Some background:
In the late 1920s, the Aéronautique Militaire (Belgian Air Force) set out to replace its old aircraft. Accordingly, Belgian officers attended the Hendon Air Display where they saw a Fairey Firefly and met Fairey staff. The Firefly toured Belgian air bases in 1930 and met with approval from pilots. This led to a contract for 12 UK-built Firefly II to be followed by a further 33 aircraft built in Belgium.
Fairey already had a number of Belgians in key roles in the company; Ernest Oscar Tips and Marcel Lobelle had joined during the First World War. Tips went to Belgium to set up the subsidiary company. He based the new company near Charleroi. The fighter ace Fernand Jacquet who operated a flying school nearby joined the company in 1931.
Avions Fairey received further orders for Fireflies followed by Fairey Foxes which would be the main aircraft of the Belgian Air Force; being used as a fighter, bomber and training aircraft.
Most of Avions Fairey work was on military contracts. The contact with the Belgian military led to Fairey developing the Fairey Fantôme as a followup to the Firefly for the Belgians. Of the three prototypes, two ended up in Spain (via the USSR) the third as a test aircraft with the RAF.
Another indigenous design of Avions Fairey was the Faune fighter, or better: it's fall-back design. The original design for the Faune started as an advanced (for the era) monoplane under the direction of Ernest Oscar Tips in 1934. He grew concerned that the design would not mature, and ordered a backup biplane design, just to be safe.
Internally called the "Faune-B", the alternative biplane was also a modern design with staggered, gulled upper wings that were directly attached to the fuselage and stabilized by single spars. The single bay wings were of wooden construction, while the fuselage was of mixed steel and duralumin construction, with a fabric covered steering surfaces.
Aerodynamic problems with the favored monoplane design led in 1935 to an end of its development, and further resources were allocated to the biplane. The most significant change of this revised version was the introduction of a retractable landing gear, which necessitated the lower wing main spar to be moved backwards by almost 1' and led to a distinctive wing layout.
In this modified guise the first flight was made in October 1936 with Fernand Jacquet at the controls, powered by an imported Bristol Jupiter engine and outfitted with a wooden, fixed pitch propeller. Armament comprised four 7.5 mm (.295 in) MAC 1934 machine guns with 300 RPG, two synchronized in the upper forward fuselage, and one under each lower wing, mounted in an external nacelle outside the propeller disc.
The Belgian Air Force accepted the fighter and production as Mk. I started in 1938, now powered by a licensed built Bristol Mercury that drove a three blade variable pitch propeller, and a fully enclosed cockpit. Compared with the very similar Gloster Gladiator, which was used by the Aviation Militaire Belge at that time, too, the Faune showed a higher speed and better climb rate, but was not as agile. The field of view for the pilot was poor, especially on the ground, and the narrow and low landing gear made ground handling, esp. on unprepared airfields, hazardous. Furthermore, the landing gear's complicated manual mechanism was prone to failure, and as a consequence the landing gear was frequently kept down so that the aerodynamic bonus was negated.
In late 1939 a total of 42 Avions Fairey Faunes had been built, and in order to compensate for the weaknesses trials were made to incorporate heavier armament in early 1939: the wing-mounted machine guns were on some machines replaced by 20mm Hispano-Suiza HS.404 cannon in deeper fairings and with 40 RPG, and the modified machines were designated Mk. IA. Around 20 machines were converted from service airframes and reached the active squadrons in early 1940. Furthermore, one Faune Mk. I was experimentally outfitted with a streamlined cowling, designated Mk. II, but befor the machine could be tested or even flown, Belgium had been occupied.
With the looming German neighbors, Belgium also ordered Hawker Hurricanes to be built in Belgium. However, on 10 May 1940, the Avions Fairey factory was heavily bombed by the Germans, the company personnel evacuated to France, and then left for England. Their ship was sunk by German bombers outside St Nazaire, though, and eight Fairey staff were killed; the survivors worked for the parent company during the Second World War. None of the Belgian Faunes survived this WWII episode.

The kit and its assembly:
This one was inspired on short notice by a series of side profiles of a fictional British creation called "Bristol Badger", published by whatifmodeler.com's NightHunter with support from Eswube and Darth Panda - very reminiscent of the PZL 24 fighter, but a biplane. A very pretty creation that could rival with the Gloster Gladiator - and seeing the profiles I wondered if a retractable landing gear could be added, in the style of a Grumman F4F or the Curtiss SBC? Hence the idea was born to take this CG creation to the hardware stage.
Another side of the story is that I had been pondering about changing the ugly Curtiss SBC into a single seat fighter. And since the "Badger" would be an equivalent build I eventually decided to combine both ideas.
Legwork turned out that the Bristol Badger actually existed, so it was not the proper name for this creation. Since my designh benchmark was a Belgian aircraft I simply switched the manufacturer to Avions Fairey (see above). ;)
Effectively the Faune is a kitbash of a Heller SBC and a Polikarpov I-15 from ICM - the latter is a noteworthy, small kit because it is full of details, including even an internal frame structure for the cockpit and a highly detailed engine - without any PE parts.
From the SBC the fuselage and the lower wing was taken. The I-15 donated the upper gull wing and its tail - the SBC's was cut away where the observer's station would be, and the diameter of both fuselage sections matches well. The I-15's fabric cover on the tail disappeared under putty. The SBC's canopy was also used , just the observer's rearmost part was cut away and a new spine and fairing sculpted from putty.
Since I wanted a different engine installation (not the streamlined but somewhat ugly solution of the SBC) the SBC fuselage was also cut away in front of the landing gear wells. Bulkheads from styrene sheet were added, and I implanted the nose section and the Bristol Jupiter engine with an open ring cowling from a Matchbox Vickers Wellesley.
Once the wings were in place I implanted the SBC's struts and some wiring was added. The landing gear comes from the SBC, too. The cannons under the wings come from a Hobby Boss Bf 109F.
Painting and markings:
As mentioned above, I used a Belgian Air Force aircraft as design benchmark, and this meant a simple livery in khaki and aluminum dope, similar to Belgian Gloster Gladiators or Fairey Foxes in the late 30ies.
The paint scheme is very simple, I used "French Khaki" from Modelmaster's Authentic enamel range and acrylic Aluminum from Revell. All internal surfaces were painted with RAF Cockpit Green (Modelmaster). The wing struts were painted glossy black, just as on Belgian Foxes or Gladiators of the time.
After a light black ink wash I did some shading with Faded Olive Drab, Humbrol 102 and even some RLM 02, while the Aluminum received some panels in Humbrol 56 and Modelmaster's Aluminum Lacquer. Panel lines were added with a simple, soft pencil.
The decals had to be puzzled together - originally I wanted to use a set for a Belgian Hurricane, but the carreir film turned out to be brittle, so the roundels now come from a generic TL Modellbau sheet, the "Cocotte Bleue" from an anniversary Mirage 5BE, and the codes actually belong to a Chilean D.H. Venom...
Finally, everything was sealed under a mix of 80% flat and 20% gloss acrylic varnish.
In the end, a major kitbash that looks rather simple - but I am actually surprised how well the parts of the I-15 and SBC went together. And the result does not look like the Frankenstein creation this whif kit actually is... ;)

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

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

Some background:
The CAC Sabre, sometimes known as the Avon Sabre or CA-27, was an Australian variant of the North American Aviation F-86F Sabre fighter aircraft. In 1951, Commonwealth Aircraft Corporation obtained a license agreement to build the F-86F Sabre. In a major departure from the North American blueprint, it was decided that the CA-27 would be powered by a license-built version of the Rolls-Royce Avon R.A.7, rather than the General Electric J47. In theory, the Avon was capable of more than double the maximum thrust and double the thrust-to-weight ratio of the US engine. This necessitated a re-design of the fuselage, as the Avon was shorter, wider and lighter than the J47.
To accommodate the Avon, over 60 percent of the fuselage was altered and there was a 25 percent increase in the size of the air intake. Another major revision was in replacing the F-86F's six machine guns with two 30mm ADEN cannon, while other changes were also made to the cockpit and to provide an increased fuel capacity.
The prototype aircraft first flew on 3 August 1953. The production aircrafts' first deliveries to the Royal Australian Air Force began in 1954. The first batch of aircraft were powered by the Avon 20 engine and were designated the Sabre Mk 30. Between 1957 and 1958 this batch had the wing slats removed and were re-designated Sabre Mk 31. These Sabres were supplemented by 20 new-built aircraft. The last batch of aircraft were designated Sabre Mk 32 and used the Avon 26 engine, of which 69 were built up to 1961.
Beyond these land-based versions, an indigenous version for carrier operations had been developed and built in small numbers, too, the Sea Sabre Mk 40 and 41. The roots of this aircraft, which was rather a prestigious idea than a sensible project, could be traced back to the immediate post WWII era. A review by the Australian Government's Defence Committee recommended that the post-war forces of the RAN be structured around a Task Force incorporating multiple aircraft carriers. Initial plans were for three carriers, with two active and a third in reserve, although funding cuts led to the purchase of only two carriers in June 1947: Majestic and sister ship HMS Terrible, for the combined cost of AU£2.75 million, plus stores, fuel, and ammunition. As Terrible was the closer of the two ships to completion, she was finished without modification, and was commissioned into the RAN on 16 December 1948 as HMAS Sydney. Work progressed on Majestic at a slower rate, as she was upgraded with the latest technology and equipment. To cover Majestic's absence, the Colossus-class carrier HMS Vengeance was loaned to the RAN from 13 November 1952 until 12 August 1955.
Labour difficulties, late delivery of equipment, additional requirements for Australian operations, and the prioritization of merchant ships over naval construction delayed the completion of Majestic. Incorporation of new systems and enhancements caused the cost of the RAN carrier acquisition program to increase to AU£8.3 million. Construction and fitting out did not finish until October 1955. As the carrier neared completion, a commissioning crew was formed in Australia and first used to return Vengeance to the United Kingdom.
The completed carrier was commissioned into the RAN as HMAS Majestic on 26 October 1955, but only two days later, the ship was renamed Melbourne and recommissioned.
In the meantime, the rather political decision had been made to equip Melbourne with an indigenous jet-powered aircraft, replacing the piston-driven Hawker Fury that had been successfully operated from HMAS Sydney and HMAS Vengeance, so that the "new jet age" was even more recognizable. The choice fell on the CAC Sabre, certainly inspired by North American's successful contemporary development of the navalized FJ-2 Fury from the land-based F-86 Sabre. The CAC 27 was already a proven design, and with its more powerful Avon engine it even offered a better suitability for carrier operations than the FJ-2 with its rather weak J47 engine.
Work on this project, which was initially simply designated Sabre Mk 40, started in 1954, just when the first CAC 27's were delivered to operative RAAF units. While the navalized Avon Sabre differed outwardly only little from its land-based brethren, many details were changed and locally developed. Therefore, there was also, beyond the general outlines, little in common with the North American FJ-2 an -3 Fury.
Externally, a completely new wing with a folding mechanism was fitted. It was based on the F-86's so-called "6-3" wing, with a leading edge that was extended 6 inches at the root and 3 inches at the tip. This modification enhanced maneuverability at the expense of a small increase in landing speed due to deletion of the leading edge slats, a detail that was later introduced on the Sabre Mk 31, too. As a side benefit, the new wing leading edges without the slat mechanisms held extra fuel. However, the Mk 40's wing was different as camber was applied to the underside of the leading edge to improve low-speed handling for carrier operations. The wings were provided with four stations outboard of the landing gear wells for up to 1000 lb external loads on the inboard stations and 500 lb on the outboard stations.
Slightly larger stabilizers were fitted and the landing gear was strengthened, including a longer front wheel strut. The latter necessitated an enlarged front wheel well, so that the front leg’s attachment point had to be moved forward. A ventral launch cable hook was added under the wing roots and an external massive arrester hook under the rear fuselage.
Internally, systems were protected against salt and humidity and a Rolls-Royce Avon 211 turbojet was fitted, a downrated variant of the already navalized Avon 208 from the British DH Sea Vixen, but adapted to the different CAC 27 airframe and delivering 8.000 lbf (35.5 kN) thrust – slightly more than the engines of the land-based CAC Sabres, but also without an afterburner.
A single Mk 40 prototype was built from a new CAC 27 airframe taken directly from the production line in early 1955 and made its maiden flight on August 20th of the same year. In order to reflect its naval nature and its ancestry, this new CAC 27 variant was officially christened “Sea Sabre”.
Even though the modified machine handled well, and the new, cambered wing proved to be effective, many minor technical flaws were discovered and delayed the aircraft's development until 1957. These included the wing folding mechanism and the respective fuel plumbing connections, the landing gear, which had to be beefed up even more for hard carrier landings and the airframe’s structural strength for catapult launches, esp. around the ventral launch hook.
In the meantime, work on the land-based CAC 27 progressed in parallel, too, and innovations that led to the Mk 31 and 32 were also incorporated into the naval Mk 40, leading to the Sea Sabre Mk 41, which became the effective production aircraft. These updates included, among others, a detachable (but fixed) refueling probe under the starboard wing, two more pylons for light loads located under the wing roots and the capability to carry and deploy IR-guided AIM-9 Sidewinder air-to-air missiles, what significantly increased the Mk 41's efficiency as day fighter. With all these constant changes it took until April 1958 that the Sabre Mk 41, after a second prototype had been directly built to the new standard, was finally approved and cleared for production. Upon delivery, the RAN Sea Sabres carried a standard NATO paint scheme with Extra Dark Sea Grey upper surfaces and Sky undersides.
In the meantime, the political enthusiasm concerning the Australian carrier fleet had waned, so that only twenty-two aircraft were ordered. The reason behind this decision was that Australia’s carrier fleet and its capacity had become severely reduced: Following the first decommissioning of HMAS Sydney in 1958, Melbourne became the only aircraft carrier in Australian service, and she was unavailable to provide air cover for the RAN for up to four months in every year; this time was required for refits, refueling, personnel leave, and non-carrier duties, such as the transportation of troops or aircraft. Although one of the largest ships to serve in the RAN, Melbourne was one of the smallest carriers to operate in the post-World War II period, so that its contribution to military actions was rather limited. To make matters worse, a decision was made in 1959 to restrict Melbourne's role to helicopter operations only, rendering any carrier-based aircraft in Australian service obsolete. However, this decision was reversed shortly before its planned 1963 implementation, but Australia’s fleet of carrier-borne fixed-wing aircraft would not grow to proportions envisioned 10 years ago.
Nevertheless, on 10 November 1964, an AU£212 million increase in defense spending included the purchase of new aircraft for Melbourne. The RAN planned to acquire 14 Grumman S-2E Tracker anti-submarine aircraft and to modernize Melbourne to operate these. The acquisition of 18 new fighter-bombers was suggested (either Sea Sabre Mk 41s or the American Douglas A-4 Skyhawk), too, but these were dropped from the initial plan. A separate proposal to order 10 A-4G Skyhawks, a variant of the Skyhawk designed specifically for the RAN and optimized for air defense, was approved in 1965, but the new aircraft did not fly from Melbourne until the conclusion of her refit in 1969. This move, however, precluded the production of any new and further Sea Sabre.
At that time, the RAN Sea Sabres received a new livery in US Navy style, with upper surfaces in Light Gull Gray with white undersides. The CAC Sea Sabres remained the main day fighter and attack aircraft for the RAN, after the vintage Sea Furies had been retired in 1962. The other contemporary RAN fighter type in service, the Sea Venom FAW.53 all-weather fighter that had replaced the Furies, already showed its obsolescence.
In 1969, the RAN purchased another ten A-4G Skyhawks, primarily in order to replace the Sea Venoms on the carriers, instead of the proposed seventh and eighth Oberon-class submarines. These were operated together with the Sea Sabres in mixed units on board of Melbourne and from land bases, e.g. from NAS Nowra in New South Wales, where a number of Sea Sabres were also allocated to 724 Squadron for operational training.
Around 1970, Melbourne operated a standard air group of four jet aircraft, six Trackers, and ten Wessex helicopters until 1972, when the Wessexes were replaced with ten Westland Sea King anti-submarine warfare helicopters and the number of jet fighters doubled. Even though the A-4G’s more and more took over the operational duties on board of Melbourne, the Sea Sabres were still frequently deployed on the carrier, too, until the early Eighties, when both the Skyhawks and the Sea Sabres received once more a new camouflage, this time a wraparound scheme in two shades of grey, reflecting their primary airspace defense mission.
The CAC 27 Mk 41s’ last carrier operations took place in 1981 in the course of Melbourne’s involvements in two major exercises, Sea Hawk and Kangaroo 81, the ship’s final missions at sea. After Melbourne was decommissioned in 1984, the Fleet Air Arm ceased fixed-wing combat aircraft operation. This was the operational end of the Sabre Mk 41, which had reached the end of their airframe lifetime, and the Sea Sabre fleet had, during its career, severely suffered from accidents and losses: upon retirement, only eight of the original twenty-two aircraft still existed in flightworthy condition, so that the aircraft were all scrapped. The younger RAN A-4Gs were eventually sold to New Zealand, where they were kept in service until 2002.

The kit and its assembly:
This project was initially inspired by a set of decals from an ESCI A-4G which I had bought in a lot – I wondered if I could use it for a submission to the “In the navy” group build at whatifmodelers.com in early 2020. I considered an FJ-3M in Australian colors on this basis and had stashed away a Sword kit of that aircraft for this purpose. However, I had already built an FJ variant for the GB (a kitbashed mix of an F-86D and an FJ-4B in USMC colors), and was reluctant to add another Fury.
This spontaneously changed after (thanks to Corona virus quarantine…) I cleaned up one of my kit hoards and found a conversion set for a 1:72 CAC 27 from JAYS Model Kits which I had bought eons ago without a concrete plan. That was the eventual trigger to spin the RAN Fury idea further – why not a navalized version of the Avon Sabre for HMAS Melbourne?
The result is either another kitbash or a highly modified FJ-3M from Sword. The JAYS Model Kits set comes with a THICK sprue that carries two fuselage halves and an air intake, and it also offers a vacu canopy as a thin fallback option because the set is actually intended to be used together with a Hobby Craft F-86F.
While the parts, molded in a somewhat waxy and brittle styrene, look crude on the massive sprue, the fuselage halves come with very fine recessed engravings. And once you have cleaned the parts (NOTHING for people faint at heart, a mini drill with a saw blade is highly recommended), their fit is surprisingly good. The air intake was so exact that no putty was needed to blend it with the rest of the fuselage.
The rest came from the Sword kit and integrating the parts into the CAC 27 fuselage went more smoothly than expected. For instance, the FJ-3M comes with a nice cockpit tub that also holds a full air intake duct. Thanks to the slightly wider fuselage of the CAC 27, it could be mounted into the new fuselage halves without problems and the intake duct almost perfectly matches the intake frame from the conversion set. The tailpipe could be easily integrated without any mods, too. The fins had to be glued directly to the fuselage – but this is the way how the Sword kit is actually constructed! Even the FJ-3M’s wings match the different fuselage perfectly. The only modifications I had to make is a slight enlargement of the ventral wing opening at the front and at the read in order to take the deeper wing element from the Sword kit, but that was an easy task. Once in place, the parts blend almost perfectly into each other, just minor PSR was necessary to hide the seams!
Other mods include an extended front wheel well for the longer leg from the FJ-3M and a scratched arrester hook installation, made from wire, which is on purpose different from the Y-shaped hook of the Furies.
For the canopy I relied on the vacu piece that came with the JAYS set. Fitting it was not easy, though, it took some PSR to blend the windscreen into the rest of the fuselage. Not perfect, but O.K. for such a solution from a conversion set.
The underwing pylons were taken from the Sword kit, including the early Sidewinders. I just replaced the drop tanks – the OOB tanks are very wide, and even though they might be authentic for the FJ-3, I was skeptical if they fit at all under the wings with the landing gear extended? In order to avoid trouble and for a more modern look, I replaced them outright with more slender tanks, which were to mimic A-4 tanks (USN FJ-4s frequently carried Skyhawk tanks). They actually come from a Revell F-16 kit, with modified fins. The refueling probe comes from the Sword kit.
A last word about the Sword kit: much light, but also much shadow. While I appreciate the fine surface engravings, the recognizably cambered wings, a detailed cockpit with a two-piece resin seat and a pretty landing gear as well as the long air intake, I wonder why the creators totally failed to provide ANY detail of the arrester hook (there is literally nothing, as if this was a land-based Sabre variant!?) or went for doubtful solutions like a front landing gear that consists of five(!) single, tiny parts? Sadism? The resin seat was also broken (despite being packed in a seperate bag), and it did not fit into the cockpit tub at all. Meh!
Painting and markings:
From the start I planned to give the model the late RAN A-4Gs’ unique air superiority paint scheme, which was AFAIK introduced in the late Seventies: a two-tone wraparound scheme consisting of “Light Admiralty Grey” (BS381C 697) and “Aircraft Grey” (BS 381C 693). Quite simple, but finding suitable paints was not an easy task, and I based my choice on pictures of the real aircraft (esp. from "buzz" number 880 at the Fleet Air Arm Museum, you find pics of it with very good light condition) rather than rely on (pretty doubtful if not contradictive) recommendations in various painting instructions from models or decal sets.
I wanted to keep things simple and settled upon Dark Gull Grey (FS 36231) and Light Blue (FS 35414), both enamel colors from Modelmaster, since both are rather dull interpretations of these tones. Esp. the Light Blue comes quite close to Light Admiralty Grey, even though it should be lighter for more contrast to the darker grey tone. But it has that subtle greenish touch of the original BS tone, and I did not want to mix the colors.
The pattern was adapted from the late A-4Gs’ scheme, and the colors were dulled down even more through a light black ink wash. Some post-shading with lighter tones emphasized the contrast between the two colors again. And while it is not an exact representation of the unique RAN air superiority scheme, I think that the overall impression is there.
The cockpit interior was painted in very dark grey, while the landing gear, its wells and the inside of the air intake became white. A red rim was painted around the front opening, and the landing gear covers received a red outline, too. The white drop tanks are a detail I took from real world RAN A-4Gs - in the early days of the air superiority scheme, the tanks were frequently still finished in the old USN style livery, hence the white body but fins and tail section already in the updated colors.
The decals became a fight, though. As mentioned above, the came from an ESCI kit – and, as expected, the were brittle. All decals with a clear carrier film disintegrated while soaking in water, only those with a fully printed carrier film were more or less usable. One roundel broke and had to be repaired, and the checkered fin flash was a very delicate affair that broke several times, even though I tried to save and repair it with paint. But you can unfortunately see the damage.
Most stencils and some replacements (e. g. the “Navy” tag) come from the Sword FJ-3. While these decals are crisply printed, their carrier film is utterly thin, so thin that applying esp. the larger decals turned out to be hazardous and complicated. Another point that did not really convince me about the Sword kit.
Finally, the kit was sealed with matt acrylic varnish (Italeri) and some soot stains were added around the exhaust and the gun ports with graphite.
In the end, this build looks, despite the troubles and the rather exotic ingredients like a relatively simple Sabre with Australian markings, just with a different Navy livery. You neither immediately recognize the FJ-3 behind it, nor the Avon Sabre’s bigger fuselage, unless you take a close and probably educated look. Very subtle, though.
The RAN air superiority scheme from the late Skyhawks suits the Sabre/Fury-thing well – I like the fact that it is a modern fighter scheme, but, thanks to the tones and the colorful other markings, not as dull and boring like many others, e. g. the contemporary USN "Ghost" scheme. Made me wonder about an early RAAF F-18 in this livery - should look very pretty, too?

Nothing you see here is real, even though the model, the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
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:
The Lockheed Martin (originally developed by General Dynamics) F-16 Fighting Falcon is originally a single-engine multirole fighter aircraft, developed for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,500 aircraft have been built since production was approved in 1976. Although no longer being purchased by the U.S. Air Force, improved versions are still being built for export customers.
One of these recent developments is the AF-16 “Strike Falcon”, a thorough update of the original fighter design as a 4.5 generation aircraft and optimized for the attack role. The prototype was presented to the public at the 2012 Singapore Air Show, and the type is intended for the export market as a simpler and less costly alternative to the F-35 multi role SVTOL aircraft.
Compared to the original F-16 fighter the new attack aircraft underwent considerable modifications – the most obvious is a new wing with more area (effectively, almost doubling it) and a much thicker profile, a V-tail layout and a fixed Divertless Supersonic Intake (DSI).
The AF-16’s new delta wing was designed around a large single piece of carbon fiber composite material. The wing has a span of 11 meters, with a 55-degree leading edge sweep and can hold up to 20,000 pounds of fuel – extending range and loitering time considerable. The purpose of the high sweep angle was to allow for a thick wing section to be used while still providing limited transonic aerodynamic drag, and to provide a good angle for wing-installed conformal antenna equipment.
Another side effect of the new wing’s shape is a highly reduced radar signature, which was further improved by the angular, canted twin tail fins and the DSI’s design that absorbs much of incoming frontal radar beams and totally blocks the moving parts of the jet engine.
A simple afterburner nozzle for the F110-GE-100 afterburning turbofan was retained, even though a 2D and even 3D vectoring thrust nozzle could be mounted.
The AF-16 features the same AN/APG-68 of the F-16C/D Block 25, but it has been optimized for the ground attack role, even though air combat capabilities are retained. This includes improved ground-mapping, Doppler beam-sharpening, ground moving target indication, sea target, and track while scan (TWS) for up to 10 targets.
The system provides all-weather autonomous detection and targeting for Global Positioning System (GPS)-aided precision weapons, SAR mapping and terrain-following radar (TF) modes, as well as interleaving of all modes. The system is also fully compatibility with Lockheed Martin Low-Altitude Navigation and Targeting Infra-Red for Night (LANTIRN) system, which was integrated into the forward fuselage (instead of pods on the F-16).
The AF-16 quickly attained interest, and one of the first countries to order the Strike Falcon is Jordan. Jordan gained independence in 1946, but its first air bases had been set up in 1931 by the Royal Air Force. By 1950, Jordan began to develop a small air arm, which came to be known as the Arab Legion Air Force (ALAF).
In July of 1994, King Hussein of Jordan signed a peace treaty with Israel, ending over 40 years of hostility between these two nations. Shortly thereafter, the government of Jordan began to lobby within the American government to purchase as many as 42 F-16A/B Fighting Falcons.
In recent years, U.S. military assistance has been primarily directed toward upgrading Jordan’s air force, as recent purchases include upgrades to U.S.-made F-16 fighters, air-to-air missiles, and radar systems.
Following the 1994 Israel–Jordan peace treaty and the lending of Jordanian support to the United States during the Persian Gulf War, the U.S. recommenced full military relations with Jordan starting with the donation of 16 General Dynamics F-16 Fighting Falcon (12 F-16A and 4 F-16B) in storage at the Aerospace Maintenance and Regeneration Center (AMARC) at Davis Monthan AFB. Deliveries commenced in 1997 and were completed the following year, replacing the Mirage F1CJs in the air-defense role.
Other types, especially the ageing F-5E/F fleet, needed replacement, too. The RJAF’s F-5E/F, as well as the remaining Mirage F.1s in the ground support role, took several years after the F-16’s arrival until the AF-16A could finally fill this gap in the RJAF’s arsenal. Fourteen machines had been ordered in 2012 (twelve AF-16A single seaters plus two AF-16B two seaters for conversion training) and were delivered in early 2015, allocated to No. 1 Squadron at Azraq. For twelve more an option had been agreed upon, while the RJAF F-16As will focus on the interceptor and air superiority role.

