Some background:
The Fokker D.XX fighter was designed in 1935 by Dutch aircraft manufacturer Fokker as a conservative export alternative to the D.XXI monoplane. The latter had been developed in response to requirements laid out by the Royal Netherlands East Indies Army Air Force (Militaire Luchtvaart van het Koninklijk Nederlands-Indisch Leger, ML-KNIL), but Fokker saw a good deal of market potential for the aircraft in Europe, too, but was afraid that many smaller European air forces still preferred conservative biplane designs.
As a consequence, the D.XX was developed in parallel to the D.XXI and both aircraft shared many components, primarily the fuselage and the tail section. Like its D.XXI stablemate the D.XX biplane was designed as an inexpensive, rugged, and compact fighter aircraft that would possess respectable performance for its era.
Following standard Fokker design practice of the period, the D.XX featured a welded steel tube fuselage that was largely covered by fabric, including the flight control surfaces, but elements forward of the trailing edges of the wings were covered by detachable aluminum panels instead. The wings were of a wooden construction, being composed of two box spars attached to ribs made of plywood, and covered by fabric, too. The aircraft was outfitted with a fixed, spatted undercarriage with cantilever legs, and braking was provided by independently-operated pedals using compressed air.
The cockpit of the D.XXI was fully enclosed by a plexiglas hood featuring large sliding sections. The canopy was entirely jettisonable in an emergency situation to enable pilots to bail out. Pilots were protected against turnover injuries by means of a pylon built into the structure of the aircraft set behind the seat. Fuel was housed in a 77-gallon tank located aft of the engine, and an auxiliary fuel tank could also be installed behind the pilot seat.
Main armament consisted of two pairs of 7.92mm M36 FN-Browning machine guns, two being housed within the forward fuselage above the engine, requiring the latter to be synchronized in order to shoot through the propeller blades, and another pair was carried in fairings under the lower wings, outside of the propeller arc.
Initially, the Fokker D.XX was powered by the 830 h.p. Bristol Mercury VII or VIII engines, but for export customers a number of alternative engines were considered, too. These included such power plants as the 650 h.p. Rolls-Royce Kestrel V and the 750 h.p. Pratt and Whitney Twin Wasp Junior. There were even plans to mount the 1,050 h.p. Rolls-Royce Merlin and the 1,090 h.p. Daimler-Benz DB 600H, both coupled with a radiator installation under the fuselage.
However, interest in the Fokker D.XX was low, since the monoplane promised much superior performance and future development potential. Compared with the Fokker D.XXI, the D.XX lacked top speed and acceleration, but it had, thanks to its much bigger wing area, a better rate of climb and was the superior dogfight aircraft.
Anyway, with the D.XXI as direct in-house competitor and very similar aircraft like the Gloster Gladiator on the market, Fokker's last biplane aircraft was not a success. A major contract with Sweden for an initial batch of 30 aircraft and rights for further license production did not materialize. Other prospects, e. g. Lithuania, Latvia, Greece, Egypt and Yugoslavia, settled upon aircraft of British production, and in the end only Norway and Denmark bought the biplane fighter.
Total production, including two prototypes and three pre-production aircraft, only reached a mere 46 machines, and none of them survived the first months of the 2nd World War.

The kit and its assembly:
I had found the spare wings from a Gloster Gladiator in my donor bank, and wondered what I could do with them - and eventually stunbled upon a PM Model Fokker D.XXI. Why not retrograde this early monoplane fighter into a biplane, with relatively modern features?
Said and done, and the respective conversion/kitbashing was a rather straightforward affair, even though not without some challenges.
The biggest issue became the lower wings: the Gladiator wings are much thinner and have less depth than the original Fokker wings, so that much of the wing roots on the fuselage had to be sanded away. This resulted in gaping openings, which had to be filled, including a resculpted trailing edge intersection. Not a complicated feat, but messy.
Another issue arose through the fact that the D.XXI's fuselage is wider than the Gloster Gladiator's - resulting in a wider span of the lower wings than the upper! In order to correct this, the lower wings' tips were clipped and I used the occasion to re-sculpt all wing tips, trying to get away from the Gladiator's characteristic round shape.
Once the lower wings were mated with the fuselage, the upper wings were added with the help of the outer support struts only. Once dry, the additional struts between the upper wing and the fuselage were added - the latter were scratched with styrene strips. Thin styrene was also used to add some diagonal bracing struts, once more in an attempt to change the wings' look away from its Gladiator origins.
The spatted wheels were taken from the PM Model kit, but shortened by 2mm - OOB they are IMHO much too long, and the result would be a very stalky stance. The tail wheel was also taken OOB, but moved aft and shortened, too.
Inside, a different seat was used; a box was placed behind it, filling the gap, and a dashboard was added under the windshield. The canopy (very thick material!) was cut into three pieces, for a potential open presentation.
Engine and cowling were taken OOB, but the propeller was replaced with a better-looking scrap box find, which also received a longer axis for better balance and free spinning.
The rigging was done with material derived from heated, black IP sprues, which I like because it bonds well with the kit's plastic and can be attached with standard glue. Additionally, the wire's strength can the individually tailored.
Painting and markings:
I used this occasion to apply the somewhat obscure camouflage of the Royal Danish Air Force from the late Thirties. While the scheme itself is rather simple, the colors remain obscure. In profiles and painting instructions you can find a wide range of recommendations - ranging from sand or a greenish yellow and olive drab to dark green and dark earth! The undersides were supposed to be "bluish grey".
I eventually settled upon a relatively simple choice, with Humbrol 83 (Ochre) and Revell 46 (NATO Olive Drab, RAL 7013 a.k.a. Gelboliv), which looks almost like a dark brown together with the greenish sand tone. IMHO they make a good combo for the Danish scheme. For the undersides, I went for Humbrol 128 (FS 36320). Interior surfaces were painted in a dark slate grey tone, the propeller received an aluminum front and flat black back surfaces.
The kit received a light black ink wash and a post-shading treatment with various shades of the basic tones, including ModelMaster RAL 7028 (German WWII Dunkelgelb) as well as Humbrol 155, 163 and 247. Finally, the fabric structure on the wings was slightly emphasized with dry-brushed light grey, and exhaust soot under the fuselage was added with grinded graphite.
The markings come from various sources: roundels from a D.XXI sheet from PrintScale, the flags on the fin belong to a Danish F-100 (XtraDecal) and the tactical code was puzzled together. The nose art, the charging knight on the cowling, which I added because I found the overall aircraft to look pretty bleak, comes from a ModelCollect tank model sheet.
Finally, the whole kit was sealed with matt acrylic varnish (Italeri).
Not a spectacular whif, and this one does not really stand out between similar builds (e.g. the Macchi Brezza or the Gloster Glaive) I did before, but I find it interesting how good and plausible the retrograded Fokker D.XXI looks. The new/old wings blend in nicely, and the Danish scheme looks good on this biplane, too, even though I wonder why these colors were chosen? It looks rather like a desert paint scheme than something for Northern Europe, with lots of water and mostly green, flat landscape?

Some background:
The Skorpion was the result of the dire need for powerfully armed medium tanks when it was clear in 1944 that the German army would be faced with increasing numbers of Allied tanks. The favored solution would have been an update of the Panzer IV with the powerful 7.5 cm KwK 42 L/70 cannon, but the hull could not carry a turret that was gig enough to house this weapon - it should take several years until an satisfatory update would appear with the Panzer IV K. The alternative were self-propelled weapon carriers and the turret-less Jagdpanzer IV, which could take the long L70 gun, but both were not the tanks the Wehrmacht was looking for.
As a stopgap measure and to fill the ranks of the new Panzer V Panther, Krupp proposed a radically different layout: mounting the KwK 42 cannon with the Panther turret on the chassis of the Geschützwagen III/IV, which took elements of both the Panzer III (driving and steering system) and Panzer IV chassis (suspension and engine). This chassis ahd originally been developed for self-propelled artillery project, with the engine moved from the back of the hull to a front position next to the driver, so that the rear offered space for a combat section. The same chassis was already used for the Nashorn tank destroyer (with an 8,8cm PaK) and the Hummel mobile artillery support (with a 15cm howitzer) for the tank force. Both had an open-topped superstructure, built up around the respective large guns to give the crew some protection, and armor was relatively light, too, as these verhicles were not intended for direct confrontation with tanks.
However, the Panzer III/IV chassis was proven and already in production, and the Panther turret was available, too. For the SdKfz. 168 the open compartment of the Nashorn and Hummel was replaced by a closed, armored deck, which was large enough to carry a ring bearing for the Panther turret and it's drive. Overall armor, esp. on the new tank's front, was beefed up with extra plating, reaching up to 90mm. The crew was reduced to four, since the engine now took the position of the former Panzer IV radio/MG operator next to the driver.
In order to improve the tanks agility and speed, a torsion bar suspension and larger, double-interleaved rubber-rimmed steel roadwheels was proposed, but production started with the spring leaf suspension from the Panzer IV.
The rear turret's rear position had already been proposed for some heavy tank designs (e.g. by Porsche for the Tiger I proposals, which eventually evolved into the Ferdinand/Elefant tank hunter) but had never been employed before. Due to the unusual layout of the tank, the SdKfz. 168 was quickly dubbed "Skorpion".
One of the benefits were a more even weight distribution and a more compact size of the tank, since the long gun barrel did not protrude much over the hull's front end. Another indirect benefit was additional protection for the turret crew through the engine. Loading of ammuntion was also made easier through a rear hatch in the turret as well as in the lower hull that allowed direct access to the shell bunkers under the turret.
Drawbacks were an impaired field of view for the commander, esp. when the vehicle was hidden behind corners, and the field of fire was also limited in such ambush situations. The high silhouette was a tactical weakness, too, but this was regarded as acceptable, as this was a little price to pay for being able to carry the KwK 42/L70.
The Rheinmetall-Borsig 7.5 cm KwK 42 (L/70) featured semi-automatic shell ejection and a supply of 72 rounds). It used three different types of ammunition: APCBC-HE (Pzgr. 39/42), HE (Sprgr. 42) and APCR (Pzgr. 40/42), the last of which was usually in short supply.
While it was of a calibre common on Allied tanks, the Panther's gun was one of the most powerful of World War II, due to the large propellant charge and the long barrel, which gave it a very high muzzle velocity and excellent armour-piercing qualities. This 75 mm gun had actually more penetrating power than the main gun of the Tiger I heavy tank, the 8.8 cm KwK 36 L/56, although the larger 88 mm projectile might inflict more damage if it did penetrate.
Additionally, a MG 34 machine gun was located co-axially with the main gun on the gun mantlet, and another MG 34 was carried on board for close range and anti-aircraf defense.
A status report on 15 December 1944 already listed 41 Skorpion tanks assigned to the Western Front, with 36 operational (87 percent). This was one day before the start of the Battle of the Bulge. The Skorpion demonstrated its prowess in open country, where it could hit its targets at long range with near-impunity, but it also showed its vulnerability in the close-in fighting of the small towns of the Ardennes, where they suffered heavy losses. A status report on 15 January 1945 showed only 17 operational SdKfz. 168 left in the units involved in the operation, out of 82 still in their possession at that time.
In February 1945, all Skorpion tanks were transferred from the West to the Eastern Front, where they filled gaps in the ranks of the Panther battalions. None of the roundabout 180 built and converted SdKfz. 168 survived the hostitilities.

The kit and its assembly:
The "Skorpion" was partly inspired by thoughts about alternative tank designs like the Merkava, and also by available donation parts in the kit pile, where I found a leftover Panther Ausf. D, earmarked for another conversion, esp. with a new turret.
The Panther turret is big (like the whole tank itself), and the problem to mount more powerful cannons on the Panzer IV chassis could have led to some unusual, if not improvised designs.
The Panzer III/IV chassis for self-propelled artillery was the perfect basis, so I dedided to combine both for an alternative late WWII tank, conceptionally between a classic battle tank and a self-propelled gun carrier. The Panther turret just fits on the wide back section of the Hummel, even though proportions looks odd and the armor with many vertical surfaces is not very good. But, after all, this is intended to be a second choice concept and not a clean sheet battle tank design.
The chassis comes from an ESCI "Hummel", while the Panther turret is from a Hasegawa kit. The Hummel was more or less built OOB, just the open rear section was "clipped" at driver roof level and faired over with styrene sheet. Then, an opening for the Panther turret was cut out, and finally, once the rotation radius was clear, some more details added.
Another deviation from the OOB kit is the vinyl track. This ESCI kit came with styrene segment tracks, and IIRC it originally came with a silver, very stiff vinyl track when I built the Hummel for the first time many years ago - not a pleasant experience. Anyway, I decided to go the the Pavla replacement vinyl tracks, because they are very delicate and soft, moulded in a matt dark grey rubber.
Painting and markings:
This one looks rather wild - and it's a design experiment. The camouflage is a typical Hinterhalt (Ambush) paint scheme in Dark Yellow, Olive Green and Red Brown, onto which spots in light gray and dark brown have been added, for an even more disruptive effect in urban environment - slightly inspired by the unique British Forces Berlin scheme.
Basic tones are Humbrol 63, 160 and 117, plus extra spots with Humbrol 28 and 173. Then the model was weathered with a light black ink wash and dry-brushing with mid-stone and light gray, some acrylic paint to simulate dust and rust, and finally some dry pigments around the suspension and on the hull that simulate mud.
Markings are minimal, just some German crosses on the hull and the tactical code in red on a dedicated beige background - otherwise, it would not have been recognizable at all on the disruptive scheme!
The tracks, made from black, soft vinyl, received a paint treatment in order to get rid of that shiny vinyl look: at first, with a mix of black, sienna and silver, which was immediately wiped off again, and later with a second, similar turn with silver and dark brown.
An odd concept, and the result looks rather weird - be it the tank concept and the parts used in it, but also the totally fragmented paint scheme which looks gaudy and almost clown-esques, but succesfully breaks up the lines of the boxy vehicle. So, why not?

Some background:
Alexander Martin Lippisch (November 2, 1894 – February 11, 1976) was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of flying wings, delta wings and the ground effect.
After working intially for the Zeppelin company, Reichsluftfahrtsministerium (RLM, Reich Aviation Ministry) transferred Lippisch and his team in 1939 to work at the Messerschmitt factory, in order to design a high-speed fighter aircraft around the rocket engines then under development by Hellmuth Walter. The team quickly adapted their most recent design, the DFS 194, to rocket power, the first example successfully flying in early 1940. This successfully demonstrated the technology for what would become the Messerschmitt Me 163 Komet, his most famous design.
In 1943, Lippisch transferred to Vienna’s Aeronautical Research Institute (Luftfahrtforschungsanstalt Wien, LFW), to concentrate on the problems of high-speed flight.That same year, he was awarded a doctoral degree in engineering by the University of Heidelberg. However, his research work did not stop Lippisch from designing further, mostly jet-powered and tailless fighter aircraft, e. g. for Henschel.
In early 1944, the RLM became aware of Allied jet developments and the high altitude B-29 in the Pacific TO, which was expected to appear soon over Europe, too. In response, the RLM instituted the Emergency Fighter Program, which took effect on July 3, 1944, ending production of most bomber and multi-role aircraft in favour of fighters, especially jet fighters. Additionally, they accelerated the development of experimental designs that would guarantee a performance edge over the Allied opponents, and designs that would replace the first generation of the German jet fighters, namely the Messerschmitt Me 262 and Heinkel He 162.
One of these advanced designs was the Ta 183 fighter, built by Focke Wulf and developed by Kurt Tank. The Ta 183 had a short fuselage with the air intake passing under the cockpit and proceeding to the rear where the single engine was located. The wings were swept back at 40° and were mounted in the mid-fuselage position. The pilot sat in a pressurized cockpit with a bubble canopy, which provided excellent vision. The primary armament of the aircraft consisted of four 30 mm (1.18 in) MK 108 cannons arranged around the air intake. The Ta 183 had a planned speed of about 1,000 km/h (620 mph) at 7,000 m (22,970 ft) and was powered by a 2nd generation jet engine, the Heinkel HeS 011 turbojet with 13 kN (2,700 lbf) of thrust. Several, steadily improved variants of the Ta 183 entered service from mid 1945 onwards, and the type was also the basis for more thorough derivatives - including a high altitude jet fighter proposed by Alexander Lippisch.
The resulting aircraft mated the structural basis of the proven Ta 183 with advanced aerodynamics, namely a tailless design with a much increased wing and fin area, and the machine was also powered by the new BMW 018 jet engine which delivered at this early stage 25kN (5.200 lb) of thrust and was expected to achieve more than 36 kN (7.500 lb) soon, without bigger dimensions than the widely used HeS 011 at the time.
The resulting machine, designated Li 383 in order to honor the developer, sacrificed some of the Ta 183' agility and speed for sheer altitude and climb performance, and the new wings were mostly built from non-strategic material, what increased weight considerably - the Li 383 was 1.5 times as heavy as the nimble Ta 183 fighter, but the new wing was more than twice as large.
Nevertheless, the modifications were effective and the RLM quickly accepted the radical re-design, since no better options were available on short notice. While the Ta 183 fighter was able to reach 14.000m (45,935 ft) in a zoom climb, the Li 383 could easily operate at 16.000m (52.500 ft) and even above that. However, Alexander Lippisch's original design, the Li 383A, had, despite positive wind tunnel tests, turned out to be unstable and prone to spinning. The reason was quickly found to be a lack of latitudal surfaces, and this was quickly fixed with a bigger tail fin and a characteristic gull wing that gave it the inofficial nickname for the serial Li 383B, "Sturmvogel".
When the Allied Forces eventually added the high-flying B-29 bombers to their air raids over Germany in late 1945, the Li 383 B-1 serial production variant was just ready for service. The new machines were quickly delivered to front line units, primarily fighter squadrons that defended vital centers like Berlin, Munich or the Ruhrgebiet. However, even though the Li 383 B-1's performance was sufficient, the type suffered from an inherent weakness against the well-armed Allied bombers: the range of the MK 108 cannon. While this weapon was relatively light and compact, and the four guns delivered an impressive weight of fire, a close attack against massive bomber formations was highly hazardous for the pilots. As a consequence, since bigger guns could not be mounted in the compact Ta 183 airframe, several weapon sets for filed modifications (so-called Rüstsätze) were offered that added a variety of weapons with a longer range and a bigger punch to the Li 383 B-1's arsenal, including unguided and guided air-to-air missiles.
Anyway, the Li 383's overall impact was not significant. Production numbers remained low, and all in all, only a total of 80-100 machines were completed and made operational when the hostilities ended.

The kit and its assembly:
This fictional Luft ’46 aircraft was inspired by the question what a further developed Ta 183 could have looked like, and it was also influenced by the many tailless Lippisch designs that never left the drawing board.
From the hardware perspective, the design is more or less the salvage of the most useable parts of the PM Model Horten IX/Go 229 kit – namely the outer wing sections. The PM Model Ta 183 is only marginally “better”, and I had one of these in the stash (Revell re-boxing), too. So, why not combine two dreadful kits into something …new?
Well, that was the plan, and building was rather straightforward. In the cockpit, I added simple side consoles, a dashboard, some oxygen flasks, a different seat and a pilot figure (seatbelts simulated with tape strips) – the kit would be finished with closed canopy.
An exhaust pipe was integrated and the air intake filled with a better compressor fan (from an Airfix D.H. Venom, IIRC, fits perfectly). The inner walls of the landing gear wells (well, they are not existent) were cut away and replaced with leftover jet engine parts, so that there was some structure and depth. The landing gear was taken OOB, though, I just used slightly bigger wheels, since the “new” aircraft would have considerably more mass than the Ta 183.
The highly swept, long Ta 183 tail was cut off and replaced by a surplus Me 262 fin and tail section (Matchbox). Despite the different shape and size, and the resulting side view profile reminds strangely of the Saab 29?
The original Ta 183 wings were not mounted and their attachment points on the fuselage cut/sanded away. Instead, I used the outer wing sections from the Go 229, with clipped wing tips for a different shape.
When I held the wings to the fuselage, the whole thing looked …boring. Something was missing, hard to pinpoint. After consulting some Luft ’46 literature I adapted a trick for better stability: a gull wing shape. This was achieved through simple cuts to the wings’ upper halves. Then the wings were bent down, the gap filled with a styrene strip, and finally PSRed away. Looks very dynamic, and also much better!
Another late addition was the underwing armament. I was about to start painting when I again found that something was missing… The new wings made the aircraft pretty large, so I considered some underwing ordnance. Anyway, I did not want to disrupt the relatively clean lines with ugly bombs or drop tanks, so I installed a pair of racks with six launch tubes for R 65 “Föhn” unguided AAMs into the lower wing surfaces, in a semi-recessed position and with a deflector plate for the rocket exhausts.
Painting and markings:
As a high altitude interceptor and late war design, this one was to receive a simple and relatively light livery, even though I stuck with classic RLM tones. The Li 383 was basically painted all-over RLM 76 (Humbrol 247), onto which RLM 75 (from Modelmaster) was added, in the form of highly thinned enamel paint for a cloudy and improvised effect, applied with a big and soft brush. On top of the wings, a typical two-tone scheme was created, while on the fuselage’s upper sides only some thin mottles were added.
In order to lighten the scheme up and add a unique twist, I added further mottles to the flanks and the fin, but this time with RLM 77. This is a very light grey – originally reserved for tactical markings, but also “abused” in the field for camouflage mods, e. g. on high-flying He 177 bombers. I used Humbrol 195 (RAL 7035), again applied with a brush and highly thinned for a rather cloudy finish.
The air intake section and the intake duct were painted in aluminum, while the engine exhaust section as well as the missile racks and the areas around the gun ports were painted with Revell 99 (Iron Metallic) and Steel Metallizer.
The cockpit interior became dark grey (RLM 66) while the landing gear, the wells and the visible engine parts inside became RLM 02.
The kit was lightly weathered with a thin black ink wash and some dry-brushing.
The markings were puzzled together; due to the light basic tones of the model, the upper crosses became black, with only a very small cross on the flanks due to the lack of space, and for the wings’ undersides I used “old school” full color markings in black and white. The red color for the tactical code was basically chosen because it would be a nice contrast to the bluish-grey overall livery.
Finally the kit was sealed with matt acrylic varnish and some gun soot stains added with grinded graphite, as well as some traces of flaked paint on the wings’ leading edges and around the cockpit.
Well, the attempt to bash two mediocre (at best) kits into something else and hopefully better worked out well – the Li 383 does not look totally out of place, even though it turned out to become a bigger aircraft than expected. However, the aircraft has this certain, futuristic Luft ’46 look – probably thanks to the gull wings, which really change the overall impression from a simple kitbash to a coherent design which-could-have-been. The livery also fits well and looks better than expected. Overall, a positive surprise.

Some background:
After World War I, the German aircraft industry had several problems. German airlines were forbidden to operate multi engine aircraft and during a period all manufacturing of aircraft in Germany was banned. By 1921, some of the restrictions was lifted, civilian aircraft could be made after approval of an international control commission if they fulfilled certain requirements. To bypass these rules and to be able to make whatever aircraft they wanted several aircraft manufacturers moved abroad. In 1921, Carl Bücker handled the purchase of a reconnaissance aircraft from Caspar-Werke in Travemünde. Because they expected problems due to the rules in the peace treaty regarding the export of German fighter aircraft, Bücker explored the possibility to smuggle the parts out of Germany and assemble the aircraft in Sweden.
To make the purchase easier, Ernst Heinkel and Bücker started Svenska Aero in Lidingö in 1921. The contract on the aircraft was transferred from Caspar to Svenska Aero. Heinkel and some German assembly workers temporarily moved to Lidingö to assemble the aircraft. During 1922 to 1923, the company moved into a former shipyard in Skärsätra on Lidingö since the company had received additional orders from the navy's air force. The parts for those aircraft were made in Sweden by Svenska Aero but assembled by TDS. In 1928, the navy ordered four J 4 (Heinkel HD 19) as a fighter with pontoons. That delivery came to be the last licens- built aircraft by Svenska Aero. In the mid-1920s, Svenska Aero created their own design department to be able to make their own aircraft models. Sven Blomberg, earlier employed by Heinkel Flugzeugwerke, was hired as head of design. In 1930, he was joined by Anders Johan Andersson from Messerschmitt. Despite that, Svenska Aero designed and made several different models on their own.
One of them was the model SA-16, a direct response to the Swedish Air Force and Navy’s interest in the new dive bomber tactics, which had become popular in Germany since the mid-Thirties and had spawned several specialized aircraft, the Junkers Ju 87 being the best-known type. The Flygvapnet (Swedish Air Force) had already conducted dive bombing trials with Hawker Hart (B 4) biplanes, but only with mixed results. Diving towards the target simplified the bomb's trajectory and allowed the pilot to keep visual contact throughout the bomb run. This allowed attacks on point targets and ships, which were difficult to attack with conventional level bombers, even en masse. While accuracy was increased through bombing runs at almost vertical dive, the aircraft were not suited for this kind of operations – structurally, and through the way the bombs were dropped.
Therefore, Svenska Aero was tasked to develop an indigenous dedicated dive bomber, primarily intended to attack ships, and with a secondary role as reconnaissance aircraft – a mission profile quite similar to American ship-based “SB” aircraft of the time. Having learnt from the tests with the Hawker Harts, the SA-16 was a very robust monoplane, resulting in an almost archaic look. It was a single-engine all-metal cantilever monoplane with a fixed undercarriage and carried a two-person crew. The main construction material was duralumin, and the external coverings were made of duralumin sheeting, bolts and parts that were required to take heavy stress were made of steel. The wings were of so-called “double-wing” construction, which gave the SA-16 considerable advantage on take-off; even at a shallow angle, large lift forces were created through the airfoil, reducing take-off and landing runs. Retractable perforated air brakes were mounted under the wings’ leading edges. The fully closed “greenhouse cabin” offered space for a crew of two in tandem, with the pilot in front and a navigator/radio operator/observer/gunner behind. To provide the rear-facing machine gun with an increased field of fire, the stabilizers were of limited span but deeper to compensate for the loss of surface, what resulted in unusual proportions. As a side benefit, the short stabilizers had, compared with a wider standard layout, increased structural integrity. Power came from an air-cooled Bristol Mercury XII nine-cylinder radial engine with 880 hp (660 kW), built by Nohab in Sweden.
Internal armament consisted of two fixed forward-firing 8 mm (0.315 in) Flygplanskulspruta Ksp m/22F (M1919 Browning AN/M2) machine guns in the wings outside of the propeller disc. A third machine gun of the same type was available in the rear cockpit on a flexible mount as defensive weapon. A total of 700 kg (1,500 lb) of bombs could be carried externally. On the fuselage centerline, a swing arm could hold bombs of up to 500 kg (1.100 lb) caliber and deploy them outside of the propeller arc when released in a, additional racks under the outer wings could hold bombs of up to 250 kg (550 lb) caliber each or clusters of smaller bombs, e. g. four 50 (110 lb) or six 12 kg (26 ½ lb) bombs.
Flight testing of the first SA-16 prototype began on 14 August 1936. The aircraft could take off in 250 m (820 ft) and climb to 1,875 m (6,152 ft) in eight minutes with a 250 kg (550 lb) bomb load, and its cruising speed was 250 km/h (160 mph). This was less than expected, and pilots also complained that navigation and powerplant instruments were cluttered and not easy to read, especially in combat. To withstand strong forces during a dive, heavy plating, along with brackets riveted to the frame and longeron, was added to the fuselage. Despite this, pilots praised the aircraft's handling qualities and strong airframe. These problems were quickly resolved, but subsequent testing and progress still fell short of the designers’ hopes. With some refinements the machine's speed was increased to 274 km/h (170 mph) at ground level and 319 km/h 319 km/h (198 mph, 172 kn) at 3,650 m (11,980 ft), while maintaining its good handling ability.
Since the Swedish Air Force was in dire need for a dive bomber, the SA-16 was accepted into service as the B 9 – even though it was clear that it was only a stopgap solution on the way to a more capable light bomber with dive attack capabilities. This eventually became the Saab 17, which was initiated in 1938 as a request from the Flygvapnet to replace its fleet of dive bombers of American origin, the B 5 (Northrop A-17), the B 6 (Seversky A8V1) and the obsolete Fokker S 6 (C.Ve) sesquiplane, after the deal with Fokker to procure the two-engine twin-boom G.I as a standardized type failed due to the German invasion of the Netherlands. The B 9 dive bomber would subsequently be replaced by the more modern and capable B 17 in the long run, too, which made its first flight on 18 May 1940 and was introduced to frontline units in March 1942. Until then, 93 SA-16s had been produced between 1937 and 1939. When the B 17 became available, the slow B 9 was quickly retired from the attack role. Plans to upgrade the aircraft with a stronger 14 cylinder engine (a Piaggio P.XIbis R.C.40D with 790 kW/1,060 hp) were not carried out, as it was felt that the design lacked further development potential in an offensive role.
Because the airframes were still young and had a lot of service life ahead of them, most SA-16s were from 1941 on relegated to patrol and reconnaissance missions along the Swedish coastlines, observing ship and aircraft traffic in the Baltic Sea and undertaking rescue missions with droppable life rafts. For long-range missions, the forked ventral swing arm was replaced with a fixed plumbed pylon for an external 682 liters (150 Imp. gal.) auxiliary tank that more than doubled the aircraft’s internal fuel capacity of 582 liters, giving it an endurance of around 8 hours. In many cases, the machine guns on these aircraft were removed to save weight. In this configuration the SA-16 was re-designated S 9 (“S” for Spaning) and the machines served in their naval observation and SAR role well into the Fifties, when the last SA-16s were retired.

