Myasishchev M-55
From Wikipedia, the free encyclopedia
The Myasishchev M-55 (NATO reporting name: Mystic) is a high altitude reconnaissance aircraft developed by the Soviet Union's Myasishchev design bureau. It is similar in both its mission and design to the American Lockheed U-2 spy plane. It is a development of the M-17. Differences include two turbofan engines instead of one and greater MTOW.

[edit] Overview
The M-55 was first known as the M-17. Its life began in 1978 when Soviet engineers searched for ways to intercept American unmanned reconnaissance balloons. The first flight of the M-17 was 26 May 1982; this aircraft was soon detected by U.S. observers. With the introduction of another model of this class, this interceptor M-17 would later become known as the M-17 Mystic-A.
The Mystic-A set 25 world records for its class. However, this balloon-interceptor model was terminated in 1987 and replaced by the M-17RN, also known as the M-55 Geophysica, which was dubbed by NATO Mystic-B. The first one of these flew in 1988, but as the Soviet Union collapsed, military demand dropped. In 1994, the reconnaissance version was terminated after only five aircraft built.
A number M-55 Geophysica remain in service, performing in research roles. One M-55 took part in a study of the Arctic stratosphere in 1996-1997.
