N-IF Variants
N-IF Versions, from left: N1-L3; N-IF; N-IUV-III; N-IFV-III; N-IFV-III,II
Russian heavy-lift orbital launch vehicle. The N-IF would be the first follow-on version with increased performance. The first stage engines would be increased in thrust from an average of 150 tonnes to 175 tonnes, and those in the second stage from 150 tonnes to 200 tonnes. The second and third stages would be substantially enlarged.

LEO Payload: 100,000 kg (220,000 lb) to a 220 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...
