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'.

In the period immediately after the Second World War the world found itself with hundreds of thousands of surplus aircraft and just as many surplus aviators. Most aircraft would meet the salvage blade and the smelter’s fiery furnace. Most pilots would return to civilian life, the bulk of them never to fly again.

 

With the plethora of military aircraft languishing in desert lots awaiting a certain fate, some of those disenfranchised aviators and aircraft designers would look to new growing markets for salvation. One of these emerging markets was the new-found requirement for fast and capable business transport aircraft for executives looking to link business interests across the vast distances of the nation. With few purpose-built business aircraft available for executives, medium bombers became the drug of choice for high flying big shots—fast, powerful and, with the right interior appointments, a visual statement of their success and power.

 

In early variants like the Executive, On Mark simply removed military equipment and replaced them with fairings and civil avionics, sealed the bomb bay doors, soundproofed the cabin, and added additional cabin windows. Later models had special wing spars designed to give more interior room, pressurization and equipment from bigger surplus aircraft such as DC-6 brakes and flat glass cockpit windows. It was an elegant mashing together of equipment, but it was not a true business aircraft.

 

In the Sixties, Jet Craft Ltd. of Las Vegas, Nevada, went for a different interpretation of the same topic: The company had purchased a number of former Royal Australian Air Force Vampire trainers and RCAF single-seaters, which were to be converted to a new design for a business aircraft called 'Mystery Jet', offering 4-8-seats.

 

Jet Craft worked with stellar British conversion experts Aviation Traders to do the structural design work. Aviation Traders Limited (ATL) was a war-surplus aircraft and spares trader formed in 1947. In 1949, it began maintaining aircraft used by some of Britain’s contemporary independent airlines on the Berlin Airlift. In the early 1950s, it branched out into aircraft conversions and manufacturing.

 

Aviation Traders worked on the drawings and the structural mock-ups. A full-scale mock-up of the Mystery Jet languished at Southend airport for a decade, trying to lure owners and operators into buying it. And this actually happened: about twenty former Vampire airframes were converted into Mystery Jet business aircraft, tailored to the customers' needs and desires.

 

The Mystery Jet was just what it looked like: a former De Havilland Vampire with a new, roomy nose section grafted onto it. The cabin was pressurized, and was available in two different lengths (130 and 160 inches long, with two or three rows of seats and reflected in the aircraft's title) and several window and door options - the most exotic option being the "Landaulet" cabin which featured a panoramic roof/window installation over the rear pair of seats (or, alternatively, a two-seat bench).

 

The original Goblin engine was retained, CG was retained due to the fact that the new cabin was, despite being considerably longer than the Vampire's nose, the biggest version being more than 8 feet longer. The new front section was much lighter, though, e. g. through the loss of the heavy cannons and their armament, as well as some more military avionics. The loss of fuel capacity through the enlarged cabin was compensated through fixed wing tip tanks, so that range was on par with the former military jet, just top speed and ceiling were slightly inferior.

 

Anyway, prices were steep and from the United States more modern and economical offerings ruled the market. Maintaining a former military jet was also a costly business, so, consequently, after a slight buzz (more of a hum, actually) in the early Seventies, the Mystery Jet and Jet Craft of Las Vegas, also fuelled by some dubious business practices by the company's owner, disappeared. Even further developments of the original concept, e .g. with a wide body for up to 14 passengers and two engines, would not save the Mystery Jet from failure.

The kit and its assembly:

The first finished work in 2017 is a different kind of whif, one of the few civilian models in my collection. This conversion looks sick, but ,as weird as it may seem, the Business-Jet-From-Vintage-Vampires idea was real. For more information, and the source from where some of the backgound story was gathered, please check:

Anyway, my build is just a personal interpretation of the original concept, not a true model of the Mystery Jet. In fact, this was limited through the donor parts for this kitbash.

 

The rear end was the smaller problem: Airfix offers a very good Vampire T.11 trainer with excellent detail and fit - the passenger cabin was the bigger challenge. Finding "something" that would fit in shape and especialsl size was not easy - my first choice was a nose section from a vintage 1:100 Antonow An-24 from VEB Plasticart (still much too wide, though), and the best solution came as an accidental find in a local model kit shop where I found a heavily discounted MPM Focke Wulf Fw 189 B-0 trainer.

 

The reason: the kit was complete, but the bag holding the sprues must have been heated immensely during the packaging process: the main sprues were horrible warped - except for some single parts including the canopies and the sprue with the cabin! Height wind width were perfect, only the boxy shape caused some headaches. But I guess I would not find anything better...

 

That said, the transplantation mess started. I never built any of the two donor kits before, so I carefully tried to find the best place where to cut the Vampire's nose - I ended up with a staggered solution right in front of the wing root air intakes.

The Fw 189's cabin was bit more tricky, because I had to get rid of the original wing roots and wanted to use as much space as possible, up to the rear bulkhead and together with the rear cabin window. The idea was to blend the Fw 189's roof line into the Vampire's engine section, while keeping the original air intake ducts, so that the overall arrangement would look plausible.

 

The result became a pretty long nose section - and at that time the tail booms were not fited yet, so I was not certain concerning overall proportions. The cabin's underside had to be improvised, and blending the boxy front end with a flat underside into the tubby, round Vampire fuselage caused some headaches. I also had to re-create the lower flank section with styrene sheet, because I had originally hoped that I could "push" the new cabin between the wing roots - but that space was occupied by the Goblin's inlet ducts.

 

Inside of the cabin, the original floor, bulkheads and dashboard were used, plus five bucket seats that come with the MPM kit. In order to hide the body work from the inside, side panels from 0.5mm styrene sheet were added in the cabin - with the benefit of additional stability, but also costing some space... Since the machine was built with closed cabin, a pilot was added - actually a bash of a WWII Matchbox pilot and a German officer from an ESCI tank kit. Looks pretty good and "professional". ;-)

 

Once the cabin was in place, lots of PSR followed and the tail booms could be fitted. To my relief, the longer nose did not look too unbalanced (and actually, design sketches for the original Mystery Jet suggest just this layout!) - but I decided to add wing tip tanks which would beef up wingspan and shift the visual mass slightly forward. They come from an 1:100 Tamiya Il-28, or better the "R" recce variant.

 

The only other big change concerned the nose wheel. While the OOB wheel and strut were used, the well is now located in front of the wheel and it would retract forwards, giving the nose a more balanced look - and the cabin arrangement made this change more plausible, too.

 

Another addition were three small porthole windows in the solid parts of the cabin flanks - one of them ending up in the middle of the cabin door on starboard, where a solid part of the canopy roof lent itself for a good place just behind the pilots' seats.

  

Painting and markings:

I cannot help it, but the thing looks like a design from a vintage Tintin or Yoko Tsuno comic! This was not planned or expected - and actually the paint scheme evolved step by step. I had no plan or clue what to apply - the real Mystery Jet mock-up in silver with blue trim looked sharp, but somehow I did not want blue. So I started with the interior (out of a necessity, as the fuselage had to be closed before any further work progress at some point) and settled for plushy, British colors: Cream (walls and roof) and Claret-Red (carpet and seats).

 

I tried to find something for the outside that would complement this choice of colors, and eventually settled on Ivory and White (upper and lower fuselage halves, respectively) with some deep red trim, plus pale grey wing surfaces. I even considered some thin golden trim lines, but I think this would have been too much?

 

The trim was created with decals tripes from generic sheet material, the black anti-glare panel was painted, though. As a color contrast I painted some of the upper canopy panels in translucent, light blue, and this looks very good.

 

The wings received a lightb treatment with thinned black ink, in order to emphasize the engravings. No post-shading was done, though, for a rather clean look.

 

Most markings were puzzled together; the registration G-AZRE actually belonged to a Vickers Vanguard (from the 1:144 Airfix kit), the large letters above and under the wings were created with single 45° letters (USAF style). Most stencils come from a Vampire trainer aftermarket sheet from Xtradecal, from the OOB sheet only the "No step" warnings on the wings were used.

 

Finally, the kit was sealed with a semi-matt coat of varnish, except for the anti-glare panel, which recived a matt coat. The three small windows received artificial panes made from Clearfix, after their rims had been painted black.

  

A messy project, and you better do not take a close look. But the overall elegance of this creation surprises me - the real Mystery Jet already looked sleek, and this model, despite a more blunt nose, confirms this impression. The colors work together well, too - and the thing has a dedicated retro feel about it. Tintin might be on board, as well as Elton John, both sharing a cigar on the rear seats... ;)

Some background:

The Fouga CM.170 Magister was a 1950s French two-seat jet trainer aircraft, developed and manufactured by aircraft company Fouga. Due to industrial mergers, the aircraft has been variously known as the Fouga CM.170 Magister, Potez (Fouga) CM.170 Magister, Sud Aviation (Fouga) CM.170 Magister and Aérospatiale (Fouga) CM.170 Magister, depending on where and when they were built.

 

In 1948, development commenced at Fouga on a new primary trainer aircraft design that harnessed newly developed jet propulsion technology. The initial design was evaluated by the French Air Force and, in response to its determination that the aircraft lacked sufficient power for its requirements, was enlarged and adopted a pair of Turbomeca Marboré turbojet engines. First flying on 23 July 1952, the first production order for the type was received on 13 January 1954. Export orders for the Magister were received, which included arrangements to produce the type under license in Germany, Finland, and Israel. In addition, the related CM.175 Zéphyr was a carrier-capable version developed and produced for the French Navy.

 

While primarily operated as a trainer aircraft, the Magister was also frequently used in combat as a close air support platform by various operators. In the latter capacity, it saw action during the Six-Day War, the Salvadoran Civil War, the Western Sahara War, and the Congo Crisis. In French service, the Magister was eventually replaced by the Dassault/Dornier Alpha Jet, and a navalized variant (the CM.175 “Zéphyr”) was procured and operated from 1959 onwards by the Aéronavale.

 

Beyond that, the basic 1950 design was considered for several upgrades or specialized variants – including a high altitude trainer or a dedicated single-seat attack aircraft. In 1957 even a supersonic variant was proposed: the CM.174, which featured swept wings and tail surfaces. However, this initial aircraft never made it to the hardware stage because wind tunnel tests revealed serious compressibility issues at speeds beyond Mach 0.65, and that the potential gain in performance through the new wings could not be tapped.

 

However, this was not the end of the Magister’s potential; in 1957 Fouga presented a model of the CM 194 at the Paris Air Show – a much updated aircraft, powered by a pair of stronger Gabizo engines and capable of supersonic speed, even though only in a dive. French officials and some potential foreign customers (e.g. Israel) were interested enough to convince Fouga to build a demonstrator, even though as a private venture. The first prototype left the Toulouse factory in May 1958, the first type to bear the Potez designation after Fouga had just been purchased by the firm.

 

The CM.194 differed in some details from the model that had been presented – primarily in order to save development time and costs. The basic fuselage structure from the original CM.170 was retained, but the CM.194 introduced completely new wings and tail surfaces, a modified landing gear, a pointed nose and an elongated spine fairing that helped improve the aircraft’s aerodynamics for the flight in the Mach 1 region. Power came from a pair of Turbomeca Gabizo, but in order to improve the aircraft’s performance and make it suitable for the advanced jet fighter trainer role, the relatively small engines even received afterburners (an arrangement originally developed for the stillborn Breguet Br 1001 “Taon” tactical fighter). With this extra power, the CM.194 was now able to break the sound barrier in level flight and attain a top speed of Mach 1.18, and the type could carry a considerably higher payload than the original CM.170.

 

Flight tests started in late 1958 and revealed good handling characteristics, even though longitudinal stability near Mach 1 was considered as unsatisfactory, and the air intakes had to be modified because of airflow problems and engine surges at supersonic. It took until mid 1959 until an enlarged butterfly tail with crescent shape, together with an extended spine fairing, eventually solved the stability problem. The engine surge problem was solved through the introduction of movable shock cones in the air intakes, similar to the “souris” (mice) arrangement on Dassault’s Mirage III and IV.

Two more prototypes had been built at that time, being marketed as the “Magister Supersonique”, or “Magister SS” for short, and a demonstration tour around the globe in many countries of Magister operators was conducted from October 1959 until April 1960.

However, the CM.194 did not meet much interest. Even though many air forces, also smaller ones, were about to enter the supersonic age and were looking for advanced trainers, the market had been conquered by politically endorsed alternatives in the meantime, namely the Northrop T-38/F-5B and the MiG-21U, and these contenders were much more capable than the relatively light CM.194.

 

Nevertheless, the French air force procured 42 CM.194 trainers, the first operational aircraft being delivered in early 1963, and some other countries ordered the type, too, including Austria, Belgium, Lebanon and Morocco. Israel even secured license production rights of the aircraft as the IAI T-270 “Drowr” (Swallow). A total of 132 aircraft were built until 1974, and the last CM.194 was retired by El Salvador in 1995.

The kit and its assembly:

This little what-if model is actually based on a real world design – the potentially supersonic Fouga CM 194 was actually presented in model form in 1957, but it never made it to the hardware stage. I found this aircraft in a book about French aircraft projects and had this build on my long project list for a while. When a fellow modeler at whatifmodelers.com (Weaver) presented a very nice swept wing Magister (an Airfix CM 170 with G.91 wings and F-86 stabilizers), I took it as a motivation and prepared a build of my own.

 

My build differs from Weaver’s approach, though, even though the G.91 wings are a very natural option for the slender Magister. In my case, the fuselage was taken from a Heller CM 170, including the cockpit except for the bucket seats, which were replaced by more appropriate ejection seats. I also used G.91 wings for my build, but these came from the Revell kit. And even though I had a pair of F-86 stabilizers at hand (which are a very good addition to the G.91 wings), I did not use them because I found them to be too small for a butterfly tail on a Magister. After all, two aerodynamic surfaces have to do the job of three on a conservative tail, so that the sum of the surfaces’ areas have to be similar. The best alternative I could find in my donor bank was a pair of stabilizers from a Matchbox Harrier; while their shape looks a little odd, their sweep angle is fine and their size works well.

 

Beyond these obvious changes, some other modifications ensued. The nose tip was changed into a pointed shape, and the area behind the cockpit (the canopy is OOB, just cut into pieces for open display) was raised through the integration of a drop tank half and some serious PSR – inspired by the look of Fouga’s first attempt to make the Magister supersonic, the CM 174. Since the G.91 wings came with different landing gear wells, I decided to change the landing gear itself and use the G.91’s main struts and covers, while the Magister’s OOB main wheels were kept. The front leg was changed in so far that I attached it to the rear end of its well, and I used a slightly bigger wheel (IIRC from an 1:144 B-1B). All in all the aircraft’s stance was raised, it looks much more mature now. And in order to keep its lines clean I did not add any external weapons or even pylons. After all, it’s a flight trainer.

 

Another modification concerns the engines – for a supersonic aircraft I added small shock cones in the air intakes (scratched from styrene profile) and I changed the exhaust section, so that bigger/stronger engines would be plausible. I implanted a pair of modified lift engines from a Kangnam Yak-38 kit – I thought they’d be small enough, but on the compact Magister they still appear big! Luckily I found the Br 1001 “Taon” and its afterburner Gabizo engines in literature, so that the arrangement on the model can at least be explained through historical facts. ;-)

  

Painting and markings:

I was tempted to finish the model in Israeli markings, like Weaver’s, but then rather opted for a different route: I wanted to present the CM 194 in very normal operational colors, nothing exotic. After considering several options (Morocco, El Salvador, France) I eventually settled upon Belgium, and I went for the tactical three-tone scheme that was carried by the F-104 or Mirage V fighter bombers.

 

The pattern was adapted from an Alpha Jet export scheme and the colors were approximated from photo benchmarks. Many sources claim that the colors are the standard US SEA scheme, consisting of FS 34079, 34102 and 30219. However, the Dark Green is simply wrong (it’s a tone called FS 34064, and it’s a very dark olive drab), and the other colors come out much brighter than on typical US aircraft.

 

Consequently, FS 34102 was replaced by RAL 6003 (later even post-shaded with Humbrol 80, Grass Green!), while the tan tone is a mix of FS 30219 with Humbrol 94 (Desert Yellow). FS 34064 was created with a 1:1 mix of Humbrol 108 and 91 (later post-shaded with 75). The undersides were painted in FS 36495.

 

The cockpit interior became dark grey (Revell 77), while the landing struts and the wells were painted in aluminum; the covers’ inside received a finish in Chromate Yellow (Humbrol 81).

 

The dayglow markings on the tips of wings and the butterfly tail were created with decals sheet material, on top of which some paint (Humbrol 209) was added for a slight shading effect.

Generic decals in silver were also used to create the wing leading edges. National markings and warning stencils come from the scrap box.

Finally, the kit received a coat of matt acrylic varnish (Italeri).

  

Well, basically a simple conversion stunt, but it’s actually a complete kitbashing with – in my case – some considerable PSR work. However, the result is a very plausible, if not pretty, aircraft. From certain angles, the swept-wing Magister reminds me of the Alpha Jet (esp. the nose section, probably due to the pointed nose?), and the whole thing appears somehow bigger as it actually is. And I like the paint scheme: even though it’s camouflage, the dayglow markings and the bright insignia and stencils create a lively look.

Some background:

The Northrop Grumman-IAI F-24 is the latest reincarnation of the USAF "Lightweight Fighter Program" which dates back to the 1950ies and started with the development of Northrop's F-5 "Freedom Fighter".

 

The 1st generation F-5 became very successful in the export market and saw a long line of development, including the much more powerful F-5E "Tiger II" and the F-20 Tigershark (initially called F-5G). Northrop had high hopes for the F-20 in the international market; however, policy changes following Ronald Reagan's election meant the F-20 had to compete for sales against aircraft like the F-16, the USAF's latest fighter design (which was politically favored). The F-20 development program was eventually abandoned in 1986 after three prototypes had been built and a fourth partially completed.

 

But this was not the end for Northrop’s Lightweight Fighter. In the early 1980s, two X-29As experimental aircraft were built by Grumman from two existing Northrop F-5A Freedom Fighter airframes. The Grumman X-29 was a testbed for forward-swept wings, canard control surfaces, and other novel aircraft technologies. The aerodynamic instability of this arrangement increased agility but required the use of computerized fly-by-wire control. Composite materials were used to control the aeroelastic divergent twisting experienced by forward-swept wings, also reducing the weight. The NASA test program continued from 1984 to 1991 and the X-29s flew 242 times, gathering valuable data and breaking ground for new aerodynamic technologies of 4th and 5th generation fighters.

 

Even though no service aircraft directly evolved from the X-29, its innovative FBW system as well as the new material technologies also opened the door for an updated F-20 far beyond the 1990ies. It became clear that ever expensive and complex aircraft could not be the answer to modern, asymmetrical warfare in remote corners of the world, with exploding development costs and just a limited number of aircraft in service that could not generate true economies of scale, esp. when their state-of-the-art design would not permit any export.

Anyway, a global market for simpler fighter aircraft was there, as 1st generation F-16s as well as the worldwide, aging F-5E fleet and types of Soviet/Russian origin like the MiG-29 provided the need for a modern, yet light and economical jet fighter. Contemporary types like the Indian HAL Tejas, the Swedish Saab Gripen, the French Dassault Rafale and the Pakistani/Chinese FC-1/JF-17 ”Thunder” proved this trend among 4th - 4.5th generation fighter aircraft.

 

Northrop Grumman (Northrop bought Grumman in 1994) initiated studies and basic design work on a respective New Lightweight Fighter (NLF) as a private venture in 1995. Work on the NLF started at a slow pace, as the company was busy with re-structuring.

The idea of an updated lightweight fighter was fueled by another source, too: Israel. In 1998 IAI started looking in the USA for a development partner for a new, light fighter that would replace its obsolete Kfir fleet and partly relieve its F-16 and F-15 fleet from interception tasks. The domestic project for that role, the IAI Lavi, had been stillborn, but lots of its avionics and research were still at hand and waited for an airframe for completion.

The new aircraft for the IAF was to be superior to the MiG-29, at least on par with the F-16C/D, but easier to maintain, smaller and overall cheaper. Since the performance profiles appeared to be similar to what Northrop Grumman was developing under the NLF label, the US company eventually teamed up with IAI in 2000 and both started the mutual project "Namer" (=נמר, “Tiger” in Hebrew), which eventually lead to the F-24 I for the IAF which kept its project name for service and to the USAF’s F-24A “Tigershark”.

 

The F-24, as the NLF, was based on the F-20 airframe, but outwardly showed only little family heritage, onle the forward fuselage around the cockpit reminds of the original F-5 design . Many aerodynamic details, e. g. the air intakes and air ducts, were taken over from the X-29, though, as the experimental aircraft and its components had been developed for extreme maneuvers and extra high agility. Nevertheless, the X-29's forward-swept wing was considered to be too exotic and fragile for a true service aircraft, but the F-24 was to feature an Active Aeroelastic Wing (AAW) system.

