After testing the first VTOL Yak-36 and because of its construction in hopelessness AS series. Yakovlev, drawing on the experience of the British, He insisted on the creation of a new aircraft with one lifting and sustainer engine. At the same time, a group of designers OKB headed by SG. Mordovin led its development VTOL, but with a combined power plant. AS. Yakovlev, I learned about it, forbade experts EDO participate in this work. At the beginning of summer 1967 g. This group commenced prior to designing VTOL propulsion system of two lifting and hoisting one main engine. As a result, the general form have been developed, layout and the basic ideology of the aircraft.

The dispute was resolved in the scientific and technical council in favor of the MAP project Mordovina, EDO and ordered to prepare a draft. The beginning of works - from the decision of the government of the USSR number 1166-413 from 27 December 1967 g.
for schematic design work began in September 1968 g. In April of the following year he was shown the layout of the aircraft, and the first instance of a pilot of the Yak-36M number 1. The plane is the average plan normal aerodynamic scheme with a combined power plant, consisting of two lifting (AP) and a lifting and sustainer (PMD). vertical and transient conditions is controlled by means reactive control systems, air which is taken from the compressor. PD are arranged behind the cockpit are used only in the vertical and transitional flight regimes. Nozzle Front deployed PD 15 ° back, and the rear nozzle - 15 ° forward. PMD nozzle is equipped with two rotating nozzles. For vertical takeoff relining rotary nozzles is made with detent steps 25 ° and 45 ° from the vertical.
pilot rescue system on the Yak-38 plane has its own characteristics. It includes automatic ejection. The system is switched off, PMD if the angle exceeds 67 ° nozzles (from vertical). In normal flight catapult necessary for operation, to PD wing has been closed, Only in this case, the lamp will be reset. In other cases, the bailout occurs through the skylight glazing.
15 May 1970 g. the first copy was delivered to the LII, which was tested for "cable crane", airplane hung at a height of 0 to 5 m and starts the motor. First free hovering on the aircraft performed a test pilot VG. Mukhin 22 September 1970 g. The first flight in self-flight was made 2 December 1970 g. The first flight of "full profile" was made as a test pilot MS. Deksbahom 25 February 1972 g. For the sea trials was isolated anti-cruiser (PKR) "Moscow". First landing on it made MS. Deksbah 18 November 1972 g. This day is considered the birthday of carrier-based aircraft.
AT 1973 g. it was decided to start Yak-36M into mass production at the Saratov factory (released 231 a car). In August 1977 g. Yak-36M was adopted by the Navy aircraft under the designation Yak-38. for 15 years of operation occurred 36 flight accidents, of them all 8 accidents. Over time, interest in VTOL down, and 1991 g. they have displayed in reserve.
