The Mikoyan MiG-31 Foxhound is a supersonic interceptor fighter designed in 1975 to replace the Mikoyan MiG-25 Foxbat.



MiG-31 of the Russian Air Force

Despite being labeled as an 'improved Foxbat' in reality the MiG-31 is a completely new aircraft, with greater capability than the MiG-25; although its maximum speed is reduced to keep from red lining and potentially damaging its engines. The development of the MiG-31 began in the mid-1970s and by September 16, 1975 the first prototype flew.It was initially designed to intercept the Mach 3 capable XB-70 Valkyrie and other strategic bombers before the can deliver their payload.

The West first became aware of the MiG-31 when Viktor Belenko mentioned a 'Super Foxbat' while being debriefed following his defection in 1976.
