THE RUSSIAN RECONNAISSANCE MAESTRO AND THE COLD WAR HERO
The Mikoyan-Gurevich MiG-25 (NATO reporting name: Foxbat) is a supersonic interceptor and reconnaissance aircraft that was one of the first to enter service. It was designed by the Soviet Union's Mikoyan-Gurevich studio and is one of the few combat aircraft made entirely of stainless steel. It was to be Mikhail Gurevich's final plane before his retirement.

During the Cold War, the Soviet Air Defence Forces, PVO (not to be confused with the Soviet Air Force, VVS), were tasked with strategic air defence of the USSR. This included not just dealing with unintentional border transgressions, but also guarding the USSR's enormous airspace against US observation planes and strategic bombers carrying free-fall nuclear bombs. The performance of these planes has continually improved. The Lockheed U-2's very high altitude overflights of Soviet territory in the late 1950s demonstrated the necessity for a higher altitude interceptor aircraft than was available at the time.
The Mach 2 Convair B-58 Hustler succeeded the subsonic Boeing B-47 Stratojet and Boeing B-52 Stratofortress strategic bombers, while the Mach 3 North American B-70 Valkyrie was on its way at the time. The PVO defence system needed to be upgraded significantly, and at the beginning of 1958, a request was made for manned interceptors capable of reaching 3,000 km/h (1,600 kn) at heights of up to 27 km (89,000 ft). Both Mikoyan and Sukhoi responded.