The kit and its assembly:
This purely fictional Swedish dive bomber was inspired by reading about Flygvapnet‘s pre-WWII trials with dive bombing tactics and the unsuited aircraft fleet for this task. When I found a Hasegawa SOC Seagull floatplane in The Stash™ and looks at the aircraft’s profile, I thought that it could be converted into a two-seat monoplane – what would require massive changes, though.
However, I liked the SOC’s boxy and rustic look, esp. the fuselage, and from this starting point other ingredients/donors were integrated. Work started with the tail. Originally, I wanted to retain the SOCs fin and stabilizer, but eventually found them oversized for a land-based airplane. In the scrap box I found a leftover fin from an Academy P-47, and it turned out to be a very good, smaller alternative, with the benefit that it visually lengthened the rear fuselage. The stabilizers were replaced with leftover parts from a NOVO Supermarine Attacker – an unlikely choice, but their size was good, they blended well into the overall lines of the aircraft, and they helped to stabilize the fin donor. Blending these new parts into to SOC’s hull required massive PSR, though.
The wings were also not an easy choice, and initially I planned the aircraft with a retractable landing gear. I eventually settled on the outer wings (just outside of the gullwing kink) from an MPM Ju 87 B, because of their shape and the archaic “double wings” that would complement the SOC’s rustic fuselage. However, at this point I refrained from the retractable landing gear and instead went for a fixed spatted alternative, left over from an Airfix Hs 123, which would round up the aircraft’s somewhat vintage look. Because the wheels were missing, I inserted two Matchbox MiG-21 wheels (which were left over in the spares bin from two different kits, though). The tail wheel came from an Academy Fw 190.
Cowling and engine inside (thankfully a 9-cylinder radial that could pose as a Mercury) were taken OOB, just the original two-blade propeller was replaced with a more appropriate three-blade alternative, IIRC from a Hobby Boss Grumman F4F. The cockpit was taken OOB, and I also used the two pilot figures from the kit. The rear crew member just had the head re-positioned to look sideways, and had to have the legs chopped off because there’s hardly and space under the desk with the radio set he’s sitting at.
The ventral 500 kg bomb came from a Matchbox Ju 87, the bomb arms are Fw 189 landing gear parts. Additional underwing pylons came from an Intech P-51, outfitted with 50 kg bombs of uncertain origin (they look as if coming from an old Hasegawa kit). The protruding machine gun barrel fairings on the wings were scratched from styrene rod material, with small holes drilled into them.
A real Frankenstein creation, but it does not look bad or implausible!
Painting and markings:
I gave the B 9 a camouflage that was carried by some Flygvapnet aircraft in the late Thirties, primarily by fighters imported from the United States but also some bombers like the B 3 (Ju 86). The IMHO quite attractive scheme consists on the upper surfaces of greenish-yellow zinc chromate primer (Humbrol 81, FS 33481), on top of which a dense net of fine dark green wriggles (supposed to be FS 34079, but I rather used Humbrol 163, RAF Dark Green, because it is more subdued) was manually applied with a thin brush, so that the primer would still shine through, resulting in a mottled camouflage.
On the real aircraft, this was sealed with a protective clear lacquer to which 5% of the dark green had been added, and I copied this procedure on the model, too, using semi-gloss acrylic varnish with a bit of Revell 46 added. The camouflage was wrapped around the wings’ leading edges and the spatted landing gear was painted with the upper camouflage, too.
The undersides were painted with Humbrol 87 (Steel Grey), to come close to the original blue-grey tone, which is supposed to be FS 35190 on this type of camouflage. The tone is quite dark, almost like RAF PRU Blue.
The interior was painted – using a Saab J 21 cockpit as benchmark – in a dark greenish grey (RAL 7009).
The model received the usual light black ink washing and some post-panel shading on the lower surfaces, because this effect would hardly be recognizable on the highly fragmented upper surface.
The markings are reflecting Flygvapnet’s m/37 regulations, from the direct pre-WWII era when the roundels had turned from black on white to yellow on blue but still lacked the yellow edge around the roundel for more contrast. F6 Västgöta flygflottilj was chosen because it was a dive bomber unit in the late Thirties, and the individual aircraft code (consisting of large white two-digit numbers) was added with the fin and the front of the fuselage. “27” would indicate an aircraft of the unit’s 2nd division, which normally had blue as a standardized color code, incorporated through the blue bands on the spats and the small "2nd div." tag on the rudder (from a contemporary F8 Swedish Gladiator).
Roundels and codes came from an SBS Models sheet, even though they belong to various aircraft types. Everything was finally sealed with matt acrylic varnish.

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

The A-14 program originally started in 2005 as a private venture, initiated by Northrop-Grumman together with the Elbit Group as a joint venture through Elbit’s Texas-based aircraft division M7 Aerosystems, an approved supplier to major aerospace clients. The aircraft was intended to replace the USAF’s A-10 attack aircraft as well as early F-16s in the strike role from 2010 onwards. The time slot for the project turned out to be advantageous, because at that time the USAF was contemplating to replace the simple and sturdy A-10 with the much more complex F-35, eventually even with its VTOL variant, and the highly specialized F-117 was retired, too.
The A-14 revived conceptual elements of Grumman’s stillborn A-12 stealth program for the US Navy, which had also been part of the USAF’s plans to replace the supersonic F-111 tactical bomber, but on a less ambitious and expensive level concerning technology, aiming for a more effective compromise between complexity, survivability and costs. The basic idea was an updated LTV A-7D (the A-10’s predecessor from the Vietnam War era), which had far more sophisticated sensor and navigation equipment than the rather simple but sturdy A-10, but with pragmatic stealth features and a high level of survivability in a modern frontline theatre or operations.
M7 Aerosystems started on a blank sheet, even though Northrop-Grumman’s A-12 influence was clearly visible, and to a certain degree the aircraft shared the basic layout with the F-117A. The A-14 was tailored from the start to the ground attack role, and therefore a subsonic design. Measures to reduce radar cross-section included airframe shaping such as alignment of edges, fixed-geometry serpentine inlets that prevented line-of-sight of the engine faces from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and maintenance covers that could provide a radar return. The A-14 was furthermore designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye.
The resulting airframe was surprisingly large for an attack aircraft – in fact, it rather reminded of a tactical bomber in the F-111/Su-24 class than an alternative to the A-10. The A-14 consisted of a rhomboid-shaped BWB (blended-wing-and-body) with extended wing tips and only a moderate (35°) wing sweep, cambered leading edges, a jagged trailing edge and a protruding cockpit section which extended forward of the main body.
The majority of the A-14’s structure and surface were made out of a carbon-graphite composite material that is stronger than steel, lighter than aluminum, and absorbs a significant amount of radar energy. The central fuselage bulge ended in a short tail stinger with a pair of swept, canted fins as a butterfly tail, which also shrouded the engine’s hot efflux. The fins could have been omitted, thanks to the aerodynamically unstable aircraft’s fly-by-wire steering system, and they effectively increased the A-14’s radar signature as well as its visual profile, but the gain in safety in case of FBW failure or physical damage was regarded as a worthwhile trade-off. Due to its distinctive shape and profile, the A-14 quickly received the unofficial nickname “Squatina”, after the angel shark family.
The spacious and armored cockpit offered room for the crew of two (pilot and WSO or observer for FAC duties), seated side-by-side under a generous glazing, with a very good field of view forward and to the sides. The fuselage structure was constructed around a powerful cannon, the five-barrel GAU-12/U 25 mm ‘Equalizer’ gun, which was, compared with the A-10’s large GAU-8/A, overall much lighter and more compact, but with only little less firepower. It fired a new NATO series of 25 mm ammunition at up to 4.200 RPM. The gun itself was located under the cockpit tub, slightly set off to port side, and the front wheel well was offset to starboard to compensate, similar in arrangement to the A-10 or Su-25. The gun’s ammunition drum and a closed feeding belt system were located behind the cockpit in the aircraft’s center of gravity. An in-flight refueling receptor (for the USAF’s boom system) was located in the aircraft’s spine behind the cockpit, normally hidden under a flush cover.
Due to the gun installation in the fuselage, however, no single large weapon bay to minimize radar cross section and drag through external ordnance was incorporated, since this feature would have increased airframe size and overall weight. Instead, the A-14 received four, fully enclosed compartments between the wide main landing gear wells and legs. The bays could hold single iron bombs of up to 2.000 lb caliber each, up to four 500 lb bombs or CBUs, single laser-guided GBU-14 glide bombs, AGM-154 JSOW or GBU-31/38 JDAM glide bombs, AGM-65 Maverick guided missiles or B61 Mod 11 tactical nuclear weapons, as well as the B61 Mod 12 standoff variant, under development at that time). Retractable launch racks for defensive AIM-9 Sidewinder air-to-air missiles were available, too, and additional external pylons could be added, e.g. for oversize ordnance like AGM-158C Long Range Anti-Ship Missile (LRASM) or AGM-158 Joint Air to Surface Standoff Missile (JASSM), or drop tanks for ferry flights. The total in- and external ordnance load was 15,000 lb (6,800 kg).
The A-14 was designed with superior maneuverability at low speeds and altitude in mind and therefore featured a large wing area, with high wing aspect ratio on the outer wing sections, and large ailerons areas. The ailerons were placed at the far ends of the wings for greater rolling moment and were split, making them decelerons, so that they could also be used as air brakes in flight and upon landing.
This wing configuration promoted short takeoffs and landings, permitting operations from primitive forward airfields near front lines. The sturdy landing gear with low-pressure tires supported these tactics, and a retractable arrester hook, hidden by a flush cover under the tail sting, made it possible to use mobile arrested-recovery systems.
The leading edge of the wing had a honeycomb structure panel construction, providing strength with minimal weight; similar panels covered the flap shrouds, elevators, rudders and sections of the fins. The skin panels were integral with the stringers and were fabricated using computer-controlled machining, reducing production time and cost, and this construction made the panels more resistant to damage. The skin was not load-bearing, so damaged skin sections could be easily replaced in the field, with makeshift materials if necessary.
Power came from a pair of F412-GE-114 non-afterburning turbofans, engines that were originally developed for the A-12, but de-navalized and lightened for the A-14. These new engines had an output of 12,000 lbf (53 kN) each and were buried in blended fairings above the wing roots, with jagged intakes and hidden ducts. Flat exhausts on the wings’ upper surface minimized both radar and IR signatures.
Thanks to the generous internal fuel capacity in the wings and the fuselage, the A-14 was able to loiter and operate under 1,000 ft (300 m) ceilings for extended periods. It typically flew at a relatively low speed of 300 knots (350 mph; 560 km/h), which made it a better platform for the ground-attack role than fast fighter-bombers, which often have difficulty targeting small, slow-moving targets or executing more than just a single attack run on a selected target.
A mock-up was presented and tested in the wind tunnel and for radar cross-section in late 2008. The A-14’s exact radar cross-section (RCS) remained classified, but in 2009 M7 Aerosystems released information indicating it had an RCS (from certain angles) of −40 dBsm, equivalent to the radar reflection of a "steel marble". With this positive outcome and the effective design, M7 Aerosystems eventually received federal funding for the production of prototypes for an official DT&E (Demonstration Testing and Evaluation) program.
Three prototypes/pre-production aircraft were built in the course of 2010 and 2011, and the first YA-14 made its maiden flight on 10 May 2011. The DT&E started immediately, and the machines (a total of three flying prototypes were completed, plus two additional airframes for static tests) were gradually outfitted with mission avionics and other equipment. This included GPS positioning, an inertial navigation system, passive sensors to detect radar usage, a small, gyroscopically stabilized turret, mounted under the nose of the aircraft, containing a FLIR boresighted with a laser spot-tracker/designator, and an experimental 3-D laser scanning LIDAR in the nose as a radiation-less alternative to a navigation and tracking radar.
Soon after the DT&E program gained momentum in 2012, the situation changed for M7 Aerosystems when the US Air Force considered the F-35B STOVL variant as its favored replacement CAS aircraft, but concluded that the aircraft could not generate a sufficient number of sorties. However, the F-35 was established as the A-14’s primary rival and remained on the USAF’s agenda. For instance, at that time the USAF proposed disbanding five A-10 squadrons in its budget request to cut its fleet of 348 A-10s by 102 to lessen cuts to multi-mission aircraft in service that could replace the specialized attack aircraft.
In August 2013, Congress and the Air Force examined various proposals for an A-10 replacement, including the A-14, F-35 and the MQ-9 Reaper unmanned aerial vehicle, and, despite the A-14’s better qualities in the ground attack role, the F-35 came out as the overall winner, since it was the USAF’s favorite. Despite its complexity, the F-35 was – intended as a multi-role tri-service aircraft and also with the perspective of bigger international sales than the more specialized A-14 – regarded as the more versatile and, in the long run, more cost-efficient procurement option. This sealed the A-14’s fate and the F-35A entered service with U.S. Air Force F-35A in August 2016 (after the F-35B was introduced to the U.S. Marine Corps in July 2015). At that time, the U.S. planned to buy 2,456 F-35s through 2044, which would represent the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps for several decades.
Since the A-14’s technology was considered to be too critical to be marketed to export customers (Israel showed early interest in the aircraft, as well as South Korea), the program was cancelled in 2016.

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.
Painting and markings:
For a stealth aircraft and a prototype I wanted something subdued or murky, but not an all-black or -grey livery. I eventually settled for the rather dark paint scheme that the USAF applied to its late B-52Gs and the B-1Bs, which consists of two tones from above, FS 36081 (Dark Grey, a.k.a. Dark Gunship Grey) and 34086 (Green Drab), and underneath (FS 36081 and 36118 (Gunship Grey). The irregular pattern was adapted (in a rather liberal fashion) from the USAF’s early B-1Bs, using Humbrol 32, 108 and 125 as basic colors. The 108 turned out to be too bright, so I toned it down with an additional coat of thinned Humbrol 66. While this considerably reduced the contrast between the green and the grey, the combination looks much better and B-1B-esque.
The wings’ leading edges were painted for more contrast with a greyish black (Tar Black, Revell 09), while the landing gear, the interior of the air intakes and the open bomb bay became glossy white. The cockpit was painted in medium grey (Humbrol 140) and the clear parts received a thinned inner coating with a mix of transparent yellow and brown, simulating an anti-radar coating – even though the effect turned out to be minimal, now it looks as of the plastic parts had just yellowed from age…
After the initial livery had been finished the model received a black ink washing and some post-panel shading with slightly brightened variations of the basic tones (using Humbrol 79, 144 and 224). Decals were added next, an individual mix from various sources. The “Stars-and-Bars” come from a PrintScale A-7 sheet, most stencils come from an F-16 sheet.
After some more detail painting and a treatment with graphite on the metal areas (exhausts, gun port), the model was sealed with matt acrylic varnish (Italeri).
Batman’s next Batwing? Maybe, there’s certainly something fictional about this creation. But the “Squatina” turned out much more conclusive (and even pretty!) than I expected, even though it became a bigger aircraft than intended. And I am positively surprised how good the bodywork became – after all, lots of putty had to be used to fill all the gaps between parts that no one ever expected to be grafted together.
+++ 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:
After World War I, the German aircraft industry had several problems. German airlines were forbidden to operate multi engine aircraft and during a period all manufacturing of aircraft in Germany was banned. By 1921, some of the restrictions was lifted, civilian aircraft could be made after approval of an international control commission if they fulfilled certain requirements. To bypass these rules and to be able to make whatever aircraft they wanted several aircraft manufacturers moved abroad. In 1921, Carl Bücker handled the purchase of a reconnaissance aircraft from Caspar-Werke in Travemünde. Because they expected problems due to the rules in the peace treaty regarding the export of German fighter aircraft, Bücker explored the possibility to smuggle the parts out of Germany and assemble the aircraft in Sweden.
To make the purchase easier, Ernst Heinkel and Bücker started Svenska Aero in Lidingö in 1921. The contract on the aircraft was transferred from Caspar to Svenska Aero. Heinkel and some German assembly workers temporarily moved to Lidingö to assemble the aircraft. During 1922 to 1923, the company moved into a former shipyard in Skärsätra on Lidingö since the company had received additional orders from the navy's air force. The parts for those aircraft were made in Sweden by Svenska Aero but assembled by TDS. In 1928, the navy ordered four J 4 (Heinkel HD 19) as a fighter with pontoons. That delivery came to be the last licens- built aircraft by Svenska Aero. In the mid-1920s, Svenska Aero created their own design department to be able to make their own aircraft models. Sven Blomberg, earlier employed by Heinkel Flugzeugwerke, was hired as head of design. In 1930, he was joined by Anders Johan Andersson from Messerschmitt. Despite that, Svenska Aero designed and made several different models on their own.
One of them was the model SA-16, a direct response to the Swedish Air Force and Navy’s interest in the new dive bomber tactics, which had become popular in Germany since the mid-Thirties and had spawned several specialized aircraft, the Junkers Ju 87 being the best-known type. The Flygvapnet (Swedish Air Force) had already conducted dive bombing trials with Hawker Hart (B 4) biplanes, but only with mixed results. Diving towards the target simplified the bomb's trajectory and allowed the pilot to keep visual contact throughout the bomb run. This allowed attacks on point targets and ships, which were difficult to attack with conventional level bombers, even en masse. While accuracy was increased through bombing runs at almost vertical dive, the aircraft were not suited for this kind of operations – structurally, and through the way the bombs were dropped.
Therefore, Svenska Aero was tasked to develop an indigenous dedicated dive bomber, primarily intended to attack ships, and with a secondary role as reconnaissance aircraft – a mission profile quite similar to American ship-based “SB” aircraft of the time. Having learnt from the tests with the Hawker Harts, the SA-16 was a very robust monoplane, resulting in an almost archaic look. It was a single-engine all-metal cantilever monoplane with a fixed undercarriage and carried a two-person crew. The main construction material was duralumin, and the external coverings were made of duralumin sheeting, bolts and parts that were required to take heavy stress were made of steel. The wings were of so-called “double-wing” construction, which gave the SA-16 considerable advantage on take-off; even at a shallow angle, large lift forces were created through the airfoil, reducing take-off and landing runs. Retractable perforated air brakes were mounted under the wings’ leading edges. The fully closed “greenhouse cabin” offered space for a crew of two in tandem, with the pilot in front and a navigator/radio operator/observer/gunner behind. To provide the rear-facing machine gun with an increased field of fire, the stabilizers were of limited span but deeper to compensate for the loss of surface, what resulted in unusual proportions. As a side benefit, the short stabilizers had, compared with a wider standard layout, increased structural integrity. Power came from an air-cooled Bristol Mercury XII nine-cylinder radial engine with 880 hp (660 kW), built by Nohab in Sweden.
Internal armament consisted of two fixed forward-firing 8 mm (0.315 in) Flygplanskulspruta Ksp m/22F (M1919 Browning AN/M2) machine guns in the wings outside of the propeller disc. A third machine gun of the same type was available in the rear cockpit on a flexible mount as defensive weapon. A total of 700 kg (1,500 lb) of bombs could be carried externally. On the fuselage centerline, a swing arm could hold bombs of up to 500 kg (1.100 lb) caliber and deploy them outside of the propeller arc when released in a, additional racks under the outer wings could hold bombs of up to 250 kg (550 lb) caliber each or clusters of smaller bombs, e. g. four 50 (110 lb) or six 12 kg (26 ½ lb) bombs.
Flight testing of the first SA-16 prototype began on 14 August 1936. The aircraft could take off in 250 m (820 ft) and climb to 1,875 m (6,152 ft) in eight minutes with a 250 kg (550 lb) bomb load, and its cruising speed was 250 km/h (160 mph). This was less than expected, and pilots also complained that navigation and powerplant instruments were cluttered and not easy to read, especially in combat. To withstand strong forces during a dive, heavy plating, along with brackets riveted to the frame and longeron, was added to the fuselage. Despite this, pilots praised the aircraft's handling qualities and strong airframe. These problems were quickly resolved, but subsequent testing and progress still fell short of the designers’ hopes. With some refinements the machine's speed was increased to 274 km/h (170 mph) at ground level and 319 km/h 319 km/h (198 mph, 172 kn) at 3,650 m (11,980 ft), while maintaining its good handling ability.
Since the Swedish Air Force was in dire need for a dive bomber, the SA-16 was accepted into service as the B 9 – even though it was clear that it was only a stopgap solution on the way to a more capable light bomber with dive attack capabilities. This eventually became the Saab 17, which was initiated in 1938 as a request from the Flygvapnet to replace its fleet of dive bombers of American origin, the B 5 (Northrop A-17), the B 6 (Seversky A8V1) and the obsolete Fokker S 6 (C.Ve) sesquiplane, after the deal with Fokker to procure the two-engine twin-boom G.I as a standardized type failed due to the German invasion of the Netherlands. The B 9 dive bomber would subsequently be replaced by the more modern and capable B 17 in the long run, too, which made its first flight on 18 May 1940 and was introduced to frontline units in March 1942. Until then, 93 SA-16s had been produced between 1937 and 1939. When the B 17 became available, the slow B 9 was quickly retired from the attack role. Plans to upgrade the aircraft with a stronger 14 cylinder engine (a Piaggio P.XIbis R.C.40D with 790 kW/1,060 hp) were not carried out, as it was felt that the design lacked further development potential in an offensive role.
Because the airframes were still young and had a lot of service life ahead of them, most SA-16s were from 1941 on relegated to patrol and reconnaissance missions along the Swedish coastlines, observing ship and aircraft traffic in the Baltic Sea and undertaking rescue missions with droppable life rafts. For long-range missions, the forked ventral swing arm was replaced with a fixed plumbed pylon for an external 682 liters (150 Imp. gal.) auxiliary tank that more than doubled the aircraft’s internal fuel capacity of 582 liters, giving it an endurance of around 8 hours. In many cases, the machine guns on these aircraft were removed to save weight. In this configuration the SA-16 was re-designated S 9 (“S” for Spaning) and the machines served in their naval observation and SAR role well into the Fifties, when the last SA-16s were retired.

The kit and its assembly:
This purely fictional Swedish dive bomber was inspired by reading about Flygvapnet‘s pre-WWII trials with dive bombing tactics and the unsuited aircraft fleet for this task. When I found a Hasegawa SOC Seagull floatplane in The Stash™ and looks at the aircraft’s profile, I thought that it could be converted into a two-seat monoplane – what would require massive changes, though.
However, I liked the SOC’s boxy and rustic look, esp. the fuselage, and from this starting point other ingredients/donors were integrated. Work started with the tail. Originally, I wanted to retain the SOCs fin and stabilizer, but eventually found them oversized for a land-based airplane. In the scrap box I found a leftover fin from an Academy P-47, and it turned out to be a very good, smaller alternative, with the benefit that it visually lengthened the rear fuselage. The stabilizers were replaced with leftover parts from a NOVO Supermarine Attacker – an unlikely choice, but their size was good, they blended well into the overall lines of the aircraft, and they helped to stabilize the fin donor. Blending these new parts into to SOC’s hull required massive PSR, though.
The wings were also not an easy choice, and initially I planned the aircraft with a retractable landing gear. I eventually settled on the outer wings (just outside of the gullwing kink) from an MPM Ju 87 B, because of their shape and the archaic “double wings” that would complement the SOC’s rustic fuselage. However, at this point I refrained from the retractable landing gear and instead went for a fixed spatted alternative, left over from an Airfix Hs 123, which would round up the aircraft’s somewhat vintage look. Because the wheels were missing, I inserted two Matchbox MiG-21 wheels (which were left over in the spares bin from two different kits, though). The tail wheel came from an Academy Fw 190.
Cowling and engine inside (thankfully a 9-cylinder radial that could pose as a Mercury) were taken OOB, just the original two-blade propeller was replaced with a more appropriate three-blade alternative, IIRC from a Hobby Boss Grumman F4F. The cockpit was taken OOB, and I also used the two pilot figures from the kit. The rear crew member just had the head re-positioned to look sideways, and had to have the legs chopped off because there’s hardly and space under the desk with the radio set he’s sitting at.
The ventral 500 kg bomb came from a Matchbox Ju 87, the bomb arms are Fw 189 landing gear parts. Additional underwing pylons came from an Intech P-51, outfitted with 50 kg bombs of uncertain origin (they look as if coming from an old Hasegawa kit). The protruding machine gun barrel fairings on the wings were scratched from styrene rod material, with small holes drilled into them.
A real Frankenstein creation, but it does not look bad or implausible!
Painting and markings:
I gave the B 9 a camouflage that was carried by some Flygvapnet aircraft in the late Thirties, primarily by fighters imported from the United States but also some bombers like the B 3 (Ju 86). The IMHO quite attractive scheme consists on the upper surfaces of greenish-yellow zinc chromate primer (Humbrol 81, FS 33481), on top of which a dense net of fine dark green wriggles (supposed to be FS 34079, but I rather used Humbrol 163, RAF Dark Green, because it is more subdued) was manually applied with a thin brush, so that the primer would still shine through, resulting in a mottled camouflage.
On the real aircraft, this was sealed with a protective clear lacquer to which 5% of the dark green had been added, and I copied this procedure on the model, too, using semi-gloss acrylic varnish with a bit of Revell 46 added. The camouflage was wrapped around the wings’ leading edges and the spatted landing gear was painted with the upper camouflage, too.
The undersides were painted with Humbrol 87 (Steel Grey), to come close to the original blue-grey tone, which is supposed to be FS 35190 on this type of camouflage. The tone is quite dark, almost like RAF PRU Blue.
The interior was painted – using a Saab J 21 cockpit as benchmark – in a dark greenish grey (RAL 7009).
The model received the usual light black ink washing and some post-panel shading on the lower surfaces, because this effect would hardly be recognizable on the highly fragmented upper surface.
The markings are reflecting Flygvapnet’s m/37 regulations, from the direct pre-WWII era when the roundels had turned from black on white to yellow on blue but still lacked the yellow edge around the roundel for more contrast. F6 Västgöta flygflottilj was chosen because it was a dive bomber unit in the late Thirties, and the individual aircraft code (consisting of large white two-digit numbers) was added with the fin and the front of the fuselage. “27” would indicate an aircraft of the unit’s 2nd division, which normally had blue as a standardized color code, incorporated through the blue bands on the spats and the small "2nd div." tag on the rudder (from a contemporary F8 Swedish Gladiator).
Roundels and codes came from an SBS Models sheet, even though they belong to various aircraft types. Everything was finally sealed with matt acrylic varnish.