The kit and its assembly:
This whif kitbashing was inspired by real design studies from General Dynamics that show evolutionary developments of the F-16 in a no-tail configuration, but with an enlarged diamond-shaped wing shape (much like the F-22's), obviously based on the F-16XL. Additionally you find several similar fantasy CG designs in the WWW – the basic idea seems to have potential. And when I stumbled across the remains of a Revell X-32 in my stash and an Intech F-16A kit, I wondered if these could not be reasonably combined...?
What sounds easy eventually ended up in a massive bodywork orgy. The Intech kit (marketed under the Polish Master Craft Label) is horrible, the worst F-16 kit I have ever seen or tried to build - it's cheap and you get what you pay for. Maybe the PM Model F-16 is worse (hard to believe, but sprue pics I saw suggest it), but the Intech kits are …challenging. This thing is like a blurred picture of an F-16: you recognize the outlines, but nothing is sharp and no part matches any other! Stay away.
Well, actually only the fuselage, the cockpit and parts of the Intech kit's landing gear survived. The X-32 kit is, on the other side, a sound offering. It was not complete anymore, since I donated parts like the cockpit and the landing gear to my SAAB OAS 41 'Vيًarr' stealth aircraft from Sweden some time ago, but there were many good parts left to work with.
Especially the aerodynamic surfaces (wings and V-tail) attained my interest: these parts match well with the F-16 fuselage in size and shape if you look from above, and the leading edges even blend well with the F-16 LERXs. But: the X-32's wings are much, much thicker than the F-16's, so that the original blended wing/fuselage intersection does not match at all.
Additionally, the X-32's bulged landing gear wells in the wings had to go, so these had to be filled as an initial step. The wing roots were roughly cut into the F-16 kit's shape and glued onto the fuselage. After drying, the whole blended wing/fuselage intersection had to be sculpted from scratch - several layers of putty and even more wet sanding sessions were necessary. I stopped counting after turn five, a tedious job. But it eventually paid out…
Furthermore decided to change the F-16's chin air intake and implant parts from the X-32 divertless supersonic "sugar scoop" intake. Such an arrangement has actually been tested on an F-16, so it's not too far-fetched, and its stealthy properties make a welcome update. The respective section from the X-32's lower front fuselage was cut away and had to be modified, too, because it would originally not fit at all under the F-16's front. The intake was carefully heated at the edges and the side walls bent inwards - I was lucky that no melting damage occurred! Inside of the new intake, the upper, bulged part was implanted, too, so that in real life the jet engine parts would be protected from direct frontal radar detection.
The front wheel position was retained. As a consequence of the new, much more voluminous and square air intake, the rather round section from the main landing gear onwards had to be sculpted for a decent new fuselage shape, too. But compared to the massive wing/fuselage body work, this was only a minor task.
The F-16A's fuselage was not extended, but for a different look I decided to eliminate the single fin and rather implant the X-32's outward-canted twin fins - the original extensions that hold the F-16's air brakes and now blend into the new wings' trailing edge were a perfect place, and as a side benefit they'd partly cover the jet nozzle. The latter was replaced by a respective spare part from an Italeri F-16 – the Intech nozzle is just a plain, conical tube!
The landing gear was mostly taken over from the Intech F-16, even though it is rather rough, as well as the pylons. The ordnance was puzzled together: the Sidewinders and the cropped drop tanks come from the Intech kit (the latter have a horribly oval diameter shape and the triangulare fins are a massive 1mm thick!), the Paveway bombs come from a Hasegawa air-to-ground weapons set.
Painting and markings:
The livery is somewhat inspired by a CG illustration of a fictional Big-Wing-F-16IN in Jordan colors. I also found a desert camouflage rather interesting for this aircraft – F-16s are typically grey-in-grey, with rare exceptions. Anyway, the paint scheme I applied is pure fiction fictional. I wanted a multi-color scheme with rather sober and subdued colors, partly inspired by contemporary Iranian MiG-29s.
I ended up with three upper and a single lower tone. The scheme is roughly based on the pattern that is applied to Venezuelan F-16s, but with desert colors: these are a pale, yellow-ish sand (Humbrol 103, Cream), a medium sand brown (Humbrol 187, Dark Stone) and a dull medium grey (Revell 75, RAL 7030). The undersides were painted in a pale blue (Humbrol 23, RAF Duck Egg Blue).
Since a lot of the (already rather vague) surface details of the Intech kit was lost through sanding, I simulated panels through dry painting, later some panel lines were manually added with a pencil, too. A light weathering was done with a thin black in wash. The cockpit was painted in Neutral Grey (FS 36173), and the canopy was tinted with a thinned mix of clear brown and yellow – and it turned out nicely! Even though the rear part had to be painted over, because the clear part’s fit with the rest of the fuselage was poor and putty had to be used to fill gaps and sculpt a decent rear end.
Most of the decals come from a Mirage F.1 decal sheet from FFSMC Productions, a French manufacturer. Together with the pale desert colors and the subdued RJAF markings, the AF-16A looks better and more coherent than expected, esp. after a uniform coat of matt acrylic varnish had been applied (from a rattle can).
A bold idea, with many doubts on the way, esp. because of the massive body sculpting. But once the kitbashed model was painted and sealed under matt varnish, things suddenly looked pretty cool – a positive surprise. Even though I will certainly never ever touch an Intech F-16 again…

Some background:
The Douglas F3D Skyknight (later designated F-10 Skyknight) was a United States twin-engined, mid-wing jet fighter aircraft manufactured by the Douglas Aircraft Company in El Segundo, California. The F3D was designed as a carrier-based all-weather night fighter and saw service with the United States Navy and United States Marine Corps. The mission of the F3D-2 was to search out and destroy enemy aircraft at night.
The F3D was not intended to be a typical sleek and nimble dogfighter, but as a standoff night fighter, packing a powerful radar system and a second crew member. It originated in 1945 with a US Navy requirement for a jet-powered, radar-equipped, carrier-based night fighter. The Douglas team led by Ed Heinemann designed around the bulky air intercept radar systems of the time, with side-by-side seating for the pilot and radar operator. The result was an aircraft with a wide, deep, and roomy fuselage. Instead of ejection seats, an escape tunnel was used.
As a night fighter that was not expected to be as fast as smaller daylight fighters, the expectation was to have a stable platform for its radar system and the four 20 mm cannon mounted in the lower fuselage. The F3D was, however, able to outturn a MiG-15 in an inside circle. The fire control system in the F3D-1 was the Westinghouse AN/APQ-35.
The AN/APQ-35 was advanced for the time, a combination of three different radars, each performing separate functions: an AN/APS-21 search radar, an AN/APG-26 tracking radar, both located in the nose, and an AN/APS-28 tail warning radar. The complexity of this vacuum tube-based radar system, which was produced before the advent of semiconductor electronics, required intensive maintenance to keep it operating properly.
The F3D Skyknight was never produced in great numbers but it did achieve many firsts in its role as a night fighter over Korea. While it never achieved the fame of the North American F-86 Sabre, it did down several Soviet-built MiG-15s as a night fighter over Korea with only one air-to-air loss of its own against a Chinese MiG-15 on the night of 29 May 1953.
In the years after the Korean War, the F3D was gradually replaced by more powerful aircraft with better radar systems. The F3D's career was not over though; its stability and spacious fuselage made it easily adaptable to other roles. The Skyknight played an important role in the development of the radar-guided AIM-7 Sparrow missile in the 1950s which led to further guided air-to-air missile developments.
In 1954, the F3D-2M was the first U.S. Navy jet aircraft to be fitted with an operational air-to-air missile: the Sparrow I,an all weather day/night BVR missile that used beam riding guidance for the aircrew to control the flight of the missile. Only 38 aircraft (12 F3D-1Ms, and 16 F3D-2Ms) were modified to use the missiles, though.
One of the F3D's main flaws, which it shared with many early jet aircraft, was its lack of power and performance. Douglas tried to mend this through a radical redesign: The resulting F3D-3 was the designation assigned to a swept-winged version (36° sweep at quarter chord) of the Skyknight. It was originally to be powered by the J46 turbojet, rated at 4.080 lbf for takeoff, which was under development but suffered serious trouble.
This led to the cancellation of the J46, and calculated performance of the F3D-3 with the substitute J34 was deemed insufficient. As an alternative the aircraft had to be modified to carry two larger and longer J47-GE-2 engines, which also powered the USN's FJ-2 "Fury" fighter.
This engine's thrust of 6.000 pounds-force (27 kN) at 7,950 rpm appeared sufficient for the heavy, swept-wing aircraft, and in 1954 an order for 287 production F3D-3s was issued, right time to upgrade the new type with the Sparrow I.
While the F3D-3's outline resembled that of its straight wing predecessors, a lot of structural changes had to be made to accommodate the shifted main wing spar, and the heavy radar equipment also took its toll: the gross weight climbed by more than 3 tons, and as a result much of the gained performance through the stronger engines and the swept wings was eaten away.
Maximum internal fuel load was 1.350 US gallons, plus a further 300 in underwing drop tanks. Overall wing surface remained the same, but the swept wing surfaces reduced the wing span.
In the end, thrust-to-weight ratio was only marginally improved and in fact, the F3D-3 had a lower rate of climb than the F3D-2, its top speed at height was only marginally higher, and stall speed climbed by more than 30 mph, making carrier landings more complicated.
It's equipment was also the same - the AN/APQ-35 was still fitted, but mainly because the large radar dish offered the largest detection range of any carrier-borne type of that time, and better radars that could match this performance were still under construction. Anyway, the F3D-3 was able to carry Sparrow I from the start, and this would soon be upgraded to Sparrow III (which became the AIM-7), and it showed much better flight characteristics at medium altitude.
Despite the ,many shortcomings the "new" aircraft represented an overall improvement over the F3D-2 and was accepted for service. Production of the F3D-3 started in 1955, but technology advanced quickly and a serious competitor with supersonic capability appeared with the McDonnell F3H Demon and the F4D Skyray - much more potent aircraft that the USN immediately preferred to the slow F3Ds. As a consequence, the production contract was cut down to only 102 aircraft.
But it came even worse: production of the swept wing Skyknight already ceased after 18 months and 71 completed airframes. Ironically, the F3D-3's successor, the F3H and its J40 engine, turned out to be more capricious than expected, which delayed the Demon's service introduction and seriously hampered its performance, so that the F3D-3 kept its all weather/night fighter role until 1960, and was eventually taken out of service in 1964 when the first F-4 Phantom II fighters appeared in USN service.
In 1962 all F3D versions were re-designated into F-10, the swept wing F3D-3 became the F-10C. The straight wing versions were used as trainers and also served as an electronic warfare platform into the Vietnam War as a precursor to the EA-6A Intruder and EA-6B Prowler, while the swept-wing fighters were completely retired as their performance and mission equipment had been outdated. The last F-10C flew in 1965.

The kit and its assembly:
Another project which had been on the list for some years now but finally entered the hardware stage. The F3D itself is already a more or less forgotten aircraft, and there are only a few kits available - there has been a vacu kit, the Matchbox offering and lately kits in 1:72 and 1:48 by Sword.
The swept wing F3D-3 remained on the drawing board, but would have been a very attractive evolution of the tubby Skyknight. In fact, the swept surfaces resemble those of the A3D/B-66 a Iot, and this was the spark that started the attempt to build this aircraft as a model through a kitbash.
This model is basically the Matchbox F3D coupled with wings from an Italeri B-66, even though, being much bigger, these had to be modified.
The whole new tail is based on B-66 material. The fin's chord was shortened, though, and a new leading edge (with its beautiful curvature) had to be sculpted from 2C putty. The vertical stabilizers also come from the B-66, its span was adjusted to the Skyknight's and a new root intersection was created from styrene and putty, so that a cross-shaped tail could be realized.
The tail radar dish was retained, even though sketches show the F3D-3 without it.
The wings were take 1:1 from the B-66 and match well. They just had to be shortened, I set the cut at maybe 5mm outwards of the engine pods' attachment points. They needed some re-engraving for the inner flaps, as these would touch the F3D-3's engines when lowered, but shape, depth and size are very good for the conversion.
On the fuselage, the wings' original "attachment bays" had to be filled, and the new wings needed a new position much further forward, directly behind the cockpit, in order to keep the CoG.
One big issue would be the main landing gear. On the straight wing aircraft it retracts outwards, and I kept this arrangement. No detail of the exact landing gear well position was available to me, so I used the Matchbox parts as stencils and placed the new wells as much aft as possible, cutting out new openings from the B-66 wings.
The OOB landing gear was retained, but I added some structure to the landing gear wells with plastic blister material - not to be realistic, just for the effect. A lot of lead was added in the kit's nose section, making sure it actually stands on the front wheel.
The Matchbox Skyknight basically offers no real problems, even though the air intake design leaves, by tendency some ugly seams and even gaps. I slightly pimped the cockpit with headrests, additional gauges and a gunsight, as well as two (half) pilot figures. I did not plan to present the opened cockpit and the bulbous windows do not allow a clear view onto the inside anyway, so this job was only basically done. In fact, the pilots don't have a lower body at all...
Ordnance comprises of four Sparrow III - the Sparrow I with its pointed nose could have been an option, too, but I think at the time of 1960 the early version was already phased out?
Painting and markings:
This was supposed to become a typical USN service aircraft of the 60ies, so a grey/white livery was predetermined. I had built an EF-10B many years ago from the Matchbox kit, and the grey/white guise suits the Whale well - and here it would look even better, with the new, elegant wings.
For easy painting I used semi matt white from the rattle can on the lower sides (painting the landing gear at the same time!), and then added FS 36440 (Light Gull Grey, Humbrol 129) with a brush to the upper sides. The radar nose became semi matt black (with some weathering), while the RHAWS dish was kept in tan (Humbrol 71).
In order to emphasize the landing gear and the respective wells I added a red rim to the covers.
The cockpit interior was painted in dark grey - another factor which made adding too many details there futile, too...
The aircraft's individual marking were to be authentic, and not flamboyant. In the mid 50ies the USN machines were not as colorful as in the Vietnam War era, that just started towards the 60ies.
The markings I used come primarily from an Emhar F3H Demon, which features no less than four(!) markings, all with different colors. I settled for a machine of VF-61 "Jolly Rogers", which operated from the USS Saratoga primarily in the Mediterranean from 1958 on - and shortly thereafter the unit was disbanded.
I took some of the Demon markings and modified them with very similar but somewhat more discrete markings from VMF-323, which flew FJ-4 at the time - both squadrons marked their aircraft with yellow diamonds on black background, and I had some leftover decals from a respective Xtradecal sheet in the stash.
IMHO a good result with the B-66 donation parts, even though I am not totally happy with the fin - it could have been more slender at the top, and with a longer, more elegant spine fillet, but for that the B-66 fin was just too thick. Anyway, I am not certain if anyone has ever built this aircraft? I would not call the F3D-3 elegant or beautiful, but the swept wings underline the fuselage's almost perfect teardrop shape, and the thing reminds a lot of the later Grumman A-6 Intruder?

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!

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.

Some background:
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym.
They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (Sekcja Lotnicza Koła Mechaników Studentów), where they manufactured their first designs. From 1926 they designed several aircraft alone, in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Polish Air Force’s Okęcie aerodrome, today's Warsaw International Airport.
At first, the RWD team designed and built light sportsplanes. Early designs were built in small series and used in Polish sports aviation, including their debut at the Challenge 1930 international contest. Their next designs performed particularly well in competitions - the RWD-6 won the Challenge 1932 and RWD-9s won the Challenge 1934 international contest. The sportsplane RWD-5 was the lightest plane to fly across the Atlantic in 1933. Three types saw mass production: the RWD-8, which became the Polish Air Force basic trainer, the RWD-13 touring plane and the RWD-14 Czapla reconnaissance plane. Other important designs were the RWD-10 aerobatic plane (1933), RWD-17 aerobatic-trainer plane (1937) and RWD-21 light sport plane (1939). Their most ambitious design that entered the hardware stage and eventually took to flight was the RWD-24, a fighter aircraft. However, World War II prevented further development and serial production of later RWD designs, and also put an end to the RWD construction bureau and its workshops.
The RWD-24 had been designed in response to a requirement for a fighter issued by the Polish Air Force in 1934. RWD responded and built a prototype of mixed materials, heavily influenced by French designs and resources, since Poland had procured several fighter, bomber and reconnaissance aircraft from France during the mid-twenties.
RWD’s design team quickly projected that only a monoplane design would be capable of delivering the desired level of performance sought; other modern features were to include a fully enclosed cockpit, a variable-pitch propeller, and landing flaps. The resulting RWD-24 was a high-wing monoplane of mixed construction, with fabric-covered wooden tail and rudders. The wings were directly attached to the upper fuselage and braced. They consisted of a two-spar duralumin structure, complete with rivetted ribs to both the spars and skin. The exterior of the wing was covered by finely corrugated duralumin sheet, while the slotted ailerons had a fabric covering.
Power came from a water-cooled Hispano-Suiza Y V12 engine – a novelty among Polish fighter designs, which traditionally relied upon radial engines, e.g. the Bristol Mercury and Jupiter, imported as license builds from Czechoslovakia (Skoda). The Hispano-Suiza engine meant a considerable step forward, though, since it increased the output by almost +50%, with appreciable improvements of overall performance that promised to put the RWD-24 on eye level with other contemporary foreign monoplane fighters.
In order to improve performance further, much effort was put into aerodynamic effectiveness, despite a rather conservative structure with bracing struts for the wings and stabilizers. For instance, the ventral radiator could be retracted manually, adapting the frontal area to the engine’s cooling needs. The RWD-24’s landing gear was fixed but covered with aerodynamic fairings and spats.
Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.404 cannon with 60 rounds from a drum magazine, mounted as a “moteur canon” between the cylinder banks and firing through the propeller hub, plus two pairs of 7.92 mm (0.312 in) KM Wz 33 machine guns with 450 RPG in the wings outside of the propeller disc. The prototypes only carried the cannon and a single pair of machine guns, though.
First flown by RWD-founder Jerzy Drzewiecki himself, the first prototype demonstrated the type's favorable flying characteristics from the onset – even though the poor field of view for the pilot ahead and downwards during landing and taxiing was criticized. Another critical point was the retractable radiator; while it allowed a remarkable boost in top speed for short periods, the manual temperature management – esp. during combat situations – turned out to be impractical and an automated solution was requested. The firepower of the 20mm cannon received praise, too, despite its limited ammunition capacity. After 80 hours of test flights, in January 1936, the prototype was delivered with all military equipment fitted to the Polish Air Force at Okęcie aerodrome to participate in service trials, while a second prototype was built in parallel and joined the program in May. It differed from the first RWD-24 through a different tail section, which was covered with a bonded metal/wood material (Plymax) skin fixed to duralumin tubing.
Despite its good handling qualities and impressive performance (the contemporary Polish standard fighter, the PZL P.11, had a top speed of 390 km/h (240 mph, 210 kn), while the RWD-24 surpassed 440 km/h (273 mph, 240 kn) at ideal altitude), both the shape and basic configuration of the RWD-24 were hotly contended, particularly between 'traditional' advocates of biplane aircraft and supporters of 'modern' monoplane with retractable landing gear. The RWD-24 would not satisfy either party, and the high wing layout offered no real development potential, together with the field of view issues. Only a complete redesign of the RWD-24 into a low-wing configuration with a retractable landing gear would have been a viable solution. RWD engineers deemed this task to be feasible, but the Polish Air Force did not want to wait any longer for a new fighter aircraft. In consequence, the RWD-24’s development was officially stopped in early 1938, after only two airframes had been built. In the meantime, RWD had also started work on a dedicated low-wing fighter powered by a 800 hp (597 kW) Gnome-Rhône Mars radial engine, the RWD-25, but until then only a mock-up of this alternative type had been built.
However, the two RWD-24 prototypes remained based at Okęcie and were further tested by both the company and by the Polish Air Force. During these test in 1938, the RWD-24s were, among others, evaluated against a Hawker Hurricane Mk.I and a Dewoitine D.520 that had been delivered to Poland for trials (and eventual sales). In the meantime, driven by rising political tensions and threatened by neighboring Germany, the Polish Air Force had started to follow the idea of importing fully developed monoplane fighters in order to quickly boost the country’s air power and deterrent potential. This eventually led to the procurement of Hawker Hurricanes from Great Britain in 1939. But this decision came too late: the fighters were not delivered before 1 September 1939, when Germany invaded Poland, and the Polish Hurricanes on order were alternatively sent to Turkey instead.
Upon the German invasion the RWD-24 prototypes were, together with most other active Polish combat aircraft, dispersed to secondary airfields and allocated to the so-called Pursuit Brigade, deployed in the Warsaw area, where both served until they became unserviceable after a week, due to their exotic nature. Their fate remains unclear, though, since both machines disappeared. But most likely they were both destroyed within two weeks, like 70% of the Polish Air Force’s aircraft.

The kit and its assembly:
This was a rather spontaneous submission for the “Prototypes” group build at whatifmodelers.com in July 2020, originally spawned by the idea of retrograding a Morane Saulnier MS.406 into a biplane with a fixed landing gear, a kind of French Gloster Gladiator. However, this changed when I found a surplus Mistercraft PZL P.7 kit in the stash, which had been part of a combo deal some time ago. Why not use it for a kitbashing and create a late interwar period Polish fighter prototype from the MS.406…?
The MS.406 fuselage comes from the simple Hobby Boss kit, even though some serious bodywork had to be done in order to make the low wing attachment points and the respective large wing root fairings disappear – on the simple Hobby Boss kit, wings and lower fuselage are one integral part, so that some major cutting and PSR were necessary to create a new, “clean” lower fuselage. For the new wings a piece of the cowling in front of the windscreen had to be cut out, the result looks very natural, though, the P.7 wing literally fell into place. The P.7 wings were taken, together with their respective support struts, wholesale from the Mistercraft kit, I just added flaps and lowered them, and I added fairings under the wings for the machine guns – OOB the kit comes with shallow holes that look a bit strange?
The empennage was taken over from the MS.406, but the stabilizers were replaced with the P.7’s, because they were bigger and their shape matches the fin so well. The fixed landing gear is a donor from an ICM Heinkel He 51 floatplane (surplus parts), it was just shortened by about 2mm in order to avoid an exaggerated nose-up stance due to the high propeller position.
The cockpit was taken OOB, just a pilot figure was added to hide the Hobby Boss kit’s rather basic interior.
Painting and markings:
Prototype liveries tend to be dry affairs, and therefore my RWD-24 received a standard pre-WWII livery for Polish aircraft in a uniform brownish-green khaki (”Light Polish Khaki”) over light blue wing undersides. For the very unique khaki tone I used Modelmaster 1711 (FS 34087, a rather yellowish interpretation of this tone), while the wings’ undersides were painted with Humbrol 65 (Aircraft Blue). The khaki tone was - on Polish high wing aircraft of the time - typically carried on the whole fuselage, including the undersides, so I adopted the tone for the complete landing gear and the wing struts, too. For a little more variety, I gave the engine a cowling in a bare metal finish (Humbrol Polished Aluminum Metallizer) and the airframe parts that are covered with fabric were apinted with Humbrol 155 - FS 34087, too, but a morre greenish and darker interpretation of this tone.
The kit received a black ink washing and some post-shading through dry-brushing of single panels with lighter tones. The cockpit interior was painted in a medium grey, the propeller blades became Revell 99 (Aluminum) with red tips, a black spinner and partly blackened back sides (in order to avoid light reflections that could blind the pilot).
Most markings come from a Polish aircraft aftermarket sheet. The red lightning cheatline on the fuselage and on the wings were borrowed from Indonesian MiG-21Fs (from two Begemot sheets). The contrast to the khaki is not strong, but I thought that some decoration would suit a prototype fighter well. The tactical codes consist of single white and black letters (both TL Modellbau stuff).
After some exhaust and gun soot stains the model was finally sealed with matt acrylic varnish, just the metallic cowling and the spinner received a light shine.
While the outcome looks rather unsuspicious, this kitbashing was a lot of work – esp. the landing gear and the cosmetic surgery to remove the MS.406’s lower wings was more demanding than I had thought at first. But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.

But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.
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!

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.

Full Story:
Supermarine (Type 250) Shrike Mk1
Following the lessons learned from their failed Type 224, Supermarine’s next fighter project was initially a private venture and not to any specific Ministry requirements; they aimed to produce an aircraft that used proven technology while still offering a significant step up in capability. While more powerful engines were in the pipeline the proven Rolls Royce Kestrel was selected albeit with some modest tweaks to the supercharger and intake system to increase its performance, all metal monocoque construction was employed based on their experience with the Type 224 and their Schneider Trophy winning seaplanes. Named Shrike after the small predatory songbird the result was an aircraft touted in the press as the world’s first 300mph Interceptor, in reality the Shrike could only just attain 280mph under test conditions and operationally less than that but it still represented a healthy leap in performance over the Hawker Fury and Gloster Gauntlet it was intended to replace. Although no Specification existed to suit the Shrike one was created to hasten the RAFs entry into the Monoplane era and to ensure it stayed at the fore front of aviation technology, and so in July 1936 the Supermarine Shrike Mk1 entered service with 56 Squadron at RAF North Weald; the squadron had little time to get accustomed to their new mounts as Britain had decided to show solidarity with The Kingdom of Ethiopia (then commonly known as Abyssinia) in its occupation by Italian forces.
The RAF’s newest fighter was to be deployed but only to operate in a purely defensive capacity in the hope that their presence would stop aerial attacks, allowing the Ethiopian forces to at least hold their own. The League of Nations failure to oppose Italy’s occupation of Abyssinia had emboldened Germany’s chancellor Adolf Hitler who in March 1936 had marched troops into the Rhineland, Britain, fearing Italy would look to do the same towards their interests in the Mediterranean, chose to use the Abyssinia Crisis as an opportunity for a show of force as a deterrent to such aspirations. In December 1936 the RAF deployed 56 Squadron along with two squadrons of Hawker Harts which immediately began patrols, this initially had the desired effect, the Ethiopian Troops had been mercilessly gassed and strafed and the sight of patrolling Shrikes had an instant effect on moral; this however was to be short lived.
On New year’s day 1937 the Regia Aeronuatica attacked the RAF field at Addis Ababa damaging several aircraft but ultimately only causing minor damage, the first shots however had been fired and on 3rd January the RAF retaliated with a low level attack; the shooting war had begun proper. Attacks by formations of SM.81 bombers escorted by Fiat CR32 fighters quickly became the order of the day and 56 Squadron found itself engaged in WW1 style dogfights with the nimble Fiats, the Shrike had a higher top speed and could out climb and dive the biplane fighters but the Italians had the edge in roll and turn rate; the Ethiopian forces were mesmerized watching the melee occurring over their heads and would often risk standing out in the open during bombing raids to cheer on the RAF.
War had never actually been declared between Italy and Great Britain and this was still seen as something of a skirmish by the worlds Press, this changed on February 1st when Italy launched a pre-emptive strike on British forces on the island of Malta sinking HMS Glorious and damaging several other Royal Navy ships in Grand Harbour. The Anglo-Italo war had begun.

