Russian manned lunar flyby spacecraft. Cancelled 1965. The LK-1 was the spacecraft designed by Chelomei for the original Soviet manned lunar flyby project. The re-entry vehicle and propulsion systems would continue in development for the LK-700 lunar lander and TKS space station resupply vehicle.

Status: Cancelled 1965. Gross mass: 17,000 kg (37,000 lb). Unfuelled mass: 4,000 kg (8,800 lb). Height: 5.20 m (17.00 ft). Span: 7.27 m (23.85 ft).

In October 1965 Korolev managed to get the project cancelled and started development of his Soyuz 7K-L1/Block D spacecraft in place of the LK-1.

Design was said to have been ordered informally by Khrushchev on 13 May 1961 in response to the American Apollo program. In fact the LK-1 had its basis in a family of manned and unmanned vehicles that reached the draft project stage in the 1961-1963 period under the generic names of kosmoplans and raketoplans.

Authorization to proceed with development of the three-stage UR-500K launch vehicle and the LK-1 itself was finally included in the omnibus 3 August 1964 lunar project decree. By that time design had been completed. 12 were to be built in 1965 to 1966 with first flight in 1967.

At launch the spacecraft consisted of the following modules:

The LK-1 would be placed into a parking orbit of the earth by the UR-500K Proton launch vehicle. With proper optimization of the Proton booster based on early flight tests, it was felt that the LK-1 would ultimately be capable of carrying two cosmonauts.

The capsule of the LK-1 was developed further. It was proposed to be used on Chelomei's LK-700 lunar lander and TKS space station resupply ship. The TKS flew in the 1970's, but never in a manned flight.

Crew Size: 1. Spacecraft delta v: 3,300 m/s (10,800 ft/sec). Electric System: 2.00 average kW.

Chelomei LK-1 circumlunar spacecraft. The 2.8 m diameter Apollo-type re-entry capsule was mounted atop a cylindrical service module, which provided power and boosted the spacecraft on a translunar trajectory. The large solar panels would have provided considerably more power than Korolev's competing Soyuz 7K-L1 configuration.