The A-14 program originally started in 2005 as a private venture, initiated by Northrop-Grumman together with the Elbit Group as a joint venture through Elbit’s Texas-based aircraft division M7 Aerosystems, an approved supplier to major aerospace clients. The aircraft was intended to replace the USAF’s A-10 attack aircraft as well as early F-16s in the strike role from 2010 onwards. The time slot for the project turned out to be advantageous, because at that time the USAF was contemplating to replace the simple and sturdy A-10 with the much more complex F-35, eventually even with its VTOL variant, and the highly specialized F-117 was retired, too.
The A-14 revived conceptual elements of Grumman’s stillborn A-12 stealth program for the US Navy, which had also been part of the USAF’s plans to replace the supersonic F-111 tactical bomber, but on a less ambitious and expensive level concerning technology, aiming for a more effective compromise between complexity, survivability and costs. The basic idea was an updated LTV A-7D (the A-10’s predecessor from the Vietnam War era), which had far more sophisticated sensor and navigation equipment than the rather simple but sturdy A-10, but with pragmatic stealth features and a high level of survivability in a modern frontline theatre or operations.
M7 Aerosystems started on a blank sheet, even though Northrop-Grumman’s A-12 influence was clearly visible, and to a certain degree the aircraft shared the basic layout with the F-117A. The A-14 was tailored from the start to the ground attack role, and therefore a subsonic design. Measures to reduce radar cross-section included airframe shaping such as alignment of edges, fixed-geometry serpentine inlets that prevented line-of-sight of the engine faces from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and maintenance covers that could provide a radar return. The A-14 was furthermore designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye.
The resulting airframe was surprisingly large for an attack aircraft – in fact, it rather reminded of a tactical bomber in the F-111/Su-24 class than an alternative to the A-10. The A-14 consisted of a rhomboid-shaped BWB (blended-wing-and-body) with extended wing tips and only a moderate (35°) wing sweep, cambered leading edges, a jagged trailing edge and a protruding cockpit section which extended forward of the main body.
The majority of the A-14’s structure and surface were made out of a carbon-graphite composite material that is stronger than steel, lighter than aluminum, and absorbs a significant amount of radar energy. The central fuselage bulge ended in a short tail stinger with a pair of swept, canted fins as a butterfly tail, which also shrouded the engine’s hot efflux. The fins could have been omitted, thanks to the aerodynamically unstable aircraft’s fly-by-wire steering system, and they effectively increased the A-14’s radar signature as well as its visual profile, but the gain in safety in case of FBW failure or physical damage was regarded as a worthwhile trade-off. Due to its distinctive shape and profile, the A-14 quickly received the unofficial nickname “Squatina”, after the angel shark family.
The spacious and armored cockpit offered room for the crew of two (pilot and WSO or observer for FAC duties), seated side-by-side under a generous glazing, with a very good field of view forward and to the sides. The fuselage structure was constructed around a powerful cannon, the five-barrel GAU-12/U 25 mm ‘Equalizer’ gun, which was, compared with the A-10’s large GAU-8/A, overall much lighter and more compact, but with only little less firepower. It fired a new NATO series of 25 mm ammunition at up to 4.200 RPM. The gun itself was located under the cockpit tub, slightly set off to port side, and the front wheel well was offset to starboard to compensate, similar in arrangement to the A-10 or Su-25. The gun’s ammunition drum and a closed feeding belt system were located behind the cockpit in the aircraft’s center of gravity. An in-flight refueling receptor (for the USAF’s boom system) was located in the aircraft’s spine behind the cockpit, normally hidden under a flush cover.
Due to the gun installation in the fuselage, however, no single large weapon bay to minimize radar cross section and drag through external ordnance was incorporated, since this feature would have increased airframe size and overall weight. Instead, the A-14 received four, fully enclosed compartments between the wide main landing gear wells and legs. The bays could hold single iron bombs of up to 2.000 lb caliber each, up to four 500 lb bombs or CBUs, single laser-guided GBU-14 glide bombs, AGM-154 JSOW or GBU-31/38 JDAM glide bombs, AGM-65 Maverick guided missiles or B61 Mod 11 tactical nuclear weapons, as well as the B61 Mod 12 standoff variant, under development at that time). Retractable launch racks for defensive AIM-9 Sidewinder air-to-air missiles were available, too, and additional external pylons could be added, e.g. for oversize ordnance like AGM-158C Long Range Anti-Ship Missile (LRASM) or AGM-158 Joint Air to Surface Standoff Missile (JASSM), or drop tanks for ferry flights. The total in- and external ordnance load was 15,000 lb (6,800 kg).
The A-14 was designed with superior maneuverability at low speeds and altitude in mind and therefore featured a large wing area, with high wing aspect ratio on the outer wing sections, and large ailerons areas. The ailerons were placed at the far ends of the wings for greater rolling moment and were split, making them decelerons, so that they could also be used as air brakes in flight and upon landing.
This wing configuration promoted short takeoffs and landings, permitting operations from primitive forward airfields near front lines. The sturdy landing gear with low-pressure tires supported these tactics, and a retractable arrester hook, hidden by a flush cover under the tail sting, made it possible to use mobile arrested-recovery systems.
The leading edge of the wing had a honeycomb structure panel construction, providing strength with minimal weight; similar panels covered the flap shrouds, elevators, rudders and sections of the fins. The skin panels were integral with the stringers and were fabricated using computer-controlled machining, reducing production time and cost, and this construction made the panels more resistant to damage. The skin was not load-bearing, so damaged skin sections could be easily replaced in the field, with makeshift materials if necessary.
Power came from a pair of F412-GE-114 non-afterburning turbofans, engines that were originally developed for the A-12, but de-navalized and lightened for the A-14. These new engines had an output of 12,000 lbf (53 kN) each and were buried in blended fairings above the wing roots, with jagged intakes and hidden ducts. Flat exhausts on the wings’ upper surface minimized both radar and IR signatures.
Thanks to the generous internal fuel capacity in the wings and the fuselage, the A-14 was able to loiter and operate under 1,000 ft (300 m) ceilings for extended periods. It typically flew at a relatively low speed of 300 knots (350 mph; 560 km/h), which made it a better platform for the ground-attack role than fast fighter-bombers, which often have difficulty targeting small, slow-moving targets or executing more than just a single attack run on a selected target.
A mock-up was presented and tested in the wind tunnel and for radar cross-section in late 2008. The A-14’s exact radar cross-section (RCS) remained classified, but in 2009 M7 Aerosystems released information indicating it had an RCS (from certain angles) of −40 dBsm, equivalent to the radar reflection of a "steel marble". With this positive outcome and the effective design, M7 Aerosystems eventually received federal funding for the production of prototypes for an official DT&E (Demonstration Testing and Evaluation) program.
Three prototypes/pre-production aircraft were built in the course of 2010 and 2011, and the first YA-14 made its maiden flight on 10 May 2011. The DT&E started immediately, and the machines (a total of three flying prototypes were completed, plus two additional airframes for static tests) were gradually outfitted with mission avionics and other equipment. This included GPS positioning, an inertial navigation system, passive sensors to detect radar usage, a small, gyroscopically stabilized turret, mounted under the nose of the aircraft, containing a FLIR boresighted with a laser spot-tracker/designator, and an experimental 3-D laser scanning LIDAR in the nose as a radiation-less alternative to a navigation and tracking radar.
Soon after the DT&E program gained momentum in 2012, the situation changed for M7 Aerosystems when the US Air Force considered the F-35B STOVL variant as its favored replacement CAS aircraft, but concluded that the aircraft could not generate a sufficient number of sorties. However, the F-35 was established as the A-14’s primary rival and remained on the USAF’s agenda. For instance, at that time the USAF proposed disbanding five A-10 squadrons in its budget request to cut its fleet of 348 A-10s by 102 to lessen cuts to multi-mission aircraft in service that could replace the specialized attack aircraft.
In August 2013, Congress and the Air Force examined various proposals for an A-10 replacement, including the A-14, F-35 and the MQ-9 Reaper unmanned aerial vehicle, and, despite the A-14’s better qualities in the ground attack role, the F-35 came out as the overall winner, since it was the USAF’s favorite. Despite its complexity, the F-35 was – intended as a multi-role tri-service aircraft and also with the perspective of bigger international sales than the more specialized A-14 – regarded as the more versatile and, in the long run, more cost-efficient procurement option. This sealed the A-14’s fate and the F-35A entered service with U.S. Air Force F-35A in August 2016 (after the F-35B was introduced to the U.S. Marine Corps in July 2015). At that time, the U.S. planned to buy 2,456 F-35s through 2044, which would represent the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps for several decades.
Since the A-14’s technology was considered to be too critical to be marketed to export customers (Israel showed early interest in the aircraft, as well as South Korea), the program was cancelled in 2016.

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.
Painting and markings:
For a stealth aircraft and a prototype I wanted something subdued or murky, but not an all-black or -grey livery. I eventually settled for the rather dark paint scheme that the USAF applied to its late B-52Gs and the B-1Bs, which consists of two tones from above, FS 36081 (Dark Grey, a.k.a. Dark Gunship Grey) and 34086 (Green Drab), and underneath (FS 36081 and 36118 (Gunship Grey). The irregular pattern was adapted (in a rather liberal fashion) from the USAF’s early B-1Bs, using Humbrol 32, 108 and 125 as basic colors. The 108 turned out to be too bright, so I toned it down with an additional coat of thinned Humbrol 66. While this considerably reduced the contrast between the green and the grey, the combination looks much better and B-1B-esque.
The wings’ leading edges were painted for more contrast with a greyish black (Tar Black, Revell 09), while the landing gear, the interior of the air intakes and the open bomb bay became glossy white. The cockpit was painted in medium grey (Humbrol 140) and the clear parts received a thinned inner coating with a mix of transparent yellow and brown, simulating an anti-radar coating – even though the effect turned out to be minimal, now it looks as of the plastic parts had just yellowed from age…
After the initial livery had been finished the model received a black ink washing and some post-panel shading with slightly brightened variations of the basic tones (using Humbrol 79, 144 and 224). Decals were added next, an individual mix from various sources. The “Stars-and-Bars” come from a PrintScale A-7 sheet, most stencils come from an F-16 sheet.
After some more detail painting and a treatment with graphite on the metal areas (exhausts, gun port), the model was sealed with matt acrylic varnish (Italeri).
Batman’s next Batwing? Maybe, there’s certainly something fictional about this creation. But the “Squatina” turned out much more conclusive (and even pretty!) than I expected, even though it became a bigger aircraft than intended. And I am positively surprised how good the bodywork became – after all, lots of putty had to be used to fill all the gaps between parts that no one ever expected to be grafted together.

15,000 lb (6,800 kg) and provisions to carry/deploy a wide range of ordnance
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.
Painting and markings:
For a stealth aircraft and a prototype I wanted something subdued or murky, but not an all-black or -grey livery. I eventually settled for the rather dark paint scheme that the USAF applied to its late B-52Gs and the B-1Bs, which consists of two tones from above, FS 36081 (Dark Grey, a.k.a. Dark Gunship Grey) and 34086 (Green Drab), and underneath (FS 36081 and 36118 (Gunship Grey). The irregular pattern was adapted (in a rather liberal fashion) from the USAF’s early B-1Bs, using Humbrol 32, 108 and 125 as basic colors. The 108 turned out to be too bright, so I toned it down with an additional coat of thinned Humbrol 66. While this considerably reduced the contrast between the green and the grey, the combination looks much better and B-1B-esque.
The wings’ leading edges were painted for more contrast with a greyish black (Tar Black, Revell 09), while the landing gear, the interior of the air intakes and the open bomb bay became glossy white. The cockpit was painted in medium grey (Humbrol 140) and the clear parts received a thinned inner coating with a mix of transparent yellow and brown, simulating an anti-radar coating – even though the effect turned out to be minimal, now it looks as of the plastic parts had just yellowed from age…
After the initial livery had been finished the model received a black ink washing and some post-panel shading with slightly brightened variations of the basic tones (using Humbrol 79, 144 and 224). Decals were added next, an individual mix from various sources. The “Stars-and-Bars” come from a PrintScale A-7 sheet, most stencils come from an F-16 sheet.
After some more detail painting and a treatment with graphite on the metal areas (exhausts, gun port), the model was sealed with matt acrylic varnish (Italeri).
Batman’s next Batwing? Maybe, there’s certainly something fictional about this creation. But the “Squatina” turned out much more conclusive (and even pretty!) than I expected, even though it became a bigger aircraft than intended. And I am positively surprised how good the bodywork became – after all, lots of putty had to be used to fill all the gaps between parts that no one ever expected to be grafted together.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
The A-14 program originally started in 2005 as a private venture, initiated by Northrop-Grumman together with the Elbit Group as a joint venture through Elbit’s Texas-based aircraft division M7 Aerosystems, an approved supplier to major aerospace clients. The aircraft was intended to replace the USAF’s A-10 attack aircraft as well as early F-16s in the strike role from 2010 onwards. The time slot for the project turned out to be advantageous, because at that time the USAF was contemplating to replace the simple and sturdy A-10 with the much more complex F-35, eventually even with its VTOL variant, and the highly specialized F-117 was retired, too.
The A-14 revived conceptual elements of Grumman’s stillborn A-12 stealth program for the US Navy, which had also been part of the USAF’s plans to replace the supersonic F-111 tactical bomber, but on a less ambitious and expensive level concerning technology, aiming for a more effective compromise between complexity, survivability and costs. The basic idea was an updated LTV A-7D (the A-10’s predecessor from the Vietnam War era), which had far more sophisticated sensor and navigation equipment than the rather simple but sturdy A-10, but with pragmatic stealth features and a high level of survivability in a modern frontline theatre or operations.
M7 Aerosystems started on a blank sheet, even though Northrop-Grumman’s A-12 influence was clearly visible, and to a certain degree the aircraft shared the basic layout with the F-117A. The A-14 was tailored from the start to the ground attack role, and therefore a subsonic design. Measures to reduce radar cross-section included airframe shaping such as alignment of edges, fixed-geometry serpentine inlets that prevented line-of-sight of the engine faces from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and maintenance covers that could provide a radar return. The A-14 was furthermore designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye.
The resulting airframe was surprisingly large for an attack aircraft – in fact, it rather reminded of a tactical bomber in the F-111/Su-24 class than an alternative to the A-10. The A-14 consisted of a rhomboid-shaped BWB (blended-wing-and-body) with extended wing tips and only a moderate (35°) wing sweep, cambered leading edges, a jagged trailing edge and a protruding cockpit section which extended forward of the main body.
The majority of the A-14’s structure and surface were made out of a carbon-graphite composite material that is stronger than steel, lighter than aluminum, and absorbs a significant amount of radar energy. The central fuselage bulge ended in a short tail stinger with a pair of swept, canted fins as a butterfly tail, which also shrouded the engine’s hot efflux. The fins could have been omitted, thanks to the aerodynamically unstable aircraft’s fly-by-wire steering system, and they effectively increased the A-14’s radar signature as well as its visual profile, but the gain in safety in case of FBW failure or physical damage was regarded as a worthwhile trade-off. Due to its distinctive shape and profile, the A-14 quickly received the unofficial nickname “Squatina”, after the angel shark family.
The spacious and armored cockpit offered room for the crew of two (pilot and WSO or observer for FAC duties), seated side-by-side under a generous glazing, with a very good field of view forward and to the sides. The fuselage structure was constructed around a powerful cannon, the five-barrel GAU-12/U 25 mm ‘Equalizer’ gun, which was, compared with the A-10’s large GAU-8/A, overall much lighter and more compact, but with only little less firepower. It fired a new NATO series of 25 mm ammunition at up to 4.200 RPM. The gun itself was located under the cockpit tub, slightly set off to port side, and the front wheel well was offset to starboard to compensate, similar in arrangement to the A-10 or Su-25. The gun’s ammunition drum and a closed feeding belt system were located behind the cockpit in the aircraft’s center of gravity. An in-flight refueling receptor (for the USAF’s boom system) was located in the aircraft’s spine behind the cockpit, normally hidden under a flush cover.
Due to the gun installation in the fuselage, however, no single large weapon bay to minimize radar cross section and drag through external ordnance was incorporated, since this feature would have increased airframe size and overall weight. Instead, the A-14 received four, fully enclosed compartments between the wide main landing gear wells and legs. The bays could hold single iron bombs of up to 2.000 lb caliber each, up to four 500 lb bombs or CBUs, single laser-guided GBU-14 glide bombs, AGM-154 JSOW or GBU-31/38 JDAM glide bombs, AGM-65 Maverick guided missiles or B61 Mod 11 tactical nuclear weapons, as well as the B61 Mod 12 standoff variant, under development at that time). Retractable launch racks for defensive AIM-9 Sidewinder air-to-air missiles were available, too, and additional external pylons could be added, e.g. for oversize ordnance like AGM-158C Long Range Anti-Ship Missile (LRASM) or AGM-158 Joint Air to Surface Standoff Missile (JASSM), or drop tanks for ferry flights. The total in- and external ordnance load was 15,000 lb (6,800 kg).
The A-14 was designed with superior maneuverability at low speeds and altitude in mind and therefore featured a large wing area, with high wing aspect ratio on the outer wing sections, and large ailerons areas. The ailerons were placed at the far ends of the wings for greater rolling moment and were split, making them decelerons, so that they could also be used as air brakes in flight and upon landing.
This wing configuration promoted short takeoffs and landings, permitting operations from primitive forward airfields near front lines. The sturdy landing gear with low-pressure tires supported these tactics, and a retractable arrester hook, hidden by a flush cover under the tail sting, made it possible to use mobile arrested-recovery systems.
The leading edge of the wing had a honeycomb structure panel construction, providing strength with minimal weight; similar panels covered the flap shrouds, elevators, rudders and sections of the fins. The skin panels were integral with the stringers and were fabricated using computer-controlled machining, reducing production time and cost, and this construction made the panels more resistant to damage. The skin was not load-bearing, so damaged skin sections could be easily replaced in the field, with makeshift materials if necessary.
Power came from a pair of F412-GE-114 non-afterburning turbofans, engines that were originally developed for the A-12, but de-navalized and lightened for the A-14. These new engines had an output of 12,000 lbf (53 kN) each and were buried in blended fairings above the wing roots, with jagged intakes and hidden ducts. Flat exhausts on the wings’ upper surface minimized both radar and IR signatures.
Thanks to the generous internal fuel capacity in the wings and the fuselage, the A-14 was able to loiter and operate under 1,000 ft (300 m) ceilings for extended periods. It typically flew at a relatively low speed of 300 knots (350 mph; 560 km/h), which made it a better platform for the ground-attack role than fast fighter-bombers, which often have difficulty targeting small, slow-moving targets or executing more than just a single attack run on a selected target.
A mock-up was presented and tested in the wind tunnel and for radar cross-section in late 2008. The A-14’s exact radar cross-section (RCS) remained classified, but in 2009 M7 Aerosystems released information indicating it had an RCS (from certain angles) of −40 dBsm, equivalent to the radar reflection of a "steel marble". With this positive outcome and the effective design, M7 Aerosystems eventually received federal funding for the production of prototypes for an official DT&E (Demonstration Testing and Evaluation) program.
Three prototypes/pre-production aircraft were built in the course of 2010 and 2011, and the first YA-14 made its maiden flight on 10 May 2011. The DT&E started immediately, and the machines (a total of three flying prototypes were completed, plus two additional airframes for static tests) were gradually outfitted with mission avionics and other equipment. This included GPS positioning, an inertial navigation system, passive sensors to detect radar usage, a small, gyroscopically stabilized turret, mounted under the nose of the aircraft, containing a FLIR boresighted with a laser spot-tracker/designator, and an experimental 3-D laser scanning LIDAR in the nose as a radiation-less alternative to a navigation and tracking radar.
Soon after the DT&E program gained momentum in 2012, the situation changed for M7 Aerosystems when the US Air Force considered the F-35B STOVL variant as its favored replacement CAS aircraft, but concluded that the aircraft could not generate a sufficient number of sorties. However, the F-35 was established as the A-14’s primary rival and remained on the USAF’s agenda. For instance, at that time the USAF proposed disbanding five A-10 squadrons in its budget request to cut its fleet of 348 A-10s by 102 to lessen cuts to multi-mission aircraft in service that could replace the specialized attack aircraft.
In August 2013, Congress and the Air Force examined various proposals for an A-10 replacement, including the A-14, F-35 and the MQ-9 Reaper unmanned aerial vehicle, and, despite the A-14’s better qualities in the ground attack role, the F-35 came out as the overall winner, since it was the USAF’s favorite. Despite its complexity, the F-35 was – intended as a multi-role tri-service aircraft and also with the perspective of bigger international sales than the more specialized A-14 – regarded as the more versatile and, in the long run, more cost-efficient procurement option. This sealed the A-14’s fate and the F-35A entered service with U.S. Air Force F-35A in August 2016 (after the F-35B was introduced to the U.S. Marine Corps in July 2015). At that time, the U.S. planned to buy 2,456 F-35s through 2044, which would represent the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps for several decades.
Since the A-14’s technology was considered to be too critical to be marketed to export customers (Israel showed early interest in the aircraft, as well as South Korea), the program was cancelled in 2016.

Some background:
The Su-21 attack aircraft had its roots in the Su-15 interceptor, which itself was a development of Sukhoi's tailed-delta Su-9 and Su-11 interceptor fighters. Construction of the Su-15 (internal project designation T-58) began in mid-1960, state acceptance tests of the respective T-58-8M1 interception complex with radar and air-to-air missiles started in August 1963.
In 1966 series production at Novosibirsk began, the first pre-series Su-15 interceptor made its first flight from Novosibirsk on 6 March 1966. Once identified as a new service aircraft, NATO christened the type 'Flagon'. While the Su-15 was in series production, a number of improved design features were developed, tested and subsequently introduced with a new production series of the interceptor.
In 1969, under the influence of the Vietnam conflict and the conclusion that dedicated ground attack aircraft were needed in a modern battlefield, the Sukhoi OKB investigated options for a new close-support "mudfighter" aircraft. One option was a derivative of the Su-15, designated the "T-58Sh" -- the suffix "Sh" stood for "shturmovik (storm bird)", a general Soviet name for a close-support aircraft.
The T-58Sh design was based on the Su-15 fuselage and engine installation with two Tumansky R-13-300 turbojets, but with considerable modifications. These included totally new wings and stabilizers - the orginal delta wing for high speed gave way to tapered wings with a constant 40° sweep, and the horizontal stabilizers were modified, too. The original fin was kept, though, as well as most of the landing gear installation, even though the front wheel retracted backwards now, since the complete nose up until spar no. 10 had been redesigned: instead of the interceptor's large radome, a slanted, considerably shorter nose improved the field of view for the pilot. In its tip it housed a 'Fon' laser rangefinder as well as a missile guidance antenna. A Doppler radar was housed under the nose, too, and an ASP-PF gunsight and a PBK-2 bomb sight optimized for lob-bombing were installed. The cockpit was completely armored, as well as parts of the lower fuselage around the engine section. All internal tanks (holding 4.500kg/9.921lb of fuel in the fuselage as well as in the wings) were self-sealing.
Another novelty was the freshly developed, built-in Gatling cannon, the GSh-30A, also known as 9A-621. This formidable, six-barreled weapon had a pneumatic mechanism (instead of en electric system, which was used in US types like the M61 'Vulcan' gun), fired 30mm shells and achieved a staggering fire rate of 5.000rpm. The cannon's magazine held 280 rounds - a shift of fuel tanks from the fuselage into the new wings with more internal space allowed the belly installation behind the front wheel well. Furthermore, a total of nine external weapon hardpoints allowed an ordnance load of up to 5.500kg (12.115lb), which included laser-guided smart bombs/missiles as well as tactical nuclear weapons.
Two T-58Sh prototypes were completed, and the first of these flew on 6 April 1968, the second on 26 September 1968. After State Acceptance Trials the Su-15Sh entered service in 1970 - in parallel, OKB Mikoyan was also working on a ground attack variant of its MiG-23 VG fighter, the later MiG-27, which flew in 1971 for the first time.
This advantage in time to service worked in favor of the Suchoj aircraft, which was so different from its Su-15 origins that it received a new service-designation, Su-21 (which was, by Western observers, often miss-attributed to the late Su-15 interceptor versions with ogive radomes and new double-delta wings).
By 1972, four squadrons were equipped with the new aircraft. Interestingly, none of the Su-21 were deployed to Afghanistan. Instead, the new fighter bombers were exclusively allocated to Attack Regiments in the potential Western conflict theatre, two of them based in Poland and two in Eastern Germany.
The basic version of the aircraft was produced at Factory 31, at Tbilisi, in the Soviet Republic of Georgia. Between 1969 and 1975, 182 Su-21 were produced. Much like the Su-15 interceptor variants, there were no exports, the Soviet/Russian Air Force remained the only operator - the more versatile MiG-23/27 filled that role. Later, foreign customers would receive the Su-25K from Sukhoi's export program, as well as the Su-20 and 22 VG fighter bombers.
During its service career, the Su-21 was constantly upgraded. One of the most significant changes was an MLU programme which, among others, introduced the 'Shkval' optical TV and aiming system, which was coupled with a new 'Prichal' laser rangefinder and target designator in an enlarged nosecone. This system enabled the aircraft to carry out all-weather missions, day and night, and also allowed to deploy the new 'Vikhr' laser-guided, tube-launched missiles, which were very effective against armored vehicles.
These updated aircraft received the designation Su-21D ('dorabotanyy' = updated). Two respective prototypes were built in 1982–84, and all aircraft were brought to this standard until 1988.
The only engagement of the Su-21 in a real combat scenario was its employment during the First Chechen War - which also signalized the type's retirement, after the conflict was over. Together with other Russian Air Force air assets, The Su-21s achieved air supremacy for Russian Forces, destroying up to 266 Chechen aircraft on the ground. The entire Air Force assets committed to the Chechen campaign between 1994 and 1996 performed around 9,000 air sorties, with around 5,300 being strike sorties. The 4th Russian Air Army had 140 Su-17Ms, Su-21Ds, Su-24s and Su-25s in the warzone supported by an A-50 AWACS aircraft. The employed munitions were generally unguided bombs and rockets with only 2.3% of the strikes using precision-guided munitions.
The Su-21 was a controversial aircraft. It was relatively reliable, benefitting from its two engines and solid armor, which was seen as one of the most important features for a true battlefield aircraft - inofficially, it was nicknamed 'ома́р' ('lobster') among the crews.
It had a high payload and was a very stable weapon platform. But the type suffered from the fact that it was an interceptor derivate which had originally been designed for dashes at Mach 2.5 at high altitudes. Consequently, the airframe had to be enforced to withstand higher G loads at low level flight and with heavy external loads, so that it was basically overweight. The extra armor did not help much either.
Additionally, the R-13 jet engines (basically the same that powered the 3rd generation MiG-21MF) were thirsty, even when running without the afterburner extra power, so that the type's range was very limited. Its ability to dash beyond Mach 1 even at low altitudes was of little tactical use, even though its high rate of acceleration and climb made it ideal for suprise attacks and delivery of tactical nuclear weapons - the latter was the main reason why the type was kept in service for so long until it was replaced by Su-24 bombers in this role.
Another source of constant trouble was the GSh-30A cannon. While its firepower was overwhelming, the vibrations it caused while firing and the pressure blasts from the nozzles could badly damage the aircraft's lower fuselage. There had been several incidents when the front wheel covers had literally been blown apart, and in one case the gun itself detached from its fuselage mount while firing - hitting the aircraft itself from below!
In the end, the Su-21 could not live up to the expectations of its intended role - even though this was less the aircraft's fault: the military demands had been unclear from the beginning, and the T-58Sh had been a second- choice solution to this diffuse performance profile.
Eventually the MiG-27 and also the Su-17/22 family as well as the biggher Su-24 tactical bomber, thanks to their variable geometry wings, proved to be the more flexible aircraft for the ground attack/fighter bomber role. But the lessons learned from the Su-21 eventually found their way into the very successful, subsonic Su-25 ('Frogfoot') family. The last Su-21D was retired in January 1997, after a service career of 25 years.

