The Yakovlev Yak-38 (Russian: -38, NATO reporting name: Forger) was Soviet Naval Aviation''s first and only operational VTOL multi-role combat aircraft.The first drawings showed a supersonic aircraft strongly influenced by Hawker P.1154 in study in the United Kingdom 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.
