Union and its Warsaw Pact allies. On 9 January 1956, a new German Air Force called Luftwaffe was founded as a branch of the new Bundeswehr (Federal Defence Force). The first volunteers of the Luftwaffe arrived at the Nörvenich Air Base in January 1956, and the same year, the Luftwaffe was provided with its first jet aircraft, the US-made Republic F-84 Thunderstreak from surplus stock, complemented by newly built Lockheed F-80E day fighters and T-33 trainers.
A total of 43 F-80Es were delivered to Germany in the course of 1956 and early 1957 via freight ships as disassembled kits, initially allocated to WaSLw 10 (Waffenschule der Luftwaffe = Weapon Training School of the Luftwaffe) at Nörvenich, one of three such units which focused on fighter training. The unit was quickly re-located to Northern Germany to Oldenburg, an airfield formerly under British/RAF governance, where the F-80Es were joined by Canada-built F-86 Sabre Mk. 5s. Flight operations began there in November 1957. Initially supported by flight instructors from the Royal Canadian Air Force from Zweibrücken, the WaSLw 10’s job was to train future pilots for jet aircraft on the respective operational types. F-80Es of this unit were in the following years furthermore frequently deployed to Decimomannu AB on Sardinia (Italy), as part of multi-national NATO training programs.
The F-80Es’ service at Oldenburg with WaSLw 10 did not last long, though. In 1963, basic flight and weapon system training was relocated to the USA, and the so-called Europeanization was shifted to the nearby Jever air base, i. e. the training in the more crowded European airspace and under notoriously less pleasant European weather conditions. The remaining German F-80E fleet was subsequently allocated to the Jagdgeschwader 73 “Steinhoff” at Pferdsfeld Air Base in Rhineland-Palatinate, where the machines were – like the Luftwaffe F-86s – upgraded to carry AIM-9 Sidewinder AAMs, a major improvement of their interceptor capabilities. But just one year later, on October 1, 1964, JG 73 was reorganized and renamed Fighter-Bomber Squadron 42, and the unit converted to the new Fiat G.91 attack aircraft. In parallel, the Luftwaffe settled on the F-86 (with more Sabre Mk. 6s from Canada and new F-86K all-weather interceptors from Italian license production) as standard fighter, with the plan to convert to the supersonic new Lockheed F-104 as standard NATO fighter as soon as the type would become available.
For the Luftwaffe the F-80E had become obsolete, and to reduce the number of operational aircraft types, the remaining German aircraft, a total of 34, were in 1965 passed through to the Türk Hava Kuvvetleri (Turkish air force) as part of international NATO military support, where they remained in service until 1974 and were replaced by third generation F-4E Phantom II fighter jets.

The kit and its assembly:
The idea of a swept-wing F-80 had been lingering on my idea list for a while, and I actually tried this stunt before in the form of a heavily modified F-94. The recent “Fifties” group build at whatifmodellers.com and a similar build by fellow forum member mat revived the interest in this topic – and inspired by mat’s creation, based on a T-33 fuselage, I decided to use the opportunity and add my personal interpretation of the idea.
Having suitable donor parts at hand was another decisive factor to start this build: I had a Heller T-33 in store, which had already been (ab)used as a donor bank for other projects, and which could now find a good use. I also had an F-80 canopy left over (from an Airfix kit), and my plan was to use Saab J29 wings (from a Matchbox kit) because of their limited sweep angle that would match the post-WWII era well.
Work started with the fuselage; it required a completely new cockpit interior because these parts had already gone elsewhere. I found a cockpit tub with its dashboard from an Italeri F4U, and with some trimming it could be mounted into the reduced cockpit opening, above the OOB front landing gear well. The T-33’s rear seat was faired of with styrene sheet and later PSRed away. The standard nose cone from the Heller T-33 was used, but I added gun ports for the new/different cannon armament.
For a different look with an afterburner engine I modified the tail section under the stabilizers, which was retained because of its characteristic shape. A generous section from the tail was cut away and replaced with the leftover jet pipe from an Italeri (R)F-84F, slightly longer and wider and decorated with innards from a Matchbox Mystère IV. This change is rather subtle but changes the F-80 profile and appears like a compromise between the F-80 and F-94 arrangements.
The T-33 wings were clipped down to the connection lower fuselage part. This ventral plate with integral main landing gear wells was mounted onto the T-33 hull and then the Saab 29 wings were dry-fitted to check their position along the fuselage and to define the main landing gear wells, which had to be cut into them to match their counterparts from the aircraft’s belly.
Their exact position was eventually fixed when the new swept stabilizers, taken from a Hobby Boss F-86, were mounted to the tail. They match well with the swept wings, and for an odd look I kept their dihedral.
The fin was eventually replaced, too – mat’s build retained the original F-80 fin, but with all other surfaces swept I found that the fin had to reflect this, too. So, I implanted a shortened Italeri (R)F-84F fin onto the original base, blended with some PSR into the rest of the tail.
With all aerodynamic surfaces in place it was time for fine-tuning, and to give the aircraft a simpler look I removed the dog teeth from the late Tunnan's outer wings, even though I retained the small LERXs. The wing tips were cut down a little and tip tanks (probably drop tanks from a Hobby Boss F-5E) added – without them the aircraft looked like a juvenile Saab 32!
The landing gear was mostly taken over from the Heller T-33, I just added small consoles for the main landing gear struts to ensure a proper stance, because the new wings and the respective attachment points were deeper. I also had to scratch some landing gear covers because the T-33 donor kit was missing them. The canopy was PSRed over the new opening and a new ejection seat tailored to fit into the F4U cockpit.
A final addition was a pair of pods with unguided FFARs. AFAIK the Luftwaffe did not use such weapons, but they’d make thematically sense on a Fifties anti-bomber interceptor - and I had a suitable pair left over from a Matchbox Mystère IV kit, complete with small pylons.
Painting and markings:
Since the time frame was defined by the Fifties, early Luftwaffe fighters had to carry a bare metal finish, with relatively few decorations. For the F-80E I gave the model an overall base coat with White Aluminum from a Dupli Color rattle can, a very nice and bright silver tone that comes IMHO close to NMF. Panels were post-shaded with Revell 99 (Aluminum) and 91 (Iron Metallic). An anti-glare panel in front of the windscreen was painted in the Luftwaffe tone RAL 6014, Gelboliv (Revell 42).
For some color highlights I gave the tip tanks bright red (Feuerrot, RAL 3000; Revell 330) outer halves, while the inner halves were painted black to avoid reflections that could distract the pilot (seen on a real Luftwaffe T-33 from the late Fifties). For an even more individual touch I added light blue (Tamiya X-14, Sky Blue) highlights on the nose and the fin, reflecting the squadron’s color code which is also carried within the unit emblem – the Tamiya paint came closest to the respective decal (see below).
The cockpit interior was painted with zinc chromate green primer (I used Humbrol 80, which is brighter than the tone should be, but it adds contrast to the black dials on the dashboard), the landing gear wells were painted with a mix of Humbrol 80 and 81, for a more yellowish hue. The landing gear struts became grey, dry-brushed with silver, while the inside of the ventral air brakes were painted in Feuerrot, too.
Then the model received an overall washing with black ink to emphasize the recessed panel lines, plus additional panel shading with Matt Aluminum Metallizer (Humbrol 27001), plus a light rubbing treatment with grinded graphite that emphasized the (few leftover) raised panel lines and also added a dark metallic shine to the silver base. Some of the lost panel lines were simulated with simple pencil strokes, too.
The decals/markings primarily came from an AirDoc aftermarket sheet for late Fifties Luftwaffe F-84Fs. The tactical code (“BB-xxx” was then assigned to the WaSLw 10 as unit code, but this soon changed to a similar but different format that told about the unit’s task as well as the specific unit and squadron within it; this was replaced once more by a simple xx+yy code that was only connected to a specific aircraft with no unit reference anymore, and this format is still in use today) was puzzled together from single letters/digits from the same decal set. Some additional markings like the red band on the fuselage had to be scratched, but most stencils came from an all-bare-metal Luftwaffe F-84F.
After some more detail painting the model was sealed with semi-gloss acrylic paint, just the anti-glare panel and the di-electric fairings on the nose and the fin tip became matt.
A thorough kitbashing build, but the result looks quite plausible, if not elegant? The slightly swept wings suit the F-80 with its organic fuselage shape well, even though they reveal the designs rather baroque shape. There’s a sense of obsolescence about the F-80E, despite its modern features? The Luftwaffe markings work well on the aircraft, too, and with the red and blue highlights the machine looks more attractive despite its simple NMF livery than expected.

Development studies at Grumman for jet-powered fighter aircraft began near the end of World War II as the first jet engines emerged. In a competition for a jet-powered night fighter for the United States Navy, on 3 April 1946 the Douglas F3D Skyknight was selected over Grumman's G-75, a two-seater powered by four Westinghouse J30s. The Navy's Bureau of Aeronautics (BuAer) also issued a contract to Grumman for two G-75 prototype aircraft on 11 April 1946, in case the Skyknight ran into problems.
However, Grumman soon realized that the G-75 was a dead end. But the company had been working on a completely different day fighter, the G-79, which offered a higher potential. In order to keep Grumman in the US Navy’s procurement loop, BuAer, in a bureaucratic maneuver, did not cancel the G-75 contract, but changed the wording to include prototypes of the entirely different G-79, too.
The G-79 project comprised a total of four different layouts and engine arrangements for a single seat fighter aircraft. G-79A and B were traditional tail sitters, but both featured mixed propulsion for an enhanced performance: G-79A was powered by an R-2800 radial engine and a Rolls Royce Derwent VI jet booster in the tail, fed by a pair of dorsal air intakes behind the cockpit. The G-79B was a similar aircraft, but its primary engine was a General Electric TG-100 turboprop in a more slender nose section. Even though both designs were big aircraft, initial calculations indicated a performance that would be superior to the Grumman F8F Bearcat, which had been designed as a thoroughbred interceptor.
The other two designs were pure jet fighters, both with a tricycle landing gear. G-79C had a layout reminiscent of the Gloster Meteor and was powered by two Derwent VI engines in bulky wing nacelles, and G-79D was finally an overall smaller and lighter aircraft, similar in its outlines to the early Vought F6U Pirate, and powered by a single Nene in the rear fuselage, fed by air intakes in the wing roots.
Since the operation of jet-powered aircraft from carriers was terra incognita for the US Navy, and early turbojets thirsty and slow to react to throttle input, BuAer decided to develop two of Grumman's G-79 designs into prototypes for real life evaluation: one of the conservative designs, as a kind of safe route, and one of the more modern jets.
From the mixed propulsion designs, the turboprop-powered G-79B was chosen (becoming the XF9F-1 'JetCat'), since it was expected to offer a higher performance and development potential than the radial-powered 'A'. From the pure jet designs the G-79D was chosen, because of its simplicity and compact size, and designated XF9F-2 'Panther'.
The first JetCat prototype made its maiden flight on 26 October 1947, but it was only a short airfield circuit since the TG-100 turpoprop failed to deliver full power and the jet booster had not been installed yet. The prototype Panther, piloted by test pilot Corky Meyer, first flew on 21 November 1947 without major problems.
In the wake of the two aircrafts' test program, several modifications and improvements were made. This included an equal armament of four 20mm guns (mounted in the outer, foldable wings on the JetCat and, respectively, in the Panther’s nose). Furthermore, both aircraft were soon armed with underwing HVAR air-to-ground rockets and bombs, and the JetCat even received an underfuselage pylon for the potential carriage of an airborne torpedo. Since there was insufficient space within the foldable wings and the fuselage in both aircraft for the thirsty jet’s fuel, permanently mounted wingtip fuel tanks were added on both aircraft, which incidentally improved the fighters' rate of roll. Both F9F types were cleared for flight from aircraft carriers in September 1949.
The F9F-1 was soon re-engined with an Allison T38 turboprop, which was much more reliable than the TF-100 (in the meantime re-designated XT31) and delivered a slightly higher power output. Another change was made for the booster: the bulky Derwent VI engine from the prototype stage was replaced by a much more compact Westinghouse J34 turbojet, which not only delivered slightly more thrust, it also used up much less internal space which was used for radio and navigation equipment, a life raft and a relocated oil tank. Due to a resulting CG shift towards the nose, the fuselage fuel cell layout had to be revised. As a consequence, the cockpit was moved 3’ backwards, slightly impairing the pilot’s field of view, but it was still superior to the contemporary Vought F4U.
Despite the engine improvements, though, the F9F-1 attained markedly less top speed than the F9F-2. On the other side, it had a better rate of climb and slow speed handling characteristics, could carry more ordnance and offered a considerably bigger range and extended loiter time. The F9F-2 was more agile, though, and more of the nimble dogfighter the US Navy was originally looking for. Its simplicity with just a single engine was appealing, too.
The Panther was eventually favored as the USN's first operational jet day fighter and put into production, but the F9F-1 showed much potential as a fast fighter bomber. Through pressure from the USMC, who was looking for a replacement for its F7F heavy Tigercat fighters, a production order for 50 JetCats was eventually placed, later augmented to 82 aircraft because the US Navy also recognized the type’s potential as a fast, ship-borne multi-role fighter. Further interest came in 1949 from Australia, when the country’s government was looking for a - possibly locally-built in license - replacement for the outdated Mustang Mk 23 and De Havilland Vampire then operated by the Royal Australian Air Force (RAAF). Both Grumman designs were potential contenders, rivalling with the domestic CAC CA-23 fighter development.
The Grumman Panther became the most widely used U.S. Navy jet fighter of the Korean War, flying 78,000 sorties and scoring the first air-to-air kill by the U.S. Navy in the war, the downing of a North Korean Yakovlev Yak-9 fighter. Being rugged aircraft, F9F-2s, -3s and -5s were able to sustain operations, even in the face of intense anti-aircraft fire. The pilots also appreciated the Panther’s air conditioned cockpit, which was a welcome change from the humid environment of piston-powered aircraft.
The F9F-1 did fare less glamorous. Compared with the prototypes, the T38 turboprop's power output could be enhanced on service aircraft, but not on a significant level. The aircraft's original, rather sluggish response to throttle input and its low-speed handling were improved through an eight-blade contraprop, which, as a side benefit, countered torque problems during starts and landings on carriers.
The JetCat’s mixed powerplant installation remained capricious, though, and the second engine and its fuel meant a permanent weight penalty. The aircraft's complexity turned out to be a real weak point during the type's deployment to front line airfields in the Korean War, overall readiness was – compared with conservative types like the F4U and also the F9F-2, low. Despite the turboprop improvements, the jet booster remained necessary for carrier starts and vital in order to take on the MiG-15 or post-war piston engine types of Soviet origin like the Lavochkin La-9 and -11 or the Yakowlev Yak-9.
Frequent encounters with these opponents over Korea confirmed that the F9F-1 was not a “naturally born” dogfighter, but rather fell into the escort fighter or attack aircraft class. In order to broaden the type's duty spectrum, a small number of USMC and USN F9F-1s was modified in field workshops with an APS-6 type radar equipment from F4U-4N night fighters. Similar to the Corsair, the radar dish was carried in a streamlined pod under the outer starboard wing. The guns received flame dampers, and these converted machines, re-designated F9F-1N, were used with mild success as night and all-weather fighters.
However, the JetCat remained unpopular among its flight and ground crews and, after its less-than-satisfactory performance against MiGs, quickly retired. After the end of the Korean War in July 1953, all machines were grounded and by 1954 all had been scrapped. However, the turboprop-powered fighter bomber lived on with the USMC, which ordered the Vought A3U SeaScorpion as successor.

