Some background:

The AMD Mystère S represents one of the many evolutionary steps in French 2nd generation jet fighter aircraft design, which began with the straight-wing Dassault Ouragan and progressed through the Mystère II/III and Mystère IV to the supersonic Super Mystère SM2B. Internally designated AMD 461 and originally called the Mystère X (Roman numeral “10”, not the letter “X”), the new aircraft was the attempt to improve the successful Mystère IV from 1953 in many respects, following Marcel Dassaults strategy to take small, evolutionary steps instead of radical quantum leaps. While the overall outlines were similar and followed the proven layout of the former Dassault jet fighters, the AMD 461 was a completely new design, though.

 

First of all, the machine was from the start designed around the indigenous axial-flow Atar 101 jet engine, since it had become obvious that the former radial-flow engines used in Dassault’s fighters, like the Rolls-Royce Tay and its French-built version, the Hispano-Suiza Verdon 350, did not offer the potential for sustained supersonic performance in level flight. As a result, the fuselage became thinner and the aircraft had a less tubby look. Furthermore, in order to achieve the ambitious performance goals, a new wing was devised, and it incorporated leading edges made from novel composite materials. The wing shape was more complex than previous AMD designs: unlike the simple trapezoid Mystère II and IV wing designs, the AMD 461’s wings had kinked wing leading edges at about half span, so that the wing root sections were extended forward and had a slightly stronger sweep than the outer wing sections (47° vs. 45°), resulting in a crescent planform with rounded tips. Dogteeth at the kinks’ position increased the wings’ critical Mach number, augmented by small boundary layer fences. A novelty were power-operated ailerons. The tail surfaces were swept, too, and featured a variable-incidence tail plane.

 

The Mystère IV’s circular nose air intake arrangement was retained, but the intake received a sharper lip for better aerodynamic efficiency at high speed. The intake ducts were split deeper down inside of the fuselage, flanking the cockpit and the weapon bay behind it (see below) on both sides. The small ranging radar, originally developed for the upgraded Mystère IVB (which never made it into series production due to a fatal prototype crash and the progress of AMD’s other supersonic projects), was relocated and now mounted on top of the intake section, reminiscent of the F-86’s arrangement. A gun camera was placed outside of the intake in a small fairing on the starboard side. Two pitots under the air intake (one main and a secondary sensor) replaced the Mystère IV’s single wing-mounted sensor boom.

 

Being a classic “gunfighter”, the AMD 461’s main armament comprised a pair of 30mm DEFA cannon in the lower front fuselage, taken over from the Mystère IV, and a retractable Type 103 pannier for 45 unguided MATRA missiles against air or ground targets behind the front wheel well. Four underwing hardpoints could carry a total payload of 1.500 kg (3.300 lb), including a pair of supersonic 625 l drop tanks on the inner pair of pylons. A typical fighter weapon were lightweight Matra Type 116M launchers, each with 19 unguided SNEB-68 air-to-air rockets. Up to four could be carried under the wings. In a secondary attack/fighter bomber role, bombs of various caliber (up to 500 kg/1.100 lb on the inner and 250 kg/550 lb on the outer hardpoints) and other unguided missiles/pods were possible, too.

 

The first Mystère X prototype was powered by the Atar 101D with 29,420 N (6,610 lbf) of thrust, and it flew successfully in June 1953. However, due to the lack of an afterburner at this stage, the machine could only become supersonic in a dive, just like the former Mystère fighters, and it offered in this guise only minimal performance improvements – even though the handling near Mach 1 was already noticeably better. The initial flight test program was successful, though, and the Armée de l’Air immediately placed an order for 100 Mystère X aircraft, intended to improve the Armée de l’Air’s interception capabilities as soon as possible. Serial production started instantaneously, even while the flight tests were still ongoing, and the production machines were powered by the newly developed Atar 101F, which had just been cleared for production and operation on the Mystère X prototype. The Atar 101F was basically a D model with an afterburner added to it, to produce a temporary thrust of 37,300 N (8,400 lbf) and ensure the desired top speed in level flight of more than Mach 1. As a result, the Mystère X’s tail section had to be modified to accommodate the new engine’s longer tailpipe, which did not feature an adjustable nozzle yet – it was simply extended beyond the fin’s trailing edge, and even then the longer jet pipe protruded from the hull. However, this modification was successful and incorporated into the serial aircraft. With the Atar 101F, the serial production Mystère X’s performance was appreciably improved: beyond supersonic top speed, initial rate of climb was almost doubled in comparison with the Mystère IV, but the thirsty afterburner engine almost nullified any gain in range from the new type’s higher internal fuel capacity. Drop tanks had to be carried almost all the time.

 

The quick (if not hastened) order for the Mystère X also served as an insurance policy in the event of the AMD effort failing to produce an even more capable supersonic aircraft with the Mystère XX, a project that had been under development as a private venture in parallel, but with a time lag of about two years and benefitting from the research that had been done for the AMD 461. However, both designs turned out to be successful and both were adopted for service. They became known to the public as the Mystère S (for ‘supersonique’) and the Super Mystère, respectively. The first Super Mystère prototype, powered by a Rolls-Royce Avon RA.7R, took to the air on 2 March 1955, and the promising aircraft already broke the sound barrier in level flight the following day. The Super Mystère turned out to be the more capable and modern aircraft thanks to its new, more powerful Atar 109G-2 engine.

 

The more capable Super Mystère was immediately favored and, as a consequence, the running Mystère S order was cancelled in May 1955 and its initial production run limited to a mere 54 airframes - the number that had been completed until that point. The Super Mystère became the Armée de l’Air’s standard fighter for the late Fifties and production was quickly switched to the new type, 180 specimen were eventually built. Since a mix of types in the operational fighter squadrons was not economical, the Armée de l’Air decided to separate them and find a different role for the young but relatively small Mystère S fleet. Since the aircraft had a rugged airframe and had shown very good handling characteristics at medium to low altitude, and because the Armée de l’Air was lacking a fast, tactical and indigenous reconnaissance aircraft at that time (the standard type was the RF-84F), the Armée de l’Air decided in 1956 to convert the Mystère S fighters accordingly.

 

This modification was a relatively easy task: The retractable missile pannier (which was hardly ever used) was removed and its well behind the cockpit offered sufficient internal space for optical reconnaissance equipment in a conditioned compartment. This comprised four OMERA cameras (less than the RF-84F’s six cameras), covered by a ventral canoe fairing. One camera was facing forward, two were set on mounts that allowed vertical photography or camera orientation to either port or starboard, and the fourth camera had a panoramic field of view. After these modifications, the machines were re-designated Mystère SR to reflect their new role and capabilities.

 

Initially, the converted machines retained the twin DEFA cannon armament and full external stores capability. Typical load in the new photo-recce role was the standard pair of drop tanks, plus optional flares for night photography. In this guise the Mystère SR fleet was distributed among two reconnaissance units, ER 2/33 “Savoie” and ER 3/33 “Moselle” in Eastern France, close to the German border, starting service in April 1957.

Later in their career, the Mystère SR’s guns and also the ranging radar equipment (even though the empty small radome was retained) were often removed. This was initially a weight-saving measure for better performance, but due to their short legs many Mystère SRs had extra fuel tanks added to the former gun and ammunition bays. In some cases the space was used to house additional mission equipment, the aircrafts’ designation did not change, though. The integration of the new Matra R.550 Magic AAM was considered briefly in 1970, but not deemed relevant for the Mystère SR’s mission profile. However, eight late-production Mystère SRs received a new, bigger panoramic OMERA camera, which necessitated a larger ventral fairing and some other internal changes. These machines were re-designated Mystère SRP (‘panoramique’). Another early Mystère SR was used for the development of indigenous infra-red linescan and side looking airborne radar systems, which were both later incorporated in an under-fuselage pod for the Mirage IIIR.

 

Having become quickly obsolete through the introduction of 3rd generation jet fighters in the early Sixties – namely the Mirage III – the Mystère SR’s active career only lasted a mere 10 years, and the Mirage III’s fighter variants quickly replaced the Super Mystère, too. Due to its many limitations, the Mystère SR was soon replaced by the Mirage IIIR reconnaissance version, by 1974 all aircraft had been retired. Another reason for this early operational end were durability problems with the composite elements on the aircraft’s wings – there had been no long-term experience with the new material, but the elements tended to become brittle and collapse under stress or upon bird strikes. AMD conceived a plan to replace the affected panels with light metal sheets, but this update, which would have prolonged service life for 10 more years, was not carried out. After spending 5 years in mothballed storage, all surviving Mystère SR airframes were scrapped between 1980 and 1981.

The kit and its assembly:

A project I had on my idea list for a long time – there were so many AMD jet fighter designs (both that entered service but also many paper projects and prototypes) during the Fifties and Sixties that I wondered if I could smuggle a what-if type somewhere into the lineage. A potential basis appeared when I recognized that the British Supermarine Swift had a fuselage shape quite similar to the contemporary French fighters, and from this impression the idea was born to “Frenchize” a Swift.

 

This called for a kitbash, and I used a Matchbox Mystère IV (Revell re-boxing) for the French donor elements that would be grafted onto an Xtrakit FR.5 model, which looks good in the box but has serious fit issues, e.g. between the rear fuselage halves or when the wings have to be mated with the completed fuselage.

The transplantations from the rather primitive/blunt Matchbox Mystère included the whole cockpit section except for the interior, which was taken from the in this respect much better Swift, the glazing, the spine and the whole tail with fin and stabilizers. The Swift provided most of the fuselage, the wings and the landing gear, even though I used the Mystère’s main wheels because of their characteristic hub caps/brake arrangement.

Mating the fuselage sections from the two models became a major stunt, though, because the diameters and shapes were rather different. Three-dimensional gaps and steps behihd the cockpit had to be bridged, initially with 2C putty for the rough overall shape and then with NC putty for a smooth finish. A gap in the spine in front of the fin had to be improvised/filled, too, and the Mystère’s fin had to be tailored to the different Swift rear fuselage shape, too.

The result looks a little odd, though, the Swift’s original air intake ducts now look from certain angles like hamster cheeks – but after all, the ducts have to pass the central cockpit section on both sides somehow, so that the arrangement makes nonetheless sense. And the small dorsal spine taken over from the Mystère changes the Swift’s profile considerably, as well as the shorter Dassault-style canopy.

 

The small ranging radar radome is just a piece of sprue from the Mystère kit, blended into the rest of the fuselage with putty. The interior of the air intake was heavily modified – the original splitter, positioned directly inside of the intake, was deleted and the walls trimmed down for a much thinner/sharper lip. Inside of the intake a bulkhead was added as a sight blocker, and a new splitter was mounted to the new bulkhead in a much deeper position. The gun camera fairing is a piece of styrene profile, the new twin pitots (reminiscent of the SM2B’s arrangement) were made from heated sprue material.

The camera fairing is the lower half from a P-47 drop tank, left over from a Hobby Boss kit, IIRC, and in order to fit the Swift’s cockpit tub into the Mystère’s fuselage the rear bulkhead had to be re-created with the help of paper tissue drenched with white glue.

The drop tanks come from a KP MiG-19, which had the benefit of integral, thin pylons at a suitable position for the Mystère SR. For a different look I just canted their fins downwards.

  

Painting and markings:

For a subtle impression I settled for an authentic livery: the French rendition of the USAF SEA scheme for the F-100 with local CELOMER tones, which was not only applied to the Armée de l’Air’s F-100s (these were originally delivered in NMF and camouflaged later in the Sixties), but also to the Super Mystères - the SM2Bs actually carried a quite faithful adaptation of the USAF’s F-100 pattern! However, the indigenous CELOMER paints differed from the original U.S. Federal Standard tones (FS 30219, 34102, 34079 and 36622, respectively), esp. the reddish light tan was more of an earth tone, and the dark green had a more bluish hue.

 

This offered some freedom – even more so because real life pictures of French reference aircraft show a wide range of shades of these basic tones and frequent serious weathering. Instead of the U.S. tan I went for RAF Dark Earth (Humbrol 29), the dark Forest Green was replaced with Humbrol 75 (Bronze Green). The light green became a 2:1 mix of Humbrol 117 (the original FS 34102) with Humbrol 78 (RAF Cockpit Green), for more contrast and less yellow in the tone. The undersides were painted with Humbrol 166 (RAF Light Aircraft Grey).

After a black ink wash I gave the model a thorough panel post-shading and recreated some lost panel lines with the help of silver paint, too. I also added some paint patches and touch-ups, for a rather worn look of the aircraft.

The black areas around the gun muzzles were created with the help of decal material, generic black decal sheet material was also used to create the camera windows. Grey (Revell 75) dielectric panels were added to the fin tip and behind the cockpit. The cockpit interior became very dark grey (Revell 09, Anthracite, with some dry-painted medium grey on top), while the landing gear and the respective wells were left in aluminum (Humbrol 56).

 

The decals are a mix from various sources. The ER 2/33 markings came from a Heller Mirage III sheet, which offers an optional IIIR from 1984. I also settled for relatively small roundels (from a Mirage F.1C) – a trend which started in the Armée de l’Air in the early Seventies and also comprised the deletion of the fin flash. Contemporary real world SM2Bs with the French SEA cammo frequently carried a similar type of subdued markings instead of earlier, bigger roundels found on the machines in NMF finish or on the aircraft from EC 1/12 "Cambresis" with their unique and different camouflage in two shades of green and a rather sandy tan, almost like a desert paint scheme. The white tactical code “33-PS” was improvised with single 4mm letters from TL Modellbau. The stencils were puzzled together from various Mirage III/V/F.1C sheets and also from an IAI Kfir.

 

The kit received some additional dry-painting with silver to simulate more wear, and was finally sealed with a coat of matt acrylic varnish.

  

Another “missing link” build, but I think that my Mystère S fits stylistically well into the (non-existent, though) gap between the Mystère IV and the Super Mystère, sporting vintage details like the round air intake but coupled with highly swept wings and the Swift’s elegant lines. The “traditional” French paint scheme adds to the realism - and, when put in the right background/landscape context, turns out to be very effective. Not a spectacular model, despite serious body work around the cockpit, but a convincing result.

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:

The Indian „Samudree Baaj“ (समुद्री बाज, Sea Hawk) was a highly modified, navalized version of the British BAE Systems Hawk land-based training jet aircraft, which had been manufactured under license by Hindustan Aeronautics Limited (HAL). The first indigenously built Hawk Mk. 132 trainer was delivered in 2008 to the Indian Air Force, and the type has since then been updated with indigenous avionics into the “Hawk-I” Mk. 132 from 2020 onwards. The aircraft’s Rolls Royce Adour Mk 871 engine was also license-built by HAL, and the company had experience from a wide range of aircraft projects in the past.

 

The Samudree Baaj project was initiated in 2006 by the Indian Navy, as part of the long historic plan to provide the Indian Navy with a fully capable aircraft carrier. This plan had been initiated in 1989, when India announced a plan to replace its ageing British-built aircraft carriers, INS Vikrant and INS Viraat (ex-HMS Hermes), with two new 28,000-ton Air Defence Ships (ADS) that would operate the BAe Sea Harrier aircraft. The first vessel was to replace Vikrant, which was set to decommission in early 1997. Construction of the ADS was to start at the Cochin Shipyard (CSL) in 1993 after the Indian Naval Design Organisation had translated this design study into a production model. Following the 1991 economic crisis, the plans for construction of the vessels were put on hold indefinitely.

 

In 1999, then-Defence Minister George Fernandes revived the project and sanctioned the construction of the Project “71 ADS”. By that time, given the ageing Sea Harrier fleet, the letter of intent called for a carrier that would carry more modern jet fighters. In 2001, CSL released a graphic illustration showing a 32,000-ton STOBAR (Short Take-Off But Arrested Recovery) design with a pronounced ski jump. The aircraft carrier project finally received formal government approval in January 2003. By then, design updates called for a 37,500-ton carrier to operate the MiG-29K. India opted for a three-carrier fleet consisting of one carrier battle group stationed on each seaboard, and a third carrier held in reserve, in order to continuously protect both its flanks, to protect economic interests and mercantile traffic, and to provide humanitarian platforms in times of disasters, since a carrier can provide a self-generating supply of fresh water, medical assistance or engineering expertise to populations in need for assistance.

 

In August 2006, then-Chief of the Naval Staff, Admiral Arun Prakash stated that the designation for the vessel had been changed from Air Defence Ship (ADS) to Indigenous Aircraft Carrier (IAC). The euphemistic ADS had been adopted in planning stages to ward off concerns about a naval build-up. Final revisions to the design increased the displacement of the carrier from 37,500 tons to over 40,000 tons. The length of the ship also increased from 252 metres (827 ft) to 262 metres (860 ft).

It was at this time that, beyond the MiG-29K, primarily a carrier-capable trainer and also a light (and less costly) strike aircraft would be needed. With the running production of the Hawk Mk. 132 for the Indian Air Force and BAE Systems’ connection and experience to the USA and McDonnell/Boeing’s adaptation of the Hawk as the US Navy’s carrier-capable T-45 trainer, HAL was instructed to develop a suitable aircraft family on the Hawk’s basis for the new carriers.

 

HAL’s Samudree Baaj is a fully carrier-capable version of the British Aerospace Hawk Mk. The Hawk had not originally been designed to perform carrier operations, so that numerous modifications were required, such as the extensive strengthening of the airframe to withstand the excessive forces imposed by the stresses involved in catapult launches and high sink-rate landings, both scenarios being routine in aircraft carrier operations.

 

The aerodynamic changes of the aircraft, which were mutually developed by HAL and BAE Systems, included improvements to the low-speed handling characteristics and a reduction in the approach speed. Most notable amongst the changes made to the Hawk's design were extended flaps for better low-speed handling, along with the addition of spoilers on the wings to reduce lift and strakes on the fuselage which improved airflow and stabilizer efficiency.

Other, less obvious modifications included a reinforced airframe, the adoption of a more robust and widened landing gear, complete with a catapult tow bar attachment to the oleo strut of the new two-wheel nose gear design, and an arresting hook. The tail fin was extended by 1 foot (12 in, 30.5 cm) to compensate for the loss of the Hawk’s ventral stabilizing strakes. To make room for the arrester hook, the original ventral air brake was split and re-located to the flanks, similar to the USN’s T-45 trainer.

 

At the time of the Samudree Baaj’s design, the exact catapult arrangement and capacity on board of India’s new carriers was not clear yet – even more so, since the MiG-29K and its powerful engines might have made a catapult obsolete. Therefore, the Samudree Baaj was designed to be operable either with a ski jump ramp (in the style of the Russian Kiev class carriers, of which India had purchased one as INS Vikramaditya) or with only minimal launch support within the projected STOBAR concept, which included a relatively short-stroke steam catapult and a similarly short, undampened arrester gear.

 

By 2009 the basic airframe had been defined and four prototypes were built for two versions: the Mk. 101 trainer, which was basically a navalized version of the land-based Mk. 132 with almost the same mission equipment, and the Mk. 201, a single-seater. Two airframes of each type were built and the first Samudree Baaj flight took place in early 2011. The Indian government ordered 30 trainers and 15 attack aircraft, to be delivered with the first new Indian carrier, INS Vikrant, in late 2017.

 

The Samudree Baaj Mk. 201 was developed from the basic navalized Hawk airframe as a light multirole fighter with a small visual signature and high maneuverability, but high combat efficiency and capable of both strike and point defense missions. It differed from the trainer through a completely new forward fuselage whereby the forward cockpit area, which normally housed the trainee, was replaced by an electronics bay for avionics and onboard systems, including a fire control computer, a LINS 300 ring laser gyroscope inertial navigation system and a lightweight (145 kg) multimode, coherent, pulse-Doppler I band airborne radar. This multimode radar was developed from the Ferranti Blue Fox radar and capable of airborne interception and air-to-surface strike roles over water and land, with look-down/shoot-down and look-up modes. It had ten air-to-surface and ten air-to-ground modes for navigation and weapon aiming purposes.

A ventral fairing behind the radome carried a laser rangefinder and a forward-looking infrared (FLIR). Mid-air refueling was also possible, through a detachable (but fixed) probe. GPS navigation or modern night-flight systems were integrated, too.

 

Like the trainer, the Mk. 201 had a total of seven weapon hardpoints (1 ventral, four underwing and a pair of wing tip launch rails), but the more sophisticated avionics suite allowed a wider range of ordnance to be carried and deployed, which included radar-guided AAMs for BVR strokes and smart weapons and guided missiles – especially the Sea Eagle and AGM-84 “Harpoon” anti-ship missiles in the Indian Navy’s arsenal. For the maritime strike role and as a support for ASW missions, the Samudree Baaj Mk. 201 could even deploy Sting Ray homing torpedoes.

Furthermore, a pair of 30mm (1.18 in) ADEN machine cannon with 150 RPG were housed in a shallow fairing under the cockpit. The self-protection systems include a BAE SkyGuardian 200 RWR and automatic Vinten chaff/flare dispensers located above the engine exhaust.

 

The Samudree Baaj project was highly ambitious, so that it does not wonder that there were many delays and teething troubles. Beyond the complex avionics integration this included the maritime adaptation of the Adour engine, which eventually led to the uprated Adour Mk. 871-1N, which, as a side benefit, also offered about 10% more power.

However, in parallel, INS Vikrant also ran into delays: In July 2012, The Times of India reported that construction of Vikrant has been delayed by three years, and the ship would be ready for commissioning by 2018. Later, in November 2012, Indian English-language news channel NDTV reported that cost of the aircraft carrier had increased, and the delivery has been delayed by at least five years and is expected to be with the Indian Navy only after 2018 as against the scheduled date of delivery of 2014. Work then commenced for the next stage of construction, which included the installation of the integrated propulsion system, the superstructure, the upper decks, the cabling, sensors and weapons. Vikrant was eventually undocked on 10 June 2015 after the completion of structural work. Cabling, piping, heat and ventilation works were to be completed by 2017; sea trials would begin thereafter. In December 2019, it was reported that the engines on board the ship were switched on and in November 2020, only the basin trials of the aircraft carrier were completed.

 

By that time, the first Samudree Baaj aircraft had been delivered to Indian Navy 300 squadron, and even though only based at land at Hansa Air Station, flight training and military operations commenced. In the meantime, the start of Vikrant's trials had initially been scheduled to begin on 12 March 2020, but further construction delays caused that to be moved back to April. With the COVID-19 crisis, the navy explained that trials were unlikely to begin before September/October. During the Navy Day press meeting in December 2019, Navy Chief Admiral Karambir Singh said Vikrant would be fully operational before the end of 2022. The COVID-19 pandemic had already pushed that back to 2023 and further delays appeared possible.

In late 2020, the Indian Navy expected to commission Vikrant by the end of 2021. Until then, the Samudree Baaj fleet will remain land-based at INS Hansa near Goa. This not only is the INAS 300 home base, it is also the location of the Indian Navy's Shore Based Test Facility (SBTF), which is a mock-up of the 283-metre (928 ft) INS Vikramaditya (a modified Kiev-class aircraft carrier) deck built to train and certify navy pilots, primarily the the Mikoyan MiG-29K for operating from the aircraft carrier, but now also for the Samudree Baaj and for the developmental trials of the naval HAL Tejas lightweight fighter.

The kit and its assembly:

A subtle kitbashing project, inspired by a CG-rendition of a carrier-based (yet un-navalized) BAe Hawk 200 in Indian Navy service by fellow user SPINNERS in January 2021. I found the idea inspiring but thought that the basic concept could be taken further and into hardware form with a model. And I had a Matchbox Hawk 200 in The Stash™, as well as a McDonnell T-45 trainer from Italeri…

 

The plan sounds simple: take a T-45 and replace the cockpit section with the single-seat cockpit from the Hawk 200. And while the necessary cuts were easy to make, reality rears its ugly head when you try to mate parts from basically the same aircraft but from models by different manufacturers.

 

The challenges started with the fact that the fuselage shapes of both models differ – the Matchbox kit is more “voluminous”, and the different canopy shape called for a partial spine transplant, which turned out to be of very different shape than the T-45’s respective section! Lots of PSR…

In order to improve the pretty basic Matchbox Hawk cockpit I integrated the cockpit tub from the Italeri T-45, including the ejection seat, dashboard and its top cover.

For the totally different T-45 front wheel I had to enlarge the respective well and added a “ceiling” to it, since the strut had to be attached somewhere. The Hawk 200’s ventral tub for the cannons (which only the first prototype carried, later production aircraft did not feature them) were retained – partly because of their “whiffy“ nature, but also because making it disappear would have involved more major surgeries.

Most of the are behind the cockpit comes from the Italeri T-45, I just added a RHAWS fairing to the fin, extending it by 3mm.

 

A major problem became the air intakes, because the two kits differ in their construction. I wanted to use the Italeri parts, because they match the fairings on the fuselage flanks well and are better detailed than the Matchbox parts. But the boundary layer spacers between intakes and fuselage are molded into the Italeri parts, while the Matchbox kit has them molded into the fuselage. This called for major surgery and eventually worked out fine, and more PSR blended the rest of the fuselage donors around the cockpit together. A tedious process, though.

 

The pylons were puzzled together, including a former Matchbox EA-6B wing pylon under the fuselage, cut down and mounted in reverse and upside down! The ordnance comes from the Italeri NATO weapons set (Matra Magic and AGM-84), the ventral drop tank comes IIRC from an Eduard L-39 Albatros. Matra Magics were chosen because India never operated any Sidewinder AAM, just French or Soviet/Russian missiles like the R-60 or R-73 (unlikely on the Hawk, IMHO), and I had preferred a pair of Sea Eagle ASMs (from a Hasegawa Sea Harrier kit), but their span turned out to be too large for the Hawk’s low wings. The alternative, more slender Harpoons are plausible, though, since they are actually part of the Indian Navy’s inventory.

  

Painting and markings:

The Indian Navy theme was already settled, and I wanted to stay close to SPINNERS’ illustration as well as to real world Indian Navy aircraft. SPINNERS’ Hawk carried the typical Sea Harreir scheme in Extra Dark Sea Grey and White, and I found this livery to look a bit too much retro, because I’d place this what-if aircraft in the early 2020s, when the Sea Harriers had already been phased out. A “realistic” livery might have been an overall mid-grey paint scheme (like the land-based Indian Hawk 132s), but I found this to look too boring. As a compromise, I gave the Samudree Baaj a simple two-tone paint scheme, carried by a few late Indian Sea Harriers. It consists of upper surfaces in Dark Sea Grey (Humbrol 164) and undersides in Medium Sea Grey (Modelmaster 2058), with a low waterline. The Modelmaster MSG has – for my taste – a rather bluish hue and appears almost like PRU Blue, but I left it that way.

 

The decals were puzzled together from variosu sources. the roundels come from a MiG-21F (Begemot), the unit markings and tactical codes from a Model Alliance Sea Harrier sheet, and the stencils are a mix from the Matchbox Hawk 200 and the Italeri T-45.

 

The kit was sealed with matt acrylic varnish from Italeri.

 

The fictional HAL „Samudree Baaj“ looks simple, but combining kits of the basically same aircraft from different manufacturers reveals their differences, and they are not to be underestimated! However, I like the result of a navalized Hawk single-seater, and - also with the relatively simple and dull livery - it looks pretty convincing.

Many thanks to SPINNERS for the creative inspiration - even though my build is not a 100% "copy" of the artwork, but rather a step further into the navalisation idea with the T-45 parts.

Some Background:

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.

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

  

Some background:

The TIE/LN starfighter, or TIE/line starfighter, simply known as the TIE Fighter or T/F, was the standard Imperial starfighter seen in massive numbers throughout most of the Galactic Civil War and onward.

The TIE Fighter was manufactured by Sienar Fleet Systems and led to several upgraded TIE models such as TIE/sa bomber, TIE/IN interceptor, TIE/D Defender, TIE/D automated starfighter, and many more.

 

The original TIEs were designed to attack in large numbers, overwhelming the enemy craft. The Imperials used so many that they came to be considered symbols of the Empire and its might. They were also very cheap to produce, reflecting the Imperial philosophy of quantity over quality.

 

However, a disadvantage of the fighter was its lack of deflector shields. In combat, pilots had to rely on the TIE/LN's maneuverability to avoid damage. The cockpit did incorporate crash webbing, a repulsorlift antigravity field, and a high-g shock seat to help protect the pilot, however these did next to nothing to help protect against enemy blaster fire.

 

Due to the lack of life-support systems, each TIE pilot had a fully sealed flight suit superior to their Rebel counterparts. The absence of a hyperdrive also rendered the light fighter totally dependent on carrier ships when deployed in enemy systems. TIE/LNs also lacked landing gear, another mass-reducing measure. While the ships were structurally capable of "sitting" on their wings, they were not designed to land or disembark their pilots without special support. On Imperial ships, TIEs were launched from racks in the hangar bays.

 

The high success rate of more advanced Rebel starfighters against standard Imperial TIE Fighters resulted in a mounting cost of replacing destroyed fighters and their pilots. That, combined with the realization that the inclusion of a hyperdrive would allow the fleet to be more flexible, caused the Imperial Navy to rethink its doctrine of using swarms of cheap craft instead of fewer high-quality ones, leading to the introduction of the TIE Advanced x1 and its successor, the TIE Avenger. The following TIE/D Defender as well as the heavy TIE Escort Fighter (or TIE/E) were touted as the next "logical advance" of the TIE Series—representing a shift in starfighter design from previous, expendable TIE models towards fast, well armed and protected designs, capable of hyperspace travel and long-term crew teams which gained experience and capabilities over time.

 

The TIE/E Escort, was a high-performance TIE Series starfighter developed for the Imperial Navy by Sienar Fleet Systems and it was introduced into service shortly before the Battle of Endor. It was a much heavier counterpart to the agile and TIE/D fighter, and more of an attack ship or even a light bomber than a true dogfighter. Its role were independent long range operations, and in order to reduce the work load and boost morale a crew of two was introduced (a pilot and a dedicated weapon systems officer/WSO). The primary duty profile included attack and escort task, but also reconnoiter missions. The TIE/E shared the general layout with the contemporary TIE/D fighter, but the cockpit section as well as the central power unit were much bigger, and the ship was considerably heavier.

 

The crew enjoyed – compared with previous TIE fighter designs – a spacious and now fully pressurized cockpit, so that no pressurized suits had to be worn anymore. The crew members sat in tandem under a large, clear canopy. The pilot in front had a very good field of view, while the WSO sat behind him, in a higher, staggered position with only a limited field of view. Both work stations had separate entries, though, and places could not be switched in flight: the pilot mounted the cockpit through a hatch on port side, while the WSO entered the rear compartment through a roof hatch.

 

In a departure from the design of previous TIE models, instead of two parallel wings to either side of the pilot module, the TIE Escort had three quadanium steel solar array wings mounted symmetrically around an aft section, which contained an I-s4d solar ionization reactor to store and convert solar energy collected from the wing panels. The inclusion of a third wing provided additional solar power to increase the ship's range and the ship's energy management system was designed to allow weapons and shields to be charged with minimum loss of power to the propulsion system.

 

Although it was based on the standard twin ion engine design, the TIE/E’s propulsion system was upgraded to the entirely new, powerful P-sz9.8 triple ion engine. This allowed the TIE/E a maximum acceleration of 4,220 G or 21 MGLT/s and a top speed of 144 MGLT, or 1,680 km/h in an atmosphere — almost 40 percent faster than a former standard TIE Fighter. With tractor beam recharge power (see below) redirected to the engines, the top speed could be increased to 180 MGLT in a dash.

In addition to the main thrusters located in the aft section, the TIE Escort's triple wing design allowed for three arrays of maneuvering jets and it featured an advanced F-s5x flight avionics system to process the pilot's instructions. Production models received a class 2, ND9 hyperdrive motivator, modified from the version developed for the TIE Avenger. The TIE/E also carried a Sienar N-s6 Navcon navigation computer with a ten-jump memory.

 

Special equipment included a small tractor beam projector, originally developed for the TIE Avenger, which could be easily fitted to the voluminous TIE Escort. Models produced by Ysanne Isard's production facility regularly carried such tractor beams and the technology found other uses, such as towing other damaged starfighters until they could achieve the required velocity to enter hyperspace. The tractor beam had limited range and could only be used for a short time before stopping to recharge, but it added new tactics, too. For instance, the beam allowed the TIE/E crews to temporarily inhibit the mobility of enemy fighters, making it easier to target them with the ship's other weapon systems, or prevent enemies from clear shots.

 

The TIE Escort’s weapons systems were primarily designed to engage bigger ships and armored or shielded targets, like armed freighters frequently used by the Alliance. Thanks to its complex weapon and sensor suite, it could also engage multiple enemy fighters at once. The sensors also allowed an effective attack of ground targets, so that atmospheric bombing was a potential mission for the TIE/E, too.

.

The TIE Escort Fighter carried a formidable array of weaponry in two modular weapon bays that were mounted alongside the lower cabin. In standard configuration, the TIE/E had two L-s9.3 laser cannons and two NK-3 ion cannons. The laser and ion cannons could be set to fire separately or, if concentrated power was required, to fire-linked in either pairs or as a quartet.

The ship also featured two M-g-2 general-purpose warhead launchers, each of which could be equipped with a standard load of three proton torpedoes or four concussion missiles. Depending on the mission profile, the ship could be fitted with alternative warheads such as proton rockets, proton bombs, or magnetic pulse warheads.

Additionally, external stores could be carried under the fuselage, which included a conformal sensor pallet for reconnaissance missions or a cargo bay with a capacity for 500 kg (1.100 lb).

 

The ship's defenses were provided by a pair of forward and rear projecting Novaldex deflector shield generators—another advantage over former standard TIE models. The shields were designed to recharge more rapidly than in previous Imperial fighters and were nearly as powerful as those found on capital ships, so that the TIE/E could engage other ships head-on with a very high survivability. The fighters were not equipped with particle shields, though, relying on the reinforced titanium hull to absorb impacts from matter. Its hull and wings were among the strongest of any TIE series Starfighter yet.

 

The advanced starfighter attracted the attention of several other factions, and the Empire struggled to prevent the spread of the technology. The ship's high cost, together with political factors, kept it from achieving widespread use in the Empire, though, and units were assigned only to the most elite crews.

 

The TIE/E played a central role in the Empire's campaign against rogue Grand Admiral Demetrius Zaarin, and mixed Defender and Escort units participated in several other battles, including the Battle of Endor. The TIE Escort continued to see limited use by the Imperial Remnant up to at least 44 ABY, and was involved in numerous conflicts, including the Yuuzhan Vong War..

  

The kit and its assembly:

Another group build contribution, this time to the Science Fiction GB at whatifmodelers.com during summer 2017. Originally, this one started as an attempt to build a vintage MPC TIE Interceptor kit which I had bought and half-heartedly started to build probably 20 years ago. But I did not have the right mojo (probably, The Force was not strong enough…?), so the kit ended up in a dark corner and some parts were donated to other projects.

 

The sun collectors were still intact, though, and in the meantime I had the idea of reviving the kit’s remains, and convert it into (what I thought was) a fictional TIE Fighter variant with three solar panels. For this plan I got myself another TIE Interceptor kit, and stashed it away, too. Mojo was still missing, though.

 

Well, then came the SF GB and I took it as an occasion to finally tackle the build. But when I prepared for the build I found out that my intended design (over the years) more or less actually existed in the Star Wars universe: the TIE/D Defender! I could have built it with the parts and hand and some improvisation, but the design similarity bugged me. Well, instead of a poor copy of something that was more or less clearly defined, I rather decided to create something more individual, yet plausible, from the parts at hand.

 

The model was to stay a TIE design, though, in order to use as much donor material from the MPC kits as possible. Doing some legwork, I settled for a heavy fighter – bigger than the TIE Interceptor and the TIE/D fighter, a two-seater.

Working out the basic concept and layout took some time and evolved gradually. The creative spark for the TIE/E eventually came through a Revell “Obi Wan’s Jedi Starfighter” snap fit kit in my pile – actually a prize from a former GB participation at phoxim.de (Thanks a lot, Wolfgang!), and rather a toy than a true model kit.

 

The Jedi Fighter was in so far handy as it carries some TIE Fighter design traits, like the pilot capsule and the characteristic spider web windscreen. Anyway, it’s 1:32, much bigger than the TIE Interceptor’s roundabout 1:50 scale – but knowing that I’d never build the Jedi Starfighter OOB I used it as a donor bank, and from this starting point things started to evolve gradually.

 

Work started with the cockpit section, taken from the Jedi Starfighter kit. The two TIE Interceptor cockpit tubs were then mounted inside, staggered, and the gaps to the walls filled with putty. A pretty messy task, and once the shapes had been carved out some triangular tiles were added to the surfaces – a detail I found depicted in SW screenshots and some TIE Fighter models.

