N1F - Sr - N1F with Sr Lox/LH2 upper stage 5,291 bytes. 79 x 311 pixels.

The N1M was to be the first Soviet launch vehicle to use liquid oxygen/liquid hydrogen high energy cyrogenic propellants. As originally conceived, the advanced propellants would be used in all upper stages. However this more ambitious work was revised. The first proposed launch vehicle to use such stages would by the N1F, which 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.
