Class: Manned. Type: Rocketplane. Nation: USSR. Manufacturer: Biesnovat.

Biesnovat was assigned the project to develop an all-Soviet equivalent to the 346 supersonic rocketplane being developed by the German Roessing team in OKB-2. Like the 346, the 5 was a swept-wing aircraft, but about 2/3 the size. First glide flight by A K Pakhomov, dropped from a Pe-8, came on 14 July 1948. The first 5-1 aircraft was destroyed on its third flight 5 September 1948. The 5-2 second aircraft, with rocket engine installed, made its first flight on 26 January 1949. After five unpowered flights, the program was cancelled in June 1949. By that time better-funded turbojet-powered fighter prototypes were already achieving the 1200 km/hr top speed of the 5. Biesnovat and Isayev would elaborate the design in unmanned form into the supersonic R-1 air-to-surface missile.