The kit and its assembly:
This whif actually has a real background, as outlined above - OKB Sukhoi actually worked in the late 60ies on a Su-15 derivate as a specialized attack aircraft, since the Soviet Forces lacked that type. The ground attack types then in service were the vintage MiG-17 and converted MiG-19 fighters, as well as the fast but very limited Su-7 - either outdated fighters or a fighter-bomber with insufficient range and payload.
Specifications for a ground attack aircraft were unclear at that time, though. Supersonic capability was still seen as a vital asset for any military aircraft, and WWII tactics were still the basis for close air support duties. The T-58Sh was eventually one design direction that would keep development time and costs low, starting with a proven basic airframe and adapting it to a new (and very different) role.
The Su-15, from which the T-58Sh was derived, originally was a Mach 2 interceptor, solely armed with missiles. Making THIS a ground attack aircraft surely was a huge step. The projected Su-15Sh, how the aircrfat was also called, was still to be supersonic, since this was seen as a vital asset at that time. This concept would eventually be a dead end, though, or, alternatively, result in the lighter and much cheaper MiG-27 tactical fighter in the 70ies. But it should still take some more years until a subsonic, simple and dedicated aircraft (the T-8, which made its maiden flight in 1975 and became later the Su-25 'Frogfoot') would be the 'right' direction for the new shturmovik. The Su-15Sh actually never left the drawing board, the swing-wing Su-17/20/22 more or less took its place in real life.
With that background my idea was to build a model of the ground attack Su-15 derivate in front line service in the mid 80ies, at the Cold War's peak and used by the Group of Soviet Forces in (Eastern) Germany. The Su-21 designation is fictional. But since the aircraft would be SO different from the Su-15 interceptor I can hardly imagine that it would have been called Su-15Sh in service. Since its cousin, the MiG-27, also received a new designation, I decided to apply the Su-21 code (which was never applied to a real aircraft - those Su-15 versions called Su-21 are just misnomers or speculations of Western 'experts' when the Iron Curtain was still up).
As a coincidence, I had all 'ingredients' at hand:
● Fuselage and fin from a PM Model Su-15
● Nose section from an Academy MiG-27 (leftover from the Q-6 kitbach)
● Wings and horizontal stabilizers from an ESCI A-7
The A-7 wings have slightly more sweep than what the drafted T-58Sh had (45° vs. 40°), as far as I can tell from profiles, but otherwise they fit in shape and size. I just cut the orginal leading edge away, sculpted a new front from putty, and the result looked very good.
What became tricky were the landing gear wells. Part of the Su-15 landing gear retracts into the lower fuselage, and mating this with the Corsair's wings and the potential space for the landing gear there did not match up properly -the wings would end up much too far behind.
After some trials I decided to cut out the landing gear wells on the lower side of the wings, relatively far forward, and cut out a part of the lower fuselage, reversed it, so that the landing gear wells woukd be placed about 5mm further forward, and the wings were finally attached to the fuselage so that these would match the respective openings on the fuselage's bottom. This was more or less the only major and unexpected surgery, and the original Su-15 landing gear could be retained.
Using the A-7's stabilizers was also a bit off the original concept (the T-58Sh appeared to keep the original parts), but I found that the more slender but wider A-7 parts just made the aircraft look more homogenous?
Grafting the MiG-27 cockpit (which was taken OOB) onto the fuselage was not a big problem, since the intersection is of simple shape and fits well by height and width. I made a vertical cut on the Su-15 fuselage in the middle of the air intake area, which would later be hidden through the air intakes. The latter were taken from the Su-15, but simplified: the intake became simple and "vertical", and the large, orginal splitter plates were replaced by the shorter speiceimen from the MiG-27 kit. The fit almost perfectly, are just a bit short, so that a small hole had to be filled with styrene strips on the lower side.
The fin was taken OOB, just as on the propsed real aircraft. The resulting side profile reminds VERY much of a Dassault Étendard on steroids...? The whole thing also looks a bit like the missing link between the Su-15 and the later Su-24 fighter bomber - esp. when you know the Fencer's fixed-wing T-6 prototype.
Externally, the gatling gun (also taken from the leftoevr MiG-27) and a total of nine hardpoints were added - three under the fuselage, flanking the gun, and six under the outer wings.
Since the Su 15 is a pretty large aircraft, I used the opportunity to equip the aircraft with serious air-to-ground ordnance, a pair of TV-guided Kh-29T (AS-14 "Kedge") missiles from an ICM USSR weapon set and a pair of R-60 AAMs, leftover from an ESCI Ka-34. Furthermore, chaff/flare dispensers were added to the rear upper fuselage, as well as some antennae and the pitots.
Actually, this kitbash was less complicated as expected. Needed lots of putty, sure, but this would also have been needed on the OOB Su-15 from PM Models, as it is a primitive and crude model kit. Here, it found a good use. One drawback is, though, that the surface lacks detail: the PM Model Su-15 is bleak (to put it mildly), and the re-used A-7 wings lost much of their engraved details to leftover paint or sanding - paint tricks would have to mend this.
Painting and markings:
As a frontline service aircraft, this one would receive a tactical camouflage pattern. The Soviet Air Force offers a wide range of options, ranging from boring to bizarre, and I settled for a typical four-color camouflage with light blue undersides:
● Humbrol 119 (Light Earth)
● Humbrol 159 (Khaki Drab)
● Humbrol 195 (Chrome Oxide Green, RAL 6020)
● Testors 2005 (Burnt Umber)
● Humbrol 115 (Russian Blue) for the lower surfaces
The paint scheme was inspired by a East Germany-based Su-17, the colors are guesstimates, based on pictures of real-life Soviet aircraft.
Cockpit interior was painted in typical, infamous Soviet/Russian turqoise (*Argh*), the complete landing gear was painted in Aluminum (Humbrol 56); the wheel discs became bright green (Humbrol 131), di-electric panels (e .g. the fin tip) received a coat in Forest Green (Humbrol 149, FS 34092).
The model was weathered through some counter-shading with lighter tones of the five basic colors, a wash with black ink and some additional stains and blotches with different shades of green and brown, including Humbrol 98 118, 128, 151 - even some RLM 82 from Testors found its way onto the aircraft!
Decals and markings were puzzled together from various aftermarket sheets, and are based on real life pictures of Soviet/Russian aircraft based in Eastern Germany.
I also added some bare metal stains at the leading edges and soot stains around the gun. Since the kitbashed model was pretty bleak, I tried to add painted panel lines - using a thin brush and a mix of matt varnish and black. The counter-shading applied before enhances this effect, and if you do not look too closely at the model, the result is O.K.
Finally, everything was sealed under a coat of matt acrylic varnish.

Some background:
The Yakovlev Yak-38 (Russian: Яковлева Як-38; NATO reporting name: "Forger") was the Soviet Naval Aviation's first and only operational VTOL strike fighter aircraft, in addition to being its first operational carrier-based fixed-wing aircraft. It was developed specifically for and served almost exclusively on the Kiev-class aircraft carriers.
Some specimen of the initial variant were tested during the Soviet Union's intervention in Afghanistan. These trials revealed several weaknesses of the construction in the form of unacceptable hot and high capabilities as well as a low payload. A further development for the Soviet Navy was therefore decided in August 1981, the abilities of which were fixed in October 1982. Already in November 1982 the first flight experiments of the prototype, leading to the Yak-38M, took place. In mid-1983 the manufacturing tests were completed and the production release was granted.
Anyway, the Soviet Air Force also had interest in a VTOL attack aircraft, which could provide CAS duties in immediate front line theatres, complementing the new Suchoj Su-25 Frogfoot and various attack helicopter types - but the Yak-38 was outright rejected. The Frontal Aviation demanded a much better performance, a dedicated avionics suite for ground attack duties and a higher payload of at least 2.500 kg (5.500 lb) in VTOL mode, plus an internal gun, and 3.000 kg (6.600 lb) when operating in C/STOL mode at sea level and from semi-prepared airstrips. For its primary ground attack role, the machine was also to be armored against projectiles of up to 0.5” around the lower hull and against 20mm rounds in the cockpit section. Finally, the machine had to be, compared with the Yak-38, simplified and be more rugged in order to ease frontline service and endure survivability.
OKB Yakovlev accepted the challenge and dusted off studies that had been undertaken during the Yak-38’s design stage. One of these was the Yak-38L (for 'lift/cruise'), a design built around a single, modified the AL-21F turbojet with vectoring nozzles and no lift engines, which were just dead weight in normal flight. This route seemed to be the most promising option for the Frontal Aviation's demands, even though it would mean a severe re-construction of the airframe.
The new aircraft, internally referred to as 'Izdeliye 138', was based on the Yak-38 airframe, but adapted and literally built around a lift/cruise variant of the large Kuznetsov NK-32 low bypass turbofan engine (originally, with an afterburner, powering the late Tu-144 airliners and the Tu-160 bomber). This engine’s initial derivative, NK-32L-1, adapted for operation with four vectoring nozzles, had a dry thrust of roundabout 110 kN (25,000 lbf) – about 10% more than the Yak-38’s engine trio all together. And the massive engine bore potential for at least 10% more power for the service aircraft.
The overall layout differed considerably from the long and sleek Yak-38: in order to create enough space for the large turbofan stage and its bigger, fixed-configuration air intakes, the fuselage had to be widened behind the cockpit section and the wings' main spar was moved upwards, so that the wings were now shoulder-mounted. The overall arrangement was reminiscent of the successful Hawker Harrier, but differed in some details like the landing gear, which was a classic tricycle design.
Cold air from the NK-32L’s initial turbofan stage was ducted into vectoring nozzles at the forward fuselage flanks, just in front of the aircraft's center of gravity, while the hot exhaust gasses passed through a bifurcated jet pipe through another pair of vectoring nozzles behind the CoG, in an arrangement which was also used in the Yak-38.
Slow speed control was ensured through puffer jet nozzles, fed by bleed air from the engine and placed on both wing tips as well as under the nose and in the aircraft’s tail section.
Teething troubles with the new engine, as well as the new, vectored nozzle arrangement, postponed the Izedeliye 138 prototype’s first flight until March 1986. Work was also slowed down because OKB Yakovlev had been working on the supersonic Yak-41 V/STOL fighter for the Soviet Navy, too. The Soviet Air Force's Frontal Aviation kept interested in the project, though, since they wanted a dedicated attack aircraft, and no complex multi-role fighter.
State acceptance trials lasted until mid 1987, and a total of four prototypes were built (including one for static ground tests). The Yak-138 was found to be easier to handle than the Yak-38, and the single engine made operations and also the handling during flight mode transition much easier and safer.
The prototypes were soon followed by a pre-production batch of 21 aircraft for field trials in frontline units. By then, the NK-32L had been much improved and now offered 137 kN (31,000 lbf) of thrust for short periods, which made it possible to meet all the Frontal Aviations requirements (esp. the call for 2.000 kg ordnance in VTOL mode).
Among its test pilots, the Yak-138 was quite popular and called "Balkon" ("Balcony") because of the good frontal view from the armored cockpit (offering a 17° downwards sight angle).
For frontline service, the aircraft was now equipped with sophisticated avionics, including a Sokol-138 navigation suite with a DISS-7 Doppler radar and a digital computer. A comprehensive ECM suite was installed for self-defence, including SPS-141 and SB-1 active jammers, KDS-23 chaff/flare dispensers built into the ventral pylon and an SPO-10 radar himing and warning system.
In accordance with the Yak-138‘s strike and low-level attack requirements, provisions were made to mount missiles and precision-guided munitions, as well as retaining a nuclear capability in line with other Soviet combat aircraft. An S-17VG-1 optical sight was fitted, as well as a laser rangefinder and marked-target seeker behind a flat, sloped window in the lower nose section.In the upper nose, between the aircraft's two characterisitic pitot booms, a Delta-2NG beam-riding missile guidance system antenna was placed in a small bullet fairing.
By 1989, the initial batch of aircraft had been delivered (receiving the NATO ASCC code 'Flitchbeam') and successfully tested. An order for 42 more aircraft had been placed and a dual training facility with the Soviet Navy at Kaspiysk AB in the Dagestan region (where Soviet Navy Yak-38U trainers were used for transitional training) established , when the disruption of the Soviet Union suddenly stopped the program in 1991 before the Yak-138 could enter production and service on a large scale.
Most of the machines in Frontal Aviation service fell to the Ukraine, where most of the machines had been based. This situation sealed the fate of the promising Yak-138 more or less over night: the now independent Ukraine did not want to keep the exotic type in its arsenal (together with some Yak-38s of the former Soviet Navy, too), and Russia did not want (and could simply not afford) to pay anything for the machines, which had been offered for an unknown sum.
Officially, all Ukrainian Yak-138 were scrapped until 1994, even though rumor has it that one or two airframes had been sold behind the scenes to China. In Russia only five specimen had survived, and since the spares situation was doubtful none could be kept in flying condition. One Yak-138 was eventually handed over to the Ulyanovsk Aircraft Museum, while the rest was either mothballed or scrapped, too. Unfortunately, the sole museum exhibit was lost in 1995 in a fire accident.

The kit and its assembly:
Sixth contribution to the “Soviet” Group Build at whatifmodelers.com in early 2017, on pretty short notice since the GB had been coming to its end. This totally fictional aircraft was inspired CG illustrations that had been roaming the WWW for some time: a hybrid between a Yak-38 (mostly the tail section), mated with an AV-8B Harrier II (cockpit, wings, landing gear). This did not look bad at all, yet a bit weird, with lift engines added in front of the fin. Certainly not conformal with a good CG balance – but I liked the idea of a single-engine Forger. And actually, OKB Yakovlev had been considering this.
So, the basic idea was a Harrier/Yak-38 kitbash. But the more I thought about the concept, the more additional donor parts came into play. One major addition was the nose section from a MiG-27 – with its slanted nose it would offer the pilot an excellent field of view, and the aircraft would, as a front line attack plane like the Harrier, not carry a radar, so the Flogger’s nose shape was perfect.
Therefore, initial ingredients for the Yak-138 were:
- Rear fuselage, wings and tail from a Tsukuda Hobby/Kangnam/Revell Yak-38
- Mid-fuselage with air intakes and front vectoring nozzles from a Matchbox Sea Harrier
- Cockpit from an Academy MiG-27
Work started with the MiG-27 cockpit, which was more or less taken OOB (except for side consoles in the cockpit and different seat), and the Yak-38 the tail section, built in parallel. To my surprise the Forger fuselage was easier to combine with the Harrier than expected, even though the position of the right cuts took multiple measurements until I came up with a proper solution. Since the Harrier is overall shorter than the Yak-38, the latter’s fuselage had to be shortened. I retained the tail cone, the Forger’s vectoring nozzles and the landing gear wells – and a 2cm plug was taken out between them. Instead of the Harrier’s tandem landing gear arrangement with outriggers under the outer wings, this one was to receive a conventional landing gear for optional C/STOL operations with a higher ordnance load, so that the Yak-38 parts were a welcome basis. Once the fuselage’s underside was more or less complete, the upper rest of the Yak-38 fuselage could be cut to size and integrated into the lower half and the Harrier parts.
After the rear end was settled, the MiG-27 cockpit could be mounted to the front end, which was slightly shortened by 2-3mm (since the Flogger’s is markedly longer than the short Harrier nose). In order to change the overall look of the aircraft, I eventually dropped the Harrier intakes and decided to use the Flogger’s boxy air intakes instead. These are considerably smaller than the gaping Harrier holes, and blending the conflicting shapes into each other for a more or less consistent look took several PSR turns. But it worked, better than expected, and it changes the aircraft’s look effectively, so that almost anything Harrier-esque was gone.
Once the fuselage was completed, I realized that I could not use the Yak-38 wings anymore. They are already pretty small, but with the more voluminous Harrier and Flogger parts added to the aircraft, they’d just be too small!
What to do...? I checked the donor bank and – in order to add even more individual flavor – used a pair of double delta wings from a PM Model Su-15! But only the core of them was left after considerable modifications: The inner delta wing sections were cut off, as well as the tip sections and parts of the trailing edge (for a planform similar to the Yak-38’s wings). On the underside, the landing gear openings were filled up and wing tips from the Yak-38, with puffer jet nozzles, transplanted. The inner leading edges had to be re-sculpted, too. The Su-15 wing fences were kept - a welcome, very Soviet design detail.
A lot of work, but I think it paid out because of the individual shape and look of these “new” wings?
As a consequence of the new, bigger wings, the little Yak-38 stabilizers could not be used anymore, either. In order to keep the square wing shape, I used modified stabilizers from an Intech F-16C/D – their trailing edges were clipped, but the bigger span retained. Together with the characteristic OOB Yak-38 fin they work well, and all of the aerodynamic surfaces IMHO blend well into the overall design of the aircraft.
After the hull was complete, work on smaller things could start. Under the fuselage, a GSh-23-2 pod from a MiG-21 was added, as well as pylons from the Tsukuda Yak-38 under the wings and a donor part from the scrap box in ventral position.
The landing gear is a mix, too: the main struts come from the Yak-38, the balloon wheels from the Matchbox Harrier. The front landing gear comes from the Academy MiG-27, including the wheels with mudguards. It was just mounted in a fashion that it now retracts forward.
The Harrier vectoring nozzles were modified, too, the exhaust “grills” replaced by square, simple ducts, scratched from styrene profile and putty. Care was taken that the nozzles would remain moveable in the fuselage flanks – for later hover pictures. The Yak-38’s nozzles were retained, but since they can OOB only be mounted in a single, fixed position, I added a simple pin to each nozzle, together with two holes in the hull, so that positions can now be switched between hover and level flight.
All around the hull, finally some small details like pitots, blade antennae and air scoops were finally added, and the ordnance consists of a pair of unguided 57mm rocket pods and a pair of Kh-23 (AS-7 Kerry) guided missiles – the latter come from the Yak-38 kit, but they are very crude and their tail sections were modified in order to come (slightly) closer to reality.
Painting and markings:
As an aircraft of the Soviet Frontal Aviation in the late Eighties, I settled upon a typical, disruptive four-tone camouflage with blue undersides. Very conventional, but with an exotic VTOL model I thought that a subtle look would be appropriate – and also separate it from the Naval Yak-38 cousin.
Design benchmark is the scheme on a contemporary MiG-21bis from a Soviert Frontal Aviation unit, chosen because of the disruptive pattern. The tones are guesstimates, though, based on various similar aircraft in more or less weathered condition. I settled for:
- Humbrol 195 (Dark Satin Green)
- Humbrol 78 (RAF Interior Green)
- Modelmaster 2005 (Burnt Umber)
- Humbrol 119 (Light Earth)
- Humbrol 115 (Russian Blue) for the undersides
The cockpit was painted in Russian Cockpit Green, opf course. The landing gear and their respective wells in a mix of Aluminum and Khaki Drab (Humbrol 56 & 26), and the wheel discs became bright green (Humbrol 131). Several di-electric panels and antennae were painted in Humbrol 106 (RAF Ocean Grey).
The kit received a thin black ink wash, in order to emphasize the panel lines, and panel post-shading with subtly lighter tones of the basic colors. National markings, codes and emblems come from several aftermarket sheets, mostly from High Decal Line and Begemot.
After some soot stains (grinded graphite) had been added, the kit was sealed with matt acrlyic varnish (Italeri) and the ordnace added.
Messy work, but I am surprised how consistent and normal the resulting aircraft appears? From certain angles, my Yak-138 creation reminds a good deal of the stillborn Hawker P.1154 (no similarity intended, though), the SEPECAT Jaguar or rather exotic Soko J-22 Orao/IAR-93 Vultur fighter bomber. IMHO, there’s also some A-4 Skyhawk style to it, esp. in planview? Anyway, there’s still some good Yak-38 heritage recognizable, and the tactical Frontal Aviation paint scheme suits the aircraft well - looks like a serious mud mover.

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!
Just submitted this photo for an action figure kitbash contest in a Facebook group called "Vintage Action Man and His Foreign Friends." What can I say? Everyone else's submissions looked so nice and creative, I guess I just felt like I had to resort to desperate measures to impress my fellow collectors.
Actually, I really just wanted to win the free vintage Action Man figure they promised to give away to the lucky (hard working) collector whose photo of a kitbashed vintage or vintage style Action Man, G.I. Joe (or the like, such as Spain's Geyper Man or Germany's Action Team) got the most votes.
But why put a suit of armor from a Marx "Noble Knights" set on a vintage style Hasbro G.I. Joe, you may ask? Simple: BECAUSE IT'S A CRAZY HARD THING TO DO! THAT'S WHY!
Therefore, here's a word to the wise, should anyone out there get the bright idea to do the same: Putting Marx armor on a vintage or vintage style G.I. Joe action figure is NOT EASY. You might even say that it's an exercise in sheer frustration! What's more, it's actually just as mind numbingly difficult - or perhaps even harder - to outfit the solid poly plastic sixth scale figure Marx included with each Noble Knights set.
Now mind you, the Marx Noble Knights toys were brilliantly conceived and sculpted overall. Heck! Back in the 1960s, when the venerable old entrepreneurial juggernaut (that once was the Marx Toy company) first unveiled their new series of medieval themed figures, the Noble Knights must have even seemed downright miraculous, to kids and adults alike. As products primarily designed for children go, that is.
What's more, all the armor plates and accessories are highly detailed. And even better than that, even by the standards of today's ultra "high end" figure market, they are just plain beautiful to behold in all their shiny, glittering, metallic poly plastic glory!
As most self respecting vintage Marx toy collectors know good and well, the company utilized many talented sculptors, so the quality often really does appear to be there. And in spades, too! Despite the fact that the Marx corporation itself has long since gone the way of the dodo.
So naturally, most Marx toys tend to look superb on a shelf or in a display case. The problem however, is that the poly plastic many Marx items were cast in (pretty much that same plastic that detergent bottles are made out of) is often so brittle that the tiny connecting tabs on the armor tend to break very, very easily. And once those all important tabs are broken, in many cases, the armor is rendered almost useless.
Even worse, polyethylene plastic doesn't seem to be aging quite as well as its scientific creators once thought it might. Which means that many of the oldest Marx sixth scale figures are now starting to just... break into pieces. Well... not all THAT bad, but quite of few of the original 1965-66 Johnny West and Chief Cherokee action figures are starting to break into any number of pieces, I'm afraid.
Of course, some Marx collectors tend to argue that it's only a problem with those early "caramel" colored figures, but I think we might want to wait and see on that one. I personally own a few Johnny West figures that were produced a decade later (1974, or thereabouts) than the first run caramel colored Johnnys and Chiefs, and they too sometimes break apart -- particularly at or near the oft used joints.
So, bummer. No. MAJOR BUMMER. Especially if you were a kid trying to put the Noble Knights figures together back in the good old days, when even the original poly plastic knights were as yet new! The Noble Knights can even still be a major bummer for voracious kidult toy collectors on a limited budget, who don't necessarily want to go out and be forced to buy half a dozen sets, just to hopefully, finally... get all the armor onto all the different colored figures WITHOUT BREAKING THEM -- thereby rendering most of the sets more or less useless.
Most importantly, the Marx armor sets absolutely do NOT come with replacement parts, just in case you should happen to break something on the first, second, or... even the third for fourth try! So there's not much help for anyone who doesn't manage to outsmart those dumb, brittle, even sometimes ALREADY BROKEN little connection tabs! Nor was there any help for kids who got these lovely (looking) toys back in the much vaunted "good old days" either.
Bummer.
Now, die-hard vintage Marx collectors will of course argue that the stuff originally released back in the late 1960s was made from superior, virgin (non-reground) polyethylene plastic. And although I'm sure that helped the quality of the original items out considerably, I think the vast majority of kids still ended up with broken tabs on their Marx knight figures back in the proverbial day. Which may explain why the company only produced their ultra nifty Noble Knights for just a relatively brief period of time.
Hmm.
'Cause, um... call me a dumb old geeky fan boy collector type... person, but... if the Marx toy company had been making a mint on their Noble Knights series, one would expect that they'd have sold them for quite a lot longer than two (or in some markets, three) short years. So even if their sales initially (or always) were high, it might be relatively safe to assume that they got so many complaints from customers (or requests for replacement parts, rather), it might have seemed like a much better idea to just shut down production of the much vaunted Noble Knights series altogether. Just maybe.
Well, whatever the aforementioned case may in fact be, the 40th Anniversary G.I. Joe figure pictured here is of course wearing much newer production armor cast in Mexico using the original Marx molds. It may be a little more brittle (some would even argue that it's a great deal more brittle) than the now nostalgia infused and glorified original production pieces, but it still works just fine if you handle it with extreme care -- and a whole lot of PATIENCE.
The best part is that I didn't break a single tab on any part of the armor! However... I honestly and very sincerely doubt I could have done it if I'd gotten this set for Christmas back when I was just a kid -- with typical, not yet fully developed childlike dexterity, no less.
So absolutely no disrespect to the Marx Toys legacy, or to nostalgic collectors either, of course, but I've done my homework about that particular toy company and its founder. In fact, Louis Marx had a reputation for producing "high quality toys at a low price." Heck! That was, in fact, the Marx company slogan!
So yes, Marx toys were usually cheaper to produce (making them cheaper for parents to buy) than say, Hasbro's G.I. Joe, but that did not always mean that the quality was quite as good as what Hasbro was offering either.
Yet Marx toys still, to this very day, have a reputation for being practically indestructible. Which is a nice idea, but if you look at the vintage Marx figures that are on offer on eBay alone, many have definitely been beaten to kiddom hell and back. Or "well loved," shall we say!
And sure, as a child, you may not have noticed how much damage you did when you suddenly got the bright idea to chew on poor old Geronimo or Johnny West's foot for a while, but years and years later, when you haul one or both down from the attic, you might see just how much mileage you actually did put on those venerable old childhood friends.
Oh, and just one last thing, if I may. Not that anybody's still reading, of course. Not in this day and age of short attention spans, anyway. But, uh... PSST! The best way to get Marx Noble Knights armor (the highly touted vintage items or the newer Mexican made production pieces) on and off of any suitable sixth scale action figure, is to fill a Tupperware or simply container with hot (almost boiling) water, and immerse the armor pieces for a while. That way, after softening up a bit, the connecting tabs can be very slowly (and extremely carefully) eased open just a tad, with a really small flat head screw driver, or similar tool. It's a very delicate job, so don't say I didn't warn ya!