The kit and its assembly:
This is another submission to the Cold War GB at whatifmodelers in early 2018, and rather a spontaneous idea. It was actually spawned after I finished my fictional Gudkov Gu-1 mixed propulsion fighter - while building (using the engine front from an F6F Hellcat) I had the impression that it could also have ended up as a post-war USN fighter design.
A couple of days later, while browsing literature for inspiration, I came across Grumman's G-79 series of designs that eventually led to the F9F Panther - and I was amazed that the 'A' design almost looked like my kitbashed Soviet fighter!
So I considered a repeated build of a P-47D/Supermarine Attacker kitbash, just in American colors. But with the F9F relationship, I planned the integration of Panther parts, so that the new creation would look different from the Gu-1, but also show some (more) similarity to the Panther.
The plan appeared feasible. Again, the aircraft's core is an Academy P-47D, with its outer wings cut off. Cockpit and landing gear were retained. However, instead of Supermarine Attacker wings from a Novo kit, I attached F9F-2 wings from a Hasegawa kit. Shape-wise this worked fine, but the Panther wings are much thinner than the Thunderbolt’s, so that I had to integrate spacers inside of the intersections which deepen the Hasegawa parts. Not perfect, but since the type would feature folding wings, the difference and improvisation is not too obvious.
On the fuselage, the Thunderbolt’s air outlets on its flanks were faired over and most of the tail section cut away. In the lower part of the tail, a jet pipe (from a Heller F-84G) was added and blended with PSR into the Thunderbolt fuselage, similar to the Gu-1. A completely new fin was scratched from an outer wing section from a Heinkel He 189, in an attempt to copy the G-79B's shape according to the drawing I used as benchmark for the build. I also used the F9F's stabilizers. With clipped tips they match well in size and shape, and add to the intended Grumman family look. The original tail wheel well was retained, but the tail wheel was placed as far back as possible and replaced by the twin wheel from a Hasegawa F5U. The Panther’s OOB tail hook was integrated under the jet pipe, too.
The front section is completely different and new, and my choice fell on the turboprop-powered G-79B because I did not want to copy the Gu-1 with its radial engine. However, the new turboprop nose was not less complicated to build. Its basis is a 1:100 engine and contraprop from a VEB Plasticart Tu-20/95 bomber, a frequent ingredient in my builds because it works so well in 1:72 scale. This slender core was attached to the Thunderbolt's fuselage, and around this basis a new cowling was built up with 2C putty, once more in an attempt to mimic the original G-79B design as good as possible.
In order to blend the new engine with the fuselage and come close to the G-79B’s vaguely triangular fuselage diameter, the P-47's deep belly was cut away, faired over with styrene sheet, and everything blended into each other with more PSR work. As a final step, two exhaust pipes were mounted to the lower fuselage in front of the wings’ leading edge.
The air intakes for the jet booster are actually segments from a Sopwith Triplane fuselage (Revell) – an unlikely source, but the shape of the parts was just perfect. More PSR was necessary to blend them into the aircraft’s flanks, though.
Painting and markings:
As per usual, I'd rather go with conservative markings on a fictional aircraft. Matching the Korean War era, the aircraft became all-over FS 35042 (Modelmaster). A black ink wash emphasized the partly re-engraved panel lines, and some post shading highlighted panels.
The wings’ leading edges and the turboprop’s intake were painted with aluminum, similar edges on fin and stabilizers were created with silver decal material. The interior of cockpit and landing gear was painted with green chromate primer.
The markings were puzzled together. “Stars and Bars” and VF-53 markings were taken from a Hobby Boss F4U-4 kit. The blue fin tip is the marking for the 3rd squadron, so that the “307” tactical code is plausible, too (the latter comes from a Hobby Boss F9F-2). In order to keep things subtle and more business-like (after all, the aircraft is supposed to be operated during the ongoing Korean War), I did not carry the bright squadron color to any other position like the spinner or the wing tips.
After some final detail work and gun and exhaust soot stains, the kit was sealed with semi-gloss acrylic varnish (Italeri). Matt acrylic varnish was used for weathering effects, so that the aircraft would not look too clean and shiny.
While it is not a prefect recreation of the Grumman G-79B, I am quite happy with the result. The differences between the model and the original design sketch can be explained through serial production adaptations, and overall the whole thing looks pretty conclusive. In fact, the model appears from certain angles like a naval P-51 on steroids, even though the G-79B was a much bigger aircraft than the Mustang.
An original vampiric character, and 1/6 scale kitbash figure of my own devising, photographed employing layered filters from Enjoyphoto, Photoshop, Superphoto and default editing apps on my cameraphone.
The notion behind this character (part of an ongoing project) is to create an 'anti-Buffy': a mortal agent, bound by blood, and devoted to a Vampyre Lord and the interests of its House.
New pics form an old kit - and a special one it is. Even though there are Valkyrie kits with the FAST packages for deep space use available, this is a self-made conversion with many extra parts from various Valkyrie kits and some extra "functions".
The basis originally wa a normal amd rather simple 1:100 ARII Battroid mode VF-1A kit. But legs, arms and especially the torso were modified, or replaced with "better" donation parts.
Besides the FAST pack additions, the legs received additional joints in the thighs. The hip mounting was totally mofidied to allow 3D movement of the legs - it is a completely different lower body part from a transformable IMAI 1:100 Valkyrie.
The lower arms also received FAST pack additions (which include more detailed missiles, from the Valkyrie fighter mode kits) and further additional joints in the upper arms as well as new, more delicate hands to give a more agile impression. The latter come from leftover Dorvack PA-58 Powered Armors kits, actually they are 1:24th scale!
In order to keep the proportions of the more slender lower body from the transformable kit in tune with the upper torso, the latter had to be elongated.
The upper body's back side was totally modified to hold moveable wings, also from a transformable Valkyire kit in 1:100. Thorugh this huge modification the wings can now actually be swung into landing position, and even seperate rocket pods can be added in 4 vinyl caps! On the downside, the wings in forward position prevent free movement of the arms... one of the mysteries that surround the VF-1's construction. ;)
The FAST rocket boosters on the back* are leftover standard pieces from a 1:100 scale Bandai VF-1 Gerwalk kit, but also modified in detail.
Finally, the color scheme: it is a standard pattern of Roy Fokker's "Skull" squadron, just displaying a Valkyrie "from the lot", nothing specific.
Basis is an overall satin white, and almost all squadron markings in black and blue were applied with paint and by hand, since no decals for this "version" were available at the time of making.
* For the die-hard fans: this depicted weapon/Battroid arrangement is not authentic. The Rö-X2A shoulder laser can (according to Macross folklore) only be mounted on VF-1S Valkyries, the A, J and D versions only take the "simple" rocket pods. But it looks cool...! ;)
Painting and markings:
Finding a suitable and somewhat interesting – but still plausible – paint scheme was not easy. Taking the A-10 as benchmark, an overall light grey livery (with focus on low contrast against the sky as protection against ground fire) would have been a likely choice – and in fact the last operational American OV-10s were painted in this fashion. But in order to provide a different look I used the contemporary USAF V-22Bs and Special Operations MC-130s as benchmark, which typically carry a darker paint scheme consisting of FS 36118 from above, FS 36375 underneath (with a low, wavy waterline), plus low-viz markings. Not spectacular, but plausible – and very similar to the late r/w Colombian OV-10s, and its suitable “Gunship Gray”. :D
The cockpit tub became Dark Gull Grey (FS 36231, Humbrol 140) and the landing gear white (Revell 301).
The model received an overall black ink washing and some post-panel-shading, to liven up the dull all-grey livery. The decals were gathered from various sources, and I settled for black USAF low-viz markings. The “stars and bars” come from a late USAF F-4, the “IP” tail code was tailored from F-16 markings and the shark mouth from an Academy AH-64. Most stencils came from another Academy OV-10 sheet and some other sources.
Decals were also used to create the trim on the propeller blades and markings on the ordnance.
Some background:
Instead of a story compiled/edited by myself, a very good “real” source: an article about the “American Spirit” project from 1996, scanned from a magazine and posted elsewhere:
This and some more information, including a drawing of the (apparently never) finished aircraft and a photo of the semi-finished airframe on airliners.net were the basis for my build.
The kit and its assembly:
This is my third and last entry to the “Racing” group build at whatifmodelers.com that ended in Feb. 2019. It is nothing less than the attempt to re-create the potentially fastest piston engine aircraft in the world as a model, based on the sparse information I was able to gather (see above). The aircraft’s design is quite odd, and it is worth reading the design background in the article, because it was a true “garage build” with the intention to use as many existing components in order to save costs and development time.
This was, more or less, mirrored during the building process, and like the real “American Spirit” the model consists at its core of a Matchbox T-2 “Buckeye” jet trainer! The T-2 fuselage lost its nose section, the ventral engine bay and the original cockpit fairing. This left a lot of fuselage surface to be re-constructed. The fin was clipped, too, just like in real life. At the fin’s base I added a cockpit opening and implanted a cockpit tub, taken from a Revell G.91. A new bucket seat (probably from an Academy Fw 190) was installed, and a new, tight canopy – I think it originally came from a Revell Go 229, but it was trimmed down considerably to match the T-2’s fuselage lines. The canopy was blended into the fin root with massive 2C putty sculpting, and the area in front of the windscreen was created with 2C putty, too. Both a tedious PSR process.
Once the upper fuselage shape was finished I started searching for a cowling and a matching propeller. After several attempts with bigger engines (e. g. from a Super Constellation) I eventually settled upon a rather narrow (but bleak) cowling from an Pioneer2/Airfix Hawker Sea Fury, which turned out to have just the right diameter for the re-constructed T-2 fuselage and matched the “American Spirit” drawing’s well.
It also had at the front end the right diameter for the propeller: it comes, just like in real life, from a C-130 Hercules, even though I used a late variant with six blades, a resin aftermarket piece, taken from an Attack Squadron engine nacelle set. Unfortunately, the spinners were molded onto the engines, so that I had to cut my donor part away. Three of the six propeller blade attachment points were faired over. While the original “American Spirit” carried clipped blades from an Electra airliner, I used parts from a P-3 Orion – the come very close in shape and size, and were easy to install. Finally, the propeller received a metal axis and a matching styrene tube adapter in the Sea Fury cowling.
Once the engine was in place, the cowling was filled with as much lead as possible, since the model would be built with an extended landing gear.
However, a large ventral section was still missing, and it was created with a leftover underwater section from a model ship hull, and lots of more putty, of course. A small tail bumper was added under the fin.
Once the fuselage was more or less finished, I turned my attention to the wings and stabilizers. The latter were supposed to be “un-swept F-86H stabilizers”, but unfortunately I could not find visual evidence of what this would have looked like. I tried some donor parts, including stabilizers from an F-86A and D, as well as from a MiG-15, and eventually decided to use individual parts, because nothing looked convincing to me, either swept or straight. Actually the MiG-15 parts looked the best, but they were too small, so I used the wings from an 1:144 Panavia Tornado (Dragon) and tailored them into a sweep angle similar to the MiG-15 parts, but with more depth and span. Not certain how “realistic” this is, but it looks good and compliments the swept T-2 fin well.
The T-2 wings saw only minor modifications: the wing tip tanks were cut off and the tips as well as the flaps faired over, since the “American Spirit” did not feature the latter anymore. The small LERXs were cut away, too, and instead I added small air intakes – the “American Spirit” probably did not feature them, but I wondered where the aircraft’s engine would feed its carburetor or an oil cooler? The respective gaps on the fuselage flanks were filled accordingly.
Some more work waited on the fuselage, too. The aircraft’s drawing showed shallow openings on the forward fuselage’s flanks, but their function was not clear – I assume that the exhausts from the 18 cylinder engine were collected there, 9 on each side, so I carved the openings into the massive plastic and putty fuselage with a mini drill tool and added exhaust stubs as well as deflector plates.
Another issue was the well for the front landing gear – this came, together with the complete front leg, from an Italeri F-100, just like in real life. The good thing about the Italeri kit is that it comes with a separate well tub, which made the installation quite easy. I just cut a square section out of the lower fuselage behind the engine and the landing gear well snuggly fell into place, with only little PSR effort. And, to my surprise, the end result seems to be a very good match to the real life design – even though I was not able to confirm this with picture material.
The main landing gear was taken OOB from the Matchbox T-2 – and it is really a weird sight, since the T-2’s track is very wide while the wheelbase is unusually short. But the source article indicates that this must have been the designers’ plans!
Painting and markings:
While the model’s hardware came quite close to the real thing, the livery of the “American Spirit” was totally open, so I created my own. I felt that two design directions would be appropriate: either a relatively dry and clean design, e. g. in overall silver or white with a little trim, or something patriotic, reflecting the aircraft’s name.
I eventually settled for the latter, and considered several approaches in white, red and blue, and eventually settled for one of my first ideas, a kind of “flying American flag” in an asymmetrical design, somewhat inspired by a Bicentennial F-106A from 1976: this machine carried a white fuselage with some red trim stripes and a blue nose section that featured lots of tiny white stars. I took this layout a little further and gave the “American Spirit” a dark blue engine cowling and front fuselage section, as well as a single blue wing. From that, wide red and white stripes stream backwards across the other wing, the fuselage and the tail. The design was mirrored on the undersides.
The stripes were painted with a wide brush with Humbrol 19 and 22, after the kit had been primed with white and had received an overall white basic coat with acrylic paint from the rattle can, too. The blue section was painted with Revell 350 (RAL 5013/Lufthansa Blue). I tried to add some “wavy flag texture” effect to the basic paints with slightly different tones, added wet-in-wet to the basic paints, but the visual effect turned out to be minimal, so I left it like that.
The stars are all individual waterslide decals, coming from an 1:87 Allied WWII markings sheet from TL Modellbau. The big white stars that are the background for the starting numbers on top and below the blue wing come from an 1:72 F4U. The red and blue starting numbers themselves were taken from a TL Modellbau sheet for firefighting vehicles: they are actually parts of German emergency telephone numbers…
Some stencils and leading edges on all wings, created with generic silver decal material, completed the outside, and finally I painted some fake panel lines onto the hull with a soft pencil. The T-2 air brakes, which were retained for the “American Spirit”, were re-created with fine black decal lines. Similar material in silver was used to simulate panel lines for the cooling air outlet flaps on the cowling. Unfortunately, the T-2 kit itself did not come with much surface detail, and any leftover rest (like the air brakes) disappeared during the extensive PSR sessions and under the primer and paint coats. Finally, the kit was sealed with a coat of semi-gloss acrylic varnish (Italeri).
A massive scratch-build. While challenging the work on this model was fun because it followed in its creation a similar process as the real “American Spirit”, which was, AFAIK, sold and never completed. In the end, I am positively surprised how close the overall outlines seem to come to the real (and odd-looking) aircraft, even though the garish livery is purely speculative, so that this model is, despite its roots in the real world and the attempt to stay true to the original, a fictional/whif piece. The finish is a bit rough, though, but that’s probably the price to pay when you create things from scratch.
I kitbashed the Power Girl figure using the Jiaou doll instead of using the Tbleague body since the Jiaou seems much more curvey than the Tbleague bodies , especially the lower half of the bodies and she filled her suit a whole lot better .

