The Soyuz 7K-LOK, or simply LOK (Russian: Лунный Орбитальный Корабль, romanized: Lunniy Orbitalny Korabl meaning "Lunar Orbital Craft") was a Soviet crewed spacecraft designed to take humans from Earth to orbit the Moon, developed in parallel to the 7K-L1. The LOK would carry two cosmonauts, acting as a mother ship for the LK lander which would land one crew member to the surface. It was part of the N1-L3 programme which also included the LK lander and the N1 rocket.
