N1F-L3M
Part of N1 Family
N1M - Sr
N1M - Sr
Russian heavy-lift orbital launch vehicle. The N1M was found to be too ambitious. The N1F of 1968 was instead penciled in to be the first Soviet launch vehicle to use liquid oxygen/liquid hydrogen high energy cryogenic propellants. The N1F would have only used the Block S and Block R fourth and fifth stages in place of the N1's Block G and Block D.
