MiG-31 Mikoyan Gurevich
MiG-31
ASCC codename: Foxhound
Interceptor

DESCRIPTION:
The MiG-31 was developed during the 1970s as an improved version of the MiG-25 supersonic fighter. The two-seat MiG-31 was foreseen as a high-speed interceptor to counter the threat of low-flying supersonic aircraft and cruise missiles. Though outwardly very similar to the MiG-25, the MiG-31 is largely a new design. The airframe has been strengthened for supersonic flight at low altitudes, new engines have been adopted, and a much more powerful tracking radar is installed.

The MiG-31 'Foxhound-A' started entering service in 1983 and soon began replacing older MiG-25 models. Production later switched to the improved MiG-31B series with various avionics updates. Numerous advanced models were also proposed including the MiG-31M with significantly enhanced avionics and weapons. Though the MiG-31M represented a major improvement over earlier production aircraft, only a handful were built and the aircraft never entered service.

Approximately 500 total MiG-31 aircraft were built for the Soviet Union and Russia. Approximately 40 ended up in Kazakhstan after it gained independence and about 30 were operational as of 2011. Dedicated MiG-31E and MiG-31FE export models were also developed but none was successfully sold to foreign users.

Reports first emerged in 2007 that Syria was negotiating to buy the MiG-31, and these rumors appeared again in 2009. Although no deal has been concluded so far, some observers suspect the purchase is actually being made on behalf of Iran using Syria to bypass international sanctions.
