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.
