The Mikoyan MiG-31 "Foxhound" was born as an all-weather, all-altitude offshoot of the earlier MiG-25 "Foxbat" supersonic interceptor of the Soviet Union. It was developed specifically to succeed the aging Tu-28/-128 "Fiddler" in its supersonic interceptor role. Unlike the MiG-25, the MiG-31 introduced a second crewman and, with its powerful radar and missile armament, can engage multiple targets at extreme ranges with deadly efficiency. Despite its Cold War roots, the MiG-31 enjoys an extended service life with the Russian Air Force mainly due to extensive modernization of its various systems and weapons. 519 total aircraft were produced from 1975 to 1994 though only three global operators ever fielded the type - Russia, Kazakhstan, and the former Soviet Union.