Some background:
Although the performance increases of jet-powered aircraft introduced towards the end of World War II over their piston-powered ancestors were breathtaking, there were those at the time who believed that much more was possible. As far back as 1943, the British Ministry of Aircraft Production had issued a specification designated "E.24/43" for a supersonic experimental jet aircraft that would be able to achieve 1,600 KPH (1,000 MPH).
Beginning in 1946, a design team at English Electric (EE) under W.E.W. "Teddy" Petter began design studies for a supersonic fighter, leading to award of a Ministry of Supply (MoS) contract in 1947 under specification "ER.103" for a design study on an experimental aircraft that could achieve Mach 1.2.
The MoS liked the EE concepts, and in early 1949 awarded the company a contract under specification "F.23/49" for two flying prototypes and one ground-test prototype of the "P.1".
The P.1 was defined as a supersonic research aircraft, though the design had provisions for armament and a radar gunsight. It incorporate advanced and unusual design features, such as twin turbojet engines mounted one above the other to reduce aircraft frontal area; and strongly swept wings, with the wingtip edges at a right angle to the fuselage, giving a wing configuration like that of a delta wing with the rear inner corners cut out. The aircraft featured an elliptical intake in the nose.
The P.1's performance was so outstanding that the decision was quickly made to proceed on an operational version that would be capable of Mach 2. In fact, the second P.1 prototype featured items such as a bulged belly tank and fit of twin Aden Mark 4 30 millimeter revolver-type cannon, bringing it closer to operational specification.
Orders were placed for three "P.1B" prototypes for a production interceptor and the original P.1 was retroactively designated "P.1A". The P.1B featured twin Rolls-Royce Avon afterburning engines and a larger tailfin. An airborne intercept (AI) radar was carried in the air intake shock cone, which was changed from elliptical to circular. The cockpit was raised for a better field of view and the P.1B was armed with two Aden cannon in the upper nose, plus a pack under the cockpit that could either support two De Havilland Blue Jay (later Firestreak) heat-seeking AAMs or 44 Microcell 5 centimeter (2 inch) unguided rockets.
The initial P.1B prototype performed its first flight on 4 April 1957 and the type entered RAF service as EE Lightning F.1. RAF Number 74 Squadron at Coltishall was the first full service unit, with the pilots acquiring familiarization with the type during late 1960 and the squadron declared operational in 1961.
However, while the Lightning was developed further into more and more advanced versions. Its concept was also the basis for another research aircraft that would also be developed into a high performance interceptor: the P.6/1, which later became the “Levin” fighter.
P.6 encompassed a total of four different layouts for a Mach 2+ research aircraft, tendering to ER.134T from 1952. P.6/1 was the most conservative design and it relied heavily on existing (and already proven) P.1 Lightning components, primarily the aerodynamic surfaces. The most obvious difference was a new fuselage of circular diameter, housing a single Rolls Royce RB.106 engine.
The RB.106 was a two-shaft design with two axial flow compressors each driven by its own single stage turbine and reheat. It was of similar size to the Rolls-Royce Avon, but it produced about twice the thrust at 21,750 lbf (96.7 kN) in the initial version. The two-shaft layout was relatively advanced for the era; the single-shaft de Havilland Gyron matched it in power terms, while the two-spool Bristol Olympus was much less powerful at the then-current state of development. Apart from being expected to power other British aircraft such as those competing for Operational Requirement F.155, it was also selected to be the powerplant for the Avro Canada CF-105 Arrow and led to the Orenda Iroquois engine, which even reach 30.000 lbf (130 kN).
The P.6/1 was eventually chosen by the MoS for further development because it was regarded as the least risky and costly alternative. Beyond its test bed role for the RB.106 the P.6/1 was also seen as a potential basis for a supersonic strategic air-to-ground missile (similar to the massive Soviet AS-3 ‘Kangaroo’ cruise missile) and the starting point for an operational interceptor that would be less complex than the Lightning, but with a comparable if not improved performance but a better range.
In 1955 English Electric received a go ahead for two P.6/1 research aircraft prototypes. Despite a superficial similarity to the Lightning, the P.6/1’s internal structure was very different. The air duct, for instance, was bifurcated and led around on both sides of the cockpit tub and the front wheel well instead of below it. Further down, the duct ran below the wing main spar and directly fed the RB.106.
The rear fuselage was area-ruled, the main landing gear retracted, just like the Lightning’s, outwards into the wings, while the front wheel retracted backwards into a well that was placed further aft than on the Lightning. The upper fuselage behind the main wings spar carried fuel tanks, more fuel was carried in wing tanks.
Both research machines were ready in 1958 and immediately started with aerodynamic and material tests for the MoS, reaching top speeds of Mach 2.5 and altitudes of 60.000 ft. and more.
In parallel, work on the fighter version, now called “Levin”, had started. The airframe was basically the same as the P.6/1’s. Biggest visible changes were a wider air intake with a bigger central shock cone (primarily for a radar dish), a shorter afterburner section and an enlarged fin with area increased by 15% that had become necessary in order to compensate instability through the new nose layout and the potential carriage of external ordnance, esp. under the fuselage. This bigger fin was taken over to the Lightning F.3 that also initially suffered from longitudal instability due to the new Red Top missiles.
The Levin carried armament and avionics similar to the Lightning, including the Ferranti-developed AI.23 monopulse radar. The aircraft was to be fully integrated into a new automatic intercept system developed by Ferranti, Elliot, and BAC. It would have turned the fighters into something like a "manned missile" and greatly simplified intercepts.
Anyway, the Levin’s weapon arrangement was slightly different from the Lightning: the Levin’s armament comprised theoretically a mix of up to four 30mm Aden cannons and/or up to four of the new Red Top AAMs, or alternatively the older Firestreak. The guns were mounted in the upper nose flanks (similar to the early Lightning arrangement, but set further back), right under the cockpit hatch, while a pair of AAMs was carried on wing tip launch rails. Two more AAMs could be carried on pylons under the lower front fuselage, similar to the Lightning’s standard configuration, even though there was no interchangeable module. Since this four-missile arrangement would not allow any cannon to be carried anymore and caused excessive drag, the typical payload was limited to two Aden cannons and the single pair of wing-tip missiles.
Despite its proven Lightning ancestry, the development of the Levin went through various troubles. While the RB.106 worked fine in the research P.6/1, it took until 1962 that a fully reliable variant for the interceptor could be cleared for service. Meanwhile the Lightning had already evolved into the F.3 variant and political discussions circled around the end of manned military aircraft. To make matters even worse, the RAF refused to buy the completely automatic intercept system, despite the fact that it had been fully engineered at a cost of 1.4 million pounds and trialed in one of the P.1Bs.
Eventually, the Levin F.1 finally entered service in 1964, together with the Lightning F.3. While the Lightning was rather seen as a point defense interceptor, due to the type’s limited range: If a Lightning F.3 missed its target on its first pass, it almost never had enough fuel to make a second attempt without topping off from a tanker, which would give an intruder plenty of time to get to its target and then depart… The Lightning’s flight endurance was less than 2 hours (in the F.2A, other variants even less), and it was hoped that the Levin had more potential through a longer range. Anyway, in service, the Levin’s range in clean configuration was only about 8% better than the Lightning’s. The Levin F.1’s flight endurance was about 2 ½ hours – an improvement, but not as substantial as expected.
In order to improve the range on both fighters, English Electric developed a new, stiffened wing for the carriage of a pair of jettisonable overwing ferry tanks with a capacity of 1,182 liters (312 US gallons / 260 Imperial gallons, so-called “Overburgers”). The new wing also featured a kinked leading edge, providing better low-speed handling. From mid 1965 onwards, all Levins were directly produced in this F.2 standard, and during regular overhauls the simpler F.1 machines were successively updated. The Lightning introduced the kinked wing with the F.3A variant and it was later introduced with the F.2A and F.6A variants.
Levin production comprised 21 original F.1 airframes, plus 34 F.2 fighters, and production was stopped in 1967. A trainer version was not produced, the Lightning trainers were deemed sufficient for conversion since the Levin and the Lightning shared similar handling characteristics.
The Levin served only with RAF 29 and 65 Squadron, the latter re-instated in 1970 as a dedicated fighter squadron. When in November 1984 the Tornado squadrons began to form, the Levin was gradually phased out and replaced until April 1987 by the Tornado F.3.

The kit and its assembly:
Another contribution to the Cold War GB at whatifmodelers.com, and the realization of a project I had on the agenda for long. The EE P.6/1 was a real project for a Mach 2+ research aircraft, as described above, but it never went off the drawing board. Its engine, the RB.106, also never saw the light of day, even though its later career as the Canadian Orenda Iroquois for the stillborn CF-105.
Building this aircraft as a model appears simple, because it’s a classic Lightning (actually a F.1 with the un-kinked wing and the small fin), just with a single engine and a rather tubular fuselage. But creating this is not easy at all…
I did not want to replicate the original P.6/1, but rather a service aircraft based on the research aircraft. Therefore I used parts from a Lightning F.6 (a vintage NOVO/Frog kit). For the fuselage I settled for a Su-17, from a MasterCraft kit. The kit’s selling point was its small price tag and the fuselage construction: the VG mechanism is hidden under a separate spine piece, and I wanted to transplant the Lightning’s spine and cockpit frame, so I thought that this would make things easier.
Nope.
Putting the parts from the VERY different kits/aircraft together was a major surgery feat, with several multiple PSR sessions on the fuselage, the air intake section (opened and fitted with both an internal splitter and a bulkhead to the cockpit section), the wings, the stabilizers, the fin… This model deserves the title “kitbash” like no other, because no major sections had ever been intended to be glued together, and in the intended position!
The landing gear was more or less taken OOB, but the main struts had to be elongated by 2mm – somehow the model turned out to be a low-riding tail sitter! The cockpit interior was improvised, too, consisting of a Su-17 cockpit tub, a scratched dashboard and a Martin Baker ejection seat from an Italeri Bae Hawk trainer.
Since most of the fuselage surface consists of various materials (styrene and two kinds of putty), I did not dare to engrave panel lines – after all the PSR work almost any surface detail was gone. I rather went for a graphic solution (see below). Some antennae and air scoops were added, though.
The overwing tanks come OOB from the NOVO kit, as well as the Red Top missiles, which ended up on improvised wing tip launch rails, based on design sketches for Lightning derivatives with this layout.
Colors and markings:
There are several “classic” RAF options, but I settled for a low-viz Eighties livery taken from BAC Lightnings. There’s a surprising variety of styles, and my version is a mix of several real world aircraft.
I settled for Dark Sea Grey upper surfaces (Modelmaster Authentic) with a high waterline, a fuselage completely in Medium Sea Grey (Humbrol 165 – had to be applied twice because the first tin I used was obviously old and the paint ended up in a tone not unlike PRU Blue!) and Light aircraft Grey underwing surfaces (Humbrol 166). The leading edges under the wings are Dark Sea Grey, too.
The cockpit interior was painted in dark grey (Humbrol 32 with some dry-brushing), while the landing gear is Aluminum (Humbrol 56).
Once the basic painting was done I had to deal with the missing panel lines on the fuselage and those raised lines that were sanded away during the building process. I decided to simulate these with a soft pencil, after the whole kit was buffed with a soft cotton cloth and some grinded graphite. This way, the remaining raised panel lines were emphasized, and from these the rest was drawn up. A ruler and masking tape were used as guidance for straight lines, and this worked better than expected, with good results.
As a next step, the newly created panels were highlighted with dry-brushed lighter tones of the basic paints (FS 36492 and WWII Italian Blue Grey from Modelmaster, and Humbrol 126), more for a dramatic than a weathered effect. The gun ports and the exhaust section were painted with Modelmaster Metallizer (Titanium and Magnesium).
The decals come from several Xtradecal aftermarket sheets, including a dedicated Lightning stencils sheet, another Lightning sheet with various squadron markings and a sheet for RAF Tornado ADVs.
The code number “XS970” was earmarked to a TSR.2, AFAIK, but since it was never used on a service aircraft it would be a good option for the Levin.
The kit received a coat of matt acrylic varnish from the rattle can – jn this case the finish was intended to bear a slight shine.
This was a project with LOTS of effort, but you hardly recognize it – it’s a single engine Lightning, so what? But welding the Lightning and Su-17 parts together for something that comes close to the P.6/1 necessitated LOTS of body work and improvisation, carving it from wood would probably have been the next complicated option. Except for the surprisingly long tail I am very happy with the result, despite the model’s shaggy origins, and the low-viz livery suits the sleek aircraft IMHO very well.

Some background:
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym.
They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (Sekcja Lotnicza Koła Mechaników Studentów), where they manufactured their first designs. From 1926 they designed several aircraft alone, in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Polish Air Force’s Okęcie aerodrome, today's Warsaw International Airport.
At first, the RWD team designed and built light sportsplanes. Early designs were built in small series and used in Polish sports aviation, including their debut at the Challenge 1930 international contest. Their next designs performed particularly well in competitions - the RWD-6 won the Challenge 1932 and RWD-9s won the Challenge 1934 international contest. The sportsplane RWD-5 was the lightest plane to fly across the Atlantic in 1933. Three types saw mass production: the RWD-8, which became the Polish Air Force basic trainer, the RWD-13 touring plane and the RWD-14 Czapla reconnaissance plane. Other important designs were the RWD-10 aerobatic plane (1933), RWD-17 aerobatic-trainer plane (1937) and RWD-21 light sport plane (1939). Their most ambitious design that entered the hardware stage and eventually took to flight was the RWD-24, a fighter aircraft. However, World War II prevented further development and serial production of later RWD designs, and also put an end to the RWD construction bureau and its workshops.
The RWD-24 had been designed in response to a requirement for a fighter issued by the Polish Air Force in 1934. RWD responded and built a prototype of mixed materials, heavily influenced by French designs and resources, since Poland had procured several fighter, bomber and reconnaissance aircraft from France during the mid-twenties.
RWD’s design team quickly projected that only a monoplane design would be capable of delivering the desired level of performance sought; other modern features were to include a fully enclosed cockpit, a variable-pitch propeller, and landing flaps. The resulting RWD-24 was a high-wing monoplane of mixed construction, with fabric-covered wooden tail and rudders. The wings were directly attached to the upper fuselage and braced. They consisted of a two-spar duralumin structure, complete with rivetted ribs to both the spars and skin. The exterior of the wing was covered by finely corrugated duralumin sheet, while the slotted ailerons had a fabric covering.
Power came from a water-cooled Hispano-Suiza Y V12 engine – a novelty among Polish fighter designs, which traditionally relied upon radial engines, e.g. the Bristol Mercury and Jupiter, imported as license builds from Czechoslovakia (Skoda). The Hispano-Suiza engine meant a considerable step forward, though, since it increased the output by almost +50%, with appreciable improvements of overall performance that promised to put the RWD-24 on eye level with other contemporary foreign monoplane fighters.
In order to improve performance further, much effort was put into aerodynamic effectiveness, despite a rather conservative structure with bracing struts for the wings and stabilizers. For instance, the ventral radiator could be retracted manually, adapting the frontal area to the engine’s cooling needs. The RWD-24’s landing gear was fixed but covered with aerodynamic fairings and spats.
Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.404 cannon with 60 rounds from a drum magazine, mounted as a “moteur canon” between the cylinder banks and firing through the propeller hub, plus two pairs of 7.92 mm (0.312 in) KM Wz 33 machine guns with 450 RPG in the wings outside of the propeller disc. The prototypes only carried the cannon and a single pair of machine guns, though.
First flown by RWD-founder Jerzy Drzewiecki himself, the first prototype demonstrated the type's favorable flying characteristics from the onset – even though the poor field of view for the pilot ahead and downwards during landing and taxiing was criticized. Another critical point was the retractable radiator; while it allowed a remarkable boost in top speed for short periods, the manual temperature management – esp. during combat situations – turned out to be impractical and an automated solution was requested. The firepower of the 20mm cannon received praise, too, despite its limited ammunition capacity. After 80 hours of test flights, in January 1936, the prototype was delivered with all military equipment fitted to the Polish Air Force at Okęcie aerodrome to participate in service trials, while a second prototype was built in parallel and joined the program in May. It differed from the first RWD-24 through a different tail section, which was covered with a bonded metal/wood material (Plymax) skin fixed to duralumin tubing.
Despite its good handling qualities and impressive performance (the contemporary Polish standard fighter, the PZL P.11, had a top speed of 390 km/h (240 mph, 210 kn), while the RWD-24 surpassed 440 km/h (273 mph, 240 kn) at ideal altitude), both the shape and basic configuration of the RWD-24 were hotly contended, particularly between 'traditional' advocates of biplane aircraft and supporters of 'modern' monoplane with retractable landing gear. The RWD-24 would not satisfy either party, and the high wing layout offered no real development potential, together with the field of view issues. Only a complete redesign of the RWD-24 into a low-wing configuration with a retractable landing gear would have been a viable solution. RWD engineers deemed this task to be feasible, but the Polish Air Force did not want to wait any longer for a new fighter aircraft. In consequence, the RWD-24’s development was officially stopped in early 1938, after only two airframes had been built. In the meantime, RWD had also started work on a dedicated low-wing fighter powered by a 800 hp (597 kW) Gnome-Rhône Mars radial engine, the RWD-25, but until then only a mock-up of this alternative type had been built.
However, the two RWD-24 prototypes remained based at Okęcie and were further tested by both the company and by the Polish Air Force. During these test in 1938, the RWD-24s were, among others, evaluated against a Hawker Hurricane Mk.I and a Dewoitine D.520 that had been delivered to Poland for trials (and eventual sales). In the meantime, driven by rising political tensions and threatened by neighboring Germany, the Polish Air Force had started to follow the idea of importing fully developed monoplane fighters in order to quickly boost the country’s air power and deterrent potential. This eventually led to the procurement of Hawker Hurricanes from Great Britain in 1939. But this decision came too late: the fighters were not delivered before 1 September 1939, when Germany invaded Poland, and the Polish Hurricanes on order were alternatively sent to Turkey instead.
Upon the German invasion the RWD-24 prototypes were, together with most other active Polish combat aircraft, dispersed to secondary airfields and allocated to the so-called Pursuit Brigade, deployed in the Warsaw area, where both served until they became unserviceable after a week, due to their exotic nature. Their fate remains unclear, though, since both machines disappeared. But most likely they were both destroyed within two weeks, like 70% of the Polish Air Force’s aircraft.

The kit and its assembly:
This was a rather spontaneous submission for the “Prototypes” group build at whatifmodelers.com in July 2020, originally spawned by the idea of retrograding a Morane Saulnier MS.406 into a biplane with a fixed landing gear, a kind of French Gloster Gladiator. However, this changed when I found a surplus Mistercraft PZL P.7 kit in the stash, which had been part of a combo deal some time ago. Why not use it for a kitbashing and create a late interwar period Polish fighter prototype from the MS.406…?
The MS.406 fuselage comes from the simple Hobby Boss kit, even though some serious bodywork had to be done in order to make the low wing attachment points and the respective large wing root fairings disappear – on the simple Hobby Boss kit, wings and lower fuselage are one integral part, so that some major cutting and PSR were necessary to create a new, “clean” lower fuselage. For the new wings a piece of the cowling in front of the windscreen had to be cut out, the result looks very natural, though, the P.7 wing literally fell into place. The P.7 wings were taken, together with their respective support struts, wholesale from the Mistercraft kit, I just added flaps and lowered them, and I added fairings under the wings for the machine guns – OOB the kit comes with shallow holes that look a bit strange?
The empennage was taken over from the MS.406, but the stabilizers were replaced with the P.7’s, because they were bigger and their shape matches the fin so well. The fixed landing gear is a donor from an ICM Heinkel He 51 floatplane (surplus parts), it was just shortened by about 2mm in order to avoid an exaggerated nose-up stance due to the high propeller position.
The cockpit was taken OOB, just a pilot figure was added to hide the Hobby Boss kit’s rather basic interior.
Painting and markings:
Prototype liveries tend to be dry affairs, and therefore my RWD-24 received a standard pre-WWII livery for Polish aircraft in a uniform brownish-green khaki (”Light Polish Khaki”) over light blue wing undersides. For the very unique khaki tone I used Modelmaster 1711 (FS 34087, a rather yellowish interpretation of this tone), while the wings’ undersides were painted with Humbrol 65 (Aircraft Blue). The khaki tone was - on Polish high wing aircraft of the time - typically carried on the whole fuselage, including the undersides, so I adopted the tone for the complete landing gear and the wing struts, too. For a little more variety, I gave the engine a cowling in a bare metal finish (Humbrol Polished Aluminum Metallizer) and the airframe parts that are covered with fabric were apinted with Humbrol 155 - FS 34087, too, but a morre greenish and darker interpretation of this tone.
The kit received a black ink washing and some post-shading through dry-brushing of single panels with lighter tones. The cockpit interior was painted in a medium grey, the propeller blades became Revell 99 (Aluminum) with red tips, a black spinner and partly blackened back sides (in order to avoid light reflections that could blind the pilot).
Most markings come from a Polish aircraft aftermarket sheet. The red lightning cheatline on the fuselage and on the wings were borrowed from Indonesian MiG-21Fs (from two Begemot sheets). The contrast to the khaki is not strong, but I thought that some decoration would suit a prototype fighter well. The tactical codes consist of single white and black letters (both TL Modellbau stuff).
After some exhaust and gun soot stains the model was finally sealed with matt acrylic varnish, just the metallic cowling and the spinner received a light shine.
While the outcome looks rather unsuspicious, this kitbashing was a lot of work – esp. the landing gear and the cosmetic surgery to remove the MS.406’s lower wings was more demanding than I had thought at first. But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.
Painting and markings:
I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.
A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.
After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.
Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.

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.

Some background:
At the end of WW2, Sweden was in search of a new fighter offering better performance than the J21 could offer. The latter was an indigenous fighter/attack aircraft from SAAB that first took to the air in 1943 and dated back to a requirement from 1941. The J21 was designed as an unusual twin boom pusher configuration, where the propeller was mounted in the rear of the fuselage, pushing the aircraft forward. The advantages of a pusher design were that the view forward was unobstructed and armament could be concentrated in the nose, while the heavy engine was placed close to the center of gravity for better handling and agility. A major drawback was the difficulty in escaping from the aircraft in an emergency, though, as the pilot could get drawn into the propeller blades. SAAB deliberated between systems that would eject the pilot, or jettison the propeller or even the whole engine, via a system of explosive bolts, and eventually installed an early, explosives-powered ejector seat developed by Bofors for this purpose.
However, the SAAB 21 had its share of trouble (overheating an unreliable DB 605 engine), and in 1944 a new requirement for a more powerful and conventional fighter was issued. Selecting the Rolls Royce Griffon as the powerplant, SAAB initially looked into adapting the engine to the J21. However, this proved impractical, so SAAB started work on a clean-sheet design.
The L27, as it was known in the project stage, ended up closely resembling the latest designs to come from Britain like the Supermarine Spitfire or the Martin Baker MB 5, as well as the North American P-51 Mustang. The Griffon engine, chosen for initial development and flight tests, drove a contra-rotating propeller and sat in the nose. Top speed with the Griffon was expected to be around 700 km/h (435 mph). Later production aircraft were to be powered by a domestically developed, new H-24 cylinder motor similar to the British Napier Sabre engine and delivering output in significant excess of 2.200 hp (1.640 kW). With this machine, the aircraft was expected to reach a top speed of 740 km/h (460 mph) or even more.
The wings were similar to those used on the Fairey Firefly, complete with Fairey’s characteristic Youngman flaps, but with small wing root extensions and a thicker profile than the late Spitfires’ wings, and with more rounded wing tips. Similar to the P-51, the L27’s landing gear with a wide track retracted inwards into the wings, and the tail wheel could be fully retracted, too.
Armament, consisting of four 20mm Hispano cannons, was to be concentrated in the wings just outside of the propeller arc, and unlike the Spitfire’s arrangement with underwing coolers, the L27’s single radiator was placed in a ventral tunnel position, very similar to the arrangement on the P-51.
A total of three prototypes were ordered, and the aircraft was now formally designated J27A; two were to be powered by Rolls-Royce Griffon 83 engines, and one as a test structure and earmarked for the development of the 24 cylinder engine and its integration into the projected J27B.
The first flight of a J27A took place in March 1945, and the promising results kept the project evolving until late 1946, when the aircraft was cleared for service and production in January 1947. 70 aircraft with Griffon engines were ordered.
Anyway, in early 1945, SAAB had also launched a project to determine how to provide the J21A with a jet engine to get the experience of jet engines and flying at high speeds. The goal was to catch up with the development of jet aircraft, which were moving ahead fast in England, where, among others, de Havilland already had the de Havilland Vampire in production. The resulting J21R, SAAB's first jet, made its first flight on 10 March 1947 and it marked the death knell for any piston-engine fighter development and use in Sweden. Consequentially the 24 cylinder engine never made it from the drawing board, and after the initial production run of the Griffon-powered J27A was completed until early 1949, further production was stopped and the whole J27 program terminated. Serial production J27As differed only slightly from the prototypes. The most obvious change was a taller vertical stabilizer and a small fin fillet, less obvious was a modified landing gear cover arrangement, because the original design with a single, large cover of the main wheels tended to bulge outward at high speed. A split design mended this problem.
While the J27A’s projected top speed of 700km/h was impressive for a piston-engine fighter and frequently confirmed in service, it was inadequate in the oncoming jet age. In the end, SAAB opted to pursuit jet fighter endeavors that soon led to the very modern and innovative SAAB J29 that soon became Sweden’s standard jet fighter.
In frontline service the J27 was, even though it was popular among its pilots and maintenance crews, almost immediately replaced by jets, at first with the J28B Vampire (from 1951 on), which were in turn quickly replaced in 1952 with the indigenous J29 Tunnan.
The last J27A was, after serving with fighter units primarily in southern Sweden, already retired from frontline duties in 1955. Some aircraft, though, were kept in service as target tugs, liaison aircraft for the air staff and for dissimilar air combat training. The last machine was finally decommissioned in summer 1961.

The kit and its assembly:
This is a “real” what-if model, or at least the attempt to build a phantom aircraft from single parts! The SAAB 27 is a bit of a mystery, because valid information is sparse, especially concerning details about its shape. You find some drawings or profiles, but IMHO these are based on guesswork and rather vague. The J27 is frequently described as a “Swedish Spitfire with a P-51 radiator” or a “Swedish Super-Spitfire”, but that leaves much to be desired, because the similarity is only superficial. Hence, this model here is rather a free interpretation of what a service J27 could have looked like.
For long time I fought with two building options: either convert a Fairey Firefly (Airfix’ Mk. 5 would have been my bet), or use a Spitfire Mk. 22. After long considerations I settled for the latter one, because I feared that the Firefly would result in a rather massive aircraft, and the Airfix kit itself is vintage and worth a building fight on its own.
So I used an Airfix Spitfire Mk. 22, but from this (very nice!) kit just a few things were taken, because I wanted a more individual look. Only the fuselage, cockpit interior and landing gear survived, and I even inserted a 2.5mm wide “wedge plug” around the cockpit and wedge-shaped inserts at the fuselage halves’ seams in order to add some beef to the sleek (if not spindly) Spitfire. I think it’s hard to notice, but the overall proportions look good. At the tail and the front end, the original fuselage width was kept, though.
Reason behind this was the P-51 radiator’s width (leftover from a Matchbox kit) that was considerably wider than the Spitfire fuselage. Furthermore, the thicker/more massive wings from a P-47 (from an early MPM kit) also called for a more massive body.
For the new wings, some adaptations to the Spitfire wing roots had to be made, though, e.g. a bulged mid-wing section under the fuselage. The Thunderbolt parts also had the benefit of wells for a landing gear that retracts inwards. I also used P-47 landing gear parts, even though the struts were shortened at their bases by 3mm and the covers accordingly. For the sake of a different look (the Spitfire wheels are very characteristic) I used different main wheels from a Revell G.91R. The landing gear cover arrangement differs from J27 sketches (as far as I can tell, it must have been similar to the P-51's), but I stuck with the P-47 parts because they match well with the rest of the aircraft.
The contraprop belongs to a late mark Seafire, left over from a Special Hobby kit. The propeller was in so far modified that I added a metal axis and a styrene tube adapter for the fuselage, so that both propeller parts can (theoretically) spin. OOB, the Special Hobby solution is simply to be glued onto the nose, fixed, despite being constructed in two separate parts?
Furthermore, the carburetor intake was changed: the Spitfire’s scoop at the wings’ leading edge was replace by a Firefly-style lip intake right behind the propeller.
The whole tail section was reconditioned, too. Descriptions of the J27’s tail are corny, but “more square than a Spitfire’s”. Instead of simple cosmetic surgery I thoroughly replaced the OOB fin with a Supermarine Attacker’s (Novo kit) with some mods to the outline, which fits well in size and is …more square!
The new tail is a bit taller and has a fin fillet, making it look very P-51-ish, but that’s O.K. for me. At least it’s different from the round Spitfire shape.
I also exchanged the stabilizers, the round Spitfire parts gave way to differently shaped pieces from a Hobby Boss La-7. Their shape is similar to a P-47’s, but they are smaller and match J27 illustrations well.
The canopy was also changed. Through the widened fuselage around the cockpit the tight OOB Spitfire hood would hardly match, anyway. The bubble layout remained, and I adapted a bigger Matchbox P-51 canopy to the new fuselage contours, and moved forward as far as possible.
Painting and markings:
The Swedish Air Force as operator was settled, as well as early post-WWII markings. But I did not want the standard, uniform olive green/blue grey livery, so I painted the upper surfaces with camouflage scheme made from two green tones: a medium green tone (Humbrol 102, Army Green, ~FS 34096) and a bluish, dark green (Humbrol 91, RLM 70 equivalent), applied in bands – somewhat inspired by a scheme carried by some SAAB 32 Lansen in the early 60ies.
The underside was kept in the typical Swedish blue-grey, for which I used Humbrol 87. The waterline was placed very low so that the upper camouflage was also taken to the radiator flanks under the fuselage and wings.
The cockpit was painted in very dark grey (Humbrol 32), while the landing gear and the wells were kept in Aluminum (Humbrol 56).
As a 2nd squadron machine, the code letter became blue, as well as the two-part spinner, latter’s paint was mixed, based on the squadron code letter decal’s tone on the tail.
The roundels and the 'R' codes come from an RBD Studio aftermarket sheet from Sweden, further decals like the yellow ‘9’ code, the squadron’s ‘Bonzo’ dog mascot emblem as well as most stencils come from a Heller SAAB 21.
A complex build, yet the model aircraft looks so innocent… Anyway, the goal was IMHO achieved: this J27 model just looks like a “Swedish Spitfire with a P-51 radiator”, and at first glance you cannot be certain if this is a modified Griffon Spitfire or a P-51D. Both is true, to a certain degree, but also not correct, because the changes are more fundamental and the wings are completely different from either. So, the mission’s been accomplished. ;)
And I feel inclined to tackle a J23, too, a Bf109/P-51B design hybrid that was designed as a conservative alternative to the pusher J21.
Decided to switch out the original shields and give her a lance for a weapon.I might start painting it today?
New pics form an old model.
This is one of (in the meantime...) four major kit conversions - or better: kit-bashings - I did on the basis of 1:100 Bandai Gerwalk Valkyries and leftover pieces from other 1:100 scale Valkyries in Battroid mode, plus material from the junkyard.
These "Super Valkyries" carry rocket boosters for non-atmospherical use, so-called FAST packages ("Fuel And Sensor Trays"). Parts for these extra items were included in some Arii/Bandai VF-1 Gerwalk and Battroid kits. However, there is/was only a single vintage 1:100 Imai kit of an OOB VF-1S Super Valkyrie in Fighter Mode, but it is really crappy and calls for lots of improvements. Therefore I decided to build my own model from scratch.
At the time of making, I just had vague visuals as reference, so some details on this model (it's ~25 years old, even the internet was just nerd stuff at that time and offered only limited content!) are not 100% accurate ;)
The legs were completely re-built through kitbashing: they are modified pieces from a Gerwalk Valkyri,e combined with lower legs from a transformable 1:100 scale kit. The folded arms between the legs are completely improvised, too, made from two lower arm halves and tailored to fit the gap between the bulky new legs.
The big RMS-1 missiles under the wings were made from scratch. These are modified 1.000 lbs. bombs in 1:72 scale from old Matchbox kits, their rear fin arrangement is a simple piece of flexible plastic straw that fits perfectly.
The color scheme was inspired by a VF-1 side profile drawing in the source book "This is animation, Special: MACROSS PLUS", an overall deep blue machine, with a white radar nose and dark grey FAST packs. The look resembles US Navy fighters from the 50ies - and as simple as it is, it looks gorgeous on a VF-1!
I just did not use the authentic blue (FS 15042), which was a bit too murky at the kit's small scale and too greenish for my personal taste. So I rather settled for Humbrol's 15 "Midnight Blue".
The FAST pieces were painted in Humbrol 184 ("Stock Freight Grey"), a very dark tone.
Markings came from the scrap box, the dragon emblem of the fictional SVF-406 fighter squadron (stationed on ARMD-03 in Earth orbit) are insignia of US Marines' VMA-324 attack fighter squadron, which flew A-4 Skyhawks.

