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

The kit and its assembly:

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

 

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

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

 

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

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

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

 

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

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

 

The ordnance came from various sources. The Sidewinders under the wing tips were taken from a Hasegawa USAF weapon set, representing the state-of-the-art of aerial defence. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-4 and -19 missile pods on the stub wings were taken from the OV-10 kit.

Some background:

The Nakajima Ki-104 was a further development of the Ki-87; the latter was a Japanese high-altitude fighter-interceptor of World War II, a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.

 

The Ki-87 was one of several designs of various manufacturers developed in response to American B-29 Superfortress raids on the Home Islands. The Ki-87 followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began.

 

The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the high-performance, tandem-engine Tachikawa Ki-94-I, while the Ki-87 under the lead of Kunihiro Aoki was developed as a fall-back project, using less stringent requirements.

Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945.

 

The Technical Division of Imperial Army Headquarters made itself felt during the development of the Ki-87 prototype when they insisted upon placing the turbo-supercharger in the rear-fuselage, and from the sixth prototype the Nakajima fighter was to have that arrangement. Construction was further delayed due to problems with the electrical undercarriage and the turbo-supercharger itself. As a consequence, the first Ki-87 prototype was not completed until February 1945; it first flew in April, but only five test flights were completed.

 

A further variant, the Ki-87-II, powered by a 3,000 hp Nakajima Ha217 (Ha-46) engine and with the turbo-supercharger in the same position as the P-47 Thunderbolt. Due to the long development period of the Ki-87, several major structural changes were made, too, that eventually changed the aircraft so much that it received a new, separate kitai number and became the Ki-104.

 

Kunihiro Aoki's new design was approved by the Koku Hombu, and an order was placed for one static test airframe, three prototypes, and eighteen pre-production aircraft. Only 2 prototypes were built in the event; the first was equipped with a single 1,895 kW (2,541 hp) Nakajima Ha219 [Ha-44] engine, driving a 4-blade, but the second one received the stronger Nakajima Ha217 (Ha-46) and a 6-blade propeller.

 

The pre-production machines (Ki-104-I or -Tei) were all produced with Ha217 engines, but featured various four-bladed propeller (-a, -b) designs as well as the new 6-blade propeller (-c). Compared to the prototypes, armament was beefed up from a pair of 20mm Ho-5 and a pair of 30mm Ho-155-I cannons in the wings to four of the new, more compact Ho-155-II cannons (originally designed for the unsuccessful Ki-102 assault aircraft and optimized for wing installation).

 

All pre-production Ki-104-Is were allocated to an independent IJA Headquarter Flight where they were tested alongside established fighters in the defence of the Tokyo region. Based on this 3rd Independent Flight's unit marking, a completely black tail with the unit's emblem, the Ki-104s were inofficially called Ic '黒の尾'/'Kurono-'o, which literally means "Black Tail".

 

The first operational Ki-104s reached this unit in spring 1945 and saw limited use against the incoming streams of B-29 bombers (2 unconfirmed downings in the Tokyo region). After these initial contacts that left a serious impression the new type received the USAF code name "Cooper", but the hostilities' soon end however stopped any further work and serial production. No Ki-104 survived the war.

The kit and its assembly:

This whif is the result of many ideas and occasions. First of all, I had a leftover six-blade propeller from a Hasegawa J7W Shinden in stock. Then I recently had an eye on kits of late Japanese high altitude fighters with turbosuperchargers, like the Ki-91-II or the Ki-106. These are available from RS Models, but rare and rather costly. And I wondered how a P-47 might look like without its deep belly? All this was finally thrown into a big idea stew, and the Ki-104 is the home-made hardware result!

 

As a side note: the Ki-104 was a real IJA project, AFAIK based/related to the Tachikawa Ki-94-I twin-boom/push-pull high altitude fighter, a re-worked, more conventional design. Information is sparese and it never reached any hardware stage and remained a paper project as the Rikugun Kogiken Ki-104; I just "revived" the number for my whif, but maybe the real Ki-104 could have looked like it... ;-)

 

The kit is a bashing of various parts and pieces:

- Fuselage and wing roots from an Academy P-47-25

- Wings from an Ark Model Supermarine Attacker (ex Novo)

- Tail fin is a modified part of a Matchbox Ju 188 stabilizer

- The stabilizers are outer sections from a Matchbox Douglas F3D Skyknight

- Cowling comes from an ART Model Grumman F8F Bearcat, the engine was scratched

- Propeller from a Hasegawa J7W Shinden

- Main wheels from a Matchbox F6F Hellcat

 

My choice fell onto the Academy Thunderbolt because it has engraved panel lines, offers the bubble canopy as well as good fit and detail. The belly duct had simply been sliced off, and the opening later faired over with styrene sheet and putty.

The Bearcat cowling was chosen because it had very good fitting width in order to match with the P-47 fuselage, and it turned out to be a very good choice - even though I had to add a dorsal connection, a simple styrene wedge, to create a good profile.

Inside, the engine consists of a reversed Hobby Boss F6F engine, with a fan dummy that covers any view on non-existent interior details... A styrene tube was added, into which a metal axis can be inserted. The latter holds the propeller, so that it can spin with little hindrance.

 

The Attacker wings were chosen because of their "modern" laminar profile - the Novo kit is horrible, but acceptable for donations. And the risen panel lines and rivets should later do great work during the weathering process... OOB, the Attacker wings had too little span for the big P-47, so I decided to mount the Thunderbolt's OOB wings and cut them at a suitable point: maybe 0.5", just where the large wheel fairings for the main landing gear ends.

The intersection with the Attacker wings is almost perfect in depth and width, relatively little putty work was necessary. I just had to cut out new landing gear well parts.

 

With the new wing shape, the tail surfaces had to be changed accordingly, with parts from a Matchbox Skyknight and a highly modified piece from a Matchbox Ju 188 stabilizer.

 

The OOB cockpit and landing gear was retained, I just replaced the main wheels with slightly more delicate alternatives from a Matchbox F6F Hellcat.

 

Once the basic bodywork was done I added the exhaust arrangement under the fuselage; the outlets are oil cooler parts from a Fw 190A, the air scoop once belonged to a Martin Marauder and the long ducts are actually HO scale roof rails. The oil cooler under the engine comes from a Hobby Boss La-7.

 

Pretty wild mix, but it works surprisingly well!

  

Painting and markings:

Even though this was supposed to become a late WWII IJA fighter, I did neither want the stereotype NMF look nor the classic green/grey livery or a respective mottled scheme. What I finally settled upon, though, took a long while to manifest, and it looks ...odd.

 

I wanted a camouflage scheme, but none of the more exotic real world options was fine for me; there had been fighters with black upper surfaces, bright blue ones, or blue mottle on top of NMF. But all this did not convince me, and I eventually created an experimental scheme. And the paint was supposed to look heavily worn, as if the paint had been applied directly onto the bare metal, without primer, so that it chips and flakes off easily.

 

The tones were supposed to be suitable for high altitudes, but not the classic IJA colors - nothing even close. eventuelly I came up with an all-around turquoise green (ModelMaster Fulcrum Grey Green) plus a pale grey-green (ModelMaster RAF Dark Slate Grey) as contrast for the upper sides. Sick combination, yes, esp. with the Aluminum shining through, which was applied first as a kind of acrylic primer. The camouflage paint was carefully brushed on top of that, with panel-wise strokes from back to front. Tedious, but effective.

 

The black tail was applied similarly, it is a free interpretation of real IJA markings; for instance, the 244th Sentai arcraft bore all-red tail sections. Black is an uncommon color, but since I wanted to create fictional squadron markings, too, this was a suitable concept. And it looks cool and mysterious...

 

The cockpit interior was painted with Aodake Iro (Modelmaster), the section behind the pilot's seat and where the sliding canopy moves on the outside, were painted with IJA Dark Green - just an odd idea. In front of the cockpit a black anti glare panel was added. The landing gear and the respective wells were painted with Steel Metallizer (just to set them apart from the lighter Aluminum all around). The propeller was painted in reddish brown tones, the spinner in Humbrol 160 and the blades in 173.

 

After this basic painting the kit received a black ink wash, and decals were applied. These were taken from various aftermarket sheets, including generic, white and yellow sheet for the Home Defence markings on wings and fuselage, the white fuselage trim or the yellow ID markings on the wings' leading edges.

 

As next step the complete kit was carefully wet-sanded, primarily from front to back, so that more of the aluminum primer showed through, the decals (esp. the Hinomaru) were worn out and the camouflage paint on top lost some of its hard edges.

The sanding residues had to be cleaned away thoroughly (with a soft toothbrush and lots of water), and then, repairs, e .g. where the bare plastic came through, as well as extra effects with dry-painted, lighter camouflage tones were done. Final cosmetics also include oil and dirt stains with Tamiya"Smoke", also applied by brush.

 

Once everything was dry and clean (despite the kit's look), everything was sealed under a coat of varnish - a 3:1 mix of matt and gloss Revell Acrylics.

 

A complex and lengthy painting process, but I think the effort paid out because the procedure mimicks the structure and look of a worn paint job instead of trying to look like it when you paint a cammo scheme and add metal effects "on top". This works for small chips, but not for the flaked look I had been looking for.

 

The Ki-104 turned out to be a very conclusive kitbashing - I think that the P-47-with-Attacker-wings-and-new-cowling bears more potential, and I might try it again, e. g. for a naval Thunderbolt development?

Some background:

The Gloster Glaive was basically a modernized and re-engined variant of the successful, British-built Gloster Gladiator (or Gloster SS.37), the RAF’s final biplane fighter to enter service. The Gladiator was not only widely used by the RAF at the dawn of WWII and in almost every theatre of operations, but also by many other nations. Operators included Norway, Belgium, Sweden, Greece, Latvia, Lithuania or Nationalist China, and while the RAF already opted for more modern monoplanes, Gloster saw the opportunity to sell an updated Gladiator to countries which were not as progressive.

Originally designated Gladiator Mk. IV, the machine received many aerodynamic refinements and the motor was changed from a draggy radial to a liquid-cooled inline engine. The latter was the new Rolls Royce Peregrine, a development of the Kestrel. It was, in its original form, a 21-litre (1,300 cu in) liquid-cooled V-12 aero engine ), delivering 885-horsepower (660 kW). The engine was housed under a streamlined cowling, driving a three blade metal propeller, and was coupled with a ventral radiator bath, reminiscent of the Hawker Fury biplane’s arrangement.

 

Structural improvements included an all-metal monocoque fuselage and stabilizers, as well as new wings and streamlined struts with reduced bracing. The upper wing was enlarged and of all-metal construction, too, while the lower wings were reduced in span and area, almost resulting in a sesquiplane layout. The total wing area was only marginally reduced, though.

The fixed landing gear was retained, but the main wheels were now covered with spats. The pilot still sat in a fully enclosed cockpit, the armament consisted of four machine guns, similar to the Gladiator. But for the Glaive, all Browning machine guns were synchronized and mounted in the fuselage: one pair was placed on top of the cowling, in front of the cockpit. Another pair, much like the Gladiator’s arrangement was placed in the fuselage flanks, below the exhaust outlets.

 

Compared with the Gladiator, the design changes were so fundamental that Gloster eventually decided to allocate a separate designation – also with a view to the type’s foreign marketing, since a new aircraft appeared more attractive than another mark of a pre-war design. For the type’s virgin flight in late 1938 the name “Glaive” was unveiled to the public, and several smaller European air forces immediately showed interest, including Greece, Croatia, Turkey, Portugal and Egypt.

 

Greece was one of the initial customers, and the first of a total of 24 aircraft for the Hellenic Air Force was delivered in early 1939, with 24 more on order (which were never delivered, though). The initial batch arrived just in time, since tension had been building between Greece and Italy since 7 April 1939, when Italian troops occupied Albania. On 28 October 1940, Italy issued an ultimatum to Greece, which was promptly rejected. A few hours later, Italian troops launched an invasion of Greece, initiating the Greco-Italian War.

 

The Hellenic Gloster Glaives were split among three Mirae Dioxeos (Fighter Squadrons): the 21st at Trikala, 22nd at Thessaloniki and 23rd at Larissa. When Italy attacked in October 1940, the British fighter was, together with the PZL 24, the Greeks' only modern type in adequate numbers. However, by late 1940, the Gloster Glaive was already no longer a front-runner despite a powerful powerplant and satisfactory armament. It had no speed advantage over the Fiat Cr.42 nor could it outfly the nimble Italian biplane, and it was much slower than the Macchi MC.200 and the Fiat G.50 it was pitted against. Its agility was the only real advantage against the Italian fighters, whose reliance on the slow firing Breda-SAFAT 12.7mm machine guns proved detrimental.

 

Anyway, on 5 April 1941, German forces invaded Greece and quickly established air superiority. As the Allied troops retreated, British and Hellenic forces covered them, before flying to Crete during the last week of April. There, the refugee aircraft recorded a few claims over twin-engine aircraft before being evacuated to Egypt during the Battle of Crete.

 

Overall, the Glaives performed gallantly during the early period of the conflict, holding their own against impossible numerical odds and despite the fact that their main target were enemy bombers which forced them to fight at a disadvantage against enemy fighters. Italian claims of easy superiority over the Albanian front were vastly over-rated and their kill claims even exceeded the total number of operational fighters on the Greek side. Total Greek fighter losses in combat came to 24 a/c with the Greek fighter pilots claiming 64 confirmed kills and 24 probables (about two third bombers).

 

By April 1941, however, lack of spares and attrition had forced the Hellenic Air Force to merge the surviving seven Glaives with five leftover PZL.24s into one understrength squadron supported by five Gloster Gladiators Mk I & II and the two surviving MB.151s. These fought hopelessly against the Luftwaffe onslaught, and most aircraft were eventually lost on the ground. None of the Hellenic Gloster Glaives survived the conflict.

The kit and its assembly:

The fictional Gloster Glaive started quite simple with the idea of replacing the Gladiator’s radial with an inline engine. But this soon did not appear enough for an update – the Peregrine hardly delivered much more power than the former Mercury, so I considered some structural updates, too. Most of them comprised the replacement of former fabric-covered structures, and this led conceptually to a kitbash with only some Gladiator fuselage and tail parts left.

 

The basis is (once more) the very nice Matchbox Gloster Gladiator, but it was heavily modified. As an initial step, fuselage, fin and stabilizers (all OOB parts) lost their rib-and-fabric structure, simply sanded away. A minor detail, but it changes the overall look of the aircraft a lot, making it appear much more modern.

The fuselage was left without the OOB radial, and instead a leftover Merlin front end from an Airfix Hurricane (ca. 1cm long, left over from one of my first whif builds ever, a Hurricane with a radial engine!) was added. The lines match pretty well: the side profile looks sleek, if not elegant, but the Gladiator fuselage turned out to be wider than expected. Some major body work/PSR was necessary to integrate the new nose, but the result looks very good.

 

The liquid-cooled engine necessitated a radiator somewhere on the airframe…! Since I wanted the nose to remain slim and streamlined I eventually placed the radiator bath under the fuselage, much like the arrangement of the Hawker Fury biplane. The radiator itself comes from a late Spitfire (FROG kit).

The exhaust was taken from the Hurricane kit, too, and matching slits dug into the putty nose to take them. The three blade propeller is a mash-up, too: the spinner belongs, IIRC, to an early Spitfire (left over from an AZ Models kit) while the blades came from a damaged Matchbox Brewster Buffalo.

 

The Gladiator’s fuselage flank machine guns were kept and their “bullet channels” extrapolated along the new cowling, running under the new exhaust pipes. Another pair of machine guns were placed on top of the engine – for these, openings were carved into the upper hull and small fairings (similar to the Browning guns in the flanks) added. This arrangement appeared plausible to me, since the Gladiator’s oil cooler was not necessary anymore and the new lower wings (see below) were not big enough anymore to take the Gladiator’s underwing guns. Four MGs in the fuselage appears massive – but there were other types with such an arrangement, e.g. the Avia B-534 with four guns in the flanks and an inline engine.

 

The wings are complete replacements: the upper wing comes from a Heller Curtiss SBC4, while the lower wings as well as the spats (on shortened OOB Gladiator struts) come from an ICM Polikarpov I-153. All struts were scratched. Once the lower wings were in place and the relative position of the upper wing clear, the outer struts were carved from 1mm styrene sheet, using the I-153 design as benchmark. These were glued to the lower wing first, and, once totally dry after 24h, the upper wing was simply glued onto the top and the wing position adjusted. This was left to dry another 24h, and as a final step the four struts above the cowling (using the OOB struts, but as single parts and trimmed for proper fit) were placed. This way, a stable connection is guaranteed – and the result is surprisingly sturdy.

 

Rigging was done with heated sprue material – my personal favorite for this delicate task, and executed before painting the kit started so that the glue could cure and bond well.

  

Painting and markings:

The reason why this aircraft ended in Greek service is a color photograph of a crashed Hellenic Bloch M.B. 152 (coded ‘D 177’, to be specific). I guess that the picture was post-colored, though, because the aircraft of French origin sports rather weird colors: the picture shows a two-tone scheme in a deep, rather reddish chestnut brown and a light green that almost looks like teal. Unique, to say the least... Underside colors couldn’t be identified with certainty in the picture, but appeared like a pale but not too light blue grey.

 

Anyway, I assume that these colors are pure fiction and exaggerated Photoshop work, since the few M.B. 152s delivered to Greece carried AFAIK standard French camouflage (in French Khaki, Chestnut Brown and Blue-Grey on the upper surfaces, and a very light blue-grey from below). I’d assume that the contrast between the grey and green tones was not very obvious in the original photograph, so that the artist, not familiar with WWII paint schemes, replaced both colors with the strange teal tone and massively overmodulated the brown.

 

As weird as it looked, I liked this design and used it as an inspirational benchmark for my Hellenic Glaive build. After all, it’s a fictional aircraft… Upper basic colors are Humbrol 31 (RAF Slate Grey) and 160 (German Camouflage Red Brown), while the undersides became French Dark Blue Grey (ModelMaster Authentics 2105). The result looks rather odd…

Representing a combat-worn aircraft, I applied a thorough black ink wash and did heavier panel shading and dry-brushing on the leading edges, along with some visible touches of aluminum.

 

The Hellenic roundels come from a TL Modellbau aftermarket sheet. The tactical code was puzzled together from single letters, and the Greek “D” was created from single decal strips. For better contrast I used white decals – most Hellenic aircraft of the time had black codes, but the contrast is much better, and I found evidence that some machines actually carried white codes. The small fin flash is another free interpretation. Not every Hellenic aircraft carried these markings, and instead of painting the whole rudder in Greek colors I just applied a small fin flash. This was created with white and blue decal strips, closely matching the roundels’ colors.

 

Finally, after some soot stains around the guns and the exhausts, the kit was sealed with matt acrylic varnish.

  

Modified beyond recognition, perhaps…? The fictional Gloster Glaive looks IMHO good and very modern, just like one of those final biplane designs that were about to be outrun by monoplanes at the brink of WWII.

Some background:

The "Entwicklung" tank series (= "development"), more commonly known as the E-Series, was a late-World War II attempt by Germany to produce a standardized series of tank designs. There were to be six standard designs in different weight classes, from which several specialized variants were to be developed. This intended to reverse the trend of extremely complex tank designs that had resulted in poor production rates and mechanical unreliability.

 

The E-series designs were simpler, cheaper to produce and more efficient than their predecessors; however, their design offered only modest improvements in armor and firepower over the designs they were intended to replace, such as the Jagdpanzer 38(t), Panther Ausf.G or Tiger II. However, the resulting high degree of standardization of German armored vehicles would also have made logistics and maintenance easier. Indeed, nearly all of the E-series vehicles — up through and including the E-75 — were intended to use what were essentially the Tiger II's eighty centimeter diameter, steel-rimmed road wheels for their suspension, meant to overlap each other (as on the later production Tiger I-E and Panther designs that also used them), even though in a much simplified fashion.

