The Myasishchev M-50 was a Soviet prototype four-engine supersonic bomber which never attained service. Only one prototype was built which was believed to have first flown in 1957. The M-50 was constructed by the Myasishchev design bureau. It was a fast jet bomber with four engines: two Dobrynin VD-7 and two VD-7F turbojets. Two engines were located under the wing and two on the tips of its shoulder-mounted truncated delta wings.