Some background:
In the late 1970s the Mikoyan OKB began development of a hypersonic high-altitude reconnaissance aircraft. Designated "Izdeliye 301" (also known as 3.01), the machine had an unusual design, combining a tailless layout with variable geometry wings. The two engines fueled by kerosene were located side by side above the rear fuselage, with the single vertical fin raising above them, not unlike the Tu-22 “Blinder” bomber of that time, but also reminiscent of the US-American SR-71 Mach 3 reconnaissance aircraft.
Only few and rather corny information leaked into the West, and the 301 was believed not only to act as a reconnaissance plane , it was also believed to have (nuclear) bombing capabilities. Despite wind tunnel testing with models, no hardware of the 301 was ever produced - aven though the aircraft could have become a basis for a long-range interceptor that would replace by time the PVO's Tupolew Tu-28P (ASCC code "Fiddler"), a large aircraft armed solely with missiles.
Despite limitations, the Tu-28P served well in its role, but the concept of a very fast interceptor aircraft, lingered on, since the Soviet Union had large areas to defend against aerial intruders, esp. from the North and the East. High speed, coupled with long range and the ability to intercept an incoming target at long distances independently from ground guidance had high priority for the Soviet Air Defence Forces. Even though no official requirement was issued, the concept of Izdeliye 301 from the Seventies was eventually developed further into the fixed-wing "Izdeliye 701" ultra-long-range high-altitude interceptor in the 1980ies.
The impulse for this new approach came when Oleg S. Samoylovich joined the Mikoyan OKB after having worked at Suchoi OKB on the T-60S missile carrier project. Similar in overall design to the former 301, the 701 was primarily intended as a kind of successor for the MiG-31 Foxhound for the 21st century, which just had completed flight tests and was about to enter PVO's front line units.
Being based on a long range cruise missile carrier, the 701 would have been a huge plane, featuring a length of 30-31m, a wing span of 19m (featuring a highly swept double delta wing) and having a maximum TOW of 70 tons! Target performance figures included a top speed of 2.500km/h, a cruising speed of 2.100km/h at 17.000m and an effective range of 7.000km in supersonic or 11.000km in subsonic mode. Eventually, the 701 program was mothballed, too, being too ambitious and expensive for a specialized development that could also have been a fighter version of the Tu-22 bomber!
Anyway, while the MiG-31 was successfully introduced in 1979 and had evolved in into a capable long-range interceptor with a top speed of more than Mach 3 (limited to Mach 2.8 in order to protect the aircraft's structural integrity), MiG OKB decided in 1984 to take further action and to develop a next-generation technology demonstrator, knowing that even the formidable "Foxhound" was only an interim solution on the way to a true "Four plus" of even a 6th generation fighter. Other new threats like low-flying cruise missiles, the USAF's "Project Pluto" or the assumed SR-71 Mach 5 successor “Aurora” kept Soviet military officials on the edge of their seats, too.
Main objective was to expand the Foxhound's state-of the-art performance, and coiple it with modern features like aerodynamic instability, supercruise, stealth features and further development potential.
The aircraft's core mission objectives comprised:
- Provide strategic air defense and surveillance in areas not covered by ground-based air defense systems (incl. guidance of other aircraft with less sophisticated avionics)
- Top speed of Mach 3.2 or more in a dash and cruise at Mach 3.0 for prolonged periods
- Long range/high speed interception of airspace intruders of any kind, including low flying cruise missiles, UAVs and helicopters
- Intercept cruise missiles and their launch aircraft from sea level up to 30.000m altitude by reaching missile launch range in the lowest possible time after departing the loiter area
Because funding was scarce and no official GOR had been issued, the project was taken on as a private venture. The new project was internally known as "Izdeliye 710" or "71.0". It was based on both 301 and 701 layout ideas and the wind tunnel experiences with their unusual layouts, as well as Oleg Samoylovich's experience with the Suchoi T-4 Mach 3 bomber project and the T-60S.
"Izdeliye 710" was from the start intended only as a proof-of-concept prototype, yet fully functional. It would also incorporate new technologies like heat-resistant ceramics against kinetic heating at prolonged high speeds (the airframe had to resist temperatures of 300°C/570°F and more for considerable periods), but with potential for future development into a full-fledged interceptor, penetrator and reconnaissance aircraft.
Overall, “Izdeliye 710" looked like a shrinked version of a mix of both former MiG OKB 301 and 701 designs, limited to the MiG-31's weight class of about 40 tons TOW. Compared with the former designs, the airframe received an aerodynamically more refined, partly blended, slender fuselage that also incorporated mild stealth features like a “clean” underside, softened contours and partly shielded air intakes. Structurally, the airframe's speed limit was set at Mach 3.8.
From the earlier 301 design,the plane retained the variable geometry wing. Despite the system's complexity and weight, this solution was deemed to be the best approach for a combination of a high continuous top speed, extended loiter time in the mission’s patrol areas and good performance on improvised airfields. Minimum sweep was a mere 10°, while, fully swept at 68°, the wings blended into the LERXes. Additional lift was created through the fuselage shape itself, so that aerodynamic surfaces and therefore drag could be reduced.
Pilot and radar operator sat in tandem under a common canopy with rather limited sight. The cockpit was equipped with a modern glass cockpit with LCD screens. The aircraft’s two engines were, again, placed in a large, mutual nacelle on the upper rear fuselage, fed by large air intakes with two-dimensional vertical ramps and a carefully modulated airflow over the aircraft’s dorsal area.
Initially, the 71.0 was to be powered by a pair of Soloviev D-30F6 afterburning turbofans with a dry thrust of 93 kN (20,900 lbf) each, and with 152 kN (34,172 lbf) with full afterburner. These were the same engines that powered the MiG-31, but there were high hopes for the Kolesov NK-101 engine: a variable bypass engine with a maximum thrust in the 200kN range, at the time of the 71.0's design undergoing bench tests and originally developed for the advanced Suchoj T-4MS strike aircraft.
With the D-30F6, the 71.0 was expected to reach Mach 3.2 (making the aircraft capable of effectively intercepting the SR-71), but the NK-101 would offer in pure jet mode a top speed in excess of Mach 3.5 and also improve range and especially loiter time when running as a subsonic turbofan engine.
A single fin with an all-moving top and an additional deep rudder at its base was placed on top of the engine nacelle. Additional maneuverability at lower speed was achieved by retractable, all-moving foreplanes, stowed in narrow slits under the cockpit. Longitudinal stability at high speed was improved through deflectable stabilizers: these were kept horizontal for take-off and added to the overall lift, but they could be folded down by up to 60° in flight, acting additionally as stabilizer strakes.
Due to the aircraft’s slender shape and unique proportions, the 71.0 quickly received the unofficial nickname "жура́вль" (‘Zhurávl' = Crane). The aircaft’s stalky impression was emphasized even more through its unusual landing gear arrangement: Due to the limited internal space for the main landing gear wells between the weapons bay, the wing folding mechanisms and the engine nacelle, MiG OKB decided to incorporate a bicycle landing gear, normally a trademark of Yakovlew OKB designs, but a conventional landing gear could simply not be mounted, or its construction would have become much too heavy and complex.
In order to facilitate operations from improvised airfields and on snow the landing gear featured twin front wheels on a conventional strut and a single four wheel bogie as main wheels. Smaller, single stabilizer wheels were mounted on outriggers that retracted into slender fairings at the wings’ fixed section trailing edge, reminiscent of early Tupolev designs.
All standard air-to-air weaponry, as well as fuel, was to be carried internally. Main armament would be the K-100 missile (in service eventually designated R-100), stored in a large weapons bay behind the cockpit on a rotary mount. The K-100 had been under development at that time at NPO Novator, internally coded ‘Izdeliye 172’. The K-100 missile was an impressive weapon, and specifically designed to attack vital and heavily defended aerial targets like NATO’s AWACS aircraft at BVR distance.
Being 15’ (4.57 m) long and weighing 1.370 lb (620 kg), this huge ultra-long-range weapon had a maximum range of 250 mi (400 km) in a cruise/glide profile and attained a speed of Mach 6 with its solid rocket engine. This range could be boosted even further with a pair of jettisonable ramjets in tubular pods on the missile’s flanks for another 60 mi (100 km). The missile could attack targets ranging in altitude between 15 – 25,000 meters.
The weapon would initially be allocated to a specified target through the launch aircraft’s on-board radar and sent via inertial guidance into the target’s direction. Closing in, the K-100’s Agat 9B-1388 active seeker would identify the target, lock on, and independently attack it, also in coordination with other K-100’s shot at the same target, so that the attack would be coordinated in time and approach directions in order to overload defense and ensure a hit.
The 71.0’s internal mount could hold four of these large missiles, or, alternatively, the same number of the MiG-31’s R-33 AAMs. The mount also had a slot for the storage of additional mid- and short-range missiles for self-defense, e .g. three R-60 or two R-73 AAMs. An internal gun was not considered to be necessary, since the 71.0 or potential derivatives would fight their targets at very long distances and rather rely on a "hit-and-run" tactic, sacrificing dogfight capabilities for long loitering time in stand-by mode, high approach speed and outstanding acceleration and altitude performance.
Anyway, provisions were made to carry a Gsh-301-250 gun pod on a retractable hardpoint in the weapons bay instead of a K-100. Alternatively, such pods could be carried externally on four optional wing root pylons, which were primarily intended for PTB-1500 or PTB-3000 drop tanks, or further missiles - theoretically, a maximum of ten K-100 missiles could be carried, plus a pair of short-range AAMs.
Additionally, a "buddy-to-buffy" IFR set with a retractable drogue (probably the same system as used on the Su-24) was tested (71.2 was outfitted with a retractable refuelling probe in front of the cockpit), as well as the carriage of simple iron bombs or nuclear stores, to be delivered from very high altitudes. Several pallets with cameras and sensors (e .g. a high resolution SLAR) were also envisioned, which could easily replace the missile mounts and the folding weapon bay covers for recce missions.
Since there had been little official support for the project, work on the 710 up to the hardware stage made only little progress, since the MiG-31 already filled the long-range interceptor role in a sufficient fashion and offered further development potential.
A wooden mockup of the cockpit section was presented to PVO and VVS officials in 1989, and airframe work (including tests with composite materials on structural parts, including ceramic tiles for leading edges) were undertaken throughout 1990 and 1991, including test rigs for the engine nacelle and the swing wing mechanism.
Eventually, the collapse of the Soviet Union in 1991 suddenly stopped most of the project work, after two prototype airframes had been completed. Their internal designations were Izdeliye 71.1 and 71.2, respectively. It took a while until the political situation as well as the ex-Soviet Air Force’s status were settled, and work on Izdeliye 710 resumed at a slow pace.
After taking two years to be completed, 71.1 eventually made its roll-out and maiden flight in summer 1994, just when MiG-31 production had ended. MiG OKB still had high hopes in this aircraft, since the MiG-31 would have to be replaced in the next couple of years and "Izdeliye 710" was just in time for the potential procurement process. The first prototype wore a striking all-white livery, with dark grey ceramic tiles on the wings’ leading edges standing out prominently – in this guise and with its futuristic lines the slender aircraft reminded a lot of the American Space Shuttle.
71.1 was primarily intended for engine and flight tests (esp. for the eagerly awaited NK-101 engines), as well as for the development of the envisioned ramjet propulsion system for full-scale production and further development of Izdeliye 710 into a Mach 3+ interceptor. No mission avionics were initially fitted to this plane, but it carried a comprehensive test equipment suite and ballast.
Its sister ship 71.2 flew for the first time in late 1994, wearing a more unpretentious grey/bare metal livery. This plane was earmarked for avionics development and weapons integration, especially as a test bed for the K-100 missile, which shared Izdeliye 710’s fate of being a leftover Soviet project with an uncertain future and an even more corny funding outlook.
Anyway, aircraft 71.2 was from the start equipped with a complete RP-31 ('Zaslon-M') weapon control system, which had been under development at that time as an upgrade for the Russian MiG-31 fleet being part of the radar’s development program secured financial support from the government and allowed the flight tests to continue. The RP-31 possessed a maximum detection range of 400 km (250 mi) against airliner-sized targets at high altitude or 200 km against fighter-sized targets; the typical width of detection along the front was given as 225 km. The system could track 24 airborne targets at one time at a range of 120 km, 6 of which could be simultaneously attacked with missiles.
With these capabilities the RP-31 suite could, coupled with an appropriate carrier airframe, fulfil the originally intended airspace control function and would render a dedicated and highly vulnerable airspace control aircraft (like the Beriev A-50 derivative of the Il-76 transport) more or less obsolete. A group of four aircraft equipped with the 'Zaslon-M' suite would be able to permanently control an area of airspace across a total length of 800–900 km, while having ultra-long range weapons at hand to counter any intrusion into airspace with a quicker reaction time than any ground-based fighter on QRA duty. The 71.0, outfitted with the RP-31/K-100 system, would have posed a serious threat to any aggressor.
In March 1995 both prototypes were eventually transferred to the Kerchenskaya Guards Air Base at Savasleyka in the Oblast Vladimir, 300 km east of Mocsow, where they received tactical codes of '11 Blue' and '12 Blue'. Besides the basic test program and the RP-31/K-100 system tests, both machines were directly evaluated against the MiG-31 and Su-27 fighters by the Air Force's 4th TsBPi PLS, based at the same site.
Both aircraft exceeded expectations, but also fell short in certain aspects. The 71.0’s calculated top speed of Mach 3.2 was achieved during the tests with a top speed of 3,394 km/h (2.108 mph) at 21,000 m (69.000 ft). Top speed at sea level was confirmed at 1.200 km/h (745 mph) indicated airspeed.
Combat radius with full weapon load and internal fuel only was limited to 1,450 km (900 mi) at Mach 0.8 and at an altitude of 10,000 m (33,000 ft), though, and it sank to a mere 720 km (450 mi) at Mach 2.35 and at an altitude of 18,000 m (59,000 ft). Combat range with 4x K-100 internally and 2 drop tanks was settled at 3,000 km (1,860 mi), rising to 5,400 km (3,360 mi) with one in-flight refueling, tested with the 71.2. Endurance at altitude was only slightly above 3 hours, though. Service ceiling was 22,800 m (74,680 ft), 2.000 m higher than the MiG-31.
While these figures were impressive, Soviet officials were not truly convinced: they did not show a significant improvement over the simpler MiG-31. MiG OKB tried to persuade the government into more flight tests and begged for access to the NK-101, but the Soviet Union's collapse halted this project, too, so that both Izdeliye 710 had to keep the Soloviev D-30F6.
Little is known about the Izdeliye 710 project’s progress or further developments. The initial tests lasted until at least 1997, and obviously the updated MiG-31M received official favor instead of a completely new aircraft. The K-100 was also dropped, since the R-33 missile and later its R-37 derivative sufficiently performed in the long-range aerial strike role.
Development on the aircraft as such seemed to have stopped with the advent of modernized Su-27 derivatives and the PAK FA project, resulting in the Suchoi T-50 prototype. Unconfirmed reports suggest that one of the prototypes (probably 71.1) was used in the development of the N014 Pulse-Doppler radar with a passive electronically scanned array antenna in the wake of the MFI program. The N014 was designed with a range of 420 km, detection target of 250km to 1m and able to track 40 targets while able to shoot against 20.
Most interestingly, Izdeliye 710 was never officially presented to the public, but NATO became aware of its development through satellite pictures in the early Nineties and the aircraft consequently received the ASCC reporting codename "Fastback".
Until today, only the two prototypes have been known to exist, and it is assumed – had the type entered service – that the long-range fighter had received the official designation "MiG-41".

The kit and its assembly
The second entry for the 2017 “Soviet” Group Build at whatifmodelers.com – a true Frankenstein creation, based on the scarce information about the real (but never realized) MiG 301 and 701 projects, the Suchoj T-60S, as well as some vague design sketches you can find online and in literature.
This one had been on my project list for years and I already had donor kits stashed away – but the sheer size (where will I leave it once done…?) and potential complexity kept me from tackling it.
The whole thing was an ambitious project and just the unique layout with a massive engine nacelle on top of the slender fuselage instead of an all-in-one design makes these aircraft an interesting topic to build. The GB was a good motivator.
“My” fictional interpretation of the MiG concepts is mainly based on a Dragon B-1B in 1:144 scale (fuselage, wings), a PM Model Su-15 two seater (donating the nose section and the cockpit, as well as wing parts for the fin) and a Kangnam MiG-31 (for the engine pod and some small parts). Another major ingredient is a pair of horizontal stabilizers from a 1:72 Hasegawa A-5 Vigilante.
Fitting the cockpit section took some major surgery and even more putty to blend the parts smoothly together. Another major surgical area was the tail; the "engine box" came to be rather straightforward, using the complete rear fuselage section from the MiG-31 and adding the intakes form the same kit, but mounted horizontally with a vertical splitter.
Blending the thing to the cut-away tail section of the B-1 was quite a task, though, since I not only wanted to add the element to the fuselage, but rather make it look a bit 'organic'. More than putty was necessary, I also had to made some cuts and transplantations. And after six PSR rounds I stopped counting…
The landing gear was built from scratch – the front wheel comes mostly from the MiG-31 kit. The central bogie and its massive leg come from a VEB Plasticart 1:100 Tu-20/95 bomber, plus some additional struts. The outriggers are leftover landing gear struts from a Hobby Boss Fw 190, mated with wheels which I believe come from a 1:200 VEB Plasticart kit, an An-24. Not certain, though. The fairings are slender MiG-21 drop tanks blended into the wing training edge. For the whole landing gear, the covers were improvised with styrene sheet, parts from a plastic straw(!) or leftover bits from the B-1B.
The main landing gear well was well as the weapons’ bay themselves were cut into the B-1B underside and an interior scratched from sheet and various leftover materials – I tried to maximize their space while still leaving enough room for the B-1B kit’s internal VG mechanism.
The large missiles (two were visible fitted and the rotary launcher just visibly hinted at) are, in fact, AGM-78 ‘Standard’ ARMs in a fantasy guise. They look pretty Soviet, though, like big brothers of the already not small R-33 missiles from the MiG-31.
While not in the focus of attention, the cockpit interior is completely new, too – OOB, the Su-15 cockpit only has a floor and rather stubby seats, under a massive single piece canopy. On top of the front wheel well (from a Hasegawa F-4) I added a new floor and added side consoles, scratched from styrene sheet. F-4 dashboards improve the decoration, and I added a pair of Soviet election seats from the scrap box – IIRC left over from two KP MiG-19 kits.
The canopy was taken OOB, I just cut it into five parts for open display. The material’s thickness does not look too bad on this aircraft – after all, it would need a rather sturdy construction when flying at Mach 3+ and withstanding the respective pressures and temperatures.
Painting
As a pure whif, I was free to use a weirdo design - but I rejected this idea quickly. I did not want a garish splinter scheme or a bright “Greenbottle Fly” Su-27 finish.
With the strange layout of the aircraft, the prototype idea was soon settled – and Soviet prototypes tend to look very utilitarian and lusterless, might even be left in grey. Consequently, I adapted a kind of bare look for this one, inspired by the rather shaggy Soviet Tu-22 “Blinder” bombers which carried a mix of bare metal and white and grey panels. With additional black leading edges on the aerodynamic surfaces, this would create a special/provisional but still purposeful look.
For the painting, I used a mix of several metallizer tones from ModelMaster and Humbrol (including Steel, Magnesium, Titanium, as well as matt and polished aluminum, and some Gun Metal and Exhaust around the engine nozzles, partly mixed with a bit of blue) and opaque tones (Humbrol 147 and 127). The “scheme” evolved panel-wise and step by step. The black leading edges were an interim addition, coming as things evolved, and they were painted first with black acrylic paint as a rough foundation and later trimmed with generic black decal stripes (from TL Modellbau). A very convenient and clean solution!
The radomes on nose and tail and other di-electric panels became dark grey (Humbrol 125). The cockpit tub was painted with Soviet Cockpit Teal (from ModelMaster), while the cockpit opening and canopy frames were kept in a more modest medium grey (Revell 57). On the outside of the cabin windows, a fat, deep yellow sealant frame (Humbrol 93, actually “Sand”) was added.
The weapon bay was painted in a yellow-ish primer tone (seen on pics of Tu-160 bombers) while the landing gear wells received a mix of gold and sand; the struts were painted in a mixed color, too, made of Humbrol 56 (Aluminum) and 34 (Flat White). The green wheel discs (Humbrol 131), a typical Soviet detail, stand out well from the rather subdued but not boring aircraft, and they make a nice contrast to the red Stars and the blue tactical code – the only major markings, besides a pair of MiG OKB logos under the cockpit.
Decals were puzzled together from various sheets, and I also added a lot of stencils for a more technical look. In order to enhance the prototype look further I added some photo calibration markings on the nose and the tail, made from scratch.
A massive kitbashing project that I had pushed away for years - but I am happy that I finally tackled it, and the result looks spectacular. The "Firefox" similarity was not intended, but this beast really looks like a movie prop - and who knwos if the Firefox was not inspired by the same projects (the MiG 301 and 701) as my kitbash model?
The background info is a bit lengthy, but there's some good background info concerning the aforementioned projects, and this aircraft - as a weapon system - would have played a very special and complex role, so a lot of explanations are worthwhile - also in order to emphasize that I di not simply try to glue some model parts together, but rather try to spin real world ideas further.
Mighty bird!

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.

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 Northrop Grumman-IAI F-24 is the latest reincarnation of the USAF "Lightweight Fighter Program" which dates back to the 1950ies and started with the development of Northrop's F-5 "Freedom Fighter".
The 1st generation F-5 became very successful in the export market and saw a long line of development, including the much more powerful F-5E "Tiger II" and the F-20 Tigershark (initially called F-5G). Northrop had high hopes for the F-20 in the international market; however, policy changes following Ronald Reagan's election meant the F-20 had to compete for sales against aircraft like the F-16, the USAF's latest fighter design (which was politically favored). The F-20 development program was eventually abandoned in 1986 after three prototypes had been built and a fourth partially completed.
But this was not the end for Northrop’s Lightweight Fighter. In the early 1980s, two X-29As experimental aircraft were built by Grumman from two existing Northrop F-5A Freedom Fighter airframes. The Grumman X-29 was a testbed for forward-swept wings, canard control surfaces, and other novel aircraft technologies. The aerodynamic instability of this arrangement increased agility but required the use of computerized fly-by-wire control. Composite materials were used to control the aeroelastic divergent twisting experienced by forward-swept wings, also reducing the weight. The NASA test program continued from 1984 to 1991 and the X-29s flew 242 times, gathering valuable data and breaking ground for new aerodynamic technologies of 4th and 5th generation fighters.
Even though no service aircraft directly evolved from the X-29, its innovative FBW system as well as the new material technologies also opened the door for an updated F-20 far beyond the 1990ies. It became clear that ever expensive and complex aircraft could not be the answer to modern, asymmetrical warfare in remote corners of the world, with exploding development costs and just a limited number of aircraft in service that could not generate true economies of scale, esp. when their state-of-the-art design would not permit any export.
Anyway, a global market for simpler fighter aircraft was there, as 1st generation F-16s as well as the worldwide, aging F-5E fleet and types of Soviet/Russian origin like the MiG-29 provided the need for a modern, yet light and economical jet fighter. Contemporary types like the Indian HAL Tejas, the Swedish Saab Gripen, the French Dassault Rafale and the Pakistani/Chinese FC-1/JF-17 ”Thunder” proved this trend among 4th - 4.5th generation fighter aircraft.
Northrop Grumman (Northrop bought Grumman in 1994) initiated studies and basic design work on a respective New Lightweight Fighter (NLF) as a private venture in 1995. Work on the NLF started at a slow pace, as the company was busy with re-structuring.
The idea of an updated lightweight fighter was fueled by another source, too: Israel. In 1998 IAI started looking in the USA for a development partner for a new, light fighter that would replace its obsolete Kfir fleet and partly relieve its F-16 and F-15 fleet from interception tasks. The domestic project for that role, the IAI Lavi, had been stillborn, but lots of its avionics and research were still at hand and waited for an airframe for completion.
The new aircraft for the IAF was to be superior to the MiG-29, at least on par with the F-16C/D, but easier to maintain, smaller and overall cheaper. Since the performance profiles appeared to be similar to what Northrop Grumman was developing under the NLF label, the US company eventually teamed up with IAI in 2000 and both started the mutual project "Namer" (=נמר, “Tiger” in Hebrew), which eventually lead to the F-24 I for the IAF which kept its project name for service and to the USAF’s F-24A “Tigershark”.
The F-24, as the NLF, was based on the F-20 airframe, but outwardly showed only little family heritage, onle the forward fuselage around the cockpit reminds of the original F-5 design . Many aerodynamic details, e. g. the air intakes and air ducts, were taken over from the X-29, though, as the experimental aircraft and its components had been developed for extreme maneuvers and extra high agility. Nevertheless, the X-29's forward-swept wing was considered to be too exotic and fragile for a true service aircraft, but the F-24 was to feature an Active Aeroelastic Wing (AAW) system.
AAW Technology integrates wing aerodynamics, controls, and structure to harness and control wing aeroelastic twist at high speeds and dynamic pressures. By using multiple leading and trailing edge controls like "aerodynamic tabs", subtle amounts of aeroelastic twist can be controlled to provide large amounts of wing control power, while minimizing maneuver air loads at high wing strain conditions or aerodynamic drag at low wing strain conditions. This system was initially tested on the X-29 and later on the X-53 research aircraft, a modified F-18, until 2006.
Both USAF and IAF versions feature this state-of-the-art aerodynamic technology, but it is uncertain if other customers will receive it. While details concerning the F-24's system have not been published yet, it is assumed that its AAW is so effective that canard foreplanes could be omitted without sacrificing lift and maneuverability, and that drag is effectively minimized as the wing profile can be adjusted according to the aircraft’s speed, altitude, payload and mission – much like a VG wing, but without its clumsy and heavy swiveling mechanism which has to bear high g forces. As a result, the F-24 is, compared to the F-20, which could carry an external payload of about 3.5 tons, rumored to be able to carry up to 5 tons of ordnance.
The delta wing shape proved to be a perfect choice for the required surface and flap actuators inside of the wings, and it would also offer a very good compromise between lift and drag for a wide range of performance. Anyway, there was one price to pay: in order to keep the wing profile thin and simple, the F-24’s landing gear retracts into the lower fuselage, leaving the aircraft with a relatively narrow track.
Another major design factor for the outstanding performance of this rather small aircraft was weight reduction and structural integrity – combined with simplicity, ruggedness and a modular construction which would allow later upgrades. Instead of “going big” and expensive, the new F-24 was to create its performance through dedicated loss of weight, which was in some part also a compensation for the AAW system in the wings and its periphery.
Weight was saved wherever possible, e .g. a newly developed, lightweight M199A1 gatling gun. This 20mm cannon is a three-barreled, heavily modified version of the already “stripped” M61A2 gun in the USAF’s current F-18E and F-22. One of the novel features is a pneumatic drive instead of the traditional electric mechanism, what not only saves weight but also improves trigger response. The new gun weighs only a mere 65kg (the six-barreled M61A2 weighs 92kg, the original M61A1 112 kg), but still reaches a burst rate of fire of 1.800 RPM (about 800 RPM under cyclic fire, standard practice is to fire the cannon in 30 to 50-round bursts, though) and a muzzle velocity of 1.050 metres per second (3,450 ft/s) with a PGU-28/B round.
While the F-16 was and is still made from 80% aluminum alloys and only from 3% composites, the F-24 makes major use of carbon fiber and other lightweight materials, which make up about 40% of the aircraft’s structure, plus an increased share of Titanium and Magnesium alloys. As a consequence and through many other weight-saving measures like keeping stealth capabilities to a minimum (even though RAM was deliberately used and many details designed to have a natural low radar signature, resulting in modest radar cross-section (RCS) reductions), a single, relatively small engine, a fuel-efficient F404-GE-402 turbofan, is enough to make the F-24 a fast and very agile aircraft, coupled with a good range. The F-24’s thrust/weight ratio is considerably higher than 1, and later versions with a vectored thrust nozzle (see below) will take this level of agility even further – with the pilot becoming the limiting factor for the aircraft’s performance.
USAF and IAF F-24s are outfitted with Northrop Grumman's AN/APG-80 Active Electronically Scanned Array (AESA) radar, also used in the F-16 Block 60 aircraft. Other customers might only receive the AN/APG-68, making the F-24 comparable to the F-16C/D.
The first prototype, the YF-24, flew on 8th of March 2008, followed by two more aircraft plus a static airframe until summer 2010. In early 2011 the USAF placed an initial order of 101 aircraft (probably also to stir export sales – the earlier lightweight fighters from Northrop suffered from the fact that the manufacturer’s country would not use the aircraft in its own forces). These initial aircraft will replace older F-16 in the interceptor role, or free them for fighter bomber tasks. The USN and USMC also showed interest in the aircraft for their aggressor squadrons, for dissimilar air combat training. A two-seater, called the F-24B, is supposed to follow soon, too, and a later version for 2020 onwards, tentatively designated F-24C, is to feature an even stronger F404 engine and a 3D vectoring nozzle.
Israel is going to produce its own version domestically from late 2014 on, which will exclusively be used by the IAF. These aircraft will be outfitted with different avionics, built by Elta in Israel, and cater to national requirements which focus more on multi-purpose service, while the USAF focusses with its F-24A on aerial combat and interception tasks.
International interest for the F-24A is already there: in late 2013 Grumman stated that initial talks have been made with various countries, and potential export candidates from 2015 on are Taiwan, Singapore, Thailand, Finland, Norway, Australia and Japan.

