The Sukhoi Su-9 (ASCC reporting name: Fishpot) is a single-engine, all-weather, missile-armed interceptor aircraft developed by the Soviet Union.

(not to be confused with the other Su-9, idk why they decided to use the same name twice)

The Su-9 emerged from aerodynamic studies by TsAGI, the Soviet aerodynamic center, during the Korean War, which devised several optimum aerodynamic configurations for jet fighters. The design first flew in 1956 as the T-405 prototype. The Su-9 was developed at the same time as the Su-7 "Fitter", and the West first saw both at the Tushino Aviation Day on June 24, 1956, where the Su-9 was dubbed Fitter-B. It entered service in 1959.

On September 4, 1959 a modified Su-9 (designated T-431 by the bureau) piloted by Vladimir Sergeievitch Ilyushin set a new world record for absolute height, at 28,852 m (94,658 ft). In November of the same year, Ilyushin set several new sustained speed/altitude records in the same aircraft.

The Su-9 has been frequently mistaken for the MiG-21 due to the many similarities in design. The primary distinguishing features are the Su-9's size and its bubble canopy.