 

Compared with the earlier designs, the amount of drilling and machining involved in producing the Standardpanzer designs was reduced drastically, which would have made them quicker, easier and cheaper to produce, as would the proposed conical spring system, replacing their predecessors' torsion bar system which required a special steel alloy.

 

Focus of initial chassis and combat vehicle development was the E-50/75 Standardpanzer, designed by Adler, both being mostly identical and only differing in armor thickness, overall weight and running gear design to cope with the different weights.

 

There were also lighter chassis variants, though, including the light E-5 and E-10 for armored, tracked reconnaissance vehicles and the E-25. The E-25 designs, in the 25-50 tonnes weight class, were to be the replacements of all Panzer III and Panzer IV based designs, with Alkett, Argus and Adler, with involvement of Porsche. This family would include medium reconnaissance vehicles, medium Jagdpanzer and heavy Waffenträger, using five Tiger II style road wheels per side, combined with "slack-track" design. Track propulsion was switched to a rear drive sprocket, as a consequence of mating the engine and the gearbox into a tail-mounted, single and very compact power pack that made the voluminous and heavy power train through the hull obsolete. This allowed the gun mount to be directly attached to the hull floor, which lowered the overall silhouette, and the gained space offered more room for the crew’s operations as well as for ammunition storage.

 

The medium tank hunter received high priority and the project was called Jagdpanzer E-25/88 and ran under the inventory ordnance number "SdKfz. 198"; . It was to replace various Panzer IV tank hunters and the light "Hetzer" from 1945 onwards, which all either suffered from insufficient firepower, lack of mobility, or armor. Another tank the E-25/88 would replace was the excellent but complex and expensive Jagdpanther with its 8.8 cm Pak 43/3 or 43/4 L/71 cannon.

 

The Jagdpanzer E-25/88 was to eradicate all problems of the Panzer IV tank hunter family and combine the benefits from all former types, including the powerful 8.8cm PaK, which could take down any Allied tank around late 1944 at considerably distances. Even though the E-25 tank hunter was initially to be outfitted with the proven 7.5 cm/L70 gun from the Jagdpanzer IV and the Panther battle tank, it was surmised that this armament would not be enough for the enemy's next generation tanks.

Beyond its heavy armament, the new tank hunter was to offer good protection through armor and hull shape alike, as well as high mobility, while keeping overall weight at around 30 tons (the Jagdpanzer IV weighed roundabout 25 tons, while the much bigger Jagdpanther weighed 45 tons) and overall size smaller than the Jagdpanther.

Heavier tank hunters than the E-25/88, based of the new E-50 and E-75 chassis were under development in parallel, but they were all to carry heavier guns, including the 12.8 cm PaK and newly developed 10.5 cm and 13 cm cannons. An E-100 SPG on the drawing board (called "Krokodil") was to carry a 15 cm or even a 17.5 cm anti tank gun.

 

In late 1944, with the Allied invasion in the West and rising pressure from the East, anti tank and assault SPGs were direly needed and the rejuvenation of the German tank force was sped up in a hurry. As a consequence the Jagdpanzer E-25/88 was prematurely ushered into production before the medium E-25 chassis development had been fully completed.

As a stopgap solution, initial production tanks were outfitted with a Henschel running gear that dated back to the canceled VK20 and VK30 tank program, and these vehicles were later re-designated SdKfz. 198/1 (while the vehicles with the new/standardized running gear became the SdKfz. 198/2). However, its overlapped and interleaved roadwheel-based suspension system (called “Schachtellaufwerk”) was a considerable improvement against the Panzer IV design, even though it was more complex than the final E-25 system. Around 80 vehicles were produced with the Henschel suspension until production was switched to the simplified Alkett suspension based on the unified wheels of the bigger Einheitspanzer types.

 

The upper hull remained basically the same throughout production, though, and was based on proven principles. To accommodate the heavy-calibre gun, much as on previous unturreted tank destroyers, the glacis plate and sloped hull sides of the Jagdpanzer E-25/88 were extended up into an integral, turretless fixed casemate as part of the main hull itself, providing a relatively roomy interior. The Jagdpanzer E-25/88 had side armour of up to 60 mm, frontal and gun mantlet armour was 80mm. The E-25's engine was a Maybach HL 101 with 550 PS (539 hp, 341 kW), another recognizable improvement in comparison with its frequently underpowered predecessors. Maximum speed was up to 52 km/h (32 mph) on level ground, and the interleafed running gear allowed a smooth ride and high speed even in rough terrain - even though the complex design meant that the wheels could clog up easily with heavy mud or snow.

 

The gun was mounted in a central "Saukopf" mantlet, similar to the Jagdpanzer IV, and had a limited traverse of 11° to each side, with an elevation of −8° to +15°. 50 rounds for the main gun could be stowed. A single 7.92 mm MG-34 machine gun for frontal defence and against soft ground targets was carried in a ball mount on the right side of the front glacis plate, operated by the wireless operator. Another MG-34 was mounted in a remotely controlled turret on top of the hull, operated by the commander who sat under a cupola with seven periscopes for a good field of view. This machine gun was, in later production tanks, to be replaced by a 30mm MK 108 (actually a compact, belt-fed aircraft machine gun), but this was never carried out since MK 103 production was completely allocated to the Luftwaffe. The driver sat on the left. The gunner had a visual rangefinder and a periscope telescopic sight. The periscope - linked to the gun mount - was under an armored housing on the roof.

 

In service the vehicle was, due to its crouched silhouette, unofficially called "Dachs" (Badger), a name that was quickly adopted in official circles, too. The first vehicles reached Western front line units along the Rhine in March 1945. They proved to be very successful and popular with its crews, because the tank was agile, easy to handle and less cramped than most of its predecessors. Total production reached 250 vehicles until the end of hostilities, and many of the E-25/88s design features were later incorporated into the post WWII “Jagdpanzer Kanone” for the German Bundeswehr.

The kit and its assembly:

It does not look spectacular, but this compact tank hunter is a major kitbashing, inspired by - but not necessarily an exact model of - the real but unrealized German E-25 Jagdpanzer project.

 

Things started with a leftover chassis from a Trumpeter "Sturer Emil" SPG with an early interleaf suspension design and a relatively long hull. I wanted to save it and incorporate it into a Heer '46 design, and soon the idea of a Jagdpanzer IV successor was born. Selling it as an E-25 design and incorporating a bigger gun was a logical step.

 

The build was very pragmatic. The lower hull with the wheel attachments was taken OOB, but it was shortened by 5mm. This was achieved by simply taking away a plug behind the last road wheel and in front of the sprocket wheel, which was moved from the front to the rear end.

While this sounds simple, the attachment points’ different diameters and the need for a sturdy construction (due to the kit’s vinyl tracks) posed quite a challenge. In the wake of this modification, the track’s support wheels were deleted, too, for the E-25’s simplified “slack track” layout. The tracks were shortened accordingly, and mounted/fixed with super glue (as one of the final steps after painting).

 

The upper hull comes basically from an Armorfast Jagdpanther, after several trials with a Jagdpanzer IV, a Brummbär and even a potentially scratched casemate. The Jagdpanther hull was reduced in height, though, and also slightly shortened, so that the new tank would be more compact than a Jagdpanther and also differ in the silhouette.

 

In order to change the look even more, the “Saukopf” gun mantlet from a Jagdpanzer IV/70 was implanted (even though with an 8,8cm barrel), as well as the vehicle’s protective shields for the motor deck. Overall hull width was adapted to the Sturer Emil tracks through mudguards.

 

The machine gun turret was scratched, and some other details changed or added, including some periscopes, a Panzer IV commander cupola and some equipment pieces on the mudguards.

  

Painting and markings:

This time, I wanted a disruptive scheme for this tank hunter, and adopted a rather simple livery for the E-25/88: a uniform RAL 6003 Olivgrün for the upper hull (appied with a rattle can, plus a hush with RAL 6011 on the upper surfaces), with a dense, irregular pattern of sand/yellow blotches - lighter than the authentic RAL 7028 Dunkelgelb, though (I have used Humbrol 103, Cream).

Wheels and the lower hull flanks (behind the running gear) were painted in RAL 7028 Dunkelgelb (RAL 8000, which comes pretty close, IMHO).

 

Similar schemes were, for instance, applied to some Ferdinand tank Hunters, operated in Italy and the Eastern Front, but also on Jagdpanthers at the Western front (e. g. in Belgium). The result reminds a bit of a Giraffe, or of the unique British "net" scheme applied to tanks on Malta.

 

On top of the basic paintwork, a dark brown washing was added and the edges further emphasized through dry-brushing with light grey and pale sand tones, plus some acrylic silver.

 

Once the wheels and tracks were fitted into place and the few decals applied, a coat of matt acrylic varnish was added. Finally, dust and dry mud were simulated with mixed pigments, applied with a soft brush onto wet stains of varnish.

  

This E-25 tank hunter model looks pretty conclusive, and at first glance it looks very German, because it incorporates many typical design features. But the more you look the more “unique” it looks, e. g. through the low Schachtellaufwerk, the lowered Jagdpanther upper hull and its combination with the Saukopf gun mantlet from the Jagdpanzer IV. It looks very purposeful, and the paint scheme appears to be very effective, too, blurring the outlines and details well.

Some background:

The North American FJ-4 Fury was a swept-wing carrier-capable fighter-bomber for the United States Navy and Marine Corps. The final development in a lineage that included the Air Force's F-86 Sabre, the FJ-4 shared its general layout and engine with the earlier FJ-3, but, compared to that of the FJ-3, the FJ-4's new wing was much thinner, with a six percent thickness-to-chord ratio, and featured skin panels milled from solid alloy plates. It also had an increased area and tapered more sharply towards the tips. Slight camber behind the leading edge improved low speed characteristics. The main landing gear design had to be considerably modified to fold wheel and strut within the contours of the new wing. The track of the main wheels was increased, and because they were closer to the center of gravity, there was less weight on the nosewheel. Wing folding was limited to the outer wing panels.

 

The FJ-4 was intended as an all-weather interceptor, a role that required considerable range on internal fuel. The FJ-4 had 50% more fuel capacity than the FJ-3 and was lightened by omitting armor and reducing ammunition capacity. The new wing was "wet"; that is, it provided for integral fuel tankage. The fuselage was deepened to add more fuel and had a distinctive "razorback" rear deck. A modified cockpit made the pilot more comfortable during the longer missions. The tail surfaces were also extensively modified, had a thinner profile and featured an extended, taller fin. The overall changes resulted in an aircraft that had little in common with the earlier models, although a family resemblance was still present.

 

The FJ-4 was developed into a family of aircraft. Of the original order for 221 FJ-4 day fighters, the last 71 were modified into the FJ-4B fighter-bomber version. This had a stronger wing with six instead of four underwing stations and stronger landing gear. Additional aerodynamic brakes under the aft fuselage made landing safer by allowing pilots to use higher thrust settings and were also useful for dive attacks. External load was doubled. The most important characteristic of the FJ-4B was, since the Navy was eager to maintain a nuclear role in its rivalry with the Air Force, that it was capable of carrying a nuclear weapon on the inboard port station. For the delivery of nuclear weapons, the FJ-4B was equipped with the Low-Altitude Bombing System (LABS), and with this capability it replaced the carrier-based A-3 Skywarrior bombers, which were not suited well for the new low-level approach tactics.

 

In April 1956, the Navy ordered 151 more FJ-4Bs, 10 US Navy squadrons became equipped with the FJ-4B, and the type was also flown by three Marine squadrons. At the same time, the Navy requested a carrier-borne fighter with all-weather capability, radar-guided missiles and a higher performance. This new type was to replace several 1st generation US Navy jets, including the ponderous and heavy Douglas F3D Skyknight, the lackluster Vought F7U as well as the Grumman F9F-8 Cougar. This requirement led to the Douglas F4D Skyray and North American’s FJ-5, another thorough modification of the Fury’s basic design and its eventual final evolution stage.

 

North American’s FJ-5 was designed with compact dimensions in mind, so that the type could be operated on older Essex Class carriers, which offered rather limited storage and lift space. At the time of the FJ-5’s conception, several of these carriers were still in service – and this argument led to an order for the FJ-5 in addition to the F4D.

 

For the FJ-5, the FJ-4’s aerodynamic surfaces were retained, but the fuselage had to be modified considerably in order to accept an APQ-50A radar with a parabolic 24 inches diameter antenna in the nose. The radome was placed above the air intake, similar to the F-86D, and coupled with an Aero 13F fire-control system, which together provided full all-weather capability and information on automatic firing of rockets.

A deeper rear fuselage became necessary, too, because the FJ-5 was powered by a reheated J65-W-18 engine (a development of the Armstrong Siddeley Sapphire turbojet, optimized for a naval environment), which delivered up to 10,500 lbf (47 kN) at full power instead of the FJ-4’s original 7,700 lbf (34 kN). This upgrade had, limited by the airframe’s aerodynamics, only marginal impact on the aircraft’s top speed, but the extra power almost doubled its initial rate of climb, slightly raised the service ceiling and markedly improved acceleration and carrier operations handling through a better response to throttle input and a higher margin of power reserves.

 

Internal armament still consisted of four 20mm cannon. These had to be placed lower in the nose now, flanking the air intake underneath the radome. The FJ-4B’s six underwing hardpoints were retained and could carry AIM-9 Sidewinders (both the IR-guided AIM-9B as well as the Semi-Active Radar Homing (SARH) AIM-9C) as well as the new radar-guided medium-range AIM-7C Sparrow, even though the latter only on the outer pylons, limiting their number to four. Up to six pods with nineteen unguided 70 mm/2.75” unguided Mk 4/Mk 40 Folding-Fin Aerial Rocket (Mighty Mouse FFARs) were another armament option.

 

Beyond these air-to-air weapons, a wide range of other ordnance could be carried. This included the AGM-12 “Bullpup” guided missile (which necessitated a guidance pod on the right inner wing hardpoint), bombs or napalm tanks of up to 1.000 lb caliber, missile pods, drop tanks and ECM pods. The FJ-4B’s strike capabilities were mostly retained, even though the dedicated fighter lost the ability to carry and deliver nuclear weapons in order to save weight and internal space for the radar equipment.

 

The first FJ-5, a converted early FJ-4, made its maiden flight in April 1958. After a short and successful test phase, the type was quickly put into production and introduced to service with US Navy and US Marine Corps units. The new fighter was quickly nicknamed “Fury Dog” by its crews, a reminiscence of the USAF’s F-86D “Sabre Dog” and its characteristic nose section, even though the FJ-5 was officially still just called “Fury”, like its many quite different predecessors.

 

With the new unified designation system adopted in 1962, the FJ-4 became the F-1E, the FJ-4B the AF-1E and the FJ-5 the F-1F. From the prolific Fury family, only the FJ-5/F-1F became involved in a hot conflict: in late 1966, the USMC deployed F-1Fs to Vietnam, where they primarily flew escort and top cover missions for fighter bombers (esp. A-4 Skyhawks) from Da Nang AB, South Vietnam, plus occasional close air support missions (CAS) on their own. The Marines’ F-1Fs remained in Vietnam until 1970, with a single air-to-air victory (a North-Vietnamese MiG-17 was shot down with a Sidewinder missile), no losses and only one aircraft seriously damaged by anti-aircraft artillery (AAA) fire.

 

After this frontline experience, a radar upgrade with an AN/APQ-124 was briefly considered but never carried out, since the F-1F showed the age of the original Fifties design – the type already lacked overall performance for an all-weather fighter that could effectively engage supersonic bomber targets or low flying attack aircraft. However, the aircraft was still popular because of its ruggedness, good handling characteristics and compact dimensions.

Other upgrades that would improve the F-1F’s strike capability, e. g. additional avionics to deploy the AGM-62 Walleye glide bomb or the new AGM-65 Maverick, esp. the USMC’s laser-guided AGM-65E variant, were also rejected, because more capable types for both interceptor and attack roles, namely the Mach 2 Douglas F-4 Phantom II and the LTV A-7 Corsair II, had been introduced in the meantime.

Another factor that denied any updates were military budget cuts. Furthermore, the contemporary F-8 Crusader offered a better performance and was therefore selected in favor of the F-1F to be updated to the H-L variants. In the wake of this decision, all F-1Fs still in Navy service were, together with the decommission of the last Essex Class carriers, in 1975 handed over to the USMC in order to purge the Navy’s inventory and simplify maintenance and logistics.

 

FJ-4 and FJ-4B Fury fighter bombers served with United States Naval Reserve units until the late 1960s, while the F-1F soldiered on with the USMC until the early Eighties, even though only in reserve units. A considerable number had the heavy radar equipment removed and replaced by ballast in the late Seventies, and they were used as fighter-bombers, for dissimilar air combat training (simulating Soviet fighter types like the MiG-17 and -19), as high-speed target tugs or as in-flight refueling tankers, since the FJ-5 inherited this capability from the FJ-4, with up to two buddy packs under the wings. A few machines survived long enough to receive a new low-visibility livery.

 

However, even in the USMC reserve units, the FJ-5 was soon replaced by A-4 Skyhawks, due to the age of the airframes and further fleet reduction measures. The last F-1F was retired in 1982, ending the long career of North American’s F-86 design in US service.

 

A total of 1,196 Furies of all variants were received by the Navy and Marine Corps over the course of its production life, including 152 FJ-4s, 222 FJ-4Bs and 102 FJ-5s.

The kit and its assembly:

A project I had on the agenda for a long time. But, due to the major surgeries involved, I have been pushing it away – until the “In the navy” group build at whatifmolders.com came along in early 2020. So I collected my courage, dusted off the donor kits that had already been stashed away for years, and eventually started work.

 

The original inspiration was the F-8 Crusader’s career: I really like the look of the late RF-8s, which were kept long enough in service to receive the Eighties’ Low-Viz USN “Compass Ghost” livery. This looks cool, but also a little wrong. And what if the FJ-4B had been kept in service long enough to receive a similar treatment…?

 

In order to justify a career extension, I made up an all-weather development of the FJ-4B with a radar and a more powerful engine, a kind of light alternative to the Vought A-7. A plausible solution was a mix of FJ-4B and F-86D parts – this sounds easy, but both aircraft and their respective model kits actually have only VERY little in common.

 

At its core, the FJ-5 model is a kitbashing of parts from an Emhar FJ-4B (Revell re-boxing) and an Airfix F-86D. The FJ-4B provided the raised cockpit section with the canopy, spine and fin in the form of a complete transplant, which furthermore had to be extended by about 1cm/0.5” because the F-86D is longer than the Fury. The FJ-4B also provided its wings, stabilizers and the landing gear. The Fury’s ventral arrester hook section, a separate part, was also transferred into the F-86D’s lower rear fuselage, under the openings for the air brakes.

For a more lively look, the (thick!) Fury canopy was sawed into two pieces for open display and the flaps were lowered, too.

 

The cockpit was taken from the Airfix kit, since it would fit well into the lower fuselage and it looked much better than their respective counterparts from the relatively basic Emhar kit, which just comes with a narrow board with a strange, bulky seat-thing. As an extra, the cockpit received side consoles, a scratched gunsight and a different ejection seat that raised the pilot’s position into the Fury’s higher canopy.

 

Since the F-1F was supposed to be a fighter, still equipped with the radar set, I retained the OOB pylons from the Fury with its four launch rails. For an aircraft late in the career, I gave it a reduced ordnance, though, just a pair of drop tanks (left over from a Matchbox F3D Skyknight; I wanted something more slender than the stubby OOB drop tanks from the Emhar Fury kit), plus a better Sidewinder training round (hence its blue body) and a single red ACMI data pod on the outer pylons, as an aerial combat training outfit and nice color highlights on the otherwise dull/grey aircraft.