The kit and its assembly:
A spontaneous project. This major kitbash was inspired by fellow user nighthunter at whatifmodelers.com, who came up with a profile of a mashed-up US fighter, created “out of boredom”. The original idea was called F-21C, and it was to be a domestic successor to the IAI Kfirs which had been used by the US as aggressor aircraft in USN and USMC service for a few years.
As a weird(?) coincidence I had many of the necessary ingredients for this fictional aircraft in store, even though some parts and details were later changed. This model here is an interpretation of the original design. The idea was spun further, and the available parts that finally went into the model also had some influence on design and background.
I thank nighthunter for sharing the early ideas, inviting me to take the design to the hardware stage (sort of…) and adapting my feedback into new design sketches, too, which, in return, inspired the model building process.
Well, what went into this thing? To cook up a F-24 à la Dizzyfugu you just need (all in 1:72):
● Fuselage from a Hasegawa X-29, including the cockpit and the landing gear
● Fin and nose cone from an Italeri F-16A
● Inner wings from a (vintage) Hasegawa MiG-21F
● Outer wings from a F-4 (probably a J, Hasegawa or Fujimi)
The wing construction deviates from nighthunter’s original idea. The favorite ingredients would have been F-16XL or simple Mirage III wings, but I found the composite wing to be more attractive and “different”. The big F-16XL wings, despite their benefit of a unique shape, might also have created scale/size problems with a F-20 style fuselage? So I built hybrid wings: The MiG-21 landing gear wells were filled with putty and the F-4 outer wings simply glued onto the MiG inner wing sections, which were simply cut down in span. It sounds like an unlikely combo, but these parts fit together almost perfectly! In order to hide the F-4 origins I modified them to carry wingtip launch rails, though, which were also part of nighthunter’s original design.
The AAW technology detail mentioned in the background came in handy as it explains the complicated wing shape and the fact that the landing gear retracts into the fuselage, not into the wings, which would have been more plausible… Anyway, there’s still room for a simpler export version, with Mirage III or Kfir C.2/7 wings, and maybe canards?
Using the X-29 as basis also made fitting the new wings onto the area-ruled fuselage pretty easy, as I could use the wing root parts from the X-29 to bridge the gap. The original, forward-swept wings were just cut away, and the remains used as consoles for the new hybrid delta wings. Took some SERIOUS putty work, but the result is IMHO fine.
The bigger/square X-29 air intakes were taken over, and they change the look of the aircraft, making it look less F-5-ish than a true F-20 fuselage. For the same reason I kept the large fairing at the fin base, combining it with a bigger F-16 tail, though, as a counter-balance to the new, bigger wings. Again, the F-16 fin was/is part of nighthunter’s idea, so the model stays true to the original concept.
For the same reason I omitted the original X-29 nose, which is rather pointy, sports vanes and a large sensor boom. The F-16 nose was a plausible choice, as the AN/APG-80 is also carried by late Fighting Falcons, and its shape fits well, too.
All around the hull, some small details like radar warning sensors, pitots and air scoops were added. Not really necessary, but such thing add IMHO to the overall impression of such a fictional aircraft beyond the prototype stage.
Cockpit and landing gear were taken OOB, I just added a pilot figure and slightly modified the seat.
The ordnance was puzzled together from the scrap box, the AIM-9Ls come from the same F-4 kit which donated its outer wings, the AIM-120s come from an Italeri NATO weapons kit. The drop tanks belong to an F-16.
Painting and markings:
At first I considered an F-24I in IAF markings, or even a Japanese aircraft, but then reverted to one of nighthunter’s initial, simple ideas: an USAF aircraft in the “Hill II” paint scheme (F-16 style), made up from three shades of gray (FS 36118, 36270 and 36375) with low-viz markings and stencils. Dutch/Turkish NF-5A/Bs in the “Hill II” scheme were used as design benchmarks, too. It’s a simple livery, but on this delta wing aircraft it looks pretty interesting. I used enamels, what I had at hand: Humbrol 127 and 126, and Modelmaster's 1723.
A light black ink wash was applied, in order to em,phasize the engraved panel lines, in contrast to that, panels were manually highlighted through dry-brushed, lighter shades of gray (Humbrol 27, 166 and 167).
“Hill II” also adds to a generic, realistic touch for this whif. Doing an exotic air force thing is rather easy, but creating a convincing whif for a huge military machinery like the USAF’s takes more subtlety, I think.
The cockpit was painted in medium Gray (Dark Gull Grey, FS 36231, Humbrol 140), as well as the radome. The landing gear and the air intakes were painted white. The radome was painted with Revell 47 and dry-brushed with Humbrol 140.
Decals were puzzled together from various USAF aircraft, including sheets from an Airfix F-117, an Italeri F-15E and even an Academy OV-10D.
Tadah: a hardware tribute to an idea, born from boredom - and the aircraft does not look even bad at all? What I wanted to achieve was to make the F-24 neither look like a F-20, nor a Saab Gripen clone, as the latter comes close in overall shape, size and design.

The kit and its assembly:
A spontaneous project. This major kitbash was inspired by fellow user nighthunter at whatifmodelers.com, who came up with a profile of a mashed-up US fighter, created “out of boredom”. The original idea was called F-21C, and it was to be a domestic successor to the IAI Kfirs which had been used by the US as aggressor aircraft in USN and USMC service for a few years.
As a weird(?) coincidence I had many of the necessary ingredients for this fictional aircraft in store, even though some parts and details were later changed. This model here is an interpretation of the original design. The idea was spun further, and the available parts that finally went into the model also had some influence on design and background.
I thank nighthunter for sharing the early ideas, inviting me to take the design to the hardware stage (sort of…) and adapting my feedback into new design sketches, too, which, in return, inspired the model building process.
Well, what went into this thing? To cook up a F-24 à la Dizzyfugu you just need (all in 1:72):
● Fuselage from a Hasegawa X-29, including the cockpit and the landing gear
● Fin and nose cone from an Italeri F-16A
● Inner wings from a (vintage) Hasegawa MiG-21F
● Outer wings from a F-4 (probably a J, Hasegawa or Fujimi)
The wing construction deviates from nighthunter’s original idea. The favorite ingredients would have been F-16XL or simple Mirage III wings, but I found the composite wing to be more attractive and “different”. The big F-16XL wings, despite their benefit of a unique shape, might also have created scale/size problems with a F-20 style fuselage? So I built hybrid wings: The MiG-21 landing gear wells were filled with putty and the F-4 outer wings simply glued onto the MiG inner wing sections, which were simply cut down in span. It sounds like an unlikely combo, but these parts fit together almost perfectly! In order to hide the F-4 origins I modified them to carry wingtip launch rails, though, which were also part of nighthunter’s original design.
The AAW technology detail mentioned in the background came in handy as it explains the complicated wing shape and the fact that the landing gear retracts into the fuselage, not into the wings, which would have been more plausible… Anyway, there’s still room for a simpler export version, with Mirage III or Kfir C.2/7 wings, and maybe canards?
Using the X-29 as basis also made fitting the new wings onto the area-ruled fuselage pretty easy, as I could use the wing root parts from the X-29 to bridge the gap. The original, forward-swept wings were just cut away, and the remains used as consoles for the new hybrid delta wings. Took some SERIOUS putty work, but the result is IMHO fine.
The bigger/square X-29 air intakes were taken over, and they change the look of the aircraft, making it look less F-5-ish than a true F-20 fuselage. For the same reason I kept the large fairing at the fin base, combining it with a bigger F-16 tail, though, as a counter-balance to the new, bigger wings. Again, the F-16 fin was/is part of nighthunter’s idea, so the model stays true to the original concept.
For the same reason I omitted the original X-29 nose, which is rather pointy, sports vanes and a large sensor boom. The F-16 nose was a plausible choice, as the AN/APG-80 is also carried by late Fighting Falcons, and its shape fits well, too.
All around the hull, some small details like radar warning sensors, pitots and air scoops were added. Not really necessary, but such thing add IMHO to the overall impression of such a fictional aircraft beyond the prototype stage.
Cockpit and landing gear were taken OOB, I just added a pilot figure and slightly modified the seat.
The ordnance was puzzled together from the scrap box, the AIM-9Ls come from the same F-4 kit which donated its outer wings, the AIM-120s come from an Italeri NATO weapons kit. The drop tanks belong to an F-16.
Painting and markings:
At first I considered an F-24I in IAF markings, or even a Japanese aircraft, but then reverted to one of nighthunter’s initial, simple ideas: an USAF aircraft in the “Hill II” paint scheme (F-16 style), made up from three shades of gray (FS 36118, 36270 and 36375) with low-viz markings and stencils. Dutch/Turkish NF-5A/Bs in the “Hill II” scheme were used as design benchmarks, too. It’s a simple livery, but on this delta wing aircraft it looks pretty interesting. I used enamels, what I had at hand: Humbrol 127 and 126, and Modelmaster's 1723.
A light black ink wash was applied, in order to em,phasize the engraved panel lines, in contrast to that, panels were manually highlighted through dry-brushed, lighter shades of gray (Humbrol 27, 166 and 167).
“Hill II” also adds to a generic, realistic touch for this whif. Doing an exotic air force thing is rather easy, but creating a convincing whif for a huge military machinery like the USAF’s takes more subtlety, I think.
The cockpit was painted in medium Gray (Dark Gull Grey, FS 36231, Humbrol 140), as well as the radome. The landing gear and the air intakes were painted white. The radome was painted with Revell 47 and dry-brushed with Humbrol 140.
Decals were puzzled together from various USAF aircraft, including sheets from an Airfix F-117, an Italeri F-15E and even an Academy OV-10D.
Tadah: a hardware tribute to an idea, born from boredom - and the aircraft does not look even bad at all? What I wanted to achieve was to make the F-24 neither look like a F-20, nor a Saab Gripen clone, as the latter comes close in overall shape, size and design.

Some background:
The ASTA (Aerospace Technologies of Australia, formerly Government Aircraft Factories) Baza development was started in 1995 when the Royal Australian Air Force was searching for a two-seat training aircraft that would allow the transition from initial training on piston-engined aircraft to jets, and could also be used for weapon training and CAS/reconnaissance duties.
ASTA responded with a low-wing two-turboprop-engined all-metal monoplane with retractable landing gear, capable of operating from unprepared strips when operationally required. The aircraft, internally coded “A-31”, was of conventional, all-metal (mainly duralumin) construction. The unswept cantilever wings have 3° of dihedral and are fitted with slotted trailing-edge flaps.
The A-31 had a tandem cockpit arrangement; the crew of two was seated under the upward opening clamshell canopy on Martin-Baker Mk 6AP6A zero/zero ejection seats and were provided with dual controls.
Armor plating was fitted to protect the crew and engines from hostile ground fire. The aircraft was powered by a pair of Garrett TPE 331 engines, driving sets of three-bladed propellers which were also capable of being used as air brakes.
The A-31 was designed for operations from short, rough airstrips.[The retractable tricycle landing gear, with a single nose wheel and twin main wheels retracting into the engine nacelles, is therefore fitted with low pressure tires to suit operations on rough ground, while the undercarriage legs are tall to give good clearance for underslung weapon loads. The undercarriage, flaps and brakes are operated hydraulically, with no pneumatic systems.
Two JATO rockets can be fitted under the fuselage to allow extra-short take-off. Fuel is fed from two fuselage tanks of combined capacity of 800 L (180 imp gal; 210 US gal) and two self-sealing tanks of 460 L (100 imp gal; 120 US gal) in the wings.
Fixed armament of the A-31 consisted of two 30mm Aden cannons mounted under the cockpits with 200 rounds each. A total of nine hardpoints were fitted for the carriage of external stores such as bombs, rockets or external fuel tanks, with one of 1,000 kg (2,200 lb) capacity mounted under the fuselage and the remaining two pairs of 500 kg (1,100 lb) capacity beneath the wing roots and wings inside of the engine nacelles, and two more pairs of hardpoints outside of the engines for another 500 kg and 227 kg, respectively. Total external weapons load was limited to 6,800 lb (3,085 kg) of weapons, though.
Onboard armaments were aimed by a simple reflector sight, since no all weather/night capabilities were called for – even though provisions were made that external sensors could be carried (e. g. a TISEO or a PAVE Spike pod).
Severe competition arose through the BAe Hawk, though: the Royal Australian Air Force ordered 33 Hawk 127 Lead-in Fighters (LIFs) in June 1997, 12 of which were produced in the UK and 21 in Australia – and this procurement severely hampered the A-31’s progress. The initial plan to build 66 aircraft for domestic use, with prospects for export, e. g. to Sri Lanka, Indonesia or Turkey, was cut down to a mere 32 aircraft which were to be used in conjunction with the Australian Army in the FAC role and against mobile ground targets.
This extended role required an upgrade with additional avionics, an optional forward looking infrared (FLIR) sensor and a laser ranger in an extended nose section, which lead to the Mk. II configuration - effectively, only five machines were produced as Mk.I types, and they were updated to Mk. II configuration even before delivery to the RAAF in August 1999.
Since then, the ASTA A-31 has been used in concunction with RAAF's Pilatus PC-9 and BAe Hawk Mk. 127 trainers. Beyond educational duties the type is also employed for Fleet support to Navy operations and for close air support to Army operations.
The 'Baza' (christened by a small sized bird of prey found in the forests of South Asia and Southeast Asia) has even seen serious military duty and already fired in anger: since August 2007, a detachment of No. 114 Mobile Control and Reporting Unit RAAF has been on active service at Kandahar Airfield in southern Afghanistan, and a constant detachment of six A-31's from RAAF 76 Suqadron has been assigned to armed reconnaissance and protection of approximately 75 personnel deployed with the AN/TPS-77 radar, assigned the responsibility to co-ordinate coalition air operations.

The kit and its assembly:
Like many of my whifs, this was spawned by a project at whatifmodelers.com from fellow user silverwindblade that ran under the handle "COIN aircraft from a Hawk" - and in fact, the BAe Hawk's fuselage with its staggered cockpit and good field of view appears as a good basis for a conversion.
I liked the idea VERY much, and while silverwindblade's work would rather develop into a futuristic canard layout aircraft, I decided to keep the COIN aircraft rather conservative - the FMA 58 'Pucara' from Argentina would be a proper benchmark.
The basis here is the Italeri BAe Hawk Mk. 127 kit which comes with the longer nose and modified wings for the RAAF version, as well as with false decals.
Anyway, I'd only use the fuselage, anything else is implanted, partly from unlikely donation kits! Wings incl. engine nacelles and stablizers come from the vintage box scale (1:166?) Revell Convair R3Y-2 Tradewind flying boat(!), the fin from an Academy OV-10 Bronco.
The landing gear was puzzled together, among other from parts of a 1:200 Concorde, the propellers were scratched.
Biggest mod to the fuselage is the dissection of the air intakes (and their blending with the fuselage) as well as a new tail section where the Adour jet engine's exhaust had been.
Painting and markings:
This model was agood excuse to finally apply an SIOP color scheme, which was originally carried by USAF's strategic bombers like B-52 or FB-111. But what actually inspired me were Australian C-130s - it took some time to figure out that their scheme were the USAF's SIOP colors (FS 34201, 34159 and 34079). But that made the Baza's potential user's choice (and fictional origin) easy.
As a COIN role aircraft I settled on a wraparound scheme. I found a pattern scheme on an USN Aggerssor A-4 Skyhawk that had been painted in SIOP colors, too, and adapted it for the model. Basic colors were Humbrol 31, 84 and 116, good approximations - the result looks odd, but suits the Baza well.
Later, panels were emphasized through dry painting with lighter shades and a light black ink wash was applied.
The landing gear became classic white, the cockpit interior medium gray - nothing fancy.
The markings were improvised - the Italeri Hawk Mk. 127 features RAAF 'roos, but these are printed in black - wrong for the OOB kit, but very welcome on my aircraft. The rest was salvaged from the scrap box, the tactical code A-31-06 created with single letters from TL Modellbau.

Some background:
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym.
They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (Sekcja Lotnicza Koła Mechaników Studentów), where they manufactured their first designs. From 1926 they designed several aircraft alone, in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Polish Air Force’s Okęcie aerodrome, today's Warsaw International Airport.
At first, the RWD team designed and built light sportsplanes. Early designs were built in small series and used in Polish sports aviation, including their debut at the Challenge 1930 international contest. Their next designs performed particularly well in competitions - the RWD-6 won the Challenge 1932 and RWD-9s won the Challenge 1934 international contest. The sportsplane RWD-5 was the lightest plane to fly across the Atlantic in 1933. Three types saw mass production: the RWD-8, which became the Polish Air Force basic trainer, the RWD-13 touring plane and the RWD-14 Czapla reconnaissance plane. Other important designs were the RWD-10 aerobatic plane (1933), RWD-17 aerobatic-trainer plane (1937) and RWD-21 light sport plane (1939). Their most ambitious design that entered the hardware stage and eventually took to flight was the RWD-24, a fighter aircraft. However, World War II prevented further development and serial production of later RWD designs, and also put an end to the RWD construction bureau and its workshops.
The RWD-24 had been designed in response to a requirement for a fighter issued by the Polish Air Force in 1934. RWD responded and built a prototype of mixed materials, heavily influenced by French designs and resources, since Poland had procured several fighter, bomber and reconnaissance aircraft from France during the mid-twenties.
RWD’s design team quickly projected that only a monoplane design would be capable of delivering the desired level of performance sought; other modern features were to include a fully enclosed cockpit, a variable-pitch propeller, and landing flaps. The resulting RWD-24 was a high-wing monoplane of mixed construction, with fabric-covered wooden tail and rudders. The wings were directly attached to the upper fuselage and braced. They consisted of a two-spar duralumin structure, complete with rivetted ribs to both the spars and skin. The exterior of the wing was covered by finely corrugated duralumin sheet, while the slotted ailerons had a fabric covering.
Power came from a water-cooled Hispano-Suiza Y V12 engine – a novelty among Polish fighter designs, which traditionally relied upon radial engines, e.g. the Bristol Mercury and Jupiter, imported as license builds from Czechoslovakia (Skoda). The Hispano-Suiza engine meant a considerable step forward, though, since it increased the output by almost +50%, with appreciable improvements of overall performance that promised to put the RWD-24 on eye level with other contemporary foreign monoplane fighters.
In order to improve performance further, much effort was put into aerodynamic effectiveness, despite a rather conservative structure with bracing struts for the wings and stabilizers. For instance, the ventral radiator could be retracted manually, adapting the frontal area to the engine’s cooling needs. The RWD-24’s landing gear was fixed but covered with aerodynamic fairings and spats.
Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.404 cannon with 60 rounds from a drum magazine, mounted as a “moteur canon” between the cylinder banks and firing through the propeller hub, plus two pairs of 7.92 mm (0.312 in) KM Wz 33 machine guns with 450 RPG in the wings outside of the propeller disc. The prototypes only carried the cannon and a single pair of machine guns, though.
First flown by RWD-founder Jerzy Drzewiecki himself, the first prototype demonstrated the type's favorable flying characteristics from the onset – even though the poor field of view for the pilot ahead and downwards during landing and taxiing was criticized. Another critical point was the retractable radiator; while it allowed a remarkable boost in top speed for short periods, the manual temperature management – esp. during combat situations – turned out to be impractical and an automated solution was requested. The firepower of the 20mm cannon received praise, too, despite its limited ammunition capacity. After 80 hours of test flights, in January 1936, the prototype was delivered with all military equipment fitted to the Polish Air Force at Okęcie aerodrome to participate in service trials, while a second prototype was built in parallel and joined the program in May. It differed from the first RWD-24 through a different tail section, which was covered with a bonded metal/wood material (Plymax) skin fixed to duralumin tubing.
Despite its good handling qualities and impressive performance (the contemporary Polish standard fighter, the PZL P.11, had a top speed of 390 km/h (240 mph, 210 kn), while the RWD-24 surpassed 440 km/h (273 mph, 240 kn) at ideal altitude), both the shape and basic configuration of the RWD-24 were hotly contended, particularly between 'traditional' advocates of biplane aircraft and supporters of 'modern' monoplane with retractable landing gear. The RWD-24 would not satisfy either party, and the high wing layout offered no real development potential, together with the field of view issues. Only a complete redesign of the RWD-24 into a low-wing configuration with a retractable landing gear would have been a viable solution. RWD engineers deemed this task to be feasible, but the Polish Air Force did not want to wait any longer for a new fighter aircraft. In consequence, the RWD-24’s development was officially stopped in early 1938, after only two airframes had been built. In the meantime, RWD had also started work on a dedicated low-wing fighter powered by a 800 hp (597 kW) Gnome-Rhône Mars radial engine, the RWD-25, but until then only a mock-up of this alternative type had been built.
However, the two RWD-24 prototypes remained based at Okęcie and were further tested by both the company and by the Polish Air Force. During these test in 1938, the RWD-24s were, among others, evaluated against a Hawker Hurricane Mk.I and a Dewoitine D.520 that had been delivered to Poland for trials (and eventual sales). In the meantime, driven by rising political tensions and threatened by neighboring Germany, the Polish Air Force had started to follow the idea of importing fully developed monoplane fighters in order to quickly boost the country’s air power and deterrent potential. This eventually led to the procurement of Hawker Hurricanes from Great Britain in 1939. But this decision came too late: the fighters were not delivered before 1 September 1939, when Germany invaded Poland, and the Polish Hurricanes on order were alternatively sent to Turkey instead.
Upon the German invasion the RWD-24 prototypes were, together with most other active Polish combat aircraft, dispersed to secondary airfields and allocated to the so-called Pursuit Brigade, deployed in the Warsaw area, where both served until they became unserviceable after a week, due to their exotic nature. Their fate remains unclear, though, since both machines disappeared. But most likely they were both destroyed within two weeks, like 70% of the Polish Air Force’s aircraft.

The kit and its assembly:
This was a rather spontaneous submission for the “Prototypes” group build at whatifmodelers.com in July 2020, originally spawned by the idea of retrograding a Morane Saulnier MS.406 into a biplane with a fixed landing gear, a kind of French Gloster Gladiator. However, this changed when I found a surplus Mistercraft PZL P.7 kit in the stash, which had been part of a combo deal some time ago. Why not use it for a kitbashing and create a late interwar period Polish fighter prototype from the MS.406…?
The MS.406 fuselage comes from the simple Hobby Boss kit, even though some serious bodywork had to be done in order to make the low wing attachment points and the respective large wing root fairings disappear – on the simple Hobby Boss kit, wings and lower fuselage are one integral part, so that some major cutting and PSR were necessary to create a new, “clean” lower fuselage. For the new wings a piece of the cowling in front of the windscreen had to be cut out, the result looks very natural, though, the P.7 wing literally fell into place. The P.7 wings were taken, together with their respective support struts, wholesale from the Mistercraft kit, I just added flaps and lowered them, and I added fairings under the wings for the machine guns – OOB the kit comes with shallow holes that look a bit strange?
The empennage was taken over from the MS.406, but the stabilizers were replaced with the P.7’s, because they were bigger and their shape matches the fin so well. The fixed landing gear is a donor from an ICM Heinkel He 51 floatplane (surplus parts), it was just shortened by about 2mm in order to avoid an exaggerated nose-up stance due to the high propeller position.
The cockpit was taken OOB, just a pilot figure was added to hide the Hobby Boss kit’s rather basic interior.
Painting and markings:
Prototype liveries tend to be dry affairs, and therefore my RWD-24 received a standard pre-WWII livery for Polish aircraft in a uniform brownish-green khaki (”Light Polish Khaki”) over light blue wing undersides. For the very unique khaki tone I used Modelmaster 1711 (FS 34087, a rather yellowish interpretation of this tone), while the wings’ undersides were painted with Humbrol 65 (Aircraft Blue). The khaki tone was - on Polish high wing aircraft of the time - typically carried on the whole fuselage, including the undersides, so I adopted the tone for the complete landing gear and the wing struts, too. For a little more variety, I gave the engine a cowling in a bare metal finish (Humbrol Polished Aluminum Metallizer) and the airframe parts that are covered with fabric were apinted with Humbrol 155 - FS 34087, too, but a morre greenish and darker interpretation of this tone.
The kit received a black ink washing and some post-shading through dry-brushing of single panels with lighter tones. The cockpit interior was painted in a medium grey, the propeller blades became Revell 99 (Aluminum) with red tips, a black spinner and partly blackened back sides (in order to avoid light reflections that could blind the pilot).
Most markings come from a Polish aircraft aftermarket sheet. The red lightning cheatline on the fuselage and on the wings were borrowed from Indonesian MiG-21Fs (from two Begemot sheets). The contrast to the khaki is not strong, but I thought that some decoration would suit a prototype fighter well. The tactical codes consist of single white and black letters (both TL Modellbau stuff).
After some exhaust and gun soot stains the model was finally sealed with matt acrylic varnish, just the metallic cowling and the spinner received a light shine.
While the outcome looks rather unsuspicious, this kitbashing was a lot of work – esp. the landing gear and the cosmetic surgery to remove the MS.406’s lower wings was more demanding than I had thought at first. But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.

