In the definitive December 1962 Soyuz draft project, the Soyuz B (9K) rocket acceleration block would be launched into a 225 km orbit by a Soyuz 11A511 booster. Following refuelling by tone to three Soyuz V (11K) tanker spacecraft, a manned Soyuz spacecraft would rendezvous and dock with the 9K. It would then be boosted on its mission (circumlunar, satellite intercept, or high earth orbit).

The 9K would be followed in orbit by one to three Soyuz V 11K tankers (depending on the mission), which would automatically rendezvous and dock with the 9K. They would transfer up to 22 tonnes of propellant. Finally the 7K spacecraft with the cosmonauts aboard would be launched and dock with the 9K. The 9K would then be used to put the 7K on its mission. This could be either a Soyuz-A on a circumlunar flight or a Soyuz-P on satellite intercepts at up to 6,000 km altitude.

The 11K was authorised for development by a subcontractor, but soon both the Soyuz-A and Soyuz-P were cancelled. On 3 August 1964 it was decided tht Chelomei would develop his LK-1 for the manned lunar flyby in place of the Soyuz-A. The Soyuz-P was cancelled when manned satellite intercept was found to be impractical.

Some of the docking and propellant transfer technology of the Soyuz V undoubtedly was applied to the Progress space station resupply spacecraft of the 1970's.