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
After the success of the Soviet Union’s first carrier ship, the Moskva Class (Projekt 1123, also called „Кондор“/„Kondor“) cruisers in the mid 1960s, the country became more ambitious. This resulted in Project 1153 Orel (Russian: Орёл, Eagle), a planned 1970s-era Soviet program to give the Soviet Navy a true blue water aviation capability. Project Orel would have resulted in a program very similar to the aircraft carriers available to the U.S. Navy. The ship would have been about 75-80,000 tons displacement, with a nuclear power plant and carried about 70 aircraft launched via steam catapults – the first Soviet aircraft carrier that would be able to deploy fixed-wing aircraft.
Beyond this core capability, the Orel carrier was designed with a large offensive capability with the ship mounts including 24 vertical launch tubes for anti-ship cruise missiles. In the USSR it was actually classified as the "large cruiser with aircraft armament".
Anyway, the carrier needed appropriate aircraft, and in order to develop a the aircraft major design bureaus were asked to submit ideas and proposals in 1959. OKB Yakovlev and MiG responded. While Yakovlev concentrated on the Yak-36 VTOL design that could also be deployed aboard of smaller ships without catapult and arrester equipment, Mikoyan-Gurevich looked at navalized variants of existing or projected aircraft.
While land-based fighters went through a remarkable performance improvement during the 60ies, OKB MiG considered a robust aircraft with proven systems and – foremost – two engines to be the best start for the Soviet Union’s first naval fighter. “Learning by doing”, the gathered experience would then be used in a dedicated new design that would be ready in the mid 70ies when Project 1153 was ready for service, too.
Internally designated “I-SK” or “SK-01” (Samolyot Korabelniy = carrier-borne aircraft), the naval fighter was based on the MiG-19 (NATO: Farmer), which had been in production in the USSR since 1954.
Faster and more modern types like the MiG-21 were rejected for a naval conversion because of their poor take-off performance, uncertain aerodynamics in the naval environment and lack of ruggedness. The MiG-19 also offered the benefit of relatively compact dimensions, as well as a structure that would carry the desired two engines.
Several innovations had to be addresses:
- A new wing for improved low speed handling
- Improvement of the landing gear and internal structures for carrier operations
- Development of a wing folding mechanism
- Integration of arrester hook and catapult launch devices into the structure
- Protection of structure, engine and equipment from the aggressive naval environment
- Improvement of the pilot’s field of view for carrier landings
- Improved avionics, esp. for navigation
Work on the SK-01 started in 1960, and by 1962 a heavily redesigned MiG-19 was ready as a mock-up for inspection and further approval. The “new” aircraft shared the outlines with the land-based MiG-19, but the nose section was completely new and shared a certain similarity to the experimental “Aircraft SN”, a MiG-17 derivative with side air intakes and a solid nose that carried a. Unlike the latter, the cockpit had been moved forward, which offered, together with an enlarged canopy and a short nose, an excellent field of view for the pilot.
On the SK-01 the air intakes with short splitter plates were re-located to the fuselage flanks underneath the cockpit. In order to avoid gun smoke ingestion problems (and the lack of space in the nose for any equipment except for a small SRD-3 Grad gun ranging radar, coupled with an ASP-5N computing gun-sight), the SK-01’s internal armament, a pair of NR-30 cannon, was placed in the wing roots.
The wing itself was another major modification, it featured a reduced sweep of only 33° at ¼ chord angle (compared to the MiG-19’s original 55°). Four wing hardpoints, outside of the landing gear wells, could carry a modest ordnance payload, including rocket and gun pods, unguided missiles, iron bombs and up to four Vympel K-13 AAMs.
Outside of these pylons, the wings featured a folding mechanism that allowed the wing span to be reduced from 10 m to 6.5 m for stowage. The fin remained unchanged, but the stabilizers had a reduced sweep, too.
The single ventral fin of the MiG-19 gave way to a fairing for a massive, semi-retractable arrester hook, flanked by a pair of smaller fins. The landing gear was beefed up, too, with a stronger suspension. Catapult launch from deck was to be realized through expandable cables that were attached onto massive hooks under the fuselage.
The SK-01 received a “thumbs up” in March 1962 and three prototypes, powered by special Sorokin R3M-28 engines, derivatives of the MiG-19's RB-9 that were adapted to the naval environment, were created and tested until 1965, when the type – now designated MiG-SK – went through State Acceptance Trials, including simulated landing tests on an “unsinkalble carrier” dummy, a modified part of the runway at Air Base at the Western coast of the Caspian Sea. Not only flight tests were conducted at Kaspiysk, but also different layouts for landing cables were tested and optimized as well. Furthermore, on a special platform at the coast, an experimental steam catapult went through trials, even though no aircraft starts were made from it – but weights hauled out into the sea.
Anyway, the flight tests and the landing performance on the simulated carrier deck were successful, and while the MiG-SK (the machine differed from the MiG-19 so much that it was not recognized as an official MiG-19 variant) was not an outstanding combat aircraft, rather a technology carrier with field use capabilities.
The MiG-SK’s performance was good enough to earn OKB MiG an initial production run of 20 aircraft, primarily intended for training and development units, since the whole infrastructure and procedures for naval aviation from a carrier had to be developed from scratch. These machines were built at slow pace until 1968 and trials were carried out in the vicinity of the Black Sea and the Caspian Sea.
The MiG-SK successfully remained hidden from the public, since the Soviet Navy did not want to give away its plans for a CTOL carrier. Spy flights of balloons and aircraft recognized the MiG-SK, but the type was mistaken as MiG-17 fighters. Consequently, no NATO codename was ever allocated.
Alas, the future of the Soviet, carrier-borne fixed wing aircraft was not bright: Laid down in in 1970, the Kiev-class aircraft carriers (also known as Project 1143 or as the Krechyet (Gyrfalcon) class) were the first class of fixed-wing aircraft carriers to be built in the Soviet Union, and they entered service, together with the Yak-38 (Forger) VTOL fighter, in 1973. This weapon system already offered a combat performance similar to the MiG-SK, and the VTOL concept rendered the need for catapult launch and deck landing capability obsolete.
OKB MiG still tried to lobby for a CTOL aircraft (in the meantime, the swing-wing MiG-23 was on the drawing board, as well as a projected, navalized multi-purpose derivative, the MiG-23K), but to no avail.
Furthermore, carrier Project 1153 was cancelled in October 1978 as being too expensive, and a program for a smaller ship called Project 11435, more V/STOL-aircraft-oriented, was developed instead; in its initial stage, a version of 65,000 tons and 52 aircraft was proposed, but eventually an even smaller ship was built in the form of the Kuznetsov-class aircraft carriers in 1985, outfitted with a 12-degree ski-jump bow flight deck instead of using complex aircraft catapults. This CTOL carrier was finally equipped with navalized Su-33, MiG-29 and Su-25 aircraft – and the MiG-SK paved the early way to these shipboard fighters, especially the MiG-29K.

The kit and its assembly:
This kitbash creation was spawned by thoughts concerning the Soviet Naval Aviation and its lack of CTOL aircraft carriers until the 1980ies and kicked-off by a CG rendition of a navalized MiG-17 from fellow member SPINNERS at whatifmodelers.com, posted a couple of months ago. I liked this idea, and at first I wanted to convert a MiG-17 with a solid nose as a dedicated carrier aircraft. But the more I thought about it and did historic research, the less probable this concept appeared to me: the MiG-17 was simply too old to match Soviet plans for a carrier ship, at least with the real world as reference.
A plausible alternative was the MiG-19, esp. with its twin-engine layout, even though the highly swept wings and the associated high start and landing speeds would be rather inappropriate for a shipborne fighter. Anyway, a MiG-21 was even less suitable, and I eventually took the Farmer as conversion basis, since it would also fit into the historic time frame between the late 60ies and the mid-70ies.
In this case, the basis is a Plastyk MiG-19 kit, one of the many Eastern European re-incarnations of the vintage KP kit. This cheap re-issue became a positive surprise, because any former raised panel and rivet details have disappeared and were replaced with sound, recessed engravings. The kit is still a bit clumsy, the walls are very thick (esp. the canopy – maybe 2mm!), but IMHO it’s a considerable improvement with acceptable fit, even though there are some sink holes and some nasty surprises (in my case, for instance, the stabilizer fins would not match with the rear fuselage at all, and you basically need putty everywhere).
Not much from the Plastyk kit was taken over, though: only the fuselage’s rear two-thirds were used, some landing gear parts as well as fin and the horizontal stabilizers. The latter were heavily modified and reduced in sweep in order to match new wings from a Hobby Boss MiG-15 (the parts were cut into three pieces each and then set back together again).
Furthermore, the complete front section from a Novo Supermarine Attacker was transplanted, because its short nose and the high cockpit are perfect parts for a carrier aircraft. The Attacker’s front end, including the air intakes, fits almost perfectly onto the round MiG-19 forward fuselage, only little body work was necessary. A complete cockpit tub and a new seat were implanted, as well as a front landing gear well and walls inside of the (otherwise empty) air intakes. The jet exhausts were drilled open, too, and afterburner dummies added. Simple jobs.
On the other side, the wings were trickier than expected. The MiG-19 kit comes with voluminous and massive wing root fairings, probably aerodynamic bodies for some area-ruling. I decided to keep them, but this caused some unexpected troubles…
The MiG-15 wings’ position, considerably further back due to the reduced sweep angle, was deduced from the relative MiG-19’s landing gear position. A lot of sculpting and body work followed, and after the wings were finally in place I recognized that the aforementioned, thick wing root fairings had reduced the wing sweep – basically not a bad thing, but with the inconvenient side effect that the original wing MiG-15 fences were not parallel to the fuselage anymore, looking rather awkward! What to do? Grrrr…. I could not leave it that way, so I scraped them away and replaced with them with four scratched substitutes (from styrene profiles), moving the outer pair towards the wing folding mechanism.
Under the wings, four new pylons were added (two from an IAI Kfir, two from a Su-22) and the ordnance gathered from the scrap box – bombs and rocket pods formerly belonged to a Kangnam/Revell Yak-38.
The landing gear was raised by ~2mm for a higher stance on the ground. The original, thick central fin was reduced in length, so that it could become a plausible attachment point for an arrester hook (also from the spares box), and a pair of splayed stabilizer fins was added as a compensation. Finally, some of the OOB air scoops were placed all round the hull and some pitots, antennae and a gun camera fairing added.
Painting and markings:
This whif was to look naval at first sight, so I referred to the early Yak-38 VTOL aircraft and their rather minimalistic paint scheme in an overall dull blue. The green underside, seen on many service aircraft, was AFAIK a (later) protective coating – an obsolete detail for a CTOL aircraft.
Hence, all upper surfaces and the fuselage were painted in a uniform “Field Blue” (Tamiya XF-50). It’s a bit dark, but I have used this unique, petrol blue tone many moons ago on a real world Kangnam Forger where it looks pretty good, and in this case the surface was furthermore shaded with Humbrol 96 and 126 after a black in wash.
For some contrast I painted the undersides of the wings and stabilizers as well as a fuselage section between the wings in a pale grey (Humbrol 167), seen on one of the Yak-38 prototypes. Not very obvious, but at least the aircraft did not end up in a boring, uniform color.
The interior was painted in blue-gray (PRU Blue, shaded with Humbrol 87) while the landing gear wells became Aluminum (Humbrol 56). The wheel discs became bright green, just in order to keep in style and as a colorful contrast, and some di-electric panels and covers became very light grey or bright green. For some color contrast, the anti-flutter weight tips on the stabilizers as well as the pylons’ front ends were painted bright red.
The markings/decals reflect the early Soviet Navy style, with simple Red Stars, large yellow tactical codes and some high contrast warning stencils, taken from the remains of a Yak-38 sheet (American Revell re-release of the Kangnam kit).
Finally, after some soot stains with graphite around the gun muzzles and the air bleed doors, the kit was sealed with a coat of semi-matt acrylic varnish and some matt accents (anti-glare panel, radomes).
A simple idea that turned out to be more complex than expected, due to the wing fence troubles. But I am happy that the Attacker nose could be so easily transplanted, it changes the MiG-19’s look considerably, as well as the wings with (much) less sweep angle.
The aircraft looks familiar, but you only recognize at second glance that it is more than just a MiG-19 with a solid nose. The thing looks pretty retro, reminds me a bit of the Supermarine Scimitar (dunno?), and IMHO it appears more Chinese than Soviet (maybe because the layout reminds a lot of the Q-5 fighter bomber)? It could even, with appropriate markings, be a Luft ’46 design?

Some Background:
Antanas Gustaitis (March 26, 1898 – October 16, 1941) was an officer in the Lithuanian Armed Forces who modernized the Lithuanian Air Force, which at that time was part of the Lithuanian Army. He was the architect or aeronautical engineer who undertook the task to design and construct several military aircraft before WWII broke out.
Gustaitis was born in the village of Obelinė, in Javaravas county, in the Marijampolė district. He attended high school in Yaroslavl, and from there studied at the Institute of Engineering and School of Artillery in Petrograd. After joining the Lithuanian Army in 1919, he graduated from the School of Military Aviation as a Junior Lieutenant in 1920. Later that year, he saw action in the Polish-Lithuanian War. By 1922 he began to train pilots, and later became the head of the training squadron. He also oversaw the construction of aircraft for Lithuania in Italy and Czechoslovakia. Gustaitis was one of the founding members of the Aero Club of Lithuania, and later its Vice-President. He did much to promote aviation among the young people in Lithuania, especially concerning the sport of gliding. He also won the Lithuanian Chess Championship in 1922.
Between 1925 and 1928, Gustaitis studied aeronautical engineering in Paris. After his graduation he returned to Lithuania and was promoted to deputy Commander-in-Chief of Military Aviation and made chief of the Aviation Workshop (Karo Aviacijos Tiekimo Skyrius) in Kaunas. During this time, he reorganized the workshop and expanded its capability to repair aircraft as well. The aircraft he designed were named ANBO, an acronym for "Antanas Nori Būti Ore", which literally means “Antanas wants to be in the air” in Lithuanian.
Between 1925 and 1939, the ANBO design bureau developed, built and flew several trainers, reconnaissance and even fighter aircraft for the Lithuanian air force. The last projects, the ANBO VIII, a light single-engine reconnaissance bomber, and the ANBO IX, a single-seat fighter, were the most ambitious.
The ANBO IX started in 1935 as a light low-wing design with spatted, fixed landing gear and an open cockpit, powered by a British Bristol Mercury 830 hp (619 kW) 9-cylinder radial engine – a very clean all-metal design, outwardly not unlike the contemporary Japanese Nakajima Ki-27 or the Dutch Fokker D.XXI, but a much more modern construction.
A first prototype had been completed in summer 1936 and it flew for the first time on 1st of August, with good flight characteristics, but Gustaitis was not satisfied with the aircraft anymore. More powerful and aerodynamically more efficient engines had become available, and a retractable landing gear would improve the performance of the ANBO IX even more, so that the aircraft was heavily modified during the rest of the year.
The large Mercury was replaced with a Pratt & Whitney R-1535 Twin Wasp Junior, a two-row 14-cylinder radial engine with 825 hp and a much smaller frontal area that allowed the ANBO IX’s cowling to be wrapped much tighter around the engine than the Mercury’s former Townend ring, leading to a very aerodynamic overall shape. The oil cooler, formerly mounted starboard flank in front of the cockpit, was moved into a mutual fairing with the carburetor intake under the fuselage behind the engine.
The wings had to be modified to accommodate a retractable main landing gear: to make space for suitable wells, the inner wing section in front of the main spar was deepened, resulting in a kinked leading edge of the wing. The landing gear retracted inwards and was initially completely covered. The tail remained fixed, though, even though the former simple tailskid was replaced with a pressurized rubber wheel for better handling on paved runways.
These measures alone improved the ANBO IX’s top speed by 25 mph (40 km/h), and to improve the pilot’s working conditions the originally open cockpit with just a windscreen and a small headrest fairing was covered with a fully closed clear canopy and an enlarged aerodynamic spinal fairing that ended at the fin’s base. This additional space was used to introduce another contemporary novel feature on board: a radio set.
Together with some other refinements on a second prototype (e. g. a smaller diameter of the front fuselage section, an even more streamlined cowling that now also covered two synchronized machine guns above the engine and a recontoured wing/fuselage intersection), which flew in September 1937, top speed rose by another 6 mph (10 km/h) from 460 km/h (285 mph) of the original aircraft to a competitive 510 km/h (317 mph) that put the ANBO IX on a par with many other contemporary European fighter aircraft.
In this form the ANBO IX was cleared for production in early 1938, even though the desired R-1535 Twin Wasp Junior was not cleared for export or license production. With the Manfréd Weiss WM K.14 engine from Hungary, a derivative of the French Gnôme-Rhône 14 K with 900 hp, a similar, even slightly more powerful replacement could be quickly found, even though the adaptation of the airframe to the different powerplant delayed production by four months. Beyond a new engine mount, the machine guns in the fuselage and its synchronization gearbox had to be deleted, but the weapons could be moved into the outer wings, so that a total of four machine guns as main armament was retained. Additionally, a single ventral hardpoint was added that could either carry a single bomb with its respective shackles or – more frequently – a drop tank that extended the fighter’s rather limited range.
The Lithuanian air force ordered fifty of these machines, primarily to replace its Fiat CR.20 biplane fighters, and several regional export customers like Finland, Estonia and Bulgaria showed interest in the modern ANBO IX, too. Due to the complex all-metal airframe and limited workshop capacities, however, production started only slowly.
The first batch of six ANBO IXs arrived at Lithuanian frontline units in November 1939, more were in the ANBO workshops in Kaunas at that time in various stages of assembly. In 1940, the Lithuanian Air Force consisted of eight Air Squadrons, including reconnaissance, fighter, bomber and training units. However, only the 5th fighter squadron had by the time enough ANBO IXs and trained pilots to be fully operational with the new type. Air Force bases had been established in the cities and towns of Kaunas/Žagariškės, Šiauliai /Zokniai (Zokniai airfield), Panevėžys /Pajuostis. In the summertime, airports in the cities of Palanga and Rukla were also used. A total of 117 aircraft and 230 pilots and observers were listed in the books at that time, but less than ten of them were modern ANBO IX fighters, and probably only half of them were actually operational.
Following the Soviet occupation of Lithuania, however, the Lithuanian Air Force was formally disbanded on October 23, 1940. Part of Lithuanian Air Force (77 senior officers, 72 junior officers, 59 privates, 20 aircraft) was reorganized into Red Army's 29th Territorial Rifle Corps Aviation, also referred to as National Squadron (Tautinė eskadrilė). Other planes and equipment were taken over by Red Army's Air Force Bases No. 13 and 213. About third of Tautinė eskadrilė's personnel latter suffered repressions by Soviet authorities, significant share joined June uprising, after the start of German invasion into Soviet Union several pilots of Tautinė eskadrilė and fewer than six planes withdrew with the Soviet army.

