The West firstly learned of the MiG-31 from a Soviet MiG-25 pilot named Lieutenant Viktor Belenko who defected to Japan in 1976. He testified that the Soviet Union was developing a new interceptor which he called it as Super Foxbat.
The MiG-31 Foxhound was mainly based on the design of its predecessor, the MiG-25 Foxbat, an interceptor and reconnaissance aircraft which has a top speed of Mach 2.83+. The MiG-25 Foxbat itself had sparked off fear in the West, prompting significant development of the F-15 Eagle. However, the Soviet Union thought that a better long-range interceptor should be developed.
Then the Ye-155MP was developed, the first prototype which later would be the MiG-31 Foxhound which had its first flight in September 16, 1975. The Ye-155MP was the improved version of the MiG-25 Foxbat. As a result of reducing structural mass by doubling the use of titanium up to 16% and using more aluminium content up to 33%, the Ye-155MP could perform supersonic flight at low altitude. The prototype also could increase its fuel capacity and had more efficient low bypass ratio turbofan engines.
The Ye-155 than re-engined and turned into the Ye-266 which achieved maximum altitude of 37,650 m or 123.524 ft reached a record of having 4,000 m of height in just 4 minutes 11.78 seconds.
The development continued until the MiG-31 was massively produced. Since 1979 up to 2000, reportedly there were 400 units of MiG-31.
Operational history of the MiG-31 Foxhound
The Soviet Anti-Air Defense firstly operated the MiG-31 in 1982. Unfortunately, following the collapse of the USSR in 1991, budget became a big problem. Then maintenance of the MiG-31 collapsed, many squadrons could not afford the cost.
There was only 20% of remaining aircraft able to serve the country. Fortunately, in early 2006, following a recovery of Russian economy, the country was able to allow around 75% of the MiG-31 Foxhound to get back in service. There are approximately active 370 units of the MiG-31 in Russia.
MiG-31 usage for tourism flight
Civilians also have opportunities to fly the MiG-31 Foxhound. As this long-range interceptor has service ceiling of 20,600 m (67,600 ft), many aviation enthusiasts have enjoyed their time having the edge of space flight which can be done in Russia.
