Myasishchev M-50 Bounder
The Myasishchev M-50 (NATO reporting name Bounder) was designed as a supersonic bomber capable of reaching the Continental United States. Although flown successfully, only one flying prototype was completed. An additional airframe designated M-52 was completed but not flight tested.
The Myasishchev M-50 was powered by four engines: two Dobrynin VD-7 non-afterburning turbojet engines at the outer and two VD-7F afterburning turbojet engines at the inner positions. The two inner engines were located under the wing, and the two outer on the wingtips of its shoulder-mounted, truncated delta wings.
The M-52 differed from the M-50 in seating the crew side by side, rather than in tandem. Additionally the tail was redisigned. Its planned engines were to be four Zubets 16-17 turbofans.
The development of intercontinental ballistic missiles proved to be a more reliable method of delivering nuclear warheads and M-50 development was cancelled.