 

Another issue became the crew – even though I had two MPC TIE Interceptors and, theorectically, two pilot figures, only one of them could be found and the second crewman had to be improvised. I normally do not build 1:48 scale things, but I was lucky (and happy) to find an SF driver figure, left over from a small Dougram hoovercraft kit (from Takara, as a Revell “Robotech” reboxing). This driver is a tad bigger than the 1:50 TIE pilot, but I went with it because I did not want to invest money and time in alternatives. In order to justify the size difference I decided to paint the Dougram driver as a Chiss, based on the expanded SW universe (with blue skin and hair, and glowing red eyes). Not certain if this makes sense during the Battle of Endor timeframe, but it adds some color to the project – and the cockpit would not be visible in much detail since it would be finished fully closed.

 

Reason behind the closed canopy is basically the poor fit of the clear part. OOB, this is intended as an action toy – but also the canopy’s considerable size in 1:50 would prevent its original opening mechanism.

Additional braces on the rel. large window panels were created with self-adhesive tape and later painted over.

 

The rear fuselage section and the solar panel pylons were scratched. The reactor behind the cockpit section is actually a plastic adapter for water hoses, found in a local DIY market. It was slightly modified, attached to the cockpit “egg” and both parts blended with putty. The tail opening was closed with a hatch from the OOB TIE Interceptor – an incidental but perfect match in size and style.

 

The three pylons are also lucky finds: actually, these are SF wargaming/tabletop props and would normally be low walls or barriers, made from resin. For my build, they were more or less halved and trimmed. Tilted by 90°, they are attached to the hull with iron wire stabilizers, and later blended to the hull with putty, too.

 

Once the cockpit was done, things moved more swiftly. The surface of the hull was decorated with many small bits and pieces, including thin styrene sheet and profiles, steel and iron wire in various strengths, and there are even 1:72 tank tracks hidden somewhere, as well as protective caps from syringes (main guns and under the rear fuselage). It’s amazing how much stuff you can add to such a model – but IMHO it’s vital in order to create some structure and to emulate the (early) Star Wars look.

  

Painting and markings:

The less spectacular part of the project, even though still a lot of work because of the sheer size of the model’s surface. Since the whole thing is fictional, I tried to stay true to the Imperial designs from Episode IV-VI and gave the TIE/E a simple, all-light grey livery. All basic painting was done with rattle cans.

Work started with a basic coat of grey primer. On top of that, an initial coat of RAL 7036 Platingrau was added, esp. to the lower surfaces and recesses, for a rough shading effect. Then, the actual overall tone, RAL 7047, called “Telegrau 4”, one of Deutsche Telekom’s corporate tones, was added - mostly sprayed from abone and the sides onto the model. Fuselage and panels were painted separately, overall assembly was one of the final steps.

 

The solar panels were to stand out from the grey rest of the model, and I painted them with Revell Acrylic “Iron Metallic” (91) first, and later applied a rather rich wash with black ink , making sure the color settled well into the many small cells. The effect is pretty good, and the contrast was slightly enhanced through a dry-brushing treatment.

 

Only a few legible stencils were added all around the hull (most from the scrap box or from mecha sheets), the Galactic Empire Seal were inkjet-printed at home, as well as some tactical markings on the flanks, puzzled together from single digits in "Aurebash", one of the Imperial SW languages/fonts.

For some variety and color highlights, dozens of small, round and colorful markings were die-punched from silver, yellow, orange, red and blue decal sheet and were placed all over the hull - together with the large panels they blur into the the overall appearance, though. The hatches received thin red linings, also made from generic decals strips.

 

The cockpit interior was a bit challenging, though. Good TIE Fighter cockpit interior pictures are hard to find, but they suggest a dark grey tone. More confusingly, the MPC instructions call for a “Dark Green” cockpit? Well, I did not like the all-grey option, since the spaceship is already monochrome grey on the outside.

 

As a compromise I eventually used Tamiya XF-65 "Field Grey". The interior recieved a black ink in and dry-brushing treatment, and some instruments ansd screens were created with black decal material and glossy black paint; some neon paint was used for sci-fi-esque conmtraol lamps everywhere - I did not pay too much intention on the interior, since the cockpit would stay closed, and the thick clear material blurs everything inside.

Following this rationale, the crew was also painted in arather minimal fashion - both wear a dark grey uniform, only the Chiss pilot stands aout with his light blue skin and the flourescent red eyes.

 

After an overall black ink wash the model received a dry brusing treatment with FS 36492 and FS 36495, for a weathered and battle-worn look. After all, the "Vehement" would not survive the Ballte of Endor, but who knows what became of TIE/E "801"'s mixed crew...?

Finally, the kit was sealed with matt acrylic varnish, and some final cosmetic corrections made.

 

The display is a DIY creation, too, made from a 6x6" piece of wood, it's edges covered with edgebonder, a steel wire as holder, and finally the display was paited with semi-matt black acrylic paint from the rattle can.

  

A complex build, and the TIE/E more or less evolved along the way, with only the overall layout in mind. Work took a month, but I think it was worth the effort. This fantasy creation looks pretty plausible and blends well into the vast canonical TIE Fighter family - and I am happy that I finally could finish this mummy project, including the surplus Jedi Starfighter kit which now also find a very good use!

 

An epic one, and far outside my standard comfort zone. But a wothwhile build!

Development studies at Grumman for jet-powered fighter aircraft began near the end of World War II as the first jet engines emerged. In a competition for a jet-powered night fighter for the United States Navy, on 3 April 1946 the Douglas F3D Skyknight was selected over Grumman's G-75, a two-seater powered by four Westinghouse J30s. The Navy's Bureau of Aeronautics (BuAer) also issued a contract to Grumman for two G-75 prototype aircraft on 11 April 1946, in case the Skyknight ran into problems.

However, Grumman soon realized that the G-75 was a dead end. But the company had been working on a completely different day fighter, the G-79, which offered a higher potential. In order to keep Grumman in the US Navy’s procurement loop, BuAer, in a bureaucratic maneuver, did not cancel the G-75 contract, but changed the wording to include prototypes of the entirely different G-79, too.

 

The G-79 project comprised a total of four different layouts and engine arrangements for a single seat fighter aircraft. G-79A and B were traditional tail sitters, but both featured mixed propulsion for an enhanced performance: G-79A was powered by an R-2800 radial engine and a Rolls Royce Derwent VI jet booster in the tail, fed by a pair of dorsal air intakes behind the cockpit. The G-79B was a similar aircraft, but its primary engine was a General Electric TG-100 turboprop in a more slender nose section. Even though both designs were big aircraft, initial calculations indicated a performance that would be superior to the Grumman F8F Bearcat, which had been designed as a thoroughbred interceptor.

 

The other two designs were pure jet fighters, both with a tricycle landing gear. G-79C had a layout reminiscent of the Gloster Meteor and was powered by two Derwent VI engines in bulky wing nacelles, and G-79D was finally an overall smaller and lighter aircraft, similar in its outlines to the early Vought F6U Pirate, and powered by a single Nene in the rear fuselage, fed by air intakes in the wing roots.

 

Since the operation of jet-powered aircraft from carriers was terra incognita for the US Navy, and early turbojets thirsty and slow to react to throttle input, BuAer decided to develop two of Grumman's G-79 designs into prototypes for real life evaluation: one of the conservative designs, as a kind of safe route, and one of the more modern jets.

From the mixed propulsion designs, the turboprop-powered G-79B was chosen (becoming the XF9F-1 'JetCat'), since it was expected to offer a higher performance and development potential than the radial-powered 'A'. From the pure jet designs the G-79D was chosen, because of its simplicity and compact size, and designated XF9F-2 'Panther'.

 

The first JetCat prototype made its maiden flight on 26 October 1947, but it was only a short airfield circuit since the TG-100 turpoprop failed to deliver full power and the jet booster had not been installed yet. The prototype Panther, piloted by test pilot Corky Meyer, first flew on 21 November 1947 without major problems.

 

In the wake of the two aircrafts' test program, several modifications and improvements were made. This included an equal armament of four 20mm guns (mounted in the outer, foldable wings on the JetCat and, respectively, in the Panther’s nose). Furthermore, both aircraft were soon armed with underwing HVAR air-to-ground rockets and bombs, and the JetCat even received an underfuselage pylon for the potential carriage of an airborne torpedo. Since there was insufficient space within the foldable wings and the fuselage in both aircraft for the thirsty jet’s fuel, permanently mounted wingtip fuel tanks were added on both aircraft, which incidentally improved the fighters' rate of roll. Both F9F types were cleared for flight from aircraft carriers in September 1949.

 

The F9F-1 was soon re-engined with an Allison T38 turboprop, which was much more reliable than the TF-100 (in the meantime re-designated XT31) and delivered a slightly higher power output. Another change was made for the booster: the bulky Derwent VI engine from the prototype stage was replaced by a much more compact Westinghouse J34 turbojet, which not only delivered slightly more thrust, it also used up much less internal space which was used for radio and navigation equipment, a life raft and a relocated oil tank. Due to a resulting CG shift towards the nose, the fuselage fuel cell layout had to be revised. As a consequence, the cockpit was moved 3’ backwards, slightly impairing the pilot’s field of view, but it was still superior to the contemporary Vought F4U.

 

Despite the engine improvements, though, the F9F-1 attained markedly less top speed than the F9F-2. On the other side, it had a better rate of climb and slow speed handling characteristics, could carry more ordnance and offered a considerably bigger range and extended loiter time. The F9F-2 was more agile, though, and more of the nimble dogfighter the US Navy was originally looking for. Its simplicity with just a single engine was appealing, too.

 

The Panther was eventually favored as the USN's first operational jet day fighter and put into production, but the F9F-1 showed much potential as a fast fighter bomber. Through pressure from the USMC, who was looking for a replacement for its F7F heavy Tigercat fighters, a production order for 50 JetCats was eventually placed, later augmented to 82 aircraft because the US Navy also recognized the type’s potential as a fast, ship-borne multi-role fighter. Further interest came in 1949 from Australia, when the country’s government was looking for a - possibly locally-built in license - replacement for the outdated Mustang Mk 23 and De Havilland Vampire then operated by the Royal Australian Air Force (RAAF). Both Grumman designs were potential contenders, rivalling with the domestic CAC CA-23 fighter development.

 

The Grumman Panther became the most widely used U.S. Navy jet fighter of the Korean War, flying 78,000 sorties and scoring the first air-to-air kill by the U.S. Navy in the war, the downing of a North Korean Yakovlev Yak-9 fighter. Being rugged aircraft, F9F-2s, -3s and -5s were able to sustain operations, even in the face of intense anti-aircraft fire. The pilots also appreciated the Panther’s air conditioned cockpit, which was a welcome change from the humid environment of piston-powered aircraft.

 

The F9F-1 did fare less glamorous. Compared with the prototypes, the T38 turboprop's power output could be enhanced on service aircraft, but not on a significant level. The aircraft's original, rather sluggish response to throttle input and its low-speed handling were improved through an eight-blade contraprop, which, as a side benefit, countered torque problems during starts and landings on carriers.

The JetCat’s mixed powerplant installation remained capricious, though, and the second engine and its fuel meant a permanent weight penalty. The aircraft's complexity turned out to be a real weak point during the type's deployment to front line airfields in the Korean War, overall readiness was – compared with conservative types like the F4U and also the F9F-2, low. Despite the turboprop improvements, the jet booster remained necessary for carrier starts and vital in order to take on the MiG-15 or post-war piston engine types of Soviet origin like the Lavochkin La-9 and -11 or the Yakowlev Yak-9.

 

Frequent encounters with these opponents over Korea confirmed that the F9F-1 was not a “naturally born” dogfighter, but rather fell into the escort fighter or attack aircraft class. In order to broaden the type's duty spectrum, a small number of USMC and USN F9F-1s was modified in field workshops with an APS-6 type radar equipment from F4U-4N night fighters. Similar to the Corsair, the radar dish was carried in a streamlined pod under the outer starboard wing. The guns received flame dampers, and these converted machines, re-designated F9F-1N, were used with mild success as night and all-weather fighters.

 

However, the JetCat remained unpopular among its flight and ground crews and, after its less-than-satisfactory performance against MiGs, quickly retired. After the end of the Korean War in July 1953, all machines were grounded and by 1954 all had been scrapped. However, the turboprop-powered fighter bomber lived on with the USMC, which ordered the Vought A3U SeaScorpion as successor.

The kit and its assembly:

This is another submission to the Cold War GB at whatifmodelers in early 2018, and rather a spontaneous idea. It was actually spawned after I finished my fictional Gudkov Gu-1 mixed propulsion fighter - while building (using the engine front from an F6F Hellcat) I had the impression that it could also have ended up as a post-war USN fighter design.

 

A couple of days later, while browsing literature for inspiration, I came across Grumman's G-79 series of designs that eventually led to the F9F Panther - and I was amazed that the 'A' design almost looked like my kitbashed Soviet fighter!

 

So I considered a repeated build of a P-47D/Supermarine Attacker kitbash, just in American colors. But with the F9F relationship, I planned the integration of Panther parts, so that the new creation would look different from the Gu-1, but also show some (more) similarity to the Panther.

 

The plan appeared feasible. Again, the aircraft's core is an Academy P-47D, with its outer wings cut off. Cockpit and landing gear were retained. However, instead of Supermarine Attacker wings from a Novo kit, I attached F9F-2 wings from a Hasegawa kit. Shape-wise this worked fine, but the Panther wings are much thinner than the Thunderbolt’s, so that I had to integrate spacers inside of the intersections which deepen the Hasegawa parts. Not perfect, but since the type would feature folding wings, the difference and improvisation is not too obvious.

 

On the fuselage, the Thunderbolt’s air outlets on its flanks were faired over and most of the tail section cut away. In the lower part of the tail, a jet pipe (from a Heller F-84G) was added and blended with PSR into the Thunderbolt fuselage, similar to the Gu-1. A completely new fin was scratched from an outer wing section from a Heinkel He 189, in an attempt to copy the G-79B's shape according to the drawing I used as benchmark for the build. I also used the F9F's stabilizers. With clipped tips they match well in size and shape, and add to the intended Grumman family look. The original tail wheel well was retained, but the tail wheel was placed as far back as possible and replaced by the twin wheel from a Hasegawa F5U. The Panther’s OOB tail hook was integrated under the jet pipe, too.

 

The front section is completely different and new, and my choice fell on the turboprop-powered G-79B because I did not want to copy the Gu-1 with its radial engine. However, the new turboprop nose was not less complicated to build. Its basis is a 1:100 engine and contraprop from a VEB Plasticart Tu-20/95 bomber, a frequent ingredient in my builds because it works so well in 1:72 scale. This slender core was attached to the Thunderbolt's fuselage, and around this basis a new cowling was built up with 2C putty, once more in an attempt to mimic the original G-79B design as good as possible.

 

In order to blend the new engine with the fuselage and come close to the G-79B’s vaguely triangular fuselage diameter, the P-47's deep belly was cut away, faired over with styrene sheet, and everything blended into each other with more PSR work. As a final step, two exhaust pipes were mounted to the lower fuselage in front of the wings’ leading edge.

 

The air intakes for the jet booster are actually segments from a Sopwith Triplane fuselage (Revell) – an unlikely source, but the shape of the parts was just perfect. More PSR was necessary to blend them into the aircraft’s flanks, though.

  

Painting and markings:

As per usual, I'd rather go with conservative markings on a fictional aircraft. Matching the Korean War era, the aircraft became all-over FS 35042 (Modelmaster). A black ink wash emphasized the partly re-engraved panel lines, and some post shading highlighted panels.

 

The wings’ leading edges and the turboprop’s intake were painted with aluminum, similar edges on fin and stabilizers were created with silver decal material. The interior of cockpit and landing gear was painted with green chromate primer.

 

The markings were puzzled together. “Stars and Bars” and VF-53 markings were taken from a Hobby Boss F4U-4 kit. The blue fin tip is the marking for the 3rd squadron, so that the “307” tactical code is plausible, too (the latter comes from a Hobby Boss F9F-2). In order to keep things subtle and more business-like (after all, the aircraft is supposed to be operated during the ongoing Korean War), I did not carry the bright squadron color to any other position like the spinner or the wing tips.

 

After some final detail work and gun and exhaust soot stains, the kit was sealed with semi-gloss acrylic varnish (Italeri). Matt acrylic varnish was used for weathering effects, so that the aircraft would not look too clean and shiny.

  

While it is not a prefect recreation of the Grumman G-79B, I am quite happy with the result. The differences between the model and the original design sketch can be explained through serial production adaptations, and overall the whole thing looks pretty conclusive. In fact, the model appears from certain angles like a naval P-51 on steroids, even though the G-79B was a much bigger aircraft than the Mustang.

Some background:

The РТАК-30 attack vintoplan (also known as vintokryl) owed its existence to the Mil Mi-30 plane/helicopter project that originated in 1972. The Mil Mi-30 was conceived as a transport aircraft that could hold up to 19 passengers or two tons of cargo, and its purpose was to replace the Mi-8 and Mi-17 Helicopters in both civil and military roles. With vertical takeoff through a pair of tiltrotor engine pods on the wing tips (similar in layout to the later V-22 Osprey) and the ability to fly like a normal plane, the Mil Mi-30 had a clear advantage over the older models.

 

Since the vintoplan concept was a completely new field of research and engineering, a dedicated design bureau was installed in the mid-Seventies at the Rostov-na-Donu helicopter factory, where most helicopters from the Mil design bureau were produced, under the title Ростов Тилт Ротор Авиационная Компания (Rostov Tilt Rotor Aircraft Company), or РТАК (RTRA), for short.

 

The vintoplan project lingered for some time, with basic research being conducted concerning aerodynamics, rotor design and flight control systems. Many findings later found their way into conventional planes and helicopters. At the beginning of the 1980s, the project had progressed far enough that the vintoplan received official backing so that РТАК scientists and Mil helicopter engineers assembled and tested several layouts and components for this complicated aircraft type.

At that time the Mil Mi-30 vintoplan was expected to use a single TV3-117 Turbo Shaft Engine with a four-bladed propeller rotors on each of its two pairs of stub wings of almost equal span. The engine was still installed in the fuselage and the proprotors driven by long shafts.

 

However, while being a very clean design, this original layout revealed several problems concerning aeroelasticity, dynamics of construction, characteristics for the converter apparatuses, aerodynamics and flight dynamics. In the course of further development stages and attempts to rectify the technical issues, the vintoplan layout went through several revisions. The layout shifted consequently from having 4 smaller engines in rotating pods on two pairs of stub wings through three engines with rotating nacelles on the front wings and a fixed, horizontal rotor over the tail and finally back to only 2 engines (much like the initial concept), but this time mounted in rotating nacelles on the wing tips and a canard stabilizer layout.

 

In August 1981 the Commission of the Presidium of the USSR Council of Ministers on weapons eventually issued a decree on the development of a flyworthy Mil Mi-30 vintoplan prototype. Shortly afterwards the military approved of the vintoplan, too, but desired bigger, more powerful engines in order to improve performance and weight capacity. In the course of the ensuing project refinement, the weight capacity was raised to 3-5 tons and the passenger limit to 32. In parallel, the modified type was also foreseen for civil operations as a short range feederliner, potentially replacing Yak-40 and An-24 airliners in Aeroflot service.

In 1982, РТАК took the interest from the military and proposed a dedicated attack vintoplan, based on former research and existing components of the original transport variant. This project was accepted by MAP and received the separate designation РТАК-30. However, despite having some close technical relations to the Mi-30 transport (primarily the engine nacelles, their rotation mechanism and the flight control systems), the РТАК-30 was a completely different aircraft. The timing was good, though, and the proposal was met with much interest, since the innovative vintoplan concept was to compete against traditional helicopters: the design work on the dedicated Mi-28 and Ka-50 attack helicopters had just started at that time, too, so that РТАК received green lights for the construction of five prototypes: four flyworthy machines plus one more for static ground tests.

 

The РТАК-30 was based on one of the early Mi-30 layouts and it combined two pairs of mid-set wings with different wing spans with a tall tail fin that ensured directional stability. Each wing carried a rotating engine nacelle with a so-called proprotor on its tip, each with three high aspect ratio blades. The proprotors were handed (i.e. revolved in opposite directions) in order to minimize torque effects and improve handling, esp. in the hover. The front and back pair of engines were cross-linked among each other on a common driveshaft, eliminating engine-out asymmetric thrust problems during V/STOL operations. In the event of the failure of one engine, it would automatically disconnect through torque spring clutches and both propellers on a pair of wings would be driven by the remaining engine.

Four engines were chosen because, despite the weight and complexity penalty, this extra power was expected to be required in order to achieve a performance that was markedly superior to a conventional helicopter like the Mi-24, the primary Soviet attack helicopter of that era the РТАК-30 was supposed to replace. It was also expected that the rotating nacelles could also be used to improve agility in level flight through a mild form of vectored thrust.

 

The РТАК-30’s streamlined fuselage provided ample space for avionics, fuel, a fully retractable tricycle landing gear and a two man crew in an armored side-by-side cockpit with ejection seats. The windshield was able to withstand 12.7–14.5 mm caliber bullets, the titanium cockpit tub could take hits from 20 mm cannon. An autonomous power unit (APU) was housed in the fuselage, too, making operations of the aircraft independent from ground support.

While the РТАК-30 was not intended for use as a transport, the fuselage was spacious enough to have a small compartment between the front wings spars, capable of carrying up to three people. The purpose of this was the rescue of downed helicopter crews, as a cargo hold esp. for transfer flights and as additional space for future mission equipment or extra fuel.

In vertical flight, the РТАК-30’s tiltrotor system used controls very similar to a twin or tandem-rotor helicopter. Yaw was controlled by tilting its rotors in opposite directions. Roll was provided through differential power or thrust, supported by ailerons on the rear wings. Pitch was provided through rotor cyclic or nacelle tilt and further aerodynamic surfaces on both pairs of wings. Vertical motion was controlled with conventional rotor blade pitch and a control similar to a fixed-wing engine control called a thrust control lever (TCL). The rotor heads had elastomeric bearings and the proprotor blades were made from composite materials, which could sustain 30 mm shells.

 

The РТАК-30 featured a helmet-mounted display for the pilot, a very modern development at its time. The pilot designated targets for the navigator/weapons officer, who proceeded to fire the weapons required to fulfill that particular task. The integrated surveillance and fire control system had two optical channels providing wide and narrow fields of view, a narrow-field-of-view optical television channel, and a laser rangefinder. The system could move within 110 degrees in azimuth and from +13 to −40 degrees in elevation and was placed in a spherical dome on top of the fuselage, just behind the cockpit.

 

The aircraft carried one automatic 2A42 30 mm internal gun, mounted semi-rigidly fixed near the center of the fuselage, movable only slightly in elevation and azimuth. The arrangement was also regarded as being more practical than a classic free-turning turret mount for the aircraft’s considerably higher flight speed than a normal helicopter. As a side effect, the semi-rigid mounting improved the cannon's accuracy, giving the 30 mm a longer practical range and better hit ratio at medium ranges. Ammunition supply was 460 rounds, with separate compartments for high-fragmentation, explosive incendiary, or armor-piercing rounds. The type of ammunition could be selected by the pilot during flight.

The gunner can select one of two rates of full automatic fire, low at 200 to 300 rds/min and high at 550 to 800 rds/min. The effective range when engaging ground targets such as light armored vehicles is 1,500 m, while soft-skinned targets can be engaged out to 4,000 m. Air targets can be engaged flying at low altitudes of up to 2,000 m and up to a slant range of 2,500 m.

 

A substantial range of weapons could be carried on four hardpoints under the front wings, plus three more under the fuselage, for a total ordnance of up to 2,500 kg (with reduced internal fuel). The РТАК-30‘s main armament comprised up to 24 laser-guided Vikhr missiles with a maximum range of some 8 km. These tube-launched missiles could be used against ground and aerial targets. A search and tracking radar was housed in a thimble radome on the РТАК-30’s nose and their laser guidance system (mounted in a separate turret under the radome) was reported to be virtually jam-proof. The system furthermore featured automatic guidance to the target, enabling evasive action immediately after missile launch. Alternatively, the system was also compatible with Ataka laser-guided anti-tank missiles.

Other weapon options included laser- or TV-guided Kh-25 missiles as well as iron bombs and napalm tanks of up to 500 kg (1.100 lb) caliber and several rocket pods, including the S-13 and S-8 rockets. The "dumb" rocket pods could be upgraded to laser guidance with the proposed Ugroza system. Against helicopters and aircraft the РТАК-30 could carry up to four R-60 and/or R-73 IR-guided AAMs. Drop tanks and gun pods could be carried, too.

 

When the РТАК-30's proprotors were perpendicular to the motion in the high-speed portions of the flight regime, the aircraft demonstrated a relatively high maximum speed: over 300 knots/560 km/h top speed were achieved during state acceptance trials in 1987, as well as sustained cruise speeds of 250 knots/460 km/h, which was almost twice as fast as a conventional helicopter. Furthermore, the РТАК-30’s tiltrotors and stub wings provided the aircraft with a substantially greater cruise altitude capability than conventional helicopters: during the prototypes’ tests the machines easily reached 6,000 m / 20,000 ft or more, whereas helicopters typically do not exceed 3,000 m / 10,000 ft altitude.

 

Flight tests in general and flight control system refinement in specific lasted until late 1988, and while the vintoplan concept proved to be sound, the technical and practical problems persisted. The aircraft was complex and heavy, and pilots found the machine to be hazardous to land, due to its low ground clearance. Due to structural limits the machine could also never be brought to its expected agility limits

During that time the Soviet Union’s internal tensions rose and more and more hampered the РТАК-30’s development. During this time, two of the prototypes were lost (the 1st and 4th machine) in accidents, and in 1989 only two machines were left in flightworthy condition (the 5th airframe had been set aside for structural ground tests). Nevertheless, the РТАК-30 made its public debut at the Paris Air Show in June 1989 (the 3rd prototype, coded “33 Yellow”), together with the Mi-28A, but was only shown in static display and did not take part in any flight show. After that, the aircraft received the NATO ASCC code "Hemlock" and caused serious concern in Western military headquarters, since the РТАК-30 had the potential to dominate the European battlefield.

 

And this was just about to happen: Despite the РТАК-30’s development problems, the innovative attack vintoplan was included in the Soviet Union’s 5-year plan for 1989-1995, and the vehicle was eventually expected to enter service in 1996. However, due to the collapse of the Soviet Union and the dwindling economics, neither the РТАК-30 nor its civil Mil Mi-30 sister did soar out in the new age of technology. In 1990 the whole program was stopped and both surviving РТАК-30 prototypes were mothballed – one (the 3rd prototype) was disassembled and its components brought to the Rostov-na-Donu Mil plant, while the other, prototype No. 1, is rumored to be stored at the Central Russian Air Force Museum in Monino, to be restored to a public exhibition piece some day.

The kit and its assembly:

This exotic, fictional aircraft-thing is a contribution to the “The Flying Machines of Unconventional Means” Group Build at whatifmodelers.com in early 2019. While the propulsion system itself is not that unconventional, I deemed the quadrocopter concept (which had already been on my agenda for a while) to be suitable for a worthy submission.

The Mil Mi-30 tiltrotor aircraft, mentioned in the background above, was a real project – but my alternative combat vintoplan design is purely speculative.

 

I had already stashed away some donor parts, primarily two sets of tiltrotor backpacks for 1:144 Gundam mecha from Bandai, which had been released recently. While these looked a little toy-like, these parts had the charm of coming with handed propellers and stub wings that would allow the engine nacelles to swivel.

The search for a suitable fuselage turned out to be a more complex safari than expected. My initial choice was the spoofy Italeri Mi-28 kit (I initially wanted a staggered tandem cockpit), but it turned out to be much too big for what I wanted to achieve. Then I tested a “real” Mi-28 (Dragon) and a Ka-50 (Italeri), but both failed for different reasons – the Mi-28 was too slender, while the Ka-50 had the right size – but converting it for my build would have been VERY complicated, because the engine nacelles would have to go and the fuselage shape between the cockpit and the fuselage section around the original engines and stub wings would be hard to adapt. I eventually bought an Italeri Ka-52 two-seater as fuselage donor.

 

In order to mount the four engines to the fuselage I’d need two pairs of wings of appropriate span – and I found a pair of 1:100 A-10 wings as well as the wings from an 1:72 PZL Iskra (not perfect, but the most suitable donor parts I could find in the junkyard). On the tips of these wings, the swiveling joints for the engine nacelles from the Bandai set were glued. While mounting the rear wings was not too difficult (just the Ka-52’s OOB stabilizers had to go), the front pair of wings was more complex. The reason: the Ka-52’s engines had to go and their attachment points, which are actually shallow recesses on the kit, had to be faired over first. Instead of filling everything with putty I decided to cover the areas with 0.5mm styrene sheet first, and then do cosmetic PSR work. This worked quite well and also included a cover for the Ka-52’s original rotor mast mount. Onto these new flanks the pair of front wings was attached, in a mid position – a conceptual mistake…

 

The cockpit was taken OOB and the aircraft’s nose received an additional thimble radome, reminiscent of the Mi-28’s arrangement. The radome itself was created from a German 500 kg WWII bomb.

 

At this stage, the mid-wing mistake reared its ugly head – it had two painful consequences which I had not fully thought through. Problem #1: the engine nacelles turned out to be too long. When rotated into a vertical position, they’d potentially hit the ground! Furthermore, the ground clearance was very low – and I decided to skip the Ka-52’s OOB landing gear in favor of a heavier and esp. longer alternative, a full landing gear set from an Italeri MiG-37 “Ferret E” stealth fighter, which itself resembles a MiG-23/27 landing gear. Due to the expected higher speeds of the vintoplan I gave the landing gear full covers (partly scratched, plus some donor parts from an Academy MiG-27). It took some trials to get the new landing gear into the right position and a suitable stance – but it worked. With this benchmark I was also able to modify the engine nacelles, shortening their rear ends. They were still very (too!) close to the ground, but at least the model would not sit on them!

However, the more complete the model became, the more design flaws turned up. Another mistake is that the front and rear rotors slightly overlap when in vertical position – something that would be unthinkable in real life…

 

With all major components in place, however, detail work could proceed. This included the completion of the cockpit and the sensor turrets, the Ka-52 cannon and finally the ordnance. Due to the large rotors, any armament had to be concentrated around the fuselage, outside of the propeller discs. For this reason (and in order to prevent the rear engines to ingest exhaust gases from the front engines in level flight), I gave the front wings a slightly larger span, so that four underwing pylons could be fitted, plus a pair of underfuselage hardpoints.

The ordnance was puzzled together from the Italeri Ka-52 and from an ESCI Ka-34 (the fake Ka-50) kit.

  

Painting and markings:

With such an exotic aircraft, I rather wanted a conservative livery and opted for a typical Soviet tactical four-tone scheme from the Eighties – the idea was to build a prototype aircraft from the state acceptance trials period, not a flashy demonstrator. The scheme and the (guesstimated) colors were transferred from a Soviet air force MiG-21bis of that era, and it consists of a reddish light brown (Humbrol 119, Light Earth), a light, yellowish green (Humbrol 159, Khaki Drab), a bluish dark green (Humbrol 195, Dark Satin Green, a.k.a. RAL 6020 Chromdioxidgrün) and a dark brown (Humbrol 170, Brown Bess). For the undersides’ typical bluish grey I chose Humbrol 145 (FS 35237, Gray Blue), which is slightly lighter and less greenish than the typical Soviet tones. A light black ink wash was applied and some light post-shading was done in order to create panels that are structurally not there, augmented by some pencil lines.

 

The cockpit became light blue (Humbrol 89), with medium gray dashboard and consoles. The ejection seats received bright yellow seatbelts and bright blue pads – a detail seen on a Mi-28 cockpit picture.

Some dielectric fairings like the fin tip were painted in bright medium green (Humbrol 101), while some other antenna fairings were painted in pale yellow (Humbrol 71).

The landing gear struts and the interior of the wells became Aluminum Metalic (Humbrol 56), the wheels dark green discs (Humbrol 30).

 

The decals were puzzled together from various sources, including some Begemot sheets. Most of the stencils came from the Ka-52 OOB sheet, and generic decal sheet material was used to mark the walkways or the rotor tips and leading edges.

 

Only some light weathering was done to the leading edges of the wings, and then the kit was sealed with matt acrylic varnish.

  

A complex kitbashing project, and it revealed some pitfalls in the course of making. However, the result looks menacing and still convincing, esp. in flight – even though the picture editing, with four artificially rotating proprotors, was probably more tedious than building the model itself!

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:

A vanship is a type of flying machine from the animated series Last Exile. It is often referred to as a "flying boat" in that it does not fly by means of aerodynamics like planes do, but rather by floating on the air and propelling itself through the use of a substance known as "Claudia" (see below).

 

Vanships in general were couriers prior to the events of Last Exile, traveling long distances to deliver cargoes (usually messages). Some Vanships thus include tools for towing solid objects.

 

The design of several vanships throughout the series bears great resemblance to various famed 1930s racecars than any aircraft, most notably the Anatoray millitary vanships which bear great resemblance to the 1933 Napier Railton. The resemblance is found in the grill shape of the cowl vents and the shape of the tail cone, as well as the aerodynamic bulges on the car which cover the valve covers and exaust on the car, which are also found on the Anatoray vanships.

Other Vanships bear striking design elements from Junkers aircraft in the pre-WWII era, e. g. from the A 35 monoplane.

 

"Spirit of Grand Stream" is a courier-type vanship (see below) owned by Claus Valca and Lavie Head, and its design is very similar to that of Hayao Miyazaki's gunship from Nausicaa of the Valley of the Wind. The matches are really focused on the two seated open cockpit, and the navigator section which has matching interface panels of small glass cylinders.

Courier vanships, also known as racing vanships, are one of the main types of vanship featured in Last Exile. Courier vanships are small and narrow with a single, high-powered thruster. Like any vanship intended to achieve high speeds, they have stub wings, far too small themselves to provide lift. They simply act as mounts for ailerons to provide better steering, as pivoting the thruster would put undue stress on the assembly at high speeds.

 

Over the course of Last Exile, Vanships were adapted for combat. The process resembles the evolving roles that aircraft held during WW1; originally developed for scouting and surveillance, but eventually equipped with bombs and machine guns to become potent fightercraft.

 

Claudia is a fluorescent blue ore mined on the floating world of Prester. It is the foundation of Prester's technology, fueling steam engines and is a key element of the claudia units that allow vanships to fly. Claudia is also the primary currency of Prester. It is well suited for the purpose, as it is constantly generated by Prester and is not possible to counterfeit.

Claudia, when dissolved in water, serves as the primary drive fluid in a claudia unit. When Claudia fluid is heated and compressed, it generates lift. A vanship engine has a distinctive claudia circulation pipe loop, where the supercritical fluid generates both lift and thrust.

 

Dissolving Claudia in alcohol dramatically increases the energy density of the fuel. This is why steam engines are the predominant technology of Last Exile, instead of the internal combustion engine. Technology design documents from the production of the show indicate that the steam engines of Last Exile have a power to weight ratio exceeding that of a modern gasoline fueled internal combustion engine.

 

All vanships in the series were rendered as 3D images, a hallmark of Japanese animation studio Gonzo, makers of such series as Vandread and Blue Submarine No. 6.

  

The kit and its assembly:

I love the Vanships from Last Exile - even though I have never seen the series.

While these vehicles appear as retro stuff, they are very original and unique in look and feel - a modeler's dream if you are into scratchbuilding and kitbashing. There's also a 1:72 Vanship kit available (actually, in two versions) from Hasegawa, but it is IMHO overpriced. And there are so many different Vanships in the series that it is a shame that not more of them have been kitted, scratched, or at least used as a source of modelling inspiration.

 

The latter's the case here. I had a scratched Vanship on the agenda for a long time and also a basic idea with what I'd start, but it took a SF racing GB at phoxim.de (a German SF model building forum) to make a move.

 

I wanted a small and fast single seater, and this evolved through the GB into a Racer with a more prominent engine unit and a rather purposeful livery instead of bright colors. But the basic concept was retained: originally, the plan was to use a 1:72 F4U as fuselage basis, and I had the idea to integrate some parts of a 1:43 Citroen 11CV from Heller, e. g. its grill and bonnet.

 

The F4U is the SMER kit, and it has the benefit of having separate wings for a folded display. The fin was cut off and the landing gear wells covered.

The cockpit opening was slightly enlarged in order to take a 1:48 Japanese WWII resin pilot and a seat from the 1:43 11CV - pretty cramped, but it worked and looks good. Only the wind screen of the OOB F4U canopy was used, as well as the original dashboard.

