Soyuz 7K-L3

The Soyuz 7K-LOK, or simply LOK ( meaning "Lunar Orbital Craft") was a Soviet manned spacecraft designed to launch men from Earth to circle the moon and developed in parallel to the 7K-L1. The LOK would carry two cosmonauts into orbit around the Moon, acting as "mother" spacecraft for the LK Lander, which would land one member of the crew to the surface. It was part of the N1-L3 programme which also included the LK lander and the N1 rocket.