The kit and its assembly:
This small aircraft model is the result of a spontaneous kitbashing flash, when I dug through the sprue piles and the spares box. It started with a leftover fuselage from a Mistercraft PZL P-7 fighter, and further searches revealed the wings from a PM Model Fokker D.XXI and the sawn-off wings from a Hobby Boss MS.406. The sprue stash came up with other useful parts like small stabilizers and a landing gear – and it turned out to be the rest of the MS.406, which had originally been butchered to be mated with the P-7 wings to become my fictional Polish RWD-24 fighter prototype. So, as a serious recycling project, I decided to accept the challenge and use the remains of the P-7 and the MS.406 to create a “counterpart” to the RWD-24, and it became the fictional ANBO IX.
While the ingredients for a basic airframe were now available, some parts were still missing. Most important: an engine. One option was an early Merlin, left over from a Spitfire, but due to the circular P-7 fuselage I preferred a radial engine. With the cowling from a Japanese Mitsubishi Ha-102 two-row radial (from an Airfix Ki-46 “Dinah”) I found a suitable and very streamlined donor, which received a small three-blade propeller with a scratched spinner on a metal axis inside.
The cockpit and the canopy caused more headaches, because the P-7 has an open cockpit with a rather wide opening. For a fighter with a retractable landing gear this would hardly work anymore and finding a solution as well as a suitable donor piece took a while. I initially wanted to use a kind of bubble canopy (with struts, so that it would not look too modern), but eventually rejected this because the proportions would have looked odd – and the overall style would have been too modern.
So I switched to an early Spitfire canopy, which had a good size for the small aircraft, even though it called for a spinal fairing – the latter became the half from a drop tank (IIRC from an Airfix P-61?).
Lots of PSR was necessary everywhere to blend the disparate parts together. The cockpit opening had to be partly filled and reshaped, blending both canopy and spine into the hull took several layers.
The area in front of the cockpit (originally holding the P-7’s shoulder-mounted wings) had to be re-sculpted and blended into the Ki-46 cowling.
The ventral area between the wings had also to be fully sculpted with putty, and huge gaps along the wing roots on the wings’ upper surfaces had to be filled and formed, too. No wonder that many surface details disappeared along the way… Nevertheless, the effort was worthwhile, because the resulting airframe, esp. the sleek fuselage, looks very aerodynamic, almost like a Thirties air speed record contender?
Painting and markings:
This is where the real trouble came to play. It took a while to find a suitable/authentic paint scheme for a pre-WWII Lithuanian aircraft, and I took inspiration from mid-Thirties Letov S.20 biplane fighters and the real ANBO VIII light bomber prototype. Apparently, a two-tone camouflage in two shades of green were an option, even though the tones appear debatable. The only real-life reference was a b/w picture of an S.20, and it showed a good contrast between the greens, so that my first choice were Humbrol 120 (FS 34227) and 172 (Satin Dark Green). However: 120 turned out to be much too pale, and the 172 had a somewhat grainy consistency. Leaving a horrible finish on the already less-than-perfect PSR mess of the model.
With a heavy heart I eventually decided to remove the initial coat of enamel paint with a two-day bath in foamed oven cleaner, which did the job but also worked on the putty. Disaster struck when one wing came loose while cleaning the model, and the canopy came off, too…
Repairs were possible, but did not improve the model’s surface finish – but I eventually pulled a second coat of paint through, this time with slightly different green tones: a mix of Humbrol 80 (Grass Green) and Revell 360 (fern Green), resulting in a rich but rather yellow-ish tone, and Humbrol 245 (RLM 75, Graugrün), as a subdued contrast. The result, though, reminded a lot of Finnish WWII aircraft, so that I gave the aircraft an NMF cowling (again inspired by the ANBO VIII prototype) and a very light grey (Modelmaster 2077, RLM 63) underside with a low waterline. This gave the model a somewhat Italian touch?
The national markings came from two different Blue Rider decal sheets for modern Lithuanian aircraft, the tactical code and the knight helmet as squadron emblem came from a French Dewoitine D.520 (PrintScale sheet).
After a black ink washing the kit received light panel post-shading to virtually restore some of the missing surface details, some weathering with Tamiya Smoke and silver was done and the model received a final overall coat of matt acrylic varnish.
Well, I am not happy with the outcome – mostly because of the painting mishaps and the resulting collateral damage overall. However, the kitbashed aircraft looks pretty conclusive and plays the role of one of the many European pre-WWII monoplane fighters with modern features like a retractable landing gear and a closed canopy well, it’s a very subtle result.
Some background:
Instead of a story compiled/edited by myself, a very good “real” source: an article about the “American Spirit” project from 1996, scanned from a magazine and posted elsewhere:
This and some more information, including a drawing of the (apparently never) finished aircraft and a photo of the semi-finished airframe on airliners.net were the basis for my build.
The kit and its assembly:
This is my third and last entry to the “Racing” group build at whatifmodelers.com that ended in Feb. 2019. It is nothing less than the attempt to re-create the potentially fastest piston engine aircraft in the world as a model, based on the sparse information I was able to gather (see above). The aircraft’s design is quite odd, and it is worth reading the design background in the article, because it was a true “garage build” with the intention to use as many existing components in order to save costs and development time.
This was, more or less, mirrored during the building process, and like the real “American Spirit” the model consists at its core of a Matchbox T-2 “Buckeye” jet trainer! The T-2 fuselage lost its nose section, the ventral engine bay and the original cockpit fairing. This left a lot of fuselage surface to be re-constructed. The fin was clipped, too, just like in real life. At the fin’s base I added a cockpit opening and implanted a cockpit tub, taken from a Revell G.91. A new bucket seat (probably from an Academy Fw 190) was installed, and a new, tight canopy – I think it originally came from a Revell Go 229, but it was trimmed down considerably to match the T-2’s fuselage lines. The canopy was blended into the fin root with massive 2C putty sculpting, and the area in front of the windscreen was created with 2C putty, too. Both a tedious PSR process.
Once the upper fuselage shape was finished I started searching for a cowling and a matching propeller. After several attempts with bigger engines (e. g. from a Super Constellation) I eventually settled upon a rather narrow (but bleak) cowling from an Pioneer2/Airfix Hawker Sea Fury, which turned out to have just the right diameter for the re-constructed T-2 fuselage and matched the “American Spirit” drawing’s well.
It also had at the front end the right diameter for the propeller: it comes, just like in real life, from a C-130 Hercules, even though I used a late variant with six blades, a resin aftermarket piece, taken from an Attack Squadron engine nacelle set. Unfortunately, the spinners were molded onto the engines, so that I had to cut my donor part away. Three of the six propeller blade attachment points were faired over. While the original “American Spirit” carried clipped blades from an Electra airliner, I used parts from a P-3 Orion – the come very close in shape and size, and were easy to install. Finally, the propeller received a metal axis and a matching styrene tube adapter in the Sea Fury cowling.
Once the engine was in place, the cowling was filled with as much lead as possible, since the model would be built with an extended landing gear.
However, a large ventral section was still missing, and it was created with a leftover underwater section from a model ship hull, and lots of more putty, of course. A small tail bumper was added under the fin.
Once the fuselage was more or less finished, I turned my attention to the wings and stabilizers. The latter were supposed to be “un-swept F-86H stabilizers”, but unfortunately I could not find visual evidence of what this would have looked like. I tried some donor parts, including stabilizers from an F-86A and D, as well as from a MiG-15, and eventually decided to use individual parts, because nothing looked convincing to me, either swept or straight. Actually the MiG-15 parts looked the best, but they were too small, so I used the wings from an 1:144 Panavia Tornado (Dragon) and tailored them into a sweep angle similar to the MiG-15 parts, but with more depth and span. Not certain how “realistic” this is, but it looks good and compliments the swept T-2 fin well.
The T-2 wings saw only minor modifications: the wing tip tanks were cut off and the tips as well as the flaps faired over, since the “American Spirit” did not feature the latter anymore. The small LERXs were cut away, too, and instead I added small air intakes – the “American Spirit” probably did not feature them, but I wondered where the aircraft’s engine would feed its carburetor or an oil cooler? The respective gaps on the fuselage flanks were filled accordingly.
Some more work waited on the fuselage, too. The aircraft’s drawing showed shallow openings on the forward fuselage’s flanks, but their function was not clear – I assume that the exhausts from the 18 cylinder engine were collected there, 9 on each side, so I carved the openings into the massive plastic and putty fuselage with a mini drill tool and added exhaust stubs as well as deflector plates.
Another issue was the well for the front landing gear – this came, together with the complete front leg, from an Italeri F-100, just like in real life. The good thing about the Italeri kit is that it comes with a separate well tub, which made the installation quite easy. I just cut a square section out of the lower fuselage behind the engine and the landing gear well snuggly fell into place, with only little PSR effort. And, to my surprise, the end result seems to be a very good match to the real life design – even though I was not able to confirm this with picture material.
The main landing gear was taken OOB from the Matchbox T-2 – and it is really a weird sight, since the T-2’s track is very wide while the wheelbase is unusually short. But the source article indicates that this must have been the designers’ plans!
Painting and markings:
While the model’s hardware came quite close to the real thing, the livery of the “American Spirit” was totally open, so I created my own. I felt that two design directions would be appropriate: either a relatively dry and clean design, e. g. in overall silver or white with a little trim, or something patriotic, reflecting the aircraft’s name.
I eventually settled for the latter, and considered several approaches in white, red and blue, and eventually settled for one of my first ideas, a kind of “flying American flag” in an asymmetrical design, somewhat inspired by a Bicentennial F-106A from 1976: this machine carried a white fuselage with some red trim stripes and a blue nose section that featured lots of tiny white stars. I took this layout a little further and gave the “American Spirit” a dark blue engine cowling and front fuselage section, as well as a single blue wing. From that, wide red and white stripes stream backwards across the other wing, the fuselage and the tail. The design was mirrored on the undersides.
The stripes were painted with a wide brush with Humbrol 19 and 22, after the kit had been primed with white and had received an overall white basic coat with acrylic paint from the rattle can, too. The blue section was painted with Revell 350 (RAL 5013/Lufthansa Blue). I tried to add some “wavy flag texture” effect to the basic paints with slightly different tones, added wet-in-wet to the basic paints, but the visual effect turned out to be minimal, so I left it like that.
The stars are all individual waterslide decals, coming from an 1:87 Allied WWII markings sheet from TL Modellbau. The big white stars that are the background for the starting numbers on top and below the blue wing come from an 1:72 F4U. The red and blue starting numbers themselves were taken from a TL Modellbau sheet for firefighting vehicles: they are actually parts of German emergency telephone numbers…
Some stencils and leading edges on all wings, created with generic silver decal material, completed the outside, and finally I painted some fake panel lines onto the hull with a soft pencil. The T-2 air brakes, which were retained for the “American Spirit”, were re-created with fine black decal lines. Similar material in silver was used to simulate panel lines for the cooling air outlet flaps on the cowling. Unfortunately, the T-2 kit itself did not come with much surface detail, and any leftover rest (like the air brakes) disappeared during the extensive PSR sessions and under the primer and paint coats. Finally, the kit was sealed with a coat of semi-gloss acrylic varnish (Italeri).
A massive scratch-build. While challenging the work on this model was fun because it followed in its creation a similar process as the real “American Spirit”, which was, AFAIK, sold and never completed. In the end, I am positively surprised how close the overall outlines seem to come to the real (and odd-looking) aircraft, even though the garish livery is purely speculative, so that this model is, despite its roots in the real world and the attempt to stay true to the original, a fictional/whif piece. The finish is a bit rough, though, but that’s probably the price to pay when you create things from scratch.