 

Most work was done on the outside, though. The first problem turned up when I realized that the 11CV bonnet could hardly be mated with the F4U. As a plan B I found a cover for the brush head of a Philipps electric toothbrush in my donor bank - a bit too high and narrow, but overall a unique addition and characteristic nose for my creation!

 

The landing gear comes from an Amodel Ju-87A - together with the drooped F4U inner wings the result looked a bit stalky at first, but the Vanship still needed its engines.

 

As a racer, I went for double power, and the long pods that carry the propulsion system were scratched from several non-model-kit parts:

- Front comes from a Revell 1:32 AH-64 Apache, its engines

- The intakes come from a Matchbox Gloster Meteor NF.14

- The "ring" consists of wheel parts from the Heller 11CV

- The conic isolators are ball pen grips, cut to size and closed with tank wheels on both ends

- The fins are plastic knives, primarily the blades and parts of the handles

 

In between these engine pods, which are only held under the wings and stabilized internally through steel wire, a generator pod from a 1:72 Matchbox EA-6B fills the void. It also holds a characteristic "knife" under the front grill - again carved from the handle of the plastic knives.

 

In order to blend the changes in fuselage shape and diameter and create a kind of Cord-style grill I added three styrene strips which were wrapped around the nose, the upper line reaching back to the cockpit - a kind of 3D rally stripe that also streches the shape.

 

Some air scoops and surface details were added, made from styrene, and stiff cable was used under the front fuselage to create hoses between the bonnet with the Claudia reactor and the engines.

 

I was frequently tempted to add more things and details or decoration, but found that a rather clean look would better suit a dedicated racer Vanship - the Stutz Blackhawk land speed record car was a vague benchmark.

  

Painting and markings:

I wanted to keep things simple and dry. Before this turned into a racer I considered several colors like pale blue, a greyish-green, British Racing Green or Crimson, with ivory trim. Anyway, I rejected this in favir of a pure, bare metal finish. I even did not add colorful stripes - the only "color" comes from the mechanical parts (ivory and dark brown on the engine pods, the idea was to add an isolator impression) and the small sponsor decals.

 

The kit initially received a basic coat of Revell's acrylic Aluminum, and onto that panels/field with several Metallizer tones (Steel, Magnesium, Titanium, polished Aluminum) were added. On top of that, the whole thing received a rubbing with grinded graphite - intensifying the metal shine and also weathering the vehicle.

 

The pilot received a rather conservatie outfit, with a brown leather jacket - matching the overall style of the Vanship. Some engine parts (e. g. the blades and the knife under the nose) were painted with a mix of Steel Metallizer and Gold. The cockpit interior was painted in RLM 02.

 

The markings were puzzled together. The start number '24' in that nice retro type comes from an 1:72 Airfix Il-2, the black disc below is from a slot car aftermarket sheet. The many sponsor stickers come mostly from an 1:72 Su-27 demonstrator aircraft sheet from Begemot - with their cyrillic typo they blend well into the Last Exile look and feel (where Greek/Cyrillic typo pops up).

 

Finally, the kit received a coat with acrylic gloss varnish, while the anti glare panel in front of the windscreen became matt.

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?

Some background:

The Republic P-47 Thunderbolt was one of the largest and heaviest fighter aircraft in history to be powered by a single piston engine. It was heavily armed with eight .50-caliber machine guns, four per wing. When fully loaded, the P-47 weighed up to eight tons, and in the fighter-bomber ground-attack roles could carry five-inch rockets or a significant bomb load of 2,500 pounds; it could carry over half the payload of the B-17 bomber on long-range missions (although the B-17 had a far greater range).

 

The P-47, originally based on the powerful Pratt & Whitney R-2800 Double Wasp engine, was to be very effective as a short-to-medium range escort fighter in high-altitude air-to-air combat and, when unleashed as a fighter-bomber, proved especially adept at ground attack in both the World War II European and Pacific Theaters.

The P-47 was one of the main United States Army Air Forces (USAAF) fighters of World War II, and served with other Allied air forces, notably those of France, Britain, and Russia. Mexican and Brazilian squadrons fighting alongside the U.S. were equipped with the P-47.

 

In 1943, two P-47D-15-RE airframes (serials 42-23297/23298) were selected for testing with the new experimental 2300 hp Chrysler XIV-2220-1 sixteen-cylinder inverted Vee liquid-cooled engine. These aircraft were re-designated XP-47H. The liquid-cooled Chrysler engine with its large under-fuselage radiator radically changed the appearance of the Thunderbolt, and increased overall length to 39 feet 2 inches. With the increased power and improved streamlining, a maximum speed of 490 mph was anticipated.

 

The two P-47D-15-RE airframes were converted until early 1944 and test flights began on July 26, 1945. During flight trails, one of the XP-47Hs actually attained a speed of 490 mph in level flight, and the new aircraft was primarily intended as a fast interceptor for the European theater, where especially Great Britain was endangered by the fast V1 missiles, and initial reports about German jet fighters and reconnaissance aircraft that were hard to counter with current piston-engine types, stirred the need for this fast aircraft.

 

Production P-47Hs received several amendments that had already been introduced with the late D types, e. g. the lowered back and a bubble canopy that offered excellent view. The P-47H also received the new wing from the P-47N, recognizable by its characteristic square wing tips which allowed better roll manoeuvers. Not visible at first glance were the integral wing tanks, which enhanced the internal fuel load to 4.792,3 liters, resulting in a range of 3.500 km (2.175 ml), so that the P-47H was also suited for long range bomber escorts. Air brakes were added to the wing's lower surfaces, too, to allow braking after a dive onto its prey.

Furthermore, serial production machines received an uprated, more reliable Chrysler XIV-2220-2 engine, which had an output of 2.450 hp.

 

The P-47H was put into limited production with 130 built, sufficient for one group. However, the type suffered serious teething problems in the field due to the highly tuned engine. Engines were unable to reach operating temperatures and power settings and frequently failed in early flights from a variety of causes: ignition harnesses cracked at high altitudes, severing electrical connections between the magneto and distributor, and carburetor valve diaphragms also failed. Poor corrosion protection during shipments across the Atlantic also took their toll on the engines and airframes.

 

By the time the bugs were worked out, the war in Europe was nearly over. However, P-47Hs still destroyed 15 enemy jet aircraft in aerial combat in March-May 1945 when aerial encounters with the Luftwaffe were rare. The type also proved itself to be a valuable V1 missile interceptor over the Channel.

 

The entire production total of 130 P-47Hs were delivered to the 358th Fighter Group, which was part of the 9th Air Force and operated from Great Britain, France and finally on German ground. From the crews the P-47H received several nicknames like 'torpedo', 'Thunderbullet' or 'Anteater', due to its elongated nose section.

 

Twelve P-47H were lost in operational crashes with the 358th Group resulting in 11 deaths, two after VE Day, and two (44-21134 on 13 April 1945 and 44-21230 on 16 April 1945) were shot down in combat, both by ground fire.

The kit and its assembly:

I had the (X)P-47H on the agenda for some time, and even the respective MPM kit stashed away. But it took some time to start this project - one reason actually being the, well, crudeness of the MPM offering. Anyway, I wanted to build a service aircraft, and I wondered how this would have looked like, way beyond 1944? That brought me towards the late bubble canopy versions of the P-47D - and suddenly the idea was born to convert the XP-47H into a respective service aircraft which would not only carry the Chrysler XIV-2220-1 V16 engine, but also other improvements of the type. This eventually led to the decision to make this build a kitbash, as a spine implantation would be the easiest way to incorporate the lowered back - or so I thought...

 

I chose the ancient Heller P-47(N) as donation kit. Not because it was “good”, it just had the right ingredients and was cheap and easy to procure. What sounded like a simple plan turned into a twisted route to vague success. I took the front fuselage and the lower belly from the MPM kit, as well as the horizontal stabilizers and mated it with the upper and rear fuselage of the Heller Thunderbolt. This could have been easy, if both kits would not have had different fuselage diameters - the Heller kit is about 1mm too narrow, even though the length is fine. In order to compensate, I built two new fuselage halves from the salvaged pieces, and once these were stable and more or less sanded even, put together. Inside, the cockpit was taken from the Heller kit, but the seat comes from the MPM kit, and a pilot figure was added. Another problem is the fact that the MPM kit features engraved panel lines, while the Heller kit has old school, raised details and lots of rivets.

The propeller from the MPM kit is a joke, so I built a replacement from scratch - from a drop tank front half from an ancient Revell F4U, and the individual propeller blades were taken from an Italeri F4U. Inside the fuselage, a styrene tube was implanted which holds the new propeller on a metal axis, so it can spin freely.

 

Other personal mods include lowered flaps and the large cooler intake was opened, with foamed styrene placed inside which mimics some mesh. The same method was also used inside of the intercooler outlets (primarily in order to block any light from shining through). Inside of the landing gear wells I added some structure made from styrene profiles.

 

Another bigger challenge was the wing attachment - Heller and MPM kit differ considerably in this aspect, so that swapping parts is not easy. The MPM kit has the wing roots molded onto the fuselage halves, while the Heller wings are, more or less, directly attached to the fuselage. As a consequence the Heller wings hold the complete landing gear wells, while the MPM solution has divided sections. I decided to get rid of the MPM wing roots, about 3mm of material, and onto these stubs the Heller wings were attached. The landing gear came from the Heller kit, but the main wheels come from a (new) Revell Me 262 - both MPM and Heller parts are not recommended for serious use... Finally, the many exhausts and cooler flaps were either sanded away and replaced by scratched parts, or added - e. g. the vents behind the cockpit. While the Heller kit features bomb and missile hardpoints under the wings I decided to leave them away - this is supposed to be a fast interceptor, not a train-hunting plough.

  

Painting and markings:

As this was to be a very late WWII aircraft, NMF was certain, and I wanted to place the service P-47H into the European conflict theatre, where its speed would IMHO be best used against German jet threats. I wanted a colorful aircraft, though, and settled for a machine of the 358th FG. This group actually flew Thunderbolts in the 365-367th Squadrons, and I found several profiles of these gaudy things.

Common to all of them was an orange tail and a dark blue back, while the engine cowling would be decorated with a red front and the air outlets would carry bands in red, white and blue, with lots of tiny stars sprinkled upon. Furthermore, I found specimen with white cowlings behind the red front end, or even yellow cowlings. Pretty cool.

 

I tried to mimic this look. The model was basically painted with Aluminum Metallizer (Humbrol 27002) overall. The effect is really good, even without rubbing treatment. Some panels were contrasted with Aluminium Plate and Polished Steel Metallizer (Modelmaster), as well as with Aluminum (Humbrol 56, which is rather a metallic grey). The latter was also used on the landing gear. The anti-glare panel in front of the cockpit was painted with Olive Drab (ANA 613 from Modelmaster).

 

Since there is no air intake opening on the inline engine I decided to paint the spinner in bright red (Humbrol 19), and tried to incorporate the white and blue theme with stars decoration to the rest of the nose. As a convenient coincidence, I found decals from an Italeri B-66 in the stash: it features a version with dark blue jet air intake decorations in the right size, colors and style for what I had been looking for. So, instead of painting everything by hand I decided to incorporate this decal option.

The area behind the spinner was painted white and then the B-66 decals applied to the front flanks. The radiator air intake scoop had to be cut out, but the overall size and shape were a very good match. Even the transition into the blue spine and cockpit area worked well!

The tail was painted with Humbrol 18, later some shading with Humbrol 82 was added. The blue spine was done with a mix of Humbrol 104 and 15 (Oxford Blue and Midnight Blue) - not a perfect match for the B-66 decal colors, but after some dirt and weathering these differences would blur.

 

Cockpit interior was painted in Humbrol 159 (Khaki Drab) and Zinc Chromate Green from Model Master. The landing gear wells received a chrome yellow primer (Humbrol 225 - actually RAF Mid Stone but a perfect match for the task) finish.

 

For weathering the kit received a rubbing treatment with grinded graphite, which adds a dark, metallic shine and emphasizes the kit’s raised panel lines. Some dry painting with Aluminum was added, too, simulating chipped paint on the leading edges. I also added some oil stains around the engine, and serious soot stains at the exhaust.

 

Decals were, beyond the B-66 decoration, puzzled together. The aircraft' code 'CH-F[bar]' is another exotic twist, in two ways. The bar under the letter marks a second use of that code within the squadron, and as a difference from normal code placement (normally exclusively on the fuselage) I placed the aircraft's individual code letter on the fin, a practice on some P-51s and a consequence of the relatively large letter decals.

 

The nose art is a fictional puzzle, consisting of a Czech MiG-21 pin-up from the Pardubice '89 meeting. The “Ohio Express” tag comes from a Tamiya 1:100 F-105 Thunderchief. A neat combination that even matches the overall colors well!

 

As a final step, a coat of semi matt acrylic varnish was applied, with the exception of the anti glare panel, which became purely matt.

  

A better XP-47H? Hard to tell, since this kitbashing was a messy and rather crude work, so the overall finish does not look as good as I hoped for. But the lowered spine and the fin root extension adds to a fast look of this thing, more elegant (if that's possible in this case?) than the Razorback prototypes. I can't help, but the finished article looks like an Evel Knievel stunt vehicle? The red spinner looks a bit odd, but I'll leave it this way.

Some background:

The Soviet Laboratory of High-Speed Automobiles (LSA ChADI, today the Chardiv National Automobile and Highway University) was founded in 1953. One of the laboratory’s founders was Vladimir Nikitin, a famous racer not only inside the Soviet Union but also around the world. The main purpose of Vladimir Nikitin’s of was to build the fastest car in the world. This idea of creating race cars became the purpose of the laboratory and has been continued by students of Nikitin throughout the years, with research and prototypes in various fields of car propulsion.

 

The first car created in LSA by students was ChADI 2 in 1961. The body of the car was made of fiberglass, the first time that this material was used for a car body in the Soviet Union. This technology was improved and later used in mass-produced cars. Another famous LSA car was ChADI 7. To create it, Nikitin and his students used airplane wing elements as car body material and used the engine from a helicopter to power it. The highest speed of ChADI 7 – 400 kilometers per hour – was recorded on an airport runway near Chardiv in 1968, and it was at that time the fastest car in the Soviet Union, setting the national land speed record.

 

After this successful vehicle, Vladimir Nikitin started a new, even more ambitious project: a speed record car with the jet engine from a high performance airplane! The name of this project was ChADI 9, and it was ambitious. This time Nikitin and his team used a Tumansky RD-9 turbojet engine with a dry thrust of 25.5 kN (5,730 lbf), the same engine that powered the supersonic Mikoyan-Gurewich MiG-19 fighter plane. He expected that this needle-shaped car would be able to break the absolute land speed record, which meant supersonic speed at level zero of almost 1.200 kilometers an hour. The car was finished in 1981, but unfortunately ChADI 9 never participated in any race and no official top speed result was ever recorded. This had initially a very practical reason: in the 1980’s there were simply no tires in the USSR that could be safely used at the expected speeds in excess of 400 km/h, and there was furthermore no track long enough for a serious test drive in the Soviet Union! In consequence, ChADI 9 had to be tested on the runway of a military airport in the proximity of Chardiv, outfitted with wheels and tires from a MiG-19, but these were not ideal for prolonged high speeds. Film footage from these tests later appeared in a 1983 movie called “IgLa”.

The Automotive Federation of the United States even invited ChADI 9 to participate in an official record race in the USA, but this did not happen either, this time for political reasons. Nevertheless, the main contribution of this car was gathering experience with powerful jet engines and their operations in a ground vehicle, as well as experience with car systems that could withstand and operate at the expected high levels of speed, and the vehicle was frequently tested until it was destroyed in high speed tests in 1988 (see below).

 

ChADI 9 was not the end of Nikitin’s strife for speed (and the prestige associated with it). The know-how that the design team had gathered in the first years of testing ChADI 9 were subsequentially integrated into the LSA’s ultimate proposal not only to break the national, but also the absolute land speed record: with a new vehicle dubbed ChADI 9-II. This car was a completely new design, and its name was deliberately chosen in order to secure project budgets – it was easier to gain support for existing (and so far successful) projects rather than found new ones and convince superior powers of their value and success potential.

 

ChADI 9-II’s conceptual phase was launched in 1982 and it was basically a scaled-up evolution of ChADI 9, but it featured some significant differences. Instead of the RD-9 turbojet, the new vehicle was powered by a much more potent Tumansky R-25-300 afterburning turbojet with a dry thrust of 40.21 kN (9,040 lbf) and 69.62 kN (15,650 lbf) with full afterburner. This new engine (used and proven in the MiG-21 Mach 2 fighter) had already been thoroughly bench-tested by the Soviet Laboratory of High-Speed Automobiles in 1978, on an unmanned, tracked sled.

However, the development of ChADI 9-II and its details took more than two years of dedicated work by LSA ChADI’s students, and in 1984 the design was finally settled. The new vehicle was much bigger than its predecessor, 44 ft 10 in long, 15 ft 6¾ in wide, and 9 ft 10¾ in high (13.67 m by 4,75 m by 3,02 m), and it weighed around 9,000 lb (4 t). Its construction was based on a steel tube frame with an integrated security cell for the driver and an aluminum skin body, with some fibre glass elements. While ChADI 9’s slender cigar-shaped body with a circular diameter and the tricycle layout were basically retained, the front end of ChADI 9-II and its internal structure were totally different: instead of ChADI 9’s pointed nose, with the cockpit in the front and ahead of the vehicle’s front wheel and a pair of conformal (but not very efficient) side air intakes, ChADI 9-II featured a large, single orifice with a central shock cone. A small raked lower lip was to prevent FOD to the engine and act at the same time as a stabilizing front spoiler. The driver sat under a tight, streamlined canopy, the bifurcated air intake ducts internally flanking the narrow cockpit. Two steerable front wheels with a very narrow track were installed in front of the driver’s compartment. They were mounted side by side on a central steering pylon, which made them look like a single wheel. Behind the cockpit, still flanked by the air ducts, came two fuel tanks and finally, after a chamber where the air ducts met again, the engine compartment. Small horizontal stabilizers under the cockpit, which could be adjusted with the help of an electric actuator, helped keeping the vehicle’s nose section on the ground. Two small air brakes were mounted on the rear fuselage; these not only helped to reduce the vehicle’s speed, they could also be deployed in order to trim the aerodynamic downforce on the rear wheels. The latter ware carried on outriggers for a wide and stable track width and were covered in tight aerodynamic fairings, again made from fibre glass. The outriggers were furthermore swept back far enough so that the engine’s nozzle was placed in front of the rear wheel axis. This, together with a marked “nose-down” stance as well as a single swept fin on the rear above the afterburner nozzle with a brake parachute compartment, was to ensure stability and proper handling at expected speeds far in excess of 600 km/h (372 mph) without the use of the engine’s afterburner, and far more at full power.

 

Construction of ChADI 9-II lasted for more than another year, and in May 1986 the vehicle was rolled out and ready for initial trials at Chardiv, this time on the Chardiv State Aircraft Manufacturing Company’s runway. These non-public tests were successful and confirmed the soundness of the vehicle’s concept and layout. In the course of thorough tests until July 1987, ChADI 9-II was carefully pushed beyond the 400 km/h barrier and showed certain potential for more. This was the point when the vehicle was presented to the public (it could not be hidden due to the noisy trials within Chardiv’s city limits), and for this occasion (and marketing purposes) ChADI 9-II received a flashy livery in silver with red trim around the air intake and long the flanks and was officially christened with the more catchy title “„скорость“” (Skorost = Velocity).

 

Meanwhile, a potential area for serious high-speed trials had been identified with Lake Baskunchak, a salt sea near the Caspian Sea with flat banks that resembled the Bonneville Salt Flats in the USA. Lake Baskunchak became the site of further tests in 1988. Initially scheduled for May-July, the tests had to be postponed by six weeks due to heavy rain in the region, so that the sea would not build suitable dry salt banks for any safe driving tests. In late June the situation improved, and „скорость“ could finally take up its high speed tests.

 

During the following weeks the vehicle was gradually taken to ever higher speeds. During a test run on 8th of September, while travelling at roundabout 640 km/h (400 mph), one of the tail wheel fairings appeared to explode and the ensuing drag differences caused heavy oscillations that ended in a crash at 180 km/h (110 mph) with the vehicle rolling over and ripping the left rear wheel suspension apart.

The driver, LSA student and hobby rally driver Victor Barchenkov, miraculously left the vehicle almost unscathed, and the damage turned out to be only superficial. What had happened was an air pressure congestion inside of the wheel fairing, and the increasing revolutions of the wheels beyond 600 km/h caused small shock waves along the wheels, which eventually blew up the fairing, together with the tire. This accident stopped the 1988 trials, but not the work on the vehicle. Another disaster struck the LSA ChADI team when ChADI 9, which was still operated, crashed in 1988, too, and had to be written off completely.

 

In mid-1989 and with only a single high speed vehicle left, LSA team appeared again with „скорость“ at the shores of Lake Baskunchak – and this time the weather was more gracious and the track could be used from late June onwards. Analyzing last year’s accident and the gathered data, the vehicle had undergone repairs and some major modifications, including a new, anti-corrosive paintjob in light grey with red and white trim.

The most obvious change, though, was a completely re-shaped nose section: the original raked lower air intake lip had been considerably extended by almost 5 feet (the vehicle now had a total length of 49 ft 1 in/14,98 m) in order to enhance the downforce on the front wheels, and strakes along the lower nose ducted the airflow around the front wheels and towards the stabilizing fins. The central shock cone had been elongated and re-contoured, too, improving the airflow at high speeds.

New tireless all-aluminum wheels had been developed and mounted, because pressurized rubber tires, as formerly used, had turned out to be too unstable and unsafe. The central front wheels had received an additional aerodynamic fairing that prevented air ingestion into the lower fuselage, so that steering at high speeds became safer. The aerodynamic rear wheel fairings had by now been completely deleted and spoilers had been added to the rear suspension in order to keep the rear wheel on the ground at high speeds.

 

This time the goal was to push „скорость“ and the national land speed record in excess of 800 km/h (500 mph), and step by step the vehicle’s top speed was gradually increased. On August 15, an officially timed record attempt was made, again with Victor Barchenkov at the steering wheel. The first of the two obligatory runs within an hour was recorded at a very promising 846.961 km/h (526.277 mph), but, at the end of the second run, „скорость“ veered off and no time was measured. Even worse, the vehicle lost its parachute brakes and went out of control, skidding away from the dry race track into Lake Baskunchak’s wet salt sludge, where it hit a ground wave at around 200 mph (320 km/h) and was catapulted through the air into a brine pond where it landed on its right side and eventually sank. Again, pilot Victor Barchenkov remained mostly unharmed and was able to leave the car before it sank – but this fatal crash meant the end of the „скорость“ vehicle and the complete KhAGI 9-II project. Furthermore, the break-up of the Soviet Union at the same time prevented and further developments of high speed vehicles. The whereabouts of the „скорость“ wreck remain unclear, too, since no official attempt had been made to save the vehicle’s remains from Lake Baskunchak’s salt swamps.

  

The kit and its assembly:

This is another contribution to the late 2018 “Racing & Competition Group Build” at whatifmodelers.com. Since I primarily build aircraft in 1:72 scale, building a land speed record (LSR) vehicle from such a basis appeared like a natural choice. A slick streamliner? A rocket-powered prototype with Mach 1 potential? Hmmm… However, I wanted something else than the typical US or British Bonneville Salt Flats contender.

Inspiration struck when I remembered the real world high speed vehicle projects of LSA ChAGI in the former USSR, and especially the ill-fated, jet-powered ChADI 9, which looked a lot like Western, rocket-powered absolute LSR designs like The Blue Flame or Wingfoot Express 2. Another inspiration was a contemporary LSR vehicle called North American Eagle – basically a wingless F-104 Starfighter, put on wheels and sporting a garish, patriotic livery.

 

With this conceptual basis, the MiG-21 was quickly identified as the potential starting basis – but I wanted more than just a Fishbed sans wings and with some bigger wheels attached to it. I nevertheless wanted to retain the basic shape of the aircraft, but change the rest as good as possible with details that I have learned from reading about historic LSR vehicles (a very good source are the books by German author and LSR enthusiast Ferdinand C. W. Käsmann, which have, AFAIK, even been translated into English).

 

At the model’s core is a contemporary KP MiG-21MF, but it’s a hideous incarnation of the venerable Kovozávody Prostějov mold. While the wheels and the dashboard of this kit were surprisingly crisp, the fuselage halves did hardly match each other and some other parts like the landing gear covers could only be described as “blurred blobs”. Therefore it was no shame to slice the kit up, and the resulting kitbash with many donor parts and scratching almost became a necessity.

 

The MiG-21 fuselage and cockpit were more or less retained, the landing gear wells covered and PSR-ed. Fin, spine and the ventral stabilizer were cut away, and the attachment points for the wings and the horizontal stabilizers blended into the rest of the fuselage. Actually, only a few parts from the KP MiG-21 were eventually used.

 

The original shock cone in the air intake was used, but it was set further back into the nose opening – as an attachment point for a new, more organic shock cone which is actually the rear end of a drop tank from an Airfix 1:72 P-61 Black Widow. This detail was inspired by a real world benchmark: Art Arfons’ home-built “Green Monster” LSR car. This vehicle also inspired the highly modified air intake shape, which was scratched from the tail cone from a Matchbox 1:72 Blackburn Buccaneer – the diameter matched well with the MiG-21’s nose! With the new nose, I was able to retain the original MiG-21 layout, yet the shape and the extension forward changed the overall look enough to make it clear that this was not simply a MiG-21 on wheels.

 

With the spine gone, I also had to integrate a different, much smaller canopy, which came from an 1:144 Tornado. The cockpit opening had to be narrowed accordingly, and behind the canopy a new spine fairing was integrated – simply a piece from a streamlined 1:72 1.000 lb bomb plus lots of PSR.

Inside of the cockpit, a simpler seat was used, but the original cockpit tub and the dashboard were retained.

The large MiG-21 fin was replaced with a smaller piece, left over from an Amodel Kh-20 missile, with a scratched brake parachute fairing (cut from sprue material) placed under its rear. The exhaust nozzle was replaced, too, because the fit of the KP MiG-21’s rear end was abysmal. So I cut away a short piece and added an afterburner nozzle from a vintage 1:72 F-100, which fits well. Inside, the part’s rear wall was drilled open and extended inwards with a styrene tube.

 

The wheels of the vehicle come from an 1:72 Hasegawa “Panther with Schmalturm” tank kit – it comes not only with two turrets, but also with a second set of simplified track wheels. These had IMHO the perfect size and shape as massive aluminum wheels for the high speed vehicle.

For the front wheels, I used the thinner outer Panther wheels, and they were put, closely together, onto a central suspension pylon. This received a new “well” in the forward fuselage, with an internal attachment point. In order to streamline the front wheel installation (and also to change the overall look of the vehicle away from the MiG-21 basis), I added a scratched an aerodynamic fairing around it. This was made from tailored styrene strips, which were later filled and blended into the hull with putty.

 

The rear suspension was also fully scratched: the outriggers were made from styrene profiles while the wheel attachments were once part of an 1:35 tank kit suspension – I needed something to hold the three struts per side together. These parts look a bit large, but the vehicle is, after all, a Soviet design, so a little sturdiness may not be wrong, and I simply did not want to stick the wheels directly onto the outriggers. The rear wheels (in this case, the wider inner Panther track wheels with a central hub cover were used) also received a stabilizing notch around the contact surface, in an attempt to make them look slimmer than they actually are.

 

Final touches included the chines under the nose as well as spoilers on the rear suspension (both made from styrene profiles), and I added a pitot made from wire to the original MiG-21 angle of attack sensor fairing.

 

As an addition outside the model itself I also created a display base for the beauty pics, since I did not have anything at hand that would resemble the vastness of a flat and dry salt sea. The base is an 18x12” MDF board, on top of which I added a thin coat of white tile grout (which I normally use as a snow placebo, instead of plaster, which tends to absorb humidity over time and to become yellow). While the stuff was still wet I sprinkled some real salt onto the surface and wetted the whole affair with water sprays – hoping to create a flat yet structured surface with some glitter reflexes. And it actually worked!

  

Painting and markings:

I am not certain how ChADI 9 was painted (I assume overall silver), but I wanted for „скорость“ a little more color. Being a child of the Soviet era, red was a settled design element, but I thought that an all-red vehicle might have looked too cheesy. Other colors I considered were orange or white with blue trim, but did not find them to be appropriate for what I was looking. Eventually, I added some Russian Utilitarianism in the form of light grey for the upper hull (Humbrol 166, RAF Light Aircraft Grey), and the red (Humbrol 19) as a dark contrast around the complete air intake as well as the shock cone (somewhat inspired by the Green Monster #15 LSR vehicle), and then extended backwards into a narrowing cheatline along the flanks, which emphasizes the vehicle’s slender hull. For some more contrast between the two basic tones I later added thin white borders between them created with 2mm white decal stripes from TL Modellbau. Around the hull some bright red (Humbrol 238 Red Arrows Red) highlights as warning signs were added.

 

The vehicle’s afterburner section was painted with Modelmaster Steel Metallizer, the Panther wheels became Aluminum (Revell 99) with a black ink wash. Some black ink was also applied to the jet nozzle, so that the details became more pronounced, and some grinded graphite was used to enhance the burnt metal effect.

 

Since this would rather be an experimental car built and operated by a high school institute, and also operated in the Soviet Union, flashy sponsor markings would not be appropriate. Therefore I created some fictional marking at home with the help of PC software and printed them by myself. These designs included a fictional logo of the ChADI institute itself (created from a car silhouette drawing) and a logo for the vehicle’s title, “„скорость““. The latter was created from the cyrillic lettering, with some additions like the vehicle’s silhouette.

Unfortunately the production process for the home-made decals did not work properly – when coating the prints with gloss acrylic varnish the printer ink started to dissolve, bleeding magenta, so that the decals would look as if there was a red halo or glow around the otherwise black motifs. Thanks to the use of red in the vehicle’s overall design this flaw is not too apparent, so I stuck with the outcome and applied the decals to the car.

Beyond these basic markings, many stencils were added, including dull red inscriptions from an Italeri MiG-37 “Ferret” kit – finally, I found an expedient use for them! The Soviet flags on the fin came from an 1:144 Tu-144 airliner Braz Decal aftermarket sheet.

Finally, some panel lines were drawn onto the hull with a soft pencil and then the model was sealed with Italeri semi-gloss acrylic varnish. Just the black anti-glare panel in front of the windscreen became matt and the metallic rear section was left in “natural” finish.

  

I am very pleased with the outcome – the „скорость“ looks purposeful and does IMHO blend well into the line of spectacular USA and UK jet/rocket car designs that broke the 800 km/h barrier. I also find that, even though the MiG-21 ancestry is certainly there, the vehicle looks different enough so that the illusion that it was designed along the jet fighter’s lines (and not converted from one, like the real world “North American Eagle” which was built from an F-104 Starfighter) works well. I also think that the vehicle’s livery works well – it looks quite retro for a vehicle from the late Eighties, but that just adds to the “Soviet style”. An interesting project, outside of my normal comfort zone. :D

Some background:

The Soviet Laboratory of High-Speed Automobiles (LSA ChADI, today the Chardiv National Automobile and Highway University) was founded in 1953. One of the laboratory’s founders was Vladimir Nikitin, a famous racer not only inside the Soviet Union but also around the world. The main purpose of Vladimir Nikitin’s of was to build the fastest car in the world. This idea of creating race cars became the purpose of the laboratory and has been continued by students of Nikitin throughout the years, with research and prototypes in various fields of car propulsion.

 

The first car created in LSA by students was ChADI 2 in 1961. The body of the car was made of fiberglass, the first time that this material was used for a car body in the Soviet Union. This technology was improved and later used in mass-produced cars. Another famous LSA car was ChADI 7. To create it, Nikitin and his students used airplane wing elements as car body material and used the engine from a helicopter to power it. The highest speed of ChADI 7 – 400 kilometers per hour – was recorded on an airport runway near Chardiv in 1968, and it was at that time the fastest car in the Soviet Union, setting the national land speed record.

 

After this successful vehicle, Vladimir Nikitin started a new, even more ambitious project: a speed record car with the jet engine from a high performance airplane! The name of this project was ChADI 9, and it was ambitious. This time Nikitin and his team used a Tumansky RD-9 turbojet engine with a dry thrust of 25.5 kN (5,730 lbf), the same engine that powered the supersonic Mikoyan-Gurewich MiG-19 fighter plane. He expected that this needle-shaped car would be able to break the absolute land speed record, which meant supersonic speed at level zero of almost 1.200 kilometers an hour. The car was finished in 1981, but unfortunately ChADI 9 never participated in any race and no official top speed result was ever recorded. This had initially a very practical reason: in the 1980’s there were simply no tires in the USSR that could be safely used at the expected speeds in excess of 400 km/h, and there was furthermore no track long enough for a serious test drive in the Soviet Union! In consequence, ChADI 9 had to be tested on the runway of a military airport in the proximity of Chardiv, outfitted with wheels and tires from a MiG-19, but these were not ideal for prolonged high speeds. Film footage from these tests later appeared in a 1983 movie called “IgLa”.

The Automotive Federation of the United States even invited ChADI 9 to participate in an official record race in the USA, but this did not happen either, this time for political reasons. Nevertheless, the main contribution of this car was gathering experience with powerful jet engines and their operations in a ground vehicle, as well as experience with car systems that could withstand and operate at the expected high levels of speed, and the vehicle was frequently tested until it was destroyed in high speed tests in 1988 (see below).

 

ChADI 9 was not the end of Nikitin’s strife for speed (and the prestige associated with it). The know-how that the design team had gathered in the first years of testing ChADI 9 were subsequentially integrated into the LSA’s ultimate proposal not only to break the national, but also the absolute land speed record: with a new vehicle dubbed ChADI 9-II. This car was a completely new design, and its name was deliberately chosen in order to secure project budgets – it was easier to gain support for existing (and so far successful) projects rather than found new ones and convince superior powers of their value and success potential.

 

ChADI 9-II’s conceptual phase was launched in 1982 and it was basically a scaled-up evolution of ChADI 9, but it featured some significant differences. Instead of the RD-9 turbojet, the new vehicle was powered by a much more potent Tumansky R-25-300 afterburning turbojet with a dry thrust of 40.21 kN (9,040 lbf) and 69.62 kN (15,650 lbf) with full afterburner. This new engine (used and proven in the MiG-21 Mach 2 fighter) had already been thoroughly bench-tested by the Soviet Laboratory of High-Speed Automobiles in 1978, on an unmanned, tracked sled.

However, the development of ChADI 9-II and its details took more than two years of dedicated work by LSA ChADI’s students, and in 1984 the design was finally settled. The new vehicle was much bigger than its predecessor, 44 ft 10 in long, 15 ft 6¾ in wide, and 9 ft 10¾ in high (13.67 m by 4,75 m by 3,02 m), and it weighed around 9,000 lb (4 t). Its construction was based on a steel tube frame with an integrated security cell for the driver and an aluminum skin body, with some fibre glass elements. While ChADI 9’s slender cigar-shaped body with a circular diameter and the tricycle layout were basically retained, the front end of ChADI 9-II and its internal structure were totally different: instead of ChADI 9’s pointed nose, with the cockpit in the front and ahead of the vehicle’s front wheel and a pair of conformal (but not very efficient) side air intakes, ChADI 9-II featured a large, single orifice with a central shock cone. A small raked lower lip was to prevent FOD to the engine and act at the same time as a stabilizing front spoiler. The driver sat under a tight, streamlined canopy, the bifurcated air intake ducts internally flanking the narrow cockpit. Two steerable front wheels with a very narrow track were installed in front of the driver’s compartment. They were mounted side by side on a central steering pylon, which made them look like a single wheel. Behind the cockpit, still flanked by the air ducts, came two fuel tanks and finally, after a chamber where the air ducts met again, the engine compartment. Small horizontal stabilizers under the cockpit, which could be adjusted with the help of an electric actuator, helped keeping the vehicle’s nose section on the ground. Two small air brakes were mounted on the rear fuselage; these not only helped to reduce the vehicle’s speed, they could also be deployed in order to trim the aerodynamic downforce on the rear wheels. The latter ware carried on outriggers for a wide and stable track width and were covered in tight aerodynamic fairings, again made from fibre glass. The outriggers were furthermore swept back far enough so that the engine’s nozzle was placed in front of the rear wheel axis. This, together with a marked “nose-down” stance as well as a single swept fin on the rear above the afterburner nozzle with a brake parachute compartment, was to ensure stability and proper handling at expected speeds far in excess of 600 km/h (372 mph) without the use of the engine’s afterburner, and far more at full power.

