Mikoyan MiG-31 "(Foxhound)"

Supersonic Interceptor

Supersonic Workhorse.

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.

The Need for Speed

High speeds at high altitudes necessitate that the MiG-31 be specially constructed. As such, it features light alloys, nickel steel, and titanium in its airframe design.

I See You

The MiG-31's powerful onboard radar allows for automated tracking of up to 24 targets with simultaneous engagement of eight threats - the onboard computer further dictating the top four.

High Performance

The twin Soloviev afterburning turbofan engines provide maximum power at all altitudes, the aircraft capable of reaching Mach 2.83 up to a ceiling of 82,000 feet.

Legs for the Journey

With two installed external fuel tanks and carrying a full complement of R-33 air-to-air missiles, the MiG-31 can reach out to ranges of 1,900 miles. An air refueling quality gives it even greater legs in the sky, making it an ideal deterrence over the vastness of the Russian frontier.
