supersonic, it never flew under nuclear power (its main goal was to test the nuclear reactor shielding efficiency), and, moreover, it was developed by the Tupolev Design Bureau, as Myasischev company had lost the competition to develop the prototype. It was deemed successful, but further development dragged because of environmental concerns. When the functional ICBMs appeared, the majority of funding and development effort was shifted into that field, and in the early 1960s the project was stopped. On 9 July 1961, the M-50A made its 19th and last flight, participating at a flypast over the annual Tushino air show. This was the one and only public appearance of the giant, currently displayed at the Monino Museum outside Moscow.