 

Construction of ChADI 9-II lasted for more than another year, and in May 1986 the vehicle was rolled out and ready for initial trials at Chardiv, this time on the Chardiv State Aircraft Manufacturing Company’s runway. These non-public tests were successful and confirmed the soundness of the vehicle’s concept and layout. In the course of thorough tests until July 1987, ChADI 9-II was carefully pushed beyond the 400 km/h barrier and showed certain potential for more. This was the point when the vehicle was presented to the public (it could not be hidden due to the noisy trials within Chardiv’s city limits), and for this occasion (and marketing purposes) ChADI 9-II received a flashy livery in silver with red trim around the air intake and long the flanks and was officially christened with the more catchy title “„скорость“” (Skorost = Velocity).

 

Meanwhile, a potential area for serious high-speed trials had been identified with Lake Baskunchak, a salt sea near the Caspian Sea with flat banks that resembled the Bonneville Salt Flats in the USA. Lake Baskunchak became the site of further tests in 1988. Initially scheduled for May-July, the tests had to be postponed by six weeks due to heavy rain in the region, so that the sea would not build suitable dry salt banks for any safe driving tests. In late June the situation improved, and „скорость“ could finally take up its high speed tests.

 

During the following weeks the vehicle was gradually taken to ever higher speeds. During a test run on 8th of September, while travelling at roundabout 640 km/h (400 mph), one of the tail wheel fairings appeared to explode and the ensuing drag differences caused heavy oscillations that ended in a crash at 180 km/h (110 mph) with the vehicle rolling over and ripping the left rear wheel suspension apart.

The driver, LSA student and hobby rally driver Victor Barchenkov, miraculously left the vehicle almost unscathed, and the damage turned out to be only superficial. What had happened was an air pressure congestion inside of the wheel fairing, and the increasing revolutions of the wheels beyond 600 km/h caused small shock waves along the wheels, which eventually blew up the fairing, together with the tire. This accident stopped the 1988 trials, but not the work on the vehicle. Another disaster struck the LSA ChADI team when ChADI 9, which was still operated, crashed in 1988, too, and had to be written off completely.

 

In mid-1989 and with only a single high speed vehicle left, LSA team appeared again with „скорость“ at the shores of Lake Baskunchak – and this time the weather was more gracious and the track could be used from late June onwards. Analyzing last year’s accident and the gathered data, the vehicle had undergone repairs and some major modifications, including a new, anti-corrosive paintjob in light grey with red and white trim.

The most obvious change, though, was a completely re-shaped nose section: the original raked lower air intake lip had been considerably extended by almost 5 feet (the vehicle now had a total length of 49 ft 1 in/14,98 m) in order to enhance the downforce on the front wheels, and strakes along the lower nose ducted the airflow around the front wheels and towards the stabilizing fins. The central shock cone had been elongated and re-contoured, too, improving the airflow at high speeds.

New tireless all-aluminum wheels had been developed and mounted, because pressurized rubber tires, as formerly used, had turned out to be too unstable and unsafe. The central front wheels had received an additional aerodynamic fairing that prevented air ingestion into the lower fuselage, so that steering at high speeds became safer. The aerodynamic rear wheel fairings had by now been completely deleted and spoilers had been added to the rear suspension in order to keep the rear wheel on the ground at high speeds.

 

This time the goal was to push „скорость“ and the national land speed record in excess of 800 km/h (500 mph), and step by step the vehicle’s top speed was gradually increased. On August 15, an officially timed record attempt was made, again with Victor Barchenkov at the steering wheel. The first of the two obligatory runs within an hour was recorded at a very promising 846.961 km/h (526.277 mph), but, at the end of the second run, „скорость“ veered off and no time was measured. Even worse, the vehicle lost its parachute brakes and went out of control, skidding away from the dry race track into Lake Baskunchak’s wet salt sludge, where it hit a ground wave at around 200 mph (320 km/h) and was catapulted through the air into a brine pond where it landed on its right side and eventually sank. Again, pilot Victor Barchenkov remained mostly unharmed and was able to leave the car before it sank – but this fatal crash meant the end of the „скорость“ vehicle and the complete KhAGI 9-II project. Furthermore, the break-up of the Soviet Union at the same time prevented and further developments of high speed vehicles. The whereabouts of the „скорость“ wreck remain unclear, too, since no official attempt had been made to save the vehicle’s remains from Lake Baskunchak’s salt swamps.

  

The kit and its assembly:

This is another contribution to the late 2018 “Racing & Competition Group Build” at whatifmodelers.com. Since I primarily build aircraft in 1:72 scale, building a land speed record (LSR) vehicle from such a basis appeared like a natural choice. A slick streamliner? A rocket-powered prototype with Mach 1 potential? Hmmm… However, I wanted something else than the typical US or British Bonneville Salt Flats contender.

Inspiration struck when I remembered the real world high speed vehicle projects of LSA ChAGI in the former USSR, and especially the ill-fated, jet-powered ChADI 9, which looked a lot like Western, rocket-powered absolute LSR designs like The Blue Flame or Wingfoot Express 2. Another inspiration was a contemporary LSR vehicle called North American Eagle – basically a wingless F-104 Starfighter, put on wheels and sporting a garish, patriotic livery.

 

With this conceptual basis, the MiG-21 was quickly identified as the potential starting basis – but I wanted more than just a Fishbed sans wings and with some bigger wheels attached to it. I nevertheless wanted to retain the basic shape of the aircraft, but change the rest as good as possible with details that I have learned from reading about historic LSR vehicles (a very good source are the books by German author and LSR enthusiast Ferdinand C. W. Käsmann, which have, AFAIK, even been translated into English).

 

At the model’s core is a contemporary KP MiG-21MF, but it’s a hideous incarnation of the venerable Kovozávody Prostějov mold. While the wheels and the dashboard of this kit were surprisingly crisp, the fuselage halves did hardly match each other and some other parts like the landing gear covers could only be described as “blurred blobs”. Therefore it was no shame to slice the kit up, and the resulting kitbash with many donor parts and scratching almost became a necessity.

 

The MiG-21 fuselage and cockpit were more or less retained, the landing gear wells covered and PSR-ed. Fin, spine and the ventral stabilizer were cut away, and the attachment points for the wings and the horizontal stabilizers blended into the rest of the fuselage. Actually, only a few parts from the KP MiG-21 were eventually used.

 

The original shock cone in the air intake was used, but it was set further back into the nose opening – as an attachment point for a new, more organic shock cone which is actually the rear end of a drop tank from an Airfix 1:72 P-61 Black Widow. This detail was inspired by a real world benchmark: Art Arfons’ home-built “Green Monster” LSR car. This vehicle also inspired the highly modified air intake shape, which was scratched from the tail cone from a Matchbox 1:72 Blackburn Buccaneer – the diameter matched well with the MiG-21’s nose! With the new nose, I was able to retain the original MiG-21 layout, yet the shape and the extension forward changed the overall look enough to make it clear that this was not simply a MiG-21 on wheels.

 

With the spine gone, I also had to integrate a different, much smaller canopy, which came from an 1:144 Tornado. The cockpit opening had to be narrowed accordingly, and behind the canopy a new spine fairing was integrated – simply a piece from a streamlined 1:72 1.000 lb bomb plus lots of PSR.

Inside of the cockpit, a simpler seat was used, but the original cockpit tub and the dashboard were retained.

The large MiG-21 fin was replaced with a smaller piece, left over from an Amodel Kh-20 missile, with a scratched brake parachute fairing (cut from sprue material) placed under its rear. The exhaust nozzle was replaced, too, because the fit of the KP MiG-21’s rear end was abysmal. So I cut away a short piece and added an afterburner nozzle from a vintage 1:72 F-100, which fits well. Inside, the part’s rear wall was drilled open and extended inwards with a styrene tube.

 

The wheels of the vehicle come from an 1:72 Hasegawa “Panther with Schmalturm” tank kit – it comes not only with two turrets, but also with a second set of simplified track wheels. These had IMHO the perfect size and shape as massive aluminum wheels for the high speed vehicle.

For the front wheels, I used the thinner outer Panther wheels, and they were put, closely together, onto a central suspension pylon. This received a new “well” in the forward fuselage, with an internal attachment point. In order to streamline the front wheel installation (and also to change the overall look of the vehicle away from the MiG-21 basis), I added a scratched an aerodynamic fairing around it. This was made from tailored styrene strips, which were later filled and blended into the hull with putty.

 

The rear suspension was also fully scratched: the outriggers were made from styrene profiles while the wheel attachments were once part of an 1:35 tank kit suspension – I needed something to hold the three struts per side together. These parts look a bit large, but the vehicle is, after all, a Soviet design, so a little sturdiness may not be wrong, and I simply did not want to stick the wheels directly onto the outriggers. The rear wheels (in this case, the wider inner Panther track wheels with a central hub cover were used) also received a stabilizing notch around the contact surface, in an attempt to make them look slimmer than they actually are.

 

Final touches included the chines under the nose as well as spoilers on the rear suspension (both made from styrene profiles), and I added a pitot made from wire to the original MiG-21 angle of attack sensor fairing.

 

As an addition outside the model itself I also created a display base for the beauty pics, since I did not have anything at hand that would resemble the vastness of a flat and dry salt sea. The base is an 18x12” MDF board, on top of which I added a thin coat of white tile grout (which I normally use as a snow placebo, instead of plaster, which tends to absorb humidity over time and to become yellow). While the stuff was still wet I sprinkled some real salt onto the surface and wetted the whole affair with water sprays – hoping to create a flat yet structured surface with some glitter reflexes.

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

  

Some background:

The Yakovlev Yak-38 (Russian: Яковлева Як-38; NATO reporting name: "Forger") was the Soviet Naval Aviation's first and only operational VTOL strike fighter aircraft, in addition to being its first operational carrier-based fixed-wing aircraft. It was developed specifically for and served almost exclusively on the Kiev-class aircraft carriers.

 

Some specimen of the initial variant were tested during the Soviet Union's intervention in Afghanistan. These trials revealed several weaknesses of the construction in the form of unacceptable hot and high capabilities as well as a low payload. A further development for the Soviet Navy was therefore decided in August 1981, the abilities of which were fixed in October 1982. Already in November 1982 the first flight experiments of the prototype, leading to the Yak-38M, took place. In mid-1983 the manufacturing tests were completed and the production release was granted.

 

Anyway, the Soviet Air Force also had interest in a VTOL attack aircraft, which could provide CAS duties in immediate front line theatres, complementing the new Suchoj Su-25 Frogfoot and various attack helicopter types - but the Yak-38 was outright rejected. The Frontal Aviation demanded a much better performance, a dedicated avionics suite for ground attack duties and a higher payload of at least 2.500 kg (5.500 lb) in VTOL mode, plus an internal gun, and 3.000 kg (6.600 lb) when operating in C/STOL mode at sea level and from semi-prepared airstrips. For its primary ground attack role, the machine was also to be armored against projectiles of up to 0.5” around the lower hull and against 20mm rounds in the cockpit section. Finally, the machine had to be, compared with the Yak-38, simplified and be more rugged in order to ease frontline service and endure survivability.

 

OKB Yakovlev accepted the challenge and dusted off studies that had been undertaken during the Yak-38’s design stage. One of these was the Yak-38L (for 'lift/cruise'), a design built around a single, modified the AL-21F turbojet with vectoring nozzles and no lift engines, which were just dead weight in normal flight. This route seemed to be the most promising option for the Frontal Aviation's demands, even though it would mean a severe re-construction of the airframe.

 

The new aircraft, internally referred to as 'Izdeliye 138', was based on the Yak-38 airframe, but adapted and literally built around a lift/cruise variant of the large Kuznetsov NK-32 low bypass turbofan engine (originally, with an afterburner, powering the late Tu-144 airliners and the Tu-160 bomber). This engine’s initial derivative, NK-32L-1, adapted for operation with four vectoring nozzles, had a dry thrust of roundabout 110 kN (25,000 lbf) – about 10% more than the Yak-38’s engine trio all together. And the massive engine bore potential for at least 10% more power for the service aircraft.

 

The overall layout differed considerably from the long and sleek Yak-38: in order to create enough space for the large turbofan stage and its bigger, fixed-configuration air intakes, the fuselage had to be widened behind the cockpit section and the wings' main spar was moved upwards, so that the wings were now shoulder-mounted. The overall arrangement was reminiscent of the successful Hawker Harrier, but differed in some details like the landing gear, which was a classic tricycle design.

 

Cold air from the NK-32L’s initial turbofan stage was ducted into vectoring nozzles at the forward fuselage flanks, just in front of the aircraft's center of gravity, while the hot exhaust gasses passed through a bifurcated jet pipe through another pair of vectoring nozzles behind the CoG, in an arrangement which was also used in the Yak-38.

Slow speed control was ensured through puffer jet nozzles, fed by bleed air from the engine and placed on both wing tips as well as under the nose and in the aircraft’s tail section.

 

Teething troubles with the new engine, as well as the new, vectored nozzle arrangement, postponed the Izedeliye 138 prototype’s first flight until March 1986. Work was also slowed down because OKB Yakovlev had been working on the supersonic Yak-41 V/STOL fighter for the Soviet Navy, too. The Soviet Air Force's Frontal Aviation kept interested in the project, though, since they wanted a dedicated attack aircraft, and no complex multi-role fighter.

 

State acceptance trials lasted until mid 1987, and a total of four prototypes were built (including one for static ground tests). The Yak-138 was found to be easier to handle than the Yak-38, and the single engine made operations and also the handling during flight mode transition much easier and safer.

The prototypes were soon followed by a pre-production batch of 21 aircraft for field trials in frontline units. By then, the NK-32L had been much improved and now offered 137 kN (31,000 lbf) of thrust for short periods, which made it possible to meet all the Frontal Aviations requirements (esp. the call for 2.000 kg ordnance in VTOL mode).

 

Among its test pilots, the Yak-138 was quite popular and called "Balkon" ("Balcony") because of the good frontal view from the armored cockpit (offering a 17° downwards sight angle).

 

For frontline service, the aircraft was now equipped with sophisticated avionics, including a Sokol-138 navigation suite with a DISS-7 Doppler radar and a digital computer. A comprehensive ECM suite was installed for self-defence, including SPS-141 and SB-1 active jammers, KDS-23 chaff/flare dispensers built into the ventral pylon and an SPO-10 radar himing and warning system.

 

In accordance with the Yak-138‘s strike and low-level attack requirements, provisions were made to mount missiles and precision-guided munitions, as well as retaining a nuclear capability in line with other Soviet combat aircraft. An S-17VG-1 optical sight was fitted, as well as a laser rangefinder and marked-target seeker behind a flat, sloped window in the lower nose section.In the upper nose, between the aircraft's two characterisitic pitot booms, a Delta-2NG beam-riding missile guidance system antenna was placed in a small bullet fairing.

 

By 1989, the initial batch of aircraft had been delivered (receiving the NATO ASCC code 'Flitchbeam') and successfully tested. An order for 42 more aircraft had been placed and a dual training facility with the Soviet Navy at Kaspiysk AB in the Dagestan region (where Soviet Navy Yak-38U trainers were used for transitional training) established , when the disruption of the Soviet Union suddenly stopped the program in 1991 before the Yak-138 could enter production and service on a large scale.

 

Most of the machines in Frontal Aviation service fell to the Ukraine, where most of the machines had been based. This situation sealed the fate of the promising Yak-138 more or less over night: the now independent Ukraine did not want to keep the exotic type in its arsenal (together with some Yak-38s of the former Soviet Navy, too), and Russia did not want (and could simply not afford) to pay anything for the machines, which had been offered for an unknown sum.

 

Officially, all Ukrainian Yak-138 were scrapped until 1994, even though rumor has it that one or two airframes had been sold behind the scenes to China. In Russia only five specimen had survived, and since the spares situation was doubtful none could be kept in flying condition. One Yak-138 was eventually handed over to the Ulyanovsk Aircraft Museum, while the rest was either mothballed or scrapped, too. Unfortunately, the sole museum exhibit was lost in 1995 in a fire accident.

The kit and its assembly:

Sixth contribution to the “Soviet” Group Build at whatifmodelers.com in early 2017, on pretty short notice since the GB had been coming to its end. This totally fictional aircraft was inspired CG illustrations that had been roaming the WWW for some time: a hybrid between a Yak-38 (mostly the tail section), mated with an AV-8B Harrier II (cockpit, wings, landing gear). This did not look bad at all, yet a bit weird, with lift engines added in front of the fin. Certainly not conformal with a good CG balance – but I liked the idea of a single-engine Forger. And actually, OKB Yakovlev had been considering this.

 

So, the basic idea was a Harrier/Yak-38 kitbash. But the more I thought about the concept, the more additional donor parts came into play. One major addition was the nose section from a MiG-27 – with its slanted nose it would offer the pilot an excellent field of view, and the aircraft would, as a front line attack plane like the Harrier, not carry a radar, so the Flogger’s nose shape was perfect.

 

Therefore, initial ingredients for the Yak-138 were:

- Rear fuselage, wings and tail from a Tsukuda Hobby/Kangnam/Revell Yak-38

- Mid-fuselage with air intakes and front vectoring nozzles from a Matchbox Sea Harrier

- Cockpit from an Academy MiG-27

 

Work started with the MiG-27 cockpit, which was more or less taken OOB (except for side consoles in the cockpit and different seat), and the Yak-38 the tail section, built in parallel. To my surprise the Forger fuselage was easier to combine with the Harrier than expected, even though the position of the right cuts took multiple measurements until I came up with a proper solution. Since the Harrier is overall shorter than the Yak-38, the latter’s fuselage had to be shortened. I retained the tail cone, the Forger’s vectoring nozzles and the landing gear wells – and a 2cm plug was taken out between them. Instead of the Harrier’s tandem landing gear arrangement with outriggers under the outer wings, this one was to receive a conventional landing gear for optional C/STOL operations with a higher ordnance load, so that the Yak-38 parts were a welcome basis. Once the fuselage’s underside was more or less complete, the upper rest of the Yak-38 fuselage could be cut to size and integrated into the lower half and the Harrier parts.

 

After the rear end was settled, the MiG-27 cockpit could be mounted to the front end, which was slightly shortened by 2-3mm (since the Flogger’s is markedly longer than the short Harrier nose). In order to change the overall look of the aircraft, I eventually dropped the Harrier intakes and decided to use the Flogger’s boxy air intakes instead. These are considerably smaller than the gaping Harrier holes, and blending the conflicting shapes into each other for a more or less consistent look took several PSR turns. But it worked, better than expected, and it changes the aircraft’s look effectively, so that almost anything Harrier-esque was gone.

 

Once the fuselage was completed, I realized that I could not use the Yak-38 wings anymore. They are already pretty small, but with the more voluminous Harrier and Flogger parts added to the aircraft, they’d just be too small!

 

What to do...? I checked the donor bank and – in order to add even more individual flavor – used a pair of double delta wings from a PM Model Su-15! But only the core of them was left after considerable modifications: The inner delta wing sections were cut off, as well as the tip sections and parts of the trailing edge (for a planform similar to the Yak-38’s wings). On the underside, the landing gear openings were filled up and wing tips from the Yak-38, with puffer jet nozzles, transplanted. The inner leading edges had to be re-sculpted, too. The Su-15 wing fences were kept - a welcome, very Soviet design detail.

A lot of work, but I think it paid out because of the individual shape and look of these “new” wings?

 

As a consequence of the new, bigger wings, the little Yak-38 stabilizers could not be used anymore, either. In order to keep the square wing shape, I used modified stabilizers from an Intech F-16C/D – their trailing edges were clipped, but the bigger span retained. Together with the characteristic OOB Yak-38 fin they work well, and all of the aerodynamic surfaces IMHO blend well into the overall design of the aircraft.

 

After the hull was complete, work on smaller things could start. Under the fuselage, a GSh-23-2 pod from a MiG-21 was added, as well as pylons from the Tsukuda Yak-38 under the wings and a donor part from the scrap box in ventral position.

The landing gear is a mix, too: the main struts come from the Yak-38, the balloon wheels from the Matchbox Harrier. The front landing gear comes from the Academy MiG-27, including the wheels with mudguards. It was just mounted in a fashion that it now retracts forward.

 

The Harrier vectoring nozzles were modified, too, the exhaust “grills” replaced by square, simple ducts, scratched from styrene profile and putty. Care was taken that the nozzles would remain moveable in the fuselage flanks – for later hover pictures. The Yak-38’s nozzles were retained, but since they can OOB only be mounted in a single, fixed position, I added a simple pin to each nozzle, together with two holes in the hull, so that positions can now be switched between hover and level flight.

 

All around the hull, finally some small details like pitots, blade antennae and air scoops were finally added, and the ordnance consists of a pair of unguided 57mm rocket pods and a pair of Kh-23 (AS-7 Kerry) guided missiles – the latter come from the Yak-38 kit, but they are very crude and their tail sections were modified in order to come (slightly) closer to reality.

  

Painting and markings:

As an aircraft of the Soviet Frontal Aviation in the late Eighties, I settled upon a typical, disruptive four-tone camouflage with blue undersides. Very conventional, but with an exotic VTOL model I thought that a subtle look would be appropriate – and also separate it from the Naval Yak-38 cousin.

 

Design benchmark is the scheme on a contemporary MiG-21bis from a Soviert Frontal Aviation unit, chosen because of the disruptive pattern. The tones are guesstimates, though, based on various similar aircraft in more or less weathered condition. I settled for:

- Humbrol 195 (Dark Satin Green)

- Humbrol 78 (RAF Interior Green)

- Modelmaster 2005 (Burnt Umber)

- Humbrol 119 (Light Earth)

- Humbrol 115 (Russian Blue) for the undersides

 

The cockpit was painted in Russian Cockpit Green, opf course. The landing gear and their respective wells in a mix of Aluminum and Khaki Drab (Humbrol 56 & 26), and the wheel discs became bright green (Humbrol 131). Several di-electric panels and antennae were painted in Humbrol 106 (RAF Ocean Grey).

 

The kit received a thin black ink wash, in order to emphasize the panel lines, and panel post-shading with subtly lighter tones of the basic colors. National markings, codes and emblems come from several aftermarket sheets, mostly from High Decal Line and Begemot.

After some soot stains (grinded graphite) had been added, the kit was sealed with matt acrlyic varnish (Italeri) and the ordnace added.

  

Messy work, but I am surprised how consistent and normal the resulting aircraft appears? From certain angles, my Yak-138 creation reminds a good deal of the stillborn Hawker P.1154 (no similarity intended, though), the SEPECAT Jaguar or rather exotic Soko J-22 Orao/IAR-93 Vultur fighter bomber. IMHO, there’s also some A-4 Skyhawk style to it, esp. in planview? Anyway, there’s still some good Yak-38 heritage recognizable, and the tactical Frontal Aviation paint scheme suits the aircraft well - looks like a serious mud mover.

Some background:

The TIE/LN starfighter, or TIE/line starfighter, simply known as the TIE Fighter or T/F, was the standard Imperial starfighter seen in massive numbers throughout most of the Galactic Civil War and onward.

The TIE Fighter was manufactured by Sienar Fleet Systems and led to several upgraded TIE models such as TIE/sa bomber, TIE/IN interceptor, TIE/D Defender, TIE/D automated starfighter, and many more.

 

The original TIEs were designed to attack in large numbers, overwhelming the enemy craft. The Imperials used so many that they came to be considered symbols of the Empire and its might. They were also very cheap to produce, reflecting the Imperial philosophy of quantity over quality.

 

However, a disadvantage of the fighter was its lack of deflector shields. In combat, pilots had to rely on the TIE/LN's maneuverability to avoid damage. The cockpit did incorporate crash webbing, a repulsorlift antigravity field, and a high-g shock seat to help protect the pilot, however these did next to nothing to help protect against enemy blaster fire.

 

Due to the lack of life-support systems, each TIE pilot had a fully sealed flight suit superior to their Rebel counterparts. The absence of a hyperdrive also rendered the light fighter totally dependent on carrier ships when deployed in enemy systems. TIE/LNs also lacked landing gear, another mass-reducing measure. While the ships were structurally capable of "sitting" on their wings, they were not designed to land or disembark their pilots without special support. On Imperial ships, TIEs were launched from racks in the hangar bays.

 

The high success rate of more advanced Rebel starfighters against standard Imperial TIE Fighters resulted in a mounting cost of replacing destroyed fighters and their pilots. That, combined with the realization that the inclusion of a hyperdrive would allow the fleet to be more flexible, caused the Imperial Navy to rethink its doctrine of using swarms of cheap craft instead of fewer high-quality ones, leading to the introduction of the TIE Advanced x1 and its successor, the TIE Avenger. The following TIE/D Defender as well as the heavy TIE Escort Fighter (or TIE/E) were touted as the next "logical advance" of the TIE Series—representing a shift in starfighter design from previous, expendable TIE models towards fast, well armed and protected designs, capable of hyperspace travel and long-term crew teams which gained experience and capabilities over time.

 

The TIE/E Escort, was a high-performance TIE Series starfighter developed for the Imperial Navy by Sienar Fleet Systems and it was introduced into service shortly before the Battle of Endor. It was a much heavier counterpart to the agile and TIE/D fighter, and more of an attack ship or even a light bomber than a true dogfighter. Its role were independent long range operations, and in order to reduce the work load and boost morale a crew of two was introduced (a pilot and a dedicated weapon systems officer/WSO). The primary duty profile included attack and escort task, but also reconnoiter missions. The TIE/E shared the general layout with the contemporary TIE/D fighter, but the cockpit section as well as the central power unit were much bigger, and the ship was considerably heavier.

 

The crew enjoyed – compared with previous TIE fighter designs – a spacious and now fully pressurized cockpit, so that no pressurized suits had to be worn anymore. The crew members sat in tandem under a large, clear canopy. The pilot in front had a very good field of view, while the WSO sat behind him, in a higher, staggered position with only a limited field of view. Both work stations had separate entries, though, and places could not be switched in flight: the pilot mounted the cockpit through a hatch on port side, while the WSO entered the rear compartment through a roof hatch.

 

In a departure from the design of previous TIE models, instead of two parallel wings to either side of the pilot module, the TIE Escort had three quadanium steel solar array wings mounted symmetrically around an aft section, which contained an I-s4d solar ionization reactor to store and convert solar energy collected from the wing panels. The inclusion of a third wing provided additional solar power to increase the ship's range and the ship's energy management system was designed to allow weapons and shields to be charged with minimum loss of power to the propulsion system.

 

Although it was based on the standard twin ion engine design, the TIE/E’s propulsion system was upgraded to the entirely new, powerful P-sz9.8 triple ion engine. This allowed the TIE/E a maximum acceleration of 4,220 G or 21 MGLT/s and a top speed of 144 MGLT, or 1,680 km/h in an atmosphere — almost 40 percent faster than a former standard TIE Fighter. With tractor beam recharge power (see below) redirected to the engines, the top speed could be increased to 180 MGLT in a dash.

In addition to the main thrusters located in the aft section, the TIE Escort's triple wing design allowed for three arrays of maneuvering jets and it featured an advanced F-s5x flight avionics system to process the pilot's instructions. Production models received a class 2, ND9 hyperdrive motivator, modified from the version developed for the TIE Avenger. The TIE/E also carried a Sienar N-s6 Navcon navigation computer with a ten-jump memory.

 

Special equipment included a small tractor beam projector, originally developed for the TIE Avenger, which could be easily fitted to the voluminous TIE Escort. Models produced by Ysanne Isard's production facility regularly carried such tractor beams and the technology found other uses, such as towing other damaged starfighters until they could achieve the required velocity to enter hyperspace. The tractor beam had limited range and could only be used for a short time before stopping to recharge, but it added new tactics, too. For instance, the beam allowed the TIE/E crews to temporarily inhibit the mobility of enemy fighters, making it easier to target them with the ship's other weapon systems, or prevent enemies from clear shots.

 

The TIE Escort’s weapons systems were primarily designed to engage bigger ships and armored or shielded targets, like armed freighters frequently used by the Alliance. Thanks to its complex weapon and sensor suite, it could also engage multiple enemy fighters at once. The sensors also allowed an effective attack of ground targets, so that atmospheric bombing was a potential mission for the TIE/E, too.

.

The TIE Escort Fighter carried a formidable array of weaponry in two modular weapon bays that were mounted alongside the lower cabin. In standard configuration, the TIE/E had two L-s9.3 laser cannons and two NK-3 ion cannons. The laser and ion cannons could be set to fire separately or, if concentrated power was required, to fire-linked in either pairs or as a quartet.

The ship also featured two M-g-2 general-purpose warhead launchers, each of which could be equipped with a standard load of three proton torpedoes or four concussion missiles. Depending on the mission profile, the ship could be fitted with alternative warheads such as proton rockets, proton bombs, or magnetic pulse warheads.

Additionally, external stores could be carried under the fuselage, which included a conformal sensor pallet for reconnaissance missions or a cargo bay with a capacity for 500 kg (1.100 lb).

 

The ship's defenses were provided by a pair of forward and rear projecting Novaldex deflector shield generators—another advantage over former standard TIE models. The shields were designed to recharge more rapidly than in previous Imperial fighters and were nearly as powerful as those found on capital ships, so that the TIE/E could engage other ships head-on with a very high survivability. The fighters were not equipped with particle shields, though, relying on the reinforced titanium hull to absorb impacts from matter. Its hull and wings were among the strongest of any TIE series Starfighter yet.

 

The advanced starfighter attracted the attention of several other factions, and the Empire struggled to prevent the spread of the technology. The ship's high cost, together with political factors, kept it from achieving widespread use in the Empire, though, and units were assigned only to the most elite crews.

 

The TIE/E played a central role in the Empire's campaign against rogue Grand Admiral Demetrius Zaarin, and mixed Defender and Escort units participated in several other battles, including the Battle of Endor. The TIE Escort continued to see limited use by the Imperial Remnant up to at least 44 ABY, and was involved in numerous conflicts, including the Yuuzhan Vong War..

  

The kit and its assembly:

Another group build contribution, this time to the Science Fiction GB at whatifmodelers.com during summer 2017. Originally, this one started as an attempt to build a vintage MPC TIE Interceptor kit which I had bought and half-heartedly started to build probably 20 years ago. But I did not have the right mojo (probably, The Force was not strong enough…?), so the kit ended up in a dark corner and some parts were donated to other projects.

 

The sun collectors were still intact, though, and in the meantime I had the idea of reviving the kit’s remains, and convert it into (what I thought was) a fictional TIE Fighter variant with three solar panels. For this plan I got myself another TIE Interceptor kit, and stashed it away, too. Mojo was still missing, though.

 

Well, then came the SF GB and I took it as an occasion to finally tackle the build. But when I prepared for the build I found out that my intended design (over the years) more or less actually existed in the Star Wars universe: the TIE/D Defender! I could have built it with the parts and hand and some improvisation, but the design similarity bugged me. Well, instead of a poor copy of something that was more or less clearly defined, I rather decided to create something more individual, yet plausible, from the parts at hand.

 

The model was to stay a TIE design, though, in order to use as much donor material from the MPC kits as possible. Doing some legwork, I settled for a heavy fighter – bigger than the TIE Interceptor and the TIE/D fighter, a two-seater.

Working out the basic concept and layout took some time and evolved gradually. The creative spark for the TIE/E eventually came through a Revell “Obi Wan’s Jedi Starfighter” snap fit kit in my pile – actually a prize from a former GB participation at phoxim.de (Thanks a lot, Wolfgang!), and rather a toy than a true model kit.

 

The Jedi Fighter was in so far handy as it carries some TIE Fighter design traits, like the pilot capsule and the characteristic spider web windscreen. Anyway, it’s 1:32, much bigger than the TIE Interceptor’s roundabout 1:50 scale – but knowing that I’d never build the Jedi Starfighter OOB I used it as a donor bank, and from this starting point things started to evolve gradually.

 

Work started with the cockpit section, taken from the Jedi Starfighter kit. The two TIE Interceptor cockpit tubs were then mounted inside, staggered, and the gaps to the walls filled with putty. A pretty messy task, and once the shapes had been carved out some triangular tiles were added to the surfaces – a detail I found depicted in SW screenshots and some TIE Fighter models.

 

Another issue became the crew – even though I had two MPC TIE Interceptors and, theorectically, two pilot figures, only one of them could be found and the second crewman had to be improvised. I normally do not build 1:48 scale things, but I was lucky (and happy) to find an SF driver figure, left over from a small Dougram hoovercraft kit (from Takara, as a Revell “Robotech” reboxing). This driver is a tad bigger than the 1:50 TIE pilot, but I went with it because I did not want to invest money and time in alternatives. In order to justify the size difference I decided to paint the Dougram driver as a Chiss, based on the expanded SW universe (with blue skin and hair, and glowing red eyes). Not certain if this makes sense during the Battle of Endor timeframe, but it adds some color to the project – and the cockpit would not be visible in much detail since it would be finished fully closed.

 

Reason behind the closed canopy is basically the poor fit of the clear part. OOB, this is intended as an action toy – but also the canopy’s considerable size in 1:50 would prevent its original opening mechanism.

Additional braces on the rel. large window panels were created with self-adhesive tape and later painted over.

 

The rear fuselage section and the solar panel pylons were scratched. The reactor behind the cockpit section is actually a plastic adapter for water hoses, found in a local DIY market. It was slightly modified, attached to the cockpit “egg” and both parts blended with putty. The tail opening was closed with a hatch from the OOB TIE Interceptor – an incidental but perfect match in size and style.

 

The three pylons are also lucky finds: actually, these are SF wargaming/tabletop props and would normally be low walls or barriers, made from resin. For my build, they were more or less halved and trimmed. Tilted by 90°, they are attached to the hull with iron wire stabilizers, and later blended to the hull with putty, too.

 

Once the cockpit was done, things moved more swiftly. The surface of the hull was decorated with many small bits and pieces, including thin styrene sheet and profiles, steel and iron wire in various strengths, and there are even 1:72 tank tracks hidden somewhere, as well as protective caps from syringes (main guns and under the rear fuselage). It’s amazing how much stuff you can add to such a model – but IMHO it’s vital in order to create some structure and to emulate the (early) Star Wars look.

  

Painting and markings:

The less spectacular part of the project, even though still a lot of work because of the sheer size of the model’s surface. Since the whole thing is fictional, I tried to stay true to the Imperial designs from Episode IV-VI and gave the TIE/E a simple, all-light grey livery. All basic painting was done with rattle cans.

Work started with a basic coat of grey primer. On top of that, an initial coat of RAL 7036 Platingrau was added, esp. to the lower surfaces and recesses, for a rough shading effect. Then, the actual overall tone, RAL 7047, called “Telegrau 4”, one of Deutsche Telekom’s corporate tones, was added - mostly sprayed from abone and the sides onto the model. Fuselage and panels were painted separately, overall assembly was one of the final steps.

 

The solar panels were to stand out from the grey rest of the model, and I painted them with Revell Acrylic “Iron Metallic” (91) first, and later applied a rather rich wash with black ink , making sure the color settled well into the many small cells. The effect is pretty good, and the contrast was slightly enhanced through a dry-brushing treatment.

 

Only a few legible stencils were added all around the hull (most from the scrap box or from mecha sheets), the Galactic Empire Seal were inkjet-printed at home, as well as some tactical markings on the flanks, puzzled together from single digits in "Aurebash", one of the Imperial SW languages/fonts.

For some variety and color highlights, dozens of small, round and colorful markings were die-punched from silver, yellow, orange, red and blue decal sheet and were placed all over the hull - together with the large panels they blur into the the overall appearance, though. The hatches received thin red linings, also made from generic decals strips.

 

The cockpit interior was a bit challenging, though. Good TIE Fighter cockpit interior pictures are hard to find, but they suggest a dark grey tone. More confusingly, the MPC instructions call for a “Dark Green” cockpit? Well, I did not like the all-grey option, since the spaceship is already monochrome grey on the outside.

 

As a compromise I eventually used Tamiya XF-65 "Field Grey". The interior recieved a black ink in and dry-brushing treatment, and some instruments ansd screens were created with black decal material and glossy black paint; some neon paint was used for sci-fi-esque conmtraol lamps everywhere - I did not pay too much intention on the interior, since the cockpit would stay closed, and the thick clear material blurs everything inside.

Following this rationale, the crew was also painted in arather minimal fashion - both wear a dark grey uniform, only the Chiss pilot stands aout with his light blue skin and the flourescent red eyes.

 

After an overall black ink wash the model received a dry brusing treatment with FS 36492 and FS 36495, for a weathered and battle-worn look. After all, the "Vehement" would not survive the Ballte of Endor, but who knows what became of TIE/E "801"'s mixed crew...?

Finally, the kit was sealed with matt acrylic varnish, and some final cosmetic corrections made.

 

The display is a DIY creation, too, made from a 6x6" piece of wood, it's edges covered with edgebonder, a steel wire as holder, and finally the display was paited with semi-matt black acrylic paint from the rattle can.

