N-IMV-II,III
N-IMV-II,III
Russian heavy-lift orbital launch vehicle. N-IMV-II, III was the ultimate conventionally-powered N1 ever considered. It paired the monster N-1M first stage with new cryogenic second and third stages. Both liftoff thrust and payload of this vehicle would have been double that of the American Saturn V.
LEO Payload: 230,000 kg (500,000 lb) to a 220 km orbit at 51.60 degrees.
Status: Study 1965.
Gross mass: 5,200,000 kg (11,400,000 lb).
Payload: 230,000 kg (500,000 lb).
Height: 165.00 m (541.00 ft).
Diameter: 17.00 m (55.00 ft).
Thrust: 74,000.00 kN (16,635,000 lbf).
Apogee: 220 km (130 mi).

N1 The N1 launch vehicle, developed by Russia in the 1960's, was to be the Soviet Union's counterpart to the Saturn V. The largest of a family of launch vehicles that were to replace the ICBM-derived launchers then in use, the N series was to launch Soviet cosmonauts to the moon, Mars, and huge space stations into orbit. In comparison to Saturn, the project was started late, starved of funds and priority, and dogged by political and technical struggles between the chief designers Korolev, Glushko, and Chelomei. The end result was four launch failures and cancellation of the project five years after Apollo landed on the moon. Not only did a Soviet cosmonaut never land on the moon, but the Soviet Union even denied that the huge project ever existed. More...