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Q-6 program was initiated in the mid-1970s when, during the Battle of the Paracel Islands in 1974, the People's Liberation Army Air Force (PLAAF) and People's Liberation Army Naval Air Force (PLANAF) proved incapable of ground support missions. Due to the lack of modern avionics and ground infrastructure to support a modern air war, Chinese aircraft suffered navigation and other logistics problems that severely limited their performance. The first Chinese aircraft did not actually reach the islands until several hours after the battle was over.
In addition to the need to upgrade its logistics capability and infrastructure, China also decided that nothing-in-its-then-aircraft-inventory could fill the requirement for support missions in the South China Sea. Fighters such as the J-5, J-6, J-7, and J-8 lacked a ground attack capability and were hampered by short range. The only Chinese ground attack aircraft atr that time, the Nanchang Q-5 (a MiG-19 derivate with a solid nose, an internal weapon bay and lateral air intakes), was also short ranged and had a relatively low payload. China's bombers such as the Harbin H-5 and Xian H-6 were slow and lacked a sufficient self-defense capability. A new aircraft was therefore seen as desperately needed to fulfill a new naval strike mission in support of the People's Liberation Army Navy (PLAN).
Immediately after the battle, both the PLAAF and PLAN submitted their requirements for a new fighter bomber/ground attack aircraft to the 3rd Ministry of PRC. After extensive research, the 3rd Ministry decided that, based on the Chinese aeronautical industrial capability at the time, it was impossible to develop two separate airplanes at the same time. Instead, a decision was made to develop a single airplane when the prime requirements of the PLAAF and PLAN were similar, even though with different versions tailored to meet the different secondary needs of PLAAF and PLAN.
In June 1976 representatives from various aircraft factories were summoned to Beijing to discuss the project, and were instructed to come up with designs in the shortest possible time. Shenyang Aircraft Factory (later reorganized into Shenyang Aircraft Corporation) was the first to come up with a design, the JH-8 (FB-8), which was essentially a ground attack version of the large, twin-engined J-8II (F-8II) interceptor. Next came the Q-6, a new design from the Nanchang Aircraft Factory. The Xi'an Aircraft Factory (later reorganized into Xi'an Aircraft Industrial Corporation) was the last one to present a design, the Xian JH-7, also a new design.
Initially, the 3rd Ministry favored the JH-8, however because the design of the operational J-8II was still not completed the risk was considered to be too high, so it was eliminated. The projected development of JH-7 was too far out, and so the Q-6 was selected because it was believed to be the one that would be able for service the soonest.
The Q-6's distictive feature was its swing wing arrangement, and the project was China's first venture into this direction. Before the Q-6 program started, however, China had already obtained MiG-23BN and MiG-23MS aircraft from Egypt. A few downed F-111 were also provided to China by North Vietnam. Based on the research effort performed on these aircraft, it was suggested that the variable-sweep wing should be adopted for China's new ground attack aircraft.
The general designer of Nanchang Q-5, and the future academician of the Chinese Academy of Sciences (elected in 1995), Mr. Lu Xiaopeng, was named as the general designer of Q-6. Lu personally visited PLAAF and PLANAF numerous times to obtain their input, which was the base of the Tactical Technological Requirements of the Q-6 he was in charge of, and by February 1979, the general design of the attack aircraft was finalized, based on the initial requirement of the 3rd Ministry.
The original plan was to base the design of Q-6 on the MiG-23BN, the ground attack version of MiG-23. However, both PLAAF and PLAN required a true dogfight capability for self-defense. Due to the need of dogfight capability, a radar was needed, and the ground attack version of the Soviet fighter had no radar. As a result, the plan was changed to base the design on the MiG-23MS instead. But this was not a true solution: Studies revealed that in order to successfully perform the required missions for PLAAF and PLANAF, ground attack radar, as well as terrain-following radar, were needed, too. And for the intended dogfight capability, the RP-22 Sapfir-21 radar (NATO reporting name Jay Bird) of the MiG-23MS lacked the BVR capability.
Facing this technological lack the decision was made to use avionics reverse-engineered from the F-111 to makeup the MiG-23 shortcomings. But as with other technological features adopted for the Q-6, they were proven to be way too ambitious for the Chinese industrial, scientific and technological capability at the time, which resulted in prolonged development.
Problems did not stop, the airframe itself proved to be troublesome, too. Originally the design was based on the MiG-23MS, and was initially thought to be better than the MiG-23BN, because it provided more room in the nosecone to house the radar.
However, the Chinese microelectronic industry could not provide the solid state electronics needed to miniaturize the intended radar, and as a result, the size of the fuselage had theoretically to be increased from the size of the MiG-23 to that of the Su-24 to fit an appropriate radar dish with the technolgy available at that time. Research furthermore revealed that the side-intakes of the MiG-23 design were not sufficient enough to meet the required dogfight capability, so the side-intakes arrangement was changed into a single chin-intake instead, and the Q-6 is claimed to be the first Chinese aircraft to have a chin-mounted intake.
The engine itself was also a problem, since China did not possess a powerful jet fighter engine that would match the intended performance profile of the Q-6. At first there were plans to use 122.4 kN thrust of a WS-6 engine (which was used in the H-6/Tu-16 bomber!), but these were not suited for a fighter and simply too large. To match the targets of an aircraft weight of 14.500 kg, the biggest load of bombs of 4.500 kilograms and a combat radius of 900 km, the Q-6 was finally outfitted with the Wopen WS-9 afterburning turbofan - a license-built Rolls Royce RB.168 Spey Mk. 202 with 91.3 kN of thrust.
Chinese considered the greatest achievement of the Q-6 in its fly-by-wire (FBW) control of the variable-sweep wings, both were the first of its kind in China. The original goal of reverse-engineering the FBW of the F-111 proved to be way too ambitious and had to be abandoned, so a much simpler version was adopted. The triplex analog FBW of the Q-6 was effectively just slightly more advanced than the most rudimentary FBW in that the mechanical servo valves were replaced with electrical servo valves, operated by electronic controllers. But contrary to the most rudimentary FBW, where hydraulic actuators still existed, the hydraulic actuators are replaced by electrical actuators on the Q-6. Anyway, this system proved to be the major obstacle in the hardware development of the Q-6 and it took nine years to complete (1980–1988), under the personal leadership of Mr. Lu Xiaopeng.
In 1988, three prototypes were built: one for static test, one for avionics tests on the ground, and one for the variable sweep wing research. The serial aircraft for PLAAF and PLANAF would have been separate variants, called Q-6A and Q-6B, which are believed to be offered for export now (see below).
Although hailed as a technological breakthrough for the Chinese aviation and providing superior performance to fixed-wing designs (esp. the outdated Q-5), the Chinese system was more than 12% heavier than the simple mechanical-hydraulic controlled variable-sweep wing of the benchmark MiG-23, and the Q-6 avionics were still far from being up-to-date.
Once identified as an indigenous aircraft (the Q-6 was at first deemed to be a variant or straight copy of the MiG-23/27, and therefore premilinarily coded 'Flogger L'), NATO alloted the Code 'Fruitcase' to it, with suffixes for the various export variants (see below).
It was not before 1990 that the aircraft was completed and (theoretically) ready for service – but at that time, technology and military strategy had already changed, and China had been developing the more capable (but much bigger) twin-engined Xian JH-7 fighter bomber for PLAAF and PLANAF. But it would still take some years until the JH-7A would enter service with the PLANAF: in early 2004, and with the PLAAF by the end of the year.
For China, the most important factor which prevented the Q-6 introduction into PLAAF and PLANAF service, was the 'discovery' of stealth features on the battlefield: variable-sweep wing would enlarge the aircraft's radar cross section multiple times and thus making it impossible to survive on the modern battlefield, because it would be much more likely to be detected and shot down.
Anyway, internal politics did not stop China from offering the now completed airframe on the export market as A-6 'Kong Yun' ("Cloud"), as a more capable successor to the Nanchang A-5 (the export version of the MiG-19-based Q-5). From 1992 onwards, several former A-5 users bought the aircraft as A-6 multi-role fighters. It is assumed that these correspond to the Q-6's development lines for PLAAAF an PLANAF.
Current users are the Bangladeshi Air Force (8× A-6B), Myanmar Air Force (20× A-6C), Sri Lanka (11× A-6B) Korean People's Air Force (probably less than 50x A-6A) and the Sudanese Air Force (A total of about 20, 3–11 of them servicable, probably all A-6A).
A-6A ('Fruitcase A'):
The first version and despite being marketed as a "multi-role combat aircraft" a very simple variant with a small radome, probably containing a Type 226 pulse-Doppler radar (a Chinese copy of the GEC-Marconi Skyranger).
A-6B ('Fruitcase B'):
Similar in apperance to the A-6A with a bigger radome. This variant is equipped with a Chinese KLJ-6E pulse-Doppler radar (A Chinese copy of the Italian Pointer-2500 radar, the same as featured on the Chinese Q-5M Fantan attack aircraft), which gives all weather attack capability. These aircraft are also fitted with a HUD, a GPS receiver/inertial navigation system, a 360° radar warning system, a tactical radio navigation system and chaff/flare dispensers on the rear fuselage.
The Sri Lanka aircraft have been seen carrying an external FLIR pod on one of the underfuselage pylons, while the Bangladeshi Air Force aircraft exclusively feature a small fairing under the nose which is believed to contain a LR/MTS, allowing the deployment of PGM.
A-6C ('Fruitcase C'):
Dedicated ground attack variant with a solid, more slender nose and full PGM capability. The nose features a fairing with windows for an ALR-1 laser rangefinder/marked target seeker (LR/MTS) in a small ball turret, and possibly LLLTV/FLIR. This optical system offers day/night attack capability. Like the A-6B, these aircraft feature HUD, GPS, tactical radio and optional flare dispensers.

The kit and its assembly:
This is a whif, but the Nanchang Q-6 was actually developed until 1989 – even though it never entered any service. It was over-ambitious and a dead end, overtaken by technological advances and the fact that Chinese development used to take decades rather than years.
Anyway, the Q-6 actually looked as if someone had glued the nose and air intake of a F-16 onto a MiG-23/27 fuselage - weird, but cool, so why not try this at home?
Like many kitbashing things, what sounds simple turned out to be a bit tricky in detail, even though the surgery was finally easier than expected. The model basis is pretty simple: I took an Academy MiG-27, sawed off the fuselage in the wing roots area (about 1cm, the cockpit section is an extra fuselage section), and did the same with an Italeri F-16 nose section, right behind the cockpit, where the front wheel well ends. The top insert for the single seater was left a bit longer, so that it would overlap with the MiG-23/27 spine.
When you fit these parts together, height is almost perfect, even the wing root/LERX angles match, but there are gaps left on the flanks where the original MiG-27 air intakes would be. These have to be covered, what creates lines reminiscent of the respective area on a MRCA Tornado. Furthermore, the spine behind the cockpit has to be sculpted, too.
Furthermore, the wing root levels of the MiG-23/27 and the F-16 did not match - they have a difference in height of about 4mm on the model, and this was the biggest challenge.
In order to compensate for this problem on my model, any LERX sign was removed from the F-16 nose. Inside of the F-16 section, a column was added that supports the rear upper half of the front fuselage, since the flanks had to go almost completely.
On the outside, the necessary intersections/extensions sculpted new with 2C putty, extending the MiG-23/27 lines forward. The final surface finish was done with NC putty. This major surgery was less complicated than expected - lots of work, though, but feasible.
The new front section with its blended fuselage/LERX area around the cockpit reminds surprisingly much of the MiG-29? As a side note: when you look at CG simulations of this aircraft, this area is a frequent field of trial and error. You find unconclusive, if not impossible designs.
Other changes include a less modern canopy from a MiG-21 (I think it comes from an Academy MiG-21F kit), which was more tricky to fit onto the original F-16 canopy than the LERX stuff. The F-16 canopy looked just too modern for my taste. An old Airfix pilot figure was added, too.
Another new feature is a new jet pipe, a J-79 nozzle from an Italeri Kfir that fits perfectly into the rear fuselage, and the fin. The latter was taken as a leftover part from my recent CF-151A project and comes from a 1:144 scale Tu-22M bomber (Dragon). It's higher, but less deep, and I thought that a slightly different shape and more area would be suitable for an attack aircraft. For the same reason the single, foldable stabilizer fin under the rear fuselage was replaced by two fixed strakes (from the F-16). Small details, but they change the look and make the aircraft appear more simple.
The landing gear was taken from the MiG-27, the front wheel strut had to be slightly shortened due to the reduced wheelbase on the Q-6.
The ordnance was puzzled together – according to current BAF weapons in use. I went for unguided missiles (taken from the Academy MiG-27 donation kit) and some 100kg iron bombs, leftover from a Trumpeter Il-28 bomber kit. These were arranged under the wing roots on improvised tandem MERs.
I did not even try to engrave new panel lines on the new front section - actually, almost the whole upper surface is featureless since it was made with putty. But bot 2C and NC putty are pretty touchy to drilling or engraving (as the rather fruitless attempt to drill open cavities for the two guns proved...), so I decided to just use paint effects.
Painting and markings:
I had been wanting to build a Bangladeshi Air Force aircraft for quite a long time, and the Q-6 was finally a great opportunity. As a ground attack aircraft, the livery was to reflect that role, and among modern BAF aircraft I found C-130 transporters carrying a wrap-around ‘Lizard’/’European One’ scheme, in the traditional tones of FS34102, FS34097 and FS 36081 (Humbrol 117, 149 and 32). Maybe the BAF C-130s are ex USAF aircraft? It seems to be common BAF practice to keep former users' liveries and even bort numbers! Anyway, I find the Lizard cammo on a swing wing aircraft like this rather disturbing, but overall the whole thing looks pretty cool, probably also because of the exotic roundels.
Another option would have been a two-tone green camouflage (seen on BAF An-32 transports) or a three-tone pattern of pale sand, dark brown and dark green with light blue undersides, seen on BAF A-5 fighters. The garish, blue livery of BAF MiG-29s, as well as the blue and grey patterns on BAF F-7 fighters, were ruled out, since they’d rather suggest an air superiority role.
The camouflage pattern is based on USAF A-10 aircraft, and the aircraft’s upper sides were thoroughly weathered with a black ink wash and dry-brushing in lighter shades of the basic tones. After all, my kit is to represent a Q-6 after more than 15 years of service, so that the grey would become much lighter, the dark green get a greyish-blue hue and the light green tone adapt an almost olive drab look. As a result, the aircraft does not look too dark and murky, and the missile ordnance does not stand out too much.
The roundels were improvised – Bangladeshi aircraft kits/decals are rare. AFAIK, only one 1:72 Fujimi MiG-21 offers a BAF markings option, otherwise I could not find anything else, even among aftermarket offerings. Scratching is more fun, though, so “my” markings are actually Pakistani roundels (from a TL Modellbau aftermarket sheet) with red decal discs covering the original white central disc.
The flag on the fin was cut from generic green decal sheet, the red disc was punched out from red decal sheet, just like the roundel additions. Straightforward – and highly effective! Other markings were puzzled together from the scrap box, since the Q-6 never got beyond prototype stage, anything was possible concerning stencils etc.
The bort numbers are guesstimates - typically, BAF (and also PAF) carry a full registration on the tail fin and only a three-digit code on the nose. Squadron emblems are only small and carried either on the nose or the fin, so the model is rather simple in appearance.
The cockpit interior was painted in "Russian Interior Blue-Green" (Testors 2135, a stuff also in use in China, as far as I can tell), the landing gear and its wells were kept in Aluminum (Humbrol 56). The air intake was painted in light grey from the inside, the radome became black.
How it came to be:
This model was initially inspired by a "what if" illustration of a Westland Wyvern in Russian markings (which looked disturbingly realistic...). I have always been fascinated by this brutal construction on the thin line between the prop and jet age, and building one had been a vague plan for a long time. But instead trying to get my hands on a Trumpeter Wyvern in 1:72 I thought: well, if I was going "what if", then I could also build the plane from scratch.
While browsing sources and older Hobby Japan issues, I came across the Sanka and Skyly fighters from Bandai - and things fell together. Why not build a fighter in the post-WWII look of "The Sky Crawlers"?
The construction:
The kit was constructed as a kitbashing, with some scratch elements added. Design benchmark was the Westland Wyvern, but the Skyly J2 also had some influence, as well as various turboprop prototype of the US Navy, esp. the Ryan "Darkshark".
What went into this model:
North American F-86 Sabre (1:72, Hobby Boss):
- Fuselage
- Cockpit interior
- Canopy
Vought F4U-5 Corsair (1:72; Revell):
- Wings
- Landing gear & wheels
- Antennae
Mitsubishi A6M Zero (1:72 , Hasegawa)
- Engine cowl
Gloster Meteor NF.11 (1:72, Xtrakit/Matchbox):
- Vertical fin & horizontal stabilizers
Other smaller donations:(
- McDonnell Douglas F-18A Hornet (1:72, Italieri):
Turboprop spinners (= drop tank halves)
- Martin B-26 Marauder (1x Matchbox, 1x Airfix): Propeller blades
- McDonnell Douglas F-4 Phantom (1:72, Matchbox):
RAF reconnaissance pod
- Grumman F9 Panther: underwing hardpoints
- Kamov Ka-34 "Hokum" (1:72, ESCI): jet exhaust bulges
- WWII pilot figure from an unknown Airfix kit
Building the thing went pretty straightforward. F-86 hull and the Mitsubishi Zero engine cowl were glued together and four coats of NC putty melted the into one. Only a small slit between fuselage and propeller was left open as an air intake for the turboprop engine.
The Corsair wings were taken right out fo the box and could be merged with only minor modifications. On the upper side of the wing/body intersection, bulges for the jet exhaust pipes were added on the fuselage flanks (they were intended to end behind the wings' trailing edge), they consist of parts of the engine pods of a Kamov Ka-34 "Hokum" kit from ESCI. Later, the fuselage was drilled open at their ends and sunk exhaust funnels added - simple polystyrene pipes of 6mm diameter.
A similar pipe was vertically fitted into the fuselage at the plane's CG, for in-flight display (photography purposes).
The cruciform tail comes from an Xtrakit Gloster Meteor NF.11. Originally I planned just to replace the Sabre tail with the complete Meteor tail cone, but the latter turned out to be too slim! As an emergency remedy, I only used the the Meteor's fin and cut away the original jet exhaust of the Sabre - replacing it with a new, fatter tail cone which was built with parts from an RAF F-4 reconnaissance pod from a Matchbox kit (and lots of putty, though). The result is a rather massive tail which reminds of a Mitsubishi Zero's shape, but overall the lines blend well.
The contraprops were built from scratch, and for photography purposes I built tweo specimen: one with propeller blades for static display, and the other one with two clear plastic discs, as if the propellers were running full speed. The base for both is a drop tank from an Italieri F-18 Hornet kit. For the static contraprop, this base was even cut in two and an axis fitted - the propeller is actually fully functional! Its propeller blades come from B-26 Marauder kits and were fitted with reversed pitches, so that the contra-rotating construction would be realistic. Inside of the fuselage, a plastic pipe was used as an adapter for both propellers, making the easily interchangeable.
Even though weapon hardpoints were added, the remained empty - even though my construction looks rather like an attack plane, I wanted to keep a clean air-to-air look and leave a clear view onto the very good Corsair landing gear. The latter was taken 1.1 from the donation kit, just the rear wheel was modified (w/o arresting hook) and a respective compartment cut out of the tail cone.
Livery and markings:
Another subject which was rather difficult. With "whif" planes, you easily end up with prominent markings and camouflage schemes - many such kits bear a Luft'46 look. While this would have been a nice option, I also considered Russian markings (on a pure Aluminum livery or a simple green/light blue cammo scheme). Even painting the whole thing dark blue and adding some white stars would have been a plausible option.
But for a special twist, I wanted to "catch" the retro but subtly colourful spirit of The Sky Crawlers, avoiding a retro-Luftwaffe look. First idea was something that would have looked like an USAF Mustang in late WWII: lower side bare metal, upper sides olive drab and some flashy colours on the spinner, wings and tail. But then I remembered "something different".
The final paint scheme was heavily derived from a rather weird livery which the P-47M "Thunderbolts" from the 63rd fighter squadron, 56th fighter group, 8th Air Force, based in the UK in the final WWII months. Those machines wore a bluish-grey two-tone camouflage on the upper sides, with bare metal undersides. The wings leading edges would be bare metal, too, the engine adorned with a red band and the vertical rudder would be blue. Pretty unique - and AFAIK there's even an airworthy P-47 in this guise around in the USA, flown/kept up by the Confederate Air Force historic flight. This specific machine was actually the benchmark for my paint scheme, because its colours are rather bright.
I more or less sticked to the P-47 paint scheme, just raised the bare metal undersides on the flanks and used brighter colors. These are:
- Testors #1562 "Flat Light Blue"
- Testors #2074 "RLM24 Dunkelblau"
- Testors #1401 "Aluminum Plate" Metallizer
All interior surfaces were painted with RLM02 from Testors, the spinner is plain Testors #1103 "Red". The white stripes were cut from a plain white decal sheet from TL Modellbau, the red insignia are actually French WWII squadron markings in 1:48 scale - also aftermarket pieces from Peddinghaus Decals. Stencelling and bort numbers come from the scrap box.
With the overall exotic shape and cammo scheme, I decided to leave other markings simple and rather neutral – no shark mouth or nose art, even though there would have been plenty of space for such a detail. But I think it would distract too much, and AFAIK no plane in The Sky Crawlers bears such flashy decoration.
The kit was lightly weathered with thinned black paint and some dry painting with shades of grey, plus gun smoke and exhaust fumes with dry-painted black. Everything was sealed under a thin coat of semi-matte varnish.
Final words:
This thing looks disturbingly realistic and plausible, even in its bright livery! While the finish is not perfect (hey, it is scratchbuilt!), the Fafnir (named after a German mythical dragon) really looks like a project from the late 40ies, one of the final high end fighters with a propeller. I am rather surprised how good the result became, and it is exciting to see how such a project evolves step by step, only with a vague idea as a basis. Won't be the last kitbashing!

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Q-6 program was initiated in the mid-1970s when, during the Battle of the Paracel Islands in 1974, the People's Liberation Army Air Force (PLAAF) and People's Liberation Army Naval Air Force (PLANAF) proved incapable of ground support missions. Due to the lack of modern avionics and ground infrastructure to support a modern air war, Chinese aircraft suffered navigation and other logistics problems that severely limited their performance. The first Chinese aircraft did not actually reach the islands until several hours after the battle was over.
In addition to the need to upgrade its logistics capability and infrastructure, China also decided that nothing-in-its-then-aircraft-inventory could fill the requirement for support missions in the South China Sea. Fighters such as the J-5, J-6, J-7, and J-8 lacked a ground attack capability and were hampered by short range. The only Chinese ground attack aircraft atr that time, the Nanchang Q-5 (a MiG-19 derivate with a solid nose, an internal weapon bay and lateral air intakes), was also short ranged and had a relatively low payload. China's bombers such as the Harbin H-5 and Xian H-6 were slow and lacked a sufficient self-defense capability. A new aircraft was therefore seen as desperately needed to fulfill a new naval strike mission in support of the People's Liberation Army Navy (PLAN).
Immediately after the battle, both the PLAAF and PLAN submitted their requirements for a new fighter bomber/ground attack aircraft to the 3rd Ministry of PRC. After extensive research, the 3rd Ministry decided that, based on the Chinese aeronautical industrial capability at the time, it was impossible to develop two separate airplanes at the same time. Instead, a decision was made to develop a single airplane when the prime requirements of the PLAAF and PLAN were similar, even though with different versions tailored to meet the different secondary needs of PLAAF and PLAN.
In June 1976 representatives from various aircraft factories were summoned to Beijing to discuss the project, and were instructed to come up with designs in the shortest possible time. Shenyang Aircraft Factory (later reorganized into Shenyang Aircraft Corporation) was the first to come up with a design, the JH-8 (FB-8), which was essentially a ground attack version of the large, twin-engined J-8II (F-8II) interceptor. Next came the Q-6, a new design from the Nanchang Aircraft Factory. The Xi'an Aircraft Factory (later reorganized into Xi'an Aircraft Industrial Corporation) was the last one to present a design, the Xian JH-7, also a new design.
Initially, the 3rd Ministry favored the JH-8, however because the design of the operational J-8II was still not completed the risk was considered to be too high, so it was eliminated. The projected development of JH-7 was too far out, and so the Q-6 was selected because it was believed to be the one that would be able for service the soonest.
The Q-6's distictive feature was its swing wing arrangement, and the project was China's first venture into this direction. Before the Q-6 program started, however, China had already obtained MiG-23BN and MiG-23MS aircraft from Egypt. A few downed F-111 were also provided to China by North Vietnam. Based on the research effort performed on these aircraft, it was suggested that the variable-sweep wing should be adopted for China's new ground attack aircraft.
The general designer of Nanchang Q-5, and the future academician of the Chinese Academy of Sciences (elected in 1995), Mr. Lu Xiaopeng, was named as the general designer of Q-6. Lu personally visited PLAAF and PLANAF numerous times to obtain their input, which was the base of the Tactical Technological Requirements of the Q-6 he was in charge of, and by February 1979, the general design of the attack aircraft was finalized, based on the initial requirement of the 3rd Ministry.
The original plan was to base the design of Q-6 on the MiG-23BN, the ground attack version of MiG-23. However, both PLAAF and PLAN required a true dogfight capability for self-defense. Due to the need of dogfight capability, a radar was needed, and the ground attack version of the Soviet fighter had no radar. As a result, the plan was changed to base the design on the MiG-23MS instead. But this was not a true solution: Studies revealed that in order to successfully perform the required missions for PLAAF and PLANAF, ground attack radar, as well as terrain-following radar, were needed, too. And for the intended dogfight capability, the RP-22 Sapfir-21 radar (NATO reporting name Jay Bird) of the MiG-23MS lacked the BVR capability.
Facing this technological lack the decision was made to use avionics reverse-engineered from the F-111 to makeup the MiG-23 shortcomings. But as with other technological features adopted for the Q-6, they were proven to be way too ambitious for the Chinese industrial, scientific and technological capability at the time, which resulted in prolonged development.
Problems did not stop, the airframe itself proved to be troublesome, too. Originally the design was based on the MiG-23MS, and was initially thought to be better than the MiG-23BN, because it provided more room in the nosecone to house the radar.
However, the Chinese microelectronic industry could not provide the solid state electronics needed to miniaturize the intended radar, and as a result, the size of the fuselage had theoretically to be increased from the size of the MiG-23 to that of the Su-24 to fit an appropriate radar dish with the technolgy available at that time. Research furthermore revealed that the side-intakes of the MiG-23 design were not sufficient enough to meet the required dogfight capability, so the side-intakes arrangement was changed into a single chin-intake instead, and the Q-6 is claimed to be the first Chinese aircraft to have a chin-mounted intake.
The engine itself was also a problem, since China did not possess a powerful jet fighter engine that would match the intended performance profile of the Q-6. At first there were plans to use 122.4 kN thrust of a WS-6 engine (which was used in the H-6/Tu-16 bomber!), but these were not suited for a fighter and simply too large. To match the targets of an aircraft weight of 14.500 kg, the biggest load of bombs of 4.500 kilograms and a combat radius of 900 km, the Q-6 was finally outfitted with the Wopen WS-9 afterburning turbofan - a license-built Rolls Royce RB.168 Spey Mk. 202 with 91.3 kN of thrust.
Chinese considered the greatest achievement of the Q-6 in its fly-by-wire (FBW) control of the variable-sweep wings, both were the first of its kind in China. The original goal of reverse-engineering the FBW of the F-111 proved to be way too ambitious and had to be abandoned, so a much simpler version was adopted. The triplex analog FBW of the Q-6 was effectively just slightly more advanced than the most rudimentary FBW in that the mechanical servo valves were replaced with electrical servo valves, operated by electronic controllers. But contrary to the most rudimentary FBW, where hydraulic actuators still existed, the hydraulic actuators are replaced by electrical actuators on the Q-6. Anyway, this system proved to be the major obstacle in the hardware development of the Q-6 and it took nine years to complete (1980–1988), under the personal leadership of Mr. Lu Xiaopeng.
In 1988, three prototypes were built: one for static test, one for avionics tests on the ground, and one for the variable sweep wing research. The serial aircraft for PLAAF and PLANAF would have been separate variants, called Q-6A and Q-6B, which are believed to be offered for export now (see below).
Although hailed as a technological breakthrough for the Chinese aviation and providing superior performance to fixed-wing designs (esp. the outdated Q-5), the Chinese system was more than 12% heavier than the simple mechanical-hydraulic controlled variable-sweep wing of the benchmark MiG-23, and the Q-6 avionics were still far from being up-to-date.
Once identified as an indigenous aircraft (the Q-6 was at first deemed to be a variant or straight copy of the MiG-23/27, and therefore premilinarily coded 'Flogger L'), NATO alloted the Code 'Fruitcase' to it, with suffixes for the various export variants (see below).
It was not before 1990 that the aircraft was completed and (theoretically) ready for service – but at that time, technology and military strategy had already changed, and China had been developing the more capable (but much bigger) twin-engined Xian JH-7 fighter bomber for PLAAF and PLANAF. But it would still take some years until the JH-7A would enter service with the PLANAF: in early 2004, and with the PLAAF by the end of the year.
For China, the most important factor which prevented the Q-6 introduction into PLAAF and PLANAF service, was the 'discovery' of stealth features on the battlefield: variable-sweep wing would enlarge the aircraft's radar cross section multiple times and thus making it impossible to survive on the modern battlefield, because it would be much more likely to be detected and shot down.
Anyway, internal politics did not stop China from offering the now completed airframe on the export market as A-6 'Kong Yun' ("Cloud"), as a more capable successor to the Nanchang A-5 (the export version of the MiG-19-based Q-5). From 1992 onwards, several former A-5 users bought the aircraft as A-6 multi-role fighters. It is assumed that these correspond to the Q-6's development lines for PLAAAF an PLANAF.
Current users are the Bangladeshi Air Force (8× A-6B), Myanmar Air Force (20× A-6C), Sri Lanka (11× A-6B) Korean People's Air Force (probably less than 50x A-6A) and the Sudanese Air Force (A total of about 20, 3–11 of them servicable, probably all A-6A).
A-6A ('Fruitcase A'):
The first version and despite being marketed as a "multi-role combat aircraft" a very simple variant with a small radome, probably containing a Type 226 pulse-Doppler radar (a Chinese copy of the GEC-Marconi Skyranger).
A-6B ('Fruitcase B'):
Similar in apperance to the A-6A with a bigger radome. This variant is equipped with a Chinese KLJ-6E pulse-Doppler radar (A Chinese copy of the Italian Pointer-2500 radar, the same as featured on the Chinese Q-5M Fantan attack aircraft), which gives all weather attack capability. These aircraft are also fitted with a HUD, a GPS receiver/inertial navigation system, a 360° radar warning system, a tactical radio navigation system and chaff/flare dispensers on the rear fuselage.
The Sri Lanka aircraft have been seen carrying an external FLIR pod on one of the underfuselage pylons, while the Bangladeshi Air Force aircraft exclusively feature a small fairing under the nose which is believed to contain a LR/MTS, allowing the deployment of PGM.
A-6C ('Fruitcase C'):
Dedicated ground attack variant with a solid, more slender nose and full PGM capability. The nose features a fairing with windows for an ALR-1 laser rangefinder/marked target seeker (LR/MTS) in a small ball turret, and possibly LLLTV/FLIR. This optical system offers day/night attack capability. Like the A-6B, these aircraft feature HUD, GPS, tactical radio and optional flare dispensers.

