The Mikoyan MiG-31 Foxhound is a large, twin-engine supersonic aircraft designed to intercept foreign planes at high speeds. The two-person plane made its first flight in September 1975, and was introduced into service in the Soviet Air Defense Forces in 1982.

The MiG-31 reached published speeds of Mach 2.83 (1,860 mph, or 3,000 km/h), and was capable of flying supersonic even at low altitudes. The MiG-31 is still in service in the Russian Air Force and Kazakhstan Air Force.