 

AAW Technology integrates wing aerodynamics, controls, and structure to harness and control wing aeroelastic twist at high speeds and dynamic pressures. By using multiple leading and trailing edge controls like "aerodynamic tabs", subtle amounts of aeroelastic twist can be controlled to provide large amounts of wing control power, while minimizing maneuver air loads at high wing strain conditions or aerodynamic drag at low wing strain conditions. This system was initially tested on the X-29 and later on the X-53 research aircraft, a modified F-18, until 2006.

 

Both USAF and IAF versions feature this state-of-the-art aerodynamic technology, but it is uncertain if other customers will receive it. While details concerning the F-24's system have not been published yet, it is assumed that its AAW is so effective that canard foreplanes could be omitted without sacrificing lift and maneuverability, and that drag is effectively minimized as the wing profile can be adjusted according to the aircraft’s speed, altitude, payload and mission – much like a VG wing, but without its clumsy and heavy swiveling mechanism which has to bear high g forces. As a result, the F-24 is, compared to the F-20, which could carry an external payload of about 3.5 tons, rumored to be able to carry up to 5 tons of ordnance.

 

The delta wing shape proved to be a perfect choice for the required surface and flap actuators inside of the wings, and it would also offer a very good compromise between lift and drag for a wide range of performance. Anyway, there was one price to pay: in order to keep the wing profile thin and simple, the F-24’s landing gear retracts into the lower fuselage, leaving the aircraft with a relatively narrow track.

 

Another major design factor for the outstanding performance of this rather small aircraft was weight reduction and structural integrity – combined with simplicity, ruggedness and a modular construction which would allow later upgrades. Instead of “going big” and expensive, the new F-24 was to create its performance through dedicated loss of weight, which was in some part also a compensation for the AAW system in the wings and its periphery.

 

Weight was saved wherever possible, e .g. a newly developed, lightweight M199A1 gatling gun. This 20mm cannon is a three-barreled, heavily modified version of the already “stripped” M61A2 gun in the USAF’s current F-18E and F-22. One of the novel features is a pneumatic drive instead of the traditional electric mechanism, what not only saves weight but also improves trigger response. The new gun weighs only a mere 65kg (the six-barreled M61A2 weighs 92kg, the original M61A1 112 kg), but still reaches a burst rate of fire of 1.800 RPM (about 800 RPM under cyclic fire, standard practice is to fire the cannon in 30 to 50-round bursts, though) and a muzzle velocity of 1.050 metres per second (3,450 ft/s) with a PGU-28/B round.

 

While the F-16 was and is still made from 80% aluminum alloys and only from 3% composites, the F-24 makes major use of carbon fiber and other lightweight materials, which make up about 40% of the aircraft’s structure, plus an increased share of Titanium and Magnesium alloys. As a consequence and through many other weight-saving measures like keeping stealth capabilities to a minimum (even though RAM was deliberately used and many details designed to have a natural low radar signature, resulting in modest radar cross-section (RCS) reductions), a single, relatively small engine, a fuel-efficient F404-GE-402 turbofan, is enough to make the F-24 a fast and very agile aircraft, coupled with a good range. The F-24’s thrust/weight ratio is considerably higher than 1, and later versions with a vectored thrust nozzle (see below) will take this level of agility even further – with the pilot becoming the limiting factor for the aircraft’s performance.

 

USAF and IAF F-24s are outfitted with Northrop Grumman's AN/APG-80 Active Electronically Scanned Array (AESA) radar, also used in the F-16 Block 60 aircraft. Other customers might only receive the AN/APG-68, making the F-24 comparable to the F-16C/D.

 

The first prototype, the YF-24, flew on 8th of March 2008, followed by two more aircraft plus a static airframe until summer 2010. In early 2011 the USAF placed an initial order of 101 aircraft (probably also to stir export sales – the earlier lightweight fighters from Northrop suffered from the fact that the manufacturer’s country would not use the aircraft in its own forces). These initial aircraft will replace older F-16 in the interceptor role, or free them for fighter bomber tasks. The USN and USMC also showed interest in the aircraft for their aggressor squadrons, for dissimilar air combat training. A two-seater, called the F-24B, is supposed to follow soon, too, and a later version for 2020 onwards, tentatively designated F-24C, is to feature an even stronger F404 engine and a 3D vectoring nozzle.

 

Israel is going to produce its own version domestically from late 2014 on, which will exclusively be used by the IAF. These aircraft will be outfitted with different avionics, built by Elta in Israel, and cater to national requirements which focus more on multi-purpose service, while the USAF focusses with its F-24A on aerial combat and interception tasks.

 

International interest for the F-24A is already there: in late 2013 Grumman stated that initial talks have been made with various countries, and potential export candidates from 2015 on are Taiwan, Singapore, Thailand, Finland, Norway, Australia and Japan.

The kit and its assembly:

A spontaneous project. This major kitbash was inspired by fellow user nighthunter at whatifmodelers.com, who came up with a profile of a mashed-up US fighter, created “out of boredom”. The original idea was called F-21C, and it was to be a domestic successor to the IAI Kfirs which had been used by the US as aggressor aircraft in USN and USMC service for a few years.

 

As a weird(?) coincidence I had many of the necessary ingredients for this fictional aircraft in store, even though some parts and details were later changed. This model here is an interpretation of the original design. The idea was spun further, and the available parts that finally went into the model also had some influence on design and background.

I thank nighthunter for sharing the early ideas, inviting me to take the design to the hardware stage (sort of…) and adapting my feedback into new design sketches, too, which, in return, inspired the model building process.

 

Well, what went into this thing? To cook up a F-24 à la Dizzyfugu you just need (all in 1:72):

● Fuselage from a Hasegawa X-29, including the cockpit and the landing gear

● Fin and nose cone from an Italeri F-16A

● Inner wings from a (vintage) Hasegawa MiG-21F

● Outer wings from a F-4 (probably a J, Hasegawa or Fujimi)

 

The wing construction deviates from nighthunter’s original idea. The favorite ingredients would have been F-16XL or simple Mirage III wings, but I found the composite wing to be more attractive and “different”. The big F-16XL wings, despite their benefit of a unique shape, might also have created scale/size problems with a F-20 style fuselage? So I built hybrid wings: The MiG-21 landing gear wells were filled with putty and the F-4 outer wings simply glued onto the MiG inner wing sections, which were simply cut down in span. It sounds like an unlikely combo, but these parts fit together almost perfectly! In order to hide the F-4 origins I modified them to carry wingtip launch rails, though, which were also part of nighthunter’s original design.

 

The AAW technology detail mentioned in the background came in handy as it explains the complicated wing shape and the fact that the landing gear retracts into the fuselage, not into the wings, which would have been more plausible… Anyway, there’s still room for a simpler export version, with Mirage III or Kfir C.2/7 wings, and maybe canards?

 

Using the X-29 as basis also made fitting the new wings onto the area-ruled fuselage pretty easy, as I could use the wing root parts from the X-29 to bridge the gap. The original, forward-swept wings were just cut away, and the remains used as consoles for the new hybrid delta wings. Took some SERIOUS putty work, but the result is IMHO fine.

 

The bigger/square X-29 air intakes were taken over, and they change the look of the aircraft, making it look less F-5-ish than a true F-20 fuselage. For the same reason I kept the large fairing at the fin base, combining it with a bigger F-16 tail, though, as a counter-balance to the new, bigger wings. Again, the F-16 fin was/is part of nighthunter’s idea, so the model stays true to the original concept.

 

For the same reason I omitted the original X-29 nose, which is rather pointy, sports vanes and a large sensor boom. The F-16 nose was a plausible choice, as the AN/APG-80 is also carried by late Fighting Falcons, and its shape fits well, too.

 

All around the hull, some small details like radar warning sensors, pitots and air scoops were added. Not really necessary, but such thing add IMHO to the overall impression of such a fictional aircraft beyond the prototype stage.

 

Cockpit and landing gear were taken OOB, I just added a pilot figure and slightly modified the seat.

 

The ordnance was puzzled together from the scrap box, the AIM-9Ls come from the same F-4 kit which donated its outer wings, the AIM-120s come from an Italeri NATO weapons kit. The drop tanks belong to an F-16.

  

Painting and markings:

At first I considered an F-24I in IAF markings, or even a Japanese aircraft, but then reverted to one of nighthunter’s initial, simple ideas: an USAF aircraft in the “Hill II” paint scheme (F-16 style), made up from three shades of gray (FS 36118, 36270 and 36375) with low-viz markings and stencils. Dutch/Turkish NF-5A/Bs in the “Hill II” scheme were used as design benchmarks, too. It’s a simple livery, but on this delta wing aircraft it looks pretty interesting. I used enamels, what I had at hand: Humbrol 127 and 126, and Modelmaster's 1723.

 

A light black ink wash was applied, in order to em,phasize the engraved panel lines, in contrast to that, panels were manually highlighted through dry-brushed, lighter shades of gray (Humbrol 27, 166 and 167).

 

“Hill II” also adds to a generic, realistic touch for this whif. Doing an exotic air force thing is rather easy, but creating a convincing whif for a huge military machinery like the USAF’s takes more subtlety, I think.

 

The cockpit was painted in medium Gray (Dark Gull Grey, FS 36231, Humbrol 140), as well as the radome. The landing gear and the air intakes were painted white. The radome was painted with Revell 47 and dry-brushed with Humbrol 140.

 

Decals were puzzled together from various USAF aircraft, including sheets from an Airfix F-117, an Italeri F-15E and even an Academy OV-10D.

  

Tadah: a hardware tribute to an idea, born from boredom - and the aircraft does not look even bad at all? What I wanted to achieve was to make the F-24 neither look like a F-20, nor a Saab Gripen clone, as the latter comes close in overall shape, size and design.

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!

 

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

 

Some background:

In December 1953, NATO Supreme Command issued specifications for a new light tactical support aircraft. European manufacturers were invited to submit their designs for this requested Light Weight Strike Fighter role. The G.91 was one contender and designed to this specification by the Italian engineer Giuseppe Gabrielli, hence the "G" designation.

 

The competition was intended to produce an aircraft that was light, small, expendable, equipped with basic weapons and avionics and capable of operating with minimal ground support. These specifications were developed for two reasons: the first was the nuclear threat to large air bases, many cheaper aircraft could be better dispersed, and the other was to counter the trend towards larger and more expensive aircraft.

 

The technical requirements were:

• 1,100 m (3,610 ft) takeoff distance over a 15 m (49 ft) obstacle

• Capability to operate from grass strips and roads

• Maximum speed of Mach 0.95

• Range of 280 km (170 mi) with 10 minutes over the target

• Armoured protection for the pilot and the fuel tanks

• 4 × 12.7 mm (.5 in) or 2 × 20 mm or 30 mm guns

• A maximum of 2,200 kg (4,850 lb) empty weight and 4,700 kg (10,360 lb) max. weight

 

The challenge of providing an engine that matched the requirements of lightness and power, reliability and ease of maintenance was solved by using the Bristol Siddeley Orpheus turbojet.

 

Project selections took 18 months to complete and the final selection of the three remaining competing designs was planned for late 1957. In September 1957, at the Centre d'Essais en Vol at Brétigny-sur-Orge, in France, the three rival aircraft types met for evaluation trials. During the trials the Italian aircraft performed impressively and, in January 1958, the Fiat G.91 was officially declared the winner.

 

Following a meeting of NATO Defence Ministers in April 1958 it was agreed that the G.91 would be the first NATO lightweight strike fighter. A production meeting was planned for May 1958 to discuss the production of the aircraft with financial support from the United States, the Americans would provide some of the finance for the French, German and Italian aircraft and pay for the Turkish aircraft. Other NATO states were supposed to buy the G.91, too., and the defence ministers reached agreement to order 50 aircraft for each country.

 

Given the large economic and commercial interests at stake, there was a certain amount of controversy surrounding this decision. After the loss of the G.91 prototype, the French government preferred to pursue development of the locally-designed Étendard. The British government similarly ignored the competition to concentrate on Hawker Hunter production for the same role.

The Italian government ordered the G.91 for the Italian Air Force before the results of the competition were known. An initial pre-production batch of machines would later go on to serve for many years with the Italian aerobatic team, the Frecce Tricolori as the G.91 PAN.

 

The G.91 was also considered by Austria, Norway, Spain, Greece, Switzerland, and even the United States Army, which briefly evaluated the type as a possible Forward Air Control aircraft before relinquishing all fixed-wing aircraft operations to the Air Force.

 

Spain bought the intended 50 aircraft (42 single seaters called G.91R/2, outfitting two fighter bomber squadrons, plus 8 trainers with tandem seats, comparable with the Italian G.91T/1 trainers), which were produced in Italy from early 1961 onwards and became operational with the Ejército del Aire in late 1962, replacing the F-86 and HA-220 Super Saetas in the ground attack/CAS role.

 

The G.91R/2 was a hybrid between the simple Italian G.91R/1 and the later, more sophisticated G.91R/4 for Greece and Turkey. It used the R/1's airframe with the modified nose housing three cameras, but already had four underwing hardpoints, structural reinforcements and improved avionics, including a Doppler radar and a revised instrumentation that was also introduced with the Italian R/1A.

 

The G.91 in Spanish service was already phased out from the mid 70ies onwards and completely retired in 1986, being replaced by F-5 and Mirage F.1.

The kit and its assembly:

Second entry for the "1 Week group Build" at whatifmodelers.com, since my first model was finished in just three days... This one struck me recently when I browsed through the F-5 book of the "Planes and Pilots" series, and came across the Spanish machines. What if Spain had bought the G.91...?

 

The resulting aircraft would surely have looked pretty in the three-tone "Small Asia" paint scheme, so the idea landed on the list and now entered the hardware stage.

 

...not until I got hands on a G.91 kit. Not easy, at least if you do not want to sink a fortune. I was lucky to find a pair of Airfix G.91s - from Japanese production, the boxes are dated 1981! And the kit is accordingly rather basic, especially anything concerning the interior is primitive, the wheels are a joke and the ordnance better ignored.

 

However, the fuselage lines are not bad, and since I had some leftover sprues from the more modern Revell G.91 in store I decided to pimp the Airfix kit with some donation parts and build an Ejércite del Aire whif.

 

It's not a true kitbashing, but a lot of Revell parts went into the vintage Airfix kit:

• The cockpit tub (which includes an upper wall for the air intake) was implanted

• The ejection seat and the dashboard, too

• An improvised jet nozzle was added - the Airfix kit just offers a bare hole(!)

• From the landing gear only the main struts were taken

• Even the landing gear covers were taken from the Revell kit

• The outer pylons are donations, too, while the inner ones were modified

• Ordnance is new, too, all from the spares box

 

The kit needed some putty work, but fit was surprisingly good.

  

Painting and markings:

Well, Spain is the theme and so I gave this Gina a "typical" livery, borrowed from export F-5s (e .g. for Spain, Iran, Jordania), the “Small Asia” paint scheme.

As basic colors I used Humbrol 74 (Linen), 29 (RAF Dark Earth) and 116 (FS34079), with pale grey undersides in Humbrol 129 (FS36440). The landing gear, its wells and the air intake were painted in Aluminum (Modelmaster), while the cockpit was kept in Dark Sea Grey (Humbrol 164) with a light blue dashboard - confirmed by real life pics.

 

As per usual the kit received a light black ink wash, light panel shading (also adding to a sun-bleached look) and some dry painting with light grey. No OOB decal was and could be used - 35 years took their toll!

 

Anyway, the decals come primarily from a Heller Mirage III, as well as some additional stencils e .g. from a BAC Lightning (Xtradecal sheet) and many red stripes or the camera ports, which were cut from TL Modellbau decal stripes.

 

Soot/exhaust stains were created with grinded graphite and around the nozzle and the gun ports. Finally, everything was sealed under a coat of matt acrylic varnish.

 

This Hispanic Gina is not a great piece of work, but the paint scheme changes IMHO the total look of the small aircraft, very different from what you usually see? And it's a second proud addition to whatifmodelers.com's "1 Week Group Build", created in the leftover five day timeframe after the first whif kit.

 

And does anybody doubt that Spain flew the G.91...?

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 wodks 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 tried to raise the OV-10 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. The front wheel retracts backwards now, but this looks quite plausible, thanks to the additional space under the cockpit tub, which also made an ammuntion belt supply for the gun believable.

To enhance the menacing look I gave the model a fixed refuleing 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 dipenesers 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 a Hasegawa USAF weapon set, representing the state-of-the-art of aerial defence. 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-4 and -19 missile pods on the stub wings were taken from the OV-10 kit.

 

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:

hanksnet.com/images/as_p2.jpg

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.

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...! ;)

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:

The VF-1 was developed by Stonewell/Bellcom/Shinnakasu for the U.N. Spacy by using alien Overtechnology obtained from the SDF-1 Macross alien spaceship. Its production was preceded by an aerodynamic proving version of its airframe, the VF-X. Unlike all later VF vehicles, the VF-X was strictly a jet aircraft, built to demonstrate that a jet fighter with the features necessary to convert to Battroid mode was aerodynamically feasible. After the VF-X's testing was finished, an advanced concept atmospheric-only prototype, the VF-0 Phoenix, was flight-tested from 2005 to 2007 and briefly served as an active-duty fighter from 2007 to the VF-1's rollout in late 2008, while the bugs were being worked out of the full-up VF-1 prototype (VF-X-1).

 

The space-capable VF-1's combat debut was on February 7, 2009, during the Battle of South Ataria Island - the first battle of Space War I - and remained the mainstay fighter of the U.N. Spacy for the entire conflict. Introduced in 2008, the VF-1 would be out of frontline service just five years later, though.

 

The VF-1 proved to be an extremely capable craft, successfully combating a variety of Zentraedi mecha even in most sorties which saw UN Spacy forces significantly outnumbered. The versatility of the Valkyrie design enabled the variable fighter to act as both large-scale infantry and as air/space superiority fighter. The signature skills of U.N. Spacy ace pilot Maximilian Jenius exemplified the effectiveness of the variable systems as he near-constantly transformed the Valkyrie in battle to seize advantages of each mode as combat conditions changed from moment to moment.

 

The basic VF-1 was deployed in four minor variants (designated A, D, J, and S) and its success was increased by continued development of various enhancements including the GBP-1S "Armored" Valkyrie, FAST Pack "Super" Valkyrie and the additional RÖ-X2 heavy cannon pack weapon system for the VF-1S for additional firepower.

The FAST Pack system was designed to enhance the VF-1 Valkyrie variable fighter, and the initial V1.0 came in the form of conformal pallets that could be attached to the fighter’s leg flanks for additional fuel – primarily for Long Range Interdiction tasks in atmospheric environment. Later FAST Packs were designed for space operations.

 

The following FAST Pack 2.0 system featured two 120.000 kg class P&W+EF-2001 booster thrusters (mounted on the dorsal section of the VF-1) and two CTB-04 conformal propellant/coolant tanks (mounted on the leg/engines), since the VF-1's internal tanks could not carry enough propellant to achieve a stable orbit from Earth bases and needed the help of a booster pack to reach Low Earth Orbit. Anyway, the FAST Pack 2.0 wasn't adapted for atmospheric use, due to its impact on a Valkyrie's aerodynamics and its weight; as such, it needed to be discarded before atmospheric entry.

Included in the FAST Pack boosters and conformal tanks were six high-maneuverability vernier thrusters and two low-thrust vernier thrusters beneath multipurpose hook/handles in two dorsal-mounted NP-BP-01, as well as ten more high-maneuverability vernier thrusters and two low-thrust vernier thrusters beneath multipurpose hook/handles in the two leg/engine-mounted NP-FB-01 systems.

Granting the VF-1 a significantly increased weapons payload as well as greater fuel and thrust, Shinnakasu Heavy Industry's FAST Pack system 2.0 was in every way a major success in space combat. The first VF-1 equipped with FAST Packs was deployed in January 2010 for an interception mission.

Following first operational deployment and its effectiveness, the FAST Pack system was embraced enthusiastically by the U.N. Spacy and found wide use. By February 2010, there were already over 300+ so-called "Super Valkyries" stationed onboard the SDF-1 Macross alone.

 

After the end of Space War I, the VF-1 continued to be manufactured both in the Sol system and throughout the UNG space colonies. Although the VF-1 would eventually be replaced as the primary Variable Fighter of the U.N. Spacy by the more capable, but also much bigger, VF-4 Lightning III in 2020, a long service record and continued production after the war proved the lasting worth of the design.

 

The VF-1 was without doubt the most recognizable variable fighter of Space War I and was seen as a vibrant symbol of the U.N. Spacy even into the first year of the New Era 0001 in 2013. At the end of 2015 the final rollout of the VF-1 was celebrated at a special ceremony, commemorating this most famous of variable fighters. The VF-1 Valkryie was built from 2006 to 2013 with a total production of 5,459 VF-1 variable fighters with several variants (VF-1A = 5,093, VF-1D = 85, VF-1J = 49, VF-1S = 30, VF-1G = 12, VE-1 = 122, VT-1 = 68)

 

However, the fighter remained active in many second line units and continued to show its worthiness years later, e. g. through Milia Jenius who would use her old VF-1 fighter in defense of the colonization fleet - 35 years after the type's service introduction.

