An orbital platform for reconnaissance
The Soviet Almaz program grew from military interest in observing Earth from orbit. Vladimir Chelomei’s design organization developed a station concept in which cosmonauts could operate reconnaissance equipment and conduct supporting work. A station, transport spacecraft, launch vehicles and ground infrastructure were parts of the intended system.
Human presence offered a proposed ability to select and manage observations, but it also required life support, crew training and a return route. Evaluating that approach means comparing the observation need with the full system required to support people. The military purpose should be stated directly without treating every experiment aboard as the same activity.

Three stations used Salyut designations
Almaz stations flew under the public names Salyut 2, Salyut 3 and Salyut 5. Salyut 2 failed before a crew occupied it. Salyut 3 and Salyut 5 supported crewed missions during the 1970s. These outcomes differ from the civilian Salyut line even though the public naming scheme placed them in one numbered series.
Soyuz spacecraft transported the crews on the actual station expeditions. The larger TKS transport was developed for the broader Almaz concept, but it did not carry people to these stations. A diagram of the intended complete system must therefore distinguish the proposed transport arrangement from the vehicles used on completed missions.
Almaz: intent and actual transport
Original teaching diagram. Station flights. Salyut 2: failed before occupation. Salyut 3 and 5: crewed operations. Transport distinction. Soyuz carried the station crews. TKS developed; no crewed TKS flight. The public Salyut label does not erase the military Almaz program identity.

A legacy with more than one branch
The crewed Almaz station effort ended, while related work continued through uncrewed observation systems and transport-derived hardware. Those later branches should retain their own configurations and dates. An uncrewed radar spacecraft is not simply an occupied Almaz station with its crew hidden from the public.
Almaz also contributed structures and development experience to the broader history of Soviet stations. Connections do not erase institutional differences: a shared structural ancestry can support different objectives, payloads and operating models. Compare Almaz with the unflown U.S. MOL by asking which systems actually flew and which mission goals remained proposals, rather than assuming all military station programs had identical outcomes.