RWD’s design team quickly projected that only a monoplane design would be capable of delivering the desired level of performance sought; other modern features were to include a fully enclosed cockpit, a variable-pitch propeller, and landing flaps. The resulting RWD-24 was a high-wing monoplane of mixed construction, with fabric-covered wooden tail and rudders. The wings were directly attached to the upper fuselage and braced. They consisted of a two-spar duralumin structure, complete with rivetted ribs to both the spars and skin. The exterior of the wing was covered by finely corrugated duralumin sheet, while the slotted ailerons had a fabric covering.
Power came from a water-cooled Hispano-Suiza Y V12 engine – a novelty among Polish fighter designs, which traditionally relied upon radial engines, e.g. the Bristol Mercury and Jupiter, imported as license builds from Czechoslovakia (Skoda). The Hispano-Suiza engine meant a considerable step forward, though, since it increased the output by almost +50%, with appreciable improvements of overall performance that promised to put the RWD-24 on eye level with other contemporary foreign monoplane fighters.
In order to improve performance further, much effort was put into aerodynamic effectiveness, despite a rather conservative structure with bracing struts for the wings and stabilizers. For instance, the ventral radiator could be retracted manually, adapting the frontal area to the engine’s cooling needs. The RWD-24’s landing gear was fixed but covered with aerodynamic fairings and spats.
Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.404 cannon with 60 rounds from a drum magazine, mounted as a “moteur canon” between the cylinder banks and firing through the propeller hub, plus two pairs of 7.92 mm (0.312 in) KM Wz 33 machine guns with 450 RPG in the wings outside of the propeller disc. The prototypes only carried the cannon and a single pair of machine guns, though.
First flown by RWD-founder Jerzy Drzewiecki himself, the first prototype demonstrated the type's favorable flying characteristics from the onset – even though the poor field of view for the pilot ahead and downwards during landing and taxiing was criticized. Another critical point was the retractable radiator; while it allowed a remarkable boost in top speed for short periods, the manual temperature management – esp. during combat situations – turned out to be impractical and an automated solution was requested. The firepower of the 20mm cannon received praise, too, despite its limited ammunition capacity. After 80 hours of test flights, in January 1936, the prototype was delivered with all military equipment fitted to the Polish Air Force at Okęcie aerodrome to participate in service trials, while a second prototype was built in parallel and joined the program in May. It differed from the first RWD-24 through a different tail section, which was covered with a bonded metal/wood material (Plymax) skin fixed to duralumin tubing.
Despite its good handling qualities and impressive performance (the contemporary Polish standard fighter, the PZL P.11, had a top speed of 390 km/h (240 mph, 210 kn), while the RWD-24 surpassed 440 km/h (273 mph, 240 kn) at ideal altitude), both the shape and basic configuration of the RWD-24 were hotly contended, particularly between 'traditional' advocates of biplane aircraft and supporters of 'modern' monoplane with retractable landing gear. The RWD-24 would not satisfy either party, and the high wing layout offered no real development potential, together with the field of view issues. Only a complete redesign of the RWD-24 into a low-wing configuration with a retractable landing gear would have been a viable solution. RWD engineers deemed this task to be feasible, but the Polish Air Force did not want to wait any longer for a new fighter aircraft. In consequence, the RWD-24’s development was officially stopped in early 1938, after only two airframes had been built. In the meantime, RWD had also started work on a dedicated low-wing fighter powered by a 800 hp (597 kW) Gnome-Rhône Mars radial engine, the RWD-25, but until then only a mock-up of this alternative type had been built.
However, the two RWD-24 prototypes remained based at Okęcie and were further tested by both the company and by the Polish Air Force. During these test in 1938, the RWD-24s were, among others, evaluated against a Hawker Hurricane Mk.I and a Dewoitine D.520 that had been delivered to Poland for trials (and eventual sales). In the meantime, driven by rising political tensions and threatened by neighboring Germany, the Polish Air Force had started to follow the idea of importing fully developed monoplane fighters in order to quickly boost the country’s air power and deterrent potential. This eventually led to the procurement of Hawker Hurricanes from Great Britain in 1939. But this decision came too late: the fighters were not delivered before 1 September 1939, when Germany invaded Poland, and the Polish Hurricanes on order were alternatively sent to Turkey instead.
Upon the German invasion the RWD-24 prototypes were, together with most other active Polish combat aircraft, dispersed to secondary airfields and allocated to the so-called Pursuit Brigade, deployed in the Warsaw area, where both served until they became unserviceable after a week, due to their exotic nature. Their fate remains unclear, though, since both machines disappeared. But most likely they were both destroyed within two weeks, like 70% of the Polish Air Force’s aircraft.

The kit and its assembly:
This was a rather spontaneous submission for the “Prototypes” group build at whatifmodelers.com in July 2020, originally spawned by the idea of retrograding a Morane Saulnier MS.406 into a biplane with a fixed landing gear, a kind of French Gloster Gladiator. However, this changed when I found a surplus Mistercraft PZL P.7 kit in the stash, which had been part of a combo deal some time ago. Why not use it for a kitbashing and create a late interwar period Polish fighter prototype from the MS.406…?
The MS.406 fuselage comes from the simple Hobby Boss kit, even though some serious bodywork had to be done in order to make the low wing attachment points and the respective large wing root fairings disappear – on the simple Hobby Boss kit, wings and lower fuselage are one integral part, so that some major cutting and PSR were necessary to create a new, “clean” lower fuselage. For the new wings a piece of the cowling in front of the windscreen had to be cut out, the result looks very natural, though, the P.7 wing literally fell into place. The P.7 wings were taken, together with their respective support struts, wholesale from the Mistercraft kit, I just added flaps and lowered them, and I added fairings under the wings for the machine guns – OOB the kit comes with shallow holes that look a bit strange?
The empennage was taken over from the MS.406, but the stabilizers were replaced with the P.7’s, because they were bigger and their shape matches the fin so well. The fixed landing gear is a donor from an ICM Heinkel He 51 floatplane (surplus parts), it was just shortened by about 2mm in order to avoid an exaggerated nose-up stance due to the high propeller position.
The cockpit was taken OOB, just a pilot figure was added to hide the Hobby Boss kit’s rather basic interior.
Painting and markings:
Prototype liveries tend to be dry affairs, and therefore my RWD-24 received a standard pre-WWII livery for Polish aircraft in a uniform brownish-green khaki (”Light Polish Khaki”) over light blue wing undersides. For the very unique khaki tone I used Modelmaster 1711 (FS 34087, a rather yellowish interpretation of this tone), while the wings’ undersides were painted with Humbrol 65 (Aircraft Blue). The khaki tone was - on Polish high wing aircraft of the time - typically carried on the whole fuselage, including the undersides, so I adopted the tone for the complete landing gear and the wing struts, too. For a little more variety, I gave the engine a cowling in a bare metal finish (Humbrol Polished Aluminum Metallizer) and the airframe parts that are covered with fabric were apinted with Humbrol 155 - FS 34087, too, but a morre greenish and darker interpretation of this tone.
The kit received a black ink washing and some post-shading through dry-brushing of single panels with lighter tones. The cockpit interior was painted in a medium grey, the propeller blades became Revell 99 (Aluminum) with red tips, a black spinner and partly blackened back sides (in order to avoid light reflections that could blind the pilot).
Most markings come from a Polish aircraft aftermarket sheet. The red lightning cheatline on the fuselage and on the wings were borrowed from Indonesian MiG-21Fs (from two Begemot sheets). The contrast to the khaki is not strong, but I thought that some decoration would suit a prototype fighter well. The tactical codes consist of single white and black letters (both TL Modellbau stuff).
After some exhaust and gun soot stains the model was finally sealed with matt acrylic varnish, just the metallic cowling and the spinner received a light shine.
While the outcome looks rather unsuspicious, this kitbashing was a lot of work – esp. the landing gear and the cosmetic surgery to remove the MS.406’s lower wings was more demanding than I had thought at first. But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.

Some Background:
During the 1950s, Hindustan Aircraft Limited (HAL) had developed and produced several types of trainer aircraft, such as the HAL HT-2. However, elements within the firm were eager to expand into the then-new realm of supersonic fighter aircraft. Around the same time, the Indian government was in the process of formulating a new Air Staff Requirement for a Mach 2-capable combat aircraft to equip the Indian Air Force (IAF). However, as HAL lacked the necessary experience in both developing and manufacturing frontline combat fighters, it was clear that external guidance would be invaluable; this assistance was embodied by Kurt Tank.
In 1956, HAL formally began design work on the supersonic fighter project. The Indian government, led by Jawaharlal Nehru, authorized the development of the aircraft, stating that it would aid in the development of a modern aircraft industry in India. The first phase of the project sought to develop an airframe suitable for travelling at supersonic speeds, and able to effectively perform combat missions as a fighter aircraft, while the second phase sought to domestically design and produce an engine capable of propelling the aircraft. Early on, there was an explicit adherence to satisfying the IAF's requirements for a capable fighter bomber; attributes such as a twin-engine configuration and a speed of Mach 1.4 to 1.5 were quickly emphasized, and this led to the HF-24 Marut.
On 24 June 1961, the first prototype Marut conducted its maiden flight. It was powered by the same Bristol Siddeley Orpheus 703 turbojets that had powered the Folland Gnat, also being manufactured by HAL at that time. On 1 April 1967, the first production Marut was delivered to the IAF. While originally intended only as an interim measure during testing, HAL decided to power production Maruts with a pair of unreheated Orpheus 703s, meaning the aircraft could not attain supersonic speed. Although originally conceived to operate around Mach 2 the Marut in fact was barely capable of reaching Mach 1 due to the lack of suitably powerful engines.
The IAF were reluctant to procure a fighter aircraft only marginally superior to its existing fleet of British-built Hawker Hunters. However, in 1961, the Indian Government decided to procure the Marut, nevertheless, but only 147 aircraft, including 18 two-seat trainers, were completed out of a planned 214. Just after the decision to build the lukewarm Marut, the development of a more advanced aircraft with the desired supersonic performance was initiated.
This enterprise started star-crossed, though: after the Indian Government conducted its first nuclear tests at Pokhran, international pressure prevented the import of better engines of Western origin, or at times, even spares for the Orpheus engines, so that the Marut never realized its full potential due to insufficient power, and it was relatively obsolescent by the time it reached production.
Due to these restrictions India looked for other sources for supersonic aircraft and eventually settled upon the MiG-21 F-13 from the Soviet Union, which entered service in 1964. While fast and agile, the Fishbed was only a short-range daylight interceptor. It lacked proper range for escort missions and air space patrols, and it had no radar that enabled it to conduct all-weather interceptions. To fill this operational gap, the new indigenous HF-26 project was launched around the same time.
For the nascent Indian aircraft industry, HF-26 had a demanding requirements specification: the aircraft was to achieve Mach 2 top speed at high altitude and carry a radar with a guided missile armament that allowed interceptions in any weather, day and night. The powerplant question was left open, but it was clear from the start that a Soviet engine would be needed, since an indigenous development of a suitable powerplant would take much too long and block vital resources, and western alternatives were out of reach. The mission profile and the performance requirements quickly defined the planned aircraft’s layout: To fit a radar, the air intakes with movable ramps to feed the engines were placed on the fuselage flanks. To make sure the aircraft would fulfill its high-performance demands, it was right from the outset powered by two engines, and it was decided to give it delta wings, a popular design among high-speed aircraft of the time – exemplified by the highly successful Dassault Mirage III (which was to be delivered to Pakistan in 1967). With two engines, the HF-26 would be a heavier aircraft than the Mirage III, though, and it was planned to operate the aircraft from semi-prepared airfields, so that it would receive a robust landing gear with low-pressure tires and a brake parachute.
In 1962 India was able to negotiate the delivery of Tumansky RD-9 turbojet engines from the Soviet Union, even though no afterburner was part of the deal – this had to be indigenously developed by Hindustan Aeronautics Limited (HAL). However, this meant that the afterburner could be tailored to the HF-26, and this task would provide HAL with valuable engineering experience, too.
Now knowing the powerplant, HAL created a single-seater airframe around it, a rather robust design that superficially reminded of the French Mirage III, but there were fundamental differences. The HF-26 had boxy air intakes with movable ramps to control the airflow to the two engines and a relatively wide fuselage to hold them and most of the fuel in tanks between the air ducts behind the cockpit. The aircraft had a single swept fin and a rather small mid-positioned delta-wing with a 60° sweep. The pilot sat under a tight canopy that offered - similar to the Mirage III - only limited all-round vision.
The HF-26's conical nose radome covered an antenna for a ‘Garud’ interception radar – which was in fact a downgraded Soviet ‘Oryol' (Eagle; NATO reporting name 'Skip Spin') system that guided the HF-26’s main armament, a pair of semi-active radar homing (SARH) ‚Saanp’ missiles.
The Saanp missile was developed specifically for the HF-26 in India but used many components of Soviet origin, too, so that they were compatible with the radar. In performance, the Saanp was comparable with the French Matra R.530 air-to-air missile, even though the aerodynamic layout was reversed, with steering fins at the front end, right behind the SARH seaker head - overall the missile reminded of an enlarged AIM-4 Falcon. The missile weighed 180 kg and had a length of 3.5 m. Power came from a two-stage solid rocket that offered a maximum thrust of 80 kN for 2.7 s during the launch phase plus 6.5 s cruise. Maximum speed was Mach 2.7 and operational range was 1.5 to 20 km (0.9 to 12.5 miles). Two of these missiles could be carried on the main wing hardpoints in front of the landing gear wells. Alternatively, infrared-guided R-3 (AA-2 ‘Atoll’) short-range AAMs could be carried by the HF-26, too, and typically two of these were carried on the outer underwing hardpoints, which were plumbed to accept drop tanks (typically supersonic PTB-490s that were carried by the IAF's MiG-21s, too) . Initially, no internal gun was envisioned, as the HF-26 was supposed to be a pure high-speed/high-altitude interceptor that would not engage in dogfights. Two more hardpoints under the fuselage were plumbed, too, for a total of six external stations.
Due to its wing planform, the HF-26 was soon aptly called “Teer” (= Arrow), and with Soviet help the first prototype was rolled out in early 1964 and presented to the public. The first flight, however, would take place almost a year later in January 1965, due to many technical problems, and these were soon complemented by aerodynamic problems. The original delta-winged HF-26 had poor take-off and landing characteristics, and directional stability was weak, too. While a second prototype was under construction in April 1965 the first aircraft was lost after it had entered a spin from which the pilot could not escape – the aircraft crashed and its pilot was killed during the attempt to eject.
After this loss HAL investigated an enlarged fin and a modified wing design with deeper wingtips with lower sweep, which increased wing area and improved low speed handling, too. Furthermore, the fuselage shape had to be modified, too, to reduce supersonic drag, and a more pronounced area ruling was introduced. The indigenous afterburner for the RD-9 engines was unstable and troublesome, too.
It took until 1968 and three more flying prototypes (plus two static airframes) to refine the Teer for serial production service introduction. In this highly modified form, the aircraft was re-designated HF-26M and the first machines were delivered to IAF No. 3 Squadron in late 1969. However, it would take several months until a fully operational status could be achieved. By that time, it was already clear that the Teer, much like the HF-24 Marut before, could not live up to its expectations and was at the brink of becoming obsolete as it entered service. The RD-9 was not a modern engine anymore, and despite its indigenous afterburner – which turned out not only to be chronically unreliable but also to be very thirsty when engaged – the Teer had a disappointing performance: The fighter only achieved a top speed of Mach 1.6 at full power, and with full external load it hardly broke the wall of sound in level flight. Its main armament, the Saanp AAM, also turned out to be unreliable even under ideal conditions.
However, the HF-26M came just in time to take part in the Indo-Pakistani War of 1971 and was, despite its weaknesses, extensively used – even though not necessarily in its intended role. High-flying slow bombers were not fielded during the conflict, and the Teer remained, despite its on-board radar, heavily dependent on ground control interception (GCI) to vector its pilot onto targets coming in at medium and even low altitude. The HF-26M had no capability against low-flying aircraft either, so that pilots had to engage incoming, low-flying enemy aircraft after visual identification – a task the IAF’s nimble MiG-21s were much better suited for. Escorts and air cover missions for fighter-bombers were flown, too, but the HF-26M’s limited range only made it a suitable companion for the equally short-legged Su-7s. The IAF Canberras were frequently deployed on longer range missions, but the HF-26Ms simply could not follow them all the time; for a sufficient range the Teer had to carry four drop tanks, what increased drag and only left the outer pair of underwing hardpoints (which were not plumbed) free for a pair of AA-2 missiles. With the imminent danger of aerial close range combat, though, During the conflict with Pakistan, most HF-26M's were retrofitted with rear-view mirrors in their canopies to improve the pilot's field of view, and a passive IR sensor was added in a small fairing under the nose to improve the aircraft's all-weather capabilities and avoid active radar emissions that would warn potential prey too early.
The lack of an internal gun turned out to be another great weakness of the Teer, and this was only lightly mended through the use of external gun pods. Two of these cigar-shaped pods that resembled the Soviet UPK-23 pod could be carried on the two ventral pylons, and each contained a 23 mm Gryazev-Shipunov GSh-23L autocannon of Soviet origin with 200 rounds. Technically these pods were very similar to the conformal GP-9 pods carried by the IAF MiG-21FLs. While the gun pods considerably improved the HF-26M’s firepower and versatility, the pods were draggy, blocked valuable hardpoints (from extra fuel) and their recoil tended to damage the pylons as well as the underlying aircraft structure, so that they were only commissioned to be used in an emergency.
However, beyond air-to-air weapons, the HF-26M could also carry ordnance of up to 1.000 kg (2.207 lb) on the ventral and inner wing hardpoints and up to 500 kg (1.100 lb) on the other pair of wing hardpoints, including iron bombs and/or unguided missile pods. However, the limited field of view from the cockpit over the radome as well as the relatively high wing loading did not recommend the aircraft for ground attack missions – even though these frequently happened during the conflict with Pakistan. For these tactical missions, many HF-26Ms lost their original overall natural metal finish and instead received camouflage paint schemes on squadron level, resulting in individual and sometimes even spectacular liveries. Most notable examples were the Teer fighters of No. 1 Squadron (The Tigers), which sported various camouflage adaptations of the unit’s eponym.
Despite its many deficiencies, the HF-26M became heavily involved in the Indo-Pakistan conflict. As the Indian Army tightened its grip in East Pakistan, the Indian Air Force continued with its attacks against Pakistan as the campaign developed into a series of daylight anti-airfield, anti-radar, and close-support attacks by fighter jets, with night attacks against airfields and strategic targets by Canberras and An-12s, while Pakistan responded with similar night attacks with its B-57s and C-130s.
The PAF deployed its F-6s mainly on defensive combat air patrol missions over their own bases, leaving the PAF unable to conduct effective offensive operations. Sporadic raids by the IAF continued against PAF forward air bases in Pakistan until the end of the war, and interdiction and close-support operations were maintained. One of the most successful air raids by India into West Pakistan happened on 8 December 1971, when Indian Hunter aircraft from the Pathankot-based 20 Squadron, attacked the Pakistani base in Murid and destroyed 5 F-86 aircraft on the ground.
The PAF played a more limited role in the operations, even though they were reinforced by Mirages from an unidentified Middle Eastern ally (whose identity remains unknown). The IAF was able to conduct a wide range of missions – troop support; air combat; deep penetration strikes; para-dropping behind enemy lines; feints to draw enemy fighters away from the actual target; bombing and reconnaissance. India flew 1,978 sorties in the East and about 4,000 in Pakistan, while the PAF flew about 30 and 2,840 at the respective fronts. More than 80 percent of IAF sorties were close-support and interdiction and about 45 IAF aircraft were lost, including three HF-26Ms. Pakistan lost 60 to 75 aircraft, not including any F-86s, Mirage IIIs, or the six Jordanian F-104s which failed to return to their donors. The imbalance in air losses was explained by the IAF's considerably higher sortie rate and its emphasis on ground-attack missions. The PAF, which was solely focused on air combat, was reluctant to oppose these massive attacks and rather took refuge at Iranian air bases or in concrete bunkers, refusing to offer fights and respective losses.
After the war, the HF-26M was officially regarded as outdated, and as license production of the improved MiG-21FL (designated HAL Type 77 and nicknamed “Trishul” = Trident) and later of the MiG-21M (HAL Type 88) was organized in India, the aircraft were quickly retired from frontline units. They kept on serving into the Eighties, though, but now restricted to their original interceptor role. Beyond the upgrades from the Indo-Pakistani War, only a few upgrades were made. For instance, the new R-60 AAM was introduced to the HF-26M and around 1978 small (but fixed) canards were retrofitted to the air intakes behind the cockpit that improved the Teer’s poor slow speed control and high landing speed as well as the aircraft’s overall maneuverability.
A radar upgrade, together with the introduction of better air-to-ai missiles with a higher range and look down/shoot down capability was considered but never carried out. Furthermore, the idea of a true HF-26 2nd generation variant, powered by a pair of Tumansky R-11F-300 afterburner jet engines (from the license-built MiG-21FLs), was dropped, too – even though this powerplant eventually promised to fulfill the Teer’s design promise of Mach 2 top speed. A total of only 82 HF-26s (including thirteen two-seat trainers with a lengthened fuselage and reduced fuel capacity, plus eight prototypes) were built. The last aircraft were retired from IAF service in 1988 and replaced with Mirage 2000 fighters procured from France that were armed with the Matra Super 530 AAM.

The kit and its assembly:
This whiffy delta-wing fighter was inspired when I recently sliced up a PM Model Su-15 kit for my side-by-side-engine BAC Lightning build. At an early stage of the conversion, I held the Su-15 fuselage with its molded delta wings in my hand and wondered if a shortened tail section (as well as a shorter overall fuselage to keep proportions balanced) could make a delta-wing jet fighter from the Flagon base? Only a hardware experiment could yield an answer, and since the Su-15’s overall outlines look a bit retro I settled at an early stage on India as potential designer and operator, as “the thing the HF-24 Marut never was”.
True to the initial idea, work started on the tail, and I chopped off the fuselage behind the wings’ trailing edge. Some PSR was necessary to blend the separate exhaust section into the fuselage, which had to be reduced in depth through wedges that I cut out under the wings trailing edge, plus some good amount of glue and sheer force the bend the section a bit upwards. The PM Model's jet exhausts were drilled open, and I added afterburner dummies inside - anything would look better than the bleak vertical walls inside after only 2-3 mm! The original fin was omitted, because it was a bit too large for the new, smaller aircraft and its shape reminded a lot of the Suchoj heavy fighter family. It was replaced with a Mirage III/V fin, left over from a (crappy!) Pioneer 2 IAI Nesher kit.
Once the rear section was complete, I had to adjust the front end - and here the kitbashing started. First, I chopped off the cockpit section in front of the molded air intake - the Su-15’s long radome and the cockpit on top of the fuselage did not work anymore. As a remedy I remembered another Su-15 conversion I did a (long) while ago: I created a model of a planned ground attack derivative, the T-58Sh, and, as a part of the extensive body work, I transplanted the slanted nose from an academy MiG-27 between the air intakes – a stunt that was relatively easy and which appreciably lowered the cockpit position. For the HF-26M I did something similar, I just transplanted a cockpit from a Hasegawa/Academy MiG-23 with its ogival radome that size-wise better matched with the rest of the leftover Su-15 airframe.
The MiG-23 cockpit matched perfectly with the Su-15's front end, just the spinal area behind the cockpit had to be raised/re-sculpted to blend the parts smoothly together. For a different look from the Su-15 ancestry I also transplanted the front sections of the MiG-23 air intakes with their shorter ramps. Some mods had to be made to the Su-15 intake stubs, but the MiG-23 intakes were an almost perfect fit in size and shape and easy to integrate into the modified front hill. The result looks very natural!
However, when the fuselage was complete, I found that the nose appeared to be a bit too long, leaving the whole new hull with the wings somewhat off balance. As a remedy I decided at a rather late stage to shorten the nose and took out a 6 mm section in front of the cockpit - a stunt I had not planned, but sometimes you can judge things only after certain work stages. Some serious PSR was necessary to re-adjust the conical nose shape, which now looked more Mirage III-ish than planned!
The cockpit was taken mostly OOB, I just replaced the ejection seat and gave it a trigger handle made from thin wire. With the basic airframe complete it was time for details. The PM Model Su-15s massive and rather crude main landing gear was replaced with something more delicate from the scrap box, even though I retained the main wheels. The front landing gear was taken wholesale from the MiG-23, but had to be shortened for a proper stance.
A display holder adapter was integrated into the belly for the flight scenes, hidden well between the ventral ordnance.
The hardpoints, including missile launch rails, came from the MiG-23; the pylons had to be adjusted to match the Su-15's wing profile shape, the Anab missiles lost their tail sections to create the fictional Indian 'Saanp' AAMs. The R-3s on the outer stations were left over from a MP MiG-21. The ventral pylons belong to Academy MiG-23/27s, one came from the donor kit, the other was found in the spares box. The PTB-490 drop tanks also came from a KP MiG-21 (or one of its many reincarnations, not certain).
Painting and markings:
The paint scheme for this fictional aircraft was largely inspired by a picture of a whiffy and very attractive Saab 37 Viggen (an 1:72 Airfix kit) in IAF colors, apparently a model from a contest. BTW, India actually considered buying the Viggen for its Air Force!
IAF aircraft were and are known for their exotic and sometimes gawdy paint schemes, and with IAF MiG-21 “C 992” there’s even a very popular (yet obscure) aircraft that sported literal tiger stripes. The IAF Viggen model was surely inspired by this real aircraft, and I adopted something similar for my HF-26M.
IAF 1 Squadron was therefore settled, and for the paint scheme I opted for a "stripish" scheme, but not as "tigeresque" as "C 992". I found a suitable benchmark in a recent Libyian MiG-21, which carried a very disruptive two-tone grey scheme. I adapted this pattern to the HA-26M airframe and replaced its colors, similar to the IAF Viggen model, which became a greenish sand tone (a mix of Humbrol 121 with some 159; I later found out that I could have used Humbrol 83 from the beginning, though...) and a very dark olive drab (Humbrol 66, which looks like a dull dark brown in contrast with the sand tone), with bluish grey (Humbrol 247) undersides. With the large delta wings, this turned out to look very good and even effective!
For that special "Indian touch" I gave the aircraft a high-contrast fin in a design that I had seen on a real camouflaged IAF MiG-21bis: an overall dark green base with a broad, red vertical stripe which was also the shield for the fin flash and the aircraft's tactical code (on the original bare metal). The fin was first painted in green (Humbrol 2), the red stripe was created with orange-red decal sheet material. Similar material was also used to create the bare metal field for the tactical code, the yellow bars on the splitter plates and for the thin white canopy sealing.
After basic painting was done the model received an overall black ink washing, post-panel shading and extensive dry-brushing with aluminum and iron for a rather worn look.
The missiles became classic white, while the drop tanks, as a contrast to the camouflaged belly, were left in bare metal.
Decals/markings came primarily from a Begemot MiG-25 kit, the tactical codes on the fin and under the wings originally belong to an RAF post-WWII Spitfire, just the first serial letter was omitted. Stencils are few and they came from various sources. A compromise is the unit badge on the fin: I needed a tiger motif, and the only suitable option I found was the tiger head emblem on a white disc from RAF No. 74 Squadron, from the Matchbox BAC Lightning F.6&F.2A kit. It fits stylistically well, though. ;-)
Finally, the model was sealed with matt acrylic varnish (except for the black radome, which became a bit glossy) and finally assembled.
A spontaneous build, and the last one that I completed in 2022. However, despite a vague design plan the model evolved as it grew. Bashing the primitive PM Model Su-15 with the Academy MiG-23 parts was easier than expected, though, and the resulting fictional aircraft looks sturdy but quite believable - even though it appears to me like the unexpected child of a Mirage III/F-4 Phantom II intercourse, or like a juvenile CF-105 Arrow, just with mid-wings? Nevertheless, the disruptive paint scheme suits the delta wing fighter well, and the green/red fin is a striking contrast - it's a colorful model, but not garish.

