Some background:
In early 1968, the Soviet Ministry of Defense decided to develop a specialized shturmovik armored assault aircraft in order to provide close air support for the Soviet Ground Forces. The idea of creating a ground-support aircraft came about after analyzing the experience of shturmovaya (ground attack) aviation during World War II, and in local wars during the 1950s and 1960s. The Soviet fighter-bombers in service or under development at this time (Su-7, Su-17, MiG-21 and MiG-23) did not meet the requirements for close air support of the army. They lacked essential armor plating to protect the pilot and vital equipment from ground fire and missile hits, and their high flight speeds made it difficult for the pilot to maintain visual contact with a target. Ordnance load and loiter time were also insufficient.

In March 1969, a competition was announced by the Soviet Air Force that called for designs for a new battlefield close-support aircraft. Participants in the competition were the Design Bureaus of Sukhoi, Yakovlev, Ilyushin and Mikoyan. The original request was for a simple, relavtively light aircraft, that was easy to produce and maintain and would allow a high survivabilty in a combat environment.

The aircraft was to be powered by two Ivchenko AI-25T non-afterburning turbofans, each with a thrust of 1.750 kgp (3.860 lbst) - a modification of the AI-25 developed for the Yak-40 feederliner, and the same engine that powered the Czech-built L-39 Albatros trainer. The aircraft was to carry an internal cannon and was only intended to carry unguided weapons - bombs of up to 500 kg caliber and rockets/rocket pods.Sighting was to be simple, consisting of a collimating gunsight and a laser rangefinder.
Normal combat payload was to be 1.500 kg (3.310 lb), increasing to 2.500 kg (5.511 lb) in overload configuration. Normal TOW would be 8.200 kg (18.080 lb) and MTOW in the 10.000 kg (22.050 lb) range.

All OKBs made submissions, but in the course of the proposals the requirements were widened, eventually necessitating a bigger, more capable aircraft. This eventually led to the Ilyushin's Il-42 (later renamed into Il-102) and Sukhoi's T-8 (the later Su-25), which remained in the official competition and the Su-25 would, aftre a long development phase, turn out to be the winner.

OKB Yakovlev had been late with its submission, which was still based on the original requirement. it was clear that their aircraft, internally known as the Yak-35, would neither meet the more demanding profile, nor offer the development potential for a heavier type. Anyway, OKB Yakovlev kept the development going, as a lot of export potential was expected.

Until May 1970 a total of three prototypes were built and successfully tested. The Yak-35 was a compact aircraft with clean lines, and it took the experience from the recently built (but rejected) Yak-30/32 trainer (NATO code "Magnum/Mantis") further. The modern design featured shoulder-mounted, slightly swept wings and a swept cruciform tail. The AI-25T engines were buried side by side in the rear fuselage, fed by lateral air intakes. The pilot sat in an armored cockpit that would withstand 0.5" caliber fire, and the slanted nose offered good for- and downward view. The aircraft reminded vaguely of the Saab 105 trainer or Sukhoi's initial, light T-8 design.

The rugged landing gear with single low pressure tires retracted into the fuselage. Armement compriseda pair of 30mm Nudelman-Richter NR-30 cannons with 100RPG, mounted under the air intakes, and a total of seven hardpoints (three under each wing, one under the fuselage) for ordnance. The inner pair of pylons was "wet" and could carry PTB-600 drop tanks, the fuselage hardpoint was intended for extre equipment like a reconnaissance pod, an ECM jammer or (in later versions, see below) guidance pods for air to ground missiles. For self-defence, IR-guided missiles like the R-3S, R-13M and later the R-60 could be carried on the outer pylons.

Avionics included a passive SPO-10 Sirena 3M RHAWS, coupled with a set of KDS-23 chaff/flare dispensers at the rear base of the fin, and an active SPS-141 Siren jammer. A Fon laser rangefinder was fitted into the nose tip, coupled with an S-17VG-1sighting mechanism, a DISS-7 doppler speed and drift measurement unit and a PKB-3 sight for toss bombing, an ASP-17B gunsight, an RV-5R radar altimeter and a V-144 computer.

Western officials first became aware of the new type during the October Parade 1972 in Moscow, when the three initial Yak-35 made a single pass at medium altitude. The unknown type immediately received the NATO code "Fraudster". The prototypes and two static airframes continued the development program at slow pace - no serious problem occured, and the Yak-35 turned out to be a stable and agile weapon platform, receiving positive praise from the test pilots.

As time went by, things turned into favor of the the Yak-35, which eventually got its chance: As the shturmovaya program around the Su-25 ran into more and more delay, and a new attack aircraft was direly needed - not long ago, tensions with China concerning the disputed Damanskiy and Kirkinskiy Islands on the Ussuri River had caused much alert. Finally, the Yak-35 was ordered into production, while parts of its fuselage design had already been used for the Yak-38 VTOL aircraft for the Soviet Navy.

From 1974 on the Yak-35 was delivered to front line squadrons, in parallel with the VG Su-17 fighter bomber. The service aircraft were updated with Delta-N radio guidance equipment, placed in a fairing in front of the fin, which would allow the Yak-35D ('dorabotanyy' = Updated; NATO code "Fraudster B") to carry radio-guided AGMs like the Kh23 or Kh-25 missiles. The emitter had to be carried in an external pod, though, normally placed under the fuselage. A pair of these missiles could be carried on launch rails on the inner pair of pylons.

