The MiG-31 started life as an advanced derivative of the famous MiG-25P
interceptor, becoming the first Soviet fourth-generation combat
aircraft. First flown in 1975, it differed from its progenitor primarily
in having a crew of two (pilot and weapons systems operator), a highly
capable passive phased-array radar - a world first - and new R-33
long-range missiles as its primary armament. The maximum speed was an
impressive Mach 2.82, the cruising speed being Mach 2.35. The type
entered service in 1981; more than 500 copies were built between 1981
and 1994. The powerful radar and other avionics allowed the MiG-31 to
operate as a 'mini-AWACS' scanning the airspace and guiding other
interceptors to their targets; a flight of three such aircraft in line
abreast formation could cover a strip 800 km (500 miles) wide. To this
day the MiG-31 remains one of the key air defense assets of the Russian
Air Force.
The book describes the MiG-31's developmental history, including upgrade
programs, and features a full and comprehensive survey of the various
MiG-31 model-making kits currently available on the market.
