"In addition to reconnaissance equipment, Almaz was equipped with a unique 23mm Rikhter (factory index 261P or 225P) rapid-fire cannon mounted on the forward belly of the station. This revolver cannon was modified from the tail-gun of the Tu-22 bomber and was capable of a theoretical rate of fire of 1800-2000 (up to 2600) rounds per minute. Each 168 gram (ammo 23-OFZ-D-R ) or 173 gram (ammo 23-OFZ-G-R) projectile flew at a speed of 850 m/s relative to the station. The cannon was tested at the end of the mission by firing 20 rounds, when the station was operating in uncrewed mode. To aim the cannon, which was on a fixed mounting, the entire station would be turned to face the threat. The Almaz series are the only known armed, crewed military spacecraft ever flown."
"The Fractional Orbital Bombardment System (FOBS) was a nuclear-weapons delivery system developed in the 1960s by the Soviet Union. One of the first Soviet efforts to use space to deliver weapons, FOBS envisioned launching nuclear warheads into low Earth orbit before bringing them down on their targets."

"The Polyus spacecraft (Russian: Полюс, pole), also known as Polus, Skif-DM, GRAU index 17F19DM, was a prototype orbital weapons platform designed to destroy Strategic Defense Initiative satellites with a megawatt carbon-dioxide laser. It had a Functional Cargo Block derived from a TKS spacecraft to control its orbit and it could launch test targets to demonstrate the fire control system."
