OPS-4 is an unflown Soviet space station, expected to be a fourth in the secret Almaz military program. It remained grounded due to the cancellation of the program.
OPS-4 underwent several technical and design changes. The aft docking port was designed to receive heavier TKS spacecraft, compared to a lighter Soyuz-enabled docking port in the three previous stations.
It was to be the first station launched with a three panel Mech-A Synthetic Aperture Radar and a manned reusable Return Vehicle VA. The VA was replaced by a second docking port, due to delays in preparing a crew-rated TKS; the front section was refitted with a Soyuz-enabled docking port to receive manned craft.
In terms of payload, the optical reconnaissance instruments carried by the previous Almaz stations were to be replaced aboard OPS-4 with radar and electronic intelligence hardware onboard. Also, the infamous self-defense gun onboard early Almaz was to be replaced with two anti-satellite missiles from the Shield-2 system.