The model and its assembly:

This is a major kit conversion, or better a kitbashing with major scratch work involved. By the time I built this model, there were no convincing 1:100 kits of the so-called "Super / Strike Valkyries" around. These VF-1s carry rocket boosters for non-atmospherical use, so-called FAST packages ("Fuel And Sensor Trays"). However, parts for these space operation packages are included in some ARII Battroid kits.

 

This is the second of such conversions I did on the basis of a 1:100 Bandai (ex Arii) Gerwalk Valkyrie model, with additional leftover pieces from Super Valkyrie kits in Battroid mode and even from vintage Imai transformable kits.

 

The legs in retracted position were completely built through kitbashing, since the FAST packages would hardly fit under the body. The folded arms between the legs were improvised and heavily tailored to fit into the narrow space between the legs as good as possible. Real arm parts would not fit at all!

 

The "UUM-7" rocket launchers with 5 x 3 HMM-01missiles each were built from scratch. other added details include a pilot figure and better cockpit interior parts, plus some other details like antennae that the simple, original kits lack.

 

Painting and markings:

The color scheme is based on the standard VF-1A livery, even though I used a lighter tan (RAF "Hemp", B.S. 4800/10B21, e .g. used on Nimrod sea patrol aircrafts or VC-10 tankers - Humbrol 168) instead of brown. The lighter contrast areas were painted in ivory (Humbrol 41) instead of pure white, the FAST packs received a grey finish (FS 36081, Humbrol 32).

 

What's a bit special about the colored details of this semi-fictional Valkyrie is that the squadron insignia is original Japanese: The panda with the red lightning is the emblem of the 203rd hikotai, a real world JASDF fighter squadron that used to fly F-86 Sabre and F-104 Starfighters – with some fantasy, you can read the "203" in the lightning's outline! The kit's idea was to show what a machine from such a "real" squadron might look like if it was (still) existent in the Macross universe?

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.

The kit and its assembly:

A major kitbashing project which I had on my idea list for a long time and its main ingredients/body donors already stashed away – but, as with many rather intimidating builds, it takes some external motivation to finally tackle the idea and bring it into hardware form. This came in August 2020 with the “Prototypes” group build at whatifmodellers.com, even though is still took some time to find the courage and mojo to start.

 

The original inspiration was the idea of a stealthy successor for the A-10, or a kind of more modern A-7 as an alternative to the omnipresent (and rather boring, IMHO) F-35. An early “ingredient” became the fuselage of a Zvezda Ka-58 stealth helicopter kit – I liked the edgy shape, the crocodile-like silhouette and the spacious side-by-side cockpit. Adding wings, however, was more challenging, and I remembered a 1:200 B-2A which I had turned into a light Swedish 1:72 attack stealth aircraft. Why not use another B-2 for the wings and the engines, but this time a bigger 1:144 model that would better match the quite bulbous Ka-58 fuselage? This donor became an Italeri kit.

 

Work started with the fuselage: the Ka-58’s engine and gearbox hump had to go first and a generous, new dorsal section had to be scratched with 1mm styrene sheet and some PSR. The cockpit and its glazing could be retained and were taken OOB. Under the nose, the Ka-58’s gun turret was omitted and a scratched front landing gear well was implanted instead.

 

The wings consist of the B-2 model; the lower “fuselage half” had its front end cut away, then the upper fuselage half of the Ka-58 was used as benchmark to cut the B-2’s upper wing/body part in two outer wing panels. Once these elements had been glued together, the Ka-58’s lower nose and tail section were tailored to match the B-2 parts. The B-2 engine bays were taken OOB and mounted next, so that the A-14’s basic hull was complete and the first major PSR session could start. Blending the parts into each other turned out to be a tedious process, since some 2-3 mm wide gaps had to be filled.

 

Once the basic BWP pack had been finished, I added the fins. These were taken from an 1:72 F-117 kit (IIRC from Italeri), which I had bought in a lot many moons ago. The fins were just adapted at their base to match the tail sting slope, and they were mounted in a 45° angle. This looks very F-117ish but was IMHO the most plausible solution.

 

Now that the overall length of the aircraft was defined, I could work on the final major assembly part: the wing tips. The 1:144 B-2 came with separate wing tip sections, but they proved to be much too long for the Squatina. After some trials I reduced their length by more than half, so that the B-2’s jagged wing trailing edge was kept. The result looks quite natural, even though blending the cut wing tips to the BWB turned out to be a PSR nightmare because their thickness reduces gently towards the tip – since I took out a good part of the inner section, the resulting step had to be sanded away and hidden with more PSR.

 

Detail work started next, including the cockpit glazing, the bomb bay (the B-2 kit comes with one of its bays open, and I kept this detail and modified the interior) and the landing gear, the latter was taken from the F-117 donor bank and fitted surprisingly well.

Some sensors were added, too, including a flat glass panel on the nose tip and a triangular IRST fairing under the nose, next to the landing gear well.

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.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

  

The Fiat Macchi C.170 Brezza ("Gust of wind") was a single-seat biplane fighter which served primarily in Italy's Regia Aeronautica before and in the early stages of World War II. The aircraft was produced by the Varese firm, and entered service, in smaller numbers, with the air forces of Italy, Austria and Hungary.

 

In spite of the biplane configuration, the C.170 was a modern, 'sleek-looking' design based around a strong steel and alloy frame incorporating a NACA cowling housing the radial engine, with fairings for the fixed main landing gear. The C.170's upper wing was slightly larger than its lower wing, carried only by six struts and a few bracing wires. Only the upper wing featured ailerons while the lower wing carried large flaps. Although it looked slightly outdated, the aircraft proved exceptionally agile thanks to its very low wing loading and a powerful, responsive engine.

 

Power was provided by a 650 kW (870 hp) Fiat A.74 14 cylinder radial engine, which also drove the contemporary Fiat CR.32 fighter. With the "direttiva" (Air Ministry Specific) of 1932, Italian industrial leaders had been instructed to concentrate solely on radial engines for fighters, due to their better reliability. The A.74 was actually a re-design of the American Pratt & Whitney R-1830 SC-4 Twin Wasp made by engineers Tranquillo Zerbi and Antonio Fessia, and in the C.170 it was geared to drive a metal three-blade Fiat-Hamilton Standard 3D.41-1 propeller of 2.9 m (9.5 ft) diameter. This allowed an impressive top speed of 441 km/h (272 mph) at 6.500 m (20.000 ft), and 342 km/h (213 mph) at ground level.

 

The first C.170 prototype flew on 24 December 1934 in Lonate Pozzolo, Varese, with Macchi Chief Test Pilot Giuseppe Burei at the controls. It was followed by the second prototype early the next year, which flew with an armored headrest and fairing in place (the C.170 lacked any further armor!) and other minor changes that were incorporated for serial production.

Despite Macchi’s proposal for a closed cockpit canopy the cockpit remained open – Italian pilots were rather conservative. Additional protection was introduced through armored side panels, though, which would protect the pilot’s shoulders. Radio equipment was also not included, as in many other Italian fighter aircraft.

 

During evaluation in early 1935 the C.170 was tested against the Fiat CR.42 and the Caproni Ca.165 biplane fighters, and was judged to be on par with the CR.42, although the Ca.165 was a more modern design which boasted a higher speed at the cost of maneuverability. An initial order of 99 C.170 for Italy's Regia Aeronautica was placed to Macchi factory in summer 1935, followed by foreign interest and order options from Austria, Belgium and Spain.

 

Anyway, what looked like a prosperous design was soon rendered obsolete: Following the end of Italy's campaigns in East Africa, a program was started to completely re-equip the Regia Aeronautica with a new interceptor aircraft of modern design. The 10 February 1936 specifications called for an aircraft powered by a single radial engine, with a top speed of 500 km/h, climb rate at 6,000 meters of 5 minutes, with a flight endurance of two hours, and armed with a single (later increased to two) 12.7 mm (0.5 in) machine gun. That was more or less the premature end for the C.170, as Macchi and other manufacturers quickly turned to more modern monoplane designs.

 

Therefore, orders and production of the Macchi Brezza remained limited. Beyond the original 99 aircraft for the Regia Aeronautica only 24 further C.170s were delivered. These aircraft went in spring 1936 to Austria to equip Jagdgeschwader II at Wiener Neustadt. Immediately after their delivery the Brezza fighters were retro-fitted with radio equipment, recognizable through the antenna installation on the headrest fairing. The potential orders from Belgium and Spain were soon cancelled, due to political tensions.

 

As a side note, the Austrian C.170s fighters were the first aircraft to sport the new national emblem, which had been the result of a competition and won by flight engineer Rosner from the Graz-Thalerhof base. The white, equilateral triangle with the point facing downwards in a red disc was a completely new design and had (other than the flag or coats of arms) no prior basis.

 

The C.170s' career in Austrian service was short, though: in March 1938 the Austrian units were absorbed into the Luftwaffe, and after a brief period the aircraft were handed over to Hungary where they were used for training purposes.

 

Although an obsolete design, it proved to be robust, durable and effective especially in severe conditions. In spring 1943, surviving C.170s were rounded up from training schools and delivered to night ground attack units operating on the Eastern Front. The C.170 was used to conduct night harassment sorties on the Eastern Front until September 1944, when the units were disbanded, due to a lack of serviceable airframes and spare parts.

The kit and its assembly

Inspiration for this little, whiffy biplane came when I posted a pic of an Austrian Ju 86 bomber as a reply/ suggestion to a fellow modeler's (NARSES2) search at whatifmodelers.com for “something” to make from a Gloster Gladiator.

When I looked at the paint scheme a second time I remembered that I still had some Austrian roundels in stock, as well some very old biplane spare parts... hmmm.

 

Biplanes are tricky to build, even OOB, and kitbashing this kind of whif would not make things easier. Anyway, I love such challenges, and the potential outcome would surely look nice, if not exotic, so I decided to tackle the project.

 

Basically, the following donation ingredients went into it:

● Fuselage, engine, cockpit/pilot and tail from a Revell Macchi C.200 "Saetta"

● Upper wing from a Matchbox Gloster "Gladiator"

● Lower wings from a Matchbox SBC "Helldiver"

● Wheels from a Matchbox Hs 126 (shortened)

 

Pretty straightforward, but even though it would be a small aircraft model, it would come with two big challenges: mounting the lower wings and shaping the resulting, gaping belly, and the custom-made struts and wirings for the upper wing.

 

Work started with the Macchi C.200’s fuselage, which was built OOB - just without the wing, which is a single part, different pilot (the included one is a pygmy!) and with a free spinning metal axis for the propeller.

 

The wing installation started with the lower wings. I glued the Helldiver wings onto the C.200 fuselage, so that the wings' trailing edge would match the C.200's wing root ends. From that, a floor plate was fitted under the fuselage and any excessive material removed, the gaps filled with lumps of 2C putty. That moved the lower wing's roots backwards, creating space at the lower forward fuselage for the new landing gear.

 

The latter was taken from a vintage Matchbox Hs 126 reconnaissance aircraft - probably 25, if 30 years old... Size was O.K., but the struts had to shortened by about 5mm, as thge HS 126 is a much bigger/longer aircraft than the C.200. A cut was made just above the wheel spats, material taken out, and the separate parts were glued back together again.

 

With the lower wings in place I started building strut supports for the upper wing from styrene strips - tricky and needs patience, but effective. I started with the outer supports, carving something SBC-style from styrene. These were glued into place, slightly canted outwards, and their length/height adapted to the upper wing’s position.

When this was settled, the upper Gladiator wing was glued into place. After a thorough drying period the short fuselage supports in front of the cockpit – again, styrene strips – were inserted into the gap. This allowed an individual lengthening, and was easier than expected, with a stable result.

After having the upper wing glued in place I added some wiring, made from heated and pulled-out styrene sprues. This not only enhances the kit's look, it also (just like in real life) improves rigidity of the model. Also a tedious task, but IMHO worth the effort. I tried thin wire, nylon strings and sewing yarn for this job, but finally the styrene solution is what worked best for me.

The exhaust installation had also to be modified: the new Hs 126 struts with spats would have been where the original C.200’s hot exhaust gases would have gone, so I added new exhaust pipes that would go between the new legs.

Other small added details included, among others, a pitot on a wing strut, a visor in front of the cockpit, a radio antenna, a ladder made from wire.

  

Painting and markings:

I would not call the Austrian 3+1-tone pre-WWII-scheme spectacular, but the colors are unique. My scheme is based on an Austrian Ju 86 bomber from 1938, so it fits into the intended time frame.

 

The colors were puzzled together from various sources and are subjective guesstimates:

● A pale, yellow-ish beige (Humbrol 74, ‘Linen’, out of production)

● A rather brownish green (Testors 1711, ‘Olive Drab’, FS 34087)

● A dark green with a yellow-ish hue (Humbrol 116, ‘US Dark Green’ FS 34079)

● Light blue for the undersides (Humbrol 65, ‘Aircraft Blue’, RLM 65)

 

In order to add some details I painted the area behind the engine cowling in aluminum. The respective part under the fuselage, where the exhaust gases would pass, was painted in Steel – both Testors Metallizers.

The interior surfaces were painted in a neutral Grey – but with the engine and the pilot in place you cannot see anything of that at all.

Markings are minimal: the Austrian roundels come from a TL Decals aftermarket sheet, the flag on the rudder was laid out with red paint (a mix of Humbrol 19 and 60), the white bar is a decal. The tactical code is fictional, puzzled together from single digits in various sizes (also from TL Modellbau sheets). The original documents how purely black fuselage codes, but I found these hard to read. So I chose digits with a white rim (actually, these belong to modern German Luftwaffe tactical codes in 1:32), which improve contrast a little.

The kit received a thin black ink wash and some shading/dry-painting with lighter basic tones (Humbrol 103, 155, Model Master 2138,‘Israeli Armor Sand Grey’, and Humbrol 122). After decal application, another turn with overall Hemp and Light Grey was done in order to fade contrast and to emphasize the surface structure. The wires were also painted, but only with thinned black ink and a VERY soft brush.

 

Finally, everything was sealed under a spray coat of matt acrylic varnish.

Voilà, and done in just about a week!

Some background:

The Hawker Cyclone was an evolutionary successor to the successful Hawker Typhoon and Tempest fighters and fighter-bombers of the Second World War. The Cyclone's design process was initiated in September 1942 by Sydney Camm, one of Hawker's foremost aircraft designers, to meet the Royal Air Force’s requirement for a lightweight Tempest Mk.II and V replacement.

The project, tentatively designated Tempest Mk. VIII, was formalised in January 1943 when the Air Ministry issued Specification F.2/42 around the "Tempest Light Fighter".This was followed up by Specification F.2/43, issued in May 1943, which required a high rate of climb of not less than 4,500 ft/min (23 m/s) from ground level to 20,000 feet (6,096 m), good fighting manoeu rability and a maximum speed of at least 450 mph (724 km/h) at 22,000 feet (6,705 m). The armament was to be four 20mm Hispano V cannon with a total capacity of 600 rounds, plus the capability of carrying two bombs each up to 1,000 pounds (454 kg). In April 1943, Hawker had also received Specification N.7/43 from the Admiralty, who sought a navalized version of the developing aircraft, what eventually led to the Hawker Sea Fury, which was a completely new aircraft, which only shared the general outlines of the Tempest.

 

The Royal Air Force was looking for a quicker solution, and Camm started working on a new laminar flow wing, which would further improve the Tempest’s speed. Further refinements were done to other aerodynamic components, too, like the radiator, since the Tempest V’s liquid-cooled Napier Sabre engine was to be used. After some experiments with new arrangements, an annular radiator directly behind the propeller was chosen – certainly inspired by fast German aircraft like the Fw 190D and developed by Napier.

 

A total of three prototypes were ordered; the first one was powered by a Napier Sabre IIA liquid-cooled H-24 sleeve-valve engine, generating 2,180 hp (1,625 kW), but the second and any following aircraft carried the more powerful Sabre V with 2,340 hp, driving a Rotol four-blade propeller. Later aircraft were even to carry the Napier Sabre VII, which was capable of developing 3,400–4,000 hp (2,535–2,983 kW) and pushing the top speed to 485 mph (780 km/h) and more. The third airframe was just a static test structure. However, since the differences between the Tempest and the new aircraft had become almost as big as to its predecessor, the Typhoon, the new type received its own name Cyclone.

 

The first Cyclone Mk. I to fly, on 30 August 1944, was NV950, and it became clear soon that the modifications would improve the Cyclone’s top speed vs. the Tempest by almost 30 mph (50 km/h), but the new components would also require a longer testing period than expected. The annular radiator frequently failed and overheated, and the new, slender wings caused directional stability problems so that the complete tail section had to be re-designed. This troubling phase took more than 6 months, so that eventual service aircraft would only be ready in mid-1945 – too late for any serious impact in the conflict.

 

However, since the Hawker Fury, the land-based variant of the Sea Fury, which had been developed from the Tempest for the Royal Navy in parallel, had been cancelled, the Royal Air Force still ordered 150 Cyclone fighters (F Mk. I), of which one third would also carry cameras and other reconnaissance equipment (as Cyclone FR Mk.II). Due to the end of hostilities in late 1945, this order immediately lost priority. Consequently, the first production Cyclone fighters were delivered in summer 1946 – and in the meantime, jet fighters had rendered the piston-powered fighters obsolete, at least in RAF service. As a consequence, all Cyclones were handed over to friendly Commonwealth nations and their nascent air forces, e. g. India, Thailand or Burma. India received its first Cyclones in late 1947, just when the Kashmir conflict with Pakistan entered a hot phase. The machines became quickly involved in this conflict from early 1948 onwards.

 

Cyclones played an important role in the strikes against hostiles at Pir Badesar and the dominating Pir Kalewa. The taking of Ramgarh fort and Pt. 6944 on the west flank of Bhimbar Gali was to be a classic close support action with Indian forces carrying out a final bayonet charge against the enemy trenches whilst RIAF Cyclones and Tempests strafed and rocketed the trenches at close quarters. On a chance reconnaissance, enemy airfields were located at Gilgit and 40 NMs south, at Chilas. Cyclones flew several strikes against the landing strips in Oct and Nov 48, cratering & damaging both and destroying several hangars, barracks and radio installations. This attack destroyed Pakistani plans to build an offensive air capability in the North. Already, with Tempests and Cyclones prowling the valleys, Pakistani re-supply by Dakotas had been limited to hazardous night flying through the valleys.

 

After the end of hostilities in late 1948 and the ensuing independence, the Cyclone squadrons settled into their peace time stations. However, constant engine troubles (particularly the radiator) continued to claim aircraft and lives and the skill required to land the Cyclone because of its high approach speed continued to cause several write offs. The arrival of the jet-engined Vampire were the first signs of the Cyclone’s demise. As the IAF began a rapid expansion to an all jet force, several Tempest and Cyclone squadrons began converting to Vampires, 7 Squadron being the first in Dec 49. By this time it had already been decided that the piston-engine fighters would be relegated to the fighter lead-in role to train pilots for the new jet fighters. A conversion training flight was set up at Ambala in Sep 49 with Spitfire T Mk IXs, XVIIIs and Tempests to provide 16 hrs/six weeks of supervised Tempest training. This unit eventually moved to Hakimpet two years later and operated till the end of 1952. Some Cyclone FR Mk. IIs remained in front line service until 1954, though.

The kit and its assembly:

Another episode in the series “Things to make and do with Supermarine Attacker wings”. And what started as a simple switch of wings eventually turned into a major kitbashing, since the model evolved from a modded Tempest into something more complex and conclusive.

 

The initial spark was the idea of a Hawker alternative to Supermarine’s Spiteful and Seafang developments – especially with their slender laminar flow wings. Wouldn’t a Hawker alternative make sense?

 

Said and done, I dug out a NOVO Attacker kit and a Matchbox Tempest, and started measuring – and the wing transplantation appeared feasible! I made the cut on the Tempest wing just outside of the oil cooler, and the Attacker wings were then attached to these stubs – after some gaps for the landing gear wells had been cut into the massive lower wing halves. The stunt went more smoothly than expected, the only cosmetic flaw is that the guns went pretty far outboard, but that’s negligible.

 

But the different wings were not enough. I had recently seen in a book a picture of a Tempest (NV 768) with an experimental annular radiator for the Sabre engine (looking like a streamlined Tempest II), and wondered if this arrangement would have been the aerodynamically more efficient solution than the bulbous chin radiator of the Tempest V and VI? I decided to integrate this feature into my build, too, even though not as a copy of the real-world arrangement. The whole nose section, even though based on the OOB Mk. V nose, was scratched and re-sculpted with lots of putty. The radiator intake comes from a FROG He 219, with the front end opened and a fan from a Matchbox Fw 190 placed inside, as well as a styrene tube for the new propeller. The latter was scratched, too, from a Matchbox He 70 spinner and single blades from an Italeri F4U, plus a metal axis. The exhaust stubs were taken OOB, but their attachment slits had to be re-engraved into the new and almost massive nose section.