  

Painting and markings:

As mentioned above, the idea for livery was a vintage aircraft in modern, subdued markings. So I adapted the early USN Compass Ghost scheme, and the F-1F received a two-tone livery in FS 36320 and 36375 (Dark and Light Compass Ghost Grey, Humbrol 128 and 127, respectively) with a high, wavy waterline and a light fin. In front of the cockpit, a slightly darker anti-glare panel in Humbrol 145 (FS 35237) was added, inspired by early USN F-14s in Compass Ghost camouflage.

The radome was painted with Humbrol 156, for a slightly darker/different shade of grey than the aircraft’s upper surfaces – I considered a black or a beige (unpainted glass fiber) radome first, but that would have been a very harsh contrast to the rest.

 

The landing gear as well as the air intake duct were painted glossy white (Humbrol 22), the cockpit became medium grey (Humbrol 140, Dark Gull Gray). The inside of the air brakes as well es the edges of the flaps, normally concealed when they are retracted, were painted in bright red (Humbrol 174). The same tone was also used to highlight the edges of the land gear covers.

 

The grey leading edges on the wings the stabilizers were created with decal sheet strips (generic material from TL Modellbau), the gun blast plates were made with silver decal material.

In order to give the model a worn look, I applied a black ink wash, an overall, light treatment with graphite and some post shading. Some extra graphite was applied around the exhaust and the gun nozzles.

 

The markings were taken for an USMC A-4E/F from a Revell kit (which turned out to be a bit bluish). I wanted a consequent dull/toned-down look, typical for early Compass Ghost aircraft. Later, colored highlights, roundels and squadron markings crept back onto the aircraft, but in the early Eighties many USN/USMC machines were consequently finished in a grey-in-grey livery.

 

Finally, the model was sealed with matt acrylic varnish (Italeri) and the ordnance added.

  

Well, the end result looks simple, but creating this kitbashed Fury all-weather fighter was pretty demanding. Even though both the Fury and the F-86D are based on the same aircraft, they are completely different, and the same is also true for the model kits. It took major surgeries and body sculpting to weld the parts together. But I am quite happy with the outcome, the fictional F-1F looks pretty conclusive and natural, also in the (for this aircraft) unusual low-viz livery.

 

The kit and its assembly:

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

 

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

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

 

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

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

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

 

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

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

 

The ordnance came from various sources. The Sidewinders under the wing tips were taken from a Hasegawa USAF weapon set, representing the state-of-the-art of aerial defence. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-4 and -19 missile pods on the stub wings were taken from the OV-10 kit.

Some background:

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

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

 

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

 

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

 

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

 

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

 

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

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

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

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

 

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

 

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

 

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

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

 

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

 

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

 

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

 

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

 

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

 

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

The kit and its assembly:

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

 

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

 

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

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

 

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

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

 

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

 

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

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

  

Painting and markings:

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

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

 

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

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

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

 

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

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

 

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

  

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

Some background:

The Nakajima Ki-104 was a further development of the Ki-87; the latter was a Japanese high-altitude fighter-interceptor of World War II, a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.

 

The Ki-87 was one of several designs of various manufacturers developed in response to American B-29 Superfortress raids on the Home Islands. The Ki-87 followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began.

 

The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the high-performance, tandem-engine Tachikawa Ki-94-I, while the Ki-87 under the lead of Kunihiro Aoki was developed as a fall-back project, using less stringent requirements.

Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945.

 

The Technical Division of Imperial Army Headquarters made itself felt during the development of the Ki-87 prototype when they insisted upon placing the turbo-supercharger in the rear-fuselage, and from the sixth prototype the Nakajima fighter was to have that arrangement. Construction was further delayed due to problems with the electrical undercarriage and the turbo-supercharger itself. As a consequence, the first Ki-87 prototype was not completed until February 1945; it first flew in April, but only five test flights were completed.

 

A further variant, the Ki-87-II, powered by a 3,000 hp Nakajima Ha217 (Ha-46) engine and with the turbo-supercharger in the same position as the P-47 Thunderbolt. Due to the long development period of the Ki-87, several major structural changes were made, too, that eventually changed the aircraft so much that it received a new, separate kitai number and became the Ki-104.

 

Kunihiro Aoki's new design was approved by the Koku Hombu, and an order was placed for one static test airframe, three prototypes, and eighteen pre-production aircraft. Only 2 prototypes were built in the event; the first was equipped with a single 1,895 kW (2,541 hp) Nakajima Ha219 [Ha-44] engine, driving a 4-blade, but the second one received the stronger Nakajima Ha217 (Ha-46) and a 6-blade propeller.

 

The pre-production machines (Ki-104-I or -Tei) were all produced with Ha217 engines, but featured various four-bladed propeller (-a, -b) designs as well as the new 6-blade propeller (-c). Compared to the prototypes, armament was beefed up from a pair of 20mm Ho-5 and a pair of 30mm Ho-155-I cannons in the wings to four of the new, more compact Ho-155-II cannons (originally designed for the unsuccessful Ki-102 assault aircraft and optimized for wing installation).

 

All pre-production Ki-104-Is were allocated to an independent IJA Headquarter Flight where they were tested alongside established fighters in the defence of the Tokyo region. Based on this 3rd Independent Flight's unit marking, a completely black tail with the unit's emblem, the Ki-104s were inofficially called Ic '黒の尾'/'Kurono-'o, which literally means "Black Tail".

 

The first operational Ki-104s reached this unit in spring 1945 and saw limited use against the incoming streams of B-29 bombers (2 unconfirmed downings in the Tokyo region). After these initial contacts that left a serious impression the new type received the USAF code name "Cooper", but the hostilities' soon end however stopped any further work and serial production. No Ki-104 survived the war.

The kit and its assembly:

This whif is the result of many ideas and occasions. First of all, I had a leftover six-blade propeller from a Hasegawa J7W Shinden in stock. Then I recently had an eye on kits of late Japanese high altitude fighters with turbosuperchargers, like the Ki-91-II or the Ki-106. These are available from RS Models, but rare and rather costly. And I wondered how a P-47 might look like without its deep belly? All this was finally thrown into a big idea stew, and the Ki-104 is the home-made hardware result!

 

As a side note: the Ki-104 was a real IJA project, AFAIK based/related to the Tachikawa Ki-94-I twin-boom/push-pull high altitude fighter, a re-worked, more conventional design. Information is sparese and it never reached any hardware stage and remained a paper project as the Rikugun Kogiken Ki-104; I just "revived" the number for my whif, but maybe the real Ki-104 could have looked like it... ;-)

 

The kit is a bashing of various parts and pieces:

- Fuselage and wing roots from an Academy P-47-25

- Wings from an Ark Model Supermarine Attacker (ex Novo)

- Tail fin is a modified part of a Matchbox Ju 188 stabilizer

- The stabilizers are outer sections from a Matchbox Douglas F3D Skyknight

- Cowling comes from an ART Model Grumman F8F Bearcat, the engine was scratched

- Propeller from a Hasegawa J7W Shinden

- Main wheels from a Matchbox F6F Hellcat

 

My choice fell onto the Academy Thunderbolt because it has engraved panel lines, offers the bubble canopy as well as good fit and detail. The belly duct had simply been sliced off, and the opening later faired over with styrene sheet and putty.

The Bearcat cowling was chosen because it had very good fitting width in order to match with the P-47 fuselage, and it turned out to be a very good choice - even though I had to add a dorsal connection, a simple styrene wedge, to create a good profile.

Inside, the engine consists of a reversed Hobby Boss F6F engine, with a fan dummy that covers any view on non-existent interior details... A styrene tube was added, into which a metal axis can be inserted. The latter holds the propeller, so that it can spin with little hindrance.

 

The Attacker wings were chosen because of their "modern" laminar profile - the Novo kit is horrible, but acceptable for donations. And the risen panel lines and rivets should later do great work during the weathering process... OOB, the Attacker wings had too little span for the big P-47, so I decided to mount the Thunderbolt's OOB wings and cut them at a suitable point: maybe 0.5", just where the large wheel fairings for the main landing gear ends.

The intersection with the Attacker wings is almost perfect in depth and width, relatively little putty work was necessary. I just had to cut out new landing gear well parts.

 

With the new wing shape, the tail surfaces had to be changed accordingly, with parts from a Matchbox Skyknight and a highly modified piece from a Matchbox Ju 188 stabilizer.

 

The OOB cockpit and landing gear was retained, I just replaced the main wheels with slightly more delicate alternatives from a Matchbox F6F Hellcat.

 

Once the basic bodywork was done I added the exhaust arrangement under the fuselage; the outlets are oil cooler parts from a Fw 190A, the air scoop once belonged to a Martin Marauder and the long ducts are actually HO scale roof rails. The oil cooler under the engine comes from a Hobby Boss La-7.

 

Pretty wild mix, but it works surprisingly well!

  

Painting and markings:

Even though this was supposed to become a late WWII IJA fighter, I did neither want the stereotype NMF look nor the classic green/grey livery or a respective mottled scheme. What I finally settled upon, though, took a long while to manifest, and it looks ...odd.

 

I wanted a camouflage scheme, but none of the more exotic real world options was fine for me; there had been fighters with black upper surfaces, bright blue ones, or blue mottle on top of NMF. But all this did not convince me, and I eventually created an experimental scheme. And the paint was supposed to look heavily worn, as if the paint had been applied directly onto the bare metal, without primer, so that it chips and flakes off easily.

 

The tones were supposed to be suitable for high altitudes, but not the classic IJA colors - nothing even close. eventuelly I came up with an all-around turquoise green (ModelMaster Fulcrum Grey Green) plus a pale grey-green (ModelMaster RAF Dark Slate Grey) as contrast for the upper sides. Sick combination, yes, esp. with the Aluminum shining through, which was applied first as a kind of acrylic primer. The camouflage paint was carefully brushed on top of that, with panel-wise strokes from back to front. Tedious, but effective.

 

The black tail was applied similarly, it is a free interpretation of real IJA markings; for instance, the 244th Sentai arcraft bore all-red tail sections. Black is an uncommon color, but since I wanted to create fictional squadron markings, too, this was a suitable concept. And it looks cool and mysterious...

 

The cockpit interior was painted with Aodake Iro (Modelmaster), the section behind the pilot's seat and where the sliding canopy moves on the outside, were painted with IJA Dark Green - just an odd idea. In front of the cockpit a black anti glare panel was added. The landing gear and the respective wells were painted with Steel Metallizer (just to set them apart from the lighter Aluminum all around). The propeller was painted in reddish brown tones, the spinner in Humbrol 160 and the blades in 173.

 

After this basic painting the kit received a black ink wash, and decals were applied. These were taken from various aftermarket sheets, including generic, white and yellow sheet for the Home Defence markings on wings and fuselage, the white fuselage trim or the yellow ID markings on the wings' leading edges.

 

As next step the complete kit was carefully wet-sanded, primarily from front to back, so that more of the aluminum primer showed through, the decals (esp. the Hinomaru) were worn out and the camouflage paint on top lost some of its hard edges.

The sanding residues had to be cleaned away thoroughly (with a soft toothbrush and lots of water), and then, repairs, e .g. where the bare plastic came through, as well as extra effects with dry-painted, lighter camouflage tones were done. Final cosmetics also include oil and dirt stains with Tamiya"Smoke", also applied by brush.

 

Once everything was dry and clean (despite the kit's look), everything was sealed under a coat of varnish - a 3:1 mix of matt and gloss Revell Acrylics.

 

A complex and lengthy painting process, but I think the effort paid out because the procedure mimicks the structure and look of a worn paint job instead of trying to look like it when you paint a cammo scheme and add metal effects "on top". This works for small chips, but not for the flaked look I had been looking for.

 

The Ki-104 turned out to be a very conclusive kitbashing - I think that the P-47-with-Attacker-wings-and-new-cowling bears more potential, and I might try it again, e. g. for a naval Thunderbolt development?

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

 

How it came to be:

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

 

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

 

Some historic background on this plane:

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

 

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

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

 

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

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

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

  

The construction:

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

 

What went into this model:

 

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

- Main body,

- Parts of the outer wings

- Cockpit interior

- Canopy

 

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

- Tailbooms

- Horizontal fin

- Cockpit parts

- Landing gear

- Propeller spinners

 

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

- Outer wings

- Wheels

 

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

- Engine cowling (rear central fuselage)

- Propellers

 

Other smaller donations:

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

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

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

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

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

  

Laying the foundations

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

 

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

 

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

  

The body parts get assembled

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

 

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

 

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

 

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

 

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

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

  

Trouble! ...and even more trouble!

As rough work progressed, some fundamental problems became obvious:

 

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

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

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

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

 

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

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

  

The big picture becomes clear(er)

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

 

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

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

 

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

 

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

  

Armament:

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

 

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

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

 

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

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

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

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

  

Livery and markings:

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

 

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

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

 

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

 

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

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

 

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

 

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

 

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

  

Finally...

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

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

 

And, after all, it is a fictional design!

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

  

Laying the foundations

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

 

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

 

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

  

The body parts get assembled

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

 

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

 

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

 

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

 

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

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

  

Trouble! ...and even more trouble!

As rough work progressed, some fundamental problems became obvious:

 

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

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

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

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

 

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

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

  

The big picture becomes clear(er)

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

 

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

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

 

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

 

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

  

Armament:

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

 

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

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

 

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

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

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

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

  

Livery and markings:

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

 

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

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

 

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

 

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

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

 

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

 

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

 

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

  

Finally...

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

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

 

And, after all, it is a fictional design!

+++ DISCLAIMER +++

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

  

Some background:

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

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

 

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

 

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

 

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

 

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

 

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

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

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

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

 

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

 

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

 

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

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

 

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

 

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

 

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

 

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

 

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

 

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

The kit and its assembly:

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

 

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

 

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

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

 

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

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

 

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

 

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

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

  

Painting and markings:

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

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

 

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

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

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

 

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

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

 

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

  

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

Some background:

The North American FJ-4 Fury was a swept-wing carrier-capable fighter-bomber for the United States Navy and Marine Corps. The final development in a lineage that included the Air Force's F-86 Sabre, the FJ-4 shared its general layout and engine with the earlier FJ-3, but, compared to that of the FJ-3, the FJ-4's new wing was much thinner, with a six percent thickness-to-chord ratio, and featured skin panels milled from solid alloy plates. It also had an increased area and tapered more sharply towards the tips. Slight camber behind the leading edge improved low speed characteristics. The main landing gear design had to be considerably modified to fold wheel and strut within the contours of the new wing. The track of the main wheels was increased, and because they were closer to the center of gravity, there was less weight on the nosewheel. Wing folding was limited to the outer wing panels.

 

The FJ-4 was intended as an all-weather interceptor, a role that required considerable range on internal fuel. The FJ-4 had 50% more fuel capacity than the FJ-3 and was lightened by omitting armor and reducing ammunition capacity. The new wing was "wet"; that is, it provided for integral fuel tankage. The fuselage was deepened to add more fuel and had a distinctive "razorback" rear deck. A modified cockpit made the pilot more comfortable during the longer missions. The tail surfaces were also extensively modified, had a thinner profile and featured an extended, taller fin. The overall changes resulted in an aircraft that had little in common with the earlier models, although a family resemblance was still present.

 

The FJ-4 was developed into a family of aircraft. Of the original order for 221 FJ-4 day fighters, the last 71 were modified into the FJ-4B fighter-bomber version. This had a stronger wing with six instead of four underwing stations and stronger landing gear. Additional aerodynamic brakes under the aft fuselage made landing safer by allowing pilots to use higher thrust settings and were also useful for dive attacks. External load was doubled. The most important characteristic of the FJ-4B was, since the Navy was eager to maintain a nuclear role in its rivalry with the Air Force, that it was capable of carrying a nuclear weapon on the inboard port station. For the delivery of nuclear weapons, the FJ-4B was equipped with the Low-Altitude Bombing System (LABS), and with this capability it replaced the carrier-based A-3 Skywarrior bombers, which were not suited well for the new low-level approach tactics.

 

In April 1956, the Navy ordered 151 more FJ-4Bs, 10 US Navy squadrons became equipped with the FJ-4B, and the type was also flown by three Marine squadrons. At the same time, the Navy requested a carrier-borne fighter with all-weather capability, radar-guided missiles and a higher performance. This new type was to replace several 1st generation US Navy jets, including the ponderous and heavy Douglas F3D Skyknight, the lackluster Vought F7U as well as the Grumman F9F-8 Cougar. This requirement led to the Douglas F4D Skyray and North American’s FJ-5, another thorough modification of the Fury’s basic design and its eventual final evolution stage.

 

North American’s FJ-5 was designed with compact dimensions in mind, so that the type could be operated on older Essex Class carriers, which offered rather limited storage and lift space. At the time of the FJ-5’s conception, several of these carriers were still in service – and this argument led to an order for the FJ-5 in addition to the F4D.

 

For the FJ-5, the FJ-4’s aerodynamic surfaces were retained, but the fuselage had to be modified considerably in order to accept an APQ-50A radar with a parabolic 24 inches diameter antenna in the nose. The radome was placed above the air intake, similar to the F-86D, and coupled with an Aero 13F fire-control system, which together provided full all-weather capability and information on automatic firing of rockets.

A deeper rear fuselage became necessary, too, because the FJ-5 was powered by a reheated J65-W-18 engine (a development of the Armstrong Siddeley Sapphire turbojet, optimized for a naval environment), which delivered up to 10,500 lbf (47 kN) at full power instead of the FJ-4’s original 7,700 lbf (34 kN). This upgrade had, limited by the airframe’s aerodynamics, only marginal impact on the aircraft’s top speed, but the extra power almost doubled its initial rate of climb, slightly raised the service ceiling and markedly improved acceleration and carrier operations handling through a better response to throttle input and a higher margin of power reserves.

 

Internal armament still consisted of four 20mm cannon. These had to be placed lower in the nose now, flanking the air intake underneath the radome. The FJ-4B’s six underwing hardpoints were retained and could carry AIM-9 Sidewinders (both the IR-guided AIM-9B as well as the Semi-Active Radar Homing (SARH) AIM-9C) as well as the new radar-guided medium-range AIM-7C Sparrow, even though the latter only on the outer pylons, limiting their number to four. Up to six pods with nineteen unguided 70 mm/2.75” unguided Mk 4/Mk 40 Folding-Fin Aerial Rocket (Mighty Mouse FFARs) were another armament option.

 

Beyond these air-to-air weapons, a wide range of other ordnance could be carried. This included the AGM-12 “Bullpup” guided missile (which necessitated a guidance pod on the right inner wing hardpoint), bombs or napalm tanks of up to 1.000 lb caliber, missile pods, drop tanks and ECM pods. The FJ-4B’s strike capabilities were mostly retained, even though the dedicated fighter lost the ability to carry and deliver nuclear weapons in order to save weight and internal space for the radar equipment.

 

The first FJ-5, a converted early FJ-4, made its maiden flight in April 1958. After a short and successful test phase, the type was quickly put into production and introduced to service with US Navy and US Marine Corps units. The new fighter was quickly nicknamed “Fury Dog” by its crews, a reminiscence of the USAF’s F-86D “Sabre Dog” and its characteristic nose section, even though the FJ-5 was officially still just called “Fury”, like its many quite different predecessors.

 

With the new unified designation system adopted in 1962, the FJ-4 became the F-1E, the FJ-4B the AF-1E and the FJ-5 the F-1F. From the prolific Fury family, only the FJ-5/F-1F became involved in a hot conflict: in late 1966, the USMC deployed F-1Fs to Vietnam, where they primarily flew escort and top cover missions for fighter bombers (esp. A-4 Skyhawks) from Da Nang AB, South Vietnam, plus occasional close air support missions (CAS) on their own. The Marines’ F-1Fs remained in Vietnam until 1970, with a single air-to-air victory (a North-Vietnamese MiG-17 was shot down with a Sidewinder missile), no losses and only one aircraft seriously damaged by anti-aircraft artillery (AAA) fire.