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

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

Some Background:
The Lockheed F-94 Starfire was a first-generation jet aircraft of the United States Air Force. It was developed from the twin-seat Lockheed T-33 Shooting Star in the late 1940s as an all-weather, day/night interceptor.
The aircraft reached operational service in May 1950 with Air Defense Command, replacing the propeller-driven North American F-82 Twin Mustang in the all-weather interceptor role. The F-94 was the first operational USAF fighter equipped with an afterburner and was the first jet-powered all-weather fighter to enter combat during the Korean War in January 1953.
The initial production model was the F-94A, which entered operational service in May 1950. Its armament consisted of four 0.50 in (12.7 mm) M3 Browning machine guns mounted in the fuselage with the muzzles exiting under the radome. Two 165 US Gallon (1,204 litre) drop tanks, as carried by the F-80 and T-33, were carried on the wingtips. Alternatively, these could be replaced by a pair of 1,000 lb (454 kg) bombs under the wings, giving the aircraft a secondary fighter bomber capability. 109 were produced.
The subsequent F-94B, which entered service in January 1951, was outwardly virtually identical to the F-94A. The Allison J33 turbojet had a number of modifications made, though, which made it a very reliable engine. The pilot was provided with a more roomy cockpit and the canopy was replaced by a canopy with a bow frame in the center between the two crew members, as well as a new Instrument Landing System (ILS). 356 of these were built.
The following F-94C was extensively modified and initially designated F-97, but it was ultimately decided to treat it as a new version of the F-94. USAF interest was lukewarm, since aircraft technology developed at a fast pace in the Fifties, so Lockheed funded development themselves, converting two F-94B airframes to YF-94C prototypes for evaluation.
To improve performance, a completely new, much thinner wing was fitted, along with a swept tail surface. The J33 engine was replaced with a more powerful Pratt & Whitney J48, a license-built version of the afterburning Rolls-Royce Tay, which produced a dry thrust of 6,350 pounds-force (28.2 kN) and approximately 8,750 pounds-force (38.9 kN) with afterburning.
The fire control system was upgraded to the Hughes E-5 with an AN/APG-40 radar in a modified nose with an enlarged radome. The guns were removed and replaced with an all-rocket armament, which was – at that time – regarded as more effective against high-flying, subsonic bomber formations. The internal armament consisted of four flip-up panels in a ring around the nose, each containing six rockets. External pods on the wings augmented the offensive ordnance to 48 projectiles. Operational service began with six squadrons by May 1954.
According to test pilot Tony LeVier, the F-94C was capable of supersonic flight, but Lockheed felt that the straight wing limited the airframe's potential, esp. with the uprated engine. Besides, the earlier F-94 variants already saw the end of their relatively brief operational life, already being replaced in the mid-1950s by the Northrop F-89 Scorpion and North American F-86D Sabre interceptor aircraft in front-line service and relegated to National Guard service. Therefore, Lockheed launched another update program for the F-94 in 1953, again as a private venture.
The resulting F-94E (the F-94D was a proposed fighter bomber variant which made it to prototype staus) was another, evolutionary modification of the basic concept, which, in the meantime, had almost nothing left in common with its F-80/T-33 ancestry.
It was based on the F-94C, most obvious change was the introduction of swept wings for supersonic capability in level flight. This change also necessitated other aerodynamic adjustments, including a new, deeper fin with increased area and a modified landing gear that would better cope with the increased AUW.
Under the hood, the F-94E was constructed around the new Hughes MG-3 fire control system, similar to the early F-102, but kept the AN/APG-40, even though it was coupled with an enlarged antenna. The respective new radome now covered the complete nose cross section. Furthermore, the F-94 E introduced innovations like a Texas Instruments infrared search/tracking system (IRST), which allowed passive tracking of heat emissions, mounted in a canoe fairing under the nose, passive radar warning receivers, transponders as well as backup artificial horizons.
With this improved equipment the interceptor was now able to deploy semi-active radar homing GAR-1s and/or infrared GAR-2s (later re-designated AIM-4A/B Falcon), operating at day and night as well as under harsh weather conditions.
All missiles were carried externally on underwing pylons. Beside the original main wet hardpoints outside the landing gear (typically a pair of 165 US Gallon (1,204 litre) drop tank, that were carried on the wing tips on the former versions), two additional pairs of lighter pylons were added under the wing roots and the outer wings.
Typically, a pair of SARH- and IR-guided AIM-4s were carried, one per pylon, plus a pair of drop tanks. Alternatively, the F-94E could carry up to 4.000 lb (1,816 kg) of ordnance, including up to six streamlined pods, each holding nineteen 2 ¾” in (70 mm) Mk 4/Mk 40 Folding-Fin Aerial Rockets. Any internal armament was deleted.
The F-94E's new wings allowed a top speed of 687mph at sea level and a top speed of 693 mph (1,115 km/h) at height – compared with the F-94C’s 640 mph (556 kn, 1,030 km/h) a rather mild improvement. But the enlarged wing area resulted in a considerably improved rate of climb as well as good maneuverability at height. The F-94E's performance was overall on par with the F-86D, with the benefit of a second crew member, while its weapon capability was comparable with the much bigger (but slower) F-89.
Both of these types were already introduced, so the Air Force's interest was, once more, less than enthusiastic. Eventually the F-94's proven resilience to harsh climate conditions, esp. in the Far North, earned Lockheed in 1955 a production contract for 72 F-94Es for interceptor squadrons based in Alaska, New Foundland, Greenland and Iceland.
These production machines arrived to the Northern theatre of operations in summer 1956 and featured an improved weapon capability: on the wet wing hardpoints, a pair of MB-1 Genie (formerly known as ‘Ding Dong’ missile, later re-coded AIR-2) nuclear unguided rockets could be carried.
For the missile pylons under the wing roots, twin launch rails were introduced so that the F-94E could theoretically carry a total of up to eight AIM-4 missiles, even though the wet pylons were typically occupied with the drop tanks and only two pairs of AIM-4A and B were carried under the wing roots. The J48 engine was slightly uprated, too: the F-94E’s P-9 variant delivered now 6,650 lbf (29.5 kN) dry thrust and 10,640 lbf (47.3 kN) at full afterburner.
Keflavik Airport, Iceland, although controlled by Military Air Transport Service (MATS), was the first base to be equipped with F-94Es as part of the 82d Fighter-Interceptor Squadron in early 1957, where the machines replaced F-94Bs and F-89Cs.
The type was popular among the crews, because it coupled a relatively high agility (compared with the F-89 Scorpion) with the psychological benefit of a two men crew, not to be underestimated during operations in the Far North as well as over open water.
The F-94's career didn't last long, though, the aircraft soon became outdated. The last F-94E was already retired from USAF front-line service in November 1962, only three years after the last F-94C Starfires were phased out of ANG service. Eventually, the fighters were replaced by the F-101, F-102 and the F-106.

The kit and its assembly:
Another entry for the Cold War GB at whatifmodelers.com. This build was originally inspired by profiles of a P-80/F-86 hybrid, and respective kitbashings from other modelers. An elegant, though fictional, aircraft! Nevertheless, I wanted to build one, too, and take the original idea a step further. So I chose the F-94 as an ingredient for the kit mix – a rather overlooked aircraft, and getting hands on a donation kit took some time, since there are not many options.
I wanted to use the F-94C as starting point, which is already considerably different from the F-80/T-33. Adding swept wings (from a Hobby Boss F-86F, with larger “6-3” wings) changed this look even more. So much that I decided to modify the fin, which did not look appropriate anymore.
The fin and the spine’s rear end was replaced with the fin of a Kangnam/Revell Yak-38. In order to unify shapes and make the donation less obvious, the Yak-38 fin’s characteristic, pointed tip was clipped and replaced by a more conventional design, scratched from a piece of 1.5mm styrene sheet. In the wake of this modification, the round elevator tips were clipped, too.
Using the F-94’s landing gear wells as benchmarks, the F-86 wings (which had to be cut off of the Hobby Boss kit’s integral, lower fuselage part) were sanded into shape and simply glued into a proper position.
This worked so well that a completely new and plausible main landing gear installation was created. As a consequence, I used the F-86’s landing gear struts - they are much better detailed than the Emhar F-94C’s parts. The front wheel strut (it’s a single piece) was transplanted too, even though the suspension was switched 180°.
The Emhar F-94C’s cockpit is pretty good (esp. the seats) and were taken OOB. I just covered some gaps in the cockpit walls and under the windscreen with paper tissue, soaked with white glue.
The nose was replaced by a bigger radome, taken from an Armstrong Whitworth Meteor NF.14 (Matchbox kit). Its diameter and shape fit almost perfectly onto the F-94C’s front end, and the result reminds a lot of the EF-94C photo reconnaissance test aircraft! Under the nose, a shallow fairing for the IR sensor was added, and all four air brakes were mounted in open position.
The underwing pylons come from the scrap box (one pair from an Airfix A-1 Skyraider, another from an ESCI Kamow Ka-34 ‘Hokum’ which also provide the launch rails for the ordnance). The drop tanks come probably from an Italeri F-16 (not certain) while the four AIM-4s come from a Hasegawa USAF air-to-air weapons set.
Painting and markings:
This was supposed to become a classic USAF aircraft of the late Fifties, since the F-94 had never been exported. I was actually tempted to add Red Stars, though, because the overall shape has a certain Soviet look to it - esp. the nose, which reminds a lot of the contemporary Yak-25 interceptor?
But the original USAF idea won, with an all-metal finish. In order to brighten things up I chose a squadron that served with the Northeast or Alaskan Air Command, which added orange-red high-viz markings to wings and fuselage.
The NMF sections were primed with a base coat of Revell’s acrylic Aluminum. On top of that, single panels and details were painted with Alu Plate and Steel Metallizer from Modelmaster.
The International Orange markings were created with Humbrol 132, slightly shaded with orange (Humbrol 18).
Part of the nose section and the spine were painted in ADC Grey (FS 16473, Modelmaster), just for some diversity. Cockpit interior and landing gear wells received a coat of US Cockpit Green (Humbrol 226), while the interior of the air brakes was painted in Zinc Primer (Humbrol 81), according to pictures of operational F-94s.
The landing gear struts and the inside of their covers became Aluminum (Humbrol 56). The anti glare panel in front of the cockpit was done with dark olive drab (Humbrol 66), the radome flat black and weathered with wet-in-wet streaks of sand brown.
Operational F-94s show serious weathering on their di-electric noses, so this detail was taken over to the kit. Other weathering with paint, beyond a basic black ink wash and some shading on the orange areas, was not done.
The drop tanks were painted with Steel Metallizer, for a different metallic shade from the fuselage, and the AIM-4’s received a typical outfit in white and bright red with different seeker heads.
Primary decals come from a Heller F-94B kit, which have the benefit of a silver background – even though this does not match 100% with the paint. Squadron markings come from an Xtradecal F-102 sheet, tailored to the kit. Most stencils come from the Emhar OOB sheet, plus some more from the aforementioned F-102 sheet.
After some soot stains around the exhaust were added with graphite, the kit was sealed under a coat of semi-glossy acrylic varnish. The anti glare panel and the radome were kept matt, though.
A pretty result. Mixing parts from a Shooting Star and a Sabre (a Shooting Sabre, perhaps?) results in a very elegant aircraft. And while the F-94 lost much of its original, elegant appeal, the combo still works with this later interceptor variant of the F-80. Very plausible, IMHO.

Some background:
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym.
They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (Sekcja Lotnicza Koła Mechaników Studentów), where they manufactured their first designs. From 1926 they designed several aircraft alone, in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Polish Air Force’s Okęcie aerodrome, today's Warsaw International Airport.
At first, the RWD team designed and built light sportsplanes. Early designs were built in small series and used in Polish sports aviation, including their debut at the Challenge 1930 international contest. Their next designs performed particularly well in competitions - the RWD-6 won the Challenge 1932 and RWD-9s won the Challenge 1934 international contest. The sportsplane RWD-5 was the lightest plane to fly across the Atlantic in 1933. Three types saw mass production: the RWD-8, which became the Polish Air Force basic trainer, the RWD-13 touring plane and the RWD-14 Czapla reconnaissance plane. Other important designs were the RWD-10 aerobatic plane (1933), RWD-17 aerobatic-trainer plane (1937) and RWD-21 light sport plane (1939). Their most ambitious design that entered the hardware stage and eventually took to flight was the RWD-24, a fighter aircraft. However, World War II prevented further development and serial production of later RWD designs, and also put an end to the RWD construction bureau and its workshops.
The RWD-24 had been designed in response to a requirement for a fighter issued by the Polish Air Force in 1934. RWD responded and built a prototype of mixed materials, heavily influenced by French designs and resources, since Poland had procured several fighter, bomber and reconnaissance aircraft from France during the mid-twenties.
RWD’s design team quickly projected that only a monoplane design would be capable of delivering the desired level of performance sought; other modern features were to include a fully enclosed cockpit, a variable-pitch propeller, and landing flaps. The resulting RWD-24 was a high-wing monoplane of mixed construction, with fabric-covered wooden tail and rudders. The wings were directly attached to the upper fuselage and braced. They consisted of a two-spar duralumin structure, complete with rivetted ribs to both the spars and skin. The exterior of the wing was covered by finely corrugated duralumin sheet, while the slotted ailerons had a fabric covering.
Power came from a water-cooled Hispano-Suiza Y V12 engine – a novelty among Polish fighter designs, which traditionally relied upon radial engines, e.g. the Bristol Mercury and Jupiter, imported as license builds from Czechoslovakia (Skoda). The Hispano-Suiza engine meant a considerable step forward, though, since it increased the output by almost +50%, with appreciable improvements of overall performance that promised to put the RWD-24 on eye level with other contemporary foreign monoplane fighters.
In order to improve performance further, much effort was put into aerodynamic effectiveness, despite a rather conservative structure with bracing struts for the wings and stabilizers. For instance, the ventral radiator could be retracted manually, adapting the frontal area to the engine’s cooling needs. The RWD-24’s landing gear was fixed but covered with aerodynamic fairings and spats.
Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.404 cannon with 60 rounds from a drum magazine, mounted as a “moteur canon” between the cylinder banks and firing through the propeller hub, plus two pairs of 7.92 mm (0.312 in) KM Wz 33 machine guns with 450 RPG in the wings outside of the propeller disc. The prototypes only carried the cannon and a single pair of machine guns, though.
First flown by RWD-founder Jerzy Drzewiecki himself, the first prototype demonstrated the type's favorable flying characteristics from the onset – even though the poor field of view for the pilot ahead and downwards during landing and taxiing was criticized. Another critical point was the retractable radiator; while it allowed a remarkable boost in top speed for short periods, the manual temperature management – esp. during combat situations – turned out to be impractical and an automated solution was requested. The firepower of the 20mm cannon received praise, too, despite its limited ammunition capacity. After 80 hours of test flights, in January 1936, the prototype was delivered with all military equipment fitted to the Polish Air Force at Okęcie aerodrome to participate in service trials, while a second prototype was built in parallel and joined the program in May. It differed from the first RWD-24 through a different tail section, which was covered with a bonded metal/wood material (Plymax) skin fixed to duralumin tubing.
Despite its good handling qualities and impressive performance (the contemporary Polish standard fighter, the PZL P.11, had a top speed of 390 km/h (240 mph, 210 kn), while the RWD-24 surpassed 440 km/h (273 mph, 240 kn) at ideal altitude), both the shape and basic configuration of the RWD-24 were hotly contended, particularly between 'traditional' advocates of biplane aircraft and supporters of 'modern' monoplane with retractable landing gear. The RWD-24 would not satisfy either party, and the high wing layout offered no real development potential, together with the field of view issues. Only a complete redesign of the RWD-24 into a low-wing configuration with a retractable landing gear would have been a viable solution. RWD engineers deemed this task to be feasible, but the Polish Air Force did not want to wait any longer for a new fighter aircraft. In consequence, the RWD-24’s development was officially stopped in early 1938, after only two airframes had been built. In the meantime, RWD had also started work on a dedicated low-wing fighter powered by a 800 hp (597 kW) Gnome-Rhône Mars radial engine, the RWD-25, but until then only a mock-up of this alternative type had been built.
However, the two RWD-24 prototypes remained based at Okęcie and were further tested by both the company and by the Polish Air Force. During these test in 1938, the RWD-24s were, among others, evaluated against a Hawker Hurricane Mk.I and a Dewoitine D.520 that had been delivered to Poland for trials (and eventual sales). In the meantime, driven by rising political tensions and threatened by neighboring Germany, the Polish Air Force had started to follow the idea of importing fully developed monoplane fighters in order to quickly boost the country’s air power and deterrent potential. This eventually led to the procurement of Hawker Hurricanes from Great Britain in 1939. But this decision came too late: the fighters were not delivered before 1 September 1939, when Germany invaded Poland, and the Polish Hurricanes on order were alternatively sent to Turkey instead.
Upon the German invasion the RWD-24 prototypes were, together with most other active Polish combat aircraft, dispersed to secondary airfields and allocated to the so-called Pursuit Brigade, deployed in the Warsaw area, where both served until they became unserviceable after a week, due to their exotic nature. Their fate remains unclear, though, since both machines disappeared. But most likely they were both destroyed within two weeks, like 70% of the Polish Air Force’s aircraft.

The kit and its assembly:
This was a rather spontaneous submission for the “Prototypes” group build at whatifmodelers.com in July 2020, originally spawned by the idea of retrograding a Morane Saulnier MS.406 into a biplane with a fixed landing gear, a kind of French Gloster Gladiator. However, this changed when I found a surplus Mistercraft PZL P.7 kit in the stash, which had been part of a combo deal some time ago. Why not use it for a kitbashing and create a late interwar period Polish fighter prototype from the MS.406…?
The MS.406 fuselage comes from the simple Hobby Boss kit, even though some serious bodywork had to be done in order to make the low wing attachment points and the respective large wing root fairings disappear – on the simple Hobby Boss kit, wings and lower fuselage are one integral part, so that some major cutting and PSR were necessary to create a new, “clean” lower fuselage. For the new wings a piece of the cowling in front of the windscreen had to be cut out, the result looks very natural, though, the P.7 wing literally fell into place. The P.7 wings were taken, together with their respective support struts, wholesale from the Mistercraft kit, I just added flaps and lowered them, and I added fairings under the wings for the machine guns – OOB the kit comes with shallow holes that look a bit strange?
The empennage was taken over from the MS.406, but the stabilizers were replaced with the P.7’s, because they were bigger and their shape matches the fin so well. The fixed landing gear is a donor from an ICM Heinkel He 51 floatplane (surplus parts), it was just shortened by about 2mm in order to avoid an exaggerated nose-up stance due to the high propeller position.
The cockpit was taken OOB, just a pilot figure was added to hide the Hobby Boss kit’s rather basic interior.
Painting and markings:
Prototype liveries tend to be dry affairs, and therefore my RWD-24 received a standard pre-WWII livery for Polish aircraft in a uniform brownish-green khaki (”Light Polish Khaki”) over light blue wing undersides. For the very unique khaki tone I used Modelmaster 1711 (FS 34087, a rather yellowish interpretation of this tone), while the wings’ undersides were painted with Humbrol 65 (Aircraft Blue). The khaki tone was - on Polish high wing aircraft of the time - typically carried on the whole fuselage, including the undersides, so I adopted the tone for the complete landing gear and the wing struts, too. For a little more variety, I gave the engine a cowling in a bare metal finish (Humbrol Polished Aluminum Metallizer) and the airframe parts that are covered with fabric were apinted with Humbrol 155 - FS 34087, too, but a morre greenish and darker interpretation of this tone.
The kit received a black ink washing and some post-shading through dry-brushing of single panels with lighter tones. The cockpit interior was painted in a medium grey, the propeller blades became Revell 99 (Aluminum) with red tips, a black spinner and partly blackened back sides (in order to avoid light reflections that could blind the pilot).
Most markings come from a Polish aircraft aftermarket sheet. The red lightning cheatline on the fuselage and on the wings were borrowed from Indonesian MiG-21Fs (from two Begemot sheets). The contrast to the khaki is not strong, but I thought that some decoration would suit a prototype fighter well. The tactical codes consist of single white and black letters (both TL Modellbau stuff).
After some exhaust and gun soot stains the model was finally sealed with matt acrylic varnish, just the metallic cowling and the spinner received a light shine.
While the outcome looks rather unsuspicious, this kitbashing was a lot of work – esp. the landing gear and the cosmetic surgery to remove the MS.406’s lower wings was more demanding than I had thought at first. But the fictional RWD-24 looks very conclusive, a wild mix between outdated and modern features, so typical for many interwar designs. And the Polish colors and markings suit the model well, too.

Some background
The Dassault/Dornier Alpha Jet is a light attack jet and advanced trainer aircraft co-manufactured by Dornier of Germany and Dassault-Breguet of France. In the early 1960s, European air forces began to consider their requirements for the coming decades. One of the results was the emergence of a new generation of jet trainers. The British and French began a collaboration on development of what was supposed to be a supersonic jet aircraft in two versions: trainer and light attack aircraft. The result of this collaboration, the SEPECAT Jaguar, proved to be an excellent aircraft, but its definition had changed in the interim, and the type emerged as a full-sized, nuclear-capable strike fighter, which two-seat variants were used for operational conversion to the type, not for the general training.
This left the original requirement unfulfilled and so the French began discussions with West Germany for collaboration. A joint specification was produced in 1968. The trainer was now subsonic, supersonic trainers having proven something of a dead end. A joint development and production agreement was signed in July 1969 which indicated that the two nations would buy 200 machines, each assembled in their own country.
The Luftwaffe decided to use the Alpha Jet mainly in the light strike role, preferring to continue flight training in the United States on American trainer types instead of performing training in cloudy and crowded Germany. The first production German Alpha Jet performed its maiden flight on 12 April 1978, with deliveries beginning in March 1979. This version was designated the Alpha Jet A (the "A" standing for Appui Tactique or "Tactical Strike") or Alpha Jet Close Support variant. The Luftwaffe obtained 175 machines up to 1983, with the type replacing the Fiat G91R/3. Manufacture of Alpha Jet subassemblies was divided between France and Germany, with plants in each country performing final assembly and checkout. The different avionics fit made French and German Alpha Jets easy to tell apart, with French machines featuring a rounded-off nose and German machines featuring a sharp, pointed nose.
Even though the Alpha Jet A was suitable in the ground attack role and had even been tested in aerial combat against helicopters in 1979, the German Luftwaffe decided in the mid-80ies that – facing the Cold War threat from the east – a more powerful but still economic plane for the close attack role, esp. against hardened ground targets and attack helicopters like the Mi-24 would be needed. Even though such "Alternate Close Support" versions of the Alpha Jet were available at that time, even though these were modified two-seaters. Such planes were bought by Cameroon and Egypt, but from the German Luftwaffe a specialized, more capable plane with a higher strike and survival potential was requested.
In 1986, Dornier developed a respective specialized version, called the Alpha Jet C (for "combat"). This plane was heavily modified, optimized for the ground attack role. It featured a new, single-seated nose section with an armoured cockpit in a much higher position than on the original two-seater. The Alpha jet C version's prominent, pointed nose quickly gave it among its test pilots the nickname "Nasenbär" (Coati).
The new space was used for avionics and an internal Oerlikon 35mm cannon – a variant of the same cannon used in the Gepard anti aircraft tank, firing armour piercing shells with a muzzle velocity of 1,440 m/s (4,700 ft/s) and a range of 5.500m. Avionics includecd SAGEM ULISS 81 INS, a Thomson-CSF VE-110 HUD, a TMV630 laser rangefinder in a modified nose and a TRT AHV 9 radio altimeter, with all avionics linked through a digital databus.
New wings were developed, with a thicker profile and less sweep, and non-jettisonable wing tip tanks as well as two more weapon hardpoints (for a total of six, plus one under the fuselage) added. The landing gear was reinforced for a higher TOW and operation on improvised runways. Fuselage and tail externally looked much the same as the original Alpha Jet A, but internally most structures were reinforced and technical modules placed in new positions.
The C version was from the start powered by two more powerful Larzac 04-C20 turbofans which would also be used in an update for the Luftwaffe’s Alpha Jet As. The hydraulic system was doubled, so that both engines could run separately, and kevlar and titanium armour plating added to vital areas around the lower hull.
The first prototype 98+52 made its maiden flight at Friedrichshafen on 1st of June 1988. It was officially allocated to the JaboG 43 in Oldenburg, but actually spent almost all the time at the Luftwaffe’s Waffentechnische Dienststelle (Flight test center) WTD 61 in Manching near Munich, where it underwent a thorough testing program. More than once the prototype was transferred to Beja, Portugal, for weapon tests and training, as well as direct comparison with the standard Alpha Jet A and other NATO planes. A second airframe was built in 1987 but only used for static tests, system integration and finally damage resilience tests, after which it was written off and scrapped.
While the Alpha Jet C showed high agility at low level and a high survival potential in a hostile battlefield environment, the prototype remained a one-off. In the end, the German Luftwaffe did not want to add another type to its arsenal, despite its similarity with the standard Alpha Jet. Export chances for such a specialized, yet light aircraft were considered as low, since modified Alpha Jet versions were already available and other planes like the AMX or BAe Hawk offered more versatility, and were simply more up to date.
Hence, further development was stopped in September 1989, also under the influence of political changes and the breakdown of the Eastern Block. Even though 98+52 was kept at Manching as a test aircraft for various tasks, the plane was eventually lost in a crash due to hydraulic failure on 3rd of March 1993 – the pilot escaped safely, but 98+52 totally written off.

The kit and its assembly
Yes, another whif, and a modern type, too. The idea came when I found a pair of vintage wings from a vintage Matchbox BAC Strikemaster in good shape and thought "Well, where could these fit...?" Being a fan of the Su-25 I considered building something similar from scratch und using these 30 year old parts.
The Alpha Jet has a basically similar layout, and the wings would match in size. Then, the "new" plane should become a dedicated single-seater, not simply a two-seater with a covered rear cockpit. Browsing through the kit stack I found a A-4F from Revell, and its nose section turned out to be an almost perfect fit for the Alpha Jet fuselage (the vintage Heller kit).
Fitting these parts together required some major surgery and putty work, but the result looks quite convincing. Other additions are a Matchbox pilot figure and some cockpit details, a nose cone from a Fiat G.91 R/3 as an integral laser rangefinder housing, the Strikemaster wings, a modified landing gear (main wheels from the Skyhawk, front wheel from an IAI Kfir) and the armament in the form of the gun, seven hardpoints and the mixed ordnance from the German Luftwaffe arsenal - everything collected from the junkyard.
Painting
While German Luftwaffe machines can look rather boring, various camouflage trials have been conducted during the 80ies and 90ies for the F-4F, Alpha Jet and Tornado fleet. Esp. Phantom IIs saw extensive experiments for air superiority and ground attack paint schemes - and these schemes carried inofficial names like "Milchkuh" (Dairy Cow), "Polizeimühle" (Police Jalopy) or "Disco Bomber".
The whiffy Alpha Jet was a nice opportunity to incorporate one of these experimental schemes, and I settled for something which was applied to F-4F '37+07' and inofficially dubbed "Wolkenmaus" (Cloud Mouse). The Alpha Jet is a good subject, since its stepped side structure with engine nacelles and its spine tunnel is similar to the Phantom II, so that the cammo concept could be easily copied.
Anyway, the authentic "Wolkenmaus" colours are supposed to be (and what I used on the kit)...
On the upper sides:
● RAL 6014 Gelboliv (~FS 34087; Olive Drab, Testors 1711)
● RAL 7012 Basaltgrau (~FS 36152; Humbrol 27)
● RAL 9005 Tiefschwarz, even though I rather believe it to be RAL 7021 Schwarzgrau (darker than FS 36081; Humbrol 182)
Flanks::
● Mix of 2/3 RAL 7035 Lichtgrau + 1/3 RAL 7000 Fehgrau (~FS36473; Aircraft Grey, Testors 1731)
Undersides:
● Mix of 5/6 RAL 7035 Lichtgrau + 1/6 RAL 7000 Fehgrau (~RLM 63; Lichtgrau, Testors 2077)
The tones are just approximations, since I did not want to get original tones just for one project. Hey, it's just a model kit!
The landing gear and its wells were painted in aluminum, the respective covers' inside with Humbrol 81 (Olive Yellow) in a primer finish for some contrast. Cockpit interior as well as the air intakes were kept in in Light Gull Grey (FS 36640, Humbrol 129). The complex paint scheme was applied, as per usual, by brush and hand. The kit received a light black ink wash and some dry painting with lighter tones - the model was not supposed to look dirty, only a bit used.
Decals were scrapped together. JaboG 43 emblems and warning signs were taken from the original Heller decal sheet. The national insignia were taken from a Revell PAH-2 kit, the registration '98+52' was puzzled together with single digits from an aftermarket decal sheet from TL Modellbau. AFAIK, '98+52' has not been used yet by the Luftwaffe, which designates its test aircraft in the 98+XX and 99+XX range. A "true" and active Alpha Jet would have received a 40+XX or 41+XX.
Finally, everything was sealed under a water-based/acryllic matte coat - the Testors colours proved to be very touchy to the Humbrol varnish I normally use.
In the end, I achieved what I wanted, even though not truly perfect. But the kit looks like an 'analogue' Su-25, and actually the whiffy Alpha Jet C reminds much of the pre-Su-25 concepts: the SPB and subsequent LSSh/T-8 attack aircraft?

