Su-7, P.O.Sukhoj
|
Single-seat experimental fighter development of the Su-6 ground attack aircraft, used to test combined powerplant: piston engine and liquid rocket booster. Armor shell was deleted, size an shape of aircraft was not changed.
Rocket engine could be turned on and off as needed. Its total fire time was 4 minutes, providing faster takeoff and substantial speed increase, but without the booster performance was far from remarkable compared to that of fighters already in production.
Remained experimental.
Later designation Su-7 was used for Su-7B front line jet bomber.