 

After this frontline experience, a radar upgrade with an AN/APQ-124 was briefly considered but never carried out, since the F-1F showed the age of the original Fifties design – the type already lacked overall performance for an all-weather fighter that could effectively engage supersonic bomber targets or low flying attack aircraft. However, the aircraft was still popular because of its ruggedness, good handling characteristics and compact dimensions.

Other upgrades that would improve the F-1F’s strike capability, e. g. additional avionics to deploy the AGM-62 Walleye glide bomb or the new AGM-65 Maverick, esp. the USMC’s laser-guided AGM-65E variant, were also rejected, because more capable types for both interceptor and attack roles, namely the Mach 2 Douglas F-4 Phantom II and the LTV A-7 Corsair II, had been introduced in the meantime.

Another factor that denied any updates were military budget cuts. Furthermore, the contemporary F-8 Crusader offered a better performance and was therefore selected in favor of the F-1F to be updated to the H-L variants. In the wake of this decision, all F-1Fs still in Navy service were, together with the decommission of the last Essex Class carriers, in 1975 handed over to the USMC in order to purge the Navy’s inventory and simplify maintenance and logistics.

 

FJ-4 and FJ-4B Fury fighter bombers served with United States Naval Reserve units until the late 1960s, while the F-1F soldiered on with the USMC until the early Eighties, even though only in reserve units. A considerable number had the heavy radar equipment removed and replaced by ballast in the late Seventies, and they were used as fighter-bombers, for dissimilar air combat training (simulating Soviet fighter types like the MiG-17 and -19), as high-speed target tugs or as in-flight refueling tankers, since the FJ-5 inherited this capability from the FJ-4, with up to two buddy packs under the wings. A few machines survived long enough to receive a new low-visibility livery.

 

However, even in the USMC reserve units, the FJ-5 was soon replaced by A-4 Skyhawks, due to the age of the airframes and further fleet reduction measures. The last F-1F was retired in 1982, ending the long career of North American’s F-86 design in US service.

 

A total of 1,196 Furies of all variants were received by the Navy and Marine Corps over the course of its production life, including 152 FJ-4s, 222 FJ-4Bs and 102 FJ-5s.

The kit and its assembly:

A project I had on the agenda for a long time. But, due to the major surgeries involved, I have been pushing it away – until the “In the navy” group build at whatifmolders.com came along in early 2020. So I collected my courage, dusted off the donor kits that had already been stashed away for years, and eventually started work.

 

The original inspiration was the F-8 Crusader’s career: I really like the look of the late RF-8s, which were kept long enough in service to receive the Eighties’ Low-Viz USN “Compass Ghost” livery. This looks cool, but also a little wrong. And what if the FJ-4B had been kept in service long enough to receive a similar treatment…?

 

In order to justify a career extension, I made up an all-weather development of the FJ-4B with a radar and a more powerful engine, a kind of light alternative to the Vought A-7. A plausible solution was a mix of FJ-4B and F-86D parts – this sounds easy, but both aircraft and their respective model kits actually have only VERY little in common.

 

At its core, the FJ-5 model is a kitbashing of parts from an Emhar FJ-4B (Revell re-boxing) and an Airfix F-86D. The FJ-4B provided the raised cockpit section with the canopy, spine and fin in the form of a complete transplant, which furthermore had to be extended by about 1cm/0.5” because the F-86D is longer than the Fury. The FJ-4B also provided its wings, stabilizers and the landing gear. The Fury’s ventral arrester hook section, a separate part, was also transferred into the F-86D’s lower rear fuselage, under the openings for the air brakes.

For a more lively look, the (thick!) Fury canopy was sawed into two pieces for open display and the flaps were lowered, too.

 

The cockpit was taken from the Airfix kit, since it would fit well into the lower fuselage and it looked much better than their respective counterparts from the relatively basic Emhar kit, which just comes with a narrow board with a strange, bulky seat-thing. As an extra, the cockpit received side consoles, a scratched gunsight and a different ejection seat that raised the pilot’s position into the Fury’s higher canopy.

 

Since the F-1F was supposed to be a fighter, still equipped with the radar set, I retained the OOB pylons from the Fury with its four launch rails. For an aircraft late in the career, I gave it a reduced ordnance, though, just a pair of drop tanks (left over from a Matchbox F3D Skyknight; I wanted something more slender than the stubby OOB drop tanks from the Emhar Fury kit), plus a better Sidewinder training round (hence its blue body) and a single red ACMI data pod on the outer pylons, as an aerial combat training outfit and nice color highlights on the otherwise dull/grey aircraft.

  

Painting and markings:

As mentioned above, the idea for livery was a vintage aircraft in modern, subdued markings. So I adapted the early USN Compass Ghost scheme, and the F-1F received a two-tone livery in FS 36320 and 36375 (Dark and Light Compass Ghost Grey, Humbrol 128 and 127, respectively) with a high, wavy waterline and a light fin. In front of the cockpit, a slightly darker anti-glare panel in Humbrol 145 (FS 35237) was added, inspired by early USN F-14s in Compass Ghost camouflage.

The radome was painted with Humbrol 156, for a slightly darker/different shade of grey than the aircraft’s upper surfaces – I considered a black or a beige (unpainted glass fiber) radome first, but that would have been a very harsh contrast to the rest.

 

The landing gear as well as the air intake duct were painted glossy white (Humbrol 22), the cockpit became medium grey (Humbrol 140, Dark Gull Gray). The inside of the air brakes as well es the edges of the flaps, normally concealed when they are retracted, were painted in bright red (Humbrol 174). The same tone was also used to highlight the edges of the land gear covers.

 

The grey leading edges on the wings the stabilizers were created with decal sheet strips (generic material from TL Modellbau), the gun blast plates were made with silver decal material.

In order to give the model a worn look, I applied a black ink wash, an overall, light treatment with graphite and some post shading. Some extra graphite was applied around the exhaust and the gun nozzles.

 

The markings were taken for an USMC A-4E/F from a Revell kit (which turned out to be a bit bluish). I wanted a consequent dull/toned-down look, typical for early Compass Ghost aircraft. Later, colored highlights, roundels and squadron markings crept back onto the aircraft, but in the early Eighties many USN/USMC machines were consequently finished in a grey-in-grey livery.

 

Finally, the model was sealed with matt acrylic varnish (Italeri) and the ordnance added.

  

Well, the end result looks simple, but creating this kitbashed Fury all-weather fighter was pretty demanding. Even though both the Fury and the F-86D are based on the same aircraft, they are completely different, and the same is also true for the model kits. It took major surgeries and body sculpting to weld the parts together. But I am quite happy with the outcome, the fictional F-1F looks pretty conclusive and natural, also in the (for this aircraft) unusual low-viz livery.

The kit and its assembly:

A project I had on the agenda for a long time. But, due to the major surgeries involved, I have been pushing it away – until the “In the navy” group build at whatifmolders.com came along in early 2020. So I collected my courage, dusted off the donor kits that had already been stashed away for years, and eventually started work.

 

The original inspiration was the F-8 Crusader’s career: I really like the look of the late RF-8s, which were kept long enough in service to receive the Eighties’ Low-Viz USN “Compass Ghost” livery. This looks cool, but also a little wrong. And what if the FJ-4B had been kept in service long enough to receive a similar treatment…?

 

In order to justify a career extension, I made up an all-weather development of the FJ-4B with a radar and a more powerful engine, a kind of light alternative to the Vought A-7. A plausible solution was a mix of FJ-4B and F-86D parts – this sounds easy, but both aircraft and their respective model kits actually have only VERY little in common.

 

At its core, the FJ-5 model is a kitbashing of parts from an Emhar FJ-4B (Revell re-boxing) and an Airfix F-86D. The FJ-4B provided the raised cockpit section with the canopy, spine and fin in the form of a complete transplant, which furthermore had to be extended by about 1cm/0.5” because the F-86D is longer than the Fury. The FJ-4B also provided its wings, stabilizers and the landing gear. The Fury’s ventral arrester hook section, a separate part, was also transferred into the F-86D’s lower rear fuselage, under the openings for the air brakes.

For a more lively look, the (thick!) Fury canopy was sawed into two pieces for open display and the flaps were lowered, too.

 

The cockpit was taken from the Airfix kit, since it would fit well into the lower fuselage and it looked much better than their respective counterparts from the relatively basic Emhar kit, which just comes with a narrow board with a strange, bulky seat-thing. As an extra, the cockpit received side consoles, a scratched gunsight and a different ejection seat that raised the pilot’s position into the Fury’s higher canopy.

 

Since the F-1F was supposed to be a fighter, still equipped with the radar set, I retained the OOB pylons from the Fury with its four launch rails. For an aircraft late in the career, I gave it a reduced ordnance, though, just a pair of drop tanks (left over from a Matchbox F3D Skyknight; I wanted something more slender than the stubby OOB drop tanks from the Emhar Fury kit), plus a better Sidewinder training round (hence its blue body) and a single red ACMI data pod on the outer pylons, as an aerial combat training outfit and nice color highlights on the otherwise dull/grey aircraft.

  

Painting and markings:

As mentioned above, the idea for livery was a vintage aircraft in modern, subdued markings. So I adapted the early USN Compass Ghost scheme, and the F-1F received a two-tone livery in FS 36320 and 36375 (Dark and Light Compass Ghost Grey, Humbrol 128 and 127, respectively) with a high, wavy waterline and a light fin. In front of the cockpit, a slightly darker anti-glare panel in Humbrol 145 (FS 35237) was added, inspired by early USN F-14s in Compass Ghost camouflage.

The radome was painted with Humbrol 156, for a slightly darker/different shade of grey than the aircraft’s upper surfaces – I considered a black or a beige (unpainted glass fiber) radome first, but that would have been a very harsh contrast to the rest.

 

The landing gear as well as the air intake duct were painted glossy white (Humbrol 22), the cockpit became medium grey (Humbrol 140, Dark Gull Gray). The inside of the air brakes as well es the edges of the flaps, normally concealed when they are retracted, were painted in bright red (Humbrol 174). The same tone was also used to highlight the edges of the land gear covers.

 

The grey leading edges on the wings the stabilizers were created with decal sheet strips (generic material from TL Modellbau), the gun blast plates were made with silver decal material.

In order to give the model a worn look, I applied a black ink wash, an overall, light treatment with graphite and some post shading. Some extra graphite was applied around the exhaust and the gun nozzles.

 

The markings were taken for an USMC A-4E/F from a Revell kit (which turned out to be a bit bluish). I wanted a consequent dull/toned-down look, typical for early Compass Ghost aircraft. Later, colored highlights, roundels and squadron markings crept back onto the aircraft, but in the early Eighties many USN/USMC machines were consequently finished in a grey-in-grey livery.

 

Finally, the model was sealed with matt acrylic varnish (Italeri) and the ordnance added.

  

Well, the end result looks simple, but creating this kitbashed Fury all-weather fighter was pretty demanding. Even though both the Fury and the F-86D are based on the same aircraft, they are completely different, and the same is also true for the model kits. It took major surgeries and body sculpting to weld the parts together. But I am quite happy with the outcome, the fictional F-1F looks pretty conclusive and natural, also in the (for this aircraft) unusual low-viz livery.

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:

In the aftermath of the Second World War, Britain identified a threat posed by the jet-powered strategic bomber and atomic weaponry and thus placed a great emphasis on developing aerial supremacy through continuing to advance its fighter technology, even following the end of conflict. Blackburn Aircraft responded to a 1947 Air Ministry requirement for a high-performance night fighter under Air Ministry specification F.44/46. The specification called for a two-seat night fighter that would intercept enemy aircraft at heights of up to at least 40,000 feet. It would also have to reach a maximum speed of no less than 525 kn at this height, be able to perform rapid ascents and attain an altitude of 45,000 feet within ten minutes of engine ignition.

 

Additional criteria given in the requirement included a minimum flight endurance of two hours, a takeoff distance of 1,500 yards, structural strength to support up to 4g manoeuvers at high speed and for the aircraft to incorporate airborne interception radar, multi-channel VHF radio and various navigational aids. The aircraft would also be required to be economical to produce, at a rate of ten per month for an estimated total of 150 aircraft.

 

Blackburn produced several design proposals in the hope of satisfying the requirement. B.47, drawn up in 1946, was essentially a two-seat Meteor with slightly swept wings. A similar design was also offered to the Royal Navy as the B.49. The later-issued B.76 and B.77 of early 1947 had adopted many of the features that would be distinctive of the later Barghest, including the large, swept wings and the engine nacelles moved to the wing roots, integrated into the fuselage. The two projects differed primarily in role: P.76 was a single-seat day fighter with a V-tail, while P.77 was a two-seat night fighter with a radar and a mid-mounted tail plane.

 

The RAF requirements were subject to some changes, mainly in regards to radar equipment and armaments. Blackburn also initiated some changes, as further research was conducted into the aerodynamic properties of the new swept wings and tail surfaces. For propulsion, the new Armstrong Siddeley Sapphire turbojet engine was chosen and the airframe adapted accordingly.

 

On 13 April 1949 the Ministry of Supply issued instructions to three aircraft manufacturers, Blackburn, Gloster and de Havilland, to each construct four airworthy prototypes of their competing designs to meet the requirement, as well as one airframe each for structural testing. These prototype aircraft were the Gloster GA.5, designed by Richard Walker, the de Havilland DH.110, which held the advantage of also being under consideration for the Royal Navy (and became the Sea Vixen), and the Blackburn B.87, which was a refined B.77 with a slimmed-down fuselage and a swept T-tail.

 

The development of all of these designs was considerably delayed through political cost-cutting measures, the number of prototypes being trimmed down to an unworkable level of two each before the decision was entirely reversed! The B.87 was soon christened Barghest and first prototype was structurally completed in 1951. Following a month of ground testing the first prototype conducted its first flight on 26 November 1951 and the second prototype followed in February 1952 (and was in 1953 used for aerodynamic tests that led to the improved Mk. 3, see below). The third prototype, and the first to be fitted with operational equipment including radar and weapons, first flew on 7 March 1953. The fourth airframe was passed to the Aeroplane and Armament Experimental Establishment (A&AEE) in August 1953 for trials.

 

The original Barghest all-weather fighter was equipped with a British AI.17 radar and powered by two Sapphire Sa.5 engines without afterburner, delivering 6,500 lbf (28.91 kN) thrust each. The aircraft did not have built-in weapons, but could carry various weapon packages in a spacious, ventral weapon bay. Options included a tray with four 30 mm ADEN cannon, three retractable pods with a total of 70 unguided Microcell 2 in (51mm) missiles, or a recoilless 4.5 in gun with 7 rounds in a drum magazine, even though this huge weapon, intended against incoming bomber formations at high altitude, never made it beyond the prototype stage and ground tests. Furthermore, four underwing hardpoints could carry drop tanks (on the inner pair of pylons only), bombs or unguided SNEB rocket pods for a total load of 4.000 lb (1.814 kg).

 

The official production order for the Barghest was issued in mid-1953, together with the Gloster GA.5, which became the Javelin – an unusual decision, but the need for an operational all-weather fighter was so dire that two types were procured at the same time in order to fill the defense gaps as quickly as possible and to have a fall back option at hand immediately. While some delays were incurred, the Barghest's status as a "super priority" for production helped to minimize the time involved in producing each aircraft. Production was assisted by a large order placed by the United States Air Force, purchasing aircraft for the RAF as part of the Mutual Defense Aid Program.

 

On 22 July 1954 the first production aircraft took flight at Leeds, and the Barghest F(AW).1 entered service with the RAF in 1956 with 46 Squadron based at RAF Odiham, England. The Barghests were immediately put to use in an intensive flying program, to rapidly familiarize crews with the type. In order to assist conversion training, twelve machines from the initial production batch were converted into dual control trainers. They lacked the radar equipment and were designated T.2.

 

The introduction of the Barghest allowed the RAF to expand its night-fighter activity considerably. During RAF trials, the type proved readily capable of intercepting jet bombers such as the English Electric Canberra and modern jet fighters, over a hundred miles out to sea, and the Barghest turned out to be quite an agile aircraft with good flying characteristics, despite its size. By the end of July 1959, all remaining Meteor squadrons had been converted to the Barghest and the Javelin.

 

After an initial production batch of 48 F(AW).1 fighters and a dozen T.2 trainers, the upgraded F(AW).3 was introduced in October 1956, which featured several changes and improvements. The biggest external change was the introduction of a modified wing with a dog tooth (tested on the 2nd prototype from 1953 onwards), which enhanced airflow and handling at high speed. Furthermore, the tailplane was modified so that either the rudders could be operated at slow speed or, alternatively, the whole stabilizer at high speed. A bulbous aerodynamic fairing on the fin’s top held the more complicated mechanism.

The Barghest F(AW).3 was furthermore equipped with a more capable AI.22 radar (actually a U.S.-made Westinghouse AN/APQ-43 radar) and it was able to carry up to four IR-guided Firestreak AAMs on pylons under the wings, what significantly improved the aircraft's interceptor capabilities. The aircraft now featured a total of six hardpoints, even though the new, outermost pylons could only carry a single Firestreak missile each. The ventral weapon bay was retained, but, typically, only the pack of four Aden cannon was carried.

 

In order to cope with a higher all-up weight and improve overall performance, the F(AW).3 was powered by Sapphire Sa.6 engines, which delivered 23% more thrust and were recognizable by enlarged air intakes of oval shape instead of the original, circular orifices. Stronger engines with afterburners could not be mounted, though – their addition would have required a severe structural change to the aircraft’s rear fuselage, and this lack of development potential eventually favored the Barghest’s rival, the Gloster Javelin.

 

Beyond newly produced F(AW).3 airframes, most F(AW).1s were eventually upgraded to this standard, and a further twelve F(AW).1s were modified into trainers. All T.2 aircraft received the wing and tail upgrade, but retained the weaker Sapphire Sa.5s, and their designation was eventually changed into T.4.

 

Due to its higher development potential, the Gloster Javelin overshadowed the Barghest during its relatively short career. The last Barghest fighter was already withdrawn from service in 1966, with a total of 125 airframes having been produced, while the Javelin, produced in more than 420 units, kept on serving until 1968. Both types were replaced by the Mach 2-capable BAC Lightning interceptor.

However, the experience gathered from the Barghest's early development was successfully used by Blackburn during the Buccaneer development process for the Royal Navy in the mid-Fifties.

The kit and its assembly:

This kitbash model originally started as an early Fifties all-weather fighter for the Royal Navy, and the idea was a Gloster Meteor night fighter fuselage mated with the engines and swept wings from a Blackburn Buccaneer. However, things change and evolve as ideas turn into hardware (for another submission to the 2018 “RAF Centenary” Group Build at whatifmodelers.com), and so this project gradually transformed into an all-weather fighter for the Royal Air Force, as a rival to the Gloster Javelin, and some other fundamental changes to the original plan as things evolved on the work bench.

 

Work started with a Matchbox Gloster Meteor, from which the fuselage (incl. the NF.14 cockpit with its bubble canopy) and tail cone (w/o fin, though) were taken OOB. Then a Matchbox Buccaneer donated its nose cone and the engine pods, together with the inner wing sections. An initial attempt to use the Buccaneer’s fin and stabilizer was made, but it did not work at all (looked horrible and totally unbalanced!). Instead, I used a leftover fin from a Revell 1:200 Concorde because of its retro shape and depth, and waited for the stabilizers until the wings were mounted, so that size, position and proportions would become clearer.

