Russian nuclear-powered orbital launch vehicle. First large space launcher considered in the Soviet Union. It would have had the same layout as the R-7, but with six strap-ons increased in size by 50%. The core, igniting at altitude, used a nuclear thermal engine using ammonia as propellant. Dropped in favor of development of conventional chemical propulsion.

Status: Cancelled 1949. Payload: 40,000 kg (88,000 lb). Thrust: 12,422.80 kN (2,792,757 lbf). Gross mass: 888,000 kg (1,957,000 lb). Height: 44.00 m (144.00 ft). Diameter: 3.33 m (10.92 ft). Apogee: 185 km (114 mi).

LEO Payload: 40,000 kg (88,000 lb) to a 185 km orbit.
