The original draft project prior to 1970 for the N1M-L3M lunar landing complex anticipated use of a two-launch profile. On the first launch a Block R TB braking stage would be put on a translunar trajectory. The TB would place itself in lunar orbit. Next, the manned L3M lunar lander would be launched. This new spacecraft was much larger than the LK, with a mass of 21 tonnes landed on the lunar surface. The L3M would dock, tail-first, with the TB stage in lunar orbit. The RTB would act as a lunar crasher stage. The L3M would separate from the TB just over the lunar surface, then hover to a soft landing. The crew would spend up 16 days on the surface. Following completion of their work, the landing legs would be left behind, and the L3M would launch itself on a trans-earth trajectory. Just before arrival at earth, the crew would enter their Soyuz capsule, separate from the L3M, and make a lifting re-entry into the earth's atmosphere. It was felt that within the existing funding allocation of the original N1-L3 programme, enough N1's would be available to support a series of landings in 1978-1980.

Full go-ahead to develop a liquid hydrogen/liquid oxygen high energy upper stage for the N1F. The multi-engine Block Sr would have a propellant mass of 66.4 tonnes. In July Kuznetsov was given authorisation to design substantially improved versions of the N1 lower stage rocket engines. The N1 that would utilise these engines was designated the N1F and would have a payload to a 225 km orbit of 105,000 kg.
