. Following launch, it would have docked with the NO docking module of a waiting Soyuz 9K, and transferred over of fuel into the tug. Up to three Soyuz 11K tankers would have been launched per Soyuz 9K, each one carrying either propellant or oxidiser. The Soyuz 9K would then have been used to boost a crewed Soyuz 7K or Soyuz 7K-P spacecraft into a higher orbit; the Soyuz 7K onto a circumlunar trajectory for human Lunar exploration, and the Soyuz 7K-P into a higher orbit to intercept and destroy another spacecraft. The Soyuz 11K, along with the NO module of the Soyuz 9K, would have been jettisoned before the Soyuz 9K performed its burn. Following the cancellation in 1964 of both the Soyuz 7K and Soyuz 7K-P programmes; the former in favour of the

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, with the first flight planned for 1967. The LK-1 had ...