  

A complex build, and the TIE/E more or less evolved along the way, with only the overall layout in mind. Work took a month, but I think it was worth the effort. This fantasy creation looks pretty plausible and blends well into the vast canonical TIE Fighter family - and I am happy that I finally could finish this mummy project, including the surplus Jedi Starfighter kit which now also find a very good use!

 

An epic one, and far outside my standard comfort zone. But a wothwhile build!

Production models received a class 2, ND9 hyperdrive motivator, modified from the version developed for the TIE Avenger. The TIE/E also carried a Sienar N-s6 Navcon navigation computer with a ten-jump memory.

 

Special equipment included a small tractor beam projector, originally developed for the TIE Avenger, which could be easily fitted to the voluminous TIE Escort. Models produced by Ysanne Isard's production facility regularly carried such tractor beams and the technology found other uses, such as towing other damaged starfighters until they could achieve the required velocity to enter hyperspace. The tractor beam had limited range and could only be used for a short time before stopping to recharge, but it added new tactics, too. For instance, the beam allowed the TIE/E crews to temporarily inhibit the mobility of enemy fighters, making it easier to target them with the ship's other weapon systems, or prevent enemies from clear shots.

 

The TIE Escort’s weapons systems were primarily designed to engage bigger ships and armored or shielded targets, like armed freighters frequently used by the Alliance. Thanks to its complex weapon and sensor suite, it could also engage multiple enemy fighters at once. The sensors also allowed an effective attack of ground targets, so that atmospheric bombing was a potential mission for the TIE/E, too.

.

The TIE Escort Fighter carried a formidable array of weaponry in two modular weapon bays that were mounted alongside the lower cabin. In standard configuration, the TIE/E had two L-s9.3 laser cannons and two NK-3 ion cannons. The laser and ion cannons could be set to fire separately or, if concentrated power was required, to fire-linked in either pairs or as a quartet.

The ship also featured two M-g-2 general-purpose warhead launchers, each of which could be equipped with a standard load of three proton torpedoes or four concussion missiles. Depending on the mission profile, the ship could be fitted with alternative warheads such as proton rockets, proton bombs, or magnetic pulse warheads.

Additionally, external stores could be carried under the fuselage, which included a conformal sensor pallet for reconnaissance missions or a cargo bay with a capacity for 500 kg (1.100 lb).

 

The ship's defenses were provided by a pair of forward and rear projecting Novaldex deflector shield generators—another advantage over former standard TIE models. The shields were designed to recharge more rapidly than in previous Imperial fighters and were nearly as powerful as those found on capital ships, so that the TIE/E could engage other ships head-on with a very high survivability. The fighters were not equipped with particle shields, though, relying on the reinforced titanium hull to absorb impacts from matter. Its hull and wings were among the strongest of any TIE series Starfighter yet.

 

The advanced starfighter attracted the attention of several other factions, and the Empire struggled to prevent the spread of the technology. The ship's high cost, together with political factors, kept it from achieving widespread use in the Empire, though, and units were assigned only to the most elite crews.

 

The TIE/E played a central role in the Empire's campaign against rogue Grand Admiral Demetrius Zaarin, and mixed Defender and Escort units participated in several other battles, including the Battle of Endor. The TIE Escort continued to see limited use by the Imperial Remnant up to at least 44 ABY, and was involved in numerous conflicts, including the Yuuzhan Vong War..

  

The kit and its assembly:

Another group build contribution, this time to the Science Fiction GB at whatifmodelers.com during summer 2017. Originally, this one started as an attempt to build a vintage MPC TIE Interceptor kit which I had bought and half-heartedly started to build probably 20 years ago. But I did not have the right mojo (probably, The Force was not strong enough…?), so the kit ended up in a dark corner and some parts were donated to other projects.

 

The sun collectors were still intact, though, and in the meantime I had the idea of reviving the kit’s remains, and convert it into (what I thought was) a fictional TIE Fighter variant with three solar panels. For this plan I got myself another TIE Interceptor kit, and stashed it away, too. Mojo was still missing, though.

 

Well, then came the SF GB and I took it as an occasion to finally tackle the build. But when I prepared for the build I found out that my intended design (over the years) more or less actually existed in the Star Wars universe: the TIE/D Defender! I could have built it with the parts and hand and some improvisation, but the design similarity bugged me. Well, instead of a poor copy of something that was more or less clearly defined, I rather decided to create something more individual, yet plausible, from the parts at hand.

 

The model was to stay a TIE design, though, in order to use as much donor material from the MPC kits as possible. Doing some legwork, I settled for a heavy fighter – bigger than the TIE Interceptor and the TIE/D fighter, a two-seater.

Working out the basic concept and layout took some time and evolved gradually. The creative spark for the TIE/E eventually came through a Revell “Obi Wan’s Jedi Starfighter” snap fit kit in my pile – actually a prize from a former GB participation at phoxim.de (Thanks a lot, Wolfgang!), and rather a toy than a true model kit.

 

The Jedi Fighter was in so far handy as it carries some TIE Fighter design traits, like the pilot capsule and the characteristic spider web windscreen. Anyway, it’s 1:32, much bigger than the TIE Interceptor’s roundabout 1:50 scale – but knowing that I’d never build the Jedi Starfighter OOB I used it as a donor bank, and from this starting point things started to evolve gradually.

 

Work started with the cockpit section, taken from the Jedi Starfighter kit. The two TIE Interceptor cockpit tubs were then mounted inside, staggered, and the gaps to the walls filled with putty. A pretty messy task, and once the shapes had been carved out some triangular tiles were added to the surfaces – a detail I found depicted in SW screenshots and some TIE Fighter models.

 

Another issue became the crew – even though I had two MPC TIE Interceptors and, theorectically, two pilot figures, only one of them could be found and the second crewman had to be improvised. I normally do not build 1:48 scale things, but I was lucky (and happy) to find an SF driver figure, left over from a small Dougram hoovercraft kit (from Takara, as a Revell “Robotech” reboxing). This driver is a tad bigger than the 1:50 TIE pilot, but I went with it because I did not want to invest money and time in alternatives. In order to justify the size difference I decided to paint the Dougram driver as a Chiss, based on the expanded SW universe (with blue skin and hair, and glowing red eyes). Not certain if this makes sense during the Battle of Endor timeframe, but it adds some color to the project – and the cockpit would not be visible in much detail since it would be finished fully closed.

 

Reason behind the closed canopy is basically the poor fit of the clear part. OOB, this is intended as an action toy – but also the canopy’s considerable size in 1:50 would prevent its original opening mechanism.

Additional braces on the rel. large window panels were created with self-adhesive tape and later painted over.

 

The rear fuselage section and the solar panel pylons were scratched. The reactor behind the cockpit section is actually a plastic adapter for water hoses, found in a local DIY market. It was slightly modified, attached to the cockpit “egg” and both parts blended with putty. The tail opening was closed with a hatch from the OOB TIE Interceptor – an incidental but perfect match in size and style.

 

The three pylons are also lucky finds: actually, these are SF wargaming/tabletop props and would normally be low walls or barriers, made from resin. For my build, they were more or less halved and trimmed. Tilted by 90°, they are attached to the hull with iron wire stabilizers, and later blended to the hull with putty, too.

 

Once the cockpit was done, things moved more swiftly. The surface of the hull was decorated with many small bits and pieces, including thin styrene sheet and profiles, steel and iron wire in various strengths, and there are even 1:72 tank tracks hidden somewhere, as well as protective caps from syringes (main guns and under the rear fuselage). It’s amazing how much stuff you can add to such a model – but IMHO it’s vital in order to create some structure and to emulate the (early) Star Wars look.

  

Painting and markings:

The less spectacular part of the project, even though still a lot of work because of the sheer size of the model’s surface. Since the whole thing is fictional, I tried to stay true to the Imperial designs from Episode IV-VI and gave the TIE/E a simple, all-light grey livery. All basic painting was done with rattle cans.

Work started with a basic coat of grey primer. On top of that, an initial coat of RAL 7036 Platingrau was added, esp. to the lower surfaces and recesses, for a rough shading effect. Then, the actual overall tone, RAL 7047, called “Telegrau 4”, one of Deutsche Telekom’s corporate tones, was added - mostly sprayed from abone and the sides onto the model. Fuselage and panels were painted separately, overall assembly was one of the final steps.

 

The solar panels were to stand out from the grey rest of the model, and I painted them with Revell Acrylic “Iron Metallic” (91) first, and later applied a rather rich wash with black ink , making sure the color settled well into the many small cells. The effect is pretty good, and the contrast was slightly enhanced through a dry-brushing treatment.

 

Only a few legible stencils were added all around the hull (most from the scrap box or from mecha sheets), the Galactic Empire Seal were inkjet-printed at home, as well as some tactical markings on the flanks, puzzled together from single digits in "Aurebash", one of the Imperial SW languages/fonts.

For some variety and color highlights, dozens of small, round and colorful markings were die-punched from silver, yellow, orange, red and blue decal sheet and were placed all over the hull - together with the large panels they blur into the the overall appearance, though. The hatches received thin red linings, also made from generic decals strips.

 

The cockpit interior was a bit challenging, though. Good TIE Fighter cockpit interior pictures are hard to find, but they suggest a dark grey tone. More confusingly, the MPC instructions call for a “Dark Green” cockpit? Well, I did not like the all-grey option, since the spaceship is already monochrome grey on the outside.

 

As a compromise I eventually used Tamiya XF-65 "Field Grey". The interior recieved a black ink in and dry-brushing treatment, and some instruments ansd screens were created with black decal material and glossy black paint; some neon paint was used for sci-fi-esque conmtraol lamps everywhere - I did not pay too much intention on the interior, since the cockpit would stay closed, and the thick clear material blurs everything inside.

Following this rationale, the crew was also painted in arather minimal fashion - both wear a dark grey uniform, only the Chiss pilot stands aout with his light blue skin and the flourescent red eyes.

 

After an overall black ink wash the model received a dry brusing treatment with FS 36492 and FS 36495, for a weathered and battle-worn look. After all, the "Vehement" would not survive the Ballte of Endor, but who knows what became of TIE/E "801"'s mixed crew...?

Finally, the kit was sealed with matt acrylic varnish, and some final cosmetic corrections made.

 

The display is a DIY creation, too, made from a 6x6" piece of wood, it's edges covered with edgebonder, a steel wire as holder, and finally the display was paited with semi-matt black acrylic paint from the rattle can.

  

A complex build, and the TIE/E more or less evolved along the way, with only the overall layout in mind. Work took a month, but I think it was worth the effort. This fantasy creation looks pretty plausible and blends well into the vast canonical TIE Fighter family - and I am happy that I finally could finish this mummy project, including the surplus Jedi Starfighter kit which now also find a very good use!

 

An epic one, and far outside my standard comfort zone. But a wothwhile build!

Some background

The Focke Wulf Ta 338 originated as a response of request by the RLM in mid 1943 for an aircraft capable of vertical takeoff and landing (VTOL), optimized for the interceptor and point defense role and without a hazardous liquid rocket engine as means of propulsion. In the course of the year, several German manufacturers responded with a multitude of highly innovative if not unusual design, including Heinkel with the ducted fan project "Lerche", Rheinmetall-Borsig with a jet-powered tailsitter, and Focke Wulf. This company’s engineering teams submitted two designs: the revolutionary "Triebflügel" concept and the more conservative, yet still futuristic "P.03.10338" tail sitter proposal, conceived by Focke Wulf’s leading engineer Kurt Tank and Walter Kappus from BMW, responsible for the engine development.

 

The P.03.10338 was based on the proven Fw 190 fighter, but the similarities were only superficial. Only the wings and a part of the fuselage structure around the cockpit would be used, but Tank assumed that using existing parts and tools would appreciably reduce development and production time.

A great part of the fuselage structure had to be re-designed to accommodate a powerful BMW 803 engine and its integral gearbox for an eight-bladed contraprop.

 

The BMW 803 was BMW's attempt to build a high-output aircraft engine, primarily for heavy bombers, by basically "coupling" two BMW 801 engines back-to-back into a single and very compact power unit. The result was a 28-cylinder, four-row radial engine, each comprising a multiple-bank in-line engine with two cylinders in each bank, which, due to cooling concerns, were liquid cooled.

 

This arrangement was from the start intended to drive independent contra-rotating propellers, in order to avoid stiffness problems with the whole engine driving just a single crankshaft and also to simply convert the raw power of this unit into propulsion. The front half of the engine drove the front propeller directly, while the rear engine drove a number of smaller shafts that passed between the cylinders of the front engine before being geared back together to drive the rear prop. This complex layout resulted in a rather large and heavy gearbox on the front of the engine, and the front engine needing an extended shaft to "clear" that gearbox. The four-row 803 engine weighed 2,950 kg (6,490 lb) dry and 4,130 kg (9,086 lb) fully loaded, and initial versions delivered 3,900 PS (3,847 hp; 2,868 kW).

 

While the engine was heavy and there were alternatives with a better weight/output ratio (e. g. the Jumo 222), the BMW 803 was favored for this project because it was the most powerful engine available, and it was relatively compact so that it could be fitted into a fighter's airframe. On the P.03.10338 it drove an all-metal, eight-blade contraprop with a diameter of 4,25 m (13 ft 11 in).

 

In order to accept this massive engine, the P.03.10338’s structure had to be stiffened and the load-bearing structures re-arranged. The aircraft kept the Fw 190's wing structure and surface, but the attachment points at the fuselage had to be moved for the new engine mount, so that they ended up in mid position. The original space for the Fw 190's landing gear was used for a pair of radiator baths in the wings' inner leading edge, the port radiator catering to the front engine half while the radiator on starboard was connected with the rear half. An additional annular oil and sodium cooler for the gearbox and the valve train, respectively, was mounted in the fuselage nose.

 

The tail section was completely re-designed. Instead of the Fw 190's standard tail with fin and stabilizers the P.03.10338’s tail surfaces were a reflected cruciform v-tail (forming an x) that extended above and below the fuselage. On the four fin tips, aerodynamic bodies carried landing pads while the fuselage end contained an extendable landing damper. The pilot sat in a standard Fw 190 cockpit, and the aircraft was supposed to start and land vertically from a mobile launch pad. In the case of an emergency landing, the lower stabilizers could be jettisoned. Nor internal armament was carried, instead any weaponry was to be mounted under the outer wings or the fuselage, in the form of various “Rüstsätze” packages.

 

Among the many exotic proposals to the VTOL fighter request, Kurt Tank's design appeared as one of the most simple options, and the type received the official RLM designation Ta 338. In a rush of urgency (and maybe blinded by clever Wunderwaffen marketing from Focke Wulf’s side), a series of pre-production aircraft was ordered instead of a dedicated prototype, which was to equip an Erprobungskommando (test unit, abbreviated “EK”) that would evaluate the type and develop tactics and procedures for the new fighter.

 

Fueled by a growing number of bomber raids over Germany, the “EK338” was formed as a part of JG300 in August 1944 in Schönwalde near Berlin, but it took until November 1944 that the first Ta 338 A-0 machines were delivered and made operational. These initial eight machines immediately revealed several flaws and operational problems, even though the VTOL concept basically worked and the aircraft flew well – once it was in the air and cruising at speeds exceeding 300 km/h (186 mph).

 

Beyond the many difficulties concerning the aircraft’s handling (esp. the landing was hazardous), the lack of a landing gear hampered ground mobility and servicing. Output of the BMW 803 was sufficient, even though the aircraft had clear limits concerning the take-off weight, so that ordnance was limited to only 500 kg (1.100 lb). Furthermore, the noise and the dust kicked up by starting or landing aircraft was immense, and servicing the engine or the weapons was more complicated than expected through the high position of many vital and frequently tended parts.

 

After three Ta 338 A-0 were lost in accidents until December 1944, a modified version was ordered for a second group of the EK 338. This led to the Ta 338 A-1, which now had shorter but more sharply swept tail fins that carried single wheels and an improved suspension under enlarged aerodynamic bodies.

This machine was now driven by an improved BMW 803 A-2 that delivered more power and was, with an MW-50 injection system, able to produce a temporary emergency output of 4.500 hp (3.308 kW).

 

Vertical start was further assisted by optional RATO units, mounted in racks at the rear fuselage flanks: either four Schmidding SG 34 solid fuel booster rockets, 4.9 kN (1,100 lbf) thrust each, or two larger 9.8 kN (2,203 lbf) solid fuel booster rockets, could be used. These improvements now allowed a wider range of weapons and equipment to be mounted, including underwing pods with unguided rockets against bomber pulks and also a conformal pod with two cameras for tactical reconnaissance.

 

The hazardous handling and the complicated maintenance remained the Ta 338’s Achilles heel, and the tactical benefit of VTOL operations could not outbalance these flaws. Furthermore, the Ta 338’s range remained very limited, as well as the potential firepower. Four 20mm or two 30mm cannons were deemed unsatisfactory for an interceptor of this class and power. And while bundles of unguided missiles proved to be very effective against large groups of bombers, it was more efficient to bring these weapons with simple and cheap vehicles like the Bachem Ba 349 Natter VTOL rocket fighter into target range, since these were effectively “one-shot” weapons. Once the Ta 338 fired its weapons it had to retreat unarmed.

 

In mid 1945, in the advent of defeat, further tests of the Ta 338 were stopped. I./EK338 was disbanded in March 1945 and all machines retreated from the Eastern front, while II./EK338 kept defending the Ruhrgebiet industrial complex until the Allied invasion in April 1945. Being circled by Allied forces, it was not possible to evacuate or destroy all remaining Ta 338s, so that at least two more or less intact airframes were captured by the U.S. Army and later brought to the United States for further studies.

The kit and its assembly:

This purely fictional kitbashing is a hardware tribute to a highly inspiring line drawing of a Fw 190 VTOL tailsitter – actually an idea for an operational RC model! I found the idea, that reminded a lot of the Lockheed XFV-1 ‘Salmon’ prototype, just with Fw 190 components and some adaptations, very sexy, and so I decided on short notice to follow the urge and build a 1:72 version of the so far unnamed concept.

 

What looks simple (“Heh, it’s just a Fw 190 with a different tail, isn’t it?”) turned out to become a major kitbashing. The basis was a simple Hobby Boss Fw 190 D-9, chose because of the longer tail section, and the engine would be changed, anyway. Lots of work followed, though.

 

The wings were sliced off and moved upwards on the flanks. The original tail was cut off, and the cruciform fins are two pairs of MiG-21F stabilizers (from an Academy and Hasegawa kit), outfitted with reversed Mk. 84 bombs as aerodynamic fairings that carry four small wheels (from an 1:144 T-22M bomber) on scratched struts (made from wire).

 

The cockpit was taken OOB, only a pilot figure was cramped into the seat in order to conceal the poor interior detail. The engine is a bash from a Ju 188’s BMW 801 cowling and the original Fw 190 D-9’s annular radiator as well as a part of its Jumo 213 cowling. BMW 801 exhaust stubs were inserted, too, and the propeller comes from a 1:100 VEB Plasticart Tu-20/95 bomber.

 

Since the BMW 803 had liquid cooling, radiators had to go somewhere. The annular radiator would certainly not have been enough, so I used the space in the wings that became available through the deleted Fw 190 landing gear (the wells were closed) for additional radiators in the wings’ leading edges. Again, these were scratched with styrene profiles, putty and some very fine styrene mesh.

 

As ordnance I settled for a pair of gun pods – in this case these are slipper tanks from a Hobby Boss MiG-15, blended into the wings and outfitted with hollow steel needles as barrels.

  

Painting and markings:

Several design options were possible: all NMF with some colorful markings or an overall RLM76 finish with added camouflage. But I definitively went for a semi-finished look, inspired by late WWII Fw 190 fighters.

 

For instance, the wings’ undersides were partly left in bare metal, but the rudders painted in RLM76 while the leading edges became RLM75. This color was also taken on the wings’ upper sides, with RLM82 thinly painted over. The fuselage is standard RLM76, with RLM82 and 83 on the upper side and speckles on the flanks. The engine cowling became NMF, but with a flashy ‘Hartmann Tulpe’ decoration.

 

Further highlights are the red fuselage band (from JG300 in early 1945) and the propeller spinner, which received a red tip and segments in black and white on both moving propeller parts. Large red “X”s were used as individual aircraft code – an unusual Luftwaffe practice but taken over from some Me 262s.

 

After a light black ink wash some panel shading and light weathering (e.g. exhaust soot, leaked oil, leading edges) was done, and the kit sealed under matt acrylic varnish.

  

Building this “thing” on the basis of a line drawing was real fun, even though challenging and more work than expected. I tried to stay close to the drawing, the biggest difference is the tail – the MiG-21 stabilizers were the best option (and what I had at hand as donation parts), maybe four fins from a Hawker Harrier or an LTV A-7 had been “better”, but now the aircraft looks even faster. ;)

Besides, the Ta 338 is so utterly Luft ’46 – I am curious how many people might take this for real or as a Hydra prop from a contemporary Captain America movie…

I hope I got that translation right: "Armored slug with antenna trailer". Taking the Mak Nutcracker and blending it with a Nudibranch.

Some background:

The Sondergerät SG104 "Münchhausen" was a German airborne recoillless 355.6 mm (14-inch) caliber gun, intended to engage even the roughest enemy battleships, primarily those of the Royal Navy. The design of this unusual and massive weapon began in 1939. The rationale behind it was that a battleship’s most vulnerable part was the deck – a flat surface, with relatively thin armor (as typical hits were expected on the flanks) and ideally with vital targets underneath, so that a single, good hit would cripple of even destroy a ship. The purpose of such a high angle of attack was likely to allow the projectile to penetrate the target ship's deck, where the ship's armor, if there was any, would have been much thinner than the armor on its sidesHowever, hitting the deck properly with another ship’s main gun was not easy, since it could only be affected through indirect hits and the typical angle of the attack from aballistic shot would not necessarily be ideal for deep penetration, esp. at long range.

The solution to this problem: ensure that the heavy projectile would hit its target directly from above, ideally at a very steep angle. To achieve this, the gun with battleship caliber was “relocated” from a carrier ship or a coastal battery onto an aircraft – specifically to a type that was capable of dive-bombing, a feature that almost any German bomber model of the time offered.

 

Firing such a heavy weapon caused a lot fo problems, which were severe even if the gun was mounted on a ship or on land. To compensate for such a large-caliber gun’s recoil and to make firing a 14 in shell (which alone weighed around almost 700 kg/1.550 lb, plus the charge) from a relatively light airframe feasible, the respective gun had to be as light as possible and avoid any recoil, which would easily tear an aircraft – even a bomber – apart upon firing. Therefore, the Gerät 104 was designed as a recoilless cannon. Its firing system involved venting the same amount of the weapon's propellant gas for its round to the rear of the launch tube (which was open at both ends), in the same fashion as a rocket launcher. This created a forward directed momentum which was nearly equal to the rearward momentum (recoil) imparted to the system by accelerating the projectile itself. The balance thus created did not leave much net momentum to be imparted to the weapon's mounting or the carrying airframe in the form of felt recoil. A further share of the recoil induced by the moving round itself could be compensated by a muzzle brake which re-directed a part of the firing gases backwards. Since recoil had been mostly negated, a heavy and complex recoil damping mechanism was not necessary – even though the weapon itself was huge and heavy.

 

Work on the "Münchhausen" device (a secret project handle after a fictional German nobleman created by the German writer Rudolf Erich Raspe in the late 18th century who reputedly had ridden on a cannonball between enemy frontlines), was done by Rheinmetall-Borsig and lasted until 1941. The first test of a prototype weapon was conducted on 9th of September 1940 in Unterlüss with a satisfactory result, even though the weapon was only mounted onto an open rack and not integrated into an airframe yet. At that time, potential carriers were the Ju 88, the Dornier Do 217 and the new Junkers Ju 288. Even though the system’s efficacy was doubted, the prospect of delivering a single, fatal blow to an important , armored arget superseded any doubts at the RLM, and the project was greenlit in early 1942 for the next stage: the integration of the Sondergerät 104 into an existing airframe. The Ju 88 and its successor, the Ju 188, turned out to be too light and lacked carrying capacity for the complete, loaded weapon, and the favored Ju 288 was never produced, so that only the Dornier Do 217 or the bigger He 177 remained as a suitable carriers. The Do 217 was eventually chosen because it had the biggest payload and the airframe was proven and readily available.

 

After calculations had verified that the designed 14 in rifle would have effectively no recoil, preliminary tests with dumm airframes were carried out. After ground trials with a Do 217 E day bomber to check recoil and blast effects on the airframe, the development and production of a limited Nullserie (pre-production series) of the dedicated Do 217 F variant for field tests and eventual operational use against British sea and land targets was ordered in April 1942.

 

The resulting Do 217 F-0 was based on the late “E” bomber variant and powered by a pair of BMW 801 radial engines. It was, however, heavily modified for its unique weapon and the highly specialized mission profile: upon arriving at the zone of operation at high altitude, the aircraft would initiate a dive with an angle of attack between 50° and 80° from the horizontal, firing the SG 104 at an altitude between 6,000 and 2,000 meters. The flight time of the projectile could range from 16.0 seconds for a shot from an altitude of 6,000 meters at a 50° angle to just 4.4 seconds for a shot from 2.000 meters at an almost vertical 80° angle. Muzzle velocity of the SG 104 was only 300 m/s, but, prior to impact, the effective velocity of the projectile was projected to range between 449 and 468 m/s (1,616 to 1,674 km/h). Together with the round's weight of roughly 700 kg (1.550 lb) and a hardened tip, this would still ensure a high penetration potential.

 

The operational Sondergerät 104 had an empty mass of 2.780 kg (6,123 lb) and its complete 14 inch double cartridge weighed around 1.600 kg (3,525 lb). The loaded mass of the weapon was 4,237 kg, stretching the limits of the Do 217’s load capacity to the maximum, so that some armor and less vital pieces of equipment were deleted. Crew and defensive armament were reduced to a minimum.

Even though there had been plans to integrate the wepaon into the airframe (on the Ju 288), the Gerät 104 was on the Do 217 F-0 mounted externally and occupied the whole space under the aircraft, precluding any use of the bomb bay. The latter was occupied by the Gerät 104’s complex mount, which extended to the outside under a streamlined fairing and held the weapon at a distance from the airframe. Between the mount’s struts inside of the fuselage, an additional fuel tank for balance reasons was added, too.

The gun’s center, where the heavy round was carried, was positioned under the aircraft’s center of gravity, so that the gun barrel markedly protruded from under the aircraft’s nose. To make enough space, the Do 217 Es bomb aimer’s ventral gondola and his rearward-facing defensive position under the cockpit were omitted and faired over. The nose section was also totally different: the original extensive glazing (the so-called “Kampfkopf”) was replaced by a smaller, conventional canopy, similar to the later Do 217 J and N night fighter versions, together with a solid nose - the original glass panels would have easily shattered upon firing the gun, esp. in a steep high-speed dive. A "Lotfernrohr" bomb aiming device was still installed in a streamlined and protected fairing, though, so that the navigator could guide the pilot during the approach to the target and during the attack run.

To stabilize the heavy aircraft during its attack and to time- and safely pull out of the dive, a massive mechanical dive brake was mounted at the extended tail tip, which unfolded with four "petals". A charecteristic stabilizing dorsal strake was added between the twin fins, too.

 

The ventral area behind the gun’s rear-facing muzzle received additional metal plating and blast guiding vanes, after trials in late 1940 had revealed that firing the SG 104 could easily damage the Do 217’s tail structure, esp. all of the tail surfaces’ rudders and the fins’ lower ends in particular. Due to all this extra weight, the Do 217 F-0’s defensive armament consisted only of a single 13 mm MG 131 machine gun in a manually operated dorsal position behind the cockpit cabin, which offered space for a crew of three. A fixed 15 mm MG 151 autocannon was mounted in the nose, too, a weapon with a long barrel for extended range and accuracy. It was not an offensive weapon, though, rather intended as an aiming aid for the SG 104 because it was loaded with tracer bullets: during the final phase of the attack dive, the pilot kept firing the MG 151, and the bullet trail showed if he was on target to fire the SG 104 when the right altitude/range had been reached.

 

The first Do 217 F-0 was flown and tested in late 1943, and after some detail changes the type was cleared for a limited production run of ten aircraft in January 1944. The first operational machine was delivered to a dedicated testing commando, the Erprobungskommando 104 “Münchhausen”, also known as “Sonderkommando Münchhausen” or simply “E-Staffel 104”. The unit was based at Bordeaux/Merignac and directly attached to the KG 40's as a staff flight. At that time, KG 40 operated Do 217 and He 177 bombers and frequently flew reconnaissance and anti-shipping missions over the Atlantic west of France, up to the British west and southern coast, equipped with experimental Henschel Hs 293 glide bombs.

 

Initial flights confirmed that the Do 217 airframe was burdened with the SG 104 to its limits, the already rather sluggish aircraft (the Do 217 had generally a high wing loading and was not easy to fly) lost anything that was left of what could be called agility. It needed an experienced pilot to handle it safely, esp. during start and landing. It is no wonder that two Do 217 F-0s suffered ground accidents during the first two weeks of operations, but the machines could be repaired, resume the test program and carry out attack missions.

However, during one of the first test shots with the weapon, one Do 217 F-0 lost its complete tail section though the gun blast, and the aircraft crashed into the Bay of Biscay, killing the complete crew.

 

On 4th or April 1944 the first "hot" attack against an enemy ship was executed in the Celtic Sea off of Brest, against a convoy of 20 ships homeward bound from Gibraltar. The attack was not successful, though, the shot missing its target, and the German bomber was attacked and heavily damaged by British Bristol Beaufighters that had been deployed to protect the ships. The Do 217F-0 eventually crashed and sank into the Atlantic before it could reach land again.

 

A couple of days later, on 10th of April, the first attempt to attack and destroy a land target was undertaken: two Do 217 F-0s took off to attack Bouldnor Battery, an armored British artillery position located on the Isle of Wight. One machine had to abort the attack due to oil leakages, the second Do 217 F-0 eventually reached its target and made a shallow attack run, but heavy fog obscured the location and the otherwise successful shot missed the fortification. Upon return to its home base the aircraft was intercepted by RAF fighters over the Channel and heavily damaged, even though German fighters deployed from France came to the rescue, fought the British attackers off and escorted the limping Do 217 F-0 back to its home base.

 

These events revealed that the overall SG 104 concept was generally feasible, but also showed that the Do 217 F-0 was very vulnerable without air superiority or a suitable escort, so that new tactics had to be developed. One consequence was that further Do 217 F-0 deployments were now supported by V/KG 40, the Luftwaffe's only long range maritime fighter unit. These escorts consisted of Junkers Ju 88C-6s, which were capable of keeping up with the Do 217 F-0 and fend of intercepting RAF Coastal Command’s Beaufighters and later also Mosquitos.

 

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

 

These tests did not last long, though. During the Allied Normandy landings in June 1944 E-Staffel 104 was hastily thrown into action and made several poorly-prepared attack runs against Allied support ships. The biggest success was a full hit and the resulting sinking of the Norwegian destroyer HNoMS Svenner (G03) by "1A+BA" at dawn on 6th of June, off Sword, one of the Allied landing zones. Other targets were engaged, too, but only with little effect. This involvement, however, led to the loss of three Do 217 F-0s within just two days and four more heavily damaged aircraft – leaving only two of EKdo 104's Do 217 F-0s operational.

 

With the Allied invasion of France and a worsening war condition, the SG 104 program was stopped in August 1944 and the idea of an airborne anti-ship gun axed in favor of more flexible guided weapons like the Hs 293 missile and the Fritz-X glide bomb. Plans for a further developed weapon with a three-round drum magazine were immediately stopped, also because there was no carrier aircraft in sight that could carry and deploy this complex 6.5 tons weapon. However, work on the SG 104 and the experience gained from EKdo 104's field tests were not in vain. The knowledge gathered from the Münchhausen program was directly used for the design of a wide range of other, smaller recoilless aircraft weapons, including the magnetically-triggered SG 113 "Förstersonde" anti-tank weapon or the lightweight SG 118 "Rohrblock" unguided air-to-air missile battery for the Heinkel He 162 "Volksjäger".

The kit and its assembly:

This was another submission to the "Gunships" group build at whatifmodellers.com in late 2021, and inspiration struck when I realized that I had two Italeri Do 217 in The Stash - a bomber and a night fighter - that could be combined into a suitable (fictional) carrier for a Sondergerät 104. This mighty weapon actually existed and even reached the hardware/test stage - but it was never integrated into an airframe and tested in flight. But that's what this model is supposed to depict.

 

On the Do 217, the Sg 104 would have been carried externally under the fuselage, even though there had been plans to integrate this recoilless rifle into airframes, esp. into the Ju 288. Since the latter never made it into production, the Do 217 would have been the most logical alternative, also because it had the highest payload of all German bombers during WWII and probably the only aircraft capable of carrying and deploying the Münchhausen device, as the SG 104 was also known.

 

The fictional Do 217 F-0 is a kitbashing, using a Do 217 N fuselage, combined with the wings from a Do 217 K bomber, plus some modifications. What initially sounded like a simple plan soon turned into a improvisation mess: it took some time to realize that I had already donated the Do 217 K's BMW 801 engines to another project, an upgraded He 115... I did not want to use the nightfighter's more powerful DB 603s, and I was lucky to have an Italeri Ju 188 kit at hand which comes with optional BMW 801s and Jumo 211s. Transplanting these engines onto the Do 217's wings took some tailoring of the adapter plates, but was feasible. However, the BMW 801s from the Ju 188 kit have a flaw: they lack the engine's characteristic cooling fans... Another lucky find: I found two such parts in the scrap box, even though from different kits - one left over from another Italeri Do 217 K, the other one from what I assume is/was an Italeri 1:72 Fw 190 A/F. To make matters worse, one propeller from the Ju 188 kit was missing, so that I had to find a(nother) replacement. :-/

I eventually used something that looked like an 1:72 F6F Hellcat propeller, but I an not certain about this because I have never built this model...? With some trimming on the blades' trailing edges and other mods, the donor's overall look could be adapted to the Ju 188 benchmark. Both propellers were mounted on metal axis' so that they could also carry the cooling fans. Lots of work, but the result looks quite good.

 

The Do 217 N's hull lost the lower rear gunner position and its ventral gondola, which was faired over with a piece of styrene sheet. The pilot was taken OOB, the gunner in the rear position was replaced by a more blob-like crew member from the scrap box. The plan to add a navigator in the seat to the lower right of the pilot did not work out due to space shortage, but this figure would probably have been invisble, anyway.

All gun openings in the nose were filled and PSRed away, and a fairing for a bomb aiming device and a single gun (the barrel is a hollow steel needle) were added.

 

The SG 104 was scratched. Starting point was a white metal replacement barrel for an 1:35 ISU-152 SPG with a brass muzzle brake. However, after dry-fitting the barrel under the hull the barrel turned out to be much too wide, so that only the muzzal brake survived and the rest of the weapon was created from a buddy refueling pod (from an Italeri 1:72 Luftwaffe Tornado, because of its two conical ends) and protective plastic caps from medical canulas. To attach this creation to the hull I abused a conformal belly tank from a Matchbox Gloster Meteor night fighter and tailored it into a streamlined fairing. While this quite a Frankenstein creation, the overall dimensions match the real SG 104 prototype and its look well.

 

Other cosmetic modifications include a pair of underwing dive brakes, translanted from an Italeri 1:72 Ju 88 A-4 kit, an extended (scratched) tail "stinger" which resembles the real dive brake arrangement that was installed on some Do 217 E bombers, and I added blast deflector vanes and a dorsal stabilizer fin.

In order to provide the aircraft with enough ground clearance, the tail wheel was slightly extended. Thanks to the long tail stinger, this is not blatantly obvious.

  

Painting and markings:

This was not an easy choice, but as a kind of prototype I decided that the paint scheme should be rather conservative. However, German aircraft operating over the Atlantic tended to carry rather pale schemes, so that the standard pattern of RLM 70/71/65 (Dunkelgrün, Schwarzgrün and Hellblau) with a low waterline - typical for experimental types - would hardly be appropriate.

I eventually found a compromise on a He 177 bomber (coded 6N+BN) from 1944 that was operated by KG 100: this particular aircraft had a lightened upper camouflage - still a standard splinter scheme but consisting of RLM 71 and 02 (Dunkelgrün and Grau; I used Modelmaster 2081 and Humbrol 240), a combination that had been used on German fighters during the Battle of Britain when the standard colors turned out to be too dark for operations over the Channel. The aircraft also carried standard RLM 65 (or maybe the new RLM76) underneath (Humbrol 65) and on the fin, but with a very high and slightly wavy waterline. As a rather unusual feature, no typical camouflage mottles were carried on the flanks or the fin, giving the aircraft a very bleak and simple look.

