Three-stage intercontinental boost-glide missile. Studied 1957-1960.

The Tu-130 KR (winged rocket) was a three-stage unmanned boost-glide missile developed at the Tupolev's OKB-156. Work began in 1957. Two alternates were considered for the first stage: a conventional liquid rocket or a special manned aircraft launcher. The second stage was a conventional rocket. The final winged stage included a propulsion section and nuclear warhead. The glider would cut-off at an altitude of 50 km and a velocity of 20,000 km/hr. Planned-over target speed was 7,000 km/hr at 30 km altitude. Work on the project continued only about a year before it was abandoned in favour of the more conventional Tu-123 supersonic cruise missile. The KR would have had a gross weight of 240 tonnes, and delivered a payload of 3 to 5 tonnes over a range of 9,000 to 12,000 km.
