By the end of the 40s, with the advent of nuclear weapons, there was a need for means of delivering them. Bombers with characteristics exceeding serial production by 1.5 - 2 times were needed. I. Stalin decided to entrust V. Myasishchev with the development of the aircraft, but limited it to very tight deadlines. March 24, 1951 By a resolution of the Council of Ministers of the USSR, the construction of a strategic bomber is entrusted to the MAP OKB-23, again recreated after closure. V. Myasishchev is appointed chief designer. In June, the Air Force Commander-in-Chief approved tactical and technical requirements that determined the following main characteristics of the M aircraft: the maximum range with a bomb load of 5 tons should be at least 11000 - 12000 km, and the speed at an altitude of 9000 m - 900 kmh.
