LK-700 was an proposed Soviet direct ascent lunar lander program proposed in 1964.[1] 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[2] 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.[3] The program was canceled in 1974.

Mission profile[edit]

Unmanned flights would be followed by manned flights. The proposed schedule was:

  • May 1972: First UR-700/LK-700 unmanned launch. Subsequent launches in November 1972 and April 1973
  • April 1973: First manned UR-700/LK-700 launch. Subsequent flights in August and October 1973.

Following initial LK-700 landings, the more ambitious Lunar Expeditionary Complex (LKE) would be delivered to the surface in three UR-700 launches:

  • Launch 1: lunar station to enable a six month's stay
  • Launch 2: LK-700 with crew
  • Launch 3: large rover