 

Once the wings and the nose became more concrete, I found that the Tempest’s original rounded tail surfaces would not match with the new, square wings. Therefore I replaced the stabilizers with donations from a Heller F-84G and modified the fin with a new, square tip (from an Intech Fw 190D) and got rid of the fin fillet – both just small modifications, but they change the Tempest’s profile thoroughly.

 

In order to underline the aircraft’s new, sleek lines, I left away any ordnance – but instead I added some camera fairings: one under the rear fuselage or a pair of vertical/oblique cameras, and another camera window portside for a horizontal camera. The openings were drilled, and, after painting, the kit the camera windows were created with Humbrol Clearfix.

  

Painting and markings:

Somehow I thought that this aircraft had to carry Indian markings – and I had a set of standard Chakra Wheels from the late Forties period in my stash. The camouflage is, typical for early IAF machines of British origin, RAF standard, with Dark Green and Ocean Grey from above and Medium Sea Grey from below. I just used the more brownish pst-war RAF Dark Green tone (Humbrol 163), coupled with the rather light Ocean Grey from Modelmaster (2057). The underside became Humbrol 165. All interior surfaces were painted with RAF Interior Green, nothing fancy. The only colorful addition is the saffron-colored spinner, in an attempt to match the fin flash’s tone.

 

As a standard measure, the kit received a black ink wash and some panel post-shading with lighter tones – only subtly, since the machine was not to look too weathered and beaten, just used from its Kashmir involvements.

 

The national markings come from a Printscale Airspeed Oxford sheet, the tactical code with alternating white and black letters, depending on the underground (the sky fuselage band comes from a Matchbox Brewster Buffalo), was puzzled together from single letters from TL Modellbau – both seen on different contemporary RIAF aircraft.

As another, small individual detail I gave the machine a tactical code letter on the fuselage, and the small tiger emblems under the cockpit were home-printed from the official IAF No. 1 Squadron badge.

  

Despite the massive modifications this one is a relatively subtle result, all the changes become only visible at a second glance. A sleek aircraft, and from certain angley the Cyclone looks like an A-1 Skyraider on a diet?

 

Trash freighter.

 

Picked up this tiny little Bandai, so detailed, so cheap! Anyway the parts are fun to play around with. Some interesting ship designs resulted.

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:

The Hawker Cyclone was an evolutionary successor to the successful Hawker Typhoon and Tempest fighters and fighter-bombers of the Second World War. The Cyclone's design process was initiated in September 1942 by Sydney Camm, one of Hawker's foremost aircraft designers, to meet the Royal Air Force’s requirement for a lightweight Tempest Mk.II and V replacement.

The project, tentatively designated Tempest Mk. VIII, was formalised in January 1943 when the Air Ministry issued Specification F.2/42 around the "Tempest Light Fighter".This was followed up by Specification F.2/43, issued in May 1943, which required a high rate of climb of not less than 4,500 ft/min (23 m/s) from ground level to 20,000 feet (6,096 m), good fighting manoeu rability and a maximum speed of at least 450 mph (724 km/h) at 22,000 feet (6,705 m). The armament was to be four 20mm Hispano V cannon with a total capacity of 600 rounds, plus the capability of carrying two bombs each up to 1,000 pounds (454 kg). In April 1943, Hawker had also received Specification N.7/43 from the Admiralty, who sought a navalized version of the developing aircraft, what eventually led to the Hawker Sea Fury, which was a completely new aircraft, which only shared the general outlines of the Tempest.

 

The Royal Air Force was looking for a quicker solution, and Camm started working on a new laminar flow wing, which would further improve the Tempest’s speed. Further refinements were done to other aerodynamic components, too, like the radiator, since the Tempest V’s liquid-cooled Napier Sabre engine was to be used. After some experiments with new arrangements, an annular radiator directly behind the propeller was chosen – certainly inspired by fast German aircraft like the Fw 190D and developed by Napier.

 

A total of three prototypes were ordered; the first one was powered by a Napier Sabre IIA liquid-cooled H-24 sleeve-valve engine, generating 2,180 hp (1,625 kW), but the second and any following aircraft carried the more powerful Sabre V with 2,340 hp, driving a Rotol four-blade propeller. Later aircraft were even to carry the Napier Sabre VII, which was capable of developing 3,400–4,000 hp (2,535–2,983 kW) and pushing the top speed to 485 mph (780 km/h) and more. The third airframe was just a static test structure. However, since the differences between the Tempest and the new aircraft had become almost as big as to its predecessor, the Typhoon, the new type received its own name Cyclone.

 

The first Cyclone Mk. I to fly, on 30 August 1944, was NV950, and it became clear soon that the modifications would improve the Cyclone’s top speed vs. the Tempest by almost 30 mph (50 km/h), but the new components would also require a longer testing period than expected. The annular radiator frequently failed and overheated, and the new, slender wings caused directional stability problems so that the complete tail section had to be re-designed. This troubling phase took more than 6 months, so that eventual service aircraft would only be ready in mid-1945 – too late for any serious impact in the conflict.

 

However, since the Hawker Fury, the land-based variant of the Sea Fury, which had been developed from the Tempest for the Royal Navy in parallel, had been cancelled, the Royal Air Force still ordered 150 Cyclone fighters (F Mk. I), of which one third would also carry cameras and other reconnaissance equipment (as Cyclone FR Mk.II). Due to the end of hostilities in late 1945, this order immediately lost priority. Consequently, the first production Cyclone fighters were delivered in summer 1946 – and in the meantime, jet fighters had rendered the piston-powered fighters obsolete, at least in RAF service. As a consequence, all Cyclones were handed over to friendly Commonwealth nations and their nascent air forces, e. g. India, Thailand or Burma. India received its first Cyclones in late 1947, just when the Kashmir conflict with Pakistan entered a hot phase. The machines became quickly involved in this conflict from early 1948 onwards.

 

Cyclones played an important role in the strikes against hostiles at Pir Badesar and the dominating Pir Kalewa. The taking of Ramgarh fort and Pt. 6944 on the west flank of Bhimbar Gali was to be a classic close support action with Indian forces carrying out a final bayonet charge against the enemy trenches whilst RIAF Cyclones and Tempests strafed and rocketed the trenches at close quarters. On a chance reconnaissance, enemy airfields were located at Gilgit and 40 NMs south, at Chilas. Cyclones flew several strikes against the landing strips in Oct and Nov 48, cratering & damaging both and destroying several hangars, barracks and radio installations. This attack destroyed Pakistani plans to build an offensive air capability in the North. Already, with Tempests and Cyclones prowling the valleys, Pakistani re-supply by Dakotas had been limited to hazardous night flying through the valleys.

 

After the end of hostilities in late 1948 and the ensuing independence, the Cyclone squadrons settled into their peace time stations. However, constant engine troubles (particularly the radiator) continued to claim aircraft and lives and the skill required to land the Cyclone because of its high approach speed continued to cause several write offs. The arrival of the jet-engined Vampire were the first signs of the Cyclone’s demise. As the IAF began a rapid expansion to an all jet force, several Tempest and Cyclone squadrons began converting to Vampires, 7 Squadron being the first in Dec 49. By this time it had already been decided that the piston-engine fighters would be relegated to the fighter lead-in role to train pilots for the new jet fighters. A conversion training flight was set up at Ambala in Sep 49 with Spitfire T Mk IXs, XVIIIs and Tempests to provide 16 hrs/six weeks of supervised Tempest training. This unit eventually moved to Hakimpet two years later and operated till the end of 1952. Some Cyclone FR Mk. IIs remained in front line service until 1954, though.

The kit and its assembly:

Another episode in the series “Things to make and do with Supermarine Attacker wings”. And what started as a simple switch of wings eventually turned into a major kitbashing, since the model evolved from a modded Tempest into something more complex and conclusive.

 

The initial spark was the idea of a Hawker alternative to Supermarine’s Spiteful and Seafang developments – especially with their slender laminar flow wings. Wouldn’t a Hawker alternative make sense?

 

Said and done, I dug out a NOVO Attacker kit and a Matchbox Tempest, and started measuring – and the wing transplantation appeared feasible! I made the cut on the Tempest wing just outside of the oil cooler, and the Attacker wings were then attached to these stubs – after some gaps for the landing gear wells had been cut into the massive lower wing halves. The stunt went more smoothly than expected, the only cosmetic flaw is that the guns went pretty far outboard, but that’s negligible.

 

But the different wings were not enough. I had recently seen in a book a picture of a Tempest (NV 768) with an experimental annular radiator for the Sabre engine (looking like a streamlined Tempest II), and wondered if this arrangement would have been the aerodynamically more efficient solution than the bulbous chin radiator of the Tempest V and VI? I decided to integrate this feature into my build, too, even though not as a copy of the real-world arrangement. The whole nose section, even though based on the OOB Mk. V nose, was scratched and re-sculpted with lots of putty. The radiator intake comes from a FROG He 219, with the front end opened and a fan from a Matchbox Fw 190 placed inside, as well as a styrene tube for the new propeller. The latter was scratched, too, from a Matchbox He 70 spinner and single blades from an Italeri F4U, plus a metal axis. The exhaust stubs were taken OOB, but their attachment slits had to be re-engraved into the new and almost massive nose section.

 

Once the wings and the nose became more concrete, I found that the Tempest’s original rounded tail surfaces would not match with the new, square wings. Therefore I replaced the stabilizers with donations from a Heller F-84G and modified the fin with a new, square tip (from an Intech Fw 190D) and got rid of the fin fillet – both just small modifications, but they change the Tempest’s profile thoroughly.

 

In order to underline the aircraft’s new, sleek lines, I left away any ordnance – but instead I added some camera fairings: one under the rear fuselage or a pair of vertical/oblique cameras, and another camera window portside for a horizontal camera. The openings were drilled, and, after painting, the kit the camera windows were created with Humbrol Clearfix.

  

Painting and markings:

Somehow I thought that this aircraft had to carry Indian markings – and I had a set of standard Chakra Wheels from the late Forties period in my stash. The camouflage is, typical for early IAF machines of British origin, RAF standard, with Dark Green and Ocean Grey from above and Medium Sea Grey from below. I just used the more brownish pst-war RAF Dark Green tone (Humbrol 163), coupled with the rather light Ocean Grey from Modelmaster (2057). The underside became Humbrol 165. All interior surfaces were painted with RAF Interior Green, nothing fancy. The only colorful addition is the saffron-colored spinner, in an attempt to match the fin flash’s tone.

 

As a standard measure, the kit received a black ink wash and some panel post-shading with lighter tones – only subtly, since the machine was not to look too weathered and beaten, just used from its Kashmir involvements.

 

The national markings come from a Printscale Airspeed Oxford sheet, the tactical code with alternating white and black letters, depending on the underground (the sky fuselage band comes from a Matchbox Brewster Buffalo), was puzzled together from single letters from TL Modellbau – both seen on different contemporary RIAF aircraft.

As another, small individual detail I gave the machine a tactical code letter on the fuselage, and the small tiger emblems under the cockpit were home-printed from the official IAF No. 1 Squadron badge.

  

Despite the massive modifications this one is a relatively subtle result, all the changes become only visible at a second glance. A sleek aircraft, and from certain angley the Cyclone looks like an A-1 Skyraider on a diet?

Some background:

The origins of the Henschel Hs 165 date back to early 1937, when the Reichsluftfahrtministerium (RLM, German Ministry of Aviation) issued a specification for a carrier-based torpedo bomber to operate from Germany's first aircraft carrier, the Graf Zeppelin construction of which had started at the end of 1936. The specification was originally issued to two aircraft producers, Fieseler and Arado, and demanded an all-metal biplane with a maximum speed of at least 300 km/h (186 mph), a range of at least 1,000 km and capable both of torpedo and dive-bombing. By the summer of 1938 the Fieseler design proved to be superior to the Arado design, the Ar 195.

Anyway, by the time the Fi 167 prototype was ready for tests and proved its excellent handling, the biplane layout was already outdated and did not promise much development potential. Therefore, the RLM's request was repeated in late 1938 and a monoplane requested. Since the Graf Zeppelin was not expected to be completed before the end of 1940, the RLM did not put much pressure behind the project.

 

Among others, Henschel replied with the Hs 165. It was a compact and conservative low wing monoplane of all-metal construction with a crew of two (pilot and navigator/observer/gunner) under a common, heavily framed and high glasshouse canopy. In order to achieve a high performance, the airframe was originally developed around the new 14 cylinder BMW 139 radial engine with 1,550 hp (1,140 kW). The main landing gear was fully retractable, retracting outwards into wells that were part of the outer, foldable wings. Similar to the Ju87 C, the wings could manually be folded backwards, so that the aircraft became very compact for onboard stowage.

The tail wheel, placed behind a V-shaped arrester hook, could not be retracted, even though a mechanism allowed the control of the tail's ground clearance for the carriage of a torpedo under the fuselage and an optimized angle of attack for starts and landings.

 

Armament consisted of a pair of 20mm MG FF cannons in the wings, a pair of 7.92mm machine guns above the engine, synchronized to fire through the propeller arc, and another single light machine gun for rear defense.

 

Among the special equipment of the Hs 165 for naval operations was a two-seat rubber dinghy with signal ammunition and emergency ammunition. A quick fuel dump mechanism and two inflatable 750 L (200 US gal) bags in each wing and a further two 500 L (130 US gal) bags in the fuselage enabled the aircraft to remain afloat for up to three days in calm seas.

 

When the first two prototypes of the Hs 165 (the V-1 and V-2) were about to be finished, it became clear that the BMW 139 would not materialize, but rather be replaced by an even more powerful engine. The new design was given the name BMW 801 after BMW was given a new block of "109-800" engine numbers by the RLM to use after their merger with Bramo. The first BMW 801A's ran in April 1939, only six months after starting work on the design, with production commencing in 1940.

 

Hs 165 V-1 was re-engined and ready for testing in mid 1940, while the first catapult launch tests on board of the Graf Zeppelin carrier were already carried out with Arado Ar 197s, modified Junkers Ju 87Bs and modified Messerschmitt Bf 109Ds. However, the Graf Zeppelin was still incomplete and not ready for full military service, and the changing strategic situation led to further work on her being suspended. In the wake of this decision, the completion of further carrier-borne aircraft was stopped and the completed examples were taken into Luftwaffe service in several evaluation/test units.

 

The Hs 165 initially fell victim to this decision, and only five airworthy airframes were completed as Hs 165 A-0 pre-production aircraft. Anyway, these were kept in service as test beds and other development duties, and Henschel kept working on detail improvements since the aircraft was also intended to become a land-based replacement for the Ju 87 dive bombers which had become obsolete by 1941, too. This aircraft was planned as the Hs 165 B.

 

However, by the spring of 1942 the usefulness of aircraft carriers in modern naval warfare had been amply demonstrated, and on 13 May 1942, the German Naval Supreme Command ordered work resumed on the German carrier projects. Henschel was happy to have the refined Hs 165 A at hand, and the type was immediately put into production.

 

The resulting Hs 165 A-1 differed in many equipment details from the former pre-production aircraft, and the armament was upgraded, too. The wing-mounted MG FF 20mm cannons were replaced with more effective and lighter MG 151/20 guns, while the pair of MG 17 machine guns above the engine was replaced by a pair of heavy MG 131 machine guns. The observer's single, light MG 15 machine gun was also upgraded to a belt-fed MG 81Z with two barrels, or a single MG 131.

The original BMW 801A engine remained the same, though, and due to the Hs 165 A-1’s higher overall weight the aircraft's performance deteriorated slightly.

 

Production did not last for long though, because further work on the Graf Zeppelin was soon terminated, and this time for good. In the meantime, the RLM had also decided to reduce the variety of aircraft types and rather develop specialized versions of existing aircraft than dedicated types like the Hs 165. As a consequence Hs 165 production was stopped again in June 1943, with several improved versions on the drawing board. These included the A-2 single seater and the C with an alternative liquid-cooled Jumo 213 powerplant.

The land-based Hs 165 B never materialized because, at the time of the type’s introduction into service, the dive bomber concept had turned out to be much too vulnerable in the European theatre of operations. Effectively, the Hs 165 needed cover from more agile fighters and did not stand a chance against enemy fighters.

 

However, until the end of production about 100 Hs 165 aircraft had been delivered to land-based front line units, since no German aircraft carrier ever materialized, and these machines were primarily used in Northern Europe in the coastal defense role and for harassment attacks in the North and Baltic Sea until 1945.

In service, they were gradually replaced by Ju 88 torpedo bombers and the Fw 190 A-5a/U14, which was able to carry a single torpedo, too, but offered a much better performance than the heavy and large Hs 165.

The kit and its assembly:

Another entry for the 2016 "In the Navy" Group Build at whatfimodelers.com, and in this case a complete kitbash for a fictional aircraft. Originally, this idea started as a Hs 126 on floats, which then turned into a low wing aircraft (in the Ju 87 class) and finally evolved into a carrier-capable torpedo bomber. Pretty dramatic evolution, but once the plan was settled, things quickly turned into hardware.

 

Ingredients include:

- Fuselage, cockpit and stabilizers (though mounted differently) from an Italeri Hs 126

- Wings from a Mastercraft (ex ZTM Plastyk) PZL 23 Karas, with the ventral gondala removed

- Landing gear from a Matchbox He 70, wheels from a Mastercraft Su-22;

- Engine/cowling from an Academy Fw 190, plus various donation parts and a putty plug

- Canopy from a Matchbox Brewster Buffalo

- German torpedo from the spares box (IIRC from an Italeri He 111)

 

Even though this is a kitbash, work was rather easy and straightforward, because most of the parts come from OOB donation kits. First, the Hs 126 fuselage was finished without an interior and the Fw 190 nose section transplanted. Inside, a styrene tube was added in order to hold the propeller and let it spin freely. In parallel, the landing gear wells were cut into the wings and the flaps separated/opened. Then the canopy was integrated into the fuselage, using styrene strips and putty.

For the wings, a wide opening had to be cut into the Hs 126’s lower fuselage, and the parts took some putty work to blend together.

Once the wings were in place, the landing gear was mounted as well as the scratched torpedo hardpoint. The cockpit interior followed suit with new seats and two figures, then the Buffalo canopy was modified for the rear machine gun mount and glued into place.

  

Painting and markings:

I wanted a rather "dry", typical German livery, and settled for a simple splinter scheme with a low waterline in the naval colors RLM 72 (a kind of very dark olive drab) and 73 (a bluish, very dark green) with light blue (RLM 65) undersides.

 

In this case I used enamels from the Modelmaster Authentic range, treated with a light black ink wash and with serious panel shading (with Humbrol 66 and a mix of Humbrol 30 + 77, respectively), because some color pictures I got hands on from early German naval aircraft (e. g. He 115 or Ar 196) suggest that the two murky, green tones weathered and bleached easily, and the enhanced contrast between the very similar colors was IMHO helpful, anyway.

 

The interior and the landing gearw as painted in contemporary RLM 02, the torpedo is simple black with a gun metal tip and a brass propeller.

 

The markings had to be puzzled together; I originally wanted the kit to be part of one of the Küstenfliegergruppen, in particular KüFliGr 106. But in mid 1943, these were partly integrated into the Kampffliegergruppen, and offensive parts of KüFliGr 106 were added to KG 6. It took some time to figure out where KG 6 was operating in the time frame I wanted to place the Hs 165, and eventually found 8./KG 6 from the third group that was based in Belgium at that time and flew Ju 88 torpedo bombers - so I added the Hs 165 to that squadron.

 

As a side effect, the aircraft would not carry any of the fuselage bands or other bright ID markings - the only color highlights are the red wing tip and the individual code "K" letter, and I used a grey decal for the 8th squadron's code letter "S" for better contrast with the dark green livery. Another "highlight" is a KG 6 emblem behind the engine, which I found on a Peddinghaus Decals sheet in the stash. Anyway, this minimal and very conservative livery does not look bad at all, though?

  

A complex kitbashing,done in about a week, and despite some trouble and major body work the result looks IMHO very good - especially the flight scenes, with the retracted (retouched...) landing gear show the sleek lines of the Hs 126, the fictional Hs 165 looks pretty fast and purposeful. And with a different engine, this could also carry some Hinomaru - the thing reminds me a lot of Japanese torpedo bombers (e. g. the B5N?) and carrier-borne reconnaissance aircraft?

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.

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 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.

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

  

Some background:

The Fouga CM.170 Magister was a 1950s French two-seat jet trainer aircraft, developed and manufactured by aircraft company Fouga. Due to industrial mergers, the aircraft has been variously known as the Fouga CM.170 Magister, Potez (Fouga) CM.170 Magister, Sud Aviation (Fouga) CM.170 Magister and Aérospatiale (Fouga) CM.170 Magister, depending on where and when they were built.

 

In 1948, development commenced at Fouga on a new primary trainer aircraft design that harnessed newly developed jet propulsion technology. The initial design was evaluated by the French Air Force and, in response to its determination that the aircraft lacked sufficient power for its requirements, was enlarged and adopted a pair of Turbomeca Marboré turbojet engines. First flying on 23 July 1952, the first production order for the type was received on 13 January 1954. Export orders for the Magister were received, which included arrangements to produce the type under license in Germany, Finland, and Israel. In addition, the related CM.175 Zéphyr was a carrier-capable version developed and produced for the French Navy.

