LK-1

LK-1 was a projected Soviet crewed lunar flyby spacecraft. It would be launched on a three-stage Proton launch vehicle. The project started in 1962 under the lead engineer Vladimir Chelomey,[1] with the first flight planned for 1967.

The LK-1 had its origin in several early 1960s spacecraft projects under the generic names of kosmoplans and raketoplans.[2]

In 1965 the project was cancelled in favour of the Soyuz 7K-L1 spacecraft.[2]

Further developments came as the LK-700 direct-descent lunar lander program.

Configuration
An drawing of a VA spacecraft: The VA capsule is on the lower right, while the braking engines are located on top of the long "nose section".[3][4] The launch escape system (not shown) would have been attached on top of the nose section.[5]