The nose cone had to be squashed, because its OOB oval diameter would not go onto the circular Meteor front end without problems and major PSR. With some force from a vice and internal stabilization through 2C putty the shape could be successfully modified, though, and blended into the fuselage contours. Looks pretty good and fast!

 

Once the engine nacelles were in place, I initially tried the Buccaneer’s OOB outer wings, but I was not really happy with the look. Their shape did not look “right”, they were a bit too large and just very Buccaneer-esque. After a donor bank safari I found a leftover sprue with wings and stabilizers from a Matchbox Hawker Hunter, and after some measurements and trials I found that they could be quite easily adapted to the Buccaneer’s inner wing stubs, even though this called for more serious surgery and PSR work. The latter was also necessary in order to blend the engine nacelles into the slender Meteor fuselage – messy, but feasible.

 

Alas, one challenge leads to the next one: Once in place, the massive engines created a ventral gap, due to the Meteor’s slender tail section. This was eventually filled with the Matchbox Buccaneer’s extra fuel bomb bay door, simply cut away from the kit, trimmed down and transplanted between the engine nacelles. As a side benefit, its bulged shape would now simulate a fairing for a ventral gun pack, somewhat similar to the CF-100’s arrangement. More PSR ensued, though, and between and around the jet exhausts the fuselage had to be fully re-sculpted.

 

The stabilizers also caused some headaches. With the new Hunter swept wings tips, I also needed new, matching stabilizers. I eventually used the Hunter stabilizers from the surplus Matchbox kit sprue. At first I tried to mate them with a shortened central fairing from the Buccaneer, but this did work even less than the whole Bucc tail, and so I scratched a more slender central fairing for the T-tail on top of the Concorde fin from a piece of sprue. Even though the Hunter stabilizers turned out to look a bit diminutive, I stuck with them since they complement the wing shape so well.

 

The benefit of the Buccaneer engine nacelles is that they come with proper landing gear wells, so that only the landing gear had to be improvises and adapted to the new aircraft and its proportions. I wanted to use the Meteor landing gear, but this turned out to be much too short! So I replaced the front wheel with a respective part from a Matchbox Buccaneer. The main wheels from the Meteor kit were retained, but they had to be extended - with a 5mm styrene tube “plug”, which is, thankfully, well hidden behind the covers.

 

Others small changes/additions are ejection seats in the cockpit instead of the Meteor bucket seats, the jet exhausts were drilled open and an interior was added, and some antennae were placed on the aircraft’s hull.

 

The ordnance was to reflect a typical late Fifties RAF fighter, and so the Barghest received a pair of drop tanks (from a Heller SEPECAT Jaguar, with simplified fins) and a pair of Firestreak AAMs (from a Matchbox BAC Lightning) on a pair of launch rails from an Academy MiG-23.

  

Colors and markings:

As per usual, I rather keep complicated whiffs visually simple, so I used the standard RAF scheme of Dark Green/Dark Sea Grey/Light Aircraft Grey on the Barghest, with the Buccaneer’s typical pattern as benchmark. Humbrol enamels (163, 164 and 166) were used for basic painting.

The cockpit interior became Tar Black (Revell 06), while the landing gear and its respective wells were painted in Aluminum (Humbrol 56). The kit received a light black ink washing and mild post-shading – more for a dramatic than a weathering effect, since RAF machines in the Fifties looked very tidy and clean.

The drop tanks received camouflage and the Firestreaks became white, while their clear seeker cones were painted with a mix of silver and translucent blue. The IR sensors were created with thin decal stripes.

 

The decals come primarily from an Xtradecal BAC Lightning sheet (roundels and 19 Sq. markings – the squadron badges are unfortunately quite large, since they belong to a NMF aircraft), most stencils and the tactical code come from an Airfix Venom trainer and an Italeri Tornado.

 

Finally, the kit was sealed with a matt acrylic varnish, a mix of matt and little semi-gloss Italeri varnish, for a sheen finish.

  

A true kitbashing, made from many well-known RAF ingredients and a disturbing look between odd and familiar! A Buccaneer? No, it’s too scrawny. A Javelin? No, it does not have delta wings, and it’s got a tail sting. A de-navalized Sea Vixen? Well, no twin tail, and anything else does not match either... Despite the puzzling details (or because of them?), the Barghest looks disturbingly British and Fifties, as if it had been created from a profound RAF DNA pool – and it actually is! And with lots of putty. ;-)

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.

Some Background:

Antanas Gustaitis (March 26, 1898 – October 16, 1941) was an officer in the Lithuanian Armed Forces who modernized the Lithuanian Air Force, which at that time was part of the Lithuanian Army. He was the architect or aeronautical engineer who undertook the task to design and construct several military aircraft before WWII broke out.

 

Gustaitis was born in the village of Obelinė, in Javaravas county, in the Marijampolė district. He attended high school in Yaroslavl, and from there studied at the Institute of Engineering and School of Artillery in Petrograd. After joining the Lithuanian Army in 1919, he graduated from the School of Military Aviation as a Junior Lieutenant in 1920. Later that year, he saw action in the Polish-Lithuanian War. By 1922 he began to train pilots, and later became the head of the training squadron. He also oversaw the construction of aircraft for Lithuania in Italy and Czechoslovakia. Gustaitis was one of the founding members of the Aero Club of Lithuania, and later its Vice-President. He did much to promote aviation among the young people in Lithuania, especially concerning the sport of gliding. He also won the Lithuanian Chess Championship in 1922.

 

Between 1925 and 1928, Gustaitis studied aeronautical engineering in Paris. After his graduation he returned to Lithuania and was promoted to deputy Commander-in-Chief of Military Aviation and made chief of the Aviation Workshop (Karo Aviacijos Tiekimo Skyrius) in Kaunas. During this time, he reorganized the workshop and expanded its capability to repair aircraft as well. The aircraft he designed were named ANBO, an acronym for "Antanas Nori Būti Ore", which literally means “Antanas wants to be in the air” in Lithuanian.

 

Between 1925 and 1939, the ANBO design bureau developed, built and flew several trainers, reconnaissance and even fighter aircraft for the Lithuanian air force. The last projects, the ANBO VIII, a light single-engine reconnaissance bomber, and the ANBO IX, a single-seat fighter, were the most ambitious.

The ANBO IX started in 1935 as a light low-wing design with spatted, fixed landing gear and an open cockpit, powered by a British Bristol Mercury 830 hp (619 kW) 9-cylinder radial engine – a very clean all-metal design, outwardly not unlike the contemporary Japanese Nakajima Ki-27 or the Dutch Fokker D.XXI, but a much more modern construction.

A first prototype had been completed in summer 1936 and it flew for the first time on 1st of August, with good flight characteristics, but Gustaitis was not satisfied with the aircraft anymore. More powerful and aerodynamically more efficient engines had become available, and a retractable landing gear would improve the performance of the ANBO IX even more, so that the aircraft was heavily modified during the rest of the year.

 

The large Mercury was replaced with a Pratt & Whitney R-1535 Twin Wasp Junior, a two-row 14-cylinder radial engine with 825 hp and a much smaller frontal area that allowed the ANBO IX’s cowling to be wrapped much tighter around the engine than the Mercury’s former Townend ring, leading to a very aerodynamic overall shape. The oil cooler, formerly mounted starboard flank in front of the cockpit, was moved into a mutual fairing with the carburetor intake under the fuselage behind the engine.

The wings had to be modified to accommodate a retractable main landing gear: to make space for suitable wells, the inner wing section in front of the main spar was deepened, resulting in a kinked leading edge of the wing. The landing gear retracted inwards and was initially completely covered. The tail remained fixed, though, even though the former simple tailskid was replaced with a pressurized rubber wheel for better handling on paved runways.

 

These measures alone improved the ANBO IX’s top speed by 25 mph (40 km/h), and to improve the pilot’s working conditions the originally open cockpit with just a windscreen and a small headrest fairing was covered with a fully closed clear canopy and an enlarged aerodynamic spinal fairing that ended at the fin’s base. This additional space was used to introduce another contemporary novel feature on board: a radio set.

Together with some other refinements on a second prototype (e. g. a smaller diameter of the front fuselage section, an even more streamlined cowling that now also covered two synchronized machine guns above the engine and a recontoured wing/fuselage intersection), which flew in September 1937, top speed rose by another 6 mph (10 km/h) from 460 km/h (285 mph) of the original aircraft to a competitive 510 km/h (317 mph) that put the ANBO IX on a par with many other contemporary European fighter aircraft.

 

In this form the ANBO IX was cleared for production in early 1938, even though the desired R-1535 Twin Wasp Junior was not cleared for export or license production. With the Manfréd Weiss WM K.14 engine from Hungary, a derivative of the French Gnôme-Rhône 14 K with 900 hp, a similar, even slightly more powerful replacement could be quickly found, even though the adaptation of the airframe to the different powerplant delayed production by four months. Beyond a new engine mount, the machine guns in the fuselage and its synchronization gearbox had to be deleted, but the weapons could be moved into the outer wings, so that a total of four machine guns as main armament was retained. Additionally, a single ventral hardpoint was added that could either carry a single bomb with its respective shackles or – more frequently – a drop tank that extended the fighter’s rather limited range.

 

The Lithuanian air force ordered fifty of these machines, primarily to replace its Fiat CR.20 biplane fighters, and several regional export customers like Finland, Estonia and Bulgaria showed interest in the modern ANBO IX, too. Due to the complex all-metal airframe and limited workshop capacities, however, production started only slowly.

The first batch of six ANBO IXs arrived at Lithuanian frontline units in November 1939, more were in the ANBO workshops in Kaunas at that time in various stages of assembly. In 1940, the Lithuanian Air Force consisted of eight Air Squadrons, including reconnaissance, fighter, bomber and training units. However, only the 5th fighter squadron had by the time enough ANBO IXs and trained pilots to be fully operational with the new type. Air Force bases had been established in the cities and towns of Kaunas/Žagariškės, Šiauliai /Zokniai (Zokniai airfield), Panevėžys /Pajuostis. In the summertime, airports in the cities of Palanga and Rukla were also used. A total of 117 aircraft and 230 pilots and observers were listed in the books at that time, but less than ten of them were modern ANBO IX fighters, and probably only half of them were actually operational.

 

Following the Soviet occupation of Lithuania, however, the Lithuanian Air Force was formally disbanded on October 23, 1940. Part of Lithuanian Air Force (77 senior officers, 72 junior officers, 59 privates, 20 aircraft) was reorganized into Red Army's 29th Territorial Rifle Corps Aviation, also referred to as National Squadron (Tautinė eskadrilė). Other planes and equipment were taken over by Red Army's Air Force Bases No. 13 and 213. About third of Tautinė eskadrilė's personnel latter suffered repressions by Soviet authorities, significant share joined June uprising, after the start of German invasion into Soviet Union several pilots of Tautinė eskadrilė and fewer than six planes withdrew with the Soviet army.

The kit and its assembly:

This small aircraft model is the result of a spontaneous kitbashing flash, when I dug through the sprue piles and the spares box. It started with a leftover fuselage from a Mistercraft PZL P-7 fighter, and further searches revealed the wings from a PM Model Fokker D.XXI and the sawn-off wings from a Hobby Boss MS.406. The sprue stash came up with other useful parts like small stabilizers and a landing gear – and it turned out to be the rest of the MS.406, which had originally been butchered to be mated with the P-7 wings to become my fictional Polish RWD-24 fighter prototype. So, as a serious recycling project, I decided to accept the challenge and use the remains of the P-7 and the MS.406 to create a “counterpart” to the RWD-24, and it became the fictional ANBO IX.

 

While the ingredients for a basic airframe were now available, some parts were still missing. Most important: an engine. One option was an early Merlin, left over from a Spitfire, but due to the circular P-7 fuselage I preferred a radial engine. With the cowling from a Japanese Mitsubishi Ha-102 two-row radial (from an Airfix Ki-46 “Dinah”) I found a suitable and very streamlined donor, which received a small three-blade propeller with a scratched spinner on a metal axis inside.

 

The cockpit and the canopy caused more headaches, because the P-7 has an open cockpit with a rather wide opening. For a fighter with a retractable landing gear this would hardly work anymore and finding a solution as well as a suitable donor piece took a while. I initially wanted to use a kind of bubble canopy (with struts, so that it would not look too modern), but eventually rejected this because the proportions would have looked odd – and the overall style would have been too modern.

So I switched to an early Spitfire canopy, which had a good size for the small aircraft, even though it called for a spinal fairing – the latter became the half from a drop tank (IIRC from an Airfix P-61?).

 

Lots of PSR was necessary everywhere to blend the disparate parts together. The cockpit opening had to be partly filled and reshaped, blending both canopy and spine into the hull took several layers.

The area in front of the cockpit (originally holding the P-7’s shoulder-mounted wings) had to be re-sculpted and blended into the Ki-46 cowling.

The ventral area between the wings had also to be fully sculpted with putty, and huge gaps along the wing roots on the wings’ upper surfaces had to be filled and formed, too. No wonder that many surface details disappeared along the way… Nevertheless, the effort was worthwhile, because the resulting airframe, esp. the sleek fuselage, looks very aerodynamic, almost like a Thirties air speed record contender?

  

Painting and markings:

This is where the real trouble came to play. It took a while to find a suitable/authentic paint scheme for a pre-WWII Lithuanian aircraft, and I took inspiration from mid-Thirties Letov S.20 biplane fighters and the real ANBO VIII light bomber prototype. Apparently, a two-tone camouflage in two shades of green were an option, even though the tones appear debatable. The only real-life reference was a b/w picture of an S.20, and it showed a good contrast between the greens, so that my first choice were Humbrol 120 (FS 34227) and 172 (Satin Dark Green). However: 120 turned out to be much too pale, and the 172 had a somewhat grainy consistency. Leaving a horrible finish on the already less-than-perfect PSR mess of the model.

 

With a heavy heart I eventually decided to remove the initial coat of enamel paint with a two-day bath in foamed oven cleaner, which did the job but also worked on the putty. Disaster struck when one wing came loose while cleaning the model, and the canopy came off, too…

Repairs were possible, but did not improve the model’s surface finish – but I eventually pulled a second coat of paint through, this time with slightly different green tones: a mix of Humbrol 80 (Grass Green) and Revell 360 (fern Green), resulting in a rich but rather yellow-ish tone, and Humbrol 245 (RLM 75, Graugrün), as a subdued contrast. The result, though, reminded a lot of Finnish WWII aircraft, so that I gave the aircraft an NMF cowling (again inspired by the ANBO VIII prototype) and a very light grey (Modelmaster 2077, RLM 63) underside with a low waterline. This gave the model a somewhat Italian touch?

 

The national markings came from two different Blue Rider decal sheets for modern Lithuanian aircraft, the tactical code and the knight helmet as squadron emblem came from a French Dewoitine D.520 (PrintScale sheet).

 

After a black ink washing the kit received light panel post-shading to virtually restore some of the missing surface details, some weathering with Tamiya Smoke and silver was done and the model received a final overall coat of matt acrylic varnish.

  

Well, I am not happy with the outcome – mostly because of the painting mishaps and the resulting collateral damage overall. However, the kitbashed aircraft looks pretty conclusive and plays the role of one of the many European pre-WWII monoplane fighters with modern features like a retractable landing gear and a closed canopy well, it’s a very subtle result.

 

+++ DISCLAIMER +++

BEWARE: nothing you see here is real, even though many conversions and their respective background stories were built upon historical facts.

 

The Messerschmitt Me 510 was a further development of the Me 410 Hornisse ("Hornet"), a German heavy fighter and Schnellbomber used by the Luftwaffe during World War II. The 410 itself had a troubled start, because it essentially had only been a straightforward modification of the Me 210, which had suffered from serious stability flaws and had a bad reputation among its crews.

 

The 410 handled bettr but did not show much improvement in performance, though. Me 410 deliveries began in January 1943, two years later than the original plan had called for, and continued until September 1944, by which point a total of 1.160 of all versions had been produced by Messerschmitt Augsburg and Dornier München. When it arrived, it was liked by its crews, even though its performance was not enough to protect it from the swarms of high performance allied fighters they faced.

 

Still not giving up on the original construction (and with the jigs and tools still available), Messerschmitt started in early 1944 with research into further means of improving the Me 410's performance. One direction was the addition of one or two jets under the fuselage as boosters for combat situations.

Another design path, which eventually led to the Me 510, was the development of turboprop and compound engines as propulsion options, which were based on the respective pure jet engines but offered much better performance and fuel economy than the pure jets. It would also be the more efficient solution compared to added turbojets for pure piston planes, since no dead weight had to be carried, and the overall system was less complex than a mixed powerplant system.

 

This turboprop concept, as best compromise between performance and short-term readiness for service, was chosen and the modified aircraft, called Messerschmitt Me 510, came to be. The design target was to outperform the Me 410 with as little change to the overall construction as possible, so that old tooling could be used for new aircraft cells. Alternatively, old aircraft should potentially be converted to the improved standard.

 

Core of the new development was the compact HeS 021 turboprop, a PTL development of the HeS 011 jet engine which was also planned for Focke Wulfs FW P.0310226-127 fighter (a turboprop version of the light 'Flitzer' day fighter). This engine was theoretically to deliver up to 3.300hp (2.426 kw) shaft output, plus 1.100kg (2.424 lb) additional thrust, even though serial types would produce less power under the aspect of reliability.

 

In order to incorporate this engine into the modified Me 410 a new main wing with laminar profile and new engine nacelles had to be designed. The HeS 021sat in the front part of the engine nacelles above the wings, driving four-bladed propellers. The landing gear retracted into the nacelle's lower section, rotating 90°, much like the Me 410, with the exhaust running above the landing gear wells.

 

In order to improve directional stability further, the tail surfaces were slightly enlarged, receiving characteristic, square tips. The fuselage was more or less taken from the original Me 410, since it offered a very good field of view and appropriate aerodynamics. With this package, the idea of retrofitting former Me 410 cells was kept, even though later flight tests showed that some more detail modifications had to be made. Most of these concerned the internal structures, the most obvious external change was the nose section, where the original glazing had to be reinforced and finally replaced by solid material – an experience similar to the modification from Douglas’ piston-driven XB-42 to the faster, jet-driven XB-43 of the same era.

 

Maiden flight of the first prototype took place in Augsburg on 6th of May 1945, with little problems. As benchmark, the Me 410's maximum speed was 625 km/h (388 mph), a cruise speed of 579 km/h (360 mph) and a combat range of 2.300 km (1,400 mi) with up to 1.000 kg (2,204 lbs) of disposable stores carried in- and externally.

 

The overall flying characteristics of the Me 410 did not change much, but rate of climb and top speed were considerably improved. In level flight, the third prototype Me 510 V3 reached a top speed of 812 km/h (504 mph), and even the serial version with added armament and equipment easily reached 750 km/h (465 mph) top speed and a cruising speed with no external stores of 650 km/h (405 mph). At its time, the Me 510, which quickly received the rather inofficial nickname "Bremse" (Horsefly), was superior to its pure piston engine and turbojet rivals, even though it was clear that the turboprop was only a preliminary solution.

 

Due to its high speed and under the pressure of Allied bomber raids, the Me 510 was primarily used as a Zerstörer against daylight bombers. Many aircraft received additional weapons, both directly incorporated at the factory but also as field accessories. Popular modifications included two extra 30mm guns (MK 108 or 103) in the bomb bay, or provisions for guided and unguided air to air missiles. A camera equipment package (Rüstsatz 'U3') allowed the fast aircraft to be used for daylight reconnaissance.

 

Many equipment packages from the earlier Me 410 could be fitted, too, including the massive 50mm BK 5 auto cannon against allied bomber groups. Initially, this package (‘U4’ Rüstsatz) comprised the original autocannon which fired at 45 RPM, with 21 shells in a drum magazine.