Some background:
After the Ukrainian independence in 1991, the Ukrainian Air Force (Повітряні Сили України, Povitryani Syly Ukrayiny) was established on March 17, 1992, in accordance with a Directive of the General Staff Chief of the Armed Forces. When the Soviet Union dissolved in 1991, many aircraft were left on Ukrainian territory, including a wide range of fighters and attack aircraft, helicopters and even strategic bombers, and these became the initial equipment. Ever since, the Ukrainian air force has been downsizing and upgrading its forces, but for many years the main inventory still consisted of Soviet-made aircraft.
Following the 2014 Ukrainian Revolution and subsequent March 2014 Russian annexation of the Crimea peninsula and the following violence and insurgency in east Ukraine, the Ukrainian government tried to increase its defense spending and capabilities. Returning equipment (of Russian origin, though) to service was a key part of the spending drive, but in parallel attempts were made to procure flying material from Western sources in order to become moer and more independent from the obtrusive neighbor. In April 2014 two MiG-29 aircraft were restored to flight on short notice and in August a decommissioned An-26 transport aircraft was restored to active service by a volunteer group. On 5 January 2015 the air force received another 4 restored airplanes, two MiG-29s and two Su-27s, as well as two Mi-8 and Mi-2 helicopters. However, since these aircraft had already accumulated a considerable number of flying hours, this could only have been an interim solution and the Ukraine turned directly to NATO for material support.
This politically highly delicate help was eventually granted in the form of eight General Dynamics F-16 C (six) and D (two) multi-role fighters of early Block 40 standard, leased from the U.S.A. and diverted from active aircraft which were about to become surplus stock and mothballed, anyway.
The F-16 Fighting Falcon itself was a single-engine supersonic multirole fighter aircraft originally developed by General Dynamics for the United States Air Force (USAF). Designed as a light air superiority day fighter as a complement to the heavier F-15 Eagle interceptor, it evolved into a successful all-weather multirole aircraft. Over 4,600 aircraft were built since production was approved in 1976. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta.
Although no longer being purchased by the launch customer, the U.S. Air Force, improved versions are still being built for export customers – the F-16 has been procured to serve in the air forces of 25 other nations all around the world, making it one of the world's most numerous fixed-wing aircraft in military service.
The Fighting Falcon's key features include a frameless bubble canopy for better visibility, side-mounted control stick to ease control while maneuvering, an ejection seat reclined 30 degrees from vertical to reduce the effect of g-forces on the pilot, and the first use of a relaxed static stability/fly-by-wire flight control system which helps to make it an agile aircraft. The F-16 has an internal M61 Vulcan cannon and the advanced C/D version features a total of 11 locations for mounting weapons and other mission equipment.
The eight machines for the Ukraine arrived in June 2016 via direct transfer flights over the Atlantic and Western Europe. The former USAF machines were delivered “as is”, even though they had some state-of-the-art avionics replaced by less sensitive alternatives from older F-16 production blocks. Together with the fighters, an undisclosed number of AIM-9M Sidewinder and AIM-120 AMRAAM air-to-air missiles were delivered, but the leasing agreement did not include LANTIRN pods that would provide the F-16C/D with improved all-day/all-weather strike capability. Other equipment like ECM pods was also not included. Service, maintenance and logistics for the new type in Ukrainian service was, due to the small operational number, secured with the help of the Polish air force, which had been operating 48 F-16C/D+ Block 52 fighters since 2006 and had the required experience and facilities at its 31st Tactical Air Base in Poznań-Krzesiny.
Upon arrival, the aircraft were immediately re-painted in a striking digital camouflage and received non-consecutive tactical codes, apparently based on the airframe’s former U.S. serial numbers, using the last two digits. They were all allocated to the 40th Tactical Aviation Brigade, based at Vasylkiv air base, south of Kiev, where they replaced a number of outdated and partly grounded MiG-29 fighters. They were exclusively tasked with aerial defense of the Ukrainian capital city – also as a political sign that the machines were not intended for attack missions.
Since their introduction, the Ukrainian F-16s have been fulfilling QRA duties and airspace patrol, and the corresponding maintenance infrastructure has been gradually built up, so that F-16 operations became independent from Poland in 2019. With the worsening relationship to Russia, more military hardware of Western origin is expected to enter Ukrainian service. If the tight Ukrainian defense budget allows it, twenty more 2nd hand F-16s are to be delivered in 2021 to replace more Soviet fighter types (primarily the rest of the Ukrainian MiG-29 “Fulcrum” single and two seater fleet), and the procurement of LANTIRN pods to expand the type’s capabilities is under consideration and negotiations, too.

The kit and its assembly:
I am not a big F-16 fan, but in some cases it’s an unavoidable canvas – just like in this case here. This fictional aircraft model (or better: this model of a [yet] fictional F-16 operator) was spawned by two ideas. One was the simple question: what if the Ukraine had after the USSR’s dissolution chosen a stronger attachment to (old) Western forces after the dissolution of the USSSR? And/or: what if the Ukraine had started to procure non-Russian equipment, esp. aircraft? So, what would an Ukrainian F-16 might have looked like, in general but esp. after the Crimea annexation in 2014 when such a scenario had become even more possible?
The other source of inspiration was a picture of an Ukrainian Su-24 with grey digital camouflage, a scheme that was/is also worn by some Su-25s. When I stumbled upon an Authentic Decals sheet for this unique paint scheme that allows to apply the complex and delicate pattern through water-slide transfers, I thought that the relatively “flat” F-16 surface would be an ideal basis to try this stunt?
What sounded like a very simple livery whif on an OOB model turned into a construction nightmare. Originally, this project provided me with a purpose for a dubious Trumpeter F-16 kit that I had bought some years ago – dead cheap, but righteously so. This kit is cruel, the model even has no concrete variant specification and is apparently the re-boxing of a kit from an obscure Chinese company called “Income”. Effectively, the Trumpeter F-16 is a rip-off of Italeri’s quite nice F-16C/D kit – but the Income/Trumpeter clone comes with MUCH deeper engravings esp. on the fuselage that remind a lot of the dreaded Matchbox “trenches”. Everything is rather “soft” and toylike, the clear parts are poor and the (few) decals look like toy stickers (!!!). I’d call it crude, even the instructions are apparently poor scans or photocopies from the Italeri kit, including hints for detail painting with no corresponding reference what colors should be used at all… All that could have been overlooked, but after starting with the kit I could not commit myself to use it any further. It’s rare that I give up because of a kit’s basis!
Next idea to “save” the project’s idea of an Ukrainian F-16 was to dig out a surplus Intech F-16 from the pile, also bought long ago because it was cheap, as conversion fodder. This kit has also been re-released in infinite variations under the Mister-/Mastercraft label. Upon closer inspection this kit turned out to have massive flaws, too, but in different areas from the Trumpeter thing. For instance, the Intech kit’s wings are utterly thick, certainly 1mm thicker than the Trumpeter model’s parts. This does not sound much, but on the really thin F-16 wings and stabilizers this looks really awful! Furthermore, the clear parts had not been fully molded, so I’d have needed a replacement canopy, anyway. Again, I gave up on building…
…until I decided to make the best of this mess and combine the “best” parts from both gimp models, trying to mend the worst flaws to an acceptable level. This led to the glorious kitbashing that this model eventually became! From the Intech kit I took the acceptable fuselage, including cockpit interior, air intake and landing gear, as well as the fin and the weapon pylons. The Trumpeter kit donated its thinner wings and the stabilizers, as well as the much better open exhaust nozzle (there’s an optional closed one, too; the Intech kit only offers an open nozzle, without ANY surface detail at all, it’s just a blank pipe!).
Beyond these basic ingredients, some more donors became necessary: All clear parts from both Intech and Trumpeter kit turned out to be rubbish for various reasons. The decision to build an F-16D two-seater was dictated by the fact that I had a leftover canopy from an Italeri F-16 kit in the donor bank – luckily it fitted well to the Intech kit’s body. Two crewmen from the spares box populate the cockpit and hide the rather basic interior, which was not improved at all. Furthermore, the ordnance came from external sources, too. The characteristic drop tanks with their cut-off tails were also leftover parts from the Italeri F-16, all AAMs come from a Hasegawa weapon set.
Some PSR was necessary to blend the parts from different kits together – thankfully, almost all F-16 kits are constructed in a similar fashion, even though there are small detail differences. In this case, the wings had to be slightly modified to fit onto the Intech fuselage. However, even those parts from the original kit(s) that are supposed to fit, e.g. the fin or the alternative cockpit opening frames for the optional single- and two-seater canopies, do hardly match at all. Horrible.
I rather focused on the model’s exterior, and a personal addition to improve the overall look of the otherwise rather basic/poor model, I added some small blade antennae that were totally missing on either model. Another extra detail are the small static dischargers on the trailing edges, created with thin, heated sprue material. Only small details, but they improve IMHO the model’s look considerably.
Painting and markings:
Until today, I never dared to apply decal camouflage to a model, but I expected that the flat/smooth F-16 surface would make this stunt relatively easy. This application method would also make painting the model easy, since only a single, uniform color had to be laid down from above and below.
To my surprise, the painting instructions of the Authentic Decals sheet for a number of Ukrainian Su-25 (which all carry the same standardized pixel camouflage) indicated RAL tones – a little surprising, but: why not? Since no other authentic color references were available, I cross-checked the paint suggestions with real life pictures of Su-24s and -25s in this striking paint scheme, and the indicated tones appear very plausible.
The problem: not every RAL tone is available as a model paint, so I had to make guesstimates. This eventually led to Modelmaster 2133 (Fulcrum Grey) as a light grey overall basis (suggested: RAL 7030 Achatgrau/Agate Grey, a tone with a brownish hue) from above and Humbrol 47 (Sea Blue Gloss) for a pale blue underside. The recommendation for the belly is RAL 7001 (Silbergrau/Silver Grey, very close to FS 36375), and this appears plausible, too, even though real-life pictures suggest a more bluish tone. But for a more dramatic look and some color contrast to the upper side’s all-grey I deliberately settled upon the Humbrol color, and this looks IMHO good.
The other suggested grey tones that make up the pixel patterns are RAL 7040 (Fenstergrau/Window Grey), RAL 7037 (Staubgrau/Dust Grey) and RAL 7043 (Verkehrsgrau B/Traffic Grey).
The cockpit interior was painted in medium grey (FS 36231, Humbrol 140), the air intake and the landing gear in white (Humbrol 22). The exhaust nozzle was painted externally with individual Metallizer mixes (with blue and gold added), while the inside was painted with Burnt Steel Metallizer towards the afterburner section while the ceramic nozzle petals were painted in a pale, almost white grey with darker lines, applied wet-in-wet. This looks pretty good – but does not withstand a closer inspection, just like the rest of this Franken-bashed F-16 thing.
Applying the digital camouflage pattern went better than expected. The decals turned out to be very thin and delicate, though, with almost no excessive clear film outside of the printed areas, so that application had to be executed swiftly and with lots of water to slide them into place. Nothing for modelers who are faint at heart! Because the single pixel clouds partly follow the Su-25 outlines, the decals had partly to be tailored to the rather different F-16 shape, and due to the different proportions I also had to improvise with the material at hand – fortunately the Su-25 sheet offered enough material to cover the F-16! Some small areas lacked decal material and had to be filled through painting, though, with replacement model paints for the aforementioned darker RAL greys, namely Humbrol 246 (RLM 75) and a 2:1 mix of Humbrol 125 and 67. The lightest grey on the prints turned out to be very close to the Fulcrum Grey, so there’s unfortunately very little contrast, and this only became clear after the decals had already dried. However, I left it that way, because lightening the Fulcrum Grey up further would have been a quite messy affair, ending in a rather dirty look that I wanted to avoid, and it had called for an almost white tone.
Another challenge became the weathering process, since I normally apply a black ink wash and some post-panel shading to the finished and painted model before I add the decals to a model. Fearing that the ink might creep under the decals’ clear sections, I left that step out completely. The delicate static dischargers were another complicating factor. So, I decided to finish the upper camouflage with the light grey base and the decals cammo first. This made trimming down excess decal material easier. After that had been roughly finished, the dischargers were added and the underside was painted blue. On top of that came the “normal” decals with national markings, codes and stencils. The latter were mostly taken from a vintage Microscale F-16 sheet, the tactical code came from a Begemot Ka-27 sheet. Since the bort number on the air intake was not well visible frame every angle, I added a white 77 to the fin, too. Thereafter I added some panel lines with the help of thinned black ink and a soft pencil. This way the model appears pretty clean, and I think that’s fine since many recent Ukrainian aircraft I know from pictures look well-tended. Finally, the model was sealed with matt acrylic varnish overall.
A simple F-16 in alternative markings – that’s what this model was supposed to be. I did not expect that the building phase would become such a challenge, and I’d sincerely recommend to any modeler who wants to build a “serious” F-16 in 1:72 to stay away from the Trumpeter and the Intech/Mister-/Mastercraft kits. They might be cheap, but that does not outweigh their flaws and building troubles.
Beyond these technical issues, I like the look of this “Ukrainized” Viper, the digital camouflage looks very special and works well on the aircraft. The light grey base could have been lighter, though. In fact, the F-16 now looks like an exaggerated U.S. Aggressor on first sight, but with the Ukrainian markings the whole thing looks pretty different and conclusive - a “what if” in the best sense. 😉

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 Société Nationale des Chemins de Fer Luxembourgeois (Luxembourg National Railway Company, abbreviated CFL) is the national railway company of Luxembourg. The Luxembourg rail system comprises (only) 275 route-kilometres (170 miles), of which 140 kilometres (87 mi) is double track and 135 kilometres (84 mi) single track. Of the total track length of 617 kilometres (383 mi), 576 kilometres (358 mi) are electrified at 25 kV, 50 Hz AC.
Luxembourg borders Belgium, France and Germany. Correspondingly, there are cross-border services into these countries. Some are wholly run by CFL, whereas others are run by SNCF, NMBS/SNCB and DB. CFL passenger trains cover most of the network and are operated by EMUs and electric locomotives, typically with push-pull stock. Despite a high degree of electrification, the CFL also had a fleet of diesel locomotives for hauling freight trains and for general shunting purposes. CFL.
The CFLs first electric locomotive, introduced in 1958, was the Class 3600, the so-called “fer à repasser” (= “electric iron”), a group of twenty electric locomotives that were built to the design of the French BB 12000 class. These were primarily intended for freight trains but also capable of pulling light passenger trains with up to 120 km/h (75 mph). The Class 3600 was originally designed to be capable of pulling 750 ton trains along a grade of 10 ‰, but in service it proved more than capable, frequently pulling 1100 tons and then even 1400 ton trains without problems.
However, for fast and heavier passenger trains, especially those that crossed the borders to Northern France with the same 25 kV, 50 Hz alternating current system as Luxembourg as well as to Germany with its 15 kV, 16.7 Hz electrification, the CFL ordered twelve additional dual system locomotive. They were more powerful and faster than the Class 3600 and became the new Class 3800 – roughly comparable with the German E 310/BR 181 dual system locomotives that were operated in the same region. The Class 3800 machines were designed and built between 1959 and 1961 in the Netherlands by Werkspoor in Utrecht, with technical support from the German Siemens-Schuckert-Werke (SSW) for the electric systems. They were heavily influenced by the contemporary Co′Co′ multipurpose Series 1200 electric locomotives for the Netherlands Spoorwegen (NS), originally designed by Baldwin and sporting typical American styling with a brawny silhouette, stepped “Cab unit” style nose sections and doors at the locomotives’ front ends to allow direct access to a coupled wagon from the driver cabins.
Even though they were based on the NS Series 1200, the CFL Class 3800 units used a shortened main frame and newly developed bogies with a Bo′Bo’ arrangement. All in all, the Class 3800 was more than 20 tons lighter than its Dutch six-axle sibling and only shared a superficial similarity – under the hood, the locomotive was technically totally different from the NS’ Series 1200 (which was designed for the Dutch 1.5 kV DC system).
The locomotives drew their energy from the 15 kV / 16 2/3 Hz or 25 kV / 50 Hz catenary via two diamond pantographs with contact strips of different lengths for the different areas of application. The 3-core transformers were oil-cooled, to which the control unit with its 28 running steps was connected. The acceleration was designed to function in delayed mode, where the engineer chose the running step, and the control unit would initiate the chosen setting independently. For emergency operation manual control by hand crank was possible, too. The voltage reached the main transformer via an air-operated main switch. On the secondary side, the traction motors were controlled via thyristors using stepless phase angle control, a modern technology at the time, as were the comparatively light mixed current motors. Mechanical switching mechanisms were therefore no longer required, and the vehicle control technology also worked with modern electronics. To ensure a good frictional connection between rail and wheel, the power converters always regulated a slightly lower tractive force on the preceding wheel sets of each bogie. If, however, one or more wheelsets slipped, the drive control reduced the tractive effort for a short time.
The CFL Class 3800’s four traction motors collective output was 3,700 kW (5,000 hp). This gave the Class 3800 a tractive effort of 275 kN (62,000 lbf) and a theoretical top speed of 150 km/h (93 mph), even though this was in practice limited to 140 km/h (87 mph). A time-division multiplex push-pull and double-traction control system was installed, too, so that two of these locomotives could together handle heavier freight trains and exploit the locomotives’ good traction. All locomotives featured an indirect air brake, with automatically stronger braking action at high speeds; for shunting/switching service an additional direct brake was present, too. All units featured a separately excited rheostatic/regenerative brake, which was coupled to the air brake. The heat generated by the electric brakes was dissipated via roof exhausts, supported by a pair of cooling fans.
The safety equipment in the driver's cab featured a mechanical or electronic deadman's device, punctiform automatic train controls, and train radio equipment with GSM-R communication. For operations in Germany the units received a third front light and separate red taillights, as well as an “Indusi” inductive system for data transfer between the track and locomotive by magnets mounted beside the rails and on the locomotive. Later in their career, automatic door locking at 0 km/h was retrofitted, which had become a compulsory requirement for all locomotives in passenger service.
After a thorough test phase of the pre-production locomotives 3801 and 3802 in 1960, the first Class 3800 serial units went into service in 1961 and were, due to the characteristic design of their driver’s cabins and their bulky shape, quickly nicknamed “Bouledogue” (Bulldog). The initial two locomotives were delivered in a pale blue-grey livery, but they were soon repainted in the CFL’s standard burgundy/yellow corporate paint scheme, and all following Class 3800 locomotives from 3803 on were directly delivered in this guise.
Initially, the service spectrum of the Bouledogues comprised primarily fast passenger trains on the CFL’s domestic main routes to the North and to the East, with additional border-crossing express trains, including prestigious TEE connections, to Germany (e. g. to Trier and Cologne) and France (Paris via Reims). The 3800s supplemented the CFL’s fast Series 1600 diesel locomotives on these important international destinations once they had been fully electrified. Occasionally, they were also used for freight trains in the industrial Esch-sur-Alzette region and for fast freight trains on the electrified main routes, as well as for regional passenger traffic on push-pull trains. Heavier freight trains remained the working field of the CFL Class 3600, even though occasional ore trains were handled by Class 3800 locomotives in double traction, too.
Even though Werkspoor hoped for more CFL orders for this dual-system type, the twelve Series 3800 locomotives remained the sole specimen. Potential buyers like Belgium or the Netherlands also did not show much interest – even though the SNCB ordered several multi-system locomotives, including eight indigenous Class 16 locomotives, equipped to run in France, Netherlands and Germany, or the six Class 18 four-system machines derived from the French SNCF CC 40100 express passenger locomotives.
During the Nineties the CFL started to use more and more EMUs on the domestic passenger routes, so that the Class 3800s gradually took over more and more freight train duties, relieving the older Series 3600s and replacing diesel-powered locomotives (esp. the Class 1800) on electrified routes. Border-crossing passenger train services were furthermore limited to trains to Germany since long-distance passenger train services in France switched to the TGV train system with its separate high-speed lines. Freight trains to France were still frequent Class 3800 duties, though, and occasionally coal trains were pulled directly to the industrial Ruhr Area region in Western Germany.
After the Millennium the Class 3800s gradually lost their duties to the new CFL Class 4000 multi-system locomotives, a variant of the Bombardier TRAXX locos found working across Europe. On 31 December 2006 the last Class 3800 (3809) was retired. Their versatility, robustness and performance have, however, allowed some of these locomotives to exceed 45 years of service. Bouledogue “3803” reached more than 9,2 million kilometers (5.7 million miles), a remarkable performance.
Only two 3800s had to be written off during the type’s career: 3804 suffered a major transformer damage and was destroyed by the ensuing fire near Troisvierges in Northern Luxembourg and 3810 was involved in a freight train derailment south of Differdange, where it was damaged beyond repair and had to be broken up on site. A single Class 3800 locomotive (3811) survived the retirement and has been kept as a static exhibition piece at the CFL Dépot at Luxembourg, the rest was scrapped.