 

While primarily operated as a trainer aircraft, the Magister was also frequently used in combat as a close air support platform by various operators. In the latter capacity, it saw action during the Six-Day War, the Salvadoran Civil War, the Western Sahara War, and the Congo Crisis. In French service, the Magister was eventually replaced by the Dassault/Dornier Alpha Jet, and a navalized variant (the CM.175 “Zéphyr”) was procured and operated from 1959 onwards by the Aéronavale.

 

Beyond that, the basic 1950 design was considered for several upgrades or specialized variants – including a high altitude trainer or a dedicated single-seat attack aircraft. In 1957 even a supersonic variant was proposed: the CM.174, which featured swept wings and tail surfaces. However, this initial aircraft never made it to the hardware stage because wind tunnel tests revealed serious compressibility issues at speeds beyond Mach 0.65, and that the potential gain in performance through the new wings could not be tapped.

 

However, this was not the end of the Magister’s potential; in 1957 Fouga presented a model of the CM 194 at the Paris Air Show – a much updated aircraft, powered by a pair of stronger Gabizo engines and capable of supersonic speed, even though only in a dive. French officials and some potential foreign customers (e.g. Israel) were interested enough to convince Fouga to build a demonstrator, even though as a private venture. The first prototype left the Toulouse factory in May 1958, the first type to bear the Potez designation after Fouga had just been purchased by the firm.

 

The CM.194 differed in some details from the model that had been presented – primarily in order to save development time and costs. The basic fuselage structure from the original CM.170 was retained, but the CM.194 introduced completely new wings and tail surfaces, a modified landing gear, a pointed nose and an elongated spine fairing that helped improve the aircraft’s aerodynamics for the flight in the Mach 1 region. Power came from a pair of Turbomeca Gabizo, but in order to improve the aircraft’s performance and make it suitable for the advanced jet fighter trainer role, the relatively small engines even received afterburners (an arrangement originally developed for the stillborn Breguet Br 1001 “Taon” tactical fighter). With this extra power, the CM.194 was now able to break the sound barrier in level flight and attain a top speed of Mach 1.18, and the type could carry a considerably higher payload than the original CM.170.

 

Flight tests started in late 1958 and revealed good handling characteristics, even though longitudinal stability near Mach 1 was considered as unsatisfactory, and the air intakes had to be modified because of airflow problems and engine surges at supersonic. It took until mid 1959 until an enlarged butterfly tail with crescent shape, together with an extended spine fairing, eventually solved the stability problem. The engine surge problem was solved through the introduction of movable shock cones in the air intakes, similar to the “souris” (mice) arrangement on Dassault’s Mirage III and IV.

Two more prototypes had been built at that time, being marketed as the “Magister Supersonique”, or “Magister SS” for short, and a demonstration tour around the globe in many countries of Magister operators was conducted from October 1959 until April 1960.

However, the CM.194 did not meet much interest. Even though many air forces, also smaller ones, were about to enter the supersonic age and were looking for advanced trainers, the market had been conquered by politically endorsed alternatives in the meantime, namely the Northrop T-38/F-5B and the MiG-21U, and these contenders were much more capable than the relatively light CM.194.

 

Nevertheless, the French air force procured 42 CM.194 trainers, the first operational aircraft being delivered in early 1963, and some other countries ordered the type, too, including Austria, Belgium, Lebanon and Morocco. Israel even secured license production rights of the aircraft as the IAI T-270 “Drowr” (Swallow). A total of 132 aircraft were built until 1974, and the last CM.194 was retired by El Salvador in 1995.

The kit and its assembly:

This little what-if model is actually based on a real world design – the potentially supersonic Fouga CM 194 was actually presented in model form in 1957, but it never made it to the hardware stage. I found this aircraft in a book about French aircraft projects and had this build on my long project list for a while. When a fellow modeler at whatifmodelers.com (Weaver) presented a very nice swept wing Magister (an Airfix CM 170 with G.91 wings and F-86 stabilizers), I took it as a motivation and prepared a build of my own.

 

My build differs from Weaver’s approach, though, even though the G.91 wings are a very natural option for the slender Magister. In my case, the fuselage was taken from a Heller CM 170, including the cockpit except for the bucket seats, which were replaced by more appropriate ejection seats. I also used G.91 wings for my build, but these came from the Revell kit. And even though I had a pair of F-86 stabilizers at hand (which are a very good addition to the G.91 wings), I did not use them because I found them to be too small for a butterfly tail on a Magister. After all, two aerodynamic surfaces have to do the job of three on a conservative tail, so that the sum of the surfaces’ areas have to be similar. The best alternative I could find in my donor bank was a pair of stabilizers from a Matchbox Harrier; while their shape looks a little odd, their sweep angle is fine and their size works well.

 

Beyond these obvious changes, some other modifications ensued. The nose tip was changed into a pointed shape, and the area behind the cockpit (the canopy is OOB, just cut into pieces for open display) was raised through the integration of a drop tank half and some serious PSR – inspired by the look of Fouga’s first attempt to make the Magister supersonic, the CM 174. Since the G.91 wings came with different landing gear wells, I decided to change the landing gear itself and use the G.91’s main struts and covers, while the Magister’s OOB main wheels were kept. The front leg was changed in so far that I attached it to the rear end of its well, and I used a slightly bigger wheel (IIRC from an 1:144 B-1B). All in all the aircraft’s stance was raised, it looks much more mature now. And in order to keep its lines clean I did not add any external weapons or even pylons. After all, it’s a flight trainer.

 

Another modification concerns the engines – for a supersonic aircraft I added small shock cones in the air intakes (scratched from styrene profile) and I changed the exhaust section, so that bigger/stronger engines would be plausible. I implanted a pair of modified lift engines from a Kangnam Yak-38 kit – I thought they’d be small enough, but on the compact Magister they still appear big! Luckily I found the Br 1001 “Taon” and its afterburner Gabizo engines in literature, so that the arrangement on the model can at least be explained through historical facts. ;-)

  

Painting and markings:

I was tempted to finish the model in Israeli markings, like Weaver’s, but then rather opted for a different route: I wanted to present the CM 194 in very normal operational colors, nothing exotic. After considering several options (Morocco, El Salvador, France) I eventually settled upon Belgium, and I went for the tactical three-tone scheme that was carried by the F-104 or Mirage V fighter bombers.

 

The pattern was adapted from an Alpha Jet export scheme and the colors were approximated from photo benchmarks. Many sources claim that the colors are the standard US SEA scheme, consisting of FS 34079, 34102 and 30219. However, the Dark Green is simply wrong (it’s a tone called FS 34064, and it’s a very dark olive drab), and the other colors come out much brighter than on typical US aircraft.

 

Consequently, FS 34102 was replaced by RAL 6003 (later even post-shaded with Humbrol 80, Grass Green!), while the tan tone is a mix of FS 30219 with Humbrol 94 (Desert Yellow). FS 34064 was created with a 1:1 mix of Humbrol 108 and 91 (later post-shaded with 75). The undersides were painted in FS 36495.

 

The cockpit interior became dark grey (Revell 77), while the landing struts and the wells were painted in aluminum; the covers’ inside received a finish in Chromate Yellow (Humbrol 81).

 

The dayglow markings on the tips of wings and the butterfly tail were created with decals sheet material, on top of which some paint (Humbrol 209) was added for a slight shading effect.

Generic decals in silver were also used to create the wing leading edges. National markings and warning stencils come from the scrap box.

Finally, the kit received a coat of matt acrylic varnish (Italeri).

  

Well, basically a simple conversion stunt, but it’s actually a complete kitbashing with – in my case – some considerable PSR work. However, the result is a very plausible, if not pretty, aircraft. From certain angles, the swept-wing Magister reminds me of the Alpha Jet (esp. the nose section, probably due to the pointed nose?), and the whole thing appears somehow bigger as it actually is. And I like the paint scheme: even though it’s camouflage, the dayglow markings and the bright insignia and stencils create a lively look.

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.

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.

Some background:

RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym.

 

They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (Sekcja Lotnicza Koła Mechaników Studentów), where they manufactured their first designs. From 1926 they designed several aircraft alone, in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Polish Air Force’s Okęcie aerodrome, today's Warsaw International Airport.

 

At first, the RWD team designed and built light sportsplanes. Early designs were built in small series and used in Polish sports aviation, including their debut at the Challenge 1930 international contest. Their next designs performed particularly well in competitions - the RWD-6 won the Challenge 1932 and RWD-9s won the Challenge 1934 international contest. The sportsplane RWD-5 was the lightest plane to fly across the Atlantic in 1933. Three types saw mass production: the RWD-8, which became the Polish Air Force basic trainer, the RWD-13 touring plane and the RWD-14 Czapla reconnaissance plane. Other important designs were the RWD-10 aerobatic plane (1933), RWD-17 aerobatic-trainer plane (1937) and RWD-21 light sport plane (1939). Their most ambitious design that entered the hardware stage and eventually took to flight was the RWD-24, a fighter aircraft. However, World War II prevented further development and serial production of later RWD designs, and also put an end to the RWD construction bureau and its workshops.

 

The RWD-24 had been designed in response to a requirement for a fighter issued by the Polish Air Force in 1934. RWD responded and built a prototype of mixed materials, heavily influenced by French designs and resources, since Poland had procured several fighter, bomber and reconnaissance aircraft from France during the mid-twenties.

 

RWD’s design team quickly projected that only a monoplane design would be capable of delivering the desired level of performance sought; other modern features were to include a fully enclosed cockpit, a variable-pitch propeller, and landing flaps. The resulting RWD-24 was a high-wing monoplane of mixed construction, with fabric-covered wooden tail and rudders. The wings were directly attached to the upper fuselage and braced. They consisted of a two-spar duralumin structure, complete with rivetted ribs to both the spars and skin. The exterior of the wing was covered by finely corrugated duralumin sheet, while the slotted ailerons had a fabric covering.

 

Power came from a water-cooled Hispano-Suiza Y V12 engine – a novelty among Polish fighter designs, which traditionally relied upon radial engines, e.g. the Bristol Mercury and Jupiter, imported as license builds from Czechoslovakia (Skoda). The Hispano-Suiza engine meant a considerable step forward, though, since it increased the output by almost +50%, with appreciable improvements of overall performance that promised to put the RWD-24 on eye level with other contemporary foreign monoplane fighters.

 

In order to improve performance further, much effort was put into aerodynamic effectiveness, despite a rather conservative structure with bracing struts for the wings and stabilizers. For instance, the ventral radiator could be retracted manually, adapting the frontal area to the engine’s cooling needs. The RWD-24’s landing gear was fixed but covered with aerodynamic fairings and spats.

 

Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.404 cannon with 60 rounds from a drum magazine, mounted as a “moteur canon” between the cylinder banks and firing through the propeller hub, plus two pairs of 7.92 mm (0.312 in) KM Wz 33 machine guns with 450 RPG in the wings outside of the propeller disc. The prototypes only carried the cannon and a single pair of machine guns, though.

 

First flown by RWD-founder Jerzy Drzewiecki himself, the first prototype demonstrated the type's favorable flying characteristics from the onset – even though the poor field of view for the pilot ahead and downwards during landing and taxiing was criticized. Another critical point was the retractable radiator; while it allowed a remarkable boost in top speed for short periods, the manual temperature management – esp. during combat situations – turned out to be impractical and an automated solution was requested. The firepower of the 20mm cannon received praise, too, despite its limited ammunition capacity. After 80 hours of test flights, in January 1936, the prototype was delivered with all military equipment fitted to the Polish Air Force at Okęcie aerodrome to participate in service trials, while a second prototype was built in parallel and joined the program in May. It differed from the first RWD-24 through a different tail section, which was covered with a bonded metal/wood material (Plymax) skin fixed to duralumin tubing.

 

Despite its good handling qualities and impressive performance (the contemporary Polish standard fighter, the PZL P.11, had a top speed of 390 km/h (240 mph, 210 kn), while the RWD-24 surpassed 440 km/h (273 mph, 240 kn) at ideal altitude), both the shape and basic configuration of the RWD-24 were hotly contended, particularly between 'traditional' advocates of biplane aircraft and supporters of 'modern' monoplane with retractable landing gear. The RWD-24 would not satisfy either party, and the high wing layout offered no real development potential, together with the field of view issues. Only a complete redesign of the RWD-24 into a low-wing configuration with a retractable landing gear would have been a viable solution. RWD engineers deemed this task to be feasible, but the Polish Air Force did not want to wait any longer for a new fighter aircraft. In consequence, the RWD-24’s development was officially stopped in early 1938, after only two airframes had been built. In the meantime, RWD had also started work on a dedicated low-wing fighter powered by a 800 hp (597 kW) Gnome-Rhône Mars radial engine, the RWD-25, but until then only a mock-up of this alternative type had been built.

 

However, the two RWD-24 prototypes remained based at Okęcie and were further tested by both the company and by the Polish Air Force. During these test in 1938, the RWD-24s were, among others, evaluated against a Hawker Hurricane Mk.I and a Dewoitine D.520 that had been delivered to Poland for trials (and eventual sales). In the meantime, driven by rising political tensions and threatened by neighboring Germany, the Polish Air Force had started to follow the idea of importing fully developed monoplane fighters in order to quickly boost the country’s air power and deterrent potential. This eventually led to the procurement of Hawker Hurricanes from Great Britain in 1939. But this decision came too late: the fighters were not delivered before 1 September 1939, when Germany invaded Poland, and the Polish Hurricanes on order were alternatively sent to Turkey instead.

 

Upon the German invasion the RWD-24 prototypes were, together with most other active Polish combat aircraft, dispersed to secondary airfields and allocated to the so-called Pursuit Brigade, deployed in the Warsaw area, where both served until they became unserviceable after a week, due to their exotic nature. Their fate remains unclear, though, since both machines disappeared. But most likely they were both destroyed within two weeks, like 70% of the Polish Air Force’s aircraft.

The kit and its assembly:

This was a rather spontaneous submission for the “Prototypes” group build at whatifmodelers.com in July 2020, originally spawned by the idea of retrograding a Morane Saulnier MS.406 into a biplane with a fixed landing gear, a kind of French Gloster Gladiator. However, this changed when I found a surplus Mistercraft PZL P.7 kit in the stash, which had been part of a combo deal some time ago. Why not use it for a kitbashing and create a late interwar period Polish fighter prototype from the MS.406…?

 

The MS.406 fuselage comes from the simple Hobby Boss kit, even though some serious bodywork had to be done in order to make the low wing attachment points and the respective large wing root fairings disappear – on the simple Hobby Boss kit, wings and lower fuselage are one integral part, so that some major cutting and PSR were necessary to create a new, “clean” lower fuselage. For the new wings a piece of the cowling in front of the windscreen had to be cut out, the result looks very natural, though, the P.7 wing literally fell into place. The P.7 wings were taken, together with their respective support struts, wholesale from the Mistercraft kit, I just added flaps and lowered them, and I added fairings under the wings for the machine guns – OOB the kit comes with shallow holes that look a bit strange?

 

The empennage was taken over from the MS.406, but the stabilizers were replaced with the P.7’s, because they were bigger and their shape matches the fin so well. The fixed landing gear is a donor from an ICM Heinkel He 51 floatplane (surplus parts), it was just shortened by about 2mm in order to avoid an exaggerated nose-up stance due to the high propeller position.

 

The cockpit was taken OOB, just a pilot figure was added to hide the Hobby Boss kit’s rather basic interior.

  

Painting and markings:

Prototype liveries tend to be dry affairs, and therefore my RWD-24 received a standard pre-WWII livery for Polish aircraft in a uniform brownish-green khaki (”Light Polish Khaki”) over light blue wing undersides. For the very unique khaki tone I used Modelmaster 1711 (FS 34087, a rather yellowish interpretation of this tone), while the wings’ undersides were painted with Humbrol 65 (Aircraft Blue). The khaki tone was - on Polish high wing aircraft of the time - typically carried on the whole fuselage, including the undersides, so I adopted the tone for the complete landing gear and the wing struts, too. For a little more variety, I gave the engine a cowling in a bare metal finish (Humbrol Polished Aluminum Metallizer) and the airframe parts that are covered with fabric were apinted with Humbrol 155 - FS 34087, too, but a morre greenish and darker interpretation of this tone.

 

The kit received a black ink washing and some post-shading through dry-brushing of single panels with lighter tones. The cockpit interior was painted in a medium grey, the propeller blades became Revell 99 (Aluminum) with red tips, a black spinner and partly blackened back sides (in order to avoid light reflections that could blind the pilot).

 

Most markings come from a Polish aircraft aftermarket sheet. The red lightning cheatline on the fuselage and on the wings were borrowed from Indonesian MiG-21Fs (from two Begemot sheets). The contrast to the khaki is not strong, but I thought that some decoration would suit a prototype fighter well. The tactical codes consist of single white and black letters (both TL Modellbau stuff).

 

After some exhaust and gun soot stains the model was finally sealed with matt acrylic varnish, just the metallic cowling and the spinner received a light shine.

  

While the outcome looks rather unsuspicious, this kitbashing was a lot of work – esp. the landing gear and the cosmetic surgery to remove the MS.406’s lower wings was more demanding than I had thought at first. But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.

 

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!

  

Some background:

The Supermarine Jetfire was a stopgap solution in order to introduce a jet-powered interceptor agains German V-1 missiles that threatened the London region from June 1944 on. At that time, the only aircraft with the low-altitude speed to be effective against it was the Hawker Tempest, but fewer than 30 Tempests were available. They were assigned to No. 150 Wing RAF, and early attempts to intercept and destroy V-1s often failed.

 

One alternative was the jet-powered Gloster Meteor, which still was development - and in order to get the new engine into service (also as a response to Gloster's engagement for E.1/44 with the single-engine "Ace" fighter) Supermarine responded with the idea to replace the nose-mounted piston engine with a single Whittle W.2 engine: The "Jetfire" was born.

 

The conversion was rather simple: the Jetfire was actually a Griffon-powered Spitfire XIV with as few changes to the original airframe in order to accept the W.2. The aircraft's forward fuselage was widened to accommodate the bulbous engine with a simple nose intake. The deeper forward part of the fuselage with its round diameter gave the aircraft a pronounced "pod-and-boom" configuration.

 

Internally, the front wing spar had to be bent into an inverted U-shape to clear the engine and its jet pipe.

The W.2 was mounted slightly angled downwards, and the jet pipe was bifurcated so that it ran along the fuselage flanks above the wings, with an exhaust just behind the wings’ trailing edges. To protect the fuselage, steel heatshield were added to the flanks. Furthermore, the former radiator fairings for the Griffon and the respective plumbing were removed and faired over, saving weight and internal space – and weight was reduced as much as possible to achieve a decent performance with the rather experimental centrifugal jet engine. The conventional Spitfire tailsitter landing gear remained unmodified, just additional covers for the main wheels were added for improved aerodynamics at high speed.

 

The first prototype was already finished in October 1944, and taxiing trials started immediately. The heatshields proved to be too short and the heat from the engine exhaust melted the duralumin skin of the rear fuselage. Additionally, the tailwheel received a longer strut for a cleaner airflow under the stabilizer on the ground – the original, shorter strut created an air cushion under the stabilizer that lifted the whole tail upwards when the throttle was opened, resulting in poor handling at low taxiing speeds.

 

Modifications to rectify the problems took until late December, and by this time a second prototype had been completed. After a few taxiing tests, it was transferred to the Royal Aircraft Establishment (RAE) for full-scale wind tunnel testing that lasted until February 1945.

 

On the 26th of that month, the RAF issued requirements that the aircraft should have a maximum speed of 770 km/h (480 mph) at sea level and a speed of 850 km/h (530 mph) at an altitude of 5,000 meters (16,400 ft). It should be able to climb to that altitude in 4 1/2 minutes or less and it should have a range of 500 kilometers (310 mi) at 90% of maximum speed.

 

The Jetfire failed to meet these targets, but it was still fast enough to intercept the V-1 and was quickly available. The average speed of V-1s was 550 km/h (340 mph) and their average altitude was 1,000 m (3,300 ft) to 1,200 m (3,900 ft). Fighter aircraft required excellent low altitude performance to intercept them and enough firepower to ensure that they were destroyed in the air rather than crashing to earth and detonating. Most aircraft were too slow to catch a V-1 unless they had a height advantage, allowing them to gain speed by diving on their target.

 

Originally a total of 200 Jetfire Mk.Is were ordered, and on the drawing board an improved variant with a bubble canopy, a slightly larger tail fin, stabilizers with a 10° dihedral in order to get them better out of the jet efflux’s path and an armament of four 20 mm cannon (the Mk.II) was already taking shape. But this initial and any follow-on orders were quickly cancelled or changed to the more advanced and promising twin-engined Gloster Meteor that finally became operational.

 

Consequently, the total production run of the Jetfire Mk.I just reached 26 aircraft: 18 were delivered to RAF 616 Squadron, the rest were used by the Tactical Flight at Farnborough that had been established in 1944 in order to prepare active squadrons for the radically new jet fighters. In late March 1945, the Jetfires became operational, upon which both tactical applications and limitations were extensively explored.