 

Despite my fears that this might look rather boring I adapted this scheme for the Do 217 F-0, and once basic painting was completed I was rather pleased by the aircraft's look! As an aircraft operated at the Western front, no additional markings like fuselage bands were carried.

To set the SG 104 apart from the airframe, I painted the weapon's visible parts in RLM 66 (Schwarzgrau, Humbrol 67), because this tone was frequently used for machinery (including the interior surfaces of aircraft towards 1945).

RLM 02 was also used for the interior surfaces and the landing gear, even though I used a slightly different, lighter shade in form of Revell 45 (Helloliv).

 

A light black ink washing was applied and post-shading to emphasize panel lines. Most markings/decals came from a Begemot 1:72 He 11 sheet, including the unusual green tactical code - it belongs to a staff unit, a suitable marking for such an experimental aircraft. The green (Humbrol 2) was carried over to the tips of the propeller spinners. The unit's code "1A" is fictional, AFAIK this combination had never been used by the Luftwaffe.

The small unit badge was alucky find: it actually depicts the fictional Baron von Münchhausen riding on a cannonball, and it comes from an Academy 1:72 Me 163 kit and its respective sheet. The mission markings underneath, depicting two anti-ship missions plus a successful sinking, came from a TL Modellbau 1:72 scale sheet with generic German WWII victory markings.

 

After some soot stains around the engine exhaust and weapon muzzles had been added with graphite, the model was sealed with matt acrylic varnish and final details like position lights and wire antennae (from heated black plastic sprue material) were added.

  

Well, what started as a combination of two kits of the same kind with a simple huge pipe underneath turned out to be more demanding than expected. The (incomplete) replacement engines were quite a challenge, and body work on the hull (tail stinger, fairing for the SG 104 as well as the weapon itself) turned out to be more complex and extensive than initially thought of. The result looks quite convincing, also supported by the rather simple paint scheme which IMHO just "looks right" and very convincing. And the whole thing is probably the most direct representation of the inspiring "Gunship" theme!

 

I did a little more work on my model tonight. I didn't do a lot as I wanted to spend some time on Flickr this evening too. I did a second coat of paint on the window ledges on the side wall parts. I'll probably start assembly of the building tomorrow. :D

Some background:

The English Electric Skyspark was a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2. The Skyspark was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Skyspark.

 

The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 program. W.E.W. "Teddy" Petter, formerly chief designer at Westland Aircraft, was a keen early proponent of Britain's need to develop a supersonic fighter aircraft. In 1947, Petter approached the Ministry of Supply (MoS) with his proposal, and in response Specification ER.103 was issued for a single research aircraft, which was to be capable of flight at Mach 1.5 (1,593 km/h) and 50,000 ft (15,000 m).

 

Petter initiated a design proposal with F W "Freddie" Page leading the design and Ray Creasey responsible for the aerodynamics. As it was designed for Mach 1.5, it had a 40° swept wing to keep the leading edge clear of the Mach cone. To mount enough power into the airframe, two engines were installed, in an unusual, stacked layout and with a high tailplane This proposal was submitted in November 1948, and in January 1949 the project was designated P.1 by English Electric. On 29 March 1949 MoS granted approval to start the detailed design, develop wind tunnel models and build a full-size mock-up.

 

The design that had developed during 1948 evolved further during 1949 to further improve performance. To achieve Mach 2 the wing sweep was increased to 60° with the ailerons moved to the wingtips. In late 1949, low-speed wind tunnel tests showed that a vortex was generated by the wing which caused a large downwash on the initial high tailplane; this issue was solved by lowering the tail below the wing. Following the resignation of Petter, Page took over as design team leader for the P.1. In 1949, the Ministry of Supply had issued Specification F23/49, which expanded upon the scope of ER103 to include fighter-level manoeuvring. On 1 April 1950, English Electric received a contract for two flying airframes, as well as one static airframe, designated P.1.

 

The Royal Aircraft Establishment disagreed with Petter's choice of sweep angle (60 degrees) and the stacked engine layout, as well as the low tailplane position, was considered to be dangerous, too. To assess the effects of wing sweep and tailplane position on the stability and control of Petter's design Short Brothers were issued a contract, by the Ministry of Supply, to produce the Short SB.5 in mid-1950. This was a low-speed research aircraft that could test sweep angles from 50 to 69 degrees and tailplane positions high or low. Testing with the wings and tail set to the P.1 configuration started in January 1954 and confirmed this combination as the correct one. The proposed 60-degree wing sweep was retained, but the stacked engines had to give way to a more conventional configuration with two engines placed side-by-side in the tail, but still breathing through a mutual nose air intake.

 

From 1953 onward, the first three prototype aircraft were hand-built at Samlesbury. These aircraft had been assigned the aircraft serials WG760, WG763, and WG765 (the structural test airframe). The prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, as the selected Rolls-Royce Avon engines had fallen behind schedule due to their own development problems. Since there was not much space in the fuselage for fuel, the thin wings became the primary fuel tanks and since they also provided space for the stowed main undercarriage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance. The narrow tires housed in the thin wings rapidly wore out if there was any crosswind component during take-off or landing. Outwardly, the prototypes looked very much like the production series, but they were distinguished by the rounded-triangular air intake with no center-body at the nose, short fin, and lack of operational equipment.

 

On 9 June 1952, it was decided that there would be a second phase of prototypes built to develop the aircraft toward achieving Mach 2.0 (2,450 km/h); these were designated P.1B while the initial three prototypes were retroactively reclassified as P.1A. P.1B was a significant improvement on P.1A. While it was similar in aerodynamics, structure and control systems, it incorporated extensive alterations to the forward fuselage, reheated Rolls Royce Avon R24R engines, a conical center body inlet cone, variable nozzle reheat and provision for weapons systems integrated with the ADC and AI.23 radar. Three P.1B prototypes were built, assigned serials XA847, XA853 and XA856.

 

In May 1954, WG760 and its support equipment were moved to RAF Boscombe Down for pre-flight ground taxi trials; on the morning of 4 August 1954, WG760 flew for the first time from Boscombe Down. One week later, WG760 officially achieved supersonic flight for the first time, having exceeded the speed of sound during its third flight. While WG760 had proven the P.1 design to be viable, it was plagued by directional stability problems and a dismal performance: Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of just 48,000 ft (14,630 m), far below the requirements.

 

To solve the problem and save the P.1, Petter embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed a new, narrower canopy, a revised air intake, a pair of stabilizing fins under the rear fuselage, and a shallow ventral fairing at the wings’ trailing edge that not only reduced the drag coefficient along the wing/fuselage intersection, it also provided space for additional fuel.

On 4 April 1957 the modified P.1B (XA847) made the first flight, immediately exceeding Mach 1. During the early flight trials of the P.1B, speeds in excess of 1,000 mph were achieved daily.

In late October 1958, the plane was officially presented. The event was celebrated in traditional style in a hangar at Royal Aircraft Establishment (RAE) Farnborough, with the prototype XA847 having the name ‘Skyspark’ freshly painted on the nose in front of the RAF Roundel, which almost covered it. A bottle of champagne was put beside the nose on a special rig which allowed the bottle to safely be smashed against the side of the aircraft.

On 25 November 1958 the P.1B XA847 reached Mach 2 for the first time. This made it the second Western European aircraft to reach Mach 2, the first one being the French Dassault Mirage III just over a month earlier on 24 October 1958

 

The first operational Skyspark, designated Skyspark F.1, was designed as a pure interceptor to defend the V Force airfields in conjunction with the "last ditch" Bristol Bloodhound missiles located either at the bomber airfield, e.g. at RAF Marham, or at dedicated missile sites near to the airfield, e.g. at RAF Woodhall Spa near the Vulcan station RAF Coningsby. The bomber airfields, along with the dispersal airfields, would be the highest priority targets in the UK for enemy nuclear weapons. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range – originally a radius of operation of only 150 miles (240 km) from the V bomber airfields was specified – and endurance. Armament consisted of a pair of 30 mm ADEN cannon in front of the cockpit, and two pylons for IR-guided de Havilland Firestreak air-to-air missiles were added to the lower fuselage flanks. These hardpoints could, alternatively, carry pods with unguided 55 mm air-to-air rockets. The Ferranti AI.23 onboard radar provided missile guidance and ranging, as well as search and track functions.

 

The next two Skyspark variants, the Skyspark F.1A and F.2, incorporated relatively minor design changes, but for the next variant, the Skyspark F.3, they were more extensive: The F.3 had higher thrust Rolls-Royce Avon 301R engines, a larger squared-off fin that improved directional stability at high speed further and a strengthened inlet cone allowing a service clearance to Mach 2.0 (2,450 km/h; the F.1, F.1A and F.2 were all limited to Mach 1.7 (2,083 km/h). An upgraded A.I.23B radar and new, radar-guided Red Top missiles offered a forward hemisphere attack capability, even though additional electronics meant that the ADEN guns had to be deleted – but they were not popular in their position in front of the windscreen, because the muzzle flash blinded the pilot upon firing. The new engines and fin made the F.3 the highest performance Skyspark yet, but this came at a steep price: higher fuel consumption, resulting in even shorter range. From this basis, a conversion trainer with a side-by-side cockpit, the T.4, was created.

 

The next interceptor variant was already in development, but there was a need for an interim solution to partially address the F.3's shortcomings, the F.3A. The F.3A introduced two major improvements: a larger, non-jettisonable, 610-imperial-gallon (2,800 L) ventral fuel tank, resulting in a much deeper and longer belly fairing, and a new, kinked, conically cambered wing leading edge. The conically cambered wing improved manoeuvrability, especially at higher altitudes, and it offered space for a slightly larger leading edge fuel tank, raising the total usable internal fuel by 716 imperial gallons (3,260 L). The enlarged ventral tank not only nearly doubled available fuel, it also provided space at its front end for a re-instated pair of 30 mm ADEN cannon with 120 RPG. Alternatively, a retractable pack with unguided 55 mm air-to-air rockets could be installed, or a set of cameras for reconnaissance missions. The F.3A also introduced an improved A.I.23B radar and the new IR-guided Red Top missile, which was much faster and had greater range and manoeuvrability than the Firestreak. Its improved infrared seeker enabled a wider range of engagement angles and offered a forward hemisphere attack capability that would allow the Skyspark to attack even faster bombers (like the new, supersonic Tupolev T-22 Blinder) through a collision-course approach.

Wings and the new belly tank were also immediately incorporated in a second trainer variant, the T.5.

 

The ultimate variant, the Skyspark F.6, was nearly identical to the F.3A, with the exception that it could carry two additional 260-imperial-gallon (1,200 L) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency and gave the F.6 a substantially improved deployment capability, even though their supersonic drag was so high that the extra fuel would only marginally raise the aircraft’s range when flying beyond the sound barrier for extended periods.

 

Finally, there was the Skyspark F.2A; it was an early production F.2 upgraded with the new cambered wing, the squared fin, and the 610 imperial gallons (2,800 L) ventral tank. However, the F.2A retained the old AI.23 radar, the IR-guided Firestreak missile and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Skysparks, it had the longest tactical range of all variants, and was used for low-altitude interception over West Germany.

 

The first Skysparks to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Skyspark for entry into service. The production Skyspark F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Skyspark F.1 entered frontline squadron service with 74 Squadron at Coltishall from 11 July 1960. This made the Skyspark the second Western European-built combat aircraft with true supersonic capability to enter service and the second fully supersonic aircraft to be deployed in Western Europe (the first one in both categories being the Swedish Saab 35 Draken on 8 March 1960 four months earlier).

 

The aircraft's radar and missiles proved to be effective, and pilots reported that the Skyspark was easy to fly. However, in the first few months of operation the aircraft's serviceability was extremely poor. This was due to the complexity of the aircraft systems and shortages of spares and ground support equipment. Even when the Skyspark was not grounded by technical faults, the RAF initially struggled to get more than 20 flying hours per aircraft per month compared with the 40 flying hours that English Electric believed could be achieved with proper support. In spite of these concerns, within six months of the Skyspark entering service, 74 Squadron was able to achieve 100 flying hours per aircraft.

 

Deliveries of the slightly improved Skyspark F.1A, with revised avionics and provision for an air-to-air refueling probe, allowed two more squadrons, 56 and 111 Squadron, both based at RAF Wattisham, to convert to the Skyspark in 1960–1961. The Skyspark F.1 was only ordered in limited numbers and served only for a short time; nonetheless, it was viewed as a significant step forward in Britain's air defence capabilities. Following their replacement from frontline duties by the introduction of successively improved Skyspark variants, the remaining F.1 aircraft were employed by the Skyspark Conversion Squadron.

The improved F.2 entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the of the two-seat T.4 and T.5 trainers (based on the F.3 and F.3A/F.6 fighters), which entered service with the Skyspark Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two-seater, small numbers were also allocated to the front-line fighter squadrons. More F.2s were produced than there were available squadron slots, so later production aircraft were stored for years before being used operationally; some of these Skyspark F.2s were converted to F.2As.

 

The F.3, with more powerful engines and the new Red Top missile was expected to be the definitive Skyspark, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. However, the F.3 also had only a short operational life and was withdrawn from service early due to defence cutbacks and the introduction of the even more capable and longer-range F.6, some of which were converted F.3s.

 

The introduction of the F.3 and F.6 allowed the RAF to progressively reequip squadrons operating aircraft such as the subsonic Gloster Javelin and retire these types during the mid-1960s. During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Skyspark's range and firepower shortcomings became increasingly apparent. The transfer of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force, alongside those withdrawn from Germany as they were replaced by SEPECAT Jaguars in the ground attack role.

The Skyspark's direct replacement was the Tornado F.3, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Skyspark, including far larger weapons load and considerably more advanced avionics. Skysparks were slowly phased out of service between 1974 and 1988, even though they lasted longer than expected because the definitive Tornado F.3 went through serious teething troubles and its service introduction was delayed several times. In their final years, the Skysparks’ airframes required considerable maintenance to keep them airworthy due to the sheer number of accumulated flight hours.

The kit and its assembly:

This build was a submission to the “Hunter, Lightning, Canberra” group build at whatifmodellers.com, and one of my personal ultimate challenges – a project that you think about very often, but the you put the thought back into its box when you realize that turning this idea into hardware will be a VERY tedious, complex and work-intensive task. But the thematic group build was the perfect occasion to eventually tackle the idea of a model of a “side-by-side engine BAC Lightning”, a.k.a. “Flatning”, as a rather conservative alternative to the real aircraft’s unique and unusual design with stacked engines in the fuselage, which brought a multitude of other design consequences that led to a really unique aircraft.

 

And it sound so simple: take a Lightning, just change the tail section. But it’s not that simple, because the whole fuselage shape would be different, resulting in less depth, the wings have to be attached somewhere and somehow, the landing gear might have to be adjusted/shortened, and how the fuselage diameter shape changes along the hull, so that you get a more or less smooth shape, was also totally uncertain!

 

Initially I considered a MiG Ye-152 as a body donor, but that was rejected due to the sheer price of the only available kit (ModelSvit). A Chinese Shenyang J-8I would also have been ideal – but there’s not 1:72 kit of this aircraft around, just of its successor with side intakes, a 1:72 J-8II from trumpeter.

I eventually decided to keep costs low, and I settled for the shaggy PM Model Su-15 (marketed as Su-21) “Flagon” as main body donor: it’s cheap, the engines have a good size for Avons and the pen nib fairing has a certain retro touch that goes well with the Lightning’s Fifties design.

The rest of this "Flatning" came from a Hasegawa 1:72 BAC Lightning F.6 (Revell re-boxing).

 

Massive modifications were necessary and lots of PSR. In an initial step the Flagon lost its lower wing halves, which are an integral part of the lower fuselage half. The cockpit section was cut away where the intake ducts begin. The Lightning had its belly tank removed (set aside for a potential later re-installation), and dry-fitting and crude measures suggested that only the cockpit section from the Lightning, its spine and the separate fin would make it onto the new fuselage.

 

Integrating the parts was tough, though! The problem that caused the biggest headaches: how to create a "smooth" fuselage from the Lightning's rounded front end with a single nose intake that originally develops into a narrow, vertical hull, combined with the boxy and rather wide Flagon fuselage with large Phantom-esque intakes? My solution: taking out deep wedges from all (rather massive) hull parts along the intake ducts, bend the leftover side walls inwards and glue them into place, so that the width becomes equal with the Lightning's cockpit section. VERY crude and massive body work!

 

However, the Lightning's cockpit section for the following hull with stacked engines is much deeper than the Flagon's side-by-side layout. My initial idea was to place the cockpit section higher, but I would have had to transplant a part of the Lightning's upper fuselage (with the spine on top, too!) onto the "flat" Flagon’s back. But this would have looked VERY weird, and I'd have had to bridge the round ventral shape of the Lightning into the boxy Flagon underside, too. This was no viable option, so that the cockpit section had to be further modified; I cut away the whole ventral cockpit section, at the height of the lower intake lip. Similar to my former Austrian Hasegawa Lightning, I also cut away the vertical bulkhead directly behind the intake opening - even though I did not improve the cockpit with a better tub with side consoles. At the back end, the Flagon's jet exhausts were opened and received afterburner dummies inside as a cosmetic upgrade.

 

Massive PSR work followed all around the hull. The now-open area under the cockpit was filled with lead beads to keep the front wheel down, and I implanted a landing gear well (IIRC, it's from an Xtrakit Swift). With the fuselage literally taking shape, the wings were glued together and the locator holes for the overwing tanks filled, because they would not be mounted.

 

To mount the wings to the new hull, crude measurements suggested that wedges had to be cut away from the Lightning's wing roots to match the weird fuselage shape. They were then glued to the shoulders, right behind the cockpit due to the reduced fuselage depth. At this stage, the Lightning’s stabilizer attachment points were transplanted, so that they end up in a similar low position on the rounded Su-15 tail. Again, lots of PSR…

 

At this stage I contemplated the next essential step: belly tank or not? The “Flatning” would have worked without it, but its profile would look rather un-Lightning-ish and rather “flat”. On the other side, a conformal tank would probably look quite strange on the new wide and flat ventral fuselage...? Only experiments could yield an answer, so I glued together the leftover belly bulge parts from the Hasegawa kit and played around with it. I considered a new, wider belly tank, but I guess that this would have looked too ugly. I eventually settled upon the narrow F.6 tank and also used the section behind it with the arrestor hook. I just reduced its depth by ~2 mm, with a slight slope towards the rear because I felt (righteously) that the higher wing position would lower the model’s stance. More massive PSR followed….

 

Due to the expected poor ground clearance, the Lightning’s stabilizing ventral fins were mounted directly under the fuselage edges rather than on the belly tank. Missile pylons for Red Tops were mounted to the lower front fuselage, similar to the real arrangement, and cable fairings, scratched from styrene profiles, were added to the lower flanks, stretching the hull optically and giving more structure to the hull.

 

To my surprise, I did not have to shorten the landing gear’s main legs! The wings ended up a little higher on the fuselage than on the original Lightning, and the front wheel sits a bit further back and deeper inside of its donor well, too, so that the fuselage comes probably 2 mm closer to the ground than an OOB Lightning model. Just like on the real aircraft, ground clearance is marginal, but when the main wheels were finally in place, the model turned out to have a low but proper stance, a little F8U-ish.

  

Painting and markings:

I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.

A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.

 

After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.

 

Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.

  

A major effort, and I have seriously depleted my putty stocks for this build! However, the result looks less spectacular than it actually is: changing a Lightning from its literally original stacked engine layout into a more conservative side-by-side arrangement turned out to be possible, even though the outcome is not really pretty. But it works and is feasible!

Some background:

The OV-10 Bronco was initially conceived in the early 1960s through an informal collaboration between W. H. Beckett and Colonel K. P. Rice, U.S. Marine Corps, who met at Naval Air Weapons Station China Lake, California, and who also happened to live near each other. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations. At the time, the U.S. Army was still experimenting with armed helicopters, and the U.S. Air Force was not interested in close air support.

The concept aircraft was to operate from expedient forward air bases using roads as runways. Speed was to be from very slow to medium subsonic, with much longer loiter times than a pure jet. Efficient turboprop engines would give better performance than piston engines. Weapons were to be mounted on the centerline to get efficient aiming. The inventors favored strafing weapons such as self-loading recoilless rifles, which could deliver aimed explosive shells with less recoil than cannons, and a lower per-round weight than rockets. The airframe was to be designed to avoid the back blast.

 

Beckett and Rice developed a basic platform meeting these requirements, then attempted to build a fiberglass prototype in a garage. The effort produced enthusiastic supporters and an informal pamphlet describing the concept. W. H. Beckett, who had retired from the Marine Corps, went to work at North American Aviation to sell the aircraft.

The aircraft's design supported effective operations from forward bases. The OV-10 had a central nacelle containing a crew of two in tandem and space for cargo, and twin booms containing twin turboprop engines. The visually distinctive feature of the aircraft is the combination of the twin booms, with the horizontal stabilizer that connected them at the fin tips. The OV-10 could perform short takeoffs and landings, including on aircraft carriers and large-deck amphibious assault ships without using catapults or arresting wires. Further, the OV-10 was designed to take off and land on unimproved sites. Repairs could be made with ordinary tools. No ground equipment was required to start the engines. And, if necessary, the engines would operate on high-octane automobile fuel with only a slight loss of power.

 

The aircraft had responsive handling and could fly for up to 5½ hours with external fuel tanks. The cockpit had extremely good visibility for both pilot and co-pilot, provided by a wrap-around "greenhouse" that was wider than the fuselage. North American Rockwell custom ejection seats were standard, with many successful ejections during service. With the second seat removed, the OV-10 could carry 3,200 pounds (1,500 kg) of cargo, five paratroopers, or two litter patients and an attendant. Empty weight was 6,969 pounds (3,161 kg). Normal operating fueled weight with two crew was 9,908 pounds (4,494 kg). Maximum takeoff weight was 14,446 pounds (6,553 kg).

The bottom of the fuselage bore sponsons or "stub wings" that improved flight performance by decreasing aerodynamic drag underneath the fuselage. Normally, four 7.62 mm (.308 in) M60C machine guns were carried on the sponsons, accessed through large forward-opening hatches. The sponsons also had four racks to carry bombs, pods, or fuel. The wings outboard of the engines contained two additional hardpoints, one per side. Racked armament in the Vietnam War was usually seven-shot 2.75 in (70 mm) rocket pods with white phosphorus marker rounds or high-explosive rockets, or 5" (127 mm) four-shot Zuni rocket pods. Bombs, ADSIDS air-delivered/para-dropped unattended seismic sensors, Mk-6 battlefield illumination flares, and other stores were also carried.

Operational experience showed some weaknesses in the OV-10's design. It was significantly underpowered, which contributed to crashes in Vietnam in sloping terrain because the pilots could not climb fast enough. While specifications stated that the aircraft could reach 26,000 feet (7,900 m), in Vietnam the aircraft could reach only 18,000 feet (5,500 m). Also, no OV-10 pilot survived ditching the aircraft.

 

The OV-10 served in the U.S. Air Force, U.S. Marine Corps, and U.S. Navy, as well as in the service of a number of other countries. In U.S. military service, the Bronco was operated until the early Nineties, and obsoleted USAF OV-10s were passed on to the Bureau of Alcohol, Tobacco, and Firearms for anti-drug operations. A number of OV-10As furthermore ended up in the hands of the California Department of Forestry (CDF) and were used for spotting fires and directing fire bombers onto hot spots.

 

This was not the end of the OV-10 in American military service, though: In 2012, the type gained new attention because of its unique qualities. A $20 million budget was allocated to activate an experimental USAF unit of two airworthy OV-10Gs, acquired from NASA and the State Department. These machines were retrofitted with military equipment and were, starting in May 2015, deployed overseas to support Operation “Inherent Resolve”, flying more than 120 combat sorties over 82 days over Iraq and Syria. Their concrete missions remained unclear, and it is speculated they provided close air support for Special Forces missions, esp. in confined urban environments where the Broncos’ loitering time and high agility at low speed and altitude made them highly effective and less vulnerable than helicopters.

Furthermore, these Broncos reputedly performed strikes with the experimental AGR-20A “Advanced Precision Kill Weapons System (APKWS)”, a Hydra 70-millimeter rocket with a laser-seeking head as guidance - developed for precision strikes against small urban targets with little collateral damage. The experiment ended satisfactorily, but the machines were retired again, and the small unit was dissolved.

 

However, the machines had shown their worth in asymmetric warfare, and the U.S. Air Force decided to invest in reactivating the OV-10 on a regular basis, despite the overhead cost of operating an additional aircraft type in relatively small numbers – but development and production of a similar new type would have caused much higher costs, with an uncertain time until an operational aircraft would be ready for service. Re-activating a proven design and updating an existing airframe appeared more efficient.

The result became the MV-10H, suitably christened “Super Bronco” but also known as “Black Pony”, after the program's internal name. This aircraft was derived from the official OV-10X proposal by Boeing from 2009 for the USAF's Light Attack/Armed Reconnaissance requirement. Initially, Boeing proposed to re-start OV-10 manufacture, but this was deemed uneconomical, due to the expected small production number of new serial aircraft, so the “Black Pony” program became a modernization project. In consequence, all airframes for the "new" MV-10Hs were recovered OV-10s of various types from the "boneyard" at Davis-Monthan Air Force Base in Arizona.

 

While the revamped aircraft would maintain much of its 1960s-vintage rugged external design, modernizations included a completely new, armored central fuselage with a highly modified cockpit section, ejection seats and a computerized glass cockpit. The “Black Pony” OV-10 had full dual controls, so that either crewmen could steer the aircraft while the other operated sensors and/or weapons. This feature would also improve survivability in case of incapacitation of a crew member as the result from a hit.

The cockpit armor protected the crew and many vital systems from 23mm shells and shrapnel (e. g. from MANPADS). The crew still sat in tandem under a common, generously glazed canopy with flat, bulletproof panels for reduced sun reflections, with the pilot in the front seat and an observer/WSO behind. The Bronco’s original cargo capacity and the rear door were retained, even though the extra armor and defensive measures like chaff/flare dispensers as well as an additional fuel cell in the central fuselage limited the capacity. However, it was still possible to carry and deploy personnel, e. g. small special ops teams of up to four when the aircraft flew in clean configuration.

Additional updates for the MV-10H included structural reinforcements for a higher AUW and higher g load maneuvers, similar to OV-10D+ standards. The landing gear was also reinforced, and the aircraft kept its ability to operate from short, improvised airstrips. A fixed refueling probe was added to improve range and loiter time.

 

Intelligence sensors and smart weapon capabilities included a FLIR sensor and a laser range finder/target designator, both mounted in a small turret on the aircraft’s nose. The MV-10H was also outfitted with a data link and the ability to carry an integrated targeting pod such as the Northrop Grumman LITENING or the Lockheed Martin Sniper Advanced Targeting Pod (ATP). Also included was the Remotely Operated Video Enhanced Receiver (ROVER) to provide live sensor data and video recordings to personnel on the ground.

 

To improve overall performance and to better cope with the higher empty weight of the modified aircraft as well as with operations under hot-and-high conditions, the engines were beefed up. The new General Electric CT7-9D turboprop engines improved the Bronco's performance considerably: top speed increased by 100 mph (160 km/h), the climb rate was tripled (a weak point of early OV-10s despite the type’s good STOL capability) and both take-off as well as landing run were almost halved. The new engines called for longer nacelles, and their circular diameter markedly differed from the former Garrett T76-G-420/421 turboprop engines. To better exploit the additional power and reduce the aircraft’s audio signature, reversible contraprops, each with eight fiberglass blades, were fitted. These allowed a reduced number of revolutions per minute, resulting in less noise from the blades and their tips, while the engine responsiveness was greatly improved. The CT7-9Ds’ exhausts were fitted with muzzlers/air mixers to further reduce the aircraft's noise and heat signature.

Another novel and striking feature was the addition of so-called “tip sails” to the wings: each wingtip was elongated with a small, cigar-shaped fairing, each carrying three staggered, small “feather blade” winglets. Reputedly, this installation contributed ~10% to the higher climb rate and improved lift/drag ratio by ~6%, improving range and loiter time, too.

Drawing from the Iraq experience as well as from the USMC’s NOGS test program with a converted OV-10D as a night/all-weather gunship/reconnaissance platform, the MV-10H received a heavier gun armament: the original four light machine guns that were only good for strafing unarmored targets were deleted and their space in the sponsons replaced by avionics. Instead, the aircraft was outfitted with a lightweight M197 three-barrel 20mm gatling gun in a chin turret. This could be fixed in a forward position at high speed or when carrying forward-firing ordnance under the stub wings, or it could be deployed to cover a wide field of fire under the aircraft when it was flying slower, being either slaved to the FLIR or to a helmet sighting auto targeting system.

The original seven hardpoints were retained (1x ventral, 2x under each sponson, and another pair under the outer wings), but the total ordnance load was slightly increased and an additional pair of launch rails for AIM-9 Sidewinders or other light AAMs under the wing tips were added – not only as a defensive measure, but also with an anti-helicopter role in mind; four more Sidewinders could be carried on twin launchers under the outer wings against aerial targets. Other guided weapons cleared for the MV-10H were the light laser-guided AGR-20A and AGM-119 Hellfire missiles, the Advanced Precision Kill Weapon System upgrade to the light Hydra 70 rockets, the new Laser Guided Zuni Rocket which had been cleared for service in 2010, TV-/IR-/laser-guided AGM-65 Maverick AGMs and AGM-122 Sidearm anti-radar missiles, plus a wide range of gun and missile pods, iron and cluster bombs, as well as ECM and flare/chaff pods, which were not only carried defensively, but also in order to disrupt enemy ground communication.

 

In this configuration, a contract for the conversion of twelve mothballed American Broncos to the new MV-10H standard was signed with Boeing in 2016, and the first MV-10H was handed over to the USAF in early 2018, with further deliveries lasting into early 2020. All machines were allocated to the newly founded 919th Special Operations Support Squadron at Duke Field (Florida). This unit was part of the 919th Special Operations Wing, an Air Reserve Component (ARC) of the United States Air Force. It was assigned to the Tenth Air Force of Air Force Reserve Command and an associate unit of the 1st Special Operations Wing, Air Force Special Operations Command (AFSOC). If mobilized the wing was gained by AFSOC (Air Force Special Operations Command) to support Special Tactics, the U.S. Air Force's special operations ground force. Similar in ability and employment to Marine Special Operations Command (MARSOC), U.S. Army Special Forces and U.S. Navy SEALs, Air Force Special Tactics personnel were typically the first to enter combat and often found themselves deep behind enemy lines in demanding, austere conditions, usually with little or no support.

 

The MV-10Hs are expected to provide support for these ground units in the form of all-weather reconnaissance and observation, close air support and also forward air control duties for supporting ground units. Precision ground strikes and protection from enemy helicopters and low-flying aircraft were other, secondary missions for the modernized Broncos, which are expected to serve well into the 2040s. Exports or conversions of foreign OV-10s to the Black Pony standard are not planned, though.

The kit and its assembly:

This fictional Bronco update/conversion was simply spawned by the idea: could it be possible to replace the original cockpit section with one from an AH-1 Cobra, for a kind of gunship version?

 

The basis is the Academy OV-10D kit, mated with the cockpit section from a Fujimi AH-1S TOW Cobra (Revell re-boxing, though), chosen because of its “boxy” cockpit section with flat glass panels – I think that it conveys the idea of an armored cockpit section best. Combining these parts was not easy, though, even though the plan sound simple. Initially, the Bronco’s twin booms, wings and stabilizer were built separately, because this made PSR on these sections easier than trying the same on a completed airframe. One of the initial challenges: the different engines. I wanted something uprated, and a different look, and I had a pair of (excellent!) 1:144 resin engines from the Russian company Kompakt Zip for a Tu-95 bomber at hand, which come together with movable(!) eight-blade contraprops that were an almost perfect size match for the original three-blade props. Biggest problem: the Tu-95 nacelles have a perfectly circular diameter, while the OV-10’s booms are square and rectangular. Combining these parts and shapes was already a messy PST affair, but it worked out quite well – even though the result rather reminds of some Chinese upgrade measure (anyone know the Tu-4 copies with turboprops? This here looks similar!). But while not pretty, I think that the beafier look works well and adds to the idea of a “revived” aircraft. And you can hardly beat the menacing look of contraprops on anything...

The exotic, so-called “tip sails” on the wings, mounted on short booms, are a detail borrowed from the Shijiazhuang Y-5B-100, an updated Chinese variant/copy of the Antonov An-2 biplane transporter. The booms are simple pieces of sprue from the Bronco kit, the winglets were cut from 0.5mm styrene sheet.

 

For the cockpit donor, the AH-1’s front section was roughly built, including the engine section (which is a separate module, so that the basic kit can be sold with different engine sections), and then the helicopter hull was cut and trimmed down to match the original Bronco pod and to fit under the wing. This became more complicated than expected, because a) the AH-1 cockpit and the nose are considerably shorter than the OV-10s, b) the AH-1 fuselage is markedly taller than the Bronco’s and c) the engine section, which would end up in the area of the wing, features major recesses, making the surface very uneven – calling for massive PSR to even this out. PSR was also necessary to hide the openings for the Fujimi AH-1’s stub wings. Other issues: the front landing gear (and its well) had to be added, as well as the OV-10 wing stubs. Furthermore, the new cockpit pod’s rear section needed an aerodynamical end/fairing, but I found a leftover Academy OV-10 section from a build/kitbashing many moons ago. Perfect match!

All these challenges could be tackled, even though the AH-1 cockpit looks surprisingly stout and massive on the Bronco’s airframe - the result looks stockier than expected, but it works well for the "Gunship" theme. Lots of PSR went into the new central fuselage section, though, even before it was mated with the OV-10 wing and the rest of the model.

Once cockpit and wing were finally mated, the seams had to disappear under even more PSR and a spinal extension of the canopy had to be sculpted across the upper wing surface, which would meld with the pod’s tail in a (more or less) harmonious shape. Not an easy task, and the fairing was eventually sculpted with 2C putty, plus even more PSR… Looks quite homogenous, though.

 

After this massive body work, other hardware challenges appeared like small distractions. The landing gear was another major issue because the deeper AH-1 section lowered the ground clearance, also because of the chin turret. To counter this, I raised the OV-10’s main landing gear by ~2mm – not much, but it was enough to create a credible stance, together with the front landing gear transplant under the cockpit, which received an internal console to match the main landing gear’s length. Due to the chin turret and the shorter nose, the front wheel retracts backwards now. But this looks quite plausible, thanks to the additional space under the cockpit tub, which also made a belt feed for the gun’s ammunition supply believable.

To enhance the menacing look I gave the model a fixed refueling boom, made from 1mm steel wire and a receptor adapter sculpted with white glue. The latter stuff was also used add some antenna fairings around the hull. Some antennae, chaff dispensers and an IR decoy were taken from the Academy kit.

 

The ordnance came from various sources. The Sidewinders under the wing tips were taken from an Italeri F-16C/D kit, they look better than the missiles from the Academy Bronco kit. Their launch rails came from an Italeri Bae Hawk 200. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-10 and -19 missile pods on the stub wings were taken from the OV-10 kit.

  

Painting and markings:

Finding a suitable and somewhat interesting – but still plausible – paint scheme was not easy. Taking the A-10 as benchmark, an overall light grey livery (with focus on low contrast against the sky as protection against ground fire) would have been a likely choice – and in fact the last operational American OV-10s were painted in this fashion. But in order to provide a different look I used the contemporary USAF V-22Bs and Special Operations MC-130s as benchmark, which typically carry a darker paint scheme consisting of FS 36118 (suitably “Gunship Gray” :D) from above, FS 36375 underneath, with a low, wavy waterline, plus low-viz markings. Not spectacular, but plausible – and very similar to the late r/w Colombian OV-10s.

The cockpit tub became Dark Gull Grey (FS 36231, Humbrol 140) and the landing gear white (Revell 301).

 

The model received an overall black ink washing and some post-panel-shading, to liven up the dull all-grey livery. The decals were gathered from various sources, and I settled for black USAF low-viz markings. The “stars and bars” come from a late USAF F-4, the “IP” tail code was tailored from F-16 markings and the shark mouth was taken from an Academy AH-64. Most stencils came from another Academy OV-10 sheet and some other sources.

Decals were also used to create the trim on the propeller blades and markings on the ordnance.

 

Finally, the model was sealed with a coat of matt acrylic varnish (Italeri) and some exhaust soot stains were added with graphite along the tail boom flanks.

  

A successful transplantation – but is this still a modified Bronco or already a kitbashing? The result looks quite plausible and menacing, even though the TOW Cobra front section appears relatively massive. But thanks to the bigger engines and extended wing tips the proportions still work. The large low-pressure tires look a bit goofy under the aircraft, but they are original. The grey livery works IMHO well, too – a more colorful or garish scheme would certainly have distracted from the modified technical basis.

