Cosmos 1100



Cosmos 1100 was a Soviet military satellite launched along with Cosmos 1101 from the Baikonur cosmodrome aboard a Proton rocket. One vehicle reentered and landed after two orbits, the other after one orbit. The top capsule was to have been manned, but the inability to demonstrate two consecutive failure free launches of the Proton/TKS-VA combination made that impossible. This launch successfully demonstrated the reusability of the TKS-VA capusle; the same pair had flown as Cosmos 997/998 on 30 March 1978.

It was a landing capsule of the three crew military TKS transport/resupply spacecraft for the Almaz space station. It was called "our Apollo" by cosmonaut Leonov. After separation of the capsule from the Almaz, the retrorocket assembly at top deorbited the capsule. TKS capsules (VA is the Russian acronym) flew 13 times between 1976 and 1983, ten times in capsule tests, three times as part of the complete TKS spacecraft which docked with the Salyut space stations. They were never flown manned.
