 but with two R27-300 engines. Supersonic performances would have implied many difficulties of development, and it was decided to initially develop a relatively simple aircraft limited to Mach 0.95. Although the Yak-38 and Yak-38M were developed from the land-based Yakovlev Yak-36, the aircraft had almost nothing in common.

The prototype VM-01 was finished on 14 April 1970. Though outwardly similar to the British Hawker Siddeley Harrier, it followed a completely different configuration. Together with a vectorable thrust engine in the rear used during flight, two smaller, and less powerful, engines were housed in the front portion of the fuselage and used purely for take-off and landing.The Harrier has only one engine, the thrust being vectored through nozzles fore and aft. The aircraft used a similar layout to the German experimental VTOL strike fighter, the VFW VAK 191B

 link with a computer system in the aircraft carrier which would allow it to be guided onto the deck with no interaction from the pilot.

Another advanced feature that Yak-38 possessed was an automatic ejection seat. When one of the take-off engines failed, once the aircraft rolled past 60 degrees the pilot was automatically ejected from the aircraft. The take-off engines did suffer some reliability problems while in service and this system saved the lives of a few Russian naval aviators.

Markings

The initial colour scheme worn by the AV-MF Yak-38 consisted of dark green anti-corrosion paint on the undersides of the aircraft, with dark blue upper surfaces. This was later replaced by a light grey over dark grey scheme, frequently associated with the Yak-38M. An unusual green-over-silver "tiger" camouflage scheme, reportedly seen on an aircraft onboard Leningrad in 1986, was probably applied for one cruise only. Special camouflage schemes may also have been applied to aircraft involved in the Romb-1 trials in Afghanistan in 1980.

Operational history

The majority of Yak-36M initial production deliveries were to the 279 OKShAP (Otdelnyi Korabelnyi Shturmovoi Aviatsionnyi Polk, Independent Shipboard Attack Air Regiment), initially based at Saki, the AV-MF’s training centre in Crimea

s) for training. The first AV-MF squadron embarked on Kiev in July 1976. On the conclusion of acceptance trials for the initial Yak-36Ms in August 1976 (Kiev was underway in the Atlantic at this point), the aircraft was formally accepted by the AV-MF in October, under the new designation Yak-38.

On its arrival in Murmansk, the 279 OKShAP was transferred to the Northern Fleet, with subsequent flying operations mainly being conducted from Severomorsk-3. The 299 IIAP (Issledovatlesko-Instruktorskiy Aviatsionnyi Polk, Research and Instructor Air Regiment) had been formed as a training unit at Saki in September 1976 to replace the previous unit within the Black Sea Fleet.

 operations. The passage of Minsk out of the Black Sea in February 1979 was duly followed by a major exercise involving two Kievs in the Mediterranean. On this occasion, five aircraft from each vessel conducted formation exercises in proximity to NATO observers.

The Yak-38’s limited useful payload was always its Achilles’ heel, but the high ambient temperatures that had been encountered in the Black Sea during the summer 1976 trials frequently prevented the aircraft from carrying any external stores at all, despite a reduced fuel load. Similar problems were then encountered when Minsk sailed off the coast of West Africa

During its first few years of ship-borne operations, the Yak-38 was not cleared to make rolling take-offs and run-on landings, leading some Western observers to believe the fundamentals of its propulsion design restricted the type to VTOL operations. In fact, shipboard short take-off trials had begun by December 1979, while experiments with run-on landings followed aboard Minsk between September 1980 and February 1981. V/STOL

 operations were made easier by the addition of a refined automatic flight control system, linked to a thumb switch on the pilot’s stick. Rolling take-offs were conducted with the lift engines deflected aft, the main engine nozzles being rotated automatically from 60° to 25° during the take-off run, before being slowly returned to the horizontal as the lift engines were shut down.

The Kievs normally embarked 12 single-seat Yak-38s, supplemented by two or three two-seat Yak-38Us, as part of an independent aviation regiment that also included two squadrons of (mainly anti-submarine warfare) helicopters. Of the seven landing pads available on the deck of each Kiev, all but one could accommodate the Yak-38.

 as part of a 50-day trial codenamed Romb-1, although the ‘hot and high’ conditions prevented any meaningful combat missions from being undertaken – in total, 12 combat sorties were made, but only two 100 kg (220.5 lb) bombs could be carried. In the event, any involvement would have been further limited by the ‘near-operational’ nature of the Romb-1 deployment (which also involved the first and third prototype Su-25s). The aircraft involved were not intended to be subject to combat, but rather tested under conditions that simulated the battlefield to a high degree. Despite their official non-operational nature, aircraft involved in the Romb trials could be requested to undertake combat sorties by local divisional commanders, on an ad hoc basis. The Yak-38s and prototype Su-25s operated out of a specially prepared air base near Shindand. Even with a much-reduced fuel and weapons load, the Yak-38 proved incapable of operating during the hot daylight hours (after around 0500 hrs). One aircraft was lost in Afghanistan due to non-combat causes.

In September 1982, - the third Kiev-class carrier - was commissioned. By now the V/STOL technique had been well practised, and the resulting increase in the Yak-38’s overall performance and capability was exploited during the passage of Novorossiysk from Severomorsk to join the Pacific Fleet. In a maritime context, the Yak-38 was not limited to the decks of Kievs. In September 1983, AV-MF pilots operated from the civilian Ro-Ro vessel Agostinio Neto, and NII-VVS pilots conducted further tests from another ‘Ro-Ro’, Nikolai Cherkasov. In both cases, use was made of a heat-resistant landing platform; further land-based trials tested the practicality of dispersed landing platforms, in a similar concept to the RAF’s Harrier operations in West Germany

.

However, towards the middle of the 1980s, the Yak-38 was removed from front line service and transferred to land-based operations. The aircraft proved to have problems in conditions of high heat/high humidity, was underpowered and lacked an adequate combat radius. In fact, due to these limitations, one of the nicknames that the aircraft earned in the Soviet naval jargon was "a pigeon of peace". Another less than flattering nickname earned due to inadequate combat radius was "fok-mast defense aircraft". In 1991, the type was retired from the Soviet Navy, and transferred to storage. A large number remain preserved as memorials.