W&W 120 has had a colorful life...

 

Being built in December of 1957 as Pennsylvania Railroad ALCO RS11 #8647, it then survived into Penn Central, being renumbered to 7647. Once more, originally PRR 8647, now PC 7647 survived into Conrail and retaining its PC number, became CR 7647

 

CR 7647 was converted into an MT4 slug sometime between 1977 and 1991 and renumbered to CR 1020.

 

It was then sold off to the Winchester and Western sometime between August of 1994 and January of 1995.

 

Another interesting feature is the SW1500 cab on top of the slug...which was performed sometime between December of 2003 and November of 2005. The cab is off of an IHB SW1500 (as to which SW1500, I don't not know - yet)

 

Here, in 2013 we now see that the engine is sitting within the confines of the Unimin Corporation just up the road from the engine facility at Gore, VA. Which is a sand mining business and one of the leading producers of non metallic minerals.

Some background:

The English Electric Skyspark was a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2. The Skyspark was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Skyspark.

 

The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 program. W.E.W. "Teddy" Petter, formerly chief designer at Westland Aircraft, was a keen early proponent of Britain's need to develop a supersonic fighter aircraft. In 1947, Petter approached the Ministry of Supply (MoS) with his proposal, and in response Specification ER.103 was issued for a single research aircraft, which was to be capable of flight at Mach 1.5 (1,593 km/h) and 50,000 ft (15,000 m).

 

Petter initiated a design proposal with F W "Freddie" Page leading the design and Ray Creasey responsible for the aerodynamics. As it was designed for Mach 1.5, it had a 40° swept wing to keep the leading edge clear of the Mach cone. To mount enough power into the airframe, two engines were installed, in an unusual, stacked layout and with a high tailplane This proposal was submitted in November 1948, and in January 1949 the project was designated P.1 by English Electric. On 29 March 1949 MoS granted approval to start the detailed design, develop wind tunnel models and build a full-size mock-up.

 

The design that had developed during 1948 evolved further during 1949 to further improve performance. To achieve Mach 2 the wing sweep was increased to 60° with the ailerons moved to the wingtips. In late 1949, low-speed wind tunnel tests showed that a vortex was generated by the wing which caused a large downwash on the initial high tailplane; this issue was solved by lowering the tail below the wing. Following the resignation of Petter, Page took over as design team leader for the P.1. In 1949, the Ministry of Supply had issued Specification F23/49, which expanded upon the scope of ER103 to include fighter-level manoeuvring. On 1 April 1950, English Electric received a contract for two flying airframes, as well as one static airframe, designated P.1.

 

The Royal Aircraft Establishment disagreed with Petter's choice of sweep angle (60 degrees) and the stacked engine layout, as well as the low tailplane position, was considered to be dangerous, too. To assess the effects of wing sweep and tailplane position on the stability and control of Petter's design Short Brothers were issued a contract, by the Ministry of Supply, to produce the Short SB.5 in mid-1950. This was a low-speed research aircraft that could test sweep angles from 50 to 69 degrees and tailplane positions high or low. Testing with the wings and tail set to the P.1 configuration started in January 1954 and confirmed this combination as the correct one. The proposed 60-degree wing sweep was retained, but the stacked engines had to give way to a more conventional configuration with two engines placed side-by-side in the tail, but still breathing through a mutual nose air intake.

 

From 1953 onward, the first three prototype aircraft were hand-built at Samlesbury. These aircraft had been assigned the aircraft serials WG760, WG763, and WG765 (the structural test airframe). The prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, as the selected Rolls-Royce Avon engines had fallen behind schedule due to their own development problems. Since there was not much space in the fuselage for fuel, the thin wings became the primary fuel tanks and since they also provided space for the stowed main undercarriage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance. The narrow tires housed in the thin wings rapidly wore out if there was any crosswind component during take-off or landing. Outwardly, the prototypes looked very much like the production series, but they were distinguished by the rounded-triangular air intake with no center-body at the nose, short fin, and lack of operational equipment.

 

On 9 June 1952, it was decided that there would be a second phase of prototypes built to develop the aircraft toward achieving Mach 2.0 (2,450 km/h); these were designated P.1B while the initial three prototypes were retroactively reclassified as P.1A. P.1B was a significant improvement on P.1A. While it was similar in aerodynamics, structure and control systems, it incorporated extensive alterations to the forward fuselage, reheated Rolls Royce Avon R24R engines, a conical center body inlet cone, variable nozzle reheat and provision for weapons systems integrated with the ADC and AI.23 radar. Three P.1B prototypes were built, assigned serials XA847, XA853 and XA856.

 

In May 1954, WG760 and its support equipment were moved to RAF Boscombe Down for pre-flight ground taxi trials; on the morning of 4 August 1954, WG760 flew for the first time from Boscombe Down. One week later, WG760 officially achieved supersonic flight for the first time, having exceeded the speed of sound during its third flight. While WG760 had proven the P.1 design to be viable, it was plagued by directional stability problems and a dismal performance: Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of just 48,000 ft (14,630 m), far below the requirements.

 

To solve the problem and save the P.1, Petter embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed a new, narrower canopy, a revised air intake, a pair of stabilizing fins under the rear fuselage, and a shallow ventral fairing at the wings’ trailing edge that not only reduced the drag coefficient along the wing/fuselage intersection, it also provided space for additional fuel.

On 4 April 1957 the modified P.1B (XA847) made the first flight, immediately exceeding Mach 1. During the early flight trials of the P.1B, speeds in excess of 1,000 mph were achieved daily.

In late October 1958, the plane was officially presented. The event was celebrated in traditional style in a hangar at Royal Aircraft Establishment (RAE) Farnborough, with the prototype XA847 having the name ‘Skyspark’ freshly painted on the nose in front of the RAF Roundel, which almost covered it. A bottle of champagne was put beside the nose on a special rig which allowed the bottle to safely be smashed against the side of the aircraft.

On 25 November 1958 the P.1B XA847 reached Mach 2 for the first time. This made it the second Western European aircraft to reach Mach 2, the first one being the French Dassault Mirage III just over a month earlier on 24 October 1958

 

The first operational Skyspark, designated Skyspark F.1, was designed as a pure interceptor to defend the V Force airfields in conjunction with the "last ditch" Bristol Bloodhound missiles located either at the bomber airfield, e.g. at RAF Marham, or at dedicated missile sites near to the airfield, e.g. at RAF Woodhall Spa near the Vulcan station RAF Coningsby. The bomber airfields, along with the dispersal airfields, would be the highest priority targets in the UK for enemy nuclear weapons. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range – originally a radius of operation of only 150 miles (240 km) from the V bomber airfields was specified – and endurance. Armament consisted of a pair of 30 mm ADEN cannon in front of the cockpit, and two pylons for IR-guided de Havilland Firestreak air-to-air missiles were added to the lower fuselage flanks. These hardpoints could, alternatively, carry pods with unguided 55 mm air-to-air rockets. The Ferranti AI.23 onboard radar provided missile guidance and ranging, as well as search and track functions.

 

The next two Skyspark variants, the Skyspark F.1A and F.2, incorporated relatively minor design changes, but for the next variant, the Skyspark F.3, they were more extensive: The F.3 had higher thrust Rolls-Royce Avon 301R engines, a larger squared-off fin that improved directional stability at high speed further and a strengthened inlet cone allowing a service clearance to Mach 2.0 (2,450 km/h; the F.1, F.1A and F.2 were all limited to Mach 1.7 (2,083 km/h). An upgraded A.I.23B radar and new, radar-guided Red Top missiles offered a forward hemisphere attack capability, even though additional electronics meant that the ADEN guns had to be deleted – but they were not popular in their position in front of the windscreen, because the muzzle flash blinded the pilot upon firing. The new engines and fin made the F.3 the highest performance Skyspark yet, but this came at a steep price: higher fuel consumption, resulting in even shorter range. From this basis, a conversion trainer with a side-by-side cockpit, the T.4, was created.

 

The next interceptor variant was already in development, but there was a need for an interim solution to partially address the F.3's shortcomings, the F.3A. The F.3A introduced two major improvements: a larger, non-jettisonable, 610-imperial-gallon (2,800 L) ventral fuel tank, resulting in a much deeper and longer belly fairing, and a new, kinked, conically cambered wing leading edge. The conically cambered wing improved manoeuvrability, especially at higher altitudes, and it offered space for a slightly larger leading edge fuel tank, raising the total usable internal fuel by 716 imperial gallons (3,260 L). The enlarged ventral tank not only nearly doubled available fuel, it also provided space at its front end for a re-instated pair of 30 mm ADEN cannon with 120 RPG. Alternatively, a retractable pack with unguided 55 mm air-to-air rockets could be installed, or a set of cameras for reconnaissance missions. The F.3A also introduced an improved A.I.23B radar and the new IR-guided Red Top missile, which was much faster and had greater range and manoeuvrability than the Firestreak. Its improved infrared seeker enabled a wider range of engagement angles and offered a forward hemisphere attack capability that would allow the Skyspark to attack even faster bombers (like the new, supersonic Tupolev T-22 Blinder) through a collision-course approach.

Wings and the new belly tank were also immediately incorporated in a second trainer variant, the T.5.

 

The ultimate variant, the Skyspark F.6, was nearly identical to the F.3A, with the exception that it could carry two additional 260-imperial-gallon (1,200 L) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency and gave the F.6 a substantially improved deployment capability, even though their supersonic drag was so high that the extra fuel would only marginally raise the aircraft’s range when flying beyond the sound barrier for extended periods.

 

Finally, there was the Skyspark F.2A; it was an early production F.2 upgraded with the new cambered wing, the squared fin, and the 610 imperial gallons (2,800 L) ventral tank. However, the F.2A retained the old AI.23 radar, the IR-guided Firestreak missile and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Skysparks, it had the longest tactical range of all variants, and was used for low-altitude interception over West Germany.

 

The first Skysparks to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Skyspark for entry into service. The production Skyspark F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Skyspark F.1 entered frontline squadron service with 74 Squadron at Coltishall from 11 July 1960. This made the Skyspark the second Western European-built combat aircraft with true supersonic capability to enter service and the second fully supersonic aircraft to be deployed in Western Europe (the first one in both categories being the Swedish Saab 35 Draken on 8 March 1960 four months earlier).

 

The aircraft's radar and missiles proved to be effective, and pilots reported that the Skyspark was easy to fly. However, in the first few months of operation the aircraft's serviceability was extremely poor. This was due to the complexity of the aircraft systems and shortages of spares and ground support equipment. Even when the Skyspark was not grounded by technical faults, the RAF initially struggled to get more than 20 flying hours per aircraft per month compared with the 40 flying hours that English Electric believed could be achieved with proper support. In spite of these concerns, within six months of the Skyspark entering service, 74 Squadron was able to achieve 100 flying hours per aircraft.

 

Deliveries of the slightly improved Skyspark F.1A, with revised avionics and provision for an air-to-air refueling probe, allowed two more squadrons, 56 and 111 Squadron, both based at RAF Wattisham, to convert to the Skyspark in 1960–1961. The Skyspark F.1 was only ordered in limited numbers and served only for a short time; nonetheless, it was viewed as a significant step forward in Britain's air defence capabilities. Following their replacement from frontline duties by the introduction of successively improved Skyspark variants, the remaining F.1 aircraft were employed by the Skyspark Conversion Squadron.

The improved F.2 entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the of the two-seat T.4 and T.5 trainers (based on the F.3 and F.3A/F.6 fighters), which entered service with the Skyspark Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two-seater, small numbers were also allocated to the front-line fighter squadrons. More F.2s were produced than there were available squadron slots, so later production aircraft were stored for years before being used operationally; some of these Skyspark F.2s were converted to F.2As.

 

The F.3, with more powerful engines and the new Red Top missile was expected to be the definitive Skyspark, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. However, the F.3 also had only a short operational life and was withdrawn from service early due to defence cutbacks and the introduction of the even more capable and longer-range F.6, some of which were converted F.3s.

 

The introduction of the F.3 and F.6 allowed the RAF to progressively reequip squadrons operating aircraft such as the subsonic Gloster Javelin and retire these types during the mid-1960s. During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Skyspark's range and firepower shortcomings became increasingly apparent. The transfer of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force, alongside those withdrawn from Germany as they were replaced by SEPECAT Jaguars in the ground attack role.

The Skyspark's direct replacement was the Tornado F.3, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Skyspark, including far larger weapons load and considerably more advanced avionics. Skysparks were slowly phased out of service between 1974 and 1988, even though they lasted longer than expected because the definitive Tornado F.3 went through serious teething troubles and its service introduction was delayed several times. In their final years, the Skysparks’ airframes required considerable maintenance to keep them airworthy due to the sheer number of accumulated flight hours.

The kit and its assembly:

This build was a submission to the “Hunter, Lightning, Canberra” group build at whatifmodellers.com, and one of my personal ultimate challenges – a project that you think about very often, but the you put the thought back into its box when you realize that turning this idea into hardware will be a VERY tedious, complex and work-intensive task. But the thematic group build was the perfect occasion to eventually tackle the idea of a model of a “side-by-side engine BAC Lightning”, a.k.a. “Flatning”, as a rather conservative alternative to the real aircraft’s unique and unusual design with stacked engines in the fuselage, which brought a multitude of other design consequences that led to a really unique aircraft.

 

And it sound so simple: take a Lightning, just change the tail section. But it’s not that simple, because the whole fuselage shape would be different, resulting in less depth, the wings have to be attached somewhere and somehow, the landing gear might have to be adjusted/shortened, and how the fuselage diameter shape changes along the hull, so that you get a more or less smooth shape, was also totally uncertain!

 

Initially I considered a MiG Ye-152 as a body donor, but that was rejected due to the sheer price of the only available kit (ModelSvit). A Chinese Shenyang J-8I would also have been ideal – but there’s not 1:72 kit of this aircraft around, just of its successor with side intakes, a 1:72 J-8II from trumpeter.

I eventually decided to keep costs low, and I settled for the shaggy PM Model Su-15 (marketed as Su-21) “Flagon” as main body donor: it’s cheap, the engines have a good size for Avons and the pen nib fairing has a certain retro touch that goes well with the Lightning’s Fifties design.

The rest of this "Flatning" came from a Hasegawa 1:72 BAC Lightning F.6 (Revell re-boxing).

 

Massive modifications were necessary and lots of PSR. In an initial step the Flagon lost its lower wing halves, which are an integral part of the lower fuselage half. The cockpit section was cut away where the intake ducts begin. The Lightning had its belly tank removed (set aside for a potential later re-installation), and dry-fitting and crude measures suggested that only the cockpit section from the Lightning, its spine and the separate fin would make it onto the new fuselage.

 

Integrating the parts was tough, though! The problem that caused the biggest headaches: how to create a "smooth" fuselage from the Lightning's rounded front end with a single nose intake that originally develops into a narrow, vertical hull, combined with the boxy and rather wide Flagon fuselage with large Phantom-esque intakes? My solution: taking out deep wedges from all (rather massive) hull parts along the intake ducts, bend the leftover side walls inwards and glue them into place, so that the width becomes equal with the Lightning's cockpit section. VERY crude and massive body work!

 

However, the Lightning's cockpit section for the following hull with stacked engines is much deeper than the Flagon's side-by-side layout. My initial idea was to place the cockpit section higher, but I would have had to transplant a part of the Lightning's upper fuselage (with the spine on top, too!) onto the "flat" Flagon’s back. But this would have looked VERY weird, and I'd have had to bridge the round ventral shape of the Lightning into the boxy Flagon underside, too. This was no viable option, so that the cockpit section had to be further modified; I cut away the whole ventral cockpit section, at the height of the lower intake lip. Similar to my former Austrian Hasegawa Lightning, I also cut away the vertical bulkhead directly behind the intake opening - even though I did not improve the cockpit with a better tub with side consoles. At the back end, the Flagon's jet exhausts were opened and received afterburner dummies inside as a cosmetic upgrade.

 

Massive PSR work followed all around the hull. The now-open area under the cockpit was filled with lead beads to keep the front wheel down, and I implanted a landing gear well (IIRC, it's from an Xtrakit Swift). With the fuselage literally taking shape, the wings were glued together and the locator holes for the overwing tanks filled, because they would not be mounted.

 

To mount the wings to the new hull, crude measurements suggested that wedges had to be cut away from the Lightning's wing roots to match the weird fuselage shape. They were then glued to the shoulders, right behind the cockpit due to the reduced fuselage depth. At this stage, the Lightning’s stabilizer attachment points were transplanted, so that they end up in a similar low position on the rounded Su-15 tail. Again, lots of PSR…

 

At this stage I contemplated the next essential step: belly tank or not? The “Flatning” would have worked without it, but its profile would look rather un-Lightning-ish and rather “flat”. On the other side, a conformal tank would probably look quite strange on the new wide and flat ventral fuselage...? Only experiments could yield an answer, so I glued together the leftover belly bulge parts from the Hasegawa kit and played around with it. I considered a new, wider belly tank, but I guess that this would have looked too ugly. I eventually settled upon the narrow F.6 tank and also used the section behind it with the arrestor hook. I just reduced its depth by ~2 mm, with a slight slope towards the rear because I felt (righteously) that the higher wing position would lower the model’s stance. More massive PSR followed….

 

Due to the expected poor ground clearance, the Lightning’s stabilizing ventral fins were mounted directly under the fuselage edges rather than on the belly tank. Missile pylons for Red Tops were mounted to the lower front fuselage, similar to the real arrangement, and cable fairings, scratched from styrene profiles, were added to the lower flanks, stretching the hull optically and giving more structure to the hull.

 

To my surprise, I did not have to shorten the landing gear’s main legs! The wings ended up a little higher on the fuselage than on the original Lightning, and the front wheel sits a bit further back and deeper inside of its donor well, too, so that the fuselage comes probably 2 mm closer to the ground than an OOB Lightning model. Just like on the real aircraft, ground clearance is marginal, but when the main wheels were finally in place, the model turned out to have a low but proper stance, a little F8U-ish.

  

Painting and markings:

I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.

A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.

 

After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.

 

Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.

  

A major effort, and I have seriously depleted my putty stocks for this build! However, the result looks less spectacular than it actually is: changing a Lightning from its literally original stacked engine layout into a more conservative side-by-side arrangement turned out to be possible, even though the outcome is not really pretty. But it works and is feasible!

Some background:

The English Electric Skyspark was a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2. The Skyspark was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Skyspark.

 

The specification for the aircraft followed the cancellation of the Air Ministry's 1942 E.24/43 supersonic research aircraft specification which had resulted in the Miles M.52 program. W.E.W. "Teddy" Petter, formerly chief designer at Westland Aircraft, was a keen early proponent of Britain's need to develop a supersonic fighter aircraft. In 1947, Petter approached the Ministry of Supply (MoS) with his proposal, and in response Specification ER.103 was issued for a single research aircraft, which was to be capable of flight at Mach 1.5 (1,593 km/h) and 50,000 ft (15,000 m).

 

Petter initiated a design proposal with F W "Freddie" Page leading the design and Ray Creasey responsible for the aerodynamics. As it was designed for Mach 1.5, it had a 40° swept wing to keep the leading edge clear of the Mach cone. To mount enough power into the airframe, two engines were installed, in an unusual, stacked layout and with a high tailplane This proposal was submitted in November 1948, and in January 1949 the project was designated P.1 by English Electric. On 29 March 1949 MoS granted approval to start the detailed design, develop wind tunnel models and build a full-size mock-up.

 

The design that had developed during 1948 evolved further during 1949 to further improve performance. To achieve Mach 2 the wing sweep was increased to 60° with the ailerons moved to the wingtips. In late 1949, low-speed wind tunnel tests showed that a vortex was generated by the wing which caused a large downwash on the initial high tailplane; this issue was solved by lowering the tail below the wing. Following the resignation of Petter, Page took over as design team leader for the P.1. In 1949, the Ministry of Supply had issued Specification F23/49, which expanded upon the scope of ER103 to include fighter-level manoeuvring. On 1 April 1950, English Electric received a contract for two flying airframes, as well as one static airframe, designated P.1.

 

The Royal Aircraft Establishment disagreed with Petter's choice of sweep angle (60 degrees) and the stacked engine layout, as well as the low tailplane position, was considered to be dangerous, too. To assess the effects of wing sweep and tailplane position on the stability and control of Petter's design Short Brothers were issued a contract, by the Ministry of Supply, to produce the Short SB.5 in mid-1950. This was a low-speed research aircraft that could test sweep angles from 50 to 69 degrees and tailplane positions high or low. Testing with the wings and tail set to the P.1 configuration started in January 1954 and confirmed this combination as the correct one. The proposed 60-degree wing sweep was retained, but the stacked engines had to give way to a more conventional configuration with two engines placed side-by-side in the tail, but still breathing through a mutual nose air intake.

 

From 1953 onward, the first three prototype aircraft were hand-built at Samlesbury. These aircraft had been assigned the aircraft serials WG760, WG763, and WG765 (the structural test airframe). The prototypes were powered by un-reheated Armstrong Siddeley Sapphire turbojets, as the selected Rolls-Royce Avon engines had fallen behind schedule due to their own development problems. Since there was not much space in the fuselage for fuel, the thin wings became the primary fuel tanks and since they also provided space for the stowed main undercarriage the fuel capacity was relatively small, giving the prototypes an extremely limited endurance. The narrow tires housed in the thin wings rapidly wore out if there was any crosswind component during take-off or landing. Outwardly, the prototypes looked very much like the production series, but they were distinguished by the rounded-triangular air intake with no center-body at the nose, short fin, and lack of operational equipment.

 

On 9 June 1952, it was decided that there would be a second phase of prototypes built to develop the aircraft toward achieving Mach 2.0 (2,450 km/h); these were designated P.1B while the initial three prototypes were retroactively reclassified as P.1A. P.1B was a significant improvement on P.1A. While it was similar in aerodynamics, structure and control systems, it incorporated extensive alterations to the forward fuselage, reheated Rolls Royce Avon R24R engines, a conical center body inlet cone, variable nozzle reheat and provision for weapons systems integrated with the ADC and AI.23 radar. Three P.1B prototypes were built, assigned serials XA847, XA853 and XA856.

 

In May 1954, WG760 and its support equipment were moved to RAF Boscombe Down for pre-flight ground taxi trials; on the morning of 4 August 1954, WG760 flew for the first time from Boscombe Down. One week later, WG760 officially achieved supersonic flight for the first time, having exceeded the speed of sound during its third flight. While WG760 had proven the P.1 design to be viable, it was plagued by directional stability problems and a dismal performance: Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of just 48,000 ft (14,630 m), far below the requirements.

 

To solve the problem and save the P.1, Petter embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed a new, narrower canopy, a revised air intake, a pair of stabilizing fins under the rear fuselage, and a shallow ventral fairing at the wings’ trailing edge that not only reduced the drag coefficient along the wing/fuselage intersection, it also provided space for additional fuel.

On 4 April 1957 the modified P.1B (XA847) made the first flight, immediately exceeding Mach 1. During the early flight trials of the P.1B, speeds in excess of 1,000 mph were achieved daily.

In late October 1958, the plane was officially presented. The event was celebrated in traditional style in a hangar at Royal Aircraft Establishment (RAE) Farnborough, with the prototype XA847 having the name ‘Skyspark’ freshly painted on the nose in front of the RAF Roundel, which almost covered it. A bottle of champagne was put beside the nose on a special rig which allowed the bottle to safely be smashed against the side of the aircraft.

On 25 November 1958 the P.1B XA847 reached Mach 2 for the first time. This made it the second Western European aircraft to reach Mach 2, the first one being the French Dassault Mirage III just over a month earlier on 24 October 1958

 

The first operational Skyspark, designated Skyspark F.1, was designed as a pure interceptor to defend the V Force airfields in conjunction with the "last ditch" Bristol Bloodhound missiles located either at the bomber airfield, e.g. at RAF Marham, or at dedicated missile sites near to the airfield, e.g. at RAF Woodhall Spa near the Vulcan station RAF Coningsby. The bomber airfields, along with the dispersal airfields, would be the highest priority targets in the UK for enemy nuclear weapons. To best perform this intercept mission, emphasis was placed on rate-of-climb, acceleration, and speed, rather than range – originally a radius of operation of only 150 miles (240 km) from the V bomber airfields was specified – and endurance. Armament consisted of a pair of 30 mm ADEN cannon in front of the cockpit, and two pylons for IR-guided de Havilland Firestreak air-to-air missiles were added to the lower fuselage flanks. These hardpoints could, alternatively, carry pods with unguided 55 mm air-to-air rockets. The Ferranti AI.23 onboard radar provided missile guidance and ranging, as well as search and track functions.

 

The next two Skyspark variants, the Skyspark F.1A and F.2, incorporated relatively minor design changes, but for the next variant, the Skyspark F.3, they were more extensive: The F.3 had higher thrust Rolls-Royce Avon 301R engines, a larger squared-off fin that improved directional stability at high speed further and a strengthened inlet cone allowing a service clearance to Mach 2.0 (2,450 km/h; the F.1, F.1A and F.2 were all limited to Mach 1.7 (2,083 km/h). An upgraded A.I.23B radar and new, radar-guided Red Top missiles offered a forward hemisphere attack capability, even though additional electronics meant that the ADEN guns had to be deleted – but they were not popular in their position in front of the windscreen, because the muzzle flash blinded the pilot upon firing. The new engines and fin made the F.3 the highest performance Skyspark yet, but this came at a steep price: higher fuel consumption, resulting in even shorter range. From this basis, a conversion trainer with a side-by-side cockpit, the T.4, was created.

 

The next interceptor variant was already in development, but there was a need for an interim solution to partially address the F.3's shortcomings, the F.3A. The F.3A introduced two major improvements: a larger, non-jettisonable, 610-imperial-gallon (2,800 L) ventral fuel tank, resulting in a much deeper and longer belly fairing, and a new, kinked, conically cambered wing leading edge. The conically cambered wing improved manoeuvrability, especially at higher altitudes, and it offered space for a slightly larger leading edge fuel tank, raising the total usable internal fuel by 716 imperial gallons (3,260 L). The enlarged ventral tank not only nearly doubled available fuel, it also provided space at its front end for a re-instated pair of 30 mm ADEN cannon with 120 RPG. Alternatively, a retractable pack with unguided 55 mm air-to-air rockets could be installed, or a set of cameras for reconnaissance missions. The F.3A also introduced an improved A.I.23B radar and the new IR-guided Red Top missile, which was much faster and had greater range and manoeuvrability than the Firestreak. Its improved infrared seeker enabled a wider range of engagement angles and offered a forward hemisphere attack capability that would allow the Skyspark to attack even faster bombers (like the new, supersonic Tupolev T-22 Blinder) through a collision-course approach.

Wings and the new belly tank were also immediately incorporated in a second trainer variant, the T.5.

 

The ultimate variant, the Skyspark F.6, was nearly identical to the F.3A, with the exception that it could carry two additional 260-imperial-gallon (1,200 L) ferry tanks on pylons over the wings. These tanks were jettisonable in an emergency and gave the F.6 a substantially improved deployment capability, even though their supersonic drag was so high that the extra fuel would only marginally raise the aircraft’s range when flying beyond the sound barrier for extended periods.

 

Finally, there was the Skyspark F.2A; it was an early production F.2 upgraded with the new cambered wing, the squared fin, and the 610 imperial gallons (2,800 L) ventral tank. However, the F.2A retained the old AI.23 radar, the IR-guided Firestreak missile and the earlier Avon 211R engines. Although the F.2A lacked the thrust of the later Skysparks, it had the longest tactical range of all variants, and was used for low-altitude interception over West Germany.

 

The first Skysparks to enter service with the RAF, three pre-production P.1Bs, arrived at RAF Coltishall in Norfolk on 23 December 1959, joining the Air Fighting Development Squadron (AFDS) of the Central Fighter Establishment, where they were used to clear the Skyspark for entry into service. The production Skyspark F.1 entered service with the AFDS in May 1960, allowing the unit to take part in the air defence exercise "Yeoman" later that month. The Skyspark F.1 entered frontline squadron service with 74 Squadron at Coltishall from 11 July 1960. This made the Skyspark the second Western European-built combat aircraft with true supersonic capability to enter service and the second fully supersonic aircraft to be deployed in Western Europe (the first one in both categories being the Swedish Saab 35 Draken on 8 March 1960 four months earlier).

 

The aircraft's radar and missiles proved to be effective, and pilots reported that the Skyspark was easy to fly. However, in the first few months of operation the aircraft's serviceability was extremely poor. This was due to the complexity of the aircraft systems and shortages of spares and ground support equipment. Even when the Skyspark was not grounded by technical faults, the RAF initially struggled to get more than 20 flying hours per aircraft per month compared with the 40 flying hours that English Electric believed could be achieved with proper support. In spite of these concerns, within six months of the Skyspark entering service, 74 Squadron was able to achieve 100 flying hours per aircraft.

 

Deliveries of the slightly improved Skyspark F.1A, with revised avionics and provision for an air-to-air refueling probe, allowed two more squadrons, 56 and 111 Squadron, both based at RAF Wattisham, to convert to the Skyspark in 1960–1961. The Skyspark F.1 was only ordered in limited numbers and served only for a short time; nonetheless, it was viewed as a significant step forward in Britain's air defence capabilities. Following their replacement from frontline duties by the introduction of successively improved Skyspark variants, the remaining F.1 aircraft were employed by the Skyspark Conversion Squadron.

The improved F.2 entered service with 19 Squadron at the end of 1962 and 92 Squadron in early 1963. Conversion of these two squadrons was aided by the of the two-seat T.4 and T.5 trainers (based on the F.3 and F.3A/F.6 fighters), which entered service with the Skyspark Conversion Squadron (later renamed 226 Operational Conversion Unit) in June 1962. While the OCU was the major user of the two-seater, small numbers were also allocated to the front-line fighter squadrons. More F.2s were produced than there were available squadron slots, so later production aircraft were stored for years before being used operationally; some of these Skyspark F.2s were converted to F.2As.

 

The F.3, with more powerful engines and the new Red Top missile was expected to be the definitive Skyspark, and at one time it was planned to equip ten squadrons, with the remaining two squadrons retaining the F.2. However, the F.3 also had only a short operational life and was withdrawn from service early due to defence cutbacks and the introduction of the even more capable and longer-range F.6, some of which were converted F.3s.

 

The introduction of the F.3 and F.6 allowed the RAF to progressively reequip squadrons operating aircraft such as the subsonic Gloster Javelin and retire these types during the mid-1960s. During the 1960s, as strategic awareness increased and a multitude of alternative fighter designs were developed by Warsaw Pact and NATO members, the Skyspark's range and firepower shortcomings became increasingly apparent. The transfer of McDonnell Douglas F-4 Phantom IIs from Royal Navy service enabled these much longer-ranged aircraft to be added to the RAF's interceptor force, alongside those withdrawn from Germany as they were replaced by SEPECAT Jaguars in the ground attack role.

The Skyspark's direct replacement was the Tornado F.3, an interceptor variant of the Panavia Tornado. The Tornado featured several advantages over the Skyspark, including far larger weapons load and considerably more advanced avionics. Skysparks were slowly phased out of service between 1974 and 1988, even though they lasted longer than expected because the definitive Tornado F.3 went through serious teething troubles and its service introduction was delayed several times. In their final years, the Skysparks’ airframes required considerable maintenance to keep them airworthy due to the sheer number of accumulated flight hours.

The kit and its assembly:

This build was a submission to the “Hunter, Lightning, Canberra” group build at whatifmodellers.com, and one of my personal ultimate challenges – a project that you think about very often, but the you put the thought back into its box when you realize that turning this idea into hardware will be a VERY tedious, complex and work-intensive task. But the thematic group build was the perfect occasion to eventually tackle the idea of a model of a “side-by-side engine BAC Lightning”, a.k.a. “Flatning”, as a rather conservative alternative to the real aircraft’s unique and unusual design with stacked engines in the fuselage, which brought a multitude of other design consequences that led to a really unique aircraft.

 

And it sound so simple: take a Lightning, just change the tail section. But it’s not that simple, because the whole fuselage shape would be different, resulting in less depth, the wings have to be attached somewhere and somehow, the landing gear might have to be adjusted/shortened, and how the fuselage diameter shape changes along the hull, so that you get a more or less smooth shape, was also totally uncertain!

 

Initially I considered a MiG Ye-152 as a body donor, but that was rejected due to the sheer price of the only available kit (ModelSvit). A Chinese Shenyang J-8I would also have been ideal – but there’s not 1:72 kit of this aircraft around, just of its successor with side intakes, a 1:72 J-8II from trumpeter.

I eventually decided to keep costs low, and I settled for the shaggy PM Model Su-15 (marketed as Su-21) “Flagon” as main body donor: it’s cheap, the engines have a good size for Avons and the pen nib fairing has a certain retro touch that goes well with the Lightning’s Fifties design.

The rest of this "Flatning" came from a Hasegawa 1:72 BAC Lightning F.6 (Revell re-boxing).

 

Massive modifications were necessary and lots of PSR. In an initial step the Flagon lost its lower wing halves, which are an integral part of the lower fuselage half. The cockpit section was cut away where the intake ducts begin. The Lightning had its belly tank removed (set aside for a potential later re-installation), and dry-fitting and crude measures suggested that only the cockpit section from the Lightning, its spine and the separate fin would make it onto the new fuselage.

 

Integrating the parts was tough, though! The problem that caused the biggest headaches: how to create a "smooth" fuselage from the Lightning's rounded front end with a single nose intake that originally develops into a narrow, vertical hull, combined with the boxy and rather wide Flagon fuselage with large Phantom-esque intakes? My solution: taking out deep wedges from all (rather massive) hull parts along the intake ducts, bend the leftover side walls inwards and glue them into place, so that the width becomes equal with the Lightning's cockpit section. VERY crude and massive body work!

 

However, the Lightning's cockpit section for the following hull with stacked engines is much deeper than the Flagon's side-by-side layout. My initial idea was to place the cockpit section higher, but I would have had to transplant a part of the Lightning's upper fuselage (with the spine on top, too!) onto the "flat" Flagon’s back. But this would have looked VERY weird, and I'd have had to bridge the round ventral shape of the Lightning into the boxy Flagon underside, too. This was no viable option, so that the cockpit section had to be further modified; I cut away the whole ventral cockpit section, at the height of the lower intake lip. Similar to my former Austrian Hasegawa Lightning, I also cut away the vertical bulkhead directly behind the intake opening - even though I did not improve the cockpit with a better tub with side consoles. At the back end, the Flagon's jet exhausts were opened and received afterburner dummies inside as a cosmetic upgrade.

 

Massive PSR work followed all around the hull. The now-open area under the cockpit was filled with lead beads to keep the front wheel down, and I implanted a landing gear well (IIRC, it's from an Xtrakit Swift). With the fuselage literally taking shape, the wings were glued together and the locator holes for the overwing tanks filled, because they would not be mounted.

 

To mount the wings to the new hull, crude measurements suggested that wedges had to be cut away from the Lightning's wing roots to match the weird fuselage shape. They were then glued to the shoulders, right behind the cockpit due to the reduced fuselage depth. At this stage, the Lightning’s stabilizer attachment points were transplanted, so that they end up in a similar low position on the rounded Su-15 tail. Again, lots of PSR…

 

At this stage I contemplated the next essential step: belly tank or not? The “Flatning” would have worked without it, but its profile would look rather un-Lightning-ish and rather “flat”. On the other side, a conformal tank would probably look quite strange on the new wide and flat ventral fuselage...? Only experiments could yield an answer, so I glued together the leftover belly bulge parts from the Hasegawa kit and played around with it. I considered a new, wider belly tank, but I guess that this would have looked too ugly. I eventually settled upon the narrow F.6 tank and also used the section behind it with the arrestor hook. I just reduced its depth by ~2 mm, with a slight slope towards the rear because I felt (righteously) that the higher wing position would lower the model’s stance. More massive PSR followed….

 

Due to the expected poor ground clearance, the Lightning’s stabilizing ventral fins were mounted directly under the fuselage edges rather than on the belly tank. Missile pylons for Red Tops were mounted to the lower front fuselage, similar to the real arrangement, and cable fairings, scratched from styrene profiles, were added to the lower flanks, stretching the hull optically and giving more structure to the hull.

 

To my surprise, I did not have to shorten the landing gear’s main legs! The wings ended up a little higher on the fuselage than on the original Lightning, and the front wheel sits a bit further back and deeper inside of its donor well, too, so that the fuselage comes probably 2 mm closer to the ground than an OOB Lightning model. Just like on the real aircraft, ground clearance is marginal, but when the main wheels were finally in place, the model turned out to have a low but proper stance, a little F8U-ish.

