The fourth stage of the N1-L3 lunar landing complex, was designated Block G. During the lunar expedition, Block G equipped with a single engine burning a mix of kerosene and liquid oxygen, would send the L3 expeditionary complex from low-Earth orbit toward the Moon. During this maneuver, the propulsion system onboard Block G was to burn until full consumption of the propellant onboard the stage. Sergei Korolev's OKB-1 was responsible for the overall development of Block G, while OKB-276, based in Kuibyshev and led by Nikolai Kuznetsov developed the propulsion system for the stage.
