Soyuz 15 (Russian: Союз 15, Union 15) was a 1974 manned space flight which was to have been the second mission to the Soviet Union's Salyut 3 space station with presumably military objectives.[2]
Launched 26 August 1974, the Soyuz spacecraft arrived at the station, but cosmonauts Lev Dyomin and Gennadi Sarafanov were unable to dock because of a fault in the automated docking system. Without sufficient fuel for prolonged attempts at manual docking, the mission had to be abandoned.[3] The crew landed 28 August. Analysis of the launch window was cited by observers for concluding a flight of 19 to 29 days had been planned.[3]
It was later claimed by Soviet authorities that no docking had been intended and that the flight had been undertaken merely to develop techniques for maneuvering near the space station.[2] They also said that a new automatic docking system was tested which would be used on future Progress transport craft.[3]