 

Despite many shortcomings (sluggish acceleration, poor climb and agility except for a very good roll rate), the still rather experimental and primitive Jetfire was able to fulfill its intended V-1 interception role, and two V-1 interceptions were achieved during the following weeks. In the front line units they were quickly replaced by more effective types like the Gloster Meteor, the Hawker Tempest or the Republic P-47 Thunderbolt. Anyway, the Jetfire was still helpful to path the RAF’s way for operational jet fighters and helped discover new high speed problems, including compressibility buffeting at higher speeds, causing increased drag, and it showed clearly the limits of traditional fighter aircraft designs.

The kit and its assembly:

The first entry for the "Old Kit" group build at whatifmodelers.com in late 2016 - anything goes, the kit's mould just has to date back to 1985 and further. For this one I settled on the FROG Spitfire Mk. XIV, which, AFAIK, dates back to 1969, and an engine donor from a KP Yak-23, which is supposed to have hit the markets behind the Iron Curtain in 1981.

 

Originally, the background story pretty much sums up the idea behind this kitbash: How could the - already fast - Spitfire be further augmented with one of the new jet engines around 1944, when V1 attacks started against the British main land and the Meteor was still in development? A simple engine swap with as much airframe of the piston-engine ancestor would be the answer. Similar ideas had been undertaken in Germany, with re-engined versions of the Bf 109 and the Fw 190, and after WWII, when German jet technology had become available to the Soviet Union, the Yak-15/17/23 family followed a similar pattern.

 

The Yak-23 came as a natural donation aircraft for the Derwent nose. After careful measures and strategic cuts the Spitfire lost its Griffon engine (already earmarked for another kitbash...) and the Yak-23 its nose and exhaust pipe: the original plan had been to use a central, ventral exhaust pipe under the cockpit, even though this would create issues with the tail wheel (just as on the Yak-15 - it received in service an all-metal tail wheel! Imagine the sparks on the runway...).

 

Anyway, while dry-fitting the parts it turned out that pretty little of the Yak-23 exhaust section could be mounted with clean lines: I'd either have had to create a semi-recessed exhaust with lots of body work (and pretty implausible), or switch to a totally different solution.

 

That came with a bifurcated exhaust pipe, running along the wing roots and ending at the wings' trailing edge. While this sounds weird, too, the Hawker SeaHawk actually had such an arrangement - on a service aircraft!

As a side effect, the fairings for the jet pipes now offered a good basis for the necessary intersection between the round and bulky Derwent nose fairing and the narrow, oval Spitfire fuselage.

 

The new jet pipes were created with styrene tubes and lots of putty, and the result does not look bad at all. Actually, with the deleted radiators and the Griffon carburetor intake gone, the aircraft has a very sleek profile, even though the top view reveals the innate "pod and boom" layout of the nose-mounted centrifugal jet engine.

 

The latter received a new intake interior with some fine mesh and a central bullet fairing (the Yak-23's vertical splitter would not make any sense, since there'd be no nose wheel anymore). The landing gear was taken more or less OOB, I just added some struts and extra wheel covers. The tail wheel comes from an Airfix Hawker Hurricane and changed into a fully retractable arrangement. The cockpit was taken OOB, too, just a tank dummy was added behind the pilot's seat and the canopy sliced into three pieces for an optional open display.

 

The "E wing" armament was taken over from the Spitfire Mk. XIV, I just added the elegant drop/slipper tanks from the Yak-23 kit. This breaks up the clean lines of the "Jetfire", but I think that the thirsty Derwent might have needed some extra fuel for a decent approach range and some loiter time while intercepting incoming V-1s?

 

The V-1 from the FROG kit was built for the flight scenes, too. It’s a very simple model consisting only of four parts with rather mediocre fir, esp. the pulse engine halves, but a fairly good representation. Maybe the propeller for the fuse timer is missing, but that can be scratched easily.

Only personal additions are a grate in the air intake, and a hidden adapter for a display, for the pics. Maybe this flying bomb ends up later as ordnance under a German bomber build?

Very conservative, late war RAF Dark Green/Ocean Grey/Medium Sea Grey with typical ID markings and codes. 616 Squadron was chosen because it was one of the units that introduced the Meteor for V-1 interception.

 

Paints are basically enamels from the ModelMaster Authentic range. The Sky fuselage band was improvised with a decal from a vintage Matchbox Brewster Buffalo (matching the the Sky code letters from Xtradecal pretty well), while the codes and serial numbers themselves were created from single letter digits (the "/G" addition to the serial number signaled that the aircraft was to be guarded at any time while on the ground).

 

The cockpit interior was painted in very dark grey while the landing gear became aluminum. As a highlight, the air intake edge was painted with silver, more for a dramatic effect than for realism.

The yellow wing leading edge markings were created with generic decal sheet material. The only special markings on the aircraft are the white stripes on tail and wings, which I also used to underlay the serial code.

 

Only little panel-shading and weathering was done, some panel lines were manually created with a fine pencil since a lot of surface details on the fuselage were lost during the extensive PSR process around the wing/jet pipes area.

 

Finally, the kit was sealed with matt acrylic varnish.

 

The V-1 has painted with no special paradigm in mind, with RLM81 upper surfaces and RLM 76 undersides, with a very wavy waterline and some grey patches on the wings. The engine was painted with aluminum first and then a thin coat of red primer added.

  

The resulting aircraft of this kitbash looks better than expected, even though the change of the exhaust arrangement came unexpected – even though I think the Jetfire became more appealing through the side pipes, despite the overall tadpole proportions.

As a side note, the story is not over yet, because there’s an engine-less Yak-23 left over, and I wonder what it might look like with a piston engine grafted to the empty nose?

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:

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:

At the end of WW2, Sweden was in search of a new fighter offering better performance than the J21 could offer. The latter was an indigenous fighter/attack aircraft from SAAB that first took to the air in 1943 and dated back to a requirement from 1941. The J21 was designed as an unusual twin boom pusher configuration, where the propeller was mounted in the rear of the fuselage, pushing the aircraft forward. The advantages of a pusher design were that the view forward was unobstructed and armament could be concentrated in the nose, while the heavy engine was placed close to the center of gravity for better handling and agility. A major drawback was the difficulty in escaping from the aircraft in an emergency, though, as the pilot could get drawn into the propeller blades. SAAB deliberated between systems that would eject the pilot, or jettison the propeller or even the whole engine, via a system of explosive bolts, and eventually installed an early, explosives-powered ejector seat developed by Bofors for this purpose.

However, the SAAB 21 had its share of trouble (overheating an unreliable DB 605 engine), and in 1944 a new requirement for a more powerful and conventional fighter was issued. Selecting the Rolls Royce Griffon as the powerplant, SAAB initially looked into adapting the engine to the J21. However, this proved impractical, so SAAB started work on a clean-sheet design.

 

The L27, as it was known in the project stage, ended up closely resembling the latest designs to come from Britain like the Supermarine Spitfire or the Martin Baker MB 5, as well as the North American P-51 Mustang. The Griffon engine, chosen for initial development and flight tests, drove a contra-rotating propeller and sat in the nose. Top speed with the Griffon was expected to be around 700 km/h (435 mph). Later production aircraft were to be powered by a domestically developed, new H-24 cylinder motor similar to the British Napier Sabre engine and delivering output in significant excess of 2.200 hp (1.640 kW). With this machine, the aircraft was expected to reach a top speed of 740 km/h (460 mph) or even more.

 

The wings were similar to those used on the Fairey Firefly, complete with Fairey’s characteristic Youngman flaps, but with small wing root extensions and a thicker profile than the late Spitfires’ wings, and with more rounded wing tips. Similar to the P-51, the L27’s landing gear with a wide track retracted inwards into the wings, and the tail wheel could be fully retracted, too.

Armament, consisting of four 20mm Hispano cannons, was to be concentrated in the wings just outside of the propeller arc, and unlike the Spitfire’s arrangement with underwing coolers, the L27’s single radiator was placed in a ventral tunnel position, very similar to the arrangement on the P-51.

 

A total of three prototypes were ordered, and the aircraft was now formally designated J27A; two were to be powered by Rolls-Royce Griffon 83 engines, and one as a test structure and earmarked for the development of the 24 cylinder engine and its integration into the projected J27B.

The first flight of a J27A took place in March 1945, and the promising results kept the project evolving until late 1946, when the aircraft was cleared for service and production in January 1947. 70 aircraft with Griffon engines were ordered.

 

Anyway, in early 1945, SAAB had also launched a project to determine how to provide the J21A with a jet engine to get the experience of jet engines and flying at high speeds. The goal was to catch up with the development of jet aircraft, which were moving ahead fast in England, where, among others, de Havilland already had the de Havilland Vampire in production. The resulting J21R, SAAB's first jet, made its first flight on 10 March 1947 and it marked the death knell for any piston-engine fighter development and use in Sweden. Consequentially the 24 cylinder engine never made it from the drawing board, and after the initial production run of the Griffon-powered J27A was completed until early 1949, further production was stopped and the whole J27 program terminated. Serial production J27As differed only slightly from the prototypes. The most obvious change was a taller vertical stabilizer and a small fin fillet, less obvious was a modified landing gear cover arrangement, because the original design with a single, large cover of the main wheels tended to bulge outward at high speed. A split design mended this problem.

 

While the J27A’s projected top speed of 700km/h was impressive for a piston-engine fighter and frequently confirmed in service, it was inadequate in the oncoming jet age. In the end, SAAB opted to pursuit jet fighter endeavors that soon led to the very modern and innovative SAAB J29 that soon became Sweden’s standard jet fighter.

In frontline service the J27 was, even though it was popular among its pilots and maintenance crews, almost immediately replaced by jets, at first with the J28B Vampire (from 1951 on), which were in turn quickly replaced in 1952 with the indigenous J29 Tunnan.

The last J27A was, after serving with fighter units primarily in southern Sweden, already retired from frontline duties in 1955. Some aircraft, though, were kept in service as target tugs, liaison aircraft for the air staff and for dissimilar air combat training. The last machine was finally decommissioned in summer 1961.

The kit and its assembly:

This is a “real” what-if model, or at least the attempt to build a phantom aircraft from single parts! The SAAB 27 is a bit of a mystery, because valid information is sparse, especially concerning details about its shape. You find some drawings or profiles, but IMHO these are based on guesswork and rather vague. The J27 is frequently described as a “Swedish Spitfire with a P-51 radiator” or a “Swedish Super-Spitfire”, but that leaves much to be desired, because the similarity is only superficial. Hence, this model here is rather a free interpretation of what a service J27 could have looked like.

 

For long time I fought with two building options: either convert a Fairey Firefly (Airfix’ Mk. 5 would have been my bet), or use a Spitfire Mk. 22. After long considerations I settled for the latter one, because I feared that the Firefly would result in a rather massive aircraft, and the Airfix kit itself is vintage and worth a building fight on its own.

 

So I used an Airfix Spitfire Mk. 22, but from this (very nice!) kit just a few things were taken, because I wanted a more individual look. Only the fuselage, cockpit interior and landing gear survived, and I even inserted a 2.5mm wide “wedge plug” around the cockpit and wedge-shaped inserts at the fuselage halves’ seams in order to add some beef to the sleek (if not spindly) Spitfire. I think it’s hard to notice, but the overall proportions look good. At the tail and the front end, the original fuselage width was kept, though.

 

Reason behind this was the P-51 radiator’s width (leftover from a Matchbox kit) that was considerably wider than the Spitfire fuselage. Furthermore, the thicker/more massive wings from a P-47 (from an early MPM kit) also called for a more massive body.

For the new wings, some adaptations to the Spitfire wing roots had to be made, though, e.g. a bulged mid-wing section under the fuselage. The Thunderbolt parts also had the benefit of wells for a landing gear that retracts inwards. I also used P-47 landing gear parts, even though the struts were shortened at their bases by 3mm and the covers accordingly. For the sake of a different look (the Spitfire wheels are very characteristic) I used different main wheels from a Revell G.91R. The landing gear cover arrangement differs from J27 sketches (as far as I can tell, it must have been similar to the P-51's), but I stuck with the P-47 parts because they match well with the rest of the aircraft.

 

The contraprop belongs to a late mark Seafire, left over from a Special Hobby kit. The propeller was in so far modified that I added a metal axis and a styrene tube adapter for the fuselage, so that both propeller parts can (theoretically) spin. OOB, the Special Hobby solution is simply to be glued onto the nose, fixed, despite being constructed in two separate parts?

 

Furthermore, the carburetor intake was changed: the Spitfire’s scoop at the wings’ leading edge was replace by a Firefly-style lip intake right behind the propeller.

 

The whole tail section was reconditioned, too. Descriptions of the J27’s tail are corny, but “more square than a Spitfire’s”. Instead of simple cosmetic surgery I thoroughly replaced the OOB fin with a Supermarine Attacker’s (Novo kit) with some mods to the outline, which fits well in size and is …more square!

 

The new tail is a bit taller and has a fin fillet, making it look very P-51-ish, but that’s O.K. for me. At least it’s different from the round Spitfire shape.

I also exchanged the stabilizers, the round Spitfire parts gave way to differently shaped pieces from a Hobby Boss La-7. Their shape is similar to a P-47’s, but they are smaller and match J27 illustrations well.

 

The canopy was also changed. Through the widened fuselage around the cockpit the tight OOB Spitfire hood would hardly match, anyway. The bubble layout remained, and I adapted a bigger Matchbox P-51 canopy to the new fuselage contours, and moved forward as far as possible.

  

Painting and markings:

The Swedish Air Force as operator was settled, as well as early post-WWII markings. But I did not want the standard, uniform olive green/blue grey livery, so I painted the upper surfaces with camouflage scheme made from two green tones: a medium green tone (Humbrol 102, Army Green, ~FS 34096) and a bluish, dark green (Humbrol 91, RLM 70 equivalent), applied in bands – somewhat inspired by a scheme carried by some SAAB 32 Lansen in the early 60ies.

 

The underside was kept in the typical Swedish blue-grey, for which I used Humbrol 87. The waterline was placed very low so that the upper camouflage was also taken to the radiator flanks under the fuselage and wings.

 

The cockpit was painted in very dark grey (Humbrol 32), while the landing gear and the wells were kept in Aluminum (Humbrol 56).

 

As a 2nd squadron machine, the code letter became blue, as well as the two-part spinner, latter’s paint was mixed, based on the squadron code letter decal’s tone on the tail.

The roundels and the 'R' codes come from an RBD Studio aftermarket sheet from Sweden, further decals like the yellow ‘9’ code, the squadron’s ‘Bonzo’ dog mascot emblem as well as most stencils come from a Heller SAAB 21.

  

A complex build, yet the model aircraft looks so innocent… Anyway, the goal was IMHO achieved: this J27 model just looks like a “Swedish Spitfire with a P-51 radiator”, and at first glance you cannot be certain if this is a modified Griffon Spitfire or a P-51D. Both is true, to a certain degree, but also not correct, because the changes are more fundamental and the wings are completely different from either. So, the mission’s been accomplished. ;)

 

And I feel inclined to tackle a J23, too, a Bf109/P-51B design hybrid that was designed as a conservative alternative to the pusher J21.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

  

Some background:

The Lockheed Martin (originally developed by General Dynamics) F-16 Fighting Falcon is originally a single-engine multirole fighter aircraft, developed for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,500 aircraft have been built since production was approved in 1976. Although no longer being purchased by the U.S. Air Force, improved versions are still being built for export customers.

 

One of these recent developments is the AF-16 “Strike Falcon”, a thorough update of the original fighter design as a 4.5 generation aircraft and optimized for the attack role. The prototype was presented to the public at the 2012 Singapore Air Show, and the type is intended for the export market as a simpler and less costly alternative to the F-35 multi role SVTOL aircraft.

 

Compared to the original F-16 fighter the new attack aircraft underwent considerable modifications – the most obvious is a new wing with more area (effectively, almost doubling it) and a much thicker profile, a V-tail layout and a fixed Divertless Supersonic Intake (DSI).

 

The AF-16’s new delta wing was designed around a large single piece of carbon fiber composite material. The wing has a span of 11 meters, with a 55-degree leading edge sweep and can hold up to 20,000 pounds of fuel – extending range and loitering time considerable. The purpose of the high sweep angle was to allow for a thick wing section to be used while still providing limited transonic aerodynamic drag, and to provide a good angle for wing-installed conformal antenna equipment.

 

Another side effect of the new wing’s shape is a highly reduced radar signature, which was further improved by the angular, canted twin tail fins and the DSI’s design that absorbs much of incoming frontal radar beams and totally blocks the moving parts of the jet engine.

 

A simple afterburner nozzle for the F110-GE-100 afterburning turbofan was retained, even though a 2D and even 3D vectoring thrust nozzle could be mounted.

The AF-16 features the same AN/APG-68 of the F-16C/D Block 25, but it has been optimized for the ground attack role, even though air combat capabilities are retained. This includes improved ground-mapping, Doppler beam-sharpening, ground moving target indication, sea target, and track while scan (TWS) for up to 10 targets.

 

The system provides all-weather autonomous detection and targeting for Global Positioning System (GPS)-aided precision weapons, SAR mapping and terrain-following radar (TF) modes, as well as interleaving of all modes. The system is also fully compatibility with Lockheed Martin Low-Altitude Navigation and Targeting Infra-Red for Night (LANTIRN) system, which was integrated into the forward fuselage (instead of pods on the F-16).

 

The AF-16 quickly attained interest, and one of the first countries to order the Strike Falcon is Jordan. Jordan gained independence in 1946, but its first air bases had been set up in 1931 by the Royal Air Force. By 1950, Jordan began to develop a small air arm, which came to be known as the Arab Legion Air Force (ALAF).

 

In July of 1994, King Hussein of Jordan signed a peace treaty with Israel, ending over 40 years of hostility between these two nations. Shortly thereafter, the government of Jordan began to lobby within the American government to purchase as many as 42 F-16A/B Fighting Falcons.

 

In recent years, U.S. military assistance has been primarily directed toward upgrading Jordan’s air force, as recent purchases include upgrades to U.S.-made F-16 fighters, air-to-air missiles, and radar systems.

 

Following the 1994 Israel–Jordan peace treaty and the lending of Jordanian support to the United States during the Persian Gulf War, the U.S. recommenced full military relations with Jordan starting with the donation of 16 General Dynamics F-16 Fighting Falcon (12 F-16A and 4 F-16B) in storage at the Aerospace Maintenance and Regeneration Center (AMARC) at Davis Monthan AFB. Deliveries commenced in 1997 and were completed the following year, replacing the Mirage F1CJs in the air-defense role.

 

Other types, especially the ageing F-5E/F fleet, needed replacement, too. The RJAF’s F-5E/F, as well as the remaining Mirage F.1s in the ground support role, took several years after the F-16’s arrival until the AF-16A could finally fill this gap in the RJAF’s arsenal. Fourteen machines had been ordered in 2012 (twelve AF-16A single seaters plus two AF-16B two seaters for conversion training) and were delivered in early 2015, allocated to No. 1 Squadron at Azraq. For twelve more an option had been agreed upon, while the RJAF F-16As will focus on the interceptor and air superiority role.

The kit and its assembly:

This whif kitbashing was inspired by real design studies from General Dynamics that show evolutionary developments of the F-16 in a no-tail configuration, but with an enlarged diamond-shaped wing shape (much like the F-22's), obviously based on the F-16XL. Additionally you find several similar fantasy CG designs in the WWW – the basic idea seems to have potential. And when I stumbled across the remains of a Revell X-32 in my stash and an Intech F-16A kit, I wondered if these could not be reasonably combined...?

 

What sounds easy eventually ended up in a massive bodywork orgy. The Intech kit (marketed under the Polish Master Craft Label) is horrible, the worst F-16 kit I have ever seen or tried to build - it's cheap and you get what you pay for. Maybe the PM Model F-16 is worse (hard to believe, but sprue pics I saw suggest it), but the Intech kits are …challenging. This thing is like a blurred picture of an F-16: you recognize the outlines, but nothing is sharp and no part matches any other! Stay away.

 

Well, actually only the fuselage, the cockpit and parts of the Intech kit's landing gear survived. The X-32 kit is, on the other side, a sound offering. It was not complete anymore, since I donated parts like the cockpit and the landing gear to my SAAB OAS 41 'Vيًarr' stealth aircraft from Sweden some time ago, but there were many good parts left to work with.

 

Especially the aerodynamic surfaces (wings and V-tail) attained my interest: these parts match well with the F-16 fuselage in size and shape if you look from above, and the leading edges even blend well with the F-16 LERXs. But: the X-32's wings are much, much thicker than the F-16's, so that the original blended wing/fuselage intersection does not match at all.

