It was the Soviet counterpart of the American Saturn-V The rocket N1 was a titanic feat of engineering consisting of 5 stages' Its first stage involved a cluster of 30 high-powered rocket engines using kerosene and liquid oxygen as fuel.
However, the development of a heavy-lift launcher, needed for the lunar expedition, was plagued with political and technical problems. The N-1 Moon Rocket was replaced by the Energia Booster The Energia Booster used modified N-1 launch pads.
