The design of Salyut orbital stations

It is shown that, despite a general assumption to the contrary, the civilian and military Salyuts are externally of a totally different design. The only similarity is the mass (approximately 19 tons) and the launch vehicle used (a Proton D-1). Among the differences are that solar panels on the military version are placed farther aft than on the civilian version and that military Salyuts carry a data return capsule.