The model and its assembly:
My second attempt to create a functional H0 scale what-if locomotive – and after I “only” did a color variant with some cosmetic changes on the basis of a Märklin V160/BR 216 diesel locomotive, I wanted something more special and challenging. However, kitbashing model locomotives with a metal chassis that includes a functional motor, respective drivetrain/gearing and electronics is not as easy as gluing some plastic parts together. And finding “matching” donor parts for such a stunt is also not as easy as it may seem. But what would life be without attempts to widen its boundaries?
This time I wanted an electric locomotive. Inspiration (and occasion) somewhat struck when I stumbled upon a running/functional chassis of a Märklin E 10/BR 110 (#3039), just without light and naturally missing the whole upper hull. Due to its incompleteness, I got it for a reasonable price, though. With this basis I started to watch out for eventual (and affordable) donor parts for a new superstructure, and remembered the collectible, non-powered all-plastic locomotive models from Atlas/IXO.
The good thing about the Märklin 3039 chassis was that it was just a solid and flat piece of metal without integrated outer hull elements, headstock or side skirts, so that a new hull could (theoretically) be simply tailored to fit over this motorized platform. Finding something with the exact length would be impossible, so I settled upon an Atlas H0 scale Nederlands Spoorwegen Series 1200 locomotive model, which is markedly longer than the German BR 110, due to its six axles vs. the E 10/BR 110’s four. Another selling point: the NS 1200’s body is virtually blank in its middle section, ideal for shortening it to match the different chassis. Detail of the Atlas plastic models is also quite good, so there was the potential for something quite convincing.
Work started with the disassembly of the static Atlas NS Class 1200 model. It's all-styrene, just with a metal plate as a chassis. Against my expectations the model's hull was only held on the chassis by two tiny screws under the "noses", so that I did not have to use force to separate it. The body's walls were also relatively thin, good for the upcoming modifications. The model also featured two nice driver's stations, which could be removed easily, too. Unfortunately; they had to go to make enough room for the electronics of the Märklin 3039 all-metal chassis.
Dry-fitting the chassis under the Class 1200 hull revealed that the stunt would basically work - the chassis turned out to be only marginally too wide. I just had to grind a little of the chassis' front edges away to reduce pressure on the styrene body, and I had to bend the end sections of the chassis’ stabilizing side walls.
To make the Class 1200 hull fit over the shorter BR 110 chassis a section of about 3 cm had to be taken out of the body’s middle section. The Class 1200 lent itself to this measure because the body is rather bare and uniform along its mid-section, so that re-combining two shortened halves should not pose too many problems.
To make the hull sit properly on the chassis I added styrene profiles inside of it - easy to glue them into place, thanks to the material. At this time, the original fixed pantographs and some wiring on the roof had gone, brake hoses on the nose were removed to make space for the BR 110 couplers, and the clear windows were removed after a little fight (they were glued into their places, but thankfully each side has three separate parts instead of just one that would easily break). PSR on the seam between the hull halves followed, plus some grey primer to check the surface quality.
Even though the new body now had a proper position on the metal chassis, a solution had to be found to securely hold it in place. My solution: an adapter for a screw in the chassis’ underside, scratched. I found a small area next to the central direction switch where I could place a screw and a respective receiver that could attached to the body’s roof. A 3 mm hole was drilled into the chassis’ floor and a long Spax screw with a small diameter was mated with a hollow square styrene profile, roughly trimmed down in length to almost reach the roof internally. Then a big lump of 2C putty was put into the hull, and the styrene adapter pressed into it, so that it would held well in place. Fiddly, but it worked!
Unfortunately, the pantographs of the Atlas/IXO model were static and not flexible at all. One was displayed raised while the other one was retracted. Due to the raised pantograph’s stiffness the model might lose contact to or even damage the model railroad catenary, even when not pulling power through it – not a satisfactory condition. Since the chassis could be powered either from below or through the pantographs (the Märklin 3039 chassis offers an analogue switch underneath to change between power sources) I decided to pimp my build further and improve looks and functionality. I organized a pair of aftermarket diamond pantographs, made from metal, fully functional and held in place on the model’s roof with (very short and) small screws from the inside.
I was not certain if the screws were conductive, and I had to somehow connect them with the switch in the chassis. I eventually soldered thin wire to the pantographs’ bases, led them through additional small holes in the roof inside and soldered them to the switch input, with an insulating screw joint in-between to allow a later detachment/disassembly without damage to the body. There might have been more elegant solutions, but my limited resources and skills did not allow more. It works, though, and I am happy with it, since the cables won’t be visible from the outside. This layout allows to draw power through them, I just had to create a flexible and detachable connection internally. Some plugs, wire and soldering created a solution – rough (electronics is not my strength!), but it worked! Another investment of money, time and effort into this project, but I think that the new pantographs significantly improve the overall look and the functionality of this model.
Internally, the missing light bulbs were retrofitted with OEM parts. A late external addition were PE brass ladders for the shunting platforms and under the doors for the driver’s cabins. They were rather delicate, but the model would not see much handling or railroading action, anyway, and the improve the overall impression IMHO a lot. On the roof, some details like cooling fans and tailored conduits (from the Atlas Series 1200) were added, they partly obscure the seam all around the body.
Unfortunately, due to the necessary space for the chassis, its motor and the electronics, the driver stations’ interiors could not be re-mounted – but this is not too obvious, despite the clear windows.
Painting and markings:
Finding a suitable operator took some time – I wanted a European company, and the livery had to be rather simple and easy to create with my limited means at hand, so that a presentable finish could be achieved. Belgium was one candidate, but I eventually settled on the small country of Luxembourg after I saw the CFL’s Class 3600s in their all-over wine-red livery with discreet yellow cheatlines.
The overall basic red was, after a coat with grey primer, applied with a rattle can, and I guesstimated the tone with RAL 3005 (Weinrot), based on various pictures of CFL locomotives in different states of maintenance and weathering. Apparently, the fresh paint was pretty bright, while old paint gained a rather brownish/maroon hue. For some contrast, the roof was painted in dark grey (Humbrol 67; RAL 7024), based on the CFL’s Class 3600 design, and the pantographs’ bases were painted and dry-brushed with this tone, too, for a coherent look. The chassis with its bogies and wheels remained basically black, but it was turned matt, and the originally bare metal wheel discs were painted, too. The visible lower areas were thoroughly treated with dry-brushed red-brown and dark grey, simulating rust and dust while emphasizing many delicate details on the bogies at the same time.
The hull was slightly treated with dry-brushed/cloudy wine red, so that the red would look a bit weathered and not so uniform. The grey roof was treated similarly.
The yellow cheatlines were created with yellow (RAL 1003) decal stripes from TL Modellbau in 5 and 2mm width. Generic H0 scale sheets from the same company provided the yellow CFL logos and the serial numbers on the flanks, so that the colors matched well. Stencils and some other small markings were procured from Andreas Nothaft (Modellbahndecals.de).
After securing the decals with some acrylic varnish the model was weathered with watercolors and some dry-brushing, simulating brownish-grey dust and dirt from the overhead contact line that frequently collects on the roof and is then washed down by rain. Finally, the whole body was sealed with matt acrylic varnish from the rattle can – even though it turned out to be rather glossy. But it does not look wrong, so I stuck with this flaw.
Among the last steps was the re-mounting of the clear windows (which had OOB thin silver trim, which was retained) and head- and taillights were created with ClearFix and white and red clear window color.

Development studies at Grumman for jet-powered fighter aircraft began near the end of World War II as the first jet engines emerged. In a competition for a jet-powered night fighter for the United States Navy, on 3 April 1946 the Douglas F3D Skyknight was selected over Grumman's G-75, a two-seater powered by four Westinghouse J30s. The Navy's Bureau of Aeronautics (BuAer) also issued a contract to Grumman for two G-75 prototype aircraft on 11 April 1946, in case the Skyknight ran into problems.
However, Grumman soon realized that the G-75 was a dead end. But the company had been working on a completely different day fighter, the G-79, which offered a higher potential. In order to keep Grumman in the US Navy’s procurement loop, BuAer, in a bureaucratic maneuver, did not cancel the G-75 contract, but changed the wording to include prototypes of the entirely different G-79, too.
The G-79 project comprised a total of four different layouts and engine arrangements for a single seat fighter aircraft. G-79A and B were traditional tail sitters, but both featured mixed propulsion for an enhanced performance: G-79A was powered by an R-2800 radial engine and a Rolls Royce Derwent VI jet booster in the tail, fed by a pair of dorsal air intakes behind the cockpit. The G-79B was a similar aircraft, but its primary engine was a General Electric TG-100 turboprop in a more slender nose section. Even though both designs were big aircraft, initial calculations indicated a performance that would be superior to the Grumman F8F Bearcat, which had been designed as a thoroughbred interceptor.
The other two designs were pure jet fighters, both with a tricycle landing gear. G-79C had a layout reminiscent of the Gloster Meteor and was powered by two Derwent VI engines in bulky wing nacelles, and G-79D was finally an overall smaller and lighter aircraft, similar in its outlines to the early Vought F6U Pirate, and powered by a single Nene in the rear fuselage, fed by air intakes in the wing roots.
Since the operation of jet-powered aircraft from carriers was terra incognita for the US Navy, and early turbojets thirsty and slow to react to throttle input, BuAer decided to develop two of Grumman's G-79 designs into prototypes for real life evaluation: one of the conservative designs, as a kind of safe route, and one of the more modern jets.
From the mixed propulsion designs, the turboprop-powered G-79B was chosen (becoming the XF9F-1 'JetCat'), since it was expected to offer a higher performance and development potential than the radial-powered 'A'. From the pure jet designs the G-79D was chosen, because of its simplicity and compact size, and designated XF9F-2 'Panther'.
The first JetCat prototype made its maiden flight on 26 October 1947, but it was only a short airfield circuit since the TG-100 turpoprop failed to deliver full power and the jet booster had not been installed yet. The prototype Panther, piloted by test pilot Corky Meyer, first flew on 21 November 1947 without major problems.
In the wake of the two aircrafts' test program, several modifications and improvements were made. This included an equal armament of four 20mm guns (mounted in the outer, foldable wings on the JetCat and, respectively, in the Panther’s nose). Furthermore, both aircraft were soon armed with underwing HVAR air-to-ground rockets and bombs, and the JetCat even received an underfuselage pylon for the potential carriage of an airborne torpedo. Since there was insufficient space within the foldable wings and the fuselage in both aircraft for the thirsty jet’s fuel, permanently mounted wingtip fuel tanks were added on both aircraft, which incidentally improved the fighters' rate of roll. Both F9F types were cleared for flight from aircraft carriers in September 1949.
The F9F-1 was soon re-engined with an Allison T38 turboprop, which was much more reliable than the TF-100 (in the meantime re-designated XT31) and delivered a slightly higher power output. Another change was made for the booster: the bulky Derwent VI engine from the prototype stage was replaced by a much more compact Westinghouse J34 turbojet, which not only delivered slightly more thrust, it also used up much less internal space which was used for radio and navigation equipment, a life raft and a relocated oil tank. Due to a resulting CG shift towards the nose, the fuselage fuel cell layout had to be revised. As a consequence, the cockpit was moved 3’ backwards, slightly impairing the pilot’s field of view, but it was still superior to the contemporary Vought F4U.
Despite the engine improvements, though, the F9F-1 attained markedly less top speed than the F9F-2. On the other side, it had a better rate of climb and slow speed handling characteristics, could carry more ordnance and offered a considerably bigger range and extended loiter time. The F9F-2 was more agile, though, and more of the nimble dogfighter the US Navy was originally looking for. Its simplicity with just a single engine was appealing, too.
The Panther was eventually favored as the USN's first operational jet day fighter and put into production, but the F9F-1 showed much potential as a fast fighter bomber. Through pressure from the USMC, who was looking for a replacement for its F7F heavy Tigercat fighters, a production order for 50 JetCats was eventually placed, later augmented to 82 aircraft because the US Navy also recognized the type’s potential as a fast, ship-borne multi-role fighter. Further interest came in 1949 from Australia, when the country’s government was looking for a - possibly locally-built in license - replacement for the outdated Mustang Mk 23 and De Havilland Vampire then operated by the Royal Australian Air Force (RAAF). Both Grumman designs were potential contenders, rivalling with the domestic CAC CA-23 fighter development.
The Grumman Panther became the most widely used U.S. Navy jet fighter of the Korean War, flying 78,000 sorties and scoring the first air-to-air kill by the U.S. Navy in the war, the downing of a North Korean Yakovlev Yak-9 fighter. Being rugged aircraft, F9F-2s, -3s and -5s were able to sustain operations, even in the face of intense anti-aircraft fire. The pilots also appreciated the Panther’s air conditioned cockpit, which was a welcome change from the humid environment of piston-powered aircraft.
The F9F-1 did fare less glamorous. Compared with the prototypes, the T38 turboprop's power output could be enhanced on service aircraft, but not on a significant level. The aircraft's original, rather sluggish response to throttle input and its low-speed handling were improved through an eight-blade contraprop, which, as a side benefit, countered torque problems during starts and landings on carriers.
The JetCat’s mixed powerplant installation remained capricious, though, and the second engine and its fuel meant a permanent weight penalty. The aircraft's complexity turned out to be a real weak point during the type's deployment to front line airfields in the Korean War, overall readiness was – compared with conservative types like the F4U and also the F9F-2, low. Despite the turboprop improvements, the jet booster remained necessary for carrier starts and vital in order to take on the MiG-15 or post-war piston engine types of Soviet origin like the Lavochkin La-9 and -11 or the Yakowlev Yak-9.
Frequent encounters with these opponents over Korea confirmed that the F9F-1 was not a “naturally born” dogfighter, but rather fell into the escort fighter or attack aircraft class. In order to broaden the type's duty spectrum, a small number of USMC and USN F9F-1s was modified in field workshops with an APS-6 type radar equipment from F4U-4N night fighters. Similar to the Corsair, the radar dish was carried in a streamlined pod under the outer starboard wing. The guns received flame dampers, and these converted machines, re-designated F9F-1N, were used with mild success as night and all-weather fighters.
However, the JetCat remained unpopular among its flight and ground crews and, after its less-than-satisfactory performance against MiGs, quickly retired. After the end of the Korean War in July 1953, all machines were grounded and by 1954 all had been scrapped. However, the turboprop-powered fighter bomber lived on with the USMC, which ordered the Vought A3U SeaScorpion as successor.