A total of 110 Yak-35Ds were built until 1979, all of them remained in Soviet Air Force Service, and almost exclusively in transbaikalian units. None of them were deployed to Afghanistan, as the rather weak engine powered was deemed unsatisfactory for the 'hot and high' conflict theatre.
From 1982 on the Yak-35Ds were quickly replaced by the then-finally-ready Su-25 and relegated into second line services. Most of the remaining Yak-35Ds were kept in use for weapon training, mostly at flight academies along MiG-21 fighters until 1990, and some served as target tugs with frontline units in the Far East. No specimen was ever exported.

The kit and its assembly:
This fantasy thing was spawned by the vague thought that one could turn the rather crude Yak-38 kit from Tsukuda Hobby into "something pretty". The plan had been lingering for some time, and when I got hands on an incomplete Yak-38 (Revell re-boxing of the kit, canopy missing) I eventually started with the surgery, letting inspiration and donation parts flow.

I had a vague idea of what the aircraft should look like, but the overall layout evolved step by step. One initial measure was to shorten the fuselage considerably: plugs from in front of and behind the original wings were cut out, and the remaining three fuselage pieces glued together. As the fuselage has an almost even diameter and shape all along its length, this turned out to be pretty easy, but still needed considerably putty work.

The original fittings for the wings and tail surfaces were then filled with styrene plugs and sanded even.

Moving the wings from their original mid-position to the shoulders was already something I had in mind before the project started. But the eventual solution just evolved as I had the fuselage ready and could judge positions and proportions.

The wings I used come from a Alpha Jet (Heller), and they were not simply stuck to the fuselage. Due to the curved back of the Yak-38 I had to add a kind of console, made from the upper wing's mid section of a Matchbox SBC Helldiver biplane (!). This connector piece was placed into a carved fairing on top of the fuselage, the new wings attached to it, and the missing bodywork sculpted with 2C putty. This way I was able to blend the new arrangement into the rest of the body with matching wing roots, without having it look as if the wings had simple been stuck onto it. The result is pretty good, looks rather organic.

The tail is new, too. Original plan had been to use the Yak-38 tail, maybe with a T-tail arrangement - but that simply did not look good. Finding a replacement was tough, I finally settled on an A-4M (Italeri) fin, which had to be modified with a clipped top, Yak-38 style, in order NOT to remind too much of the Douglas creation! It fits in shape and size, though.

New stabilizers had to be used, too - the original Yak-38 looked much too small and flimsy. A T-tail was not possible anymore, so I used a cruciform tail, A-4 style, even though the stabilizers had to be moved upwards since the Yak-38 tail is much wider than an A-4. The stabilizers themselves are new, too: a pair of F-86 fins(!), leftover from Hobby Boss kits. They are a bit thick, but look great and blend well into the whole arrangement.

The main landing gear was taken OOB, but with new wheels and extra struts fitted. The front wheel is totally new, it belongs to a Fiat G-91. The cockpit received a new seat (from a MiG-29), a pilot figure and a primitive dashboard, and a donation canopy had to be found and integrated (I think it comes from a Tamiya 1:100 F-105).
All around the hull small details were added, including the seven pylons and the rocket pod ordnance.

Painting and markings:
It took a while and some research to turn up a suitable, tactical paint scheme. Normally I keep whifs rather subtle, and I did not want to paint the Yak-35 in a dark green/brown scheme, typical for Eastern Europe aircraft.
Afghanistan was a vague idea, a desert/mountainous scheme, as well as the Su-25 prototype which appreared at Le Bourget ("301 Blue"), with its two-tone brown livery and a few green accents.

I finally found a Su-7UM trainer in a light, three-tone camouflage which I transplanted on my Yak-35. It consists of two sand tones (Humbrol 187 and 63) and a green tone (Humbrol 155). Looks rather surreal! The undersides are kept in Russian Blue (Humbrol 115).

Since much of the fuselage consists of pure putty and re-engraving would be rather hazardous I painted panel lines, with a mix of sepia ink and acrylic matt varnish. A second-best solution, but the result is O.K., when you do not take a closer look...

The whole thing received a light wash with black ink in order to emphasize panel line and details and the leading edges were lightly dry-brushed with pale grey. Basic colors were also 'tamed down' trough dry painting with shades of light beige and grey, for a worn and bleached look.

Cockpit interior was painted in typical, Soviet "anti fatigue" turquoise, the landing gear was painted in a mix of Aluminum and Olive Drab. Di-electric panels were painted in a bright green, a mix of Humbrol 2 and 175.

Most markings come from the scrap box, insignia and tactical code come from a Carpena Decals 1:72 MiG17 aftermarket sheet.

This thing was a major surgical act, but turned out nicely. With an arrestor hook this could also have become a maritime fighter bomber, e. g. an alternative to the French Dassault Ètendard or the Jaguar M? It looks familiar, has some serious Su-25 appeal, yet the thing looks unique. And the desert/mountain style paint scheme suits the aircraft well.

Finally, a look behind the scenes - typical poster backgorund arrangement with a self-made model kit holder  ;D

This looks great, from the finished pictures you'd never guess how much of the kit has been replaced (or consists of putty).

Hey, I like both your model and the backstory Dizzyfuga - especially where and how you tied the replacement of the Yak-35 with the real-world Su-25👍
Also like your NATO code "Fraudster"👍