 

Additionally, the X-32's bulged landing gear wells in the wings had to go, so these had to be filled as an initial step. The wing roots were roughly cut into the F-16 kit's shape and glued onto the fuselage. After drying, the whole blended wing/fuselage intersection had to be sculpted from scratch - several layers of putty and even more wet sanding sessions were necessary. I stopped counting after turn five, a tedious job. But it eventually paid out…

 

Furthermore decided to change the F-16's chin air intake and implant parts from the X-32 divertless supersonic "sugar scoop" intake. Such an arrangement has actually been tested on an F-16, so it's not too far-fetched, and its stealthy properties make a welcome update. The respective section from the X-32's lower front fuselage was cut away and had to be modified, too, because it would originally not fit at all under the F-16's front. The intake was carefully heated at the edges and the side walls bent inwards - I was lucky that no melting damage occurred! Inside of the new intake, the upper, bulged part was implanted, too, so that in real life the jet engine parts would be protected from direct frontal radar detection.

 

The front wheel position was retained. As a consequence of the new, much more voluminous and square air intake, the rather round section from the main landing gear onwards had to be sculpted for a decent new fuselage shape, too. But compared to the massive wing/fuselage body work, this was only a minor task.

 

The F-16A's fuselage was not extended, but for a different look I decided to eliminate the single fin and rather implant the X-32's outward-canted twin fins - the original extensions that hold the F-16's air brakes and now blend into the new wings' trailing edge were a perfect place, and as a side benefit they'd partly cover the jet nozzle. The latter was replaced by a respective spare part from an Italeri F-16 – the Intech nozzle is just a plain, conical tube!

 

The landing gear was mostly taken over from the Intech F-16, even though it is rather rough, as well as the pylons. The ordnance was puzzled together: the Sidewinders and the cropped drop tanks come from the Intech kit (the latter have a horribly oval diameter shape and the triangulare fins are a massive 1mm thick!), the Paveway bombs come from a Hasegawa air-to-ground weapons set.

  

Painting and markings:

The livery is somewhat inspired by a CG illustration of a fictional Big-Wing-F-16IN in Jordan colors. I also found a desert camouflage rather interesting for this aircraft – F-16s are typically grey-in-grey, with rare exceptions. Anyway, the paint scheme I applied is pure fiction fictional. I wanted a multi-color scheme with rather sober and subdued colors, partly inspired by contemporary Iranian MiG-29s.

 

I ended up with three upper and a single lower tone. The scheme is roughly based on the pattern that is applied to Venezuelan F-16s, but with desert colors: these are a pale, yellow-ish sand (Humbrol 103, Cream), a medium sand brown (Humbrol 187, Dark Stone) and a dull medium grey (Revell 75, RAL 7030). The undersides were painted in a pale blue (Humbrol 23, RAF Duck Egg Blue).

 

Since a lot of the (already rather vague) surface details of the Intech kit was lost through sanding, I simulated panels through dry painting, later some panel lines were manually added with a pencil, too. A light weathering was done with a thin black in wash. The cockpit was painted in Neutral Grey (FS 36173), and the canopy was tinted with a thinned mix of clear brown and yellow – and it turned out nicely! Even though the rear part had to be painted over, because the clear part’s fit with the rest of the fuselage was poor and putty had to be used to fill gaps and sculpt a decent rear end.

 

Most of the decals come from a Mirage F.1 decal sheet from FFSMC Productions, a French manufacturer. Together with the pale desert colors and the subdued RJAF markings, the AF-16A looks better and more coherent than expected, esp. after a uniform coat of matt acrylic varnish had been applied (from a rattle can).

  

A bold idea, with many doubts on the way, esp. because of the massive body sculpting. But once the kitbashed model was painted and sealed under matt varnish, things suddenly looked pretty cool – a positive surprise. Even though I will certainly never ever touch an Intech F-16 again…

Some background:

The Parder was a successor of the Tiger I & II tanks, combining the latter's thick armor with the armor sloping used on the Panther medium tank (which was, in fact, inspired by Soviet designs, most of all by the T-34). While several Entwicklungspanzer designs were under development, the Parder was a short-term attempt to overcome the Tiger II's main shortcoming: its weight of almost seventy metric tons (it was protected by up to 180 mm/7.1" of front armor!), the resulting lack of mobility and an overburdened drivetrain originally intended for a lighter vehicle. Leaking seals and gaskets also took their toll on reliability.

 

In order to keep the development phase short the Parder used basically the same chassis as the Tiger II, as well as the engine, transmission and the long barreled 8.8 cm KwK 43 L/71 gun. But it reveiced a new hull with optimized armor and many detail modifications that reduced the overall weight by more than ten tons, getting overall weight back to the level of the Tiger I

 

The SdKfz. 190 used a conventional hull design with sloped armor from all sides, resembling the layout of the T-34 a lot. Its was so effective that the front armor could be reduced to 120 mm (4.7 in) with only little loss in protection. The crew was reduced to four, only the driver remained in the hull and the front machine gun was omitted, too.

 

The 'Parder' (archaic German term for leopard), how the vehicle was semi-officially christened by the Entwicklungskommission Panzer, had a rear mounted engine and used nine steel-tired overlapping road wheels per side with internal springing, mounted on transverse torsion bars.

 

The turret had been designed by Krupp and featured a rounded front and steeply sloped sides, with a difficult-to-manufacture curved bulge on the turret's left side to accommodate the commander's cupola (often related to as the "Porsche" turret). The powerful 8.8 cm KwK 43 L/71 gun was combined with the Turmzielfernrohr 9d (German "turret telescopic sight") monocular sight by Leitz - a very accurate and deadly weapon.

 

During practice, the estimated probability of a first round hit on a 2 m (6 ft 7 in) high, 2.5 m (8 ft 2 in) wide target only dropped below 100 percent at ranges beyond 1,000 m (0.62 mi), to 95–97 percent at 1,500 metres (0.93 mi) and 85–87 percent at 2,000 m (1.2 mi), depending on ammunition type. Recorded combat performance was lower, but still over 80 percent at 1,000 m, in the 60s at 1,500 m and the 40s at 2,000 m.

 

Penetration of armored plate inclined at 30 degrees was 202 and 132 mm (8.0 and 5.2 in) at 100 m (110 yd) and 2,000 m (1.2 mi) respectively for the Panzergranate 39/43 projectile (PzGr—armor-piercing shell), and 238 and 153 mm (9.4 and 6.0 in) for the PzGr. 40/43 projectile between the same ranges. The Sprenggranate 43 (SpGr) high-explosive round was available for soft targets, or the Hohlgranate or Hohlgeschoss 39 (HlGr—HEAT or High explosive anti-tank warhead) round, which had 90 mm (3.5 in) penetration at any range, could be used as a dual-purpose munition against soft or armored targets.

 

Like all German tanks, the Parder had a gasoline engine; in this case the same 700 PS (690 hp, 515 kW) V-12 Maybach HL 230 P30 which powered the Panther, Tiger I and Tiger II tanks. The Tiger II was under-powered with it, though, and consumed a lot of fuel, which was in short supply for the Germans, but in the Parder it proved to be adequate, even though performance was not oustanding. The transmission was the Maybach OLVAR EG 40 12 16 Model B, giving eight forward gears and four reverse, which drove the steering gear.

 

In order to distribute the tank's weight an extra wide track was used, but this meant that each tank was issued with two sets of tracks: a normal "battle track" and a narrower "transport" version used during rail movement. The transport tracks reduced the overall width of the load and could be used to drive the tank short distances on firm ground.

 

The Parder was, like many German late war designs, rushed into combat, but thanks to its Tiger I & II heritage many mechanical teething problems had already been corrected. Reliability was considerably improved compared to the much heavier Tiger II, and the Parder did prove to be a very effective fighting vehicle, especially in a defensive role. However, some design flaws, such as its weak final drive units, were never corrected due to raw material shortages, and more tanks were given up by the crews than actually destroyed in combat.

 

The Parder was issued to heavy tank battalions of the Army (Schwere Heerespanzerabteilung – abbreviated s.H.Pz.Abt) where it replaced the Tiger I & II.

The kit and its assembly:

Something different… a whif tank! This was spawned from curiosity and the “wish” to build a German vehicle that would fit right into the E-25… E-100 range of experimental tanks.

It was to become a battle tank, and while browsing options and donation kits, I settled upon a replacement for the formidable but heavy and cumbersome Tiger B, also known as Tiger II, Königstiger or (wrongfully translated) King Tiger.

 

Anyway, creating a tank that would look (late war) German and still be whiffy was trickier than expected, and finally easier than expected, too. My solution would be a kit bashing: using many Tiger B parts (including the stylish Porsche tower and the running gear) and combining it with a hull that would offer better armor angles and look less “boxy”.

 

I effectively bashed two kits: one is the excellent 1:72 early Tiger B from Dragon, the other is Roden’s Soviet IS-3 tank – also very nice, even though the styrene is somewhat brittle.

 

My biggest fear was the running gear – combining the IS-3 hull with the Tiger B’s totally different legs scared me a lot – until I found that the parts from both kits (the Tiger B’s lower hull with all the suspension and the IS-3’s upper hull) could be combined rather easily combined. Just some cuts and improvised intersections, and the “new” tank hull was done!

 

As a side effect, the huge turret moved forward, and this considerably changes the silhouette. The IS-3’s opening had only to be widened slightly in order to accept the Porsche turret. Things matched up pretty well, also concerning size and proportions.

 

Otherwise, not much was changed. All wheels and tracks come from the Trumpeter Tiger B, the turret was also borrowed wholesale. I just changed some details (e. g. moving the spare track elements to the hull front), added some handles and also a heavy AA machine gun on the commander’s cupola, which is OOB, too.

 

Too simple? Well, for me it was not enough. For a more personal edge to the kit I decided to add Thoma skirts! Not the massive 5mm plates you frequently see on late Panzer IV tanks and its derivatives, rather the mesh type – lighter, less material-consuming, and a very special detail.

 

These were scratched. There are PE sets available, but that was too expensive and I was not certain if such items would fit in shape and size? So I made a cardboard template for the flanks and built a pair of skirts from styrene strips and a fine PET mesh that I had salvaged from a wallet long time ago.

 

The stuff is hard to glue onto something, so the styrene frame had to carry the mesh parts – and it works! The attachments to the hull were also scratched from styrene.

The Thoma shields add more width to the flat tank, but I think that they set the kit even more apart than just the borrowed IS-3 hull?

  

Painting and markings:

Hmmm, not totally happy with the finish. This was supposed to become a simple Hinterhalt (Ambush) paint scheme in Dark Yellow, Olive Green and Red Brown, but I did so much weathering that not much from the scheme can be recognized…

 

Painting was straightforward, though – I used Humbrol 94 and 173 as well as Modelmaster’s RAL 6003 as basic colors. The scheme’s benchmark is the official Tiger B scheme.

 

The basic colors received mottles in green on the yellow and yellow on the green and brown, and then the thing was thoroughly weathered with a black ink wash, dry-brushing, some aquarelle paint to simulate dust, and finally some pigments that simulate mud.

 

The tracks are made from soft vinyl, and also received a paint treatment in order to get rid of that shiny vinyl look: at first, with a mix of black and silver, which was immediately wiped off again, and later with a second, similar turn with silver and dark brown.

 

The mud was added just before the whole running gear was mounted as one of the final assembly stages, and final retouches were made with acrylic umbra paint.

 

Alas, I think I overdid it – much of the formidable and very attractive paint scheme was lost, even though the yucky, brownish finish now also works fine and looks like rough duty?

  

So, an experiment with good and bad results. Certainly not the last whif tank (at least one more on the agenda), and after so many aircraft a new kind of challenge. ^^

made some new BSAA patches today, they're a little bit clearer than the last ones I had, also added the patches on the vest's admin panel, I've got to get a long sleeve OD jacket type shirt for this figure to look like he does in game, I also need another one of those sideshow acr rifles, but I'm pretty happy with this too, added some zombie like details to one of my diorama walls, I wish I could get a decent picture of the figure and the signs I put in the background I think they really add to the scene, maybe I can get some better shots in the daylight tomorrow

How it came to be:

It has been a long time since I built a "real" airplane kit, and this one here is a one-of-a-kind. After a bleak phase with lots of reading about German WWII airplane projects I found a spark to fire up a project I kept in the back of my mind for a long time: building one of these semi-fictional WWII airplanes from scratch. These astonishing designs were on the drawing boards at their time and rarely made it beyond that. Only a few reached prototype status at the end of the war, but today these partly weird designs are the basis of today's Luft '46 model kit genre: What-if airplanes, based on sketches, construction plans and pure speculation, in the case the war would have gone on.

 

At this point I want to make clear that this kit has NO political background. It is not even intended, and any Nazi symbolism is intentionally avoided and rejected. It is rather a hommage to an impressive design and, from my personal point of view, pure science fiction, based on vague historic facts.

 

Some historic background on this plane:

This plane is a Focke-Wulf study from 1941 for a heavy fighter. It was developes shortly after the Fw 190 introduction and surely influenced by the twin-boom Fw 189 reconnaissance aircraft, which became very popular due to its high agility, stable flight characteristics and toughness against enemy fire. The small "Flitzer" turbine engine fighter will surely also have had some impact, since it was on Focke Wulf's drawing boards in 1943, too.

 

This beast here would have been a much larger airplane, though: a heavy, high performance fighter built around the potent BMW 803 engine: a 28 cylinder, liquid-cooled radial engine in the 4.000 hp output range - comparable to the P&W-R-4360 Wasp Major engine (the so-called "corncob") which actually found its way into the Vought F2G Corsair but "just" put out 3.000 hp.

For reference, this Focke Wulf design was quite comparable to the US American XP-54, both in design and performance

 

The Focke Wulf fighter never received an official designation, and saw some mutation in the course of 1943. Even though the basic layout as a twin-boom, single pusher engine airplane with a tricycle landing gear was retained, the radiator placements, wing and tail shape changed.

From the original 1941 annular radiator design (a ring opening around the central fuselage), the arrangement was modified in April 1943 to a single drum radiator in the nose and, alternatively, twin drum radiators in the front ends of the tailbooms. The latter design is the layout I chose for my model, or better: where I ended up (see below).

A nice reference archive, since a lot information concerning colors can be found there, too. Handling is poor, though. But once you get it, it is a great model kit building source.

  

The construction:

Anyway, this Focke Wulf design never left the drawing board, and this model here is just an interpretation of the vague design sketches I found in literature. It is also limited by the use of various existing kits as a kitbashing basis. My idea was to build a what-if version of the airplane if it had entered service, which would allow some deviations from the blueprints and also leave some room for a semi-realistic Luftwaffe livery.

 

What went into this model:

 

Grumman Panther (1:72, Matchbox/Revell):

- Main body,

- Parts of the outer wings

- Cockpit interior

- Canopy

 

Lockheed P-38E Lightning (1:72; Airfix):

- Tailbooms

- Horizontal fin

- Cockpit parts

- Landing gear

- Propeller spinners

 

Messerschmidt Me 262 A-2a (1:72, Hobby Master):

- Outer wings

- Wheels

 

Dornier Do 217N (1:72, Italeri):

- Engine cowling (rear central fuselage)

- Propellers

 

Other smaller donations:

- Kamow Ka-25 (1:72, Airfix): Vertical fins

- Chance Vought XF5U-1 (1:72, Hasegawa): Propeller spinners

- Chance Vought F4U (1:72, Matchbox): Engine block

- Messerschmidt Me-110 (1:72, Matchbox): Pilot figure

...and a lot of small stuff of unknown origin!

  

Laying the foundations

The basic choice for donation kits was quickly done: the central body would come from the Grumman F9F-4 Panther kit from Matchbox (currently released by Revell). Its overall proportions match well with the Focke Wulf design's central body and its size well, and the kit's construction with folded wings and a separate tail fin allowed easy modification for the pusher engine layout.

 

Originally, I wanted to use the Panther's jet intakes as radiator openings for a fictional (and more elegant) design alternative to the "official" radiator solutions, but I had to skip this idea (see below). The slender tailbooms come from a vintage Airfix P-38H kit and are much more slender than the Focke Wulf designs. Furthermore, the original Focke Wulf main landing gear looks as if it would retract inwards - which collided with my intial radiator ideas! Due to the pusher propeller, a much longer landing gear than the Panther's wpould be necessary, and this would have needed much bigger compartments. Enlarging them appeared too complex, and there's be actually no space with my inital wing root radiator idea. Therefore, I decided to retract the main wheels into the twin booms, and the P-38 pieces were just perfect for my ideas (and at hand). They'd undergo major modifications, though.

 

The twin booms were to be mounted onto the Panther's inner wings, and from there the rest of the model design would come when the parts were needed or available, since matching proportions for a balanced look is an important aspect when you build from scratch - a lesson I learned through varioius mecha bashings and modifications. I had some plans though: for the outer wings, for instance, I considered straight wings from a Fw 190 or parts from a Do 335 "Arrow", since these are slightly swept and would match the original drawings quite well.

  

The body parts get assembled

Work started straightforward with the tailbooms: they needed total cleaning, so that the P-38 look would disappear as much as possible: intercooolers and turbochargers had to go, and the engines were to "disappear", too. The Airfix kit is pretty old and clumsy, but offers massive material to work with. Another positive aspect is that the main landing gear compartments are complete parts, including the doors and all the inside. A neat arrangement which would later allow a switch between extended and retracted wheels!

 

The Panther's fuselage was cut open at the rear end to hold the BMW 803 engine, which requiered a new cowling. This came from a Dornier Do 217 with BMW 801 engines from Italeri, the BMW 803 dummy inside comes from a Matchbox F4U kit. The diameters of both segments were pretty equal and were easily merged with putty.

 

The Panther's front end was taken as it is, including the cockpit. The latter is actually very detailed for a Matchbox kit, with side consoles, a dashboard with instruments and even steering stick is included. I just fitted a better seat and a WWII pilot figure, which received an oxygen mask and its head was turned left for a more vivid look.

 

Since the front wheel had to be much longer than the Panther pieces I decided to use the P-38 front landing gear. Consequently, I enlarged its compartment (towards the nose, with a transplanted interior) and moved the Panther's nose guns from their original low position upwards. The kit's nose was filled with lots of lead in order to ensure a good weight on the front wheel for free standing on its tricycle undercarriage.

 

The BMW 803's contraprops had to be built from scratch. The basis were two leftover three-bladed rotors from the aforementioned Do 217 Italeri kit (they had just the correct diameter!) for the static display version, and two transparent plastic discs of the same diameter in order to mimic running propellers for photo shooting purposes in flight.

The spinners were a nightmare, though. They come from a wrecked 1:72 Hasegawa kit of a Chance Vought XF5U-1 (The "Flying Pancake"). Cut into three pieces, the three-bladed props were implanted into the spinner segments and a metal axis inserted, so that the propellers can be moved and interchanged. A plastic tube inside of the engine dummy is the respective adapter and offers a stable hold.

  

Trouble! ...and even more trouble!

As rough work progressed, some fundamental problems became obvious:

 

a) the P-38 booms were too long at their front, and their diameter was much too large. Cutting the front ends off did not help much, since I would have had to create new front covers/noses from putty and their bulky shape would look very unsinspired - way off of the Focke Wulf design! Hence, I finally decided to switch my personal design plan from the wing root intake arrangement to the authetic twin drum radiator layout from April 1943.

The Panther's air intakes would be totally closed, leaving pretty "fat" wing roots of high thickness. But since armament was supposed to be loacted in both the nose and wing roots of this machine (see below), this offered a good chance to cover the mess up a little.

Finding something to act as drum radiators was another problem that followed suit! At first I thought I'd become happy with two leftover engines from a Matchbox PB4-Y2 Privateer in 1:72 scale. These are/were actually Twin Wasp radial engines, but their diameter, the grates inside and their cooling flaps made them suited for my kit. They fitted well, but it just did not look right (see some of the WIP pics).

Heavy-hearted I skipped this approach and also built the drums radiators from scratch. I finally found some good parts in model railraod equipment: in a HO Modulars set from Cornerstone with various roof detils for industrial buildings, I found two nice "tubs" (parts for motorized vents) which were merged with lots of putty and sanding onto the clipped tail booms. The radiator arrangement inside was made up from parts from a 1:72 scale Panzer IV(!) and from the Airfix P-38 spinners. The cooling flaps are very thin Plasticard. Comparing this solution with the original plane sketches, the result looks convicing and more "realistic" than originally planned! Whew...

 

b) The wing root/twin boom area was another source of headaches, since I had to merge parts that were never supposed to meet, in places even less intended for construction. But a mini drill with a diamond cutter and epoxy putty are wonderful things!

Spacers between the Panther hull and the booms had to be made, closing a 5mm gap on each side because the propeller needed this much space between the booms. Parts of the leftover Panther kit's outer wings were the basis, and the original P-38's horizonmtal fin could be used, too. Sound simple, but almost the complete area had to be remodeled with putty.

  

The big picture becomes clear(er)

Now that the main part of the body was finished, the final missing pieces could be added and first details defined.

 

For the outer wings, I finally settled on parts from a Me 262 from Hobby Boss. These have the advantage that they are massive pieces (not two halves, as usual) and that the Me 262's engine nacelles could easily be left away. As a result, I had two thin, slightly swept wings which could easily be cut into the right length for my project. Fixing them to the P-38 tail booms was another story, though!

