Myasischev M-50 "Bounder"
Experimental supersonic bomber that first flew in October of 1959.
Only one M-50 was built. It included innovations such as the use of automation to allow for a two-person cockpit (unusual for such a large aircraft at that time) and management of the center of gravity by moving fuel between tanks.
The M-50 was originally designed to use four Zubets RD-16-17 engines of approximately 18,000 kg thrust each. Because the engines were not available when required, the M-50 was instead equipped with four Dobrynin VD-7BA engines of just under 10,000 kg thrust. The two inboard engines were modified (afterburners added?) to produce up to 14,000 kg thrust.
The M-50 was designed to fly at up to Mach 1.8, but it probably never achieved Mach 1.0.
A variation of the M-50 was later built and was designated the M-52. It had RD-16-17 engines originally planned for the M-50 and a different empennage with a small horizontal wing on top of the vertical stabilizer.
One M-52 was produced, though it appears it was scrapped without ever flying.
