ASCC codename: Bounder
Strategic Bomber Prototypes

Though it never entered service, the Myasishchev M-50 was a highly advanced design for a large, supersonic intercontinental bomber. The M-50 was considered top secret by Soviet leadership and very little is known about the project even today.

The Myasishchev design bureau began work on the M-50 concept in 1956. The M-50 was designed to carry the long-range M-61 cruise missile also under development by Myasishchev at the time. A key element of the M-50 design was its engines, originally intended to be advanced powerful turbojets built by Zubets. Development problems delayed these engines, so the first M-50 prototype was instead equiped with less powerful VD-7 turbojets mounted two beneath the wing and one at each tip of the large cropped-delta wing. The long-slender fuselage provided accomodation for two or three crew members and a large weapons bay. The fuselage also incoporated the area-rule to reduce transonic drag. The first M-50 prototype, with its substitute engine installation, served as a technology demonstrator and was capable of a maximum speed of Mach 0.99.

The second prototype, redesignated the M-52, was equipped with the more advanced engines that doubled the maximum speed to Mach 1.83. Despite this progress, the M-52 program failed to impress Soviet leaders who had become convinced that manned bombers were obsolescent following the development of ballistic missiles. As a result, the M-50/M-52 project was cancelled and the Myasishchev design bureau closed in 1960. A surviving example of the impressive M-50 is now on display at the Monino Aviation Museum in Moscow.
