Interceptor developed from the Mig-25. Project under designation MiG-25MP initiated in 1972, and first flight (test-pilot A.Fedotov) took place on September 19, 1975. In mass production since 1979, more than 500 MiG-31 and MiG-31B built. Two-seat aircraft has a re-designed lighter airframe (see table). Missile armament was almost doubled with 4 catapult launchable missiles and powerful cannon added.

The first (and the only at the 1996) mass production interceptor in the world equipped with fixed Pulse-Doppler radar, allowing simultaneous tracking of 10 targets and firing against four of them. An unit of four MiG-31 can link their radars together, to establish a search pattern - covering a width of 800-900km with four aircraft, spaced at 200km. MiG-31 may also serve as an airborne command center to guide fighters with less powerful radar equipment (MiG-23, MiG-29, MiG-21-93).
Landing gear allows to use MiG-31 from unpaved airstrips (is there any other Mach 3 aircraft with such a capability?).
