Military Soyuz

[3] The Soyuz-R system (1963-1966) consisted of two separately launched spacecraft, including the small orbital station 11F71 with photo-reconnaissance and electronic intelligence equipment and a Soyuz 7K-TK for crew transport.

Zvezda would be powered by two plutonium radioisotope thermoelectric generators, as solar arrays required the spacecraft to be position to the sun, not a desired attack mode.

The cosmonaut group selected included commander Pavel Popovich, pilot Alexei Gubarev, flight-engineers Yuri Artyukhin, Vladimir Gulyaev, Boris Nikolaevich Belousov, and Gennadiy Kolesnikov.

[8] The initial Soyuz 7K-S program was to consist of four uncrewed, followed by two crewed test flights, then two operational launches.

At that time the launch escape system for 7K-S was ready and was used for Apollo-Soyuz Test Project flights.

Three complete vehicles were launched as uncrewed test missions: The Soyuz 7K-ST transport project was develop in parallel to the military 7K-S and was redesigned for a crew of three, eventually becoming the Soyuz-T used with the Salyut space stations.