 

This weapon soon was replaced by the even more effective MK 214 B gun of 55mm caliber (Rüstsatz 'U5'). The BK 214 B fired at 180 RPM and proved to be a highly effective weapon at long ranges, outside of the bombers’ defensive armament range. As a drawback the heavy system (the gun plus the ammunition belt with 96 shells weighed 1.124 kg/2.475 lb) filled the whole internal bomb bay and precluded heavy external stores. Therefore, the 13mm machine guns in the nose were frequently removed in order to save weight, sometimes the weapons in the side barbettes, too. But: a single hit with one of the 1.54kg (3.4 lb) shells was enough to bring down a four-engined bomber, so that the fast Me 510 with this weapon became a serious threat in the course of late 1946.

The kit and its assembly:

I am not certain when inspiration struck me for this fantasy aircraft - I guess it was when I tinkered together the Hü 324 whif, which was itself based on a 1:72 scale Il-28 bomber. When I browsed for a respective donation kit I also came across the 1:100 scale kit of the Soviet light bomber from Tamiya, and that stirred something: The Il-28's vintage contours would perfectly suit a Luft '46 aircraft, and with some calculations it was clear that the 1:100 wings would be suitable for something in the class of a 1:72 DH Mosquito or Bf 110. Then, the ill-fated Me 410 came to the scene as a potential late war basis aircraft, and from this starting point the idea of an evolutionary next step of the type, the Messerschmitt Me 510, was born.

 

Basically this model is a kitbashing of a Tamiya Il-28 in 1:100 (wings & engine nacelles) and the fuselage of a Matchbox Me 410. The IL-28's wings were turned upside down, so that the nacelles would now ride on the wings' top.

This not only looks cool and 'different', it's also plausible because the landing gear could retract into the wings under the nacelles (with the main landing gear doors closed, just like the original Me 410), it would also reduce the angle of the aircraft on the ground to a sensible degree - with the engines under the wings plus the landing gear would have been much to steep!

 

Fitting the wings to the fuselage was pretty easy, even though the original Me 410 wing profile was much thicker than the slender Il-28 wings. Cleaning and blending the wing root areas was a bit tricky, but the parts get together well.

 

As a design twist and for a uniform look I also replaced the whole tail section, matching the angular look of the thin new main wings. The horizontal stabilizers are wing tips from a Matchbox Me 262, the vertical fin is a modified outer wing part from a Matchbox Grumman Panther.

 

The engine nacelles were taken OOB. I just filled the Il-28's landing gear wells and their covers with putty, since they'd end on top of the new engines.

 

The propellers come from Matchbox P-51 Mustangs, outfitted with pointed spinners and held by a metal pin in a polystyrene tube which runs through the original intake splitter. Looks pretty martial, even though the nacelles ended up a bit close to the fuselage. The overall look reminds of the Short Sturgeon, but is not inplausible. A compact aircraft!

 

The cockpit received some side panels, news seats and some equipment, since the original Matchbox kit features almost nothing beyond a floor plate, two broad benches as seats and pilot figures. I also opened the cockpit hatches, since the aircraft would be built for ground display, with the landing gear extended.

 

From the original kit the BK 5 cannon installation was taken over, but I added a scratch-built, bigger muzzle brake. Since the aircraft was to become a high speed interceptor/Zerstörer for daylight operations, I did not add any further external ordnance.

  

Painting and markings:

I pondered about a potential livery for a long time. Almost any Me 410 was delivered in RLM 74/75/76 livery, and some at the Western front in France were operated in RLM 70/71/65, with a low waterline. But I found this pretty... boring. So I made up a fantasy livery which I found suitable for high altitude operations and based on my knowledge of late Luftwaffe paint scheme - pretty complex:

 

The aircraft was to be light in color, primarily camouflaged for aerial combat. I ended up with something that was planned as something that could have almost been called 'low-viz': all lower surfaces received a basic tone of RLM 76 (from Testors), with a raised waterline on all flanks. This light blue-grey would blend into a slightly darker FS 36320 on the higher flanks, almost up to the upper surfaces.

 

But in the end, the flanks received more spots than intended, and I ended up with a rather conservative livery - but it ain't bad at all. But so it goes...

 

The upper wing surfaces received a wavy scheme in RLM 71 (Drak Green) and 75 (Middel Grey). These are not typical late war colors, I rather used them due to the lighter shades. On the fuselage, just the fuselage crest was painted with more or less dense blotches of these tones, blending into more patches of RLM 02 on the flanks.

 

To add some more unconventional detail, the fuselage sides and undersides also received large, cloudy patches of RLM 77 - a very light grey. This detail was featured on some late-war He 177 bombers, but you can hardly tell these extra blotches because they have only little contrast to the RLM 76.

 

The tail fin was painted all white - a formation sign for a squadron leader, typical for German late WWII fighters. The black and white fuselage stripe is the ID of Jagdgeschwader 26 (which operated Fw 190D-9 from airfields in northern Germany, Flensburg was one of them), the red number abd the "+" code identify the machine as being part of the eighth Staffel.

 

In the end, a very subtle whif. The new engines are most obvious, and they change the look of the Me 410 dramatically. But only on second glance you recognize the other changes. The new wings/stabilizers with their square-shaped tips create a very slender and elegant look, the aircraft just looks fast and agile like a true heavy fighter should. Mission accomplished!

Some background:

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

 

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

 

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

 

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

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

 

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

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

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

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

 

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

 

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

 

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

The model and its assembly:

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

 

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

 

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

 

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

 

Painting and markings:

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

 

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

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

  

Some background:

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

 

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

 

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

 

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

 

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

 

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

 

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

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

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

 

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

The kit and its assembly:

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

 

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

 

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

 

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

  

Painting and markings:

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

 

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

 

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

 

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

 

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

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

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

  

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

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

The kit and its assembly:

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

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

 

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

 

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

 

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

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

 

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

 

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

 

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

 

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

 

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

  

Painting and markings:

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

 

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

 

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

 

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

 

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

 

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

  

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

Some background:

The Douglas F3D Skyknight (later designated F-10 Skyknight) was a United States twin-engined, mid-wing jet fighter aircraft manufactured by the Douglas Aircraft Company in El Segundo, California. The F3D was designed as a carrier-based all-weather night fighter and saw service with the United States Navy and United States Marine Corps. The mission of the F3D-2 was to search out and destroy enemy aircraft at night.

 

The F3D was not intended to be a typical sleek and nimble dogfighter, but as a standoff night fighter, packing a powerful radar system and a second crew member. It originated in 1945 with a US Navy requirement for a jet-powered, radar-equipped, carrier-based night fighter. The Douglas team led by Ed Heinemann designed around the bulky air intercept radar systems of the time, with side-by-side seating for the pilot and radar operator. The result was an aircraft with a wide, deep, and roomy fuselage. Instead of ejection seats, an escape tunnel was used.

 

As a night fighter that was not expected to be as fast as smaller daylight fighters, the expectation was to have a stable platform for its radar system and the four 20 mm cannon mounted in the lower fuselage. The F3D was, however, able to outturn a MiG-15 in an inside circle. The fire control system in the F3D-1 was the Westinghouse AN/APQ-35.

The AN/APQ-35 was advanced for the time, a combination of three different radars, each performing separate functions: an AN/APS-21 search radar, an AN/APG-26 tracking radar, both located in the nose, and an AN/APS-28 tail warning radar. The complexity of this vacuum tube-based radar system, which was produced before the advent of semiconductor electronics, required intensive maintenance to keep it operating properly.

 

The F3D Skyknight was never produced in great numbers but it did achieve many firsts in its role as a night fighter over Korea. While it never achieved the fame of the North American F-86 Sabre, it did down several Soviet-built MiG-15s as a night fighter over Korea with only one air-to-air loss of its own against a Chinese MiG-15 on the night of 29 May 1953.

 

In the years after the Korean War, the F3D was gradually replaced by more powerful aircraft with better radar systems. The F3D's career was not over though; its stability and spacious fuselage made it easily adaptable to other roles. The Skyknight played an important role in the development of the radar-guided AIM-7 Sparrow missile in the 1950s which led to further guided air-to-air missile developments.

In 1954, the F3D-2M was the first U.S. Navy jet aircraft to be fitted with an operational air-to-air missile: the Sparrow I,an all weather day/night BVR missile that used beam riding guidance for the aircrew to control the flight of the missile. Only 38 aircraft (12 F3D-1Ms, and 16 F3D-2Ms) were modified to use the missiles, though.

 

One of the F3D's main flaws, which it shared with many early jet aircraft, was its lack of power and performance. Douglas tried to mend this through a radical redesign: The resulting F3D-3 was the designation assigned to a swept-winged version (36° sweep at quarter chord) of the Skyknight. It was originally to be powered by the J46 turbojet, rated at 4.080 lbf for takeoff, which was under development but suffered serious trouble.

 

This led to the cancellation of the J46, and calculated performance of the F3D-3 with the substitute J34 was deemed insufficient. As an alternative the aircraft had to be modified to carry two larger and longer J47-GE-2 engines, which also powered the USN's FJ-2 "Fury" fighter.

This engine's thrust of 6.000 pounds-force (27 kN) at 7,950 rpm appeared sufficient for the heavy, swept-wing aircraft, and in 1954 an order for 287 production F3D-3s was issued, right time to upgrade the new type with the Sparrow I.

 

While the F3D-3's outline resembled that of its straight wing predecessors, a lot of structural changes had to be made to accommodate the shifted main wing spar, and the heavy radar equipment also took its toll: the gross weight climbed by more than 3 tons, and as a result much of the gained performance through the stronger engines and the swept wings was eaten away.

 

Maximum internal fuel load was 1.350 US gallons, plus a further 300 in underwing drop tanks. Overall wing surface remained the same, but the swept wing surfaces reduced the wing span.

In the end, thrust-to-weight ratio was only marginally improved and in fact, the F3D-3 had a lower rate of climb than the F3D-2, its top speed at height was only marginally higher, and stall speed climbed by more than 30 mph, making carrier landings more complicated.

 

It's equipment was also the same - the AN/APQ-35 was still fitted, but mainly because the large radar dish offered the largest detection range of any carrier-borne type of that time, and better radars that could match this performance were still under construction. Anyway, the F3D-3 was able to carry Sparrow I from the start, and this would soon be upgraded to Sparrow III (which became the AIM-7), and it showed much better flight characteristics at medium altitude.

 

Despite the ,many shortcomings the "new" aircraft represented an overall improvement over the F3D-2 and was accepted for service. Production of the F3D-3 started in 1955, but technology advanced quickly and a serious competitor with supersonic capability appeared with the McDonnell F3H Demon and the F4D Skyray - much more potent aircraft that the USN immediately preferred to the slow F3Ds. As a consequence, the production contract was cut down to only 102 aircraft.

 

But it came even worse: production of the swept wing Skyknight already ceased after 18 months and 71 completed airframes. Ironically, the F3D-3's successor, the F3H and its J40 engine, turned out to be more capricious than expected, which delayed the Demon's service introduction and seriously hampered its performance, so that the F3D-3 kept its all weather/night fighter role until 1960, and was eventually taken out of service in 1964 when the first F-4 Phantom II fighters appeared in USN service.

 

In 1962 all F3D versions were re-designated into F-10, the swept wing F3D-3 became the F-10C. The straight wing versions were used as trainers and also served as an electronic warfare platform into the Vietnam War as a precursor to the EA-6A Intruder and EA-6B Prowler, while the swept-wing fighters were completely retired as their performance and mission equipment had been outdated. The last F-10C flew in 1965.

The kit and its assembly:

Another project which had been on the list for some years now but finally entered the hardware stage. The F3D itself is already a more or less forgotten aircraft, and there are only a few kits available - there has been a vacu kit, the Matchbox offering and lately kits in 1:72 and 1:48 by Sword.

 

The swept wing F3D-3 remained on the drawing board, but would have been a very attractive evolution of the tubby Skyknight. In fact, the swept surfaces resemble those of the A3D/B-66 a Iot, and this was the spark that started the attempt to build this aircraft as a model through a kitbash.

 

This model is basically the Matchbox F3D coupled with wings from an Italeri B-66, even though, being much bigger, these had to be modified.

 

The whole new tail is based on B-66 material. The fin's chord was shortened, though, and a new leading edge (with its beautiful curvature) had to be sculpted from 2C putty. The vertical stabilizers also come from the B-66, its span was adjusted to the Skyknight's and a new root intersection was created from styrene and putty, so that a cross-shaped tail could be realized.

The tail radar dish was retained, even though sketches show the F3D-3 without it.

 

The wings were take 1:1 from the B-66 and match well. They just had to be shortened, I set the cut at maybe 5mm outwards of the engine pods' attachment points. They needed some re-engraving for the inner flaps, as these would touch the F3D-3's engines when lowered, but shape, depth and size are very good for the conversion.

 

On the fuselage, the wings' original "attachment bays" had to be filled, and the new wings needed a new position much further forward, directly behind the cockpit, in order to keep the CoG.

 

One big issue would be the main landing gear. On the straight wing aircraft it retracts outwards, and I kept this arrangement. No detail of the exact landing gear well position was available to me, so I used the Matchbox parts as stencils and placed the new wells as much aft as possible, cutting out new openings from the B-66 wings.

The OOB landing gear was retained, but I added some structure to the landing gear wells with plastic blister material - not to be realistic, just for the effect. A lot of lead was added in the kit's nose section, making sure it actually stands on the front wheel.

 

The Matchbox Skyknight basically offers no real problems, even though the air intake design leaves, by tendency some ugly seams and even gaps. I slightly pimped the cockpit with headrests, additional gauges and a gunsight, as well as two (half) pilot figures. I did not plan to present the opened cockpit and the bulbous windows do not allow a clear view onto the inside anyway, so this job was only basically done. In fact, the pilots don't have a lower body at all...

 

Ordnance comprises of four Sparrow III - the Sparrow I with its pointed nose could have been an option, too, but I think at the time of 1960 the early version was already phased out?

   

Painting and markings:

This was supposed to become a typical USN service aircraft of the 60ies, so a grey/white livery was predetermined. I had built an EF-10B many years ago from the Matchbox kit, and the grey/white guise suits the Whale well - and here it would look even better, with the new, elegant wings.

 

For easy painting I used semi matt white from the rattle can on the lower sides (painting the landing gear at the same time!), and then added FS 36440 (Light Gull Grey, Humbrol 129) with a brush to the upper sides. The radar nose became semi matt black (with some weathering), while the RHAWS dish was kept in tan (Humbrol 71).

 

In order to emphasize the landing gear and the respective wells I added a red rim to the covers.

The cockpit interior was painted in dark grey - another factor which made adding too many details there futile, too...

 

The aircraft's individual marking were to be authentic, and not flamboyant. In the mid 50ies the USN machines were not as colorful as in the Vietnam War era, that just started towards the 60ies.

 

The markings I used come primarily from an Emhar F3H Demon, which features no less than four(!) markings, all with different colors. I settled for a machine of VF-61 "Jolly Rogers", which operated from the USS Saratoga primarily in the Mediterranean from 1958 on - and shortly thereafter the unit was disbanded.

 

I took some of the Demon markings and modified them with very similar but somewhat more discrete markings from VMF-323, which flew FJ-4 at the time - both squadrons marked their aircraft with yellow diamonds on black background, and I had some leftover decals from a respective Xtradecal sheet in the stash.

  

IMHO a good result with the B-66 donation parts, even though I am not totally happy with the fin - it could have been more slender at the top, and with a longer, more elegant spine fillet, but for that the B-66 fin was just too thick. Anyway, I am not certain if anyone has ever built this aircraft? I would not call the F3D-3 elegant or beautiful, but the swept wings underline the fuselage's almost perfect teardrop shape, and the thing reminds a lot of the later Grumman A-6 Intruder?

Some background:

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 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!

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

The kit and its assembly:

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

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

 

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

 

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

 

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

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

 

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

 

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

 

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

 

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

 

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

  

Painting and markings:

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

 

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

 

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

 

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

 

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

 

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

  

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

Some background:

The Douglas F3D Skyknight (later designated F-10 Skyknight) was a United States twin-engined, mid-wing jet fighter aircraft manufactured by the Douglas Aircraft Company in El Segundo, California. The F3D was designed as a carrier-based all-weather night fighter and saw service with the United States Navy and United States Marine Corps. The mission of the F3D-2 was to search out and destroy enemy aircraft at night.

 

The F3D was not intended to be a typical sleek and nimble dogfighter, but as a standoff night fighter, packing a powerful radar system and a second crew member. It originated in 1945 with a US Navy requirement for a jet-powered, radar-equipped, carrier-based night fighter. The Douglas team led by Ed Heinemann designed around the bulky air intercept radar systems of the time, with side-by-side seating for the pilot and radar operator. The result was an aircraft with a wide, deep, and roomy fuselage. Instead of ejection seats, an escape tunnel was used.

 

As a night fighter that was not expected to be as fast as smaller daylight fighters, the expectation was to have a stable platform for its radar system and the four 20 mm cannon mounted in the lower fuselage. The F3D was, however, able to outturn a MiG-15 in an inside circle. The fire control system in the F3D-1 was the Westinghouse AN/APQ-35.

The AN/APQ-35 was advanced for the time, a combination of three different radars, each performing separate functions: an AN/APS-21 search radar, an AN/APG-26 tracking radar, both located in the nose, and an AN/APS-28 tail warning radar. The complexity of this vacuum tube-based radar system, which was produced before the advent of semiconductor electronics, required intensive maintenance to keep it operating properly.

 

The F3D Skyknight was never produced in great numbers but it did achieve many firsts in its role as a night fighter over Korea. While it never achieved the fame of the North American F-86 Sabre, it did down several Soviet-built MiG-15s as a night fighter over Korea with only one air-to-air loss of its own against a Chinese MiG-15 on the night of 29 May 1953.

 

In the years after the Korean War, the F3D was gradually replaced by more powerful aircraft with better radar systems. The F3D's career was not over though; its stability and spacious fuselage made it easily adaptable to other roles. The Skyknight played an important role in the development of the radar-guided AIM-7 Sparrow missile in the 1950s which led to further guided air-to-air missile developments.

In 1954, the F3D-2M was the first U.S. Navy jet aircraft to be fitted with an operational air-to-air missile: the Sparrow I,an all weather day/night BVR missile that used beam riding guidance for the aircrew to control the flight of the missile. Only 38 aircraft (12 F3D-1Ms, and 16 F3D-2Ms) were modified to use the missiles, though.

 

One of the F3D's main flaws, which it shared with many early jet aircraft, was its lack of power and performance. Douglas tried to mend this through a radical redesign: The resulting F3D-3 was the designation assigned to a swept-winged version (36° sweep at quarter chord) of the Skyknight. It was originally to be powered by the J46 turbojet, rated at 4.080 lbf for takeoff, which was under development but suffered serious trouble.

 

This led to the cancellation of the J46, and calculated performance of the F3D-3 with the substitute J34 was deemed insufficient. As an alternative the aircraft had to be modified to carry two larger and longer J47-GE-2 engines, which also powered the USN's FJ-2 "Fury" fighter.

This engine's thrust of 6.000 pounds-force (27 kN) at 7,950 rpm appeared sufficient for the heavy, swept-wing aircraft, and in 1954 an order for 287 production F3D-3s was issued, right time to upgrade the new type with the Sparrow I.

 

While the F3D-3's outline resembled that of its straight wing predecessors, a lot of structural changes had to be made to accommodate the shifted main wing spar, and the heavy radar equipment also took its toll: the gross weight climbed by more than 3 tons, and as a result much of the gained performance through the stronger engines and the swept wings was eaten away.

 

Maximum internal fuel load was 1.350 US gallons, plus a further 300 in underwing drop tanks. Overall wing surface remained the same, but the swept wing surfaces reduced the wing span.

