Russia’s Defense Ministry Discussing Development of VTOL Plane for Aircraft Carrier | Navy Recognition - 20 July 2017
Quote
The Yakovlev Design Bureau started developing the Yakovlev Yak-141 (Freestyle) multirole supersonic VTOL fighter jet in the mid-1970s.

The plane performed its first flight in 1987. The Yak-141 aircraft were planned to make part of the air wing of the heavy aircraft carriers, the Novorossiysk, Baku (the future ship Admiral Gorshkov), Tbilisi (currently known as the Admiral Kuznetsov), Riga (the future ship Varyag) and Ulyanovsk.

The Yak-141 plane landed on an aircraft carrier for the first time in 1991. The production of the aircraft was ceased in 2003.

FYi...

The F35'S vertical takeoff and landing (VTOL) fundamental design is nearly three decades old. It is based on the Yak-141 design.

Down to the tail.nozzle that would tilt downwards, to the single engine design, to the twin tail, etc. The obvious similarities in configuration are all there. Except of course the stealth requirement of the JSF competition made neccesary a substantial redesign in the airframe, use of composite material, the gazillion lines of codes, etc.

What Lockheed gained is the knowledge of how the Yak-141's VTOL/STOL system worked. Then they basically improved upon a design which the Soviets couldn't make succesful, reworked what needed reworking, added what the JSF competition requirements made neccesary, and viola!