Some background:
The Hawker Cyclone was an evolutionary successor to the successful Hawker Typhoon and Tempest fighters and fighter-bombers of the Second World War. The Cyclone's design process was initiated in September 1942 by Sydney Camm, one of Hawker's foremost aircraft designers, to meet the Royal Air Force’s requirement for a lightweight Tempest Mk.II and V replacement.
The project, tentatively designated Tempest Mk. VIII, was formalised in January 1943 when the Air Ministry issued Specification F.2/42 around the "Tempest Light Fighter".This was followed up by Specification F.2/43, issued in May 1943, which required a high rate of climb of not less than 4,500 ft/min (23 m/s) from ground level to 20,000 feet (6,096 m), good fighting manoeu rability and a maximum speed of at least 450 mph (724 km/h) at 22,000 feet (6,705 m). The armament was to be four 20mm Hispano V cannon with a total capacity of 600 rounds, plus the capability of carrying two bombs each up to 1,000 pounds (454 kg). In April 1943, Hawker had also received Specification N.7/43 from the Admiralty, who sought a navalized version of the developing aircraft, what eventually led to the Hawker Sea Fury, which was a completely new aircraft, which only shared the general outlines of the Tempest.
The Royal Air Force was looking for a quicker solution, and Camm started working on a new laminar flow wing, which would further improve the Tempest’s speed. Further refinements were done to other aerodynamic components, too, like the radiator, since the Tempest V’s liquid-cooled Napier Sabre engine was to be used. After some experiments with new arrangements, an annular radiator directly behind the propeller was chosen – certainly inspired by fast German aircraft like the Fw 190D and developed by Napier.
A total of three prototypes were ordered; the first one was powered by a Napier Sabre IIA liquid-cooled H-24 sleeve-valve engine, generating 2,180 hp (1,625 kW), but the second and any following aircraft carried the more powerful Sabre V with 2,340 hp, driving a Rotol four-blade propeller. Later aircraft were even to carry the Napier Sabre VII, which was capable of developing 3,400–4,000 hp (2,535–2,983 kW) and pushing the top speed to 485 mph (780 km/h) and more. The third airframe was just a static test structure. However, since the differences between the Tempest and the new aircraft had become almost as big as to its predecessor, the Typhoon, the new type received its own name Cyclone.
The first Cyclone Mk. I to fly, on 30 August 1944, was NV950, and it became clear soon that the modifications would improve the Cyclone’s top speed vs. the Tempest by almost 30 mph (50 km/h), but the new components would also require a longer testing period than expected. The annular radiator frequently failed and overheated, and the new, slender wings caused directional stability problems so that the complete tail section had to be re-designed. This troubling phase took more than 6 months, so that eventual service aircraft would only be ready in mid-1945 – too late for any serious impact in the conflict.
However, since the Hawker Fury, the land-based variant of the Sea Fury, which had been developed from the Tempest for the Royal Navy in parallel, had been cancelled, the Royal Air Force still ordered 150 Cyclone fighters (F Mk. I), of which one third would also carry cameras and other reconnaissance equipment (as Cyclone FR Mk.II). Due to the end of hostilities in late 1945, this order immediately lost priority. Consequently, the first production Cyclone fighters were delivered in summer 1946 – and in the meantime, jet fighters had rendered the piston-powered fighters obsolete, at least in RAF service. As a consequence, all Cyclones were handed over to friendly Commonwealth nations and their nascent air forces, e. g. India, Thailand or Burma. India received its first Cyclones in late 1947, just when the Kashmir conflict with Pakistan entered a hot phase. The machines became quickly involved in this conflict from early 1948 onwards.
Cyclones played an important role in the strikes against hostiles at Pir Badesar and the dominating Pir Kalewa. The taking of Ramgarh fort and Pt. 6944 on the west flank of Bhimbar Gali was to be a classic close support action with Indian forces carrying out a final bayonet charge against the enemy trenches whilst RIAF Cyclones and Tempests strafed and rocketed the trenches at close quarters. On a chance reconnaissance, enemy airfields were located at Gilgit and 40 NMs south, at Chilas. Cyclones flew several strikes against the landing strips in Oct and Nov 48, cratering & damaging both and destroying several hangars, barracks and radio installations. This attack destroyed Pakistani plans to build an offensive air capability in the North. Already, with Tempests and Cyclones prowling the valleys, Pakistani re-supply by Dakotas had been limited to hazardous night flying through the valleys.
After the end of hostilities in late 1948 and the ensuing independence, the Cyclone squadrons settled into their peace time stations. However, constant engine troubles (particularly the radiator) continued to claim aircraft and lives and the skill required to land the Cyclone because of its high approach speed continued to cause several write offs. The arrival of the jet-engined Vampire were the first signs of the Cyclone’s demise. As the IAF began a rapid expansion to an all jet force, several Tempest and Cyclone squadrons began converting to Vampires, 7 Squadron being the first in Dec 49. By this time it had already been decided that the piston-engine fighters would be relegated to the fighter lead-in role to train pilots for the new jet fighters. A conversion training flight was set up at Ambala in Sep 49 with Spitfire T Mk IXs, XVIIIs and Tempests to provide 16 hrs/six weeks of supervised Tempest training. This unit eventually moved to Hakimpet two years later and operated till the end of 1952. Some Cyclone FR Mk. IIs remained in front line service until 1954, though.

The kit and its assembly:
Another episode in the series “Things to make and do with Supermarine Attacker wings”. And what started as a simple switch of wings eventually turned into a major kitbashing, since the model evolved from a modded Tempest into something more complex and conclusive.
The initial spark was the idea of a Hawker alternative to Supermarine’s Spiteful and Seafang developments – especially with their slender laminar flow wings. Wouldn’t a Hawker alternative make sense?
Said and done, I dug out a NOVO Attacker kit and a Matchbox Tempest, and started measuring – and the wing transplantation appeared feasible! I made the cut on the Tempest wing just outside of the oil cooler, and the Attacker wings were then attached to these stubs – after some gaps for the landing gear wells had been cut into the massive lower wing halves. The stunt went more smoothly than expected, the only cosmetic flaw is that the guns went pretty far outboard, but that’s negligible.
But the different wings were not enough. I had recently seen in a book a picture of a Tempest (NV 768) with an experimental annular radiator for the Sabre engine (looking like a streamlined Tempest II), and wondered if this arrangement would have been the aerodynamically more efficient solution than the bulbous chin radiator of the Tempest V and VI? I decided to integrate this feature into my build, too, even though not as a copy of the real-world arrangement. The whole nose section, even though based on the OOB Mk. V nose, was scratched and re-sculpted with lots of putty. The radiator intake comes from a FROG He 219, with the front end opened and a fan from a Matchbox Fw 190 placed inside, as well as a styrene tube for the new propeller. The latter was scratched, too, from a Matchbox He 70 spinner and single blades from an Italeri F4U, plus a metal axis. The exhaust stubs were taken OOB, but their attachment slits had to be re-engraved into the new and almost massive nose section.
Once the wings and the nose became more concrete, I found that the Tempest’s original rounded tail surfaces would not match with the new, square wings. Therefore I replaced the stabilizers with donations from a Heller F-84G and modified the fin with a new, square tip (from an Intech Fw 190D) and got rid of the fin fillet – both just small modifications, but they change the Tempest’s profile thoroughly.
In order to underline the aircraft’s new, sleek lines, I left away any ordnance – but instead I added some camera fairings: one under the rear fuselage or a pair of vertical/oblique cameras, and another camera window portside for a horizontal camera. The openings were drilled, and, after painting, the kit the camera windows were created with Humbrol Clearfix.
Painting and markings:
Somehow I thought that this aircraft had to carry Indian markings – and I had a set of standard Chakra Wheels from the late Forties period in my stash. The camouflage is, typical for early IAF machines of British origin, RAF standard, with Dark Green and Ocean Grey from above and Medium Sea Grey from below. I just used the more brownish pst-war RAF Dark Green tone (Humbrol 163), coupled with the rather light Ocean Grey from Modelmaster (2057). The underside became Humbrol 165. All interior surfaces were painted with RAF Interior Green, nothing fancy. The only colorful addition is the saffron-colored spinner, in an attempt to match the fin flash’s tone.
As a standard measure, the kit received a black ink wash and some panel post-shading with lighter tones – only subtly, since the machine was not to look too weathered and beaten, just used from its Kashmir involvements.
The national markings come from a Printscale Airspeed Oxford sheet, the tactical code with alternating white and black letters, depending on the underground (the sky fuselage band comes from a Matchbox Brewster Buffalo), was puzzled together from single letters from TL Modellbau – both seen on different contemporary RIAF aircraft.
As another, small individual detail I gave the machine a tactical code letter on the fuselage, and the small tiger emblems under the cockpit were home-printed from the official IAF No. 1 Squadron badge.
Despite the massive modifications this one is a relatively subtle result, all the changes become only visible at a second glance. A sleek aircraft, and from certain angley the Cyclone looks like an A-1 Skyraider on a diet?

Some background:
The 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 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.

Some background:
The Gudkov Gu-1 was a Soviet fighter aircraft produced shortly after World War II in small numbers at the start of the jet age, but work on the Gudkov Gu-1 already started in 1944. Towards the end of World War II the Soviet Union saw the need for a strategic bombing capability similar to that of the United States Army Air Forces. The Soviet VVS air arm had the locally designed Petlyakov Pe-8 four-engined heavy bomber in service at the start of the war, but only 93 had been built by the end of the war and the type had become obsolete. By that time the U.S. regularly conducted bombing raids on Japan from distant Pacific forward bases using B-29 Superfortresses, and the Soviet Air Force lacked this capability.
Joseph Stalin ordered the development of a comparable bomber, and the U.S. twice refused to supply the Soviet Union with B-29s under Lend Lease. However, on four occasions during 1944, individual B-29s made emergency landings in Soviet territory and one crashed after the crew bailed out. In accordance with the Soviet–Japanese Neutrality Pact, the Soviets were neutral in the Pacific War and the bombers were therefore interned and kept by the Soviets. Despite Soviet neutrality, America demanded the return of the bombers, but the Soviets refused. Three repairable B-29s were flown to Moscow and delivered to the Tupolev OKB. One B-29 was dismantled, the second was used for flight tests and training, and the third one was left as a standard for cross-reference.
Stalin told Tupolev to clone the Superfortress in as short a time as possible. The reverse-engineering effort involved 900 factories and research institutes, who finished the design work during the first year. 105,000 drawings were made, and the American technology had to be adapted to local material and manufacturing standards – and ended in a thorough re-design of the B-29 “under the hood”. By the end of the second year, the Soviet industry was to produce 20 copies of the aircraft ready for State acceptance trials.
While work on what would become the Tupolev Tu-4 was on the way, the need for a long range escort fighter arose, too. Soviet officials were keen on the P-51 Mustang, but, again, the USA denied deliveries, so that an indigenous solution had to be developed. With the rising tension of international relationships, this became eventually the preferred solution, too.
While the design bureau Lavochkin had already started with work on the La-9 fighter (which entered service after WWII) and the jet age was about to begin, the task of designing a long range escort fighter for the Tu-4 was relegated to Mikhail I. Gudkov who had been designing early WWII fighters like the LaGG-1 and -3 together with Lavochkin. Internally, the new fighter received the project handle "DIS" (Dalnij Istrebitel' Soprovozhdenya ="long-range escort fighter").
In order to offer an appropriate range and performance that could engage enemy interceptors in the bombers’ target area it was soon clear that neither a pure jet nor a pure piston-engine fighter was a viable solution – a dilemma the USAAF was trying to solve towards 1945, too. The jet engine alone did not offer sufficient power, and fuel consumption was high, so that the necessary range could never be achieved with an agile fighter. Late war radials had sufficient power and offered good range, but the Soviet designers were certain that the piston engine fighter had no future – especially when fast jet fighters had to be expected over enemy territory.
Another problem arose through the fact that the Soviet Union did not have an indigenous jet engine at hand at all in late 1945. War booty from Germany in the form of Junkers Jumo 004 axial jet engines and blueprints of the more powerful HeS 011 were still under evaluation, and these powerplants alone did neither promise enough range nor power for a long range fighter aircraft. Even for short range fighters their performance was rather limited – even though fighters like the Yak-15 and the MiG-9 were designed around them.
After many layout experiments and calculation, Gudkov eventually came up with a mixed powerplant solution for the DIS project. But unlike the contemporary, relatively light I-250 (also known as MiG-13) interceptor, which added a mechanical compressor with a primitive afterburner (called VRDK) to a Klimov VK-107R inline piston engine, the DIS fighter was equipped with a powerful radial engine and carried a jet booster – similar to the US Navy’s Ryan FR-1 “Fireball”. Unlike the FR-1, though, the DIS kept a conservative tail-sitter layout and was a much bigger aircraft.
The choice for the main powerplant fell on the Shvetsov ASh-82TKF engine, driving a large four blade propeller. This was a boosted version of the same 18 cylinder twin row radial that powered the Tu-4, the ASh-73. The ASh-82TKF for the escort fighter project had a rating of 2,720 hp (2,030 kW) while the Tu-4's ASh-73TK had "only" a temporary 2,400 hp (1,800 kW) output during take-off. The airframe was designed around this massive and powerful engine, and the aircraft’s sheer size was also a result of the large fuel capacity which was necessary to meet the range target of at least 3.000 km (1.860 mi, 1.612 nmi).
The ASh-82TKF alone offered enough power for a decent performance, but in order to take on enemy jet fighters and lighter, more agile propeller-driven fighters, a single RD-20 axial-flow turbojet with 7.8 kN (1,754 lbf) thrust was added in the rear-fuselage. It was to add power for take-off and in combat situations only. Its fixed air intakes were placed on the fuselage flanks, right behind the cockpit, and the jet pipe was placed under the fin and the stabilizers.
Outwardly, Gudkov’s DIS resembled the late American P-47D or the A-1 Skyraider a lot, and the beefy aircraft was comparable in size and weight, too. But the Soviet all-metal aircraft was a completely new construction and featured relatively small and slender laminar flow wings. The wide-track landing gear retracted inwards into the inner wings while the tail wheel retracted fully into a shallow compartment under the jet pipe.
The pilot sat in a spacious cockpit under a frameless bubble canopy with very good all-round visibility and enjoyed amenities for long flights such as increased padding in the seat, armrests, and even a urinal. In addition, a full radio navigation suite was installed for the expected long range duties over long stretches of featureless landscape like the open sea.
Armament consisted of four 23 mm Nudelman-Suranov NS-23 cannons with 100 RPG in the wings, outside of the propeller arc. The guns were good for a weight of fire of 6kg (13.2 lb)/sec, a very good value. Five wet hardpoints under the fuselage, the wings outside of the landing gear well and under the wing tips could primarily carry auxiliary drop tanks or an external ordnance of up to 1.500 kg (3.300 lb).
Alternatively, iron bombs of up to 500 kg (1.100 lb) caliber could be carried on the centerline pylon, and a pair of 250 kg (550 lb) bombs under the wings, but a fighter bomber role was never seriously considered for the highly specialized and complex aircraft.
The first DIS prototype, still without the jet booster, flew in May 1947. The second prototype, with both engines installed, had its fuel capacity increased by an additional 275 l (73 US gal) in an additional fuel tank behind the cockpit. The aircraft was also fitted with larger tires to accommodate the increased all-up weight, esp. with all five 300 l drop tanks fitted for maximum range and endurance.
Flight testing continued until 1948 and the DIS concept proved to be satisfactory, even though the complicated ASh-82TKF hampered the DIS’ reliability - to the point that fitting the ASh-73TK from the Tu-4 was considered for serial production, even if this would have meant a significant reduction in performance. The RD-20 caused lots of trouble, too. Engine reliability was generally poor, and re-starting the engine in flight did not work satisfactorily – a problem that, despite several changes to the starter and ignition system, could never be fully cured. The jet engine’s placement in the tail, together with the small tail wheel, also caused problems because the pilots had to take care that the tail would not aggressively hit the ground upon landings, because the RD-20 and its attachments were easily damaged.
Nevertheless, the DIS basically fulfilled the requested performance specifications and was, despite many shortcomings, eventually cleared for production in mid 1948. It received the official designation Gudkov Gu-1, honoring the engineer behind the aircraft, even though the aircraft was produced by Lavochkin.
The first machines were delivered to VVS units in early 1949 - just in time for the Tu-4's service introduction after the Russians had toiled endlessly on solving several technical problems. In the meantime, jet fighter development had quickly progressed, even though a purely jet-powered escort fighter for the Tu-4 was still out of question. Since the Gu-1 was capricious, complex and expensive to produce, only a limited number left the factories and emphasis was put on the much simpler and more economical Lavochkin La-11 escort fighter, a lightweight evolution of the proven La-9. Both types were regarded as an interim solution until a pure jet escort fighter would be ready for service.
Operationally the Gu-1s remained closely allocated to the VVS’ bomber squadrons and became an integral part of them. Anyway, since the Tu-4 bomber never faced a serious combat situation, so did the Gu-1, which was to guard it on its missions. For instance, both types were not directly involved in the Korean War, and the Gu-1 was primarily concentrated at the NATO borders to Western Europe, since bomber attacks in this theatre would certainly need the heavy fighter’s protection.
The advent of the MiG-15 - especially the improved MiG-15bis with additional fuel capacities and drop tanks, quickly sounded the death knell for the Gu-1 and any other post-WWII piston-engine fighter in Soviet Service. As Tu-4 production ended in the Soviet Union in 1952, so did the Gu-1’s production after only about 150 aircraft. The Tu-4s and their escort fighters were withdrawn in the 1960s, being replaced by more advanced aircraft including the Tupolev Tu-16 jet bomber (starting in 1954) and the Tupolev Tu-95 turboprop bomber (starting in 1956).
The Gudkov Gu-1, receiving the NATO ASCC code “Flout”, remained a pure fighter. Even though it was not a success, some proposals for updates were made - but never carried out. These included pods with unguided S-5 air-to-air-rockets, to be carried on the wing hardpoints, bigger, non-droppable wing tip tanks for even more range or, alternatively, the addition of two pulsejet boosters on the wing tips.
There even was a highly modified mixed powerplant version on the drawing boards in 1952, the Gu-1M. Its standard radial powerplant for cruise flight was enhanced with a new, non-afterburning Mikulin AM-5 axial flow jet engine with 2.270 kgf/5,000 lbf/23 kN additional thrust in the rear fuselage. With this temporary booster, a top speed of up to 850 km/h was expected. But to no avail - the pure jet fighter promised a far better performance and effectiveness, and the Gu-1 remained the only aircraft to exclusively carry the Gudkov name.

The kit and its assembly:
This whif is the incarnation of a very effective kitbashing combo that already spawned my fictional Japanese Ki-104 fighter, and it is another submission to the 2018 “Cold War” group build at whatifmodelers.com. This purely fictional Soviet escort fighter makes use of my experiences from the first build of this kind, yet with some differences.
The kit is a bashing of various parts and pieces:
· Fuselage, wing roots, landing gear and propeller from an Academy P-47D
· Wings from an Ark Model Supermarine Attacker (ex Novo)
· Tail fin comes from a Heller F-84G
· The stabilizers were taken from an Airfix Ki-46
· Cowling from a Matchbox F6F, mounted and blended onto the P-47 front
· Jet exhaust is the intake of a Matchbox Me 262 engine pod
My choice fell onto the Academy Thunderbolt because it has engraved panel lines, offers the bubble canopy as well as good fit, detail and solid material. The belly duct had simply been sliced off, and the opening later faired over with styrene sheet and putty, so that the P-47’s deep belly would not disappear.
The F6F cowling was chosen because it looks a lot like the ASh-73TK from the Tu-4. But this came at a price: the P-47 cowling is higher, tighter and has a totally different shape. It took serious body sculpting with putty to blend the parts into each other. Inside of the engine, a styrene tube was added for a metal axis that holds the uncuffed OOB P-47 four blade propeller. The P-47’s OOB cockpit tub was retained, too, just the seat received scratched armrests for a more luxurious look.
The Attacker wings were chosen because of their "modern" laminar profile. The Novo kit itself is horrible and primitive, but acceptable for donations. 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 outside of the large main wheel wells. The intersection with the Attacker wings is almost perfect in depth and width, relatively little putty work was necessary in order to blend the parts into each other. I just had to cut out new landing gear wells from the lower halves of the Attacker wings, and with new attachment points the P-47’s complete OOB landing gear could be used.
With the new wing shape, the tail surfaces had to be changed accordingly. The trapezoid stabilizers come from an Airfix Mitsubishi Ki-46, and their shape is a good match. The P-47 fin had to go, since I wanted something bigger and a different silhouette. The fuselage below was modified with a jet exhaust, too. I actually found a leftover F-84G (Heller) tail, complete with the jet pipe and the benefit that it has plausible attachment points for the stabilizers far above the jet engine in the Gu-1’s tail.
However, the F-84 jet pipe’s diameter turned out to be too large, so I went for a smaller but practical alternative, a Junkers Jumo 004 nacelle from a Me 262 (the ancestor of the Soviet RD-20!). Its intake section was cut off, flipped upside down, the fin was glued on top of it and then the new tail was glued to the P-47 fuselage. Some (more serious) body sculpting was necessary to create a more or less harmonious transition between the parts, but it worked.
The plausible placement of the air intakes and their shape was a bit of a challenge. I wanted them to be obvious, but still keep an aerodynamic look. An initial idea had been to keep the P-47’s deep belly and widen the central oil cooler intake under the nose, but I found the idea wacky and a bit pointless, since such a long air duct would not make much sense since it would waste internal space and the long duct’s additional weight would not offer any benefit?
Another idea were air intakes in the wing roots, but these were also turned down since the landing gear wells would be in the way, and placing the ducts above or below the wings would also make no sense. A single ventral scoop (looking like a P-51 radiator bath) or two smaller, dorsal intakes (XP-81 style) behind the cockpit were other serious candidates – but these were both rejected because I wanted to keep a clean side profile.
I eventually settled for very simple, fixed side intakes, level with the jet exhaust, somewhat inspired by the Lavochkin La-200B heavy fighter prototype. The air scoops are simply parts from an Italeri Saab 39 Gripen centerline drop tank (which has a flat, oval diameter), and their shape is IMHO a perfect match.
Painting and markings:
While the model itself is a wild mix of parts with lots of improvisation involved, I wanted to keep the livery rather simple. The most plausible choice would have been an NMF finish, but I rather wanted some paint – so I used Soviet La-9 and -11 as a benchmark and settled for a simple two-tone livery: uniform light grey upper and light blue lower surfaces.
I used RAF Medium Sea Grey (Humbrol 165) and Soviet Underside Blue (Humbrol 114) as basic tones, and, after a black ink wash, these were lightened up through dry-brushed post-shading. The yellow spinner and fin tip are based on typical (subtle) squadron markings of the late 40ies era.
The cockpit as well the engine and landing gear interior became blue-grey (Revell 57), similar to the typical La-9/11’s colors. The green wheel discs and the deep blue propeller blades are not 100% in the aircraft's time frame, but I added these details in order to enhance the Soviet touch and some color accents.
Tactical markings were kept simple, too. The "38" and the Red Stars come form a Mastercraft MiG-15, the Guards badge from a Begemoth MiG-25 sheet and most of the stencils were taken from a Yak-38 sheet, also from Begemoth.
Finally, the kit was sealed with matt acrylic varnish (Italeri) and it received some mild soot stains and chipped paint around the cockpit and on the leading edges. Some oil stains were added around the engine (with Tamiya Smoke), too.
A massive aircraft, and this new use of the P-47/Attacker combo results again in a plausible solution. The added jet engine might appear a bit exotic, but the mixed powerplant concept was en vogue after WWII, but only a few aircraft made it beyond the prototype stage.
While painting the model I also wondered if an all dark blue livery and some USN markings could also have made this creation the Grumman JetCat? With the tall fin, the Gu-1 could also be an F8F Bearcat on steroids? Hmmm...

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

The kit and its assembly:
A subtle kitbashing project, inspired by a CG-rendition of a carrier-based (yet un-navalized) BAe Hawk 200 in Indian Navy service by fellow user SPINNERS in January 2021. I found the idea inspiring but thought that the basic concept could be taken further and into hardware form with a model. And I had a Matchbox Hawk 200 in The Stash™, as well as a McDonnell T-45 trainer from Italeri…
The plan sounds simple: take a T-45 and replace the cockpit section with the single-seat cockpit from the Hawk 200. And while the necessary cuts were easy to make, reality rears its ugly head when you try to mate parts from basically the same aircraft but from models by different manufacturers.
The challenges started with the fact that the fuselage shapes of both models differ – the Matchbox kit is more “voluminous”, and the different canopy shape called for a partial spine transplant, which turned out to be of very different shape than the T-45’s respective section! Lots of PSR…
In order to improve the pretty basic Matchbox Hawk cockpit I integrated the cockpit tub from the Italeri T-45, including the ejection seat, dashboard and its top cover.
For the totally different T-45 front wheel I had to enlarge the respective well and added a “ceiling” to it, since the strut had to be attached somewhere. The Hawk 200’s ventral tub for the cannons (which only the first prototype carried, later production aircraft did not feature them) were retained – partly because of their “whiffy“ nature, but also because making it disappear would have involved more major surgeries.
Most of the are behind the cockpit comes from the Italeri T-45, I just added a RHAWS fairing to the fin, extending it by 3mm.
A major problem became the air intakes, because the two kits differ in their construction. I wanted to use the Italeri parts, because they match the fairings on the fuselage flanks well and are better detailed than the Matchbox parts. But the boundary layer spacers between intakes and fuselage are molded into the Italeri parts, while the Matchbox kit has them molded into the fuselage. This called for major surgery and eventually worked out fine, and more PSR blended the rest of the fuselage donors around the cockpit together. A tedious process, though.
The pylons were puzzled together, including a former Matchbox EA-6B wing pylon under the fuselage, cut down and mounted in reverse and upside down! The ordnance comes from the Italeri NATO weapons set (Matra Magic and AGM-84), the ventral drop tank comes IIRC from an Eduard L-39 Albatros. Matra Magics were chosen because India never operated any Sidewinder AAM, just French or Soviet/Russian missiles like the R-60 or R-73 (unlikely on the Hawk, IMHO), and I had preferred a pair of Sea Eagle ASMs (from a Hasegawa Sea Harrier kit), but their span turned out to be too large for the Hawk’s low wings. The alternative, more slender Harpoons are plausible, though, since they are actually part of the Indian Navy’s inventory.
Painting and markings:
The Indian Navy theme was already settled, and I wanted to stay close to SPINNERS’ illustration as well as to real world Indian Navy aircraft. SPINNERS’ Hawk carried the typical Sea Harreir scheme in Extra Dark Sea Grey and White, and I found this livery to look a bit too much retro, because I’d place this what-if aircraft in the early 2020s, when the Sea Harriers had already been phased out. A “realistic” livery might have been an overall mid-grey paint scheme (like the land-based Indian Hawk 132s), but I found this to look too boring. As a compromise, I gave the Samudree Baaj a simple two-tone paint scheme, carried by a few late Indian Sea Harriers. It consists of upper surfaces in Dark Sea Grey (Humbrol 164) and undersides in Medium Sea Grey (Modelmaster 2058), with a low waterline. The Modelmaster MSG has – for my taste – a rather bluish hue and appears almost like PRU Blue, but I left it that way.
The decals were puzzled together from variosu sources. the roundels come from a MiG-21F (Begemot), the unit markings and tactical codes from a Model Alliance Sea Harrier sheet, and the stencils are a mix from the Matchbox Hawk 200 and the Italeri T-45.
The kit was sealed with matt acrylic varnish from Italeri.
The fictional HAL „Samudree Baaj“ looks simple, but combining kits of the basically same aircraft from different manufacturers reveals their differences, and they are not to be underestimated! However, I like the result of a navalized Hawk single-seater, and - also with the relatively simple and dull livery - it looks pretty convincing.
Many thanks to SPINNERS for the creative inspiration - even though my build is not a 100% "copy" of the artwork, but rather a step further into the navalisation idea with the T-45 parts.
