The Myasishchev M-50 (NATO: Bounder) was a Soviet prototype four-jet engine supersonic strategic bomber. Only one prototype was built and it participated in the Soviet Aviation Day fly-by in 1961. As with many of the early 1960s supersonic strategic bomber projects, the M-50 never entered service as the program was terminated due to the development of Intercontinental ballistic missiles and the priority assigned to the Soviet space program. The prototype survives at the Central Museum of the Aif Forces at Monino near Moscow.
