Although it was capable of reaching speeds exceeding Mach 3.2 (3,445 km/h (2,141 mph)) this would result in the engines accelerating out of control and needing replacement. Therefore, the operational top speed was limited to Mach 2.83 (2,743.2 km/h (1,704.5 mph)). The MiG-25 features a powerful radar and four air-to-air missiles, and it still holds the world record for altitude reached by airbreathing piloted aircraft of 38 km (125,000 ft).
Production of the MiG-25 series ended in 1984 after completion of 1,186 aircraft. A symbol of the Cold War, the MiG-25 flew with Soviet allies and former Soviet republics, remaining in limited service in several export customers. It is one of the highest-flying military aircraft...
