N1 Launch Vehicle Family
Credit: © Mark Wade
Russian heavy-lift orbital launch vehicle. It was originally planned the N1 would form the basis of a family of launch vehicles that could replace existing ICBM-derived boosters. The N11 would use the second, third, and fourth stages of the N1. This would give it a lift-off mass of 700 tonnes and a 20 tonne payload into low earth orbit. It could replace Chelomei's Proton launch vehicle in the medium-lift role.
LEO Payload: 20,000 kg (44,000 lb) to a 300 km orbit at 51.60 degrees.

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...
