Design

Since 1975, in front of deficiencies of the Yak-38 (subsonic Speed, rudimentary, weak avionics capacities of carrying and autonomy), the research departments of Yakovlev started the study of a remplaçant.
The Yak-141 is conceived like its predecessor with an engine with vectorial push for lift and cruising, plus two vertical engines used at the time of the phases stationnaires.
There were two prototypes built like two cells for the static tests. The Yak-141 accomplished its first flight with traditional takeoff on March 9th, 1989 then its first vertical takeoff on December 29th, 1989. The second prototype will be seriously damaged on October 5th, 1991 at the time of a landing on the aircraft carrier Admiral Gorchkov . The first was presented at the time of the aeronautical Salon of Farnborough in 1992, but it was not unknown Westerners, because it was located on the basis of test of Joukovsky by an American satellite of observation, in the middle of the years 1980. It is there that it accepted code NATO Freestyle .
After the fall of the Soviet Union, the Fédération of Russia suspended the program for lack of appropriations. The research department of Yakovlev however continued the development of improved versions.