The kit and its assembly:
This is a whif, but the Nanchang Q-6 was actually developed until 1989 – even though it never entered any service. It was over-ambitious and a dead end, overtaken by technological advances and the fact that Chinese development used to take decades rather than years.
Anyway, the Q-6 actually looked as if someone had glued the nose and air intake of a F-16 onto a MiG-23/27 fuselage - weird, but cool, so why not try this at home?
Like many kitbashing things, what sounds simple turned out to be a bit tricky in detail, even though the surgery was finally easier than expected. The model basis is pretty simple: I took an Academy MiG-27, sawed off the fuselage in the wing roots area (about 1cm, the cockpit section is an extra fuselage section), and did the same with an Italeri F-16 nose section, right behind the cockpit, where the front wheel well ends. The top insert for the single seater was left a bit longer, so that it would overlap with the MiG-23/27 spine.
When you fit these parts together, height is almost perfect, even the wing root/LERX angles match, but there are gaps left on the flanks where the original MiG-27 air intakes would be. These have to be covered, what creates lines reminiscent of the respective area on a MRCA Tornado. Furthermore, the spine behind the cockpit has to be sculpted, too.
Furthermore, the wing root levels of the MiG-23/27 and the F-16 did not match - they have a difference in height of about 4mm on the model, and this was the biggest challenge.
In order to compensate for this problem on my model, any LERX sign was removed from the F-16 nose. Inside of the F-16 section, a column was added that supports the rear upper half of the front fuselage, since the flanks had to go almost completely.
On the outside, the necessary intersections/extensions sculpted new with 2C putty, extending the MiG-23/27 lines forward. The final surface finish was done with NC putty. This major surgery was less complicated than expected - lots of work, though, but feasible.
The new front section with its blended fuselage/LERX area around the cockpit reminds surprisingly much of the MiG-29? As a side note: when you look at CG simulations of this aircraft, this area is a frequent field of trial and error. You find unconclusive, if not impossible designs.
Other changes include a less modern canopy from a MiG-21 (I think it comes from an Academy MiG-21F kit), which was more tricky to fit onto the original F-16 canopy than the LERX stuff. The F-16 canopy looked just too modern for my taste. An old Airfix pilot figure was added, too.
Another new feature is a new jet pipe, a J-79 nozzle from an Italeri Kfir that fits perfectly into the rear fuselage, and the fin. The latter was taken as a leftover part from my recent CF-151A project and comes from a 1:144 scale Tu-22M bomber (Dragon). It's higher, but less deep, and I thought that a slightly different shape and more area would be suitable for an attack aircraft. For the same reason the single, foldable stabilizer fin under the rear fuselage was replaced by two fixed strakes (from the F-16). Small details, but they change the look and make the aircraft appear more simple.
The landing gear was taken from the MiG-27, the front wheel strut had to be slightly shortened due to the reduced wheelbase on the Q-6.
The ordnance was puzzled together – according to current BAF weapons in use. I went for unguided missiles (taken from the Academy MiG-27 donation kit) and some 100kg iron bombs, leftover from a Trumpeter Il-28 bomber kit. These were arranged under the wing roots on improvised tandem MERs.
I did not even try to engrave new panel lines on the new front section - actually, almost the whole upper surface is featureless since it was made with putty. But bot 2C and NC putty are pretty touchy to drilling or engraving (as the rather fruitless attempt to drill open cavities for the two guns proved...), so I decided to just use paint effects.
Painting and markings:
I had been wanting to build a Bangladeshi Air Force aircraft for quite a long time, and the Q-6 was finally a great opportunity. As a ground attack aircraft, the livery was to reflect that role, and among modern BAF aircraft I found C-130 transporters carrying a wrap-around ‘Lizard’/’European One’ scheme, in the traditional tones of FS34102, FS34097 and FS 36081 (Humbrol 117, 149 and 32). Maybe the BAF C-130s are ex USAF aircraft? It seems to be common BAF practice to keep former users' liveries and even bort numbers! Anyway, I find the Lizard cammo on a swing wing aircraft like this rather disturbing, but overall the whole thing looks pretty cool, probably also because of the exotic roundels.
Another option would have been a two-tone green camouflage (seen on BAF An-32 transports) or a three-tone pattern of pale sand, dark brown and dark green with light blue undersides, seen on BAF A-5 fighters. The garish, blue livery of BAF MiG-29s, as well as the blue and grey patterns on BAF F-7 fighters, were ruled out, since they’d rather suggest an air superiority role.
The camouflage pattern is based on USAF A-10 aircraft, and the aircraft’s upper sides were thoroughly weathered with a black ink wash and dry-brushing in lighter shades of the basic tones. After all, my kit is to represent a Q-6 after more than 15 years of service, so that the grey would become much lighter, the dark green get a greyish-blue hue and the light green tone adapt an almost olive drab look. As a result, the aircraft does not look too dark and murky, and the missile ordnance does not stand out too much.
The roundels were improvised – Bangladeshi aircraft kits/decals are rare. AFAIK, only one 1:72 Fujimi MiG-21 offers a BAF markings option, otherwise I could not find anything else, even among aftermarket offerings. Scratching is more fun, though, so “my” markings are actually Pakistani roundels (from a TL Modellbau aftermarket sheet) with red decal discs covering the original white central disc.
The flag on the fin was cut from generic green decal sheet, the red disc was punched out from red decal sheet, just like the roundel additions. Straightforward – and highly effective! Other markings were puzzled together from the scrap box, since the Q-6 never got beyond prototype stage, anything was possible concerning stencils etc.
The bort numbers are guesstimates - typically, BAF (and also PAF) carry a full registration on the tail fin and only a three-digit code on the nose. Squadron emblems are only small and carried either on the nose or the fin, so the model is rather simple in appearance.
The cockpit interior was painted in "Russian Interior Blue-Green" (Testors 2135, a stuff also in use in China, as far as I can tell), the landing gear and its wells were kept in Aluminum (Humbrol 56). The air intake was painted in light grey from the inside, the radome became black.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
The F-112 started life as a privately funded light fighter program by Republic under the handle AP-95 in the mid-1950s, aiming at export markets which were about to replace their 1st generation jet fighters like the F-86 or F-84 and air forces which could not afford or simply want the heavy supersonic fighters under development at that time. In the USA, it was also aimed at the replacement of these Korean War era types in the Air National Guards.
The AP-95 was inspired by both Lockheed's CL-246 (the later F-104 Starfighter) and Northrop's N-156 Light Fighter concept (which eventually developed into the highly successful F-5 fighter family, aiming at the same niches. In size and performance the aircraft fell more or less in between these two design – it was heavier and larger than Northrop’s project, and a less radical alternative to the CL-246. Republic's design team started the development in 1955 and relied heavily on the huge F-105 fighter bomber that had been under development at the time, but the AP-95 was to be a pure interceptor. The basic idea was "to build a relatively small and highly aerodynamic fighter around the same engine that drives the F-100, but focusing on high performance and low cost of maintenance, as well as good field performance."
Actually, the AP-95, called "Thunderdart",was revealed to USAF officials for the first time as a full-sized mock-up in early 1957, and it looked much like a scaled-down F-105. It combined a slender, area-ruled fuselage with highly swept wings and a conventional, low tail.
The nose offered space for a relatively large radar dish. The air intakes were placed in the wing roots, with Ferri-style, forward-swept leading edges that had also been used on the F-105 and other Republic designs like the AP-75 interceptor.
From the F-105 the landing gear concept had been borrowed, too. The long main legs retracted inwards into the wings, leaving only the outer wings free for ordnance loads, but allowed much space in the fuselage for fuel and avionics. The aircraft was to be powered by a Pratt & Whitney J57-P-21 turbojet, with a dry thrust of 10,200 lbf (45 kN) and 16,000 lbf (71 kN) with afterburner.
The basic armament of the AP-95 was an internal 20 mm (.79 in) M61 Vulcan Gatling gun, which had a rate of fire of 6,000 rounds per minute. The cannon, mounted in the lower part of the port fuselage, was fed by a 725-round drum behind the pilot's seat. Additionally, the AP-95 was able to carry up to four AIM-9 Sidewinder AAMs under its wings. Total external payload was 6.000 lb (2.727 kg) on five hardpoints, a centerline pylon under the fuselage was "wet" in order to take a single drop tank. Alternatively, iron bombs or napalm tanks could be carried in a secondary ground support role.
The AP-95 was an attractive design but faced a strong competition, if not opposition. Among USAF officials it was not popular, because it was - despite its basically good performance and low development risks - regarded as an inferior aircraft. It did not reach Mach 2 (what the F-104 promised, despite many other weaknesses), and adding a complex radar system (which would have allowed longer range AAMs like the AIM-7 Sparrow) with an additional operator would further reduce performance.
The aircraft shared a "bad image" fate with the later F-5, which became nevertheless very popular in oversea markets due to its simplicity, versatility and efficacy. On the other side, Europe was already in Lockheed's strong grip, as the F-104G had been selected as NATO's standard fighter bomber - under dubious circumstances, though, but it successfully blocked the market.
Anyway, the AP-95 was nevertheless a capable aircraft which was more cost-effective than the thirsty and short-legged F-104, or the larger F-102 and F-106 which formed the air defense backbone at that era. While the US Air Force did not want another type in its arsenal, it was decided to buy and build the aircraft as a state-of-the-art replacement for the ageing ANG Sabres and Thunderstreaks, with the prospect of delivery of the type to NATO partners all over the world, too.
The original design was quickly approved and the AP-95 prototype made its maiden flight on October 10th, 1960, only equipped with a basic AN/ASG-14T ranging radar. After completing trials and further development with two further YF-112 pre-production aircraft, the Thunderdart was officially introduced as F-112A in March 1962 to the USAF. These production aircraft now featured an AN/APQ-83 radar for night and all-weather interceptions. Additionally, one of the YF-112 was modified in late 1962 to carry a second crew member under a lengthened canopy and with reduced internal fuel - it was planned as a F-112B trainer, but did not find interest since the T-38 already offered supersonic performance at much lower cost, and the Thunderdart's range suffered considerably. The F-112B remained a one-off.
In 1964 the F-112A was also introduced to the US ANG forces and attained some interest from other countries, including Spain, Italy, Turkey, Greece, South Korea and Japan. Most of these foreign countries settled for the Starfighter in the 60ies, and the door for the F-112 was closing: As a result of winning the International Fighter Aircraft competition in 1970, a program aimed at providing effective low cost fighters to American allies, Northrop introduced the second-generation F-5E Tiger II in 1972. This upgrade included more powerful engines, higher fuel capacity, greater wing area and improved leading edge extensions for better turn rate, optional air to air refueling, and improved avionics including air-to-air radar. It became a great success and made the F-112 obsolete, which lacked further development potential and was too limited to its interceptor role to be a versatile option for smaller air forces.
From 1962 until 1965, a total of 145 F-112As were built. Compared with the 1.400 Tiger II versions until 1987 only a very small number, and further orders from the USA did not materialize, even though the Thunderdart showed good flight characteristics.
As a final attempt to improve the Thunderdart's potential, 80 F-112A aircraft were modernized from 1969 on, all of them ANG aircraft. These machines received a more powerful J57-P-20 engine, rated at 18.040lbf (8.200kN) thrust at full afterburner – which finally allowed to break the Mach 2 barrier.
On the avionics side, a new AN/APQ-124 radar was fitted – which still did not allow the guidance of medium range missiles, though, the AIM-9 remained the Thunderdart’s primary weapon. Further enhancements included a more modern firing system and an AAS-15 infrared sensor. These updated aircraft received the designation F-112C, and the MLU phase lasted until 1972. Externally these modified aircraft could easily be identified by the bigger radome and the added IR sensor pod under the nose.
No F-112 was ever used in combat, despite the raging Vietnam War. The original F-112As remained with the USAF, but these were only used for training purposes or as instructional airframes on the ground. These F-112As were quickly phased out during the 70ies, the last one in September 1977. The modernized F-112C soldiered on with several ANG forces until 1985, being replaced by F-4 and F-16 as interceptors and multi-role combat aircraft.

The kit and its assembly:
This is a totally fictional aircraft with no real paradigm. The initial idea was that I wondered if one could not make something from an early MiG-21F with its small diameter air intake, when this would be replaced by a radome?
That the project eventually evolved into a kind of anti-Starfighter came through the wings: there was the problem of placing the air intakes somewhere. To solve that problem I remembered the Tamiya 1:100 F-105 kit, I built one years ago and it’s still available, even though I had to import a NIB kit from Hong Kong for this occasion. Calculations had indicated that the wing size and span would match a 1:72 MiG-21 well, and so the F-112 was born*. The Thunderchief’s air intakes are SO characteristic that anything else than a Republic design was out of question, the rest was spun around this basic idea.
But back to the model itself: the whole thing is a true Frankenstein job, puzzled together from a lot of bits and pieces. The most important ingredients:
● Fuselage from a 1:72 Academy MiG-21F, incl. canopy
● Radome from a 1:72 Hasegawa F-4E
● Wings, pylons and main landing gear from a 1:100 Tamiya F-105
● Stabilizer fins from a 1:72 Revell F-16, shortened
● Main wheels from a 1:72 Hobby Boss F-86F
● Fin from a 1:100 Il-28(!)
● Horizontal stabilizers from a 1:72 Matchbox A-7E w. reduced span
● Front wheel from an 1:72 Italeri A-4M
● Engine nozzle from a 1:72 Matchbox F-104G
● The afterburner inside is actually a sprocket wheel from an 1:72 ESCI M1A1 Abrams
● Cockpit tub and dashboard come from a 1:72 Heller Alpha Jet
● Seat and pilot from Matchbox (unknown origin)
The MiG-21 lost any characteristic detail (blow-in doors, 30mm cannons, slots for wings and stabilizers, even its fin and spine), and the landing gear wells were covered. The F-105 wings were placed slightly lower on the fuselage side. The fin was simply replaced, the tail a bit shortened and the new/bigger nozzle attached. The new nose had almost the same diameter as the original air intake piece from the Academy MiG-21F. For the Corsair II stabilizers, ‘consoles’ were added on the lower rear fuselage, so that they could also be placed in a lower position.
My plan/wish was to make the thing look as little MiG-21ish as possible, and IMHO I succeeded well. Actually, the Thunderdart reminds a LOT of the much bigger F-105, and there is also a lot of F-101 in it, too, despite its ADC livery? You take at least two looks, since proportions are different from the F-105, yet the thing looks VERY familiar… “Could it have been…?”
External loads were limited to just two AIM-9 training rounds with launch rails under the outer pylons, even though all wing pylons were fitted (the Tamiya kit has large slots to hold them, I was too lazy to fill them).
The cannon bulges, the IR sensor as well as some air scoops and antennae were sculpted from simple pieces of sprue or styrene.
Painting and markings:
As an USAF/ADC interceptor, an overall Aircraft Grey (FS 36473, used ModelMaster 1731) was clear from the start – and it’s actually a fine option, as the F-105 as lookalike benchmark was basically only operated in bare metal or SEA camouflage. An ADC aircraft would be deceiving, too, and provoke third looks.
The cockpit interior was painted medium grey, the landing gear wells in interior green and the air intakes in white with red trim.
Anyway, making an ANG aircraft from this base was more tricky. At first I wanted to create an Oklahoma ANG aircraft (had some nice markings for the fin, but they turned out to me too large since they belong to a modern F-16…), but finally settled on a D.C. Air Guard aircraft since I had such fuselage markings from a F-86H at hand.
Basic tone is an overall FS 16473 ADC Grey (Testors 1731), some panels on the upper side and the flanks were highlighted with a slightly lighter grey (FS 16515). The cockpit front area received a flat black anti-glare panel, to which a black trim was added - F-106 style, and this turned out to be VERY characteristic, if not deceiving! Around the rear fuselage some heat marks – reminiscent of the F-100 – were added through metallizer (Steel and Titanium, partly mixed with Humbrol 113, Rust) and some dry-painting. The kit was then lightly weathered through a thin wash with black ink and very light dry-painting with pale grey.
The colorful fin markings were designed by myself – inspired by a 2008 postal stamp from the ‘Flags of our Nation’series. My fin decoration is purely fictional, though, and incorporates the D.C. flag (two red horizontal bars on a white ground, with three red stars above) as well as some iconic cherry blossoms, as these seem to be a local identity symbol? Additionally the fin features on one side the District of Columbia Sign, on the other side the Eastern Air Defence Sector badge. The fin decoration was created on a PC with Corel Draw and printed on Experts' Choice white decal paper with an inkjet printer at 600dpi - even though the touchy decals suffered under the soaking process... A lot of cosmetic correction had to be done by hand/brush, it's far from perfect, just the result of my first large scale self-.made decal experiment. The rest of the markings were puzzled together from the scrap box.
After painting and decals, the kit received an overall coat of semi-gloss Humbrol varnish, since I wanted a slight shine but not a hi-gloss finish. The anti-glare panel was covered with matt varnish - which did not dry up properly, leaving a milky film. Nevertheless, it looks like sun-bleached black paint, so I kept it. Undesired side effect... The radome was painted with gloss varnish, so that three shades of black meet at the Thunderdart's nose.
A major kitbash. The Thunderdart looks unspectacular, but it is IMHO very deceiving. It combines characteristic elements of various Century fighters in shape and color, and it should keep some folks wondering what's actually wrong about it... Sleek aircraft - behold what's in a simple 1st generation MiG-21!
*As a side note: This what-if kit originally bore the designation “F-109”, which was originally allocated to a Bell VTOL aircraft that never made it beyond a mock-up stage. “F-109”, however, has recently found a common use for a fictional fighter which is more or less a crossbreed of an F-104 with F-100 wings and a low tail, so I switched to “F-112” for my own Thunderdart creation. “F-112” had NEVER been used, even though Douglas had used the F-112 code for an F-101 development, but only for internal purposes. Offially it has AFAIK never been used.

Some background:
The "Entwicklung" tank series (= "development"), more commonly known as the E-Series, was a late-World War II attempt by Germany to produce a standardized series of tank designs. There were to be six standard designs in different weight classes, from which several specialized variants were to be developed. This intended to reverse the trend of extremely complex tank designs that had resulted in poor production rates and mechanical unreliability.
The E-series designs were simpler, cheaper to produce and more efficient than their predecessors; however, their design offered only modest improvements in armor and firepower over the designs they were intended to replace, such as the Jagdpanzer 38(t), Panther Ausf.G or Tiger II. However, the resulting high degree of standardization of German armored vehicles would also have made logistics and maintenance easier. Indeed, nearly all of the E-series vehicles — up through and including the E-75 — were intended to use what were essentially the Tiger II's eighty centimeter diameter, steel-rimmed road wheels for their suspension, meant to overlap each other (as on the later production Tiger I-E and Panther designs that also used them), even though in a much simplified fashion.
Focus of initial chassis and combat vehicle development was the E-50/75 Standardpanzer, designed by Adler, both being mostly identical and only differing in armor thickness, overall weight and running gear design to cope with the different weights.
The E-50 Standardpanzer was intended as a medium tank, replacing the Panther and Tiger I battle tanks and the conversions based on these older vehicles. The E-50 hull was to be longer than the Panther, and in fact it was practically identical to the Königstiger (Tiger II) in overall dimensions except for the glacis plate layout. Compared with the earlier designs, however, the amount of drilling and machining involved in producing the Standardpanzer designs was reduced drastically, which would have made them quicker, easier and cheaper to produce, as would the proposed conical spring system, replacing their predecessors' torsion bar system which required a special steel alloy.
The basis development, the combat tank, was to carry the narrow-mantlet 'Schmalturm' turret (designed for the Panther Ausf. F), coupled with a variant of the powerful 88 mm L/71 gun.
In service the vehicle received the inventory ordnance number "SdKfZ. 304" and was officially called "Einheitspanzer 50" (Standard tank), retaining its E-50 abbreviation. The weight of the E-50 vehicle family would fall between 50 and 75 tons. The engine was an improved Maybach HL234 with up to 900 hp output. Maximum speed was supposed to be up to 60 km/h.
The E-75 Standardpanzer (SdKfz. 305), based on the same hull, was intended to be the standard heavy tank and as a replacement of the heavy Tiger II and Jagdtiger tanks. The E-75 would have been built on the same production lines as the E-50 for ease of manufacture, and the two vehicles were to share many components, including the same Maybach HL 234 engine.
As its name indicates, the resulting vehicle would have weighed in at over 75 tons, reducing its speed to around 40 km/h. To offset the increased weight, the bogies were spaced differently from on the E-50, with an extra pair added on each side and eight instead of six wheels plus a slightly wider track, giving the E-75 a slightly improved track to ground contact length.
The basic combat tank version was to be equipped with the same turret and 8.8 cm KwK 43 L/71 as the E-50 battle tank, but along with an optical rangefinder for increased long range accuracy. Anyway, heavier guns (10,5 cm and 12,8 cm caliber) in bigger turrets were under development.
The E-50/E-75 chassis would also become the basis for a family special purpose vehicles like anti-aircraft tanks, assault guns or tank destroyers. One of the earliest developments for the latter class of vehicles was the SdKfz. 191/2, a self-propelled gun carrier for the powerful 12.8 cm KwK L/61 gun, a proven weapon with immense range and firepower, based on the 12.8 cm FlaK 40 anti-aircraft cannon.
The SdKfz. 191/2 was to be much more mobile and lighter than its predecessors, the Jagdtiger and Keiler tank hunters, which had suffered from being overweight and - consequently - underpowered. The new tank hunter was not to exceed 55 tons and offer a field performance similar to the highly effective Jagdpanther, which was only armed with an 88mm cannon, though.
As an appropriate vehicle basis the new E-50 chassis was chosen, but the internal layout was radically modified in order to accept the large and heavy weapon, the crew of six and a decent load of ammunition (which consisted of two parts) in a fully closed combat compartment.
In order to simplify the tank and save weight, the engine section was, together with the gearbox, moved to the hull's front. The complete crew section, including the driver’s position, was placed behind the engine. This was a radically new layout approach, and this form of the standard chassis was called E-50(F) (“F” standing for “Front”; there was also an “M” (= Mitte) for a mid-engine layout, with a separate driver compartment in front of the engine; the standard layout with a rear engine did not receive a dedicated suffix).
The driver’s position behind a long ‘bonnet’ considerably impaired the field of view, and both driver and radio operator, placed on the other side of the hull, had sit in separate "cabins" in front of the casemate-style box main structure. These positions were separated by parts of the engine and the gearbox between them, and accessible from the main combat room.
Despite some inherent weaknesses, this arrangement was regarded as an acceptable price to pay for space and weight savings through only a single major internal fire bulkhead, no need for a long power shaft running all through the hull and an improved crew survivability behind the massive engine against frontal attacks.
The large 12.8 cm cannon was completely covered under a box-shaped superstructure, which had almost vertical side walls. The gun could traverse 7° to each side, elevate 15° and depress -10°. 32 rounds were carried inside of the hull, including armor piercing and explosive shells.
In order to keep the SdKfz. 191/2 within a 60 tons overall weight limit, the vehicle’s front armor was limited to 70mm. This was deemed satisfactory, since the SdKfz. 191/2 was primarily intended for long-range combat only (the weapon had an effective range of 3,500 m (2.2 mi) and more even against heavily armored targets), primarily against heavy Soviet combat tanks and assault guns.
Having learned painful lessons with the Sturmgeschütz IV "Brummbär" and its vulnerability to close range attacks of infantry soldiers, the SdKfz. 191/2 was from the start outfitted with a ball mount for a MG 34 machine gun in the front plate of the superstructure. Another MG 34 on board could be mounted on the commander's cupola for anti-aircraft defense. Smoke dischargers were also available.
A small batch of the SdKfz. 304/2 was built at Deutsche Eisenwerke in mid-1945, to be tested under field conditions. Due to the lack of 12.8cm anti tank guns, around half of the 40 vehicles (production numbers are unclear, since the vehicles were manually converted from initial, unfinished E-50 chassis') were outfitted with the lighter 8,8cm Pak. Both variants were distinguished by "A" and "B" suffixes, respectively, and officially called “Jagdpanzer 12.8cm auf Fahrwerk E-50(F)”, frequently shortened to "Jagdpanzer E-50 (F) A or B".
In service, the relatively agile vehicles were dubbed "Uhlan" (after German light lancer groups in WWI) by their crews, and the more simple name quickly caught on. Another unofficial nickname, based on the separated driver/radio operator compartment and the boxy shape of the tank, was “Beichtstuhl” (“Confessional Box”), but this name was soon forbidden.
The new tank hunters only saw limited use, though, since they suffered from many early production flaws, and general technical reliability was also low. Other weaknesses were soon revealed, too. The SdKfz. 191/2's high casemate design made the vehicle hard to camouflage. With its almost vertical front and side armor, as well as the separate and edgy driver and radio operator compartments, it proved to be very vulnerable, too, so that - on the same chassis - an improved hull (similar to the Jagdpanther, but with the engine in front of the crew section and armed with a new 105 mm cannon) for the newly developed SdKfz 195 hull (a.k.a. "Jagdpanther II") was quickly developed, offering a much improved ballistic protection from any angle.

The kit and its assembly:
This build was spawned from the question: with the German Experimental-Panzer designs becoming available, what would have been an initial solution for the large 12,8cm PaK, and a kind or predecessor of the more effective designs that were to follow (like the Jagdpanther II on E-50/75 basis or the heavy ‘Krokodil’ from the E-100 chassis)? Creations like the Jagdtiger or the Elefant/Ferdinand had failed due to their weight, and roofless self-propelled designs like the Nashorn or the lighter Marder family had also not been very effective designs.
Consequently I tried my luck with a kitbash: the standard E-50 chassis (from a Model Collect combat tank variant), combined with the superstructure of the “Sturer Emil” SPG prototype (Trumpeter kit).
Work started with the lower hull, which was more or less taken OOB – just the upper side was completely re-arranged and the engine roof cut out, together with the attachment ring for the original Schmalturm turret, and transplanted to the front. In this step, the original driver hatches on top of the hull were deleted, too.
On the hull’s gaping rear end I tried to integrate the (originally roofless) weapon compartment from the “Sturer Emil” SPG. The latter comes as a single piece and turned out to be a little too narrow. I could have taken it OOB, but then a small step in the hull’s side walls had to be accepted. So I cut the box structure into pieces and tried to blend them as smoothly into the lower hull’s lines as possible – with the benefit of slightly more angled side walls. The resulting gaps at all four corners were filled with styrene sheet and putty, and the rear wall called for some major adjustments because it has a convex shape with an entry hatch. A bit messy, but the flanking exhaust pipes cover most of the mess.
On the new roof (cut from styrene sheet using a pattern made from adhesive tape and graphite rubbed along the edges), a commander cupola from a Panzer IV and some details like rangefinder optics or air vents were added. Since the interior would not be visible anymore, I only added a primitive console that would hold the OOB cannon bearing and allow slight movement with the barrel in place.
The kit would receive new tracks – vinyl pieces instead of the single styrene pieces from the Model Collect kit. And for a more lively look, the mud guards and side skirts (integral part of the upper hull half) were dented – using a candle flame to warm and warp the material.
Painting and markings:
The rather massive and tall tank was to look simple, yet a bit improvised, so I decided to mimic a primer finish with some thin camouflage paint added on top, so that much of the primer would still shine through.
In an initial step, the hull and still separate parts like the barrel and the wheels received a uniform coat of RAL 3009 Oxidrot – a rich, rust-red tone that comes close to the German primer used on late-war tank hulls. This basic tone was considerably lightened, through dry-brushing and shading with Humbrol 70, 113 and 119 (Brick Red, Rust and Red Brown, respectively), since paint was sparse in Germany in late WWII and colors frequently stretched and thinned with added pigments like white lead, resulting in an almost pinkish tone.
Once dry, the kit received an overall cover with thinned acrylic Sand and Beige (Revell 16 and 314) – almost a custard-colored wash - so that a good amount of the light paint would cling to details and run down the vertical surfaces, leaving an uneven, partly translucent coat on top the red primer that shines through everywhere. This finish was later tailored with brass brush, steel wool and sand paper treatments. No further camouflage (e. g. with Olivgrün) was added, for a simple look.
On top of the basic paint, a dark brown washing was added and the edges further emphasized through dry-brushing with light grey and pale sand tones, plus some acrylic silver. Once the wheels and tracks were fitted into place and the few decals applied, a coat of matt acrylic varnish was added. Finally, dust and dry mud were simulated with mixed pigments, applied with a soft brush onto wet stains of varnish.
An impressive whif tank, and the complex superstructure was quite challenging. Even though it’s a kitbashing, the whole thing looks pretty plausible and “German”, so the original objective was accomplished.