The kit and its assembly:
This is another submission to the Cold War GB at whatifmodelers in early 2018, and rather a spontaneous idea. It was actually spawned after I finished my fictional Gudkov Gu-1 mixed propulsion fighter - while building (using the engine front from an F6F Hellcat) I had the impression that it could also have ended up as a post-war USN fighter design.
A couple of days later, while browsing literature for inspiration, I came across Grumman's G-79 series of designs that eventually led to the F9F Panther - and I was amazed that the 'A' design almost looked like my kitbashed Soviet fighter!
So I considered a repeated build of a P-47D/Supermarine Attacker kitbash, just in American colors. But with the F9F relationship, I planned the integration of Panther parts, so that the new creation would look different from the Gu-1, but also show some (more) similarity to the Panther.
The plan appeared feasible. Again, the aircraft's core is an Academy P-47D, with its outer wings cut off. Cockpit and landing gear were retained. However, instead of Supermarine Attacker wings from a Novo kit, I attached F9F-2 wings from a Hasegawa kit. Shape-wise this worked fine, but the Panther wings are much thinner than the Thunderbolt’s, so that I had to integrate spacers inside of the intersections which deepen the Hasegawa parts. Not perfect, but since the type would feature folding wings, the difference and improvisation is not too obvious.
On the fuselage, the Thunderbolt’s air outlets on its flanks were faired over and most of the tail section cut away. In the lower part of the tail, a jet pipe (from a Heller F-84G) was added and blended with PSR into the Thunderbolt fuselage, similar to the Gu-1. A completely new fin was scratched from an outer wing section from a Heinkel He 189, in an attempt to copy the G-79B's shape according to the drawing I used as benchmark for the build. I also used the F9F's stabilizers. With clipped tips they match well in size and shape, and add to the intended Grumman family look. The original tail wheel well was retained, but the tail wheel was placed as far back as possible and replaced by the twin wheel from a Hasegawa F5U. The Panther’s OOB tail hook was integrated under the jet pipe, too.
The front section is completely different and new, and my choice fell on the turboprop-powered G-79B because I did not want to copy the Gu-1 with its radial engine. However, the new turboprop nose was not less complicated to build. Its basis is a 1:100 engine and contraprop from a VEB Plasticart Tu-20/95 bomber, a frequent ingredient in my builds because it works so well in 1:72 scale. This slender core was attached to the Thunderbolt's fuselage, and around this basis a new cowling was built up with 2C putty, once more in an attempt to mimic the original G-79B design as good as possible.
In order to blend the new engine with the fuselage and come close to the G-79B’s vaguely triangular fuselage diameter, the P-47's deep belly was cut away, faired over with styrene sheet, and everything blended into each other with more PSR work. As a final step, two exhaust pipes were mounted to the lower fuselage in front of the wings’ leading edge.
The air intakes for the jet booster are actually segments from a Sopwith Triplane fuselage (Revell) – an unlikely source, but the shape of the parts was just perfect. More PSR was necessary to blend them into the aircraft’s flanks, though.
Painting and markings:
As per usual, I'd rather go with conservative markings on a fictional aircraft. Matching the Korean War era, the aircraft became all-over FS 35042 (Modelmaster). A black ink wash emphasized the partly re-engraved panel lines, and some post shading highlighted panels.
The wings’ leading edges and the turboprop’s intake were painted with aluminum, similar edges on fin and stabilizers were created with silver decal material. The interior of cockpit and landing gear was painted with green chromate primer.
The markings were puzzled together. “Stars and Bars” and VF-53 markings were taken from a Hobby Boss F4U-4 kit. The blue fin tip is the marking for the 3rd squadron, so that the “307” tactical code is plausible, too (the latter comes from a Hobby Boss F9F-2). In order to keep things subtle and more business-like (after all, the aircraft is supposed to be operated during the ongoing Korean War), I did not carry the bright squadron color to any other position like the spinner or the wing tips.
After some final detail work and gun and exhaust soot stains, the kit was sealed with semi-gloss acrylic varnish (Italeri). Matt acrylic varnish was used for weathering effects, so that the aircraft would not look too clean and shiny.
While it is not a prefect recreation of the Grumman G-79B, I am quite happy with the result. The differences between the model and the original design sketch can be explained through serial production adaptations, and overall the whole thing looks pretty conclusive. In fact, the model appears from certain angles like a naval P-51 on steroids, even though the G-79B was a much bigger aircraft than the Mustang.
I kitbashed the Power Girl figure using the Jiaou doll instead of using the Tbleague body since the Jiaou seems much more curvey than the Tbleague bodies , especially the lower half of the bodies and she filled her suit a whole lot better .

Some background:
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 and dedicated attack aircraft threatened the ground troops from above, the need for more mobile and better-armed self-propelled anti-aircraft guns increased. As a stopgap solution the Wehrmacht initially adapted a variety of wheeled, half-track and tracked vehicles to serve as mobile forward air defense positions. Their tasks were to protect armor and infantry units in the field, as well as to protect temporary forward area positions such as mobile headquarters and logistic points.
These vehicles were only lightly armored, if at all, and rather mobilized the anti-aircraft weapons. As Allied fighter bombers and other ground attack aircraft moved from machine gun armament and bombing to air-to-ground rockets and large-caliber cannons, 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. Furthermore, the vehicle would have the same mobility as the battle tanks it protected.
Initial German AA-tank designs were the ‘Möbelwagen’ and the ‘Wirbelwind’, both conversions of refurbished Panzer IV combat tank chassis with open platforms or turrets with four 20mm cannon. Alternatively, a single 37mm AA gun was mounted, too – but all these vehicles were just a compromise and suffered from light armor, a high silhouette and lack of crew protection.
Further developments of more sophisticated anti-aircraft tank designs started in late 1943 and led into different directions. One development line was the ‘Kugelblitz’, another Panzer IV variant, but this time the ball-shaped turret, armed with very effective 30 mm MK 103 cannon, was fully integrated into the hull, resulting in a low silhouette and a protected crew. However, the ‘Kugelblitz’ only featured two of these guns and the tilting turret was very cramped and complicated. Venting and ammunition feed problems led to serious delays and a prolonged development stage.
The ‘Coelian’ family of bigger turrets with various weapon options for the Panzer V (the ‘Panther’) was another direction, especially as a response against the armored Il-2 attack aircraft at the Eastern front and against flying targets at medium altitude. Targets at high altitude, esp. Allied bombers, were to be countered with the very effective 8.8 cm Flak, and there were also several attempts to mount this weapon onto a fully armored hull.
The primary weapon for a new low/medium altitude anti-aircraft tank was to become the heavy automatic 55 mm MK 214. Like the 30 mm MK 103 it was a former aircraft weapon, belt-fed and adapted to continuous ground use. However, in early 1944, teething troubles with the ‘Kugelblitz’ suggested that a completely enclosed turret with one or (even better) two of these new weapons, mounted on a ‘Panther’ or the new E-50/75 tank chassis, would need considerable development time. Operational vehicles were not expected to enter service before mid-1945. In order to fill this operational gap, a more effective solution than the Panzer IV AA conversions, with more range and firepower than anything else currently in service, was direly needed.
This situation led to yet another hasty stopgap solution, the so-called ‘Ostwind II’ weapon system, which consisted primarily of a new turret, mated with a standard medium battle tank chassis. It was developed in a hurry in the course of 1944 and already introduced towards the end of the same year. The ‘Ostwind II’ was a compromise in the worst sense: even though it used two 37 mm FlaK 43 guns in a new twin mount and offered better firepower than any former German AA tank, it also retained many weaknesses from its predecessors: an open turret with only light armor and a high silhouette. But due to the lack of time and resources, the ‘Ostwind II’ was the best thing that could be realized on short notice, and with the perspective of more effective solutions within one year’s time it was rushed into production.
The ‘Ostwind II’ system was an open, roughly diamond-shaped, octagonal turret, very similar in design to the Panzer IV-based ‘Wirbelwind’ and ‘Ostwind’ (which was re-designated ‘Ostwind I’). As a novelty, in order to relieve the crew from work overload, traverse and elevation of the turret was hydraulic, allowing a full elevation (-4° to +90° was possible) in just over four seconds and a full 360° traverse in 15 seconds. This had become necessary because the new turret was bigger and heaver, both the weapons and their crews required more space, so that the Ostwind II complex could not be mounted onto the Panzer IV chassis anymore and movement by hand was just a fallback option.
In order to provide the ‘Ostwind II’ with a sufficiently large chassis, it was based on the SdKfz. 171 Panzer V medium battle tank, the ‘Panther’, exploiting its bigger turret ring, armor level and performance. The Panther chassis had, by late 1944, become available for conversions in considerable numbers through damaged and/or recovered combat tanks, and updated details like new turrets or simplified road wheels were gradually introduced into production and during refurbishments. Mounting the ‘Ostwind II’ turret on the Panzer VI (Tiger) battle tank chassis had been theoretically possible, too, but it never happened, because the Tiger lacked agility and its protection level and fuel consumption were considered impractical for an SPAAG that would typically protect battle tank groups.
The ‘Ostwind II’ turret was built around a motorized mount for the automatic 3.7 cm FlaK 43 twin guns. These proven weapons were very effective against aircraft flying at altitudes up to 4,200 m, but they also had devastating effect against ground targets. The FlaK 43’s armor penetration was considerable when using dedicated ammunition: at 100 m distance it could penetrate 36 mm of a 60°-sloped armor, and at 800 m distance correspondingly 24 mm. The FlaK 43’s theoretical maximum rate of fire was 250 shots/minute, but it was practically kept at ~120 rpm in order to save ammunition and prevent wear of the barrels. The resulting weight of fire was 76.8 kg (169 lb) per minute, but this was only theoretical, too, because the FlaK 43 could only be fed manually by 6-round clips – effectively, only single shots or short bursts could be fired, but a trained crew could maintain fire through using alternating gun use. A more practical belt feed was at the time of the Ostwind II's creation not available yet, even though such a mechanism was already under development for the fully enclosed Coelian turret, which could also take the FlaK 43 twin guns, but the armament was separated from the turret crew.
The new vehicle received the official designation ‘Sd.Kfz. 171/2 Flakpanzer V’, even though ‘Ostwind II’ was more common. When production actually began and how many were built is unclear. The conversion of Panther hulls could have started in late-1944 or early-1945, with sources disagreeing. The exact number of produced vehicles is difficult to determine, either. Beside the prototype, the number of produced vehicles goes from as little as 6 to over 40. The first completed Ostwind II SPAAGs were exclusively delivered to Eastern front units and reached them in spring 1945, where they were immediately thrown into action.
All Flakpanzer vehicles at that time were allocated to special anti-aircraft tank platoons (so-called Panzer Flak Züge). These were used primarily to equip Panzer Divisions, and in some cases given to special units. By the end of March 1945, there were plans to create mixed platoons equipped with the Ostwinds and other Flakpanzers. Depending on the source, they were either to be used in combination with six Kugelblitz, six Ostwinds and four Wirbelwinds or with eight Ostwinds and three Sd.Kfz. 7/1 half-tracks. Due to the war late stage and the low number of anti-aircraft tanks of all types built, this reorganization was never truly implemented, so that most vehicles were simply directly attached to combat units, primarily to the commanding staff.
The Ostwind II armament proved to be very effective, but the open turret (nicknamed ‘Keksdose’ = cookie tin) left the crews vulnerable. The crew conditions esp. during wintertime were abominable, and since aiming had to rely on vision the system's efficacy was limited, esp. against low-flying targets. The situation was slightly improved when the new mobile ‘Medusa’ and ‘Basilisk’ surveillance and target acquisition systems were introduced. These combined radar and powerful visual systems and guided the FlaK crews towards incoming potential targets, what markedly improved the FlaKs' first shot hit probability. However, the radar systems rarely functioned properly, the coordination of multiple SPAAGs in the heat of a low-level air attack was a challenging task, and - to make matters worse - the new mobile radar systems were even more rare than the new SPAAGs themselves.
All Ostwind II tanks were built from recovered ‘Panther’ battle tanks of various versions. The new Panther-based SPAAGs gradually replaced most of the outdated Panzer IV AA variants as well as the Ostwind I. Their production immediately stopped in the course of 1945 when the more sophisticated 'Coelian' family of anti-aircraft tanks with fully enclosed turrets became available. This system was based on Panzer V hulls, too, and it was soon followed by the first E-50 SPAAGs with the new, powerful twin-55 mm gun.

