The first combat aircraft of Soviet design conceived specifically for shipboard operation to achieve series production, the Yak-38 single-seat carrier-borne air defence and strike fighter was evolved from the Yak-36M. Flown in prototype form in 1971, the Yak-36M was developed under the design leadership of S Mordovin for the primary tasks of fleet air defence against shadowing maritime surveillance aircraft, reconnaissance and anti-ship strike. Power plant combined a Yu Gusev-developed Tumansky R-27V thrust-vectoring turbojet with two Rybinsk (Koliesov) RD-36-35 vertical-lift turbojets designed by a team led by A Dynkin. Hydraulic drives synchronised by a transverse shaft rotated the thrust-vectoring nozzles aft of the wing, their output in vertical take-off and landing operations being balanced during hover and transition by the paired lift engines mounted in tandem immediately aft of the cockpit and inclined forward 13° from the vertical.
Shipboard trials with the Yak-36M began aboard the Moskva half-deck anti-submarine cruiser in 1972, and, in the following year, the decision was taken to build a pre-series of Yak-36M fighters for service evaluation, the first two of these landing aboard the carrier-cruiser Kiev in 1975. An evaluation squadron comprising 12 single-seat Yak-36Ms and two two-seat Yak-36Us embarked aboard the Kiev in the summer of 1976, the aircraft being confined to vertical take-off with conversion following at 5-6m above the deck. During 1976, production was initiated of a much improved version of the basic design as the Yak-38. Externally similar to the Yak-36M, apart from substantial strakes either side of the intake for the lift engines, the Yak-38 possessed a full weapons system and an automatic control system permitting a short roll leading into vertical take-off as distinct from an orthodox short take-off benefiting from wing-induced lift.
The Yak-38 entered service with the Soviet Navy in 1978, and, during 1980, was evaluated under operational conditions in Afghanistan. Progressive development resulted in the Yak-38M, which, with 1000kg more engine thrust, a steerable nosewheel and provision for paired 600-litre underwing auxiliary tanks, entered production in succession to the Yak-38. The Yak-38M had a 6940kg R-27V-300 thrust-vectoring turbojet and two vertical-lift RD-38 turbojets each rated at 3250kg. Two wing stations immediately inboard of vertically-folding panels provided for two gun pods each containing a twin-barrel 23mm GSh-23 cannon, rocket packs or bombs weighing up to 500kg each, two R-60 IR-homing AAMs or short-range ASMs. The tuitional version, the Yak-38UM, had vertically-staggered tandem seats, a plug being inserted in the aft fuselage to compensate for a lengthened nose. Each of the four Soviet Navy Kiev-class carrier cruisers received a 14-aircraft squadron of Yak-38s or -38Ms (each including two two-seaters), and production was completed by 1987 with a total of 231 Yak-38s (all versions) built.

The Yak-38 was intended to be the Soviet Union's answer to the Harrier, but it really wasn't. The Harrier took off, flew and landed, all with a single engine. The Yak-38 required three engines, two of which were shut down except during take-off and landing. The rest of the time the two extra engines were merely dead weight and wasted space, reducing the aircraft's capacity to carry fuel, electronics and weapons. As a result, the Yak-38 could do what the Harrier could do, but not as efficiently.

Looks like a hairrier without the jump engines.
Mr HTIAN the Yakovlev Yak-38's only spent a month in Afghanistan in an operation called Romb-1 and preformed poorly do to the Heat and altitude they were operating in. The number of Yak-38's was no more than 4 and they were regulated to early morning flying and that was it. There are no other known combat operations of the Yak-38 and they are no longer in service as of 1995. Were supposed to be replaced by Yak-141 but that failed to get financing. 30 years of studying Soviet Aircraft.

I would like to know its experimental fighting and history in modern war. And I want to know its weight
I am able to offer demilitarized Yak-38s for sale to civil buyers. Contact me for more information.
What happen to the example?
Do you have any comments about this aircraft ?
FACTS AND FIGURES
© The 'Forger' had a system to
automaticaliy eject the pilot if
the engine stopped while the
thrust was angled below the
horizontal. On one occasion this
occurred in full view of a British
carrier, who rescued the pilot.
© A hinged door opened behind
the cockpit to feed air to the lift
jets, which exhausted out of a
hatch at the bottom.
© The 'Forger' was very basically
equipped, with only a simple
weapons sight and no radar or
radar warning systems.
© Although intended only for
vertical take-offs and landings, the
'Forger' had double-slotted flaps
and a braking parachute.
