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!)
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.

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...