The kit and its assembly:
This was a spontaneous build, more or less the recycling of leftover parts from a 1:72 Revell Ostwind tank on a Panzer III chassis that I had actually bought primarily for the chassis (it became a fictional Aufklärungspanzer III). When I looked at the leftover turret, I wondered about a beefed-up/bigger version with two 37 mm guns. Such an 'Ostwind II' was actually on the German drawing boards, but never realized - but what-if modelling can certainly change that. However, such a heavy weapon would have to be mounted on a bigger/heavier chassis, so the natural choice became the Panzer V, the Panther medium battle tank. This way, my ‘Ostwind II’ interpretation was born.
The hull for this fictional AA tank is a Hasegawa ‘Panther Ausf. G’ kit, which stems from 1973 and clearly shows its age, at least from today’s point of view. While everything fits well, the details are rather simple, if not crude (e. g. the gratings on the engine deck or the cupola on the turret). However, only the lower hull and the original wheels were used since I wanted to portray a revamped former standard battle tank.
The turret was a more complicated affair. It had to be completely re-constructed, to accept the enlarged twin gun and to fit onto the Panther hull. The first step was the assembly of the twin gun mount, using parts from the original Ostwind kit and additional parts from a second one. In order to save space and not to make thing uber-complicated I added the second weapon to the right side of the original gun and changed some accessories.
This, together with the distance between the barrels, gave the benchmark for the turret's reconstruction. Since the weapon had not become longer, I decided to keep things as simple as possible and just widen the open turret - I simply took the OOB Ostwind hexagonal turret (which consists of an upper and lower half), cut it up vertically and glued them onto the Panther turret's OOB base, shifting the sides just as far to the outside that the twin gun barrels would fit between them - a distance of ~0.4 inch (1 cm). At the rear the gap was simply closed with styrene sheet, while the front used shield parts from the Revell Ostwind kit that come from a ground mount for the FlaK 43. Two parts from this shield were glued together and inserted into the front gap. While this is certainly not as elegant as e. g. the Wirbelwind turret, I think that this solution was easier to integrate.
Massive PSR was necessary to blend the turret walls with the Panther turret base, and as a late modification the opening for the sight had to be moved, too. To the left of the weapons, I also added a raised protective shield for the commander.
Inside of the turret, details from the Ostwind kit(s), e. g. crew seats and ammunition clips, were recycled, too.
Painting and markings:
Since the Ostwind II would be based on a repaired/modified former Panzer V medium battle tank, I settled upon a relatively simple livery. The kit received a uniform finish in Dunkelgelb (RAL 7028), with a network of greenish-grey thin stripes added on top, to break up the tank's outlines and reminiscent of the British ‘Malta’ scheme, but less elaborate. The model and its parts were initially primed with matt sand brown from the rattle can (more reddish than RAL 7028) and then received an overall treatment with thinned RAL 7028 from Modelmaster, for an uneven, dirty and worn look. The stripes were created with thinned Tamiya XF-65 (Field Grey).
Once dry, the whole surface received 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, grey, iron 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.
A bit of recycling and less exotic than one would expect, but it’s still a whiffy tank model that fits well into the historic gap between the realized Panzer IV AA tanks and the unrealized E-50/75 projects. Quite subtle! Creating the enlarged turret was the biggest challenge, even, even more so because it was/is an open structure and the interior can be readily seen. But the new/bigger gun fits well into it, and it even remained movable!

Some background:
The mighty Suchoj SuCh-1 started its life in early March 1943, when the Sukhoi OKB finished work on the design of a high-speed fighter with a unique powerplant arrangement. The aircraft was an all-metal low-wing monoplane with conventional tail surfaces. The three-section wings had constant dihedral and basically trapezoidal planform; the stabilizers had zero dihedral.
Two Klimov M-107 water-cooled Vee-12 engines, each with a. take-off power of 1 ,600 hp (1,193 kW) and a maximum design power of 1,500 hp (1,119 kW) at 5,500 m (18,045 ft), were mounted in the center fuselage in a staggered-tandem arrangement: the front engine was offset to starboard and of the rear one to port. Thus, the total power was increased but the drag was the same as for a single-engined aircraft, which was expected to increase fight speed considerably. Consequently, the project was internally designated 'I-2M107', literally "Article powered by two M107 engines".
Furthermore, the left cylinder bank of the front engine and the right cylinder bank of the rear engine were disposed vertically, so that each engine had one set of exhaust stubs on top of the fuselage and one on the fuselage side. Both engines drove a single three blade tractor propeller of 4.0 m (13 tt 2 in) diameter via parallel extension shafts and a common reduction gearbox. Both water radiators were located side by side in a chin housing, while the oil coolers were buried in the wings. The total fuel capacity of the four tanks arranged in the center fuselage was 1,113 litres (244.86 Imp. gal).
Because of the power plant arrangement and the large ground angle (necessary to give adequate ground clearance for the large propeller) the cockpit was offset to port and placed ahead of the wing leading edge to provide better forward visibility on take-off and landing. The cockpit was protected by a bulletproof windscreen, a front armor plate and an armored backrest; the armor weight totaled 70kg (154Ib).
The main landing gear units with 800 x 280 mm (31.5x11 in) wheels retracted inwards into the wing roots and the 400 x 150 mm (15.7 x 5.9 in) tail wheel retracted aft. The fighter's armament consisted of two wing-mounted 12.7-mm Berezin UBS machine-guns firing outside the propeller disc and a single 20-mm ShVAK cannon firing through the propeller hub*.
A full-scale mock-up was inspected in December 1943, and with German long range bombers threatening the Western front line as well as the lack of a fast and powerful fighters to intercept them (the earlier MiG-5 had turned out to be a disappointment, and Mikoyan's I-211/221 family if high altitude fighters also suffered from serious technical problems at that time), OKB Suchoj received an immediate go-ahead for further development of the SuCh-1, how the I-2M107 was now officially called, since Vladimir A. Chizhevskiy took lead of the project.
In the course of 1944 three prototypes went through a fast development program. While the aircraft itself was easy to handle, overheating problems and trouble with the gearbox for the two engines could only partly be rectified - esp. the power transmission should remain the SuCh-1s Achilles Heel.
Anyway, the Su-5 was ready for service introduction towards late 1944, and the powerful type was exclusively to be used as an interceptor. Several improvements had been made, compared to the prototypes: now two slightly more powerful Klimov VK-107A engines were used, which were better suited for high altitude operations, and the chin-mounted water cooler was considerably enlarged. The oil coolers had been re-designed and they were now placed under the wing roots.
The wing span had been extended by 6' and a bigger (now 4.3m diameter!), four-bladed propeller was added in order to improve performance at high altitude. No pressurized cabin was installed, but the cockpit received an extended glazing for better all-round field of vision.
Armament had also been augmented: now a Nudelman N-23 23mm cannon was firing through the propeller hub, and the number of UBS machine-guns in the wings was increased to four.
As initial duty experience was gathered, it became quickly clear that the firepower had to be augmented, so that the propeller-hub-mounted 23mm cannon was quickly replaced by a Nudelman-Richter NR-37 37mm cannon, and the four wing-mounted UBS machine guns were replaced by two 20-mm ShVAK cannons or even two Nudelman N-23 23mm cannons - the latter became the production standard from March 1945 on, even though the type's designation did not change.
Experience also showed that the overheating problem had been cured, but the complicated gear box tended to malfunction, esp. when full power was called for in aerial combat: high G forces took their toll and damaged the bearings, even warping the extension shafts and structural parts, so that some SuCh-1 were literally torn apart in mid-air.
The high torque powers of the large propeller also took their toll on handling: starting and landing was described as "hazardous", esp. when the fuel tanks were empty or in cross winds.
Consequently, SuCh-1 pilots were warned to engage into any dogfight or enter close combat with single-engined enemy fighters, and just focus on large enemy aircraft.
On the other side, the SuCh-1's powerful cannon armament made it a deadly foe: a single hit with the NR-37 cannon could down an aircraft, and its top speed of roundabout 700 km/h (435 mph) was more than enough for the Luftwaffe's heavy bomber types like the He 177.
Several engine and armament experiments were undertaken. For instance, at least one SuCh-1 was outfitted with a Nudelman-Sooranov NS-45 45mm cannon firing through the propeller hub, even a 57mm cannon was envisaged. Furthermore, one airframe was prepared to carry two Charomskiy M-30V 12 cylinder diesel engines, in order to produce a heavy long-range escort fighter (internally called I-2M30V).
In order to minimize the torque problems a contraprop arrangement with two three-bladed propellers and a diameter of only 3.6m was under development.
All in all only 120 of these powerful machines were built until the end of hostilities, as the feared mass attacks of German long range bombers did not materialize. as the Su-7 was complicated to operate and jet engines promised a far more efficient way of propulsion for high speeds, the type was already retired in 1947 and replaced by 1st generation jet fighters like the Yak-15 and MiG-9, which carried a similar armament, attained a better performance (except for the range) but weighed only half of the large and heavy SuCh-1.

The kit and its assembly (a long story!):
This abomination of an aircraft is/was real, even though the I-2M107 was never built – the fictional name Suchoj-Chizhevskiy SuCh-1 was actually chosen because I could not find any plausible Su-X code for a WWII fighter. Vladimir A. Chizhevskiy actually joined the Suchoj OKB in mid WWII, so I deemed this alternative to be plausible.
I had this on the agenda for a long time, but the horrors of kitbashing kept me from building it - until now. The current Anthony P memorial Group Build (for the deceased fellow member at whatifmodelers.com, RIP) was a good motivation to tackle this brute thing. Fortunately, I already had some major ingredients in store, so work could start asap.
From that, anything else was improvised from the scrap box, and with only a three side view of the I-2M107 as guidance. It became a true Frankenstein creation with...
● Fuselage and inner wings from the (horrible) NOVO Attacker
● Wings from an Italeri Fw 190 D-9 attached to them
● Nose is a resin Griffon from an Avro Lincoln conversion set from OzMods
● Tail cone is a radar nose from an F-4J Phantom II
● Tail fin is a horizontal stabilizer from a Matchbox SB2C Helldiver
● Vertical stabilizers come from a Matchbox Me 410
● Oil coolers are modified front landing gear wells from two Revell G.91 kits
● Cockpit hood comes from a Revell P-39 Airacobra
● Landing gear comes from an Italeri Fw 190 D-9, covers were modified/improvised
● Main wheels belong to a MPM Ryan Dark Shark
● Tail wheel belongs to a Matchbox Harrier
● The propeller was scratched, IIRC from a Grumman Hellcat drop tank front and blades from an Airfix A-1 Skyraider. Inside, a metal axis was mounted.
.
Work started with the fuselage and the wings as separate segments.
The Attacker fuselage lost its fin and the cockpit and air intakes were simply cut away, just as the tail pipe. The resin Griffon was slightly shortened at the front, but more or less directly attached to the fuselage, after I had cut out openings for the four rows of exhaust nozzles.
Then, the new tail cone was glued onto the end and the original fairings for the Attacker's stabilizer cut away and sanded even - anything had to be made new.
The wings were a bit tricky. I had hoped to use the Attacker's OOB wings, but these were not only much too small and did not have the proper shape, they also lacked landing gear wells!
Finding a solution was not easy, and I had to improvise. After some trials I decided to cut the Attacker wing span at about the width where the guns are located, and then add Fw 190 wings.
The depth would be fine, even though the Fw 190 wings were a bit thicker, and they offered a leading edge kink which was good for the original and characteristic I-2M107's wing root extensions. The latter were sculpted from a 6mm thick core or styrene sheet, added to the Attacker parts' leading edge, and the rest, as well as the lacking Attacker wing's thickness, sculpted with 2C and later NC putty.
Furthermore I cut out and sculpted landing gear wells, another challenging, since these had to cover the Attacker/Fw 190 parts' intersection! LOTS of putty work, sanding and shaving, but as a benefit I was able to use the Attacker kit's original wing/fuselage joints. Effectively, my placement turned out to be a bit far outside, so the track appears too wide - the price to pay when you work on single parts. Anyway, I left it was it turned out, as a major correction at a late working stage would mean to tear anything apart again...
Back to the nose: adding the propeller and the cockpit into the massive nose was the next working station. The propeller had to be huge, and also needed a rather big spinner. A contraprop was ruled out, even though it would have looked great here. But eventually I settled for a scratch-built thing, made from a teardrop-shaped drop tank front onto which the four blades from a A-1 Skyraider were glued. Probably the biggest prop I have ever put onto a 1:72 scale model! Since the resin nose was massive, drilling a hole and adding a metal axis to the propeller was enough.
With that in place I started carving out a cockpit opening - it worked better and easier than expected with a mini drill and a coarse shaving head! The opening is still rather small, a seat and a pilot hardly fit, but it works - I found a rather smallish pilot figure, and added a seat and some other small details from the scrap box, just to have something inside.
For a canopy I found a very old (30 years, I guess...) clear part from a Revell P-39 Airacobra in the scrap box, which was almost perfect in shape and width. It was a bit blind and stained with ancient enamel paint, but some wet sanding and serious polishing almost got it back to translucent status. Since I would not open the cockpit, this was a sufficient solution.
The asymmetrical cockpit opening was, in an initial step, faired with styrene strips, for a rough outline, and then sculpted with 2C and later NC putty, blending it into the rest of the fuselage.
For the tail surfaces, the SB2C stabilizer was cut away at its base - it is not a bad donation piece, its shape and rudder come pretty close to the I-2M107's original design!
The stabilizers I used on my kitbash come from a Me 410, and their leading edge was a cut away so that the sweep angle would be a bit larger. They lack depth, compared to the I-2M107's original design, but since the wings have become more slender, too, I think it's a good compromise, and the best what I had at hand in the spares stash.
Finally, and before detail work could start, the wings were attached to the fuselage. I eventually set them back by ~6mm, so that the new, extended leading edge would match the respective fairing on the fuselage. The resulting gap at the trailing edge was, again, filled with 2C and NC putty.
A personal change was a different oil cooler arrangement. The original location was to be in the wings' leading edge, just in front of the landing gear wells - but that appeared a bit doubtful, as I could not find a plausible solution where the exit for the air would be? Consequently, and in order to avoid even more messy putty sculpting on the wings, I decided to re-locate the oil coolers completely, into shallow, tunnel-like fairings under the wing roots, not unlike the radiator arrangement on a Spitfire or Bf 109.
In order to check the surface quality I decided to add a coat of grey primer, once the fuselage/wing segments had been connected. This showed only minor flaws, but made another turn with NC putty and wet sanding necessary.
Now it was time for finishing touches, e .g. mounting the landing gear, completing the cockpit and adding exhaust stubs - cut individually from HO scale model railroad roof tiles and inserted into the four fuselage fairings.
The canopy was fixed into place with white glue, which also helped closing some small gaps.

Painting and markings:
While the I-2M107 looks odd, to say the least, I wanted to keep the paint scheme rather simple and quasi-authentic. I went for a pale grey/green camouflage, used e. g. on late war Yakovlev Yak-3 fighters.
Basic colors are Humbrol 31 (Slate Grey, it has a very greenish, even teal, hue), ModelMaster 1740 (Dark Gull Grey, FS 36231) and Humbrol 167 (Barley Grey) for the lower sides with a wavy waterline. Since only marginal surface details were left over, I decided to fake panels and panel lines with paint.
Panels were simulated with lighter shades of the basic tones (RLM 62 from ModelMaster, Humbrol 140 and 127 below), panel lines were painted with highly thinned grey acrylic paint and a special brush - in German it's called a 'Schlepppinsel', it's got very long hairs and is also used to paint scallops on car models, and similar things are used for real car tuning/custom paintwork, too.
Sure, the painted panel lines are a bit rough, but I did not want to risk any damage through manual engraving on the rather delicate mixed-media surface of the kitbashed model. For an overall look or first impression it's very good, though.
As 'highlights' I added a white spinner and half of the fin was painted white, too.
The decals were puzzled together. The flashes and the tactical code number come from a Hobby Boss La-7, the Red Stars, IIRC, belong to a vintage MiG-21F from Hasegawa. The "Rodinu" slogan actually belongs to a 1:35 Soviet Tank decals set.
Finally, after some additional dry painting with light grey, some oil stains around the engines and coolers and soot stains at the exhaust stubs and guns (painted, plus some grinded graphite, as it yields a nice, metallic shimmer that looks like oil or burnt metal), everything was sealed under a coat of matt acrylic varnish.
If it had been built, the Suchoj I-2M107 must have been an impressive aircraft - it was bigger than a P-47 Thunderbolt or an A-1 Skyraider, and one can only wonder how its field performance would have been?
Similar concepts had been underway in UK, too, e. g. for a heavy naval attack aircraft, but the I-2M107 with its asymmetrical cockpit and engine arrangement were unique. A worthy whif, even if some details like the landing gear or the borrowed nose section are not 100% 'correct'.