The F-112 started life as a privately funded light fighter program by Republic under the handle AP-95 in the mid-1950s, aiming at export markets which were about to replace their 1st generation jet fighters like the F-86 or F-84 and air forces which could not afford or simply want the heavy supersonic fighters under development at that time. In the USA, it was also aimed at the replacement of these Korean War era types in the Air National Guards.
The AP-95 was inspired by both Lockheed's CL-246 (the later F-104 Starfighter) and Northrop's N-156 Light Fighter concept (which eventually developed into the highly successful F-5 fighter family, aiming at the same niches. In size and performance the aircraft fell more or less in between these two design – it was heavier and larger than Northrop’s project, and a less radical alternative to the CL-246. Republic's design team started the development in 1955 and relied heavily on the huge F-105 fighter bomber that had been under development at the time, but the AP-95 was to be a pure interceptor. The basic idea was "to build a relatively small and highly aerodynamic fighter around the same engine that drives the F-100, but focusing on high performance and low cost of maintenance, as well as good field performance."
Actually, the AP-95, called "Thunderdart",was revealed to USAF officials for the first time as a full-sized mock-up in early 1957, and it looked much like a scaled-down F-105. It combined a slender, area-ruled fuselage with highly swept wings and a conventional, low tail.
The nose offered space for a relatively large radar dish. The air intakes were placed in the wing roots, with Ferri-style, forward-swept leading edges that had also been used on the F-105 and other Republic designs like the AP-75 interceptor.
From the F-105 the landing gear concept had been borrowed, too. The long main legs retracted inwards into the wings, leaving only the outer wings free for ordnance loads, but allowed much space in the fuselage for fuel and avionics. The aircraft was to be powered by a Pratt & Whitney J57-P-21 turbojet, with a dry thrust of 10,200 lbf (45 kN) and 16,000 lbf (71 kN) with afterburner.
The basic armament of the AP-95 was an internal 20 mm (.79 in) M61 Vulcan Gatling gun, which had a rate of fire of 6,000 rounds per minute. The cannon, mounted in the lower part of the port fuselage, was fed by a 725-round drum behind the pilot's seat. Additionally, the AP-95 was able to carry up to four AIM-9 Sidewinder AAMs under its wings. Total external payload was 6.000 lb (2.727 kg) on five hardpoints, a centerline pylon under the fuselage was "wet" in order to take a single drop tank. Alternatively, iron bombs or napalm tanks could be carried in a secondary ground support role.
The AP-95 was an attractive design but faced a strong competition, if not opposition. Among USAF officials it was not popular, because it was - despite its basically good performance and low development risks - regarded as an inferior aircraft. It did not reach Mach 2 (what the F-104 promised, despite many other weaknesses), and adding a complex radar system (which would have allowed longer range AAMs like the AIM-7 Sparrow) with an additional operator would further reduce performance.
The aircraft shared a "bad image" fate with the later F-5, which became nevertheless very popular in oversea markets due to its simplicity, versatility and efficacy. On the other side, Europe was already in Lockheed's strong grip, as the F-104G had been selected as NATO's standard fighter bomber - under dubious circumstances, though, but it successfully blocked the market.
Anyway, the AP-95 was nevertheless a capable aircraft which was more cost-effective than the thirsty and short-legged F-104, or the larger F-102 and F-106 which formed the air defense backbone at that era. While the US Air Force did not want another type in its arsenal, it was decided to buy and build the aircraft as a state-of-the-art replacement for the ageing ANG Sabres and Thunderstreaks, with the prospect of delivery of the type to NATO partners all over the world, too.
The original design was quickly approved and the AP-95 prototype made its maiden flight on October 10th, 1960, only equipped with a basic AN/ASG-14T ranging radar. After completing trials and further development with two further YF-112 pre-production aircraft, the Thunderdart was officially introduced as F-112A in March 1962 to the USAF. These production aircraft now featured an AN/APQ-83 radar for night and all-weather interceptions. Additionally, one of the YF-112 was modified in late 1962 to carry a second crew member under a lengthened canopy and with reduced internal fuel - it was planned as a F-112B trainer, but did not find interest since the T-38 already offered supersonic performance at much lower cost, and the Thunderdart's range suffered considerably. The F-112B remained a one-off.
In 1964 the F-112A was also introduced to the US ANG forces and attained some interest from other countries, including Spain, Italy, Turkey, Greece, South Korea and Japan. Most of these foreign countries settled for the Starfighter in the 60ies, and the door for the F-112 was closing: As a result of winning the International Fighter Aircraft competition in 1970, a program aimed at providing effective low cost fighters to American allies, Northrop introduced the second-generation F-5E Tiger II in 1972. This upgrade included more powerful engines, higher fuel capacity, greater wing area and improved leading edge extensions for better turn rate, optional air to air refueling, and improved avionics including air-to-air radar. It became a great success and made the F-112 obsolete, which lacked further development potential and was too limited to its interceptor role to be a versatile option for smaller air forces.
From 1962 until 1965, a total of 145 F-112As were built. Compared with the 1.400 Tiger II versions until 1987 only a very small number, and further orders from the USA did not materialize, even though the Thunderdart showed good flight characteristics.
As a final attempt to improve the Thunderdart's potential, 80 F-112A aircraft were modernized from 1969 on, all of them ANG aircraft. These machines received a more powerful J57-P-20 engine, rated at 18.040lbf (8.200kN) thrust at full afterburner – which finally allowed to break the Mach 2 barrier.
On the avionics side, a new AN/APQ-124 radar was fitted – which still did not allow the guidance of medium range missiles, though, the AIM-9 remained the Thunderdart’s primary weapon. Further enhancements included a more modern firing system and an AAS-15 infrared sensor. These updated aircraft received the designation F-112C, and the MLU phase lasted until 1972. Externally these modified aircraft could easily be identified by the bigger radome and the added IR sensor pod under the nose.
No F-112 was ever used in combat, despite the raging Vietnam War. The original F-112As remained with the USAF, but these were only used for training purposes or as instructional airframes on the ground. These F-112As were quickly phased out during the 70ies, the last one in September 1977. The modernized F-112C soldiered on with several ANG forces until 1985, being replaced by F-4 and F-16 as interceptors and multi-role combat aircraft.

The kit and its assembly:
This is a totally fictional aircraft with no real paradigm. The initial idea was that I wondered if one could not make something from an early MiG-21F with its small diameter air intake, when this would be replaced by a radome?
That the project eventually evolved into a kind of anti-Starfighter came through the wings: there was the problem of placing the air intakes somewhere. To solve that problem I remembered the Tamiya 1:100 F-105 kit, I built one years ago and it’s still available, even though I had to import a NIB kit from Hong Kong for this occasion. Calculations had indicated that the wing size and span would match a 1:72 MiG-21 well, and so the F-112 was born*. The Thunderchief’s air intakes are SO characteristic that anything else than a Republic design was out of question, the rest was spun around this basic idea.
But back to the model itself: the whole thing is a true Frankenstein job, puzzled together from a lot of bits and pieces. The most important ingredients:
● Fuselage from a 1:72 Academy MiG-21F, incl. canopy
● Radome from a 1:72 Hasegawa F-4E
● Wings, pylons and main landing gear from a 1:100 Tamiya F-105
● Stabilizer fins from a 1:72 Revell F-16, shortened
● Main wheels from a 1:72 Hobby Boss F-86F
● Fin from a 1:100 Il-28(!)
● Horizontal stabilizers from a 1:72 Matchbox A-7E w. reduced span
● Front wheel from an 1:72 Italeri A-4M
● Engine nozzle from a 1:72 Matchbox F-104G
● The afterburner inside is actually a sprocket wheel from an 1:72 ESCI M1A1 Abrams
● Cockpit tub and dashboard come from a 1:72 Heller Alpha Jet
● Seat and pilot from Matchbox (unknown origin)
The MiG-21 lost any characteristic detail (blow-in doors, 30mm cannons, slots for wings and stabilizers, even its fin and spine), and the landing gear wells were covered. The F-105 wings were placed slightly lower on the fuselage side. The fin was simply replaced, the tail a bit shortened and the new/bigger nozzle attached. The new nose had almost the same diameter as the original air intake piece from the Academy MiG-21F. For the Corsair II stabilizers, ‘consoles’ were added on the lower rear fuselage, so that they could also be placed in a lower position.
My plan/wish was to make the thing look as little MiG-21ish as possible, and IMHO I succeeded well. Actually, the Thunderdart reminds a LOT of the much bigger F-105, and there is also a lot of F-101 in it, too, despite its ADC livery? You take at least two looks, since proportions are different from the F-105, yet the thing looks VERY familiar… “Could it have been…?”
External loads were limited to just two AIM-9 training rounds with launch rails under the outer pylons, even though all wing pylons were fitted (the Tamiya kit has large slots to hold them, I was too lazy to fill them).
The cannon bulges, the IR sensor as well as some air scoops and antennae were sculpted from simple pieces of sprue or styrene.
Painting and markings:
As an USAF/ADC interceptor, an overall Aircraft Grey (FS 36473, used ModelMaster 1731) was clear from the start – and it’s actually a fine option, as the F-105 as lookalike benchmark was basically only operated in bare metal or SEA camouflage. An ADC aircraft would be deceiving, too, and provoke third looks.
The cockpit interior was painted medium grey, the landing gear wells in interior green and the air intakes in white with red trim.
Anyway, making an ANG aircraft from this base was more tricky. At first I wanted to create an Oklahoma ANG aircraft (had some nice markings for the fin, but they turned out to me too large since they belong to a modern F-16…), but finally settled on a D.C. Air Guard aircraft since I had such fuselage markings from a F-86H at hand.
Basic tone is an overall FS 16473 ADC Grey (Testors 1731), some panels on the upper side and the flanks were highlighted with a slightly lighter grey (FS 16515). The cockpit front area received a flat black anti-glare panel, to which a black trim was added - F-106 style, and this turned out to be VERY characteristic, if not deceiving! Around the rear fuselage some heat marks – reminiscent of the F-100 – were added through metallizer (Steel and Titanium, partly mixed with Humbrol 113, Rust) and some dry-painting. The kit was then lightly weathered through a thin wash with black ink and very light dry-painting with pale grey.
The colorful fin markings were designed by myself – inspired by a 2008 postal stamp from the ‘Flags of our Nation’series. My fin decoration is purely fictional, though, and incorporates the D.C. flag (two red horizontal bars on a white ground, with three red stars above) as well as some iconic cherry blossoms, as these seem to be a local identity symbol? Additionally the fin features on one side the District of Columbia Sign, on the other side the Eastern Air Defence Sector badge. The fin decoration was created on a PC with Corel Draw and printed on Experts' Choice white decal paper with an inkjet printer at 600dpi - even though the touchy decals suffered under the soaking process... A lot of cosmetic correction had to be done by hand/brush, it's far from perfect, just the result of my first large scale self-.made decal experiment. The rest of the markings were puzzled together from the scrap box.
After painting and decals, the kit received an overall coat of semi-gloss Humbrol varnish, since I wanted a slight shine but not a hi-gloss finish. The anti-glare panel was covered with matt varnish - which did not dry up properly, leaving a milky film. Nevertheless, it looks like sun-bleached black paint, so I kept it. Undesired side effect... The radome was painted with gloss varnish, so that three shades of black meet at the Thunderdart's nose.
A major kitbash. The Thunderdart looks unspectacular, but it is IMHO very deceiving. It combines characteristic elements of various Century fighters in shape and color, and it should keep some folks wondering what's actually wrong about it... Sleek aircraft - behold what's in a simple 1st generation MiG-21!
*As a side note: This what-if kit originally bore the designation “F-109”, which was originally allocated to a Bell VTOL aircraft that never made it beyond a mock-up stage. “F-109”, however, has recently found a common use for a fictional fighter which is more or less a crossbreed of an F-104 with F-100 wings and a low tail, so I switched to “F-112” for my own Thunderdart creation. “F-112” had NEVER been used, even though Douglas had used the F-112 code for an F-101 development, but only for internal purposes. Offially it has AFAIK never been used.

Some background:
The Nakajima Ki-104 was a further development of the Ki-87; the latter was a Japanese high-altitude fighter-interceptor of World War II, a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.
The Ki-87 was one of several designs of various manufacturers developed in response to American B-29 Superfortress raids on the Home Islands. The Ki-87 followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began.
The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the high-performance, tandem-engine Tachikawa Ki-94-I, while the Ki-87 under the lead of Kunihiro Aoki was developed as a fall-back project, using less stringent requirements.
Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945.
The Technical Division of Imperial Army Headquarters made itself felt during the development of the Ki-87 prototype when they insisted upon placing the turbo-supercharger in the rear-fuselage, and from the sixth prototype the Nakajima fighter was to have that arrangement. Construction was further delayed due to problems with the electrical undercarriage and the turbo-supercharger itself. As a consequence, the first Ki-87 prototype was not completed until February 1945; it first flew in April, but only five test flights were completed.
A further variant, the Ki-87-II, powered by a 3,000 hp Nakajima Ha217 (Ha-46) engine and with the turbo-supercharger in the same position as the P-47 Thunderbolt. Due to the long development period of the Ki-87, several major structural changes were made, too, that eventually changed the aircraft so much that it received a new, separate kitai number and became the Ki-104.
Kunihiro Aoki's new design was approved by the Koku Hombu, and an order was placed for one static test airframe, three prototypes, and eighteen pre-production aircraft. Only 2 prototypes were built in the event; the first was equipped with a single 1,895 kW (2,541 hp) Nakajima Ha219 [Ha-44] engine, driving a 4-blade, but the second one received the stronger Nakajima Ha217 (Ha-46) and a 6-blade propeller.
The pre-production machines (Ki-104-I or -Tei) were all produced with Ha217 engines, but featured various four-bladed propeller (-a, -b) designs as well as the new 6-blade propeller (-c). Compared to the prototypes, armament was beefed up from a pair of 20mm Ho-5 and a pair of 30mm Ho-155-I cannons in the wings to four of the new, more compact Ho-155-II cannons (originally designed for the unsuccessful Ki-102 assault aircraft and optimized for wing installation).
All pre-production Ki-104-Is were allocated to an independent IJA Headquarter Flight where they were tested alongside established fighters in the defence of the Tokyo region. Based on this 3rd Independent Flight's unit marking, a completely black tail with the unit's emblem, the Ki-104s were inofficially called Ic '黒の尾'/'Kurono-'o, which literally means "Black Tail".
The first operational Ki-104s reached this unit in spring 1945 and saw limited use against the incoming streams of B-29 bombers (2 unconfirmed downings in the Tokyo region). After these initial contacts that left a serious impression the new type received the USAF code name "Cooper", but the hostilities' soon end however stopped any further work and serial production. No Ki-104 survived the war.

The kit and its assembly:
This whif is the result of many ideas and occasions. First of all, I had a leftover six-blade propeller from a Hasegawa J7W Shinden in stock. Then I recently had an eye on kits of late Japanese high altitude fighters with turbosuperchargers, like the Ki-91-II or the Ki-106. These are available from RS Models, but rare and rather costly. And I wondered how a P-47 might look like without its deep belly? All this was finally thrown into a big idea stew, and the Ki-104 is the home-made hardware result!
As a side note: the Ki-104 was a real IJA project, AFAIK based/related to the Tachikawa Ki-94-I twin-boom/push-pull high altitude fighter, a re-worked, more conventional design. Information is sparese and it never reached any hardware stage and remained a paper project as the Rikugun Kogiken Ki-104; I just "revived" the number for my whif, but maybe the real Ki-104 could have looked like it... ;-)
The kit is a bashing of various parts and pieces:
- Fuselage and wing roots from an Academy P-47-25
- Wings from an Ark Model Supermarine Attacker (ex Novo)
- Tail fin is a modified part of a Matchbox Ju 188 stabilizer
- The stabilizers are outer sections from a Matchbox Douglas F3D Skyknight
- Cowling comes from an ART Model Grumman F8F Bearcat, the engine was scratched
- Propeller from a Hasegawa J7W Shinden
- Main wheels from a Matchbox F6F Hellcat
My choice fell onto the Academy Thunderbolt because it has engraved panel lines, offers the bubble canopy as well as good fit and detail. The belly duct had simply been sliced off, and the opening later faired over with styrene sheet and putty.
The Bearcat cowling was chosen because it had very good fitting width in order to match with the P-47 fuselage, and it turned out to be a very good choice - even though I had to add a dorsal connection, a simple styrene wedge, to create a good profile.
Inside, the engine consists of a reversed Hobby Boss F6F engine, with a fan dummy that covers any view on non-existent interior details... A styrene tube was added, into which a metal axis can be inserted. The latter holds the propeller, so that it can spin with little hindrance.
The Attacker wings were chosen because of their "modern" laminar profile - the Novo kit is horrible, but acceptable for donations. And the risen panel lines and rivets should later do great work during the weathering process... OOB, the Attacker wings had too little span for the big P-47, so I decided to mount the Thunderbolt's OOB wings and cut them at a suitable point: maybe 0.5", just where the large wheel fairings for the main landing gear ends.
The intersection with the Attacker wings is almost perfect in depth and width, relatively little putty work was necessary. I just had to cut out new landing gear well parts.
With the new wing shape, the tail surfaces had to be changed accordingly, with parts from a Matchbox Skyknight and a highly modified piece from a Matchbox Ju 188 stabilizer.
The OOB cockpit and landing gear was retained, I just replaced the main wheels with slightly more delicate alternatives from a Matchbox F6F Hellcat.
Once the basic bodywork was done I added the exhaust arrangement under the fuselage; the outlets are oil cooler parts from a Fw 190A, the air scoop once belonged to a Martin Marauder and the long ducts are actually HO scale roof rails. The oil cooler under the engine comes from a Hobby Boss La-7.
Pretty wild mix, but it works surprisingly well!
Painting and markings:
Even though this was supposed to become a late WWII IJA fighter, I did neither want the stereotype NMF look nor the classic green/grey livery or a respective mottled scheme. What I finally settled upon, though, took a long while to manifest, and it looks ...odd.
I wanted a camouflage scheme, but none of the more exotic real world options was fine for me; there had been fighters with black upper surfaces, bright blue ones, or blue mottle on top of NMF. But all this did not convince me, and I eventually created an experimental scheme. And the paint was supposed to look heavily worn, as if the paint had been applied directly onto the bare metal, without primer, so that it chips and flakes off easily.
The tones were supposed to be suitable for high altitudes, but not the classic IJA colors - nothing even close. eventuelly I came up with an all-around turquoise green (ModelMaster Fulcrum Grey Green) plus a pale grey-green (ModelMaster RAF Dark Slate Grey) as contrast for the upper sides. Sick combination, yes, esp. with the Aluminum shining through, which was applied first as a kind of acrylic primer. The camouflage paint was carefully brushed on top of that, with panel-wise strokes from back to front. Tedious, but effective.
The black tail was applied similarly, it is a free interpretation of real IJA markings; for instance, the 244th Sentai arcraft bore all-red tail sections. Black is an uncommon color, but since I wanted to create fictional squadron markings, too, this was a suitable concept. And it looks cool and mysterious...
The cockpit interior was painted with Aodake Iro (Modelmaster), the section behind the pilot's seat and where the sliding canopy moves on the outside, were painted with IJA Dark Green - just an odd idea. In front of the cockpit a black anti glare panel was added. The landing gear and the respective wells were painted with Steel Metallizer (just to set them apart from the lighter Aluminum all around). The propeller was painted in reddish brown tones, the spinner in Humbrol 160 and the blades in 173.
After this basic painting the kit received a black ink wash, and decals were applied. These were taken from various aftermarket sheets, including generic, white and yellow sheet for the Home Defence markings on wings and fuselage, the white fuselage trim or the yellow ID markings on the wings' leading edges.
As next step the complete kit was carefully wet-sanded, primarily from front to back, so that more of the aluminum primer showed through, the decals (esp. the Hinomaru) were worn out and the camouflage paint on top lost some of its hard edges.
The sanding residues had to be cleaned away thoroughly (with a soft toothbrush and lots of water), and then, repairs, e .g. where the bare plastic came through, as well as extra effects with dry-painted, lighter camouflage tones were done. Final cosmetics also include oil and dirt stains with Tamiya"Smoke", also applied by brush.
Once everything was dry and clean (despite the kit's look), everything was sealed under a coat of varnish - a 3:1 mix of matt and gloss Revell Acrylics.
A complex and lengthy painting process, but I think the effort paid out because the procedure mimicks the structure and look of a worn paint job instead of trying to look like it when you paint a cammo scheme and add metal effects "on top". This works for small chips, but not for the flaked look I had been looking for.
The Ki-104 turned out to be a very conclusive kitbashing - I think that the P-47-with-Attacker-wings-and-new-cowling bears more potential, and I might try it again, e. g. for a naval Thunderbolt development?

Some background:
The Messerschmitt Me 262 Schwalbe or Sturmvogel (English: "Swallow"/ "Storm Bird") was the world's second operational jet-powered fighter aircraft. Design work started before World War II began, but engine problems and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944.
The Me 262 was faster, and more heavily-armed than any Allied fighter, including the British jet-powered Gloster Meteor which entered service in the UK a month earlier than the Me 262. One of the most advanced aviation designs in operational use during World War II, the Me 262 was used in a variety of roles, including light bomber, reconnaissance, and even experimental night fighter versions.
The latter was a variant that was direly needed, and the development of a fast night fighter led to several prototypes and an operational interim version. Several two-seat trainer variants of the Me 262, the Me 262 B-1a, had been adapted through the Umrüst-Bausatz 1 factory refit package as night fighters, complete with on-board FuG 218 Neptun high-VHF band radar, using Hirschgeweih ("stag's antlers") antennae with a set of shorter dipole elements than the Lichtenstein SN-2 had used, as the B-1a/U1 version. Serving with 10 Staffel, Nachtjagdgeschwader 11, near Berlin, these few aircraft (alongside several single-seat examples) accounted for most of the 13 Mosquitoes lost over Berlin in the first three months of 1945.
Anyway, the Me 262 B-1a's deficiencies were clear from the start and in parallel Messerschmitt already worked on a dedicated night fighter variant that would offer a better performance (primarily concerning range and speed) than the converted trainer, which was, nevertheless, rushed into service and gathered valuable information.
Initially, the idea of a night-fighter 262 was developed independently by Messerschmitt as the Me 262B-2. It was to have a longer fuselage accommodating the two crew, internal fuel tanks with the capacity comparable to that of a single-seat variant, and a Berlin radar antenna hidden inside the modified nose cone. However, by the end of 1944 the war situation deteriorated so rapidly that it was realized that an interim solution must be found before the B-2 could reach production status.
Instead of the complex B-2 Messerschmitt also proposed a less ambitious approach which would use as many Me 262 fighter components as possible, primarily the aerodynamic surfaces, the engines and the landing gear. This proposal was accepted by the RLM in September 1944 and became the Me 262 G.
This variant received a completely re-designed and aerodynamically refined fuselage. It was, from the start, tailored to carry the heavy radar equipment, a second crew member as radar operator and navigator and a bigger fuselage tank (the trainers that were converted into night fighters had part of their fuel capacity reduced to make place for the 2nd seat). The result was a slender, streamlined aircraft with a considerably smaller cross section than the Me 262 day fighter/bomber.
The crew was separated into two cabins in front and behind the fuselage main tank. This arrangement also offered enough space for a "Schräge Musik" installation (a pair of guns firing upwards, either two 20mm MG 151/20 or two 30mm MK 108), to allow the night fighter to attack RAF bombers from their belly blind spot.
The main armament was a pair of MK 103 30mm cannons - while this was a reduction of firepower compared to the Me 262 B-1a, the MK 103 was much more accurate, had a longer range and a much higher muzzle velocity (860 m/s (2,822 ft/s) versus 540 m/s (1,800 ft/s) with HE/M), so that targets could be engaged at longer distance with less expenditure of ammunition and further outside of the bombers' defensive fire.
The first operational version, the G-1, was ready for service in December 1944 and exclusively delivered to the NJG 6, based in southern Germany after withdrawal from Romania and regrouping.The G-1 still carried the FuG 218 Neptun radar, still coupled with a high drag Hirschgeweih antenna and with a FuG 350 Zc Naxos radar warning receiver/detector, but the G-1 was still faster than the B-1a and had a longer range on internal fuel than the B-1a with two external 300l drop tanks, which further reduced top speed. Later versions (G-2) were supposed to carry the more modern FuG 240 with a parabolic dish antenna under a more treamlined thimble nose radome, and a single seat long range reconnaissance version (G-3) was also planned, which would carry no guns but an camera array in the radar operators's place.
Anyway, only about 20 Me 262 G-1 were delivered to NJG 6 at all, and probably less than a dozen were operational when Germany surrendered. The G-3 recce variant remained on the drawing board, while two prototypes with radomes for the FuG 240 were under construction and underwent wind tunnel tests.

The kit and its assembly:
Connoisseurs will immediately recognize this kitbash - and the Me 262 G was spawned from the thought that the Japanese Ki-46 was such an elegant aircraft - wouldn't a jet version somehow make sense? So, initially this was supposed to become a Hikoki '46 model, but when I held some Me 262 parts next to the Ki-46's fuselage the idea of a Luftwaffe night fighter was born.
And this actually worked better than expected. This whif is a kitbash of an Airfix Ki-46 fuselage with wings, tail, engines, landing gear and Hirschgeweih from a Revell Me 262 B-1a.
Mating the parts went pretty straightforward, even though I made a mistake when I measured the position of the wing under the fuselage. Somehow it ended up 4-5mm too close to the nose - while the flaw was acceptable I decided to add a 5mm plug behind the pilot cockpit to compensate... And the added length just underlines the elegant Ki-46 lines.
In order to keep the model on its three feet lots of lead beads were hidden in the fuselage, the nose tip and even the front ends of the engine nacelles. Since the Ki-46 fuselage is considerably smaller than the Me 262's I had to fill the wing roots with putty, but that was a rather easy task.
Painting and markings:
I wanted something different from other German night fighters/bombers I had already built, yet a simple livery. Since many German night fighters left the factories in an overall RLM 76 finish I used this as a basis and just added mottles in RLM 75 on the upper surfaces - inspired by a Ta 154 Moskito night fighter prototype.
The cockpits were painted in very dark grey (RLM 66) while the landing gear and the respective wells were painted with RLM 02. Everything very conventional.
The markings were puzzled together - the national markings and stencils come from the Revell Me 262 B-1a sheet while the registration was created from single aftermarket letters, matching a hypothetical aircraft from 4. Staffel, II./NJG 6 in code and colors.
The kit received a light black in wash and some dry-brushing to emphasize panel lines. On the fuselage, however, I painted some panel lines with a pencil, since the Airfix Ki-46 is completely bare of details. Some soot stains around the guns were added with graphite and finally everything sealed under matt acrylic varnish.
A simple kitbashing project, and I am amazed how plausible the Ki-46/Me 262 mix looks, despite the mistake I made with the wing position. I wonder how a Ki-46 III with its streamlined cockpit would look in this case?

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. ^^

Some background:
The Gloster Glaive was basically a modernized and re-engined variant of the successful, British-built Gloster Gladiator (or Gloster SS.37), the RAF’s final biplane fighter to enter service. The Gladiator was not only widely used by the RAF at the dawn of WWII and in almost every theatre of operations, but also by many other nations. Operators included Norway, Belgium, Sweden, Greece, Latvia, Lithuania or Nationalist China, and while the RAF already opted for more modern monoplanes, Gloster saw the opportunity to sell an updated Gladiator to countries which were not as progressive.
Originally designated Gladiator Mk. IV, the machine received many aerodynamic refinements and the motor was changed from a draggy radial to a liquid-cooled inline engine. The latter was the new Rolls Royce Peregrine, a development of the Kestrel. It was, in its original form, a 21-litre (1,300 cu in) liquid-cooled V-12 aero engine ), delivering 885-horsepower (660 kW). The engine was housed under a streamlined cowling, driving a three blade metal propeller, and was coupled with a ventral radiator bath, reminiscent of the Hawker Fury biplane’s arrangement.
Structural improvements included an all-metal monocoque fuselage and stabilizers, as well as new wings and streamlined struts with reduced bracing. The upper wing was enlarged and of all-metal construction, too, while the lower wings were reduced in span and area, almost resulting in a sesquiplane layout. The total wing area was only marginally reduced, though.
The fixed landing gear was retained, but the main wheels were now covered with spats. The pilot still sat in a fully enclosed cockpit, the armament consisted of four machine guns, similar to the Gladiator. But for the Glaive, all Browning machine guns were synchronized and mounted in the fuselage: one pair was placed on top of the cowling, in front of the cockpit. Another pair, much like the Gladiator’s arrangement was placed in the fuselage flanks, below the exhaust outlets.
Compared with the Gladiator, the design changes were so fundamental that Gloster eventually decided to allocate a separate designation – also with a view to the type’s foreign marketing, since a new aircraft appeared more attractive than another mark of a pre-war design. For the type’s virgin flight in late 1938 the name “Glaive” was unveiled to the public, and several smaller European air forces immediately showed interest, including Greece, Croatia, Turkey, Portugal and Egypt.
Greece was one of the initial customers, and the first of a total of 24 aircraft for the Hellenic Air Force was delivered in early 1939, with 24 more on order (which were never delivered, though). The initial batch arrived just in time, since tension had been building between Greece and Italy since 7 April 1939, when Italian troops occupied Albania. On 28 October 1940, Italy issued an ultimatum to Greece, which was promptly rejected. A few hours later, Italian troops launched an invasion of Greece, initiating the Greco-Italian War.
The Hellenic Gloster Glaives were split among three Mirae Dioxeos (Fighter Squadrons): the 21st at Trikala, 22nd at Thessaloniki and 23rd at Larissa. When Italy attacked in October 1940, the British fighter was, together with the PZL 24, the Greeks' only modern type in adequate numbers. However, by late 1940, the Gloster Glaive was already no longer a front-runner despite a powerful powerplant and satisfactory armament. It had no speed advantage over the Fiat Cr.42 nor could it outfly the nimble Italian biplane, and it was much slower than the Macchi MC.200 and the Fiat G.50 it was pitted against. Its agility was the only real advantage against the Italian fighters, whose reliance on the slow firing Breda-SAFAT 12.7mm machine guns proved detrimental.
Anyway, on 5 April 1941, German forces invaded Greece and quickly established air superiority. As the Allied troops retreated, British and Hellenic forces covered them, before flying to Crete during the last week of April. There, the refugee aircraft recorded a few claims over twin-engine aircraft before being evacuated to Egypt during the Battle of Crete.
Overall, the Glaives performed gallantly during the early period of the conflict, holding their own against impossible numerical odds and despite the fact that their main target were enemy bombers which forced them to fight at a disadvantage against enemy fighters. Italian claims of easy superiority over the Albanian front were vastly over-rated and their kill claims even exceeded the total number of operational fighters on the Greek side. Total Greek fighter losses in combat came to 24 a/c with the Greek fighter pilots claiming 64 confirmed kills and 24 probables (about two third bombers).
By April 1941, however, lack of spares and attrition had forced the Hellenic Air Force to merge the surviving seven Glaives with five leftover PZL.24s into one understrength squadron supported by five Gloster Gladiators Mk I & II and the two surviving MB.151s. These fought hopelessly against the Luftwaffe onslaught, and most aircraft were eventually lost on the ground. None of the Hellenic Gloster Glaives survived the conflict.

