Designed by P.O.Sukhoj and included the crash program in 1945. Given authorisation in May 1944 for two prototypes and one static-test airframe. The Sukhoi Su 9 was by far the best of the first generation of Soviet jets and as good if not better as any thing in the West at the time.
Thought of as a copy of the Me 262 because of it's lay out, the aircraft was of a completely indigenous design, the Su 9 had it's first flight in August 1946, flown by G.Kochyetkov. One prototype was demonstrated to the world at the Tushino airforce parade on the 3/7/1947. The NII considered the Su-9 so good it recommended series-production as soon as possible, but the Su-9 never went into production as it's resemblance to the German Me 262 made the authorities (Stalin) uncomfortable and would lead in the end to Sukhoj's design bureau being closed in November 1949 and Sukhoj "falling out of favour" until the death of Stalin.
|Improvements were made to the Su-9 in late 1946, resulting in the Su-11. Little changed to the Su-9 apart the fitting of two Lyulka TR-1 engines (the first aircraft to be fitted with Lyulka turbojet engines). The Su-11 had it's maiden flight on 28/5/1947, as with the Su-9 an outstanding aircraft, but a jealous A.S.Yakovlev told Stalin "Copy of the Me 262 and dangerous to fly".|