  

Painting and markings:

I was uncertain about the livery for a long time – I just had already settled upon an RAF aircraft. But the model would not receive a late low-viz scheme (the Levin, my mono-engine Lightning build already had one), and no NMF, either. I was torn between an RAF Germany all-green over NMF undersides livery, but eventually went for a pretty standard RAF livery in Dark Sea Grey/Dark Green over NMF undersides, with toned-down post-war roundels.

A factor that spoke in favor of this route was a complete set of markings for an RAF 11 Squadron Lightning F.6 in such a guise on an Xtradecal set, which also featured dayglo orange makings on fin, wings and stabilizers – quite unusual, and a nice contrast detail on the otherwise very conservative livery. All stencils were taken from the OOB Revell sheet for the Lightning. Just the tactical code “F” on the tail was procured elsewhere, it comes from a Matchbox BAC Lightning’s sheet.

 

After basic painting the model received the usual black ink washing, some post-panel-shading and also a light treatment with graphite to create soot strains around the jet exhausts and the gun ports, and to emphasize the raised panel lines on the Hasegawa parts.

 

Finally, the model was sealed with matt acrylic varnish and final bits and pieces like the landing gear and the Red Tops (taken OOB) were mounted.

  

A major effort, and I have seriously depleted my putty stocks for this build! However, the result looks less spectacular than it actually is: changing a Lightning from its literally original stacked engine layout into a more conservative side-by-side arrangement turned out to be possible, even though the outcome is not really pretty. But it works and is feasible!

Some background:

The Bell XP-68A owed its existence to the manufacturer’s rather disappointing outcome of its first jet fighter design, the XP-59A Airacomet. The Airacomet was a twin jet-engined fighter aircraft, designed and built during World War II after Major General Henry H. "Hap" Arnold became aware of the United Kingdom's jet program when he attended a demonstration of the Gloster E.28/39 in April 1941. He requested, and was given, the plans for the aircraft's powerplant, the Power Jets W.1, which he took back to the U.S. He also arranged for an example of the engine, the Whittle W.1X turbojet, to be flown to the U.S., along with drawings for the more powerful W.2B/23 engine and a small team of Power Jets engineers. On 4 September 1941, he offered the U.S. company General Electric a contract to produce an American version of the engine, which subsequently became the General Electric I-A. On the following day, he approached Lawrence Dale Bell, head of Bell Aircraft Corporation, to build a fighter to utilize it. As a disinformation tactic, the USAAF gave the project the designation "P-59A", to suggest it was a development of the unrelated, canceled Bell XP-59 fighter project. The P-59A was the first design fighter to have its turbojet engine and air inlet nacelles integrated within the main fuselage. The jet aircraft’s design was finalized on 9 January 1942 and the first prototype flew in October of the same year.

 

The following 13 service test YP-59As had a more powerful engine than their predecessor, the General Electric J31, but the improvement in performance was negligible, with top speed increased by only 5 mph and a slight reduction in the time they could be used before an overhaul was needed. One of these aircraft, the third YP-59A, was supplied to the Royal Air Force, in exchange for the first production Gloster Meteor I for evaluation and flight-offs with domestic alternatives.

British pilots found that the YP-59A compared very unfavorably with the jets that they were already flying. The United States Army Air Forces were not impressed by its performance either and cancelled the contract when fewer than half of the originally ordered aircraft had been produced. No P-59s entered combat, but the type paved the way for the next design generation of U.S. turbojet-powered aircraft and helped to develop appropriate maintenance structures and procedures.

 

In the meantime, a new, more powerful jet engine had been developed in Great Britain, the Halford H-1, which became later better known as the De Havilland Goblin. It was another centrifugal compressor design, but it produced almost twice as much thrust as the XP-59A’s J31 engines. Impressed by the British Gloster Meteor during the USAAF tests at Muroc Dry Lake - performance-wise as well as by the aircraft’s simplicity and ruggedness - Bell reacted promptly and proposed an alternative fighter with wing-mounted engine nacelles, since the XP-59A’s layout had proven to be aerodynamically sub-optimal and unsuited for the installation of H-1 engines. In order to save development time and because the aircraft was rather regarded as a proof-of-concept demonstrator instead of a true fighter prototype, the new aircraft was structurally based on Bell’s current piston-engine P-63 “Kingcobra”. The proposal was accepted and, in order to maintain secrecy, the new jet aircraft inherited once more a designation of a recently cancelled project, this time from the Vultee XP-68 “Tornado” fighter. Similar to the Airacomet two years before, just a simple “A” suffix was added.

 

Bell’s development contract covered only three XP-68A aircraft. The H-1 units were directly imported from Great Britain in secrecy, suspended in the bomb bays of B-24 Liberator bombers. A pair of these engines was mounted in mid-wing nacelles, very similar to the Gloster Meteor’s arrangement. The tailplane was given a 5° dihedral to move it out of the engine exhaust. In order to bear the new engines and their power, the wing main spars were strengthened and the main landing gear wells were moved towards the aircraft’s centerline, effectively narrowing track width. The landing gear wells now occupied the space of the former radiator ducts for the P-63’s omitted Allison V-1710 liquid-cooled V12 engine. Its former compartment behind the cockpit was used for a new fuel tank and test equipment. Having lost the propeller and its long drive shaft, the nose section was also redesigned: the front fuselage became deeper and the additional space there was used for another fuel tank in front of the cockpit and a bigger weapon bay. Different armament arrangements were envisioned, one of each was to be tested on the three prototypes: one machine would be armed with six 0.5” machine guns, another with four 20mm Hispano M2 cannon, and the third with two 37mm M10 cannon and two 0.5” machine guns. Provisions for a ventral hardpoint for a single drop tank or a 1.000 lb (550 kg) bomb were made, but this was never fitted on any of the prototypes. Additional hardpoints under the outer wings for smaller bombs or unguided missiles followed the same fate.

 

The three XP-68As were built at Bell’s Atlanta plant in the course of early 1944 and semi-officially christened “Airagator”. After their clandestine transfer to Muroc Dry Lake for flight tests and evaluations, the machines were quickly nicknamed “Barrelcobra” by the test staff – not only because of the characteristic shape of the engine nacelles, but also due to the sheer weight of the machines and their resulting sluggish handling on the ground and in the air. “Cadillac” was another nickname, due to the very soft acceleration through the new jet engines and the lack of vibrations that were typical for piston-engine- and propeller-driven aircraft.

 

Due to the structural reinforcements and modifications, the XP-68A had become a heavy aircraft with an empty weight of 4 tons and a MTOW of almost 8 tons – the same as the big P-47 Thunderbolt piston fighter, while the P-63 had an MTOW of only 10,700 lb (4,900 kg). The result was, among other flaws, a very long take-off distance, especially in the hot desert climate of the Mojave Desert (which precluded any external ordnance) and an inherent unwillingness to change direction, its turning radius was immense. More than once the brakes overheated during landing, so that extra water cooling for the main landing gear was retrofitted.

Once in the air, the aircraft proved to be quite fast – as long as it was flying in a straight line, though. Only the roll characteristics were acceptable, but flying the XP-68A remained hazardous, esp. after the loss of one of the H-1s engines: This resulted in heavily asymmetrical propulsion, making the XP-68A hard to control at all and prone to spin in level flight.

 

After trials and direct comparison, the XP-68A turned out not to be as fast and, even worse, much less agile than the Meteor Mk III (the RAF’s then current, operational fighter version), which even had weaker Derwent engines. The operational range was insufficient, too, esp. in regard of the planned Pacific theatre of operations, and the high overall weight precluded any considerable external load like drop tanks.

However, compared with the XP-59A, the XP-68A was a considerable step forward, but it had become quickly clear that the XP-68A and its outfit-a-propeller-design-with jet-engines approach did not bear the potential for any service fighter development: it was already outdated when the prototypes were starting their test program. No further XP-68A was ordered or built, and the three prototypes fulfilled their test and evaluation program until May 1945. During these tests, the first prototype was lost on the ground due to an engine fire. After the program’s completion, the two remaining machines were handed over to the US Navy and used for research at the NATC Patuxent River Test Centre, where they were operated until 1949 and finally scrapped.

The kit and its assembly:

This whiffy Kingcobra conversion was spawned by a post by fellow user nighthunter in January 2019 at whatifmodelers.com about a potential jet-powered variant. In found the idea charming, since the XP-59 had turned out to be a dud and the Gloster Meteor had been tested by the USAAF. Why not combine both into a fictional, late WWII Bell prototype?

The basic idea was simple: take a P-63 and add a Meteor’s engine nacelles, while keeping the Kingcobra’s original proportions. This sounds pretty easy but was more challenging than the first look at the outcome might suggest.

 

The donor kits are a vintage Airfix 1:72 Gloster Meteor Mk.III, since it has the proper, small nacelles, and an Eastern Express P-63 Kingcobra. The latter looked promising, since this kit comes with very good surface and cockpit details (even with a clear dashboard) as well as parts for several P-63 variants, including the A, C and even the exotic “pinball” manned target version. However, anything comes at a price, and the kit’s low price point is compensated by soft plastic (which turned out to be hard to sand), some flash and mediocre fit of any of the major components like fuselage halves, the wings or the clear parts. It feels a lot like a typical short-run kit. Nevertheless, I feel inclined to build another one in a more conventional fashion some day.

 

Work started with the H-1 nacelles, which had to be cut out from the Meteor wings. Since they come OOB only with a well-visible vertical plate and a main wing spar dummy in the air intake, I added some fine mesh to the plate – normally, you can see directly onto the engine behind the wing spar. Another issue was the fact that the Meteor’s wings are much thicker and deeper than the P-63s, so that lots of PSR work was necessary.

 

Simply cutting the P-63 OOB wings up and inserting the Meteor nacelles was also not possible: the P-63 has a very wide main landing gear, due to the ventral radiators and oil coolers, which were originally buried in the wing roots and under the piston engine. The only solution: move the complete landing gear (including the wells) inward, so that the nacelles could be placed as close as possible to the fuselage in a mid-span position. Furthermore, the - now useless - radiator openings had to disappear, resulting in a major redesign of the wing root sections. All of this became a major surgery task, followed by similarly messy work on the outer wings during the integration of the Meteor nacelles. LOTS of PSR, even though the outcome looks surprisingly plausible and balanced.

 

Work on the fuselage started in parallel. It was built mainly OOB, using the optional ventral fin for a P-63C. The exhaust stubs as well as the dorsal carburetor intake had to disappear (the latter made easy thanks to suitable optional parts for the manned target version). Since the P-63 had a conventional low stabilizer arrangement (unlike the Meteor with its cruciform tail), I gave them a slight dihedral to move them out of the engine efflux, a trick Sukhoi engineers did on the Su-11 prototype with afterburner engines in 1947, too.

 

Furthermore, the whole nose ahead of the cockpit was heavily re-designed, because I wanted the “new” aircraft to lose its propeller heritage and the P-63’s round and rather pointed nose. Somewhat inspired by the P-59 and the P-80, I omitted the propeller parts altogether and re-sculpted the nose with 2C putty, creating a deeper shape with a tall, oval diameter, so that the lower fuselage line was horizontally extended forward. In a profile view the aircraft now looks much more massive and P-80esque. The front landing gear was retained, just its side walls were extended downwards with the help of 0.5mm styrene sheet material, so that the original stance could be kept. Lots of lead in the nose ensured that the model would properly stand on its three wheels.

 

Once the rhinoplasty was done I drilled four holes into the nose and used hollow steel needles as gun barrels, with a look reminiscent of the Douglas A-20G.

Adding the (perfectly) clear parts of the canopy as a final assembly step also turned out to be a major fight against the elements.

  

Painting and markings:

With an USAAF WWII prototype in mind, there were only two options: either an NMF machine, or a camouflage in Olive Drab and Neutral Grey. I went for the latter and used Tamiya XF-62 for the upper surfaces and Humbrol 156 (Dark Camouflage Grey) underneath. The kit received a light black ink wash and some post shading in order to emphasize panels. A little dry-brushing with silver around the leading edges and the cockpit was done, too.

 

The cockpit interior became chromate green (I used Humbrol 150, Forest Green) while the landing gear wells were painted with zinc chromate yellow (Humbrol 81). The landing gear itself was painted in aluminum (Humbrol 56).

Markings/decals became minimal, puzzled together from various sources – only some “Stars and Bars” insignia and the serial number.

  

Somehow this conversion ended up looking a lot like the contemporary Soviet Sukhoi Su-9 and -11 (Samolyet K and LK) jet fighter prototype – unintentionally, though. But I am happy with the outcome – the P-63 ancestry is there, and the Meteor engines are recognizable, too. But everything blends into each other well, the whole affair looks very balanced and believable. This is IMHO furthermore emphasized by the simple paint scheme. A jet-powered Kingcobra? Why not…?

Some background:

The Leyland “Type D” was one of several armoured vehicle types designed in 1940 on the orders of Lord Beaverbrook and Admiral Sir Edward Evans, as a part of the hasty measures taken by the British Government following the Dunkirk evacuation and the threat of invasion.

The “Type D” was a heavy scout car, intended to replace the Lanchester 6x4 and Rolls-Royce 4x2 armoured cars, which dated back to the WWI era and the early interwar period. While they were reliable vehicles and still in active service, their off-road capabilities, armament and armour left a lot to be desired – esp. in the face of the modern German army and its effective equipment.

 

Certainly inspired by the German SdKfz. 231/232 family of heavy 8x8 armoured reconnaissance vehicles, Leyland added a fourth axle to better distribute the vehicle’s weight and a drivetrain to the front axle to a modified “Retriever” 3-ton 6x4 lorry chassis, resulting in a 6x8 layout. The rigid axles were mounted on leaf springs front and rear with hydraulic dampers, both front axles were steerable. The engine, a water-cooled 6-litre, 4-cylinder overhead camshaft petrol engine with 73 hp, was, together with the gearbox, relocated to the rear, making room for a fully enclosed crew compartment in the front section with two access doors in the vehicle’s flanks. The crew consisted of four, with the driver seat at the front. The gunner and commander (the commander at the right and gunner at the left) stood behind them into the turret or were sitting on simple leather belts, and behind them was a working station for a radio operator.

 

The tall, cylindrical turret was welded and electrically traversed, but it lacked a commander cupola. All the armament was mounted in the turret and consisted of a quick-firing two-pounder (40mm) cannon and a coaxial 7.92 mm Besa machine gun. The faceted hull was, like the turret, welded from homogenous steel armour plates, and a straightforward design. Maximum armour thickness was 15 mm at the front, 8 mm on the sides, and 10 mm on the back, with 6 mm and 5 mm of armour on the top and bottom respectively. It had been designed to provide protection from small arms fire and HE fragments, but it was ineffective against heavier weapons. This armour was a compromise, since better protection had resulted in a higher weight and overstrained the Type D’s lorry chassis and engine. The armoured cabin was mounted to the chassis at only four points - front, rear and sides - to give some flexibility but with precautions against excessive movement.

 

The Type D’s prototype was designed, built, tested and approved just within 3 months. Deliveries of the first production vehicles commenced only 2 months later, just in time to become involved in the North Africa campaign. All early production vehicles were immediately sent to Egypt and took part in Operation Compass and the Western Desert Campaign.

It comes as no surprise that the Type D – developed and produced in a hurry and thrown into battle in an environment it had not been designed for – initially failed, and even when the worst deficits had been rectified the Type D’s performance remained mediocre at best. The biggest problems concerned the engine’s cooling system, its low power output and therefore poor speed, and the vehicle’s poor off-road performance, esp. on soft ground like sand. The vehicle’s suspension was quickly overburdened in heavy terrain and the tall turret placed its center of gravity very high, making the Type D prone to topple over to a side when slope angles were taken too slightly. Poor cabin ventilation was another problem that became even more apparent under the African sun.

 

Initial losses were high: more than half of the Type Ds lost in North Africa during the early months of 1941 were abandoned vehicles which got stuck or had to be left behind due to mechanical failures. The rest had fallen easy prey to German and Italian attacks – the Type D was not only very vulnerable even to the Panzer II’s 20 mm autocannon, its thin top armour made it in the open desert also very vulnerable to air attacks: German MG 131 machine gun rounds easily punched the vehicle’s shell, and even lighter weapons were a serious threat to the tall Type D.

 

As soon as the first sobering field reports returned back to Great Britain, Leyland immediately devised major improvements. These were introduced to newly produced Mk. II vehicles and partly retrofitted to the early Mk. I vehicles in field workshops. One of these general improvements were new desert wheels and tires, which were considerably wider than the original lorry wheels and featured a flat pattern that better distributed the vehicle’s weight on soft and unstable ground, what considerably improved the Type D’s performance on sand. A kit with a more effective radiator and a bigger engine cooling system was quickly developed and sent to the units in Africa, too. The kit did not fully solve the overheating problems of the early Mk. I, but improved the situation. From the outside, retrofitted Type Ds could be recognized by a raised engine cover with enlarged air intakes. Due to the limits of the chassis the armour level was not improved, even though the crews and field workshops tried to attach improvised additional protective measures like spare track links from tanks or sandbags – with mixed results, though. The armament was not updated either, except for an optional mount for an additional light anti-aircraft machine gun on the turret and kits for smoke dischargers on the turret’s flanks.

 

The Type D Mk. II, which gradually replaced the Mk. I on the production lines from March 1941 on, furthermore received a different and much more effective powerplant, a Leyland 7-litre six-cylinder diesel engine with an output of 95 hp (70 kW). It not only provided more power and torque, markedly improving the vehicle’s off-road performance, it also had a better fuel economy than the former lorry petrol engine (extending range by 25%), and the fuel itself was less prone to ignite upon hits or accidents.

 

During its short career the Leyland Type D was primarily used in the North African Campaign by the 11th Hussars and other units. After the invasion of Italy, a small number was also used in the Southern European theatre by reconnaissance regiments of British and Canadian infantry divisions. A few vehicles were furthermore used for patrol duty along the Iran supply route.

However, the Type D was not popular, quickly replaced by smaller and more agile vehicles like the Humber scout car, and by 1944 outdated and retired. Leyland built a total of 220 Type Ds of both versions until early 1943, whilst an additional 86 Mk. IIs were built by the London, Midland and Scottish Railway's Derby Carriage Works.

The kit and its assembly:

This fictional British WWII vehicle might look weird, but it has a real-world inspiration: the Marmon Herrington Mk. VI armoured heavy scout car. This vehicle only existed as a prototype and is AFAIK still preserved in a museum in South Africa – and upon a cursory glance it looks like an SdKfz. 232 with the shrunk turret from a “Crusader” cruiser tank with a short-barreled six pounder gun. It looks like a fake! Another reason for this build was a credible “canvas” for the application of the iconic “Caunter Scheme”, so that I placed the Type D in a suitable historic time frame.

 

The Type D was not supposed to be a truthful Marmon Herrington Mk. VI copy, so I started with a 1:72 “First to Fight” SdKfz. 232. This is a simple and sturdy tabletop wargaming model, but it is quite accurate, goes together well, is cheap and even comes with a metal gun barrel. It’s good value for the money, even though the plastic is a little thick and soft.

 

However, from this basis things changed in many ways. I initially wanted to shorten the hull, but the new wheels (see below) made this idea impossible. Nevertheless, the front glacis plate was completely re-modeled with 2C putty in the style of the Humber scout car, and the crew cabin was extended backwards with the same method. New observation slits had to be scratched with styrene profile material. The engine bay received a raised cover, simulating extra air intakes. The turret was replaced with a resin piece for an A13 “Valentine” Mk.III tank (S&S Models), which had a perfect size and even came with a suitable gun.

 

The suspension was taken OOB, but the wheels were replaced with two aftermarket resin sets (Silesian Models) with special Allied desert wheels/tires from 1941, they originally belong to a Chevrolet truck and are markedly bigger and wider than the SdKfz. 232 wheels. However, they had to be modified to match the rest of the suspension, and their size necessitated a thorough modification of the mudguards. They were not only mounted 1mm higher on the flanks, their sides, normally consisting of closed skirts, were fully opened to make sufficient room for the new wheels to change the vehicle’s look. They were furthermore separated into four two-wheel covers and their front and rear ends were slightly bent upwards. Sufficient space for the side doors had to be made, too. The spare wheels that came with the respective sets were mounted to the front (again Humber-style) and onto the engine bay cover, under a scratched tarpaulin (made from paper tissue drenched with white glue).

 

To conceal the SdKfz. 232 heritage even more I added more equipment to the vehicle’s flanks. Tool boxed were added to the engine bay’s flanks, some more tools to the fenders, scratched tarpaulin rolls above the side doors and I tried to scratch PSP plates with aluminum foil rubbed against a flight stand diorama floor made from PSP. Not perfect, but all the stuff livens the Type D up. A new exhaust (IIRC from a Panzer IV) was added to the rear and bumpers scratched from wire and mounted low unto the hull.

  

Painting and markings:

Finally, the British, so-called “Caunter Scheme”, a great source of misinterpretation not only in museums but also by modelers who have painted their British tanks in dubious if not garish colors. I do not claim that my interpretation of the colors is authentic, but I did some legwork and tried to improvise with my resources some tones that appear plausible (at least to me), based on descriptions and contemporary references.

 

The pattern itself was well defined for each vehicle type, and I adapted a M3 “Stuart” pattern for the model. All three basic colors, “Light Stone”, “Silver Grey” and “Slate”, were guesstimated. “Slate” is a relatively dark and greenish tone, and I chose Tamiya XF-65 (Field Grey). “Light Stone” is rather yellow-ish, light sand tone, and I used Humbrol 103 (Cream). Some sources suggest the use of Humbrol 74 (linen) as basis, but that is IMHO too yellow-ish and lacks red. The most obscure tone is “Silver Grey”, and its depictions range from a pale and dull light olive drab over blue-grey, greenish grey to bright light blue and even turquoise. In fact, this tone must have had a greenish-blue hue, and so I mixed Humbrol 145 (FS 35237) with maybe Humbrol 94 in a 3:1 ratio to achieve an “in between” tone, which is hard to describe - maybe as a greenish sand-grey? A funny effect of the colors in direct contrast is that the XF-65 appeared with an almost bluish hue! Overall, the choice of colors seems to work, though, and the impression is good.

 

Painting was, as usual, done with brushes and, due to the vehicle’s craggy shape, free-handedly. After basic painting the model received a light washing with a mix of black ink and brown, and some post-shading was done with light grey (Revell 75) and Hemp (Humbrol 168). Decals came from the scrap box, and before an overall protective coat of matt acrylic varnish was applied, the model received an additional treatment with thinned Revell 82 (supposed to be RAF Dark Earth but it is a much paler tone).

  

A more demanding build than one would expect at first sight. The SdKafz. 232 is unfortunately still visible, but the desert wheels, including the spare wheels, change the look considerably, and the British replacement turret works well, too. Using the tabletop model basis was not a good move, though, because everything is rather solid and somewhat blurry, esp. the many molded surface details, which suffered under the massive body work. On the other side, the Counter Scheme IMHO turned out well, esp. the colors, even though the slender hull made the adaptation of the pattern from a (much shorter) tank not easy. But most of the critical areas were hidden under extra equipment, anyway. 😉

 

+++ DISCLAIMER +++

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

  

Some background:

The Indian „Samudree Baaj“ (समुद्री बाज, Sea Hawk) was a highly modified, navalized version of the British BAE Systems Hawk land-based training jet aircraft, which had been manufactured under license by Hindustan Aeronautics Limited (HAL). The first indigenously built Hawk Mk. 132 trainer was delivered in 2008 to the Indian Air Force, and the type has since then been updated with indigenous avionics into the “Hawk-I” Mk. 132 from 2020 onwards. The aircraft’s Rolls Royce Adour Mk 871 engine was also license-built by HAL, and the company had experience from a wide range of aircraft projects in the past.

 

The Samudree Baaj project was initiated in 2006 by the Indian Navy, as part of the long historic plan to provide the Indian Navy with a fully capable aircraft carrier. This plan had been initiated in 1989, when India announced a plan to replace its ageing British-built aircraft carriers, INS Vikrant and INS Viraat (ex-HMS Hermes), with two new 28,000-ton Air Defence Ships (ADS) that would operate the BAe Sea Harrier aircraft. The first vessel was to replace Vikrant, which was set to decommission in early 1997. Construction of the ADS was to start at the Cochin Shipyard (CSL) in 1993 after the Indian Naval Design Organisation had translated this design study into a production model. Following the 1991 economic crisis, the plans for construction of the vessels were put on hold indefinitely.

 

In 1999, then-Defence Minister George Fernandes revived the project and sanctioned the construction of the Project “71 ADS”. By that time, given the ageing Sea Harrier fleet, the letter of intent called for a carrier that would carry more modern jet fighters. In 2001, CSL released a graphic illustration showing a 32,000-ton STOBAR (Short Take-Off But Arrested Recovery) design with a pronounced ski jump. The aircraft carrier project finally received formal government approval in January 2003. By then, design updates called for a 37,500-ton carrier to operate the MiG-29K. India opted for a three-carrier fleet consisting of one carrier battle group stationed on each seaboard, and a third carrier held in reserve, in order to continuously protect both its flanks, to protect economic interests and mercantile traffic, and to provide humanitarian platforms in times of disasters, since a carrier can provide a self-generating supply of fresh water, medical assistance or engineering expertise to populations in need for assistance.

 

In August 2006, then-Chief of the Naval Staff, Admiral Arun Prakash stated that the designation for the vessel had been changed from Air Defence Ship (ADS) to Indigenous Aircraft Carrier (IAC). The euphemistic ADS had been adopted in planning stages to ward off concerns about a naval build-up. Final revisions to the design increased the displacement of the carrier from 37,500 tons to over 40,000 tons. The length of the ship also increased from 252 metres (827 ft) to 262 metres (860 ft).

It was at this time that, beyond the MiG-29K, primarily a carrier-capable trainer and also a light (and less costly) strike aircraft would be needed. With the running production of the Hawk Mk. 132 for the Indian Air Force and BAE Systems’ connection and experience to the USA and McDonnell/Boeing’s adaptation of the Hawk as the US Navy’s carrier-capable T-45 trainer, HAL was instructed to develop a suitable aircraft family on the Hawk’s basis for the new carriers.

 

HAL’s Samudree Baaj is a fully carrier-capable version of the British Aerospace Hawk Mk. The Hawk had not originally been designed to perform carrier operations, so that numerous modifications were required, such as the extensive strengthening of the airframe to withstand the excessive forces imposed by the stresses involved in catapult launches and high sink-rate landings, both scenarios being routine in aircraft carrier operations.

 

The aerodynamic changes of the aircraft, which were mutually developed by HAL and BAE Systems, included improvements to the low-speed handling characteristics and a reduction in the approach speed. Most notable amongst the changes made to the Hawk's design were extended flaps for better low-speed handling, along with the addition of spoilers on the wings to reduce lift and strakes on the fuselage which improved airflow and stabilizer efficiency.

Other, less obvious modifications included a reinforced airframe, the adoption of a more robust and widened landing gear, complete with a catapult tow bar attachment to the oleo strut of the new two-wheel nose gear design, and an arresting hook. The tail fin was extended by 1 foot (12 in, 30.5 cm) to compensate for the loss of the Hawk’s ventral stabilizing strakes. To make room for the arrester hook, the original ventral air brake was split and re-located to the flanks, similar to the USN’s T-45 trainer.

 

At the time of the Samudree Baaj’s design, the exact catapult arrangement and capacity on board of India’s new carriers was not clear yet – even more so, since the MiG-29K and its powerful engines might have made a catapult obsolete. Therefore, the Samudree Baaj was designed to be operable either with a ski jump ramp (in the style of the Russian Kiev class carriers, of which India had purchased one as INS Vikramaditya) or with only minimal launch support within the projected STOBAR concept, which included a relatively short-stroke steam catapult and a similarly short, undampened arrester gear.

 

By 2009 the basic airframe had been defined and four prototypes were built for two versions: the Mk. 101 trainer, which was basically a navalized version of the land-based Mk. 132 with almost the same mission equipment, and the Mk. 201, a single-seater. Two airframes of each type were built and the first Samudree Baaj flight took place in early 2011. The Indian government ordered 30 trainers and 15 attack aircraft, to be delivered with the first new Indian carrier, INS Vikrant, in late 2017.

 

The Samudree Baaj Mk. 201 was developed from the basic navalized Hawk airframe as a light multirole fighter with a small visual signature and high maneuverability, but high combat efficiency and capable of both strike and point defense missions. It differed from the trainer through a completely new forward fuselage whereby the forward cockpit area, which normally housed the trainee, was replaced by an electronics bay for avionics and onboard systems, including a fire control computer, a LINS 300 ring laser gyroscope inertial navigation system and a lightweight (145 kg) multimode, coherent, pulse-Doppler I band airborne radar. This multimode radar was developed from the Ferranti Blue Fox radar and capable of airborne interception and air-to-surface strike roles over water and land, with look-down/shoot-down and look-up modes. It had ten air-to-surface and ten air-to-ground modes for navigation and weapon aiming purposes.

A ventral fairing behind the radome carried a laser rangefinder and a forward-looking infrared (FLIR). Mid-air refueling was also possible, through a detachable (but fixed) probe. GPS navigation or modern night-flight systems were integrated, too.

 

Like the trainer, the Mk. 201 had a total of seven weapon hardpoints (1 ventral, four underwing and a pair of wing tip launch rails), but the more sophisticated avionics suite allowed a wider range of ordnance to be carried and deployed, which included radar-guided AAMs for BVR strokes and smart weapons and guided missiles – especially the Sea Eagle and AGM-84 “Harpoon” anti-ship missiles in the Indian Navy’s arsenal. For the maritime strike role and as a support for ASW missions, the Samudree Baaj Mk. 201 could even deploy Sting Ray homing torpedoes.

Furthermore, a pair of 30mm (1.18 in) ADEN machine cannon with 150 RPG were housed in a shallow fairing under the cockpit. The self-protection systems include a BAE SkyGuardian 200 RWR and automatic Vinten chaff/flare dispensers located above the engine exhaust.

 

The Samudree Baaj project was highly ambitious, so that it does not wonder that there were many delays and teething troubles. Beyond the complex avionics integration this included the maritime adaptation of the Adour engine, which eventually led to the uprated Adour Mk. 871-1N, which, as a side benefit, also offered about 10% more power.

However, in parallel, INS Vikrant also ran into delays: In July 2012, The Times of India reported that construction of Vikrant has been delayed by three years, and the ship would be ready for commissioning by 2018. Later, in November 2012, Indian English-language news channel NDTV reported that cost of the aircraft carrier had increased, and the delivery has been delayed by at least five years and is expected to be with the Indian Navy only after 2018 as against the scheduled date of delivery of 2014. Work then commenced for the next stage of construction, which included the installation of the integrated propulsion system, the superstructure, the upper decks, the cabling, sensors and weapons. Vikrant was eventually undocked on 10 June 2015 after the completion of structural work. Cabling, piping, heat and ventilation works were to be completed by 2017; sea trials would begin thereafter. In December 2019, it was reported that the engines on board the ship were switched on and in November 2020, only the basin trials of the aircraft carrier were completed.

 

By that time, the first Samudree Baaj aircraft had been delivered to Indian Navy 300 squadron, and even though only based at land at Hansa Air Station, flight training and military operations commenced. In the meantime, the start of Vikrant's trials had initially been scheduled to begin on 12 March 2020, but further construction delays caused that to be moved back to April. With the COVID-19 crisis, the navy explained that trials were unlikely to begin before September/October. During the Navy Day press meeting in December 2019, Navy Chief Admiral Karambir Singh said Vikrant would be fully operational before the end of 2022. The COVID-19 pandemic had already pushed that back to 2023 and further delays appeared possible.

In late 2020, the Indian Navy expected to commission Vikrant by the end of 2021. Until then, the Samudree Baaj fleet will remain land-based at INS Hansa near Goa. This not only is the INAS 300 home base, it is also the location of the Indian Navy's Shore Based Test Facility (SBTF), which is a mock-up of the 283-metre (928 ft) INS Vikramaditya (a modified Kiev-class aircraft carrier) deck built to train and certify navy pilots, primarily the the Mikoyan MiG-29K for operating from the aircraft carrier, but now also for the Samudree Baaj and for the developmental trials of the naval HAL Tejas lightweight fighter.

The kit and its assembly:

A subtle kitbashing project, inspired by a CG-rendition of a carrier-based (yet un-navalized) BAe Hawk 200 in Indian Navy service by fellow user SPINNERS in January 2021. I found the idea inspiring but thought that the basic concept could be taken further and into hardware form with a model. And I had a Matchbox Hawk 200 in The Stash™, as well as a McDonnell T-45 trainer from Italeri…

 

The plan sounds simple: take a T-45 and replace the cockpit section with the single-seat cockpit from the Hawk 200. And while the necessary cuts were easy to make, reality rears its ugly head when you try to mate parts from basically the same aircraft but from models by different manufacturers.

 

The challenges started with the fact that the fuselage shapes of both models differ – the Matchbox kit is more “voluminous”, and the different canopy shape called for a partial spine transplant, which turned out to be of very different shape than the T-45’s respective section! Lots of PSR…

In order to improve the pretty basic Matchbox Hawk cockpit I integrated the cockpit tub from the Italeri T-45, including the ejection seat, dashboard and its top cover.

For the totally different T-45 front wheel I had to enlarge the respective well and added a “ceiling” to it, since the strut had to be attached somewhere. The Hawk 200’s ventral tub for the cannons (which only the first prototype carried, later production aircraft did not feature them) were retained – partly because of their “whiffy“ nature, but also because making it disappear would have involved more major surgeries.

Most of the are behind the cockpit comes from the Italeri T-45, I just added a RHAWS fairing to the fin, extending it by 3mm.

 

A major problem became the air intakes, because the two kits differ in their construction. I wanted to use the Italeri parts, because they match the fairings on the fuselage flanks well and are better detailed than the Matchbox parts. But the boundary layer spacers between intakes and fuselage are molded into the Italeri parts, while the Matchbox kit has them molded into the fuselage. This called for major surgery and eventually worked out fine, and more PSR blended the rest of the fuselage donors around the cockpit together. A tedious process, though.

 

The pylons were puzzled together, including a former Matchbox EA-6B wing pylon under the fuselage, cut down and mounted in reverse and upside down! The ordnance comes from the Italeri NATO weapons set (Matra Magic and AGM-84), the ventral drop tank comes IIRC from an Eduard L-39 Albatros. Matra Magics were chosen because India never operated any Sidewinder AAM, just French or Soviet/Russian missiles like the R-60 or R-73 (unlikely on the Hawk, IMHO), and I had preferred a pair of Sea Eagle ASMs (from a Hasegawa Sea Harrier kit), but their span turned out to be too large for the Hawk’s low wings. The alternative, more slender Harpoons are plausible, though, since they are actually part of the Indian Navy’s inventory.

  

Painting and markings:

The Indian Navy theme was already settled, and I wanted to stay close to SPINNERS’ illustration as well as to real world Indian Navy aircraft. SPINNERS’ Hawk carried the typical Sea Harreir scheme in Extra Dark Sea Grey and White, and I found this livery to look a bit too much retro, because I’d place this what-if aircraft in the early 2020s, when the Sea Harriers had already been phased out. A “realistic” livery might have been an overall mid-grey paint scheme (like the land-based Indian Hawk 132s), but I found this to look too boring. As a compromise, I gave the Samudree Baaj a simple two-tone paint scheme, carried by a few late Indian Sea Harriers. It consists of upper surfaces in Dark Sea Grey (Humbrol 164) and undersides in Medium Sea Grey (Modelmaster 2058), with a low waterline. The Modelmaster MSG has – for my taste – a rather bluish hue and appears almost like PRU Blue, but I left it that way.

 

The decals were puzzled together from variosu sources. the roundels come from a MiG-21F (Begemot), the unit markings and tactical codes from a Model Alliance Sea Harrier sheet, and the stencils are a mix from the Matchbox Hawk 200 and the Italeri T-45.

 

The kit was sealed with matt acrylic varnish from Italeri.

 

The fictional HAL „Samudree Baaj“ looks simple, but combining kits of the basically same aircraft from different manufacturers reveals their differences, and they are not to be underestimated! However, I like the result of a navalized Hawk single-seater, and - also with the relatively simple and dull livery - it looks pretty convincing.

Many thanks to SPINNERS for the creative inspiration - even though my build is not a 100% "copy" of the artwork, but rather a step further into the navalisation idea with the T-45 parts.

Some background:

The 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...

I used to call these two of my favorite kitbashs "Mr. & Mrs. Depression" but after attending a great lecture on depression and photography, I understand that depression is much more different and complex than just to be pictured by sadness alone.