The kit and its assembly:
The fictional Gloster Glaive started quite simple with the idea of replacing the Gladiator’s radial with an inline engine. But this soon did not appear enough for an update – the Peregrine hardly delivered much more power than the former Mercury, so I considered some structural updates, too. Most of them comprised the replacement of former fabric-covered structures, and this led conceptually to a kitbash with only some Gladiator fuselage and tail parts left.
The basis is (once more) the very nice Matchbox Gloster Gladiator, but it was heavily modified. As an initial step, fuselage, fin and stabilizers (all OOB parts) lost their rib-and-fabric structure, simply sanded away. A minor detail, but it changes the overall look of the aircraft a lot, making it appear much more modern.
The fuselage was left without the OOB radial, and instead a leftover Merlin front end from an Airfix Hurricane (ca. 1cm long, left over from one of my first whif builds ever, a Hurricane with a radial engine!) was added. The lines match pretty well: the side profile looks sleek, if not elegant, but the Gladiator fuselage turned out to be wider than expected. Some major body work/PSR was necessary to integrate the new nose, but the result looks very good.
The liquid-cooled engine necessitated a radiator somewhere on the airframe…! Since I wanted the nose to remain slim and streamlined I eventually placed the radiator bath under the fuselage, much like the arrangement of the Hawker Fury biplane. The radiator itself comes from a late Spitfire (FROG kit).
The exhaust was taken from the Hurricane kit, too, and matching slits dug into the putty nose to take them. The three blade propeller is a mash-up, too: the spinner belongs, IIRC, to an early Spitfire (left over from an AZ Models kit) while the blades came from a damaged Matchbox Brewster Buffalo.
The Gladiator’s fuselage flank machine guns were kept and their “bullet channels” extrapolated along the new cowling, running under the new exhaust pipes. Another pair of machine guns were placed on top of the engine – for these, openings were carved into the upper hull and small fairings (similar to the Browning guns in the flanks) added. This arrangement appeared plausible to me, since the Gladiator’s oil cooler was not necessary anymore and the new lower wings (see below) were not big enough anymore to take the Gladiator’s underwing guns. Four MGs in the fuselage appears massive – but there were other types with such an arrangement, e.g. the Avia B-534 with four guns in the flanks and an inline engine.
The wings are complete replacements: the upper wing comes from a Heller Curtiss SBC4, while the lower wings as well as the spats (on shortened OOB Gladiator struts) come from an ICM Polikarpov I-153. All struts were scratched. Once the lower wings were in place and the relative position of the upper wing clear, the outer struts were carved from 1mm styrene sheet, using the I-153 design as benchmark. These were glued to the lower wing first, and, once totally dry after 24h, the upper wing was simply glued onto the top and the wing position adjusted. This was left to dry another 24h, and as a final step the four struts above the cowling (using the OOB struts, but as single parts and trimmed for proper fit) were placed. This way, a stable connection is guaranteed – and the result is surprisingly sturdy.
Rigging was done with heated sprue material – my personal favorite for this delicate task, and executed before painting the kit started so that the glue could cure and bond well.
Painting and markings:
The reason why this aircraft ended in Greek service is a color photograph of a crashed Hellenic Bloch M.B. 152 (coded ‘D 177’, to be specific). I guess that the picture was post-colored, though, because the aircraft of French origin sports rather weird colors: the picture shows a two-tone scheme in a deep, rather reddish chestnut brown and a light green that almost looks like teal. Unique, to say the least... Underside colors couldn’t be identified with certainty in the picture, but appeared like a pale but not too light blue grey.
Anyway, I assume that these colors are pure fiction and exaggerated Photoshop work, since the few M.B. 152s delivered to Greece carried AFAIK standard French camouflage (in French Khaki, Chestnut Brown and Blue-Grey on the upper surfaces, and a very light blue-grey from below). I’d assume that the contrast between the grey and green tones was not very obvious in the original photograph, so that the artist, not familiar with WWII paint schemes, replaced both colors with the strange teal tone and massively overmodulated the brown.
As weird as it looked, I liked this design and used it as an inspirational benchmark for my Hellenic Glaive build. After all, it’s a fictional aircraft… Upper basic colors are Humbrol 31 (RAF Slate Grey) and 160 (German Camouflage Red Brown), while the undersides became French Dark Blue Grey (ModelMaster Authentics 2105). The result looks rather odd…
Representing a combat-worn aircraft, I applied a thorough black ink wash and did heavier panel shading and dry-brushing on the leading edges, along with some visible touches of aluminum.
The Hellenic roundels come from a TL Modellbau aftermarket sheet. The tactical code was puzzled together from single letters, and the Greek “D” was created from single decal strips. For better contrast I used white decals – most Hellenic aircraft of the time had black codes, but the contrast is much better, and I found evidence that some machines actually carried white codes. The small fin flash is another free interpretation. Not every Hellenic aircraft carried these markings, and instead of painting the whole rudder in Greek colors I just applied a small fin flash. This was created with white and blue decal strips, closely matching the roundels’ colors.
Finally, after some soot stains around the guns and the exhausts, the kit was sealed with matt acrylic varnish.
Modified beyond recognition, perhaps…? The fictional Gloster Glaive looks IMHO good and very modern, just like one of those final biplane designs that were about to be outrun by monoplanes at the brink of WWII.

Some background:
The "Entwicklung" tank series (= "development"), more commonly known as the E-Series, was a late-World War II attempt by Germany to produce a standardized series of tank designs. There were to be six standard designs in different weight classes, from which several specialized variants were to be developed. This intended to reverse the trend of extremely complex tank designs that had resulted in poor production rates and mechanical unreliability.
The E-series designs were simpler, cheaper to produce and more efficient than their predecessors; however, their design offered only modest improvements in armor and firepower over the designs they were intended to replace, such as the Jagdpanzer 38(t), Panther Ausf.G or Tiger II. However, the resulting high degree of standardization of German armored vehicles would also have made logistics and maintenance easier. Indeed, nearly all of the E-series vehicles — up through and including the E-75 — were intended to use what were essentially the Tiger II's eighty centimeter diameter, steel-rimmed road wheels for their suspension, meant to overlap each other (as on the later production Tiger I-E and Panther designs that also used them), even though in a much simplified fashion.
Compared with the earlier designs, the amount of drilling and machining involved in producing the Standardpanzer designs was reduced drastically, which would have made them quicker, easier and cheaper to produce, as would the proposed conical spring system, replacing their predecessors' torsion bar system which required a special steel alloy.
Focus of initial chassis and combat vehicle development was the E-50/75 Standardpanzer, designed by Adler, both being mostly identical and only differing in armor thickness, overall weight and running gear design to cope with the different weights.
There were also lighter chassis variants, though, including the light E-5 and E-10 for armored, tracked reconnaissance vehicles and the E-25. The E-25 designs, in the 25-50 tonnes weight class, were to be the replacements of all Panzer III and Panzer IV based designs, with Alkett, Argus and Adler, with involvement of Porsche. This family would include medium reconnaissance vehicles, medium Jagdpanzer and heavy Waffenträger, using five Tiger II style road wheels per side, combined with "slack-track" design. Track propulsion was switched to a rear drive sprocket, as a consequence of mating the engine and the gearbox into a tail-mounted, single and very compact power pack that made the voluminous and heavy power train through the hull obsolete. This allowed the gun mount to be directly attached to the hull floor, which lowered the overall silhouette, and the gained space offered more room for the crew’s operations as well as for ammunition storage.
The medium tank hunter received high priority and the project was called Jagdpanzer E-25/88 and ran under the inventory ordnance number "SdKfz. 198"; . It was to replace various Panzer IV tank hunters and the light "Hetzer" from 1945 onwards, which all either suffered from insufficient firepower, lack of mobility, or armor. Another tank the E-25/88 would replace was the excellent but complex and expensive Jagdpanther with its 8.8 cm Pak 43/3 or 43/4 L/71 cannon.
The Jagdpanzer E-25/88 was to eradicate all problems of the Panzer IV tank hunter family and combine the benefits from all former types, including the powerful 8.8cm PaK, which could take down any Allied tank around late 1944 at considerably distances. Even though the E-25 tank hunter was initially to be outfitted with the proven 7.5 cm/L70 gun from the Jagdpanzer IV and the Panther battle tank, it was surmised that this armament would not be enough for the enemy's next generation tanks.
Beyond its heavy armament, the new tank hunter was to offer good protection through armor and hull shape alike, as well as high mobility, while keeping overall weight at around 30 tons (the Jagdpanzer IV weighed roundabout 25 tons, while the much bigger Jagdpanther weighed 45 tons) and overall size smaller than the Jagdpanther.
Heavier tank hunters than the E-25/88, based of the new E-50 and E-75 chassis were under development in parallel, but they were all to carry heavier guns, including the 12.8 cm PaK and newly developed 10.5 cm and 13 cm cannons. An E-100 SPG on the drawing board (called "Krokodil") was to carry a 15 cm or even a 17.5 cm anti tank gun.
In late 1944, with the Allied invasion in the West and rising pressure from the East, anti tank and assault SPGs were direly needed and the rejuvenation of the German tank force was sped up in a hurry. As a consequence the Jagdpanzer E-25/88 was prematurely ushered into production before the medium E-25 chassis development had been fully completed.
As a stopgap solution, initial production tanks were outfitted with a Henschel running gear that dated back to the canceled VK20 and VK30 tank program, and these vehicles were later re-designated SdKfz. 198/1 (while the vehicles with the new/standardized running gear became the SdKfz. 198/2). However, its overlapped and interleaved roadwheel-based suspension system (called “Schachtellaufwerk”) was a considerable improvement against the Panzer IV design, even though it was more complex than the final E-25 system. Around 80 vehicles were produced with the Henschel suspension until production was switched to the simplified Alkett suspension based on the unified wheels of the bigger Einheitspanzer types.
The upper hull remained basically the same throughout production, though, and was based on proven principles. To accommodate the heavy-calibre gun, much as on previous unturreted tank destroyers, the glacis plate and sloped hull sides of the Jagdpanzer E-25/88 were extended up into an integral, turretless fixed casemate as part of the main hull itself, providing a relatively roomy interior. The Jagdpanzer E-25/88 had side armour of up to 60 mm, frontal and gun mantlet armour was 80mm. The E-25's engine was a Maybach HL 101 with 550 PS (539 hp, 341 kW), another recognizable improvement in comparison with its frequently underpowered predecessors. Maximum speed was up to 52 km/h (32 mph) on level ground, and the interleafed running gear allowed a smooth ride and high speed even in rough terrain - even though the complex design meant that the wheels could clog up easily with heavy mud or snow.
The gun was mounted in a central "Saukopf" mantlet, similar to the Jagdpanzer IV, and had a limited traverse of 11° to each side, with an elevation of −8° to +15°. 50 rounds for the main gun could be stowed. A single 7.92 mm MG-34 machine gun for frontal defence and against soft ground targets was carried in a ball mount on the right side of the front glacis plate, operated by the wireless operator. Another MG-34 was mounted in a remotely controlled turret on top of the hull, operated by the commander who sat under a cupola with seven periscopes for a good field of view. This machine gun was, in later production tanks, to be replaced by a 30mm MK 108 (actually a compact, belt-fed aircraft machine gun), but this was never carried out since MK 103 production was completely allocated to the Luftwaffe. The driver sat on the left. The gunner had a visual rangefinder and a periscope telescopic sight. The periscope - linked to the gun mount - was under an armored housing on the roof.
In service the vehicle was, due to its crouched silhouette, unofficially called "Dachs" (Badger), a name that was quickly adopted in official circles, too. The first vehicles reached Western front line units along the Rhine in March 1945. They proved to be very successful and popular with its crews, because the tank was agile, easy to handle and less cramped than most of its predecessors. Total production reached 250 vehicles until the end of hostilities, and many of the E-25/88s design features were later incorporated into the post WWII “Jagdpanzer Kanone” for the German Bundeswehr.

The kit and its assembly:
It does not look spectacular, but this compact tank hunter is a major kitbashing, inspired by - but not necessarily an exact model of - the real but unrealized German E-25 Jagdpanzer project.
Things started with a leftover chassis from a Trumpeter "Sturer Emil" SPG with an early interleaf suspension design and a relatively long hull. I wanted to save it and incorporate it into a Heer '46 design, and soon the idea of a Jagdpanzer IV successor was born. Selling it as an E-25 design and incorporating a bigger gun was a logical step.
The build was very pragmatic. The lower hull with the wheel attachments was taken OOB, but it was shortened by 5mm. This was achieved by simply taking away a plug behind the last road wheel and in front of the sprocket wheel, which was moved from the front to the rear end.
While this sounds simple, the attachment points’ different diameters and the need for a sturdy construction (due to the kit’s vinyl tracks) posed quite a challenge. In the wake of this modification, the track’s support wheels were deleted, too, for the E-25’s simplified “slack track” layout. The tracks were shortened accordingly, and mounted/fixed with super glue (as one of the final steps after painting).
The upper hull comes basically from an Armorfast Jagdpanther, after several trials with a Jagdpanzer IV, a Brummbär and even a potentially scratched casemate. The Jagdpanther hull was reduced in height, though, and also slightly shortened, so that the new tank would be more compact than a Jagdpanther and also differ in the silhouette.
In order to change the look even more, the “Saukopf” gun mantlet from a Jagdpanzer IV/70 was implanted (even though with an 8,8cm barrel), as well as the vehicle’s protective shields for the motor deck. Overall hull width was adapted to the Sturer Emil tracks through mudguards.
The machine gun turret was scratched, and some other details changed or added, including some periscopes, a Panzer IV commander cupola and some equipment pieces on the mudguards.
Painting and markings:
This time, I wanted a disruptive scheme for this tank hunter, and adopted a rather simple livery for the E-25/88: a uniform RAL 6003 Olivgrün for the upper hull (appied with a rattle can, plus a hush with RAL 6011 on the upper surfaces), with a dense, irregular pattern of sand/yellow blotches - lighter than the authentic RAL 7028 Dunkelgelb, though (I have used Humbrol 103, Cream).
Wheels and the lower hull flanks (behind the running gear) were painted in RAL 7028 Dunkelgelb (RAL 8000, which comes pretty close, IMHO).
Similar schemes were, for instance, applied to some Ferdinand tank Hunters, operated in Italy and the Eastern Front, but also on Jagdpanthers at the Western front (e. g. in Belgium). The result reminds a bit of a Giraffe, or of the unique British "net" scheme applied to tanks on Malta.
On top of the basic paintwork, a dark brown washing was added and the edges further emphasized through dry-brushing with light grey and pale sand tones, plus some acrylic silver.
Once the wheels and tracks were fitted into place and the few decals applied, a coat of matt acrylic varnish was added. Finally, dust and dry mud were simulated with mixed pigments, applied with a soft brush onto wet stains of varnish.
This E-25 tank hunter model looks pretty conclusive, and at first glance it looks very German, because it incorporates many typical design features. But the more you look the more “unique” it looks, e. g. through the low Schachtellaufwerk, the lowered Jagdpanther upper hull and its combination with the Saukopf gun mantlet from the Jagdpanzer IV. It looks very purposeful, and the paint scheme appears to be very effective, too, blurring the outlines and details well.

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!
I kitbashed the Power Girl figure using the Jiaou doll instead of using the Tbleague body since the Jiaou seems much more curvey than the Tbleague bodies , especially the lower half of the bodies and she filled her suit a whole lot better .

Some background:
The Nakajima Ki-104 was a further development of the Ki-87; the latter was a Japanese high-altitude fighter-interceptor of World War II, a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.
The Ki-87 was one of several designs of various manufacturers developed in response to American B-29 Superfortress raids on the Home Islands. The Ki-87 followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began.
The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the high-performance, tandem-engine Tachikawa Ki-94-I, while the Ki-87 under the lead of Kunihiro Aoki was developed as a fall-back project, using less stringent requirements.
Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945.
The Technical Division of Imperial Army Headquarters made itself felt during the development of the Ki-87 prototype when they insisted upon placing the turbo-supercharger in the rear-fuselage, and from the sixth prototype the Nakajima fighter was to have that arrangement. Construction was further delayed due to problems with the electrical undercarriage and the turbo-supercharger itself. As a consequence, the first Ki-87 prototype was not completed until February 1945; it first flew in April, but only five test flights were completed.
A further variant, the Ki-87-II, powered by a 3,000 hp Nakajima Ha217 (Ha-46) engine and with the turbo-supercharger in the same position as the P-47 Thunderbolt. Due to the long development period of the Ki-87, several major structural changes were made, too, that eventually changed the aircraft so much that it received a new, separate kitai number and became the Ki-104.
Kunihiro Aoki's new design was approved by the Koku Hombu, and an order was placed for one static test airframe, three prototypes, and eighteen pre-production aircraft. Only 2 prototypes were built in the event; the first was equipped with a single 1,895 kW (2,541 hp) Nakajima Ha219 [Ha-44] engine, driving a 4-blade, but the second one received the stronger Nakajima Ha217 (Ha-46) and a 6-blade propeller.
The pre-production machines (Ki-104-I or -Tei) were all produced with Ha217 engines, but featured various four-bladed propeller (-a, -b) designs as well as the new 6-blade propeller (-c). Compared to the prototypes, armament was beefed up from a pair of 20mm Ho-5 and a pair of 30mm Ho-155-I cannons in the wings to four of the new, more compact Ho-155-II cannons (originally designed for the unsuccessful Ki-102 assault aircraft and optimized for wing installation).
All pre-production Ki-104-Is were allocated to an independent IJA Headquarter Flight where they were tested alongside established fighters in the defence of the Tokyo region. Based on this 3rd Independent Flight's unit marking, a completely black tail with the unit's emblem, the Ki-104s were inofficially called Ic '黒の尾'/'Kurono-'o, which literally means "Black Tail".
The first operational Ki-104s reached this unit in spring 1945 and saw limited use against the incoming streams of B-29 bombers (2 unconfirmed downings in the Tokyo region). After these initial contacts that left a serious impression the new type received the USAF code name "Cooper", but the hostilities' soon end however stopped any further work and serial production. No Ki-104 survived the war.

The kit and its assembly:
This whif is the result of many ideas and occasions. First of all, I had a leftover six-blade propeller from a Hasegawa J7W Shinden in stock. Then I recently had an eye on kits of late Japanese high altitude fighters with turbosuperchargers, like the Ki-91-II or the Ki-106. These are available from RS Models, but rare and rather costly. And I wondered how a P-47 might look like without its deep belly? All this was finally thrown into a big idea stew, and the Ki-104 is the home-made hardware result!
As a side note: the Ki-104 was a real IJA project, AFAIK based/related to the Tachikawa Ki-94-I twin-boom/push-pull high altitude fighter, a re-worked, more conventional design. Information is sparese and it never reached any hardware stage and remained a paper project as the Rikugun Kogiken Ki-104; I just "revived" the number for my whif, but maybe the real Ki-104 could have looked like it... ;-)
The kit is a bashing of various parts and pieces:
- Fuselage and wing roots from an Academy P-47-25
- Wings from an Ark Model Supermarine Attacker (ex Novo)
- Tail fin is a modified part of a Matchbox Ju 188 stabilizer
- The stabilizers are outer sections from a Matchbox Douglas F3D Skyknight
- Cowling comes from an ART Model Grumman F8F Bearcat, the engine was scratched
- Propeller from a Hasegawa J7W Shinden
- Main wheels from a Matchbox F6F Hellcat
My choice fell onto the Academy Thunderbolt because it has engraved panel lines, offers the bubble canopy as well as good fit and detail. The belly duct had simply been sliced off, and the opening later faired over with styrene sheet and putty.
The Bearcat cowling was chosen because it had very good fitting width in order to match with the P-47 fuselage, and it turned out to be a very good choice - even though I had to add a dorsal connection, a simple styrene wedge, to create a good profile.
Inside, the engine consists of a reversed Hobby Boss F6F engine, with a fan dummy that covers any view on non-existent interior details... A styrene tube was added, into which a metal axis can be inserted. The latter holds the propeller, so that it can spin with little hindrance.
The Attacker wings were chosen because of their "modern" laminar profile - the Novo kit is horrible, but acceptable for donations. And the risen panel lines and rivets should later do great work during the weathering process... OOB, the Attacker wings had too little span for the big P-47, so I decided to mount the Thunderbolt's OOB wings and cut them at a suitable point: maybe 0.5", just where the large wheel fairings for the main landing gear ends.
The intersection with the Attacker wings is almost perfect in depth and width, relatively little putty work was necessary. I just had to cut out new landing gear well parts.
With the new wing shape, the tail surfaces had to be changed accordingly, with parts from a Matchbox Skyknight and a highly modified piece from a Matchbox Ju 188 stabilizer.
The OOB cockpit and landing gear was retained, I just replaced the main wheels with slightly more delicate alternatives from a Matchbox F6F Hellcat.
Once the basic bodywork was done I added the exhaust arrangement under the fuselage; the outlets are oil cooler parts from a Fw 190A, the air scoop once belonged to a Martin Marauder and the long ducts are actually HO scale roof rails. The oil cooler under the engine comes from a Hobby Boss La-7.
Pretty wild mix, but it works surprisingly well!
Painting and markings:
Even though this was supposed to become a late WWII IJA fighter, I did neither want the stereotype NMF look nor the classic green/grey livery or a respective mottled scheme. What I finally settled upon, though, took a long while to manifest, and it looks ...odd.
I wanted a camouflage scheme, but none of the more exotic real world options was fine for me; there had been fighters with black upper surfaces, bright blue ones, or blue mottle on top of NMF. But all this did not convince me, and I eventually created an experimental scheme. And the paint was supposed to look heavily worn, as if the paint had been applied directly onto the bare metal, without primer, so that it chips and flakes off easily.
The tones were supposed to be suitable for high altitudes, but not the classic IJA colors - nothing even close. eventuelly I came up with an all-around turquoise green (ModelMaster Fulcrum Grey Green) plus a pale grey-green (ModelMaster RAF Dark Slate Grey) as contrast for the upper sides. Sick combination, yes, esp. with the Aluminum shining through, which was applied first as a kind of acrylic primer. The camouflage paint was carefully brushed on top of that, with panel-wise strokes from back to front. Tedious, but effective.
The black tail was applied similarly, it is a free interpretation of real IJA markings; for instance, the 244th Sentai arcraft bore all-red tail sections. Black is an uncommon color, but since I wanted to create fictional squadron markings, too, this was a suitable concept. And it looks cool and mysterious...
The cockpit interior was painted with Aodake Iro (Modelmaster), the section behind the pilot's seat and where the sliding canopy moves on the outside, were painted with IJA Dark Green - just an odd idea. In front of the cockpit a black anti glare panel was added. The landing gear and the respective wells were painted with Steel Metallizer (just to set them apart from the lighter Aluminum all around). The propeller was painted in reddish brown tones, the spinner in Humbrol 160 and the blades in 173.
After this basic painting the kit received a black ink wash, and decals were applied. These were taken from various aftermarket sheets, including generic, white and yellow sheet for the Home Defence markings on wings and fuselage, the white fuselage trim or the yellow ID markings on the wings' leading edges.
As next step the complete kit was carefully wet-sanded, primarily from front to back, so that more of the aluminum primer showed through, the decals (esp. the Hinomaru) were worn out and the camouflage paint on top lost some of its hard edges.
The sanding residues had to be cleaned away thoroughly (with a soft toothbrush and lots of water), and then, repairs, e .g. where the bare plastic came through, as well as extra effects with dry-painted, lighter camouflage tones were done. Final cosmetics also include oil and dirt stains with Tamiya"Smoke", also applied by brush.
Once everything was dry and clean (despite the kit's look), everything was sealed under a coat of varnish - a 3:1 mix of matt and gloss Revell Acrylics.
A complex and lengthy painting process, but I think the effort paid out because the procedure mimicks the structure and look of a worn paint job instead of trying to look like it when you paint a cammo scheme and add metal effects "on top". This works for small chips, but not for the flaked look I had been looking for.
The Ki-104 turned out to be a very conclusive kitbashing - I think that the P-47-with-Attacker-wings-and-new-cowling bears more potential, and I might try it again, e. g. for a naval Thunderbolt development?
I kitbashed the Power Girl figure using the Jiaou doll instead of using the Tbleague body since the Jiaou seems much more curvey than the Tbleague bodies , especially the lower half of the bodies and she filled her suit a whole lot better .

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!

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!
Painting and markings:
I am not certain how ChADI 9 was painted (I assume overall silver), but I wanted for „скорость“ a little more color. Being a child of the Soviet era, red was a settled design element, but I thought that an all-red vehicle might have looked too cheesy. Other colors I considered were orange or white with blue trim, but did not find them to be appropriate for what I was looking. Eventually, I added some Russian Utilitarianism in the form of light grey for the upper hull (Humbrol 166, RAF Light Aircraft Grey), and the red (Humbrol 19) as a dark contrast around the complete air intake as well as the shock cone (somewhat inspired by the Green Monster #15 LSR vehicle), and then extended backwards into a narrowing cheatline along the flanks, which emphasizes the vehicle’s slender hull. For some more contrast between the two basic tones I later added thin white borders between them created with 2mm white decal stripes from TL Modellbau. Around the hull some bright red (Humbrol 238 Red Arrows Red) highlights as warning signs were added.
The vehicle’s afterburner section was painted with Modelmaster Steel Metallizer, the Panther wheels became Aluminum (Revell 99) with a black ink wash. Some black ink was also applied to the jet nozzle, so that the details became more pronounced, and some grinded graphite was used to enhance the burnt metal effect.
Since this would rather be an experimental car built and operated by a high school institute, and also operated in the Soviet Union, flashy sponsor markings would not be appropriate. Therefore I created some fictional marking at home with the help of PC software and printed them by myself. These designs included a fictional logo of the ChADI institute itself (created from a car silhouette drawing) and a logo for the vehicle’s title, “„скорость““. The latter was created from the cyrillic lettering, with some additions like the vehicle’s silhouette.
Unfortunately the production process for the home-made decals did not work properly – when coating the prints with gloss acrylic varnish the printer ink started to dissolve, bleeding magenta, so that the decals would look as if there was a red halo or glow around the otherwise black motifs. Thanks to the use of red in the vehicle’s overall design this flaw is not too apparent, so I stuck with the outcome and applied the decals to the car.
Beyond these basic markings, many stencils were added, including dull red inscriptions from an Italeri MiG-37 “Ferret” kit – finally, I found an expedient use for them! The Soviet flags on the fin came from an 1:144 Tu-144 airliner Braz Decal aftermarket sheet.
Finally, some panel lines were drawn onto the hull with a soft pencil and then the model was sealed with Italeri semi-gloss acrylic varnish. Just the black anti-glare panel in front of the windscreen became matt and the metallic rear section was left in “natural” finish.
Painting and markings:
The Indian Navy theme was already settled, and I wanted to stay close to SPINNERS’ illustration as well as to real world Indian Navy aircraft. SPINNERS’ Hawk carried the typical Sea Harreir scheme in Extra Dark Sea Grey and White, and I found this livery to look a bit too much retro, because I’d place this what-if aircraft in the early 2020s, when the Sea Harriers had already been phased out. A “realistic” livery might have been an overall mid-grey paint scheme (like the land-based Indian Hawk 132s), but I found this to look too boring. As a compromise, I gave the Samudree Baaj a simple two-tone paint scheme, carried by a few late Indian Sea Harriers. It consists of upper surfaces in Dark Sea Grey (Humbrol 164) and undersides in Medium Sea Grey (Modelmaster 2058), with a low waterline. The Modelmaster MSG has – for my taste – a rather bluish hue and appears almost like PRU Blue, but I left it that way.
The decals were puzzled together from variosu sources. the roundels come from a MiG-21F (Begemot), the unit markings and tactical codes from a Model Alliance Sea Harrier sheet, and the stencils are a mix from the Matchbox Hawk 200 and the Italeri T-45.
The kit was sealed with matt acrylic varnish from Italeri.

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?
