Su-9 Samolyet K

The Sukhoi Su-9 (Russian: Самолёт K, lit. 'Aircraft K'; USAF/DoD designation: Type 8) was an early jet fighter built in the Soviet Union shortly after World War II. The design began in 1944 and was intended to use Soviet-designed turbojet engines. The design was heavily influenced by captured German jet fighters and it was subsequently redesigned to use a Soviet copy of the German Jumo 004 turbojet. The Su-9 was slower than competing Soviet aircraft and it was cancelled as a result. A modified version with different engines and a revised wing became the Su-11 (Samolyot KL), but this did not enter production either. The Su-13 (Samolyot KT) was a proposal to re-engine the aircraft with Soviet copies of the Rolls-Royce Derwent turbojet as well as to modify it for night fighting, but neither proposal was accepted.