In the end, thrust-to-weight ratio was only marginally improved and in fact, the F3D-3 had a lower rate of climb than the F3D-2, its top speed at height was only marginally higher, and stall speed climbed by more than 30 mph, making carrier landings more complicated.

 

It's equipment was also the same - the AN/APQ-35 was still fitted, but mainly because the large radar dish offered the largest detection range of any carrier-borne type of that time, and better radars that could match this performance were still under construction. Anyway, the F3D-3 was able to carry Sparrow I from the start, and this would soon be upgraded to Sparrow III (which became the AIM-7), and it showed much better flight characteristics at medium altitude.

 

Despite the ,many shortcomings the "new" aircraft represented an overall improvement over the F3D-2 and was accepted for service. Production of the F3D-3 started in 1955, but technology advanced quickly and a serious competitor with supersonic capability appeared with the McDonnell F3H Demon and the F4D Skyray - much more potent aircraft that the USN immediately preferred to the slow F3Ds. As a consequence, the production contract was cut down to only 102 aircraft.

 

But it came even worse: production of the swept wing Skyknight already ceased after 18 months and 71 completed airframes. Ironically, the F3D-3's successor, the F3H and its J40 engine, turned out to be more capricious than expected, which delayed the Demon's service introduction and seriously hampered its performance, so that the F3D-3 kept its all weather/night fighter role until 1960, and was eventually taken out of service in 1964 when the first F-4 Phantom II fighters appeared in USN service.

 

In 1962 all F3D versions were re-designated into F-10, the swept wing F3D-3 became the F-10C. The straight wing versions were used as trainers and also served as an electronic warfare platform into the Vietnam War as a precursor to the EA-6A Intruder and EA-6B Prowler, while the swept-wing fighters were completely retired as their performance and mission equipment had been outdated. The last F-10C flew in 1965.

The kit and its assembly:

Another project which had been on the list for some years now but finally entered the hardware stage. The F3D itself is already a more or less forgotten aircraft, and there are only a few kits available - there has been a vacu kit, the Matchbox offering and lately kits in 1:72 and 1:48 by Sword.

 

The swept wing F3D-3 remained on the drawing board, but would have been a very attractive evolution of the tubby Skyknight. In fact, the swept surfaces resemble those of the A3D/B-66 a Iot, and this was the spark that started the attempt to build this aircraft as a model through a kitbash.

 

This model is basically the Matchbox F3D coupled with wings from an Italeri B-66, even though, being much bigger, these had to be modified.

 

The whole new tail is based on B-66 material. The fin's chord was shortened, though, and a new leading edge (with its beautiful curvature) had to be sculpted from 2C putty. The vertical stabilizers also come from the B-66, its span was adjusted to the Skyknight's and a new root intersection was created from styrene and putty, so that a cross-shaped tail could be realized.

The tail radar dish was retained, even though sketches show the F3D-3 without it.

 

The wings were take 1:1 from the B-66 and match well. They just had to be shortened, I set the cut at maybe 5mm outwards of the engine pods' attachment points. They needed some re-engraving for the inner flaps, as these would touch the F3D-3's engines when lowered, but shape, depth and size are very good for the conversion.

 

On the fuselage, the wings' original "attachment bays" had to be filled, and the new wings needed a new position much further forward, directly behind the cockpit, in order to keep the CoG.

 

One big issue would be the main landing gear. On the straight wing aircraft it retracts outwards, and I kept this arrangement. No detail of the exact landing gear well position was available to me, so I used the Matchbox parts as stencils and placed the new wells as much aft as possible, cutting out new openings from the B-66 wings.

The OOB landing gear was retained, but I added some structure to the landing gear wells with plastic blister material - not to be realistic, just for the effect. A lot of lead was added in the kit's nose section, making sure it actually stands on the front wheel.

 

The Matchbox Skyknight basically offers no real problems, even though the air intake design leaves, by tendency some ugly seams and even gaps. I slightly pimped the cockpit with headrests, additional gauges and a gunsight, as well as two (half) pilot figures. I did not plan to present the opened cockpit and the bulbous windows do not allow a clear view onto the inside anyway, so this job was only basically done. In fact, the pilots don't have a lower body at all...

 

Ordnance comprises of four Sparrow III - the Sparrow I with its pointed nose could have been an option, too, but I think at the time of 1960 the early version was already phased out?

   

Painting and markings:

This was supposed to become a typical USN service aircraft of the 60ies, so a grey/white livery was predetermined. I had built an EF-10B many years ago from the Matchbox kit, and the grey/white guise suits the Whale well - and here it would look even better, with the new, elegant wings.

 

For easy painting I used semi matt white from the rattle can on the lower sides (painting the landing gear at the same time!), and then added FS 36440 (Light Gull Grey, Humbrol 129) with a brush to the upper sides. The radar nose became semi matt black (with some weathering), while the RHAWS dish was kept in tan (Humbrol 71).

 

In order to emphasize the landing gear and the respective wells I added a red rim to the covers.

The cockpit interior was painted in dark grey - another factor which made adding too many details there futile, too...

 

The aircraft's individual marking were to be authentic, and not flamboyant. In the mid 50ies the USN machines were not as colorful as in the Vietnam War era, that just started towards the 60ies.

 

The markings I used come primarily from an Emhar F3H Demon, which features no less than four(!) markings, all with different colors. I settled for a machine of VF-61 "Jolly Rogers", which operated from the USS Saratoga primarily in the Mediterranean from 1958 on - and shortly thereafter the unit was disbanded.

 

I took some of the Demon markings and modified them with very similar but somewhat more discrete markings from VMF-323, which flew FJ-4 at the time - both squadrons marked their aircraft with yellow diamonds on black background, and I had some leftover decals from a respective Xtradecal sheet in the stash.

  

IMHO a good result with the B-66 donation parts, even though I am not totally happy with the fin - it could have been more slender at the top, and with a longer, more elegant spine fillet, but for that the B-66 fin was just too thick. Anyway, I am not certain if anyone has ever built this aircraft? I would not call the F3D-3 elegant or beautiful, but the swept wings underline the fuselage's almost perfect teardrop shape, and the thing reminds a lot of the later Grumman A-6 Intruder?

Some background:

The mighty Suchoj SuCh-1 started its life in early March 1943, when the Sukhoi OKB finished work on the design of a high-speed fighter with a unique powerplant arrangement. The aircraft was an all-metal low-wing mono­plane with conventional tail surfaces. The three-section wings had constant dihedral and basically trapezoidal planform; the sta­bilizers had zero dihedral.

 

Two Klimov M-107 water-cooled Vee-12 engines, each with a. take-off power of 1 ,600 hp (1,193 kW) and a maximum design power of 1,500 hp (1,119 kW) at 5,500 m (18,045 ft), were mounted in the center fuse­lage in a staggered-tandem arrangement: the front engine was offset to starboard and of the rear one to port. Thus, the total power was increased but the drag was the same as for a single-engined aircraft, which was expected to increase fight speed consider­ably. Consequently, the project was internally designated 'I-2M107', literally "Article powered by two M107 engines".

 

Furthermore, the left cylinder bank of the front engine and the right cylinder bank of the rear engine were disposed vertically, so that each engine had one set of exhaust stubs on top of the fuselage and one on the fuselage side. Both engines drove a single three ­blade tractor propeller of 4.0 m (13 tt 2 in) diameter via parallel extension shafts and a common reduction gearbox. Both water radiators were located side by side in a chin housing, while the oil coolers were buried in the wings. The total fuel capacity of the four tanks arranged in the center fuselage was 1,113 litres (244.86 Imp. gal).

 

Because of the power plant arrangement and the large ground angle (necessary to give adequate ground clearance for the large propeller) the cockpit was offset to port and placed ahead of the wing leading edge to provide better forward visibility on take-off and landing. The cockpit was protected by a bulletproof windscreen, a front armor plate and an armored backrest; the armor weight totaled 70kg (154Ib).

 

The main landing gear units with 800 x 280 mm (31.5x11 in) wheels retracted inwards into the wing roots and the 400 x 150 mm (15.7 x 5.9 in) tail wheel retracted aft. The fighter's armament consisted of two wing-mounted 12.7-mm Berezin UBS machine-guns firing outside the propeller disc and a single 20-mm ShVAK cannon fir­ing through the propeller hub*.

 

A full-scale mock-up was inspected in December 1943, and with German long range bombers threatening the Western front line as well as the lack of a fast and powerful fighters to intercept them (the earlier MiG-5 had turned out to be a disappointment, and Mikoyan's I-211/221 family if high altitude fighters also suffered from serious technical problems at that time), OKB Suchoj received an immediate go-ahead for further development of the SuCh-1, how the I-2M107 was now officially called, since Vladimir A. Chizhevskiy took lead of the project.

 

In the course of 1944 three prototypes went through a fast development program. While the aircraft itself was easy to handle, overheating problems and trouble with the gearbox for the two engines could only partly be rectified - esp. the power transmission should remain the SuCh-1s Achilles Heel.

 

Anyway, the Su-5 was ready for service introduction towards late 1944, and the powerful type was exclusively to be used as an interceptor. Several improvements had been made, compared to the prototypes: now two slightly more powerful Klimov VK-107A engines were used, which were better suited for high altitude operations, and the chin-mounted water cooler was considerably enlarged. The oil coolers had been re-designed and they were now placed under the wing roots.

 

The wing span had been extended by 6' and a bigger (now 4.3m diameter!), four-bladed propeller was added in order to improve performance at high altitude. No pressurized cabin was installed, but the cockpit received an extended glazing for better all-round field of vision.

 

Armament had also been augmented: now a Nudelman N-23 23mm cannon was firing through the propeller hub, and the number of UBS machine-guns in the wings was increased to four.

 

As initial duty experience was gathered, it became quickly clear that the firepower had to be augmented, so that the propeller-hub-mounted 23mm cannon was quickly replaced by a Nudelman-Richter NR-37 37mm cannon, and the four wing-mounted UBS machine guns were replaced by two 20-mm ShVAK cannons or even two Nudelman N-23 23mm cannons - the latter became the production standard from March 1945 on, even though the type's designation did not change.

 

Experience also showed that the overheating problem had been cured, but the complicated gear box tended to malfunction, esp. when full power was called for in aerial combat: high G forces took their toll and damaged the bearings, even warping the extension shafts and structural parts, so that some SuCh-1 were literally torn apart in mid-air.

 

The high torque powers of the large propeller also took their toll on handling: starting and landing was described as "hazardous", esp. when the fuel tanks were empty or in cross winds.

Consequently, SuCh-1 pilots were warned to engage into any dogfight or enter close combat with single-engined enemy fighters, and just focus on large enemy aircraft.

 

On the other side, the SuCh-1's powerful cannon armament made it a deadly foe: a single hit with the NR-37 cannon could down an aircraft, and its top speed of roundabout 700 km/h (435 mph) was more than enough for the Luftwaffe's heavy bomber types like the He 177.

 

Several engine and armament experiments were undertaken. For instance, at least one SuCh-1 was outfitted with a Nudelman-Sooranov NS-45 45mm cannon firing through the propeller hub, even a 57mm cannon was envisaged. Furthermore, one airframe was prepared to carry two Charomskiy M-30V 12 cylinder diesel engines, in order to produce a heavy long-range escort fighter (internally called I-2M30V).

In order to minimize the torque problems a contraprop arrangement with two three-bladed propellers and a diameter of only 3.6m was under development.

 

All in all only 120 of these powerful machines were built until the end of hostilities, as the feared mass attacks of German long range bombers did not materialize. as the Su-7 was complicated to operate and jet engines promised a far more efficient way of propulsion for high speeds, the type was already retired in 1947 and replaced by 1st generation jet fighters like the Yak-15 and MiG-9, which carried a similar armament, attained a better performance (except for the range) but weighed only half of the large and heavy SuCh-1.

*Information about the conceptual Suchoj I-2M107 was primarily gathered from the book 'OKB Suchoj', written by Yefim Gordon & Dmitriy Komissarov; Hersham (UK), 2010.

.

 

The kit and its assembly (a long story!):

This abomination of an aircraft is/was real, even though the I-2M107 was never built – the fictional name Suchoj-Chizhevskiy SuCh-1 was actually chosen because I could not find any plausible Su-X code for a WWII fighter. Vladimir A. Chizhevskiy actually joined the Suchoj OKB in mid WWII, so I deemed this alternative to be plausible.

 

I had this on the agenda for a long time, but the horrors of kitbashing kept me from building it - until now. The current Anthony P memorial Group Build (for the deceased fellow member at whatifmodelers.com, RIP) was a good motivation to tackle this brute thing. Fortunately, I already had some major ingredients in store, so work could start asap.

 

From that, anything else was improvised from the scrap box, and with only a three side view of the I-2M107 as guidance. It became a true Frankenstein creation with...

 

● Fuselage and inner wings from the (horrible) NOVO Attacker

● Wings from an Italeri Fw 190 D-9 attached to them

● Nose is a resin Griffon from an Avro Lincoln conversion set from OzMods

● Tail cone is a radar nose from an F-4J Phantom II

● Tail fin is a horizontal stabilizer from a Matchbox SB2C Helldiver

● Vertical stabilizers come from a Matchbox Me 410

● Oil coolers are modified front landing gear wells from two Revell G.91 kits

● Cockpit hood comes from a Revell P-39 Airacobra

● Landing gear comes from an Italeri Fw 190 D-9, covers were modified/improvised

● Main wheels belong to a MPM Ryan Dark Shark

● Tail wheel belongs to a Matchbox Harrier

● The propeller was scratched, IIRC from a Grumman Hellcat drop tank front and blades from an Airfix A-1 Skyraider. Inside, a metal axis was mounted.

.

 

Work started with the fuselage and the wings as separate segments.

 

The Attacker fuselage lost its fin and the cockpit and air intakes were simply cut away, just as the tail pipe. The resin Griffon was slightly shortened at the front, but more or less directly attached to the fuselage, after I had cut out openings for the four rows of exhaust nozzles.

Then, the new tail cone was glued onto the end and the original fairings for the Attacker's stabilizer cut away and sanded even - anything had to be made new.

 

The wings were a bit tricky. I had hoped to use the Attacker's OOB wings, but these were not only much too small and did not have the proper shape, they also lacked landing gear wells!

 

Finding a solution was not easy, and I had to improvise. After some trials I decided to cut the Attacker wing span at about the width where the guns are located, and then add Fw 190 wings.

The depth would be fine, even though the Fw 190 wings were a bit thicker, and they offered a leading edge kink which was good for the original and characteristic I-2M107's wing root extensions. The latter were sculpted from a 6mm thick core or styrene sheet, added to the Attacker parts' leading edge, and the rest, as well as the lacking Attacker wing's thickness, sculpted with 2C and later NC putty.

 

Furthermore I cut out and sculpted landing gear wells, another challenging, since these had to cover the Attacker/Fw 190 parts' intersection! LOTS of putty work, sanding and shaving, but as a benefit I was able to use the Attacker kit's original wing/fuselage joints. Effectively, my placement turned out to be a bit far outside, so the track appears too wide - the price to pay when you work on single parts. Anyway, I left it was it turned out, as a major correction at a late working stage would mean to tear anything apart again...

 

Back to the nose: adding the propeller and the cockpit into the massive nose was the next working station. The propeller had to be huge, and also needed a rather big spinner. A contraprop was ruled out, even though it would have looked great here. But eventually I settled for a scratch-built thing, made from a teardrop-shaped drop tank front onto which the four blades from a A-1 Skyraider were glued. Probably the biggest prop I have ever put onto a 1:72 scale model! Since the resin nose was massive, drilling a hole and adding a metal axis to the propeller was enough.

 

With that in place I started carving out a cockpit opening - it worked better and easier than expected with a mini drill and a coarse shaving head! The opening is still rather small, a seat and a pilot hardly fit, but it works - I found a rather smallish pilot figure, and added a seat and some other small details from the scrap box, just to have something inside.

 

For a canopy I found a very old (30 years, I guess...) clear part from a Revell P-39 Airacobra in the scrap box, which was almost perfect in shape and width. It was a bit blind and stained with ancient enamel paint, but some wet sanding and serious polishing almost got it back to translucent status. Since I would not open the cockpit, this was a sufficient solution.

 

The asymmetrical cockpit opening was, in an initial step, faired with styrene strips, for a rough outline, and then sculpted with 2C and later NC putty, blending it into the rest of the fuselage.

 

For the tail surfaces, the SB2C stabilizer was cut away at its base - it is not a bad donation piece, its shape and rudder come pretty close to the I-2M107's original design!

The stabilizers I used on my kitbash come from a Me 410, and their leading edge was a cut away so that the sweep angle would be a bit larger. They lack depth, compared to the I-2M107's original design, but since the wings have become more slender, too, I think it's a good compromise, and the best what I had at hand in the spares stash.

 

Finally, and before detail work could start, the wings were attached to the fuselage. I eventually set them back by ~6mm, so that the new, extended leading edge would match the respective fairing on the fuselage. The resulting gap at the trailing edge was, again, filled with 2C and NC putty.

 

A personal change was a different oil cooler arrangement. The original location was to be in the wings' leading edge, just in front of the landing gear wells - but that appeared a bit doubtful, as I could not find a plausible solution where the exit for the air would be? Consequently, and in order to avoid even more messy putty sculpting on the wings, I decided to re-locate the oil coolers completely, into shallow, tunnel-like fairings under the wing roots, not unlike the radiator arrangement on a Spitfire or Bf 109.

 

In order to check the surface quality I decided to add a coat of grey primer, once the fuselage/wing segments had been connected. This showed only minor flaws, but made another turn with NC putty and wet sanding necessary.

 

Now it was time for finishing touches, e .g. mounting the landing gear, completing the cockpit and adding exhaust stubs - cut individually from HO scale model railroad roof tiles and inserted into the four fuselage fairings.

 

The canopy was fixed into place with white glue, which also helped closing some small gaps.

.

 

Painting and markings:

While the I-2M107 looks odd, to say the least, I wanted to keep the paint scheme rather simple and quasi-authentic. I went for a pale grey/green camouflage, used e. g. on late war Yakovlev Yak-3 fighters.

 

Basic colors are Humbrol 31 (Slate Grey, it has a very greenish, even teal, hue), ModelMaster 1740 (Dark Gull Grey, FS 36231) and Humbrol 167 (Barley Grey) for the lower sides with a wavy waterline. Since only marginal surface details were left over, I decided to fake panels and panel lines with paint.

Panels were simulated with lighter shades of the basic tones (RLM 62 from ModelMaster, Humbrol 140 and 127 below), panel lines were painted with highly thinned grey acrylic paint and a special brush - in German it's called a 'Schlepppinsel', it's got very long hairs and is also used to paint scallops on car models, and similar things are used for real car tuning/custom paintwork, too.

Sure, the painted panel lines are a bit rough, but I did not want to risk any damage through manual engraving on the rather delicate mixed-media surface of the kitbashed model. For an overall look or first impression it's very good, though.

 

As 'highlights' I added a white spinner and half of the fin was painted white, too.

 

The decals were puzzled together. The flashes and the tactical code number come from a Hobby Boss La-7, the Red Stars, IIRC, belong to a vintage MiG-21F from Hasegawa. The "Rodinu" slogan actually belongs to a 1:35 Soviet Tank decals set.

 

Finally, after some additional dry painting with light grey, some oil stains around the engines and coolers and soot stains at the exhaust stubs and guns (painted, plus some grinded graphite, as it yields a nice, metallic shimmer that looks like oil or burnt metal), everything was sealed under a coat of matt acrylic varnish.

  

If it had been built, the Suchoj I-2M107 must have been an impressive aircraft - it was bigger than a P-47 Thunderbolt or an A-1 Skyraider, and one can only wonder how its field performance would have been?