The original Focke Wulf design uses simpler and thicker wings, which look very similar to the Do 335. But I justify my choice with the advancements in aerodynamics since the 1943 revision of the original plane's design and the effective introduction of the Me 262 into production and service. Using these parts or a similar design for high speeds in another airplane appears plausible in order to get this machine into the air quickly, and the slender Me 262 wings blend well with the angles of the inner wings from the Panther.

 

The vertical fins also puzzled me for some time. The round P-38 fins had definitively to go, but the different Focke Wulf design sketches did not show a definitive vertical fin shape or arrangement. Since I wanted an old-fashioned, not jet-like look, I went for parts from the scrap box again. And, believe it or not, the model's retro-looking vertical fins actually come from a helicopter: from an antique 1:72 scale Kamow Ka-25 "Hokum" from Airfix!

 

The main landing gear was taken from the P-38, but the wheels come from the scrap box. I am not sure where these come from - they could come from a Douglas Skyknight from Matchbox. Since the Airfix kit's contruction offers the main landing gear to be inserted as complete units, I also used the covers for the retracted gear for the photo shootings, for some pictures in flight.

  

Armament:

Being a heavy daylight fighter, I stuck to the original 1941 design armament: four fixed 20mm MG 151/20 in the nose, plus "provision for two larger calibre cannons", plus two or four machine guns installed in the wing-roots. The firepower would have been massive!

 

For my model I adopted the four 20mm guns in the upper nose and added four 30mm MK 103 cannons in the wing roots. Since these offered now lots of space, this arrangement would make the thick wing and the blended bodywork plausible, without looking exagerrated.

The nose guns are just thin polystyrol sticks, the larger calibre guns are syringe needles cut to length with the beloved diamond cutter.

 

But beyond the guns, I also wanted to add some of the experimental air-to-air weapons that were under development against allied bomber forces in 1945. Among those was the world's probably first guided AAM, the Kramer X-4: a relatively small, wire-guided missile with a range of just 3 miles and a contact detonator.

Tests with this innovative weapon were conducted in the late war months, and the X-4 was suppoesed to be carried by e. g. Me 262 fighters. The targeting procedure would easily overstress a single pilot's capabilities, though, esp. in the heat of a bomber formation attack at high speeds. Therefore, field tests were rather performed by multi-seated planes like the Ju 88, and the X-4 did not enter serious service.

But this missile would have been a plausible weapon for this Focke Wulf design, and so two X-4s found their way with starting racks under my model's wings.

Each missile consists of nine parts and had to be built from scratch. The body is a streamlined, modern 250 lbs. Mk 81 bomb, the wings were cut from thin polystyrol. The wire spools on the wing tips are actually parts from a HO scale fence(!), the acoustic detonator nose are leftover tool handles from a 1:35 scale tank kit.

  

Livery and markings:

Being a semi-fictional design that never left the drawing board, I tried to implement a "typical" late war Luftwaffe livery. Benchmarks were Me 262 fighter paint schemes, as well as late Fw 190D-9 and Ta-152 machines. Since the plane itself was already centre of attraction, the paint job should be rather subtle, yet authentic.

 

All interior areas (cockpit, engine, landing gear) were painted in RLM 02. For the outside I ended up with a basic livery in RLM 74/75/76, using colors from Testor's Military Models and Figures range, 2071, 2084, 2085, 2086.

The upper splinter scheme with faded/mottled fuselage sides (which includes RLM 02 in order to create a soft color transition from the dark upper sides into the light RLM 76 underneath, a common practice in field conditions) was derived from a Me 262 profile. This machine also contributed the dark green (RLM 82) color fields on the nose and other fuselage parts. These would not have been standard livery, I think, rather improvised in the field. But this subtle detail prevents the plane from being all grey-in-grey.

 

The markings come from various decal sheets and were a kind of challenge. I intended to mark this machine as being part of an Erprobungskommando (test unit), or EKdo or EK, for short. But these squadrons would not have special designations, though. Prototypes woud carry a "V"-number (for Versuch/test), but I wanted a machine already in service. So I made up a semi-fictional squadron marking as a part of the late Reich defense.

 

Typical markings are the colored band at the rear fuselage, its color and scheme being associated with certain Jagdgeschwader (JG) wings, dedicated to interception tasks. The red tail band(s) denote this machine as being part of JG 1, which comprised several Staffeln/groups and squadrons with individual emblems. The JG 1's red tail band would not have been used in the late war years in real life, but, hey, it LOOKS good, and we're finally doing fictional things here! As a side note, JG 1 was the only wing (to be exact: 1./JG 1 and later, in April 1945 III./JG 1) to use the He 162 Salamender jet fighter, so JG 1 appears to be a general plausible choice for this fictional Focke Wulf fighter.

The red wave symbol should, AFAIK, mark the 2nd group of that wing, but it could also be a symbol for the pilot's rank - that's quite obscure and had not been handled consistently. For squadron markings I setlled on 6./JG 1 - the red wyvern was this group's squadron emblem.

 

Decals come from aftermarkets sheet from TL-Modellbau (superb quality) and others i e. from a MiG-25 from Hasegawa (the red bort number) or the leftover decal sheet of the Hobby Boss Me 262 (mostly stencellings and warning signs).

 

After application of the decals on the semi-matte paint, everything was sealed under matte varnish.

 

The X-4 missiles were painted in a color livery I found for a museum X-4. Other test missiles were painted in black and white, checkered. Not sure if the field use missiles would have looked that bright, but for a test unit, the blank fuselage and the hi-vis, orange fins look just right and make a nice contrast to the dull rest of the machine.

  

Finally...

Lots of work, but the result looks better and more harmonious than I expected. O.K., the Panther's fuselage and cockpit deviate from the Focke Wulf sketches - but the plane I built would have had entered service 3 years after its redesign to the drum radiator design, and details like the bubble canopy or more modern weaponry would have certainly been incorporated.

The finish is not as good as a kit "out of the box", but considering the massive putty work, this machine looks quite good :)

 

And, after all, it is a fictional design!

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

 

How it came to be:

It has been a long time since I built a "real" airplane kit, and this one here is a one-of-a-kind. After a bleak phase with lots of reading about German WWII airplane projects I found a spark to fire up a project I kept in the back of my mind for a long time: building one of these semi-fictional WWII airplanes from scratch. These astonishing designs were on the drawing boards at their time and rarely made it beyond that. Only a few reached prototype status at the end of the war, but today these partly weird designs are the basis of today's Luft '46 model kit genre: What-if airplanes, based on sketches, construction plans and pure speculation, in the case the war would have gone on.

 

At this point I want to make clear that this kit has NO political background. It is not even intended, and any Nazi symbolism is intentionally avoided and rejected. It is rather a hommage to an impressive design and, from my personal point of view, pure science fiction, based on vague historic facts.

 

Some historic background on this plane:

This plane is a Focke-Wulf study from 1941 for a heavy fighter. It was developes shortly after the Fw 190 introduction and surely influenced by the twin-boom Fw 189 reconnaissance aircraft, which became very popular due to its high agility, stable flight characteristics and toughness against enemy fire. The small "Flitzer" turbine engine fighter will surely also have had some impact, since it was on Focke Wulf's drawing boards in 1943, too.

 

This beast here would have been a much larger airplane, though: a heavy, high performance fighter built around the potent BMW 803 engine: a 28 cylinder, liquid-cooled radial engine in the 4.000 hp output range - comparable to the P&W-R-4360 Wasp Major engine (the so-called "corncob") which actually found its way into the Vought F2G Corsair but "just" put out 3.000 hp.

For reference, this Focke Wulf design was quite comparable to the US American XP-54, both in design and performance

 

The Focke Wulf fighter never received an official designation, and saw some mutation in the course of 1943. Even though the basic layout as a twin-boom, single pusher engine airplane with a tricycle landing gear was retained, the radiator placements, wing and tail shape changed.

From the original 1941 annular radiator design (a ring opening around the central fuselage), the arrangement was modified in April 1943 to a single drum radiator in the nose and, alternatively, twin drum radiators in the front ends of the tailbooms. The latter design is the layout I chose for my model, or better: where I ended up (see below).

A nice reference archive, since a lot information concerning colors can be found there, too. Handling is poor, though. But once you get it, it is a great model kit building source.

  

The construction:

Anyway, this Focke Wulf design never left the drawing board, and this model here is just an interpretation of the vague design sketches I found in literature. It is also limited by the use of various existing kits as a kitbashing basis. My idea was to build a what-if version of the airplane if it had entered service, which would allow some deviations from the blueprints and also leave some room for a semi-realistic Luftwaffe livery.

 

What went into this model:

 

Grumman Panther (1:72, Matchbox/Revell):

- Main body,

- Parts of the outer wings

- Cockpit interior

- Canopy

 

Lockheed P-38E Lightning (1:72; Airfix):

- Tailbooms

- Horizontal fin

- Cockpit parts

- Landing gear

- Propeller spinners

 

Messerschmidt Me 262 A-2a (1:72, Hobby Master):

- Outer wings

- Wheels

 

Dornier Do 217N (1:72, Italeri):

- Engine cowling (rear central fuselage)

- Propellers

 

Other smaller donations:

- Kamow Ka-25 (1:72, Airfix): Vertical fins

- Chance Vought XF5U-1 (1:72, Hasegawa): Propeller spinners

- Chance Vought F4U (1:72, Matchbox): Engine block

- Messerschmidt Me-110 (1:72, Matchbox): Pilot figure

...and a lot of small stuff of unknown origin!

  

Laying the foundations

The basic choice for donation kits was quickly done: the central body would come from the Grumman F9F-4 Panther kit from Matchbox (currently released by Revell). Its overall proportions match well with the Focke Wulf design's central body and its size well, and the kit's construction with folded wings and a separate tail fin allowed easy modification for the pusher engine layout.

 

Originally, I wanted to use the Panther's jet intakes as radiator openings for a fictional (and more elegant) design alternative to the "official" radiator solutions, but I had to skip this idea (see below). The slender tailbooms come from a vintage Airfix P-38H kit and are much more slender than the Focke Wulf designs. Furthermore, the original Focke Wulf main landing gear looks as if it would retract inwards - which collided with my intial radiator ideas! Due to the pusher propeller, a much longer landing gear than the Panther's wpould be necessary, and this would have needed much bigger compartments. Enlarging them appeared too complex, and there's be actually no space with my inital wing root radiator idea. Therefore, I decided to retract the main wheels into the twin booms, and the P-38 pieces were just perfect for my ideas (and at hand). They'd undergo major modifications, though.

 

The twin booms were to be mounted onto the Panther's inner wings, and from there the rest of the model design would come when the parts were needed or available, since matching proportions for a balanced look is an important aspect when you build from scratch - a lesson I learned through varioius mecha bashings and modifications. I had some plans though: for the outer wings, for instance, I considered straight wings from a Fw 190 or parts from a Do 335 "Arrow", since these are slightly swept and would match the original drawings quite well.

  

The body parts get assembled

Work started straightforward with the tailbooms: they needed total cleaning, so that the P-38 look would disappear as much as possible: intercooolers and turbochargers had to go, and the engines were to "disappear", too. The Airfix kit is pretty old and clumsy, but offers massive material to work with. Another positive aspect is that the main landing gear compartments are complete parts, including the doors and all the inside. A neat arrangement which would later allow a switch between extended and retracted wheels!

 

The Panther's fuselage was cut open at the rear end to hold the BMW 803 engine, which requiered a new cowling. This came from a Dornier Do 217 with BMW 801 engines from Italeri, the BMW 803 dummy inside comes from a Matchbox F4U kit. The diameters of both segments were pretty equal and were easily merged with putty.

 

The Panther's front end was taken as it is, including the cockpit. The latter is actually very detailed for a Matchbox kit, with side consoles, a dashboard with instruments and even steering stick is included. I just fitted a better seat and a WWII pilot figure, which received an oxygen mask and its head was turned left for a more vivid look.

 

Since the front wheel had to be much longer than the Panther pieces I decided to use the P-38 front landing gear. Consequently, I enlarged its compartment (towards the nose, with a transplanted interior) and moved the Panther's nose guns from their original low position upwards. The kit's nose was filled with lots of lead in order to ensure a good weight on the front wheel for free standing on its tricycle undercarriage.

 

The BMW 803's contraprops had to be built from scratch. The basis were two leftover three-bladed rotors from the aforementioned Do 217 Italeri kit (they had just the correct diameter!) for the static display version, and two transparent plastic discs of the same diameter in order to mimic running propellers for photo shooting purposes in flight.

The spinners were a nightmare, though. They come from a wrecked 1:72 Hasegawa kit of a Chance Vought XF5U-1 (The "Flying Pancake"). Cut into three pieces, the three-bladed props were implanted into the spinner segments and a metal axis inserted, so that the propellers can be moved and interchanged. A plastic tube inside of the engine dummy is the respective adapter and offers a stable hold.

  

Trouble! ...and even more trouble!

As rough work progressed, some fundamental problems became obvious:

 

a) the P-38 booms were too long at their front, and their diameter was much too large. Cutting the front ends off did not help much, since I would have had to create new front covers/noses from putty and their bulky shape would look very unsinspired - way off of the Focke Wulf design! Hence, I finally decided to switch my personal design plan from the wing root intake arrangement to the authetic twin drum radiator layout from April 1943.

The Panther's air intakes would be totally closed, leaving pretty "fat" wing roots of high thickness. But since armament was supposed to be loacted in both the nose and wing roots of this machine (see below), this offered a good chance to cover the mess up a little.

Finding something to act as drum radiators was another problem that followed suit! At first I thought I'd become happy with two leftover engines from a Matchbox PB4-Y2 Privateer in 1:72 scale. These are/were actually Twin Wasp radial engines, but their diameter, the grates inside and their cooling flaps made them suited for my kit. They fitted well, but it just did not look right (see some of the WIP pics).

Heavy-hearted I skipped this approach and also built the drums radiators from scratch. I finally found some good parts in model railraod equipment: in a HO Modulars set from Cornerstone with various roof detils for industrial buildings, I found two nice "tubs" (parts for motorized vents) which were merged with lots of putty and sanding onto the clipped tail booms. The radiator arrangement inside was made up from parts from a 1:72 scale Panzer IV(!) and from the Airfix P-38 spinners. The cooling flaps are very thin Plasticard. Comparing this solution with the original plane sketches, the result looks convicing and more "realistic" than originally planned! Whew...

 

b) The wing root/twin boom area was another source of headaches, since I had to merge parts that were never supposed to meet, in places even less intended for construction. But a mini drill with a diamond cutter and epoxy putty are wonderful things!

Spacers between the Panther hull and the booms had to be made, closing a 5mm gap on each side because the propeller needed this much space between the booms. Parts of the leftover Panther kit's outer wings were the basis, and the original P-38's horizonmtal fin could be used, too. Sound simple, but almost the complete area had to be remodeled with putty.

  

The big picture becomes clear(er)

Now that the main part of the body was finished, the final missing pieces could be added and first details defined.

 

For the outer wings, I finally settled on parts from a Me 262 from Hobby Boss. These have the advantage that they are massive pieces (not two halves, as usual) and that the Me 262's engine nacelles could easily be left away. As a result, I had two thin, slightly swept wings which could easily be cut into the right length for my project. Fixing them to the P-38 tail booms was another story, though!

The original Focke Wulf design uses simpler and thicker wings, which look very similar to the Do 335. But I justify my choice with the advancements in aerodynamics since the 1943 revision of the original plane's design and the effective introduction of the Me 262 into production and service. Using these parts or a similar design for high speeds in another airplane appears plausible in order to get this machine into the air quickly, and the slender Me 262 wings blend well with the angles of the inner wings from the Panther.

 

The vertical fins also puzzled me for some time. The round P-38 fins had definitively to go, but the different Focke Wulf design sketches did not show a definitive vertical fin shape or arrangement. Since I wanted an old-fashioned, not jet-like look, I went for parts from the scrap box again. And, believe it or not, the model's retro-looking vertical fins actually come from a helicopter: from an antique 1:72 scale Kamow Ka-25 "Hokum" from Airfix!

 

The main landing gear was taken from the P-38, but the wheels come from the scrap box. I am not sure where these come from - they could come from a Douglas Skyknight from Matchbox. Since the Airfix kit's contruction offers the main landing gear to be inserted as complete units, I also used the covers for the retracted gear for the photo shootings, for some pictures in flight.

  

Armament:

Being a heavy daylight fighter, I stuck to the original 1941 design armament: four fixed 20mm MG 151/20 in the nose, plus "provision for two larger calibre cannons", plus two or four machine guns installed in the wing-roots. The firepower would have been massive!

 

For my model I adopted the four 20mm guns in the upper nose and added four 30mm MK 103 cannons in the wing roots. Since these offered now lots of space, this arrangement would make the thick wing and the blended bodywork plausible, without looking exagerrated.

The nose guns are just thin polystyrol sticks, the larger calibre guns are syringe needles cut to length with the beloved diamond cutter.

 

But beyond the guns, I also wanted to add some of the experimental air-to-air weapons that were under development against allied bomber forces in 1945. Among those was the world's probably first guided AAM, the Kramer X-4: a relatively small, wire-guided missile with a range of just 3 miles and a contact detonator.

Tests with this innovative weapon were conducted in the late war months, and the X-4 was suppoesed to be carried by e. g. Me 262 fighters. The targeting procedure would easily overstress a single pilot's capabilities, though, esp. in the heat of a bomber formation attack at high speeds. Therefore, field tests were rather performed by multi-seated planes like the Ju 88, and the X-4 did not enter serious service.

But this missile would have been a plausible weapon for this Focke Wulf design, and so two X-4s found their way with starting racks under my model's wings.

Each missile consists of nine parts and had to be built from scratch. The body is a streamlined, modern 250 lbs. Mk 81 bomb, the wings were cut from thin polystyrol. The wire spools on the wing tips are actually parts from a HO scale fence(!), the acoustic detonator nose are leftover tool handles from a 1:35 scale tank kit.

  

Livery and markings:

Being a semi-fictional design that never left the drawing board, I tried to implement a "typical" late war Luftwaffe livery. Benchmarks were Me 262 fighter paint schemes, as well as late Fw 190D-9 and Ta-152 machines. Since the plane itself was already centre of attraction, the paint job should be rather subtle, yet authentic.

 

All interior areas (cockpit, engine, landing gear) were painted in RLM 02. For the outside I ended up with a basic livery in RLM 74/75/76, using colors from Testor's Military Models and Figures range, 2071, 2084, 2085, 2086.

The upper splinter scheme with faded/mottled fuselage sides (which includes RLM 02 in order to create a soft color transition from the dark upper sides into the light RLM 76 underneath, a common practice in field conditions) was derived from a Me 262 profile. This machine also contributed the dark green (RLM 82) color fields on the nose and other fuselage parts. These would not have been standard livery, I think, rather improvised in the field. But this subtle detail prevents the plane from being all grey-in-grey.

 

The markings come from various decal sheets and were a kind of challenge. I intended to mark this machine as being part of an Erprobungskommando (test unit), or EKdo or EK, for short. But these squadrons would not have special designations, though. Prototypes woud carry a "V"-number (for Versuch/test), but I wanted a machine already in service. So I made up a semi-fictional squadron marking as a part of the late Reich defense.

 

Typical markings are the colored band at the rear fuselage, its color and scheme being associated with certain Jagdgeschwader (JG) wings, dedicated to interception tasks. The red tail band(s) denote this machine as being part of JG 1, which comprised several Staffeln/groups and squadrons with individual emblems. The JG 1's red tail band would not have been used in the late war years in real life, but, hey, it LOOKS good, and we're finally doing fictional things here! As a side note, JG 1 was the only wing (to be exact: 1./JG 1 and later, in April 1945 III./JG 1) to use the He 162 Salamender jet fighter, so JG 1 appears to be a general plausible choice for this fictional Focke Wulf fighter.

The red wave symbol should, AFAIK, mark the 2nd group of that wing, but it could also be a symbol for the pilot's rank - that's quite obscure and had not been handled consistently. For squadron markings I setlled on 6./JG 1 - the red wyvern was this group's squadron emblem.

 

Decals come from aftermarkets sheet from TL-Modellbau (superb quality) and others i e. from a MiG-25 from Hasegawa (the red bort number) or the leftover decal sheet of the Hobby Boss Me 262 (mostly stencellings and warning signs).

 

After application of the decals on the semi-matte paint, everything was sealed under matte varnish.

 

The X-4 missiles were painted in a color livery I found for a museum X-4. Other test missiles were painted in black and white, checkered. Not sure if the field use missiles would have looked that bright, but for a test unit, the blank fuselage and the hi-vis, orange fins look just right and make a nice contrast to the dull rest of the machine.

  

Finally...

Lots of work, but the result looks better and more harmonious than I expected. O.K., the Panther's fuselage and cockpit deviate from the Focke Wulf sketches - but the plane I built would have had entered service 3 years after its redesign to the drum radiator design, and details like the bubble canopy or more modern weaponry would have certainly been incorporated.

The finish is not as good as a kit "out of the box", but considering the massive putty work, this machine looks quite good :)

 

And, after all, it is a fictional design!
