LK-700 was an proposed Soviet direct ascent lunar lander program proposed in 1964. It was developed by Vladimir Chelomey as an alternative to the N1-L3 program. It was also a further development of the LK-1 lunar flyby spacecraft.
It would be launched using the proposed UR-700 rocket (related to the Proton rocket) with a crew of three cosmonauts on a direct flight to the lunar surface and back. The direct landing approach would allow the Soviets to land anywhere on the moon's nearside. The program was canceled in 1974.
