N1 Nuclear AF
Part of N1 Family
Russian nuclear orbital launch vehicle. A variant of the first alternative considered in the 1963 nuclear N1 study. This was a 'high thrust' version of the Type A engine - apparently with higher propellant rate, lower specific impulse, and lower engine weight. Due to the very low density of the enormous liquid hydrogen upper stages, these immense vehicles would have been very ungainly (and had interesting stress problems during ascent!)

Status: Study 1963. Payload: 300,000 kg (660,000 lb). Thrust: 35,000.00 kN (7,868,000 lbf). Gross mass: 2,500,000 kg (5,500,000 lb). Height: 200.00 m (650.00 ft). Diameter: 17.00 m (55.00 ft). Apogee: 220 km (130 mi).

LEO Payload: 300,000 kg (660,000 lb) to a 220 km orbit at 51.60 degrees. Payload: 27,100 kg (59,700 lb) to a lunar surface.
