Mikoyan MiG-31

The MiG-31, NATO name Foxhound, is a supersonic interceptor developed for the Soviet Air Forces by the Mikoyan bureau to replace the MiG-25, on which it is based. It is the fastest known operational combat aircraft, with a top speed near 3,000 km/h. Development began with the Ye-155MP prototype, which first flew on 16 September 1975, and serial production started in 1979, with about 500 aircraft built. Russia still operates it and expects to keep it flying until at least 2030, with airframe lives extended from 2,500 to 3,500 hours. The MiG-31K variant carries the Kh-47M2 Kinzhal air-launched ballistic missile. Kazakhstan, the other operator, retired its aircraft in 2023.