Similar concepts had been underway in UK, too, e. g. for a heavy naval attack aircraft, but the I-2M107 with its asymmetrical cockpit and engine arrangement were unique. A worthy whif, even if some details like the landing gear or the borrowed nose section are not 100% 'correct'.

Some background:

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

 

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

 

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

 

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

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

 

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

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

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

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

 

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

 

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

 

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

4x12 micro missiles in four HMMP-02 micro-missile launchers, one inside each booster pod

  

The model and its assembly:

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

 

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

 

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

 

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

 

Painting and markings:

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

 

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

 

+++ DISCLAIMER +++

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

  

Some background:

The 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:

Instead of a story compiled/edited by myself, a very good “real” source: an article about the “American Spirit” project from 1996, scanned from a magazine and posted elsewhere:

hanksnet.com/images/as_p1.jpg

hanksnet.com/images/as_p2.jpg

hanksnet.com/images/as_p3.jpg

hanksnet.com/images/as_p4.jpg

 

This and some more information, including a drawing of the (apparently never) finished aircraft and a photo of the semi-finished airframe on airliners.net were the basis for my build.

  

The kit and its assembly:

This is my third and last entry to the “Racing” group build at whatifmodelers.com that ended in Feb. 2019. It is nothing less than the attempt to re-create the potentially fastest piston engine aircraft in the world as a model, based on the sparse information I was able to gather (see above). The aircraft’s design is quite odd, and it is worth reading the design background in the article, because it was a true “garage build” with the intention to use as many existing components in order to save costs and development time.

 

This was, more or less, mirrored during the building process, and like the real “American Spirit” the model consists at its core of a Matchbox T-2 “Buckeye” jet trainer! The T-2 fuselage lost its nose section, the ventral engine bay and the original cockpit fairing. This left a lot of fuselage surface to be re-constructed. The fin was clipped, too, just like in real life. At the fin’s base I added a cockpit opening and implanted a cockpit tub, taken from a Revell G.91. A new bucket seat (probably from an Academy Fw 190) was installed, and a new, tight canopy – I think it originally came from a Revell Go 229, but it was trimmed down considerably to match the T-2’s fuselage lines. The canopy was blended into the fin root with massive 2C putty sculpting, and the area in front of the windscreen was created with 2C putty, too. Both a tedious PSR process.

 

Once the upper fuselage shape was finished I started searching for a cowling and a matching propeller. After several attempts with bigger engines (e. g. from a Super Constellation) I eventually settled upon a rather narrow (but bleak) cowling from an Pioneer2/Airfix Hawker Sea Fury, which turned out to have just the right diameter for the re-constructed T-2 fuselage and matched the “American Spirit” drawing’s well.

It also had at the front end the right diameter for the propeller: it comes, just like in real life, from a C-130 Hercules, even though I used a late variant with six blades, a resin aftermarket piece, taken from an Attack Squadron engine nacelle set. Unfortunately, the spinners were molded onto the engines, so that I had to cut my donor part away. Three of the six propeller blade attachment points were faired over. While the original “American Spirit” carried clipped blades from an Electra airliner, I used parts from a P-3 Orion – the come very close in shape and size, and were easy to install. Finally, the propeller received a metal axis and a matching styrene tube adapter in the Sea Fury cowling.

 

Once the engine was in place, the cowling was filled with as much lead as possible, since the model would be built with an extended landing gear.

However, a large ventral section was still missing, and it was created with a leftover underwater section from a model ship hull, and lots of more putty, of course. A small tail bumper was added under the fin.

 

Once the fuselage was more or less finished, I turned my attention to the wings and stabilizers. The latter were supposed to be “un-swept F-86H stabilizers”, but unfortunately I could not find visual evidence of what this would have looked like. I tried some donor parts, including stabilizers from an F-86A and D, as well as from a MiG-15, and eventually decided to use individual parts, because nothing looked convincing to me, either swept or straight. Actually the MiG-15 parts looked the best, but they were too small, so I used the wings from an 1:144 Panavia Tornado (Dragon) and tailored them into a sweep angle similar to the MiG-15 parts, but with more depth and span. Not certain how “realistic” this is, but it looks good and compliments the swept T-2 fin well.

 

The T-2 wings saw only minor modifications: the wing tip tanks were cut off and the tips as well as the flaps faired over, since the “American Spirit” did not feature the latter anymore. The small LERXs were cut away, too, and instead I added small air intakes – the “American Spirit” probably did not feature them, but I wondered where the aircraft’s engine would feed its carburetor or an oil cooler? The respective gaps on the fuselage flanks were filled accordingly.

 

Some more work waited on the fuselage, too. The aircraft’s drawing showed shallow openings on the forward fuselage’s flanks, but their function was not clear – I assume that the exhausts from the 18 cylinder engine were collected there, 9 on each side, so I carved the openings into the massive plastic and putty fuselage with a mini drill tool and added exhaust stubs as well as deflector plates.

Another issue was the well for the front landing gear – this came, together with the complete front leg, from an Italeri F-100, just like in real life. The good thing about the Italeri kit is that it comes with a separate well tub, which made the installation quite easy. I just cut a square section out of the lower fuselage behind the engine and the landing gear well snuggly fell into place, with only little PSR effort. And, to my surprise, the end result seems to be a very good match to the real life design – even though I was not able to confirm this with picture material.

 

The main landing gear was taken OOB from the Matchbox T-2 – and it is really a weird sight, since the T-2’s track is very wide while the wheelbase is unusually short. But the source article indicates that this must have been the designers’ plans!

  

Painting and markings:

While the model’s hardware came quite close to the real thing, the livery of the “American Spirit” was totally open, so I created my own. I felt that two design directions would be appropriate: either a relatively dry and clean design, e. g. in overall silver or white with a little trim, or something patriotic, reflecting the aircraft’s name.

I eventually settled for the latter, and considered several approaches in white, red and blue, and eventually settled for one of my first ideas, a kind of “flying American flag” in an asymmetrical design, somewhat inspired by a Bicentennial F-106A from 1976: this machine carried a white fuselage with some red trim stripes and a blue nose section that featured lots of tiny white stars. I took this layout a little further and gave the “American Spirit” a dark blue engine cowling and front fuselage section, as well as a single blue wing. From that, wide red and white stripes stream backwards across the other wing, the fuselage and the tail. The design was mirrored on the undersides.

The stripes were painted with a wide brush with Humbrol 19 and 22, after the kit had been primed with white and had received an overall white basic coat with acrylic paint from the rattle can, too. The blue section was painted with Revell 350 (RAL 5013/Lufthansa Blue). I tried to add some “wavy flag texture” effect to the basic paints with slightly different tones, added wet-in-wet to the basic paints, but the visual effect turned out to be minimal, so I left it like that.

 

The stars are all individual waterslide decals, coming from an 1:87 Allied WWII markings sheet from TL Modellbau. The big white stars that are the background for the starting numbers on top and below the blue wing come from an 1:72 F4U. The red and blue starting numbers themselves were taken from a TL Modellbau sheet for firefighting vehicles: they are actually parts of German emergency telephone numbers…

 

Some stencils and leading edges on all wings, created with generic silver decal material, completed the outside, and finally I painted some fake panel lines onto the hull with a soft pencil. The T-2 air brakes, which were retained for the “American Spirit”, were re-created with fine black decal lines. Similar material in silver was used to simulate panel lines for the cooling air outlet flaps on the cowling. Unfortunately, the T-2 kit itself did not come with much surface detail, and any leftover rest (like the air brakes) disappeared during the extensive PSR sessions and under the primer and paint coats. Finally, the kit was sealed with a coat of semi-gloss acrylic varnish (Italeri).

  

A massive scratch-build. While challenging the work on this model was fun because it followed in its creation a similar process as the real “American Spirit”, which was, AFAIK, sold and never completed. In the end, I am positively surprised how close the overall outlines seem to come to the real (and odd-looking) aircraft, even though the garish livery is purely speculative, so that this model is, despite its roots in the real world and the attempt to stay true to the original, a fictional/whif piece. The finish is a bit rough, though, but that’s probably the price to pay when you create things from scratch.

Some background:

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

 

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

 

The technical requirements were:

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

• Capability to operate from grass strips and roads

• Maximum speed of Mach 0.95

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

• Armoured protection for the pilot and the fuel tanks

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

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

 

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

 

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

 

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

 

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

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

 

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

 

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

 

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

 

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

The kit and its assembly:

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

 

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

 

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

 

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

 

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

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

• The ejection seat and the dashboard, too

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

• From the landing gear only the main struts were taken

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

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

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

 

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

  

Painting and markings:

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

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

 

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

 

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

 

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

 

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

 

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

Some Background:

Antanas Gustaitis (March 26, 1898 – October 16, 1941) was an officer in the Lithuanian Armed Forces who modernized the Lithuanian Air Force, which at that time was part of the Lithuanian Army. He was the architect or aeronautical engineer who undertook the task to design and construct several military aircraft before WWII broke out.

 

Gustaitis was born in the village of Obelinė, in Javaravas county, in the Marijampolė district. He attended high school in Yaroslavl, and from there studied at the Institute of Engineering and School of Artillery in Petrograd. After joining the Lithuanian Army in 1919, he graduated from the School of Military Aviation as a Junior Lieutenant in 1920. Later that year, he saw action in the Polish-Lithuanian War. By 1922 he began to train pilots, and later became the head of the training squadron. He also oversaw the construction of aircraft for Lithuania in Italy and Czechoslovakia. Gustaitis was one of the founding members of the Aero Club of Lithuania, and later its Vice-President. He did much to promote aviation among the young people in Lithuania, especially concerning the sport of gliding. He also won the Lithuanian Chess Championship in 1922.

 

Between 1925 and 1928, Gustaitis studied aeronautical engineering in Paris. After his graduation he returned to Lithuania and was promoted to deputy Commander-in-Chief of Military Aviation and made chief of the Aviation Workshop (Karo Aviacijos Tiekimo Skyrius) in Kaunas. During this time, he reorganized the workshop and expanded its capability to repair aircraft as well. The aircraft he designed were named ANBO, an acronym for "Antanas Nori Būti Ore", which literally means “Antanas wants to be in the air” in Lithuanian.

 

Between 1925 and 1939, the ANBO design bureau developed, built and flew several trainers, reconnaissance and even fighter aircraft for the Lithuanian air force. The last projects, the ANBO VIII, a light single-engine reconnaissance bomber, and the ANBO IX, a single-seat fighter, were the most ambitious.

The ANBO IX started in 1935 as a light low-wing design with spatted, fixed landing gear and an open cockpit, powered by a British Bristol Mercury 830 hp (619 kW) 9-cylinder radial engine – a very clean all-metal design, outwardly not unlike the contemporary Japanese Nakajima Ki-27 or the Dutch Fokker D.XXI, but a much more modern construction.

A first prototype had been completed in summer 1936 and it flew for the first time on 1st of August, with good flight characteristics, but Gustaitis was not satisfied with the aircraft anymore. More powerful and aerodynamically more efficient engines had become available, and a retractable landing gear would improve the performance of the ANBO IX even more, so that the aircraft was heavily modified during the rest of the year.

 

The large Mercury was replaced with a Pratt & Whitney R-1535 Twin Wasp Junior, a two-row 14-cylinder radial engine with 825 hp and a much smaller frontal area that allowed the ANBO IX’s cowling to be wrapped much tighter around the engine than the Mercury’s former Townend ring, leading to a very aerodynamic overall shape. The oil cooler, formerly mounted starboard flank in front of the cockpit, was moved into a mutual fairing with the carburetor intake under the fuselage behind the engine.

The wings had to be modified to accommodate a retractable main landing gear: to make space for suitable wells, the inner wing section in front of the main spar was deepened, resulting in a kinked leading edge of the wing. The landing gear retracted inwards and was initially completely covered. The tail remained fixed, though, even though the former simple tailskid was replaced with a pressurized rubber wheel for better handling on paved runways.

 

These measures alone improved the ANBO IX’s top speed by 25 mph (40 km/h), and to improve the pilot’s working conditions the originally open cockpit with just a windscreen and a small headrest fairing was covered with a fully closed clear canopy and an enlarged aerodynamic spinal fairing that ended at the fin’s base. This additional space was used to introduce another contemporary novel feature on board: a radio set.

Together with some other refinements on a second prototype (e. g. a smaller diameter of the front fuselage section, an even more streamlined cowling that now also covered two synchronized machine guns above the engine and a recontoured wing/fuselage intersection), which flew in September 1937, top speed rose by another 6 mph (10 km/h) from 460 km/h (285 mph) of the original aircraft to a competitive 510 km/h (317 mph) that put the ANBO IX on a par with many other contemporary European fighter aircraft.

 

In this form the ANBO IX was cleared for production in early 1938, even though the desired R-1535 Twin Wasp Junior was not cleared for export or license production. With the Manfréd Weiss WM K.14 engine from Hungary, a derivative of the French Gnôme-Rhône 14 K with 900 hp, a similar, even slightly more powerful replacement could be quickly found, even though the adaptation of the airframe to the different powerplant delayed production by four months. Beyond a new engine mount, the machine guns in the fuselage and its synchronization gearbox had to be deleted, but the weapons could be moved into the outer wings, so that a total of four machine guns as main armament was retained. Additionally, a single ventral hardpoint was added that could either carry a single bomb with its respective shackles or – more frequently – a drop tank that extended the fighter’s rather limited range.

 

The Lithuanian air force ordered fifty of these machines, primarily to replace its Fiat CR.20 biplane fighters, and several regional export customers like Finland, Estonia and Bulgaria showed interest in the modern ANBO IX, too. Due to the complex all-metal airframe and limited workshop capacities, however, production started only slowly.

The first batch of six ANBO IXs arrived at Lithuanian frontline units in November 1939, more were in the ANBO workshops in Kaunas at that time in various stages of assembly. In 1940, the Lithuanian Air Force consisted of eight Air Squadrons, including reconnaissance, fighter, bomber and training units. However, only the 5th fighter squadron had by the time enough ANBO IXs and trained pilots to be fully operational with the new type. Air Force bases had been established in the cities and towns of Kaunas/Žagariškės, Šiauliai /Zokniai (Zokniai airfield), Panevėžys /Pajuostis. In the summertime, airports in the cities of Palanga and Rukla were also used. A total of 117 aircraft and 230 pilots and observers were listed in the books at that time, but less than ten of them were modern ANBO IX fighters, and probably only half of them were actually operational.

 

Following the Soviet occupation of Lithuania, however, the Lithuanian Air Force was formally disbanded on October 23, 1940. Part of Lithuanian Air Force (77 senior officers, 72 junior officers, 59 privates, 20 aircraft) was reorganized into Red Army's 29th Territorial Rifle Corps Aviation, also referred to as National Squadron (Tautinė eskadrilė). Other planes and equipment were taken over by Red Army's Air Force Bases No. 13 and 213. About third of Tautinė eskadrilė's personnel latter suffered repressions by Soviet authorities, significant share joined June uprising, after the start of German invasion into Soviet Union several pilots of Tautinė eskadrilė and fewer than six planes withdrew with the Soviet army.

The kit and its assembly:

This small aircraft model is the result of a spontaneous kitbashing flash, when I dug through the sprue piles and the spares box. It started with a leftover fuselage from a Mistercraft PZL P-7 fighter, and further searches revealed the wings from a PM Model Fokker D.XXI and the sawn-off wings from a Hobby Boss MS.406. The sprue stash came up with other useful parts like small stabilizers and a landing gear – and it turned out to be the rest of the MS.406, which had originally been butchered to be mated with the P-7 wings to become my fictional Polish RWD-24 fighter prototype. So, as a serious recycling project, I decided to accept the challenge and use the remains of the P-7 and the MS.406 to create a “counterpart” to the RWD-24, and it became the fictional ANBO IX.

 

While the ingredients for a basic airframe were now available, some parts were still missing. Most important: an engine. One option was an early Merlin, left over from a Spitfire, but due to the circular P-7 fuselage I preferred a radial engine. With the cowling from a Japanese Mitsubishi Ha-102 two-row radial (from an Airfix Ki-46 “Dinah”) I found a suitable and very streamlined donor, which received a small three-blade propeller with a scratched spinner on a metal axis inside.

 

The cockpit and the canopy caused more headaches, because the P-7 has an open cockpit with a rather wide opening. For a fighter with a retractable landing gear this would hardly work anymore and finding a solution as well as a suitable donor piece took a while. I initially wanted to use a kind of bubble canopy (with struts, so that it would not look too modern), but eventually rejected this because the proportions would have looked odd – and the overall style would have been too modern.

So I switched to an early Spitfire canopy, which had a good size for the small aircraft, even though it called for a spinal fairing – the latter became the half from a drop tank (IIRC from an Airfix P-61?).

 

Lots of PSR was necessary everywhere to blend the disparate parts together. The cockpit opening had to be partly filled and reshaped, blending both canopy and spine into the hull took several layers.

The area in front of the cockpit (originally holding the P-7’s shoulder-mounted wings) had to be re-sculpted and blended into the Ki-46 cowling.

The ventral area between the wings had also to be fully sculpted with putty, and huge gaps along the wing roots on the wings’ upper surfaces had to be filled and formed, too. No wonder that many surface details disappeared along the way… Nevertheless, the effort was worthwhile, because the resulting airframe, esp. the sleek fuselage, looks very aerodynamic, almost like a Thirties air speed record contender?

  

Painting and markings:

This is where the real trouble came to play. It took a while to find a suitable/authentic paint scheme for a pre-WWII Lithuanian aircraft, and I took inspiration from mid-Thirties Letov S.20 biplane fighters and the real ANBO VIII light bomber prototype. Apparently, a two-tone camouflage in two shades of green were an option, even though the tones appear debatable. The only real-life reference was a b/w picture of an S.20, and it showed a good contrast between the greens, so that my first choice were Humbrol 120 (FS 34227) and 172 (Satin Dark Green). However: 120 turned out to be much too pale, and the 172 had a somewhat grainy consistency. Leaving a horrible finish on the already less-than-perfect PSR mess of the model.

 

With a heavy heart I eventually decided to remove the initial coat of enamel paint with a two-day bath in foamed oven cleaner, which did the job but also worked on the putty. Disaster struck when one wing came loose while cleaning the model, and the canopy came off, too…

Repairs were possible, but did not improve the model’s surface finish – but I eventually pulled a second coat of paint through, this time with slightly different green tones: a mix of Humbrol 80 (Grass Green) and Revell 360 (fern Green), resulting in a rich but rather yellow-ish tone, and Humbrol 245 (RLM 75, Graugrün), as a subdued contrast. The result, though, reminded a lot of Finnish WWII aircraft, so that I gave the aircraft an NMF cowling (again inspired by the ANBO VIII prototype) and a very light grey (Modelmaster 2077, RLM 63) underside with a low waterline. This gave the model a somewhat Italian touch?

 

The national markings came from two different Blue Rider decal sheets for modern Lithuanian aircraft, the tactical code and the knight helmet as squadron emblem came from a French Dewoitine D.520 (PrintScale sheet).

 

After a black ink washing the kit received light panel post-shading to virtually restore some of the missing surface details, some weathering with Tamiya Smoke and silver was done and the model received a final overall coat of matt acrylic varnish.

  

Well, I am not happy with the outcome – mostly because of the painting mishaps and the resulting collateral damage overall. However, the kitbashed aircraft looks pretty conclusive and plays the role of one of the many European pre-WWII monoplane fighters with modern features like a retractable landing gear and a closed canopy well, it’s a very subtle result.

Some background:

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

 

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

 

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

 

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

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

 

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

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

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

The kit and its assembly:

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

 

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

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

 

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

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

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

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

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

  

Painting and markings:

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

 

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

 

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

 

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

 

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

  

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

I glued the front facade pieces together.

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

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.
