Line drawing of an Almaz space station Almaz space station at VDNKh (Russia) The Almaz (Russian: Алмаз, lit. 'Diamond') program was a highly secret Soviet military space station program, begun in the early 1960s. Three crewed military reconnaissance stations were launched between 1973 and 1976: Salyut 2, Salyut 3 and Salyut 5.
Salyut 3 (Russian: Салют-3, lit. 'Salute 3', also known as OPS-2 [1] or Almaz 2 [2]) was a Soviet space station launched on 25 June 1974. It was the second Almaz military space station, and the first such station to be launched successfully. [2]
Salyut 2 was an Almaz military space station. [2] It was designated part of the Salyut programme in order to conceal the existence of the two separate space station programmes. [3] Salyut 2 was 14.55 metres (47.7 ft) long with a diameter of 4.15 metres (13.6 ft), [4] [5] [6] and had an internal habitable volume of 90 cubic metres (3,200 cu ft).
Salyut 5 (Russian: Салют-5 meaning Salute 5), also known as OPS-3, was a Soviet space station. Launched in 1976 as part of the Salyut programme, it was the third and last Almaz space station to be launched for the Soviet military. Two Soyuz missions visited the station, each crewed by two cosmonauts. A third Soyuz mission attempted to ...
The Almaz-OPS space station cores were designed in October 1964 by Vladimir Chelomey's NPO Mashinostroyeniya (OKB-52) organization as military space stations, long before the Salyut programme started. [2] For Salyut, small modifications had to be made to the docking port of the OPS to accommodate Soyuz spacecraft in addition to TKS spacecraft.
OPS-4 is an unflown Soviet space station, expected to be a fourth in the secret Almaz military program. It was initially planned for launch in late 1977, but delays in readiness of the TKS spacecraft caused this date to be shifted. By December 1978 cosmonauts were training for OPS-4 with an estimated launch date of December 1980, but the Almaz ...

At the aft end a pilot station was equipped with controls and windows for manual docking with the Almaz space station. The docking port was also located here. Operational TKS spacecraft would have delivered KSI film return capsules to Almaz stations. These would have been stored around the docking port for transfer to the film capsule airlock ...
