Salyut 2 was an Almaz military space station. It was designated part of the Salyut programme in order to conceal the existence of the two separate space station programmes.
Salyut 2 was 14.55 metres (47.7 ft) with a diameter of 4.15 metres (13.6 ft), and had an internal habitable volume of 90 cubic metres (3,200 cu ft). At launch it had a mass of 18,950 kilograms (41,800 lb). A single aft-mounted docking port was intended for use by Soyuz spacecraft carrying cosmonauts to work aboard the station. Two solar arrays mounted at the aft end of the station near the docking port provided power to the station, generating a total of 3,120 watts of electricity. The station was equipped with 32 attitude control thrusters, as well as two RD-0225 engines, each capable of generating 3.9 kilonewtons (880 lbf) of thrust, for orbital manoeuvres.
