{{main|Salyut 2}}
The first Almaz station (OPS-1 or Almaz 101.1) was launched on April 3, 1973. For purposes of military secrecy, it was publicly designated [[Salyut 2]] upon reaching orbit. A crew was prepared to fly to the station, but an accident days after the launch left OPS-1 disabled and depressurized.<ref name="rsw-almaz-ops1">{{Cite web |last=Zak |first=Anatoly |title=Short mission of Almaz-1 - OPS1 (Salyut-2) |url=https://www.russianspaceweb.com/almaz_ops1.html |url-status=live |archive-url=https://web.archive.org/web/20240415065630/https://www.russianspaceweb.com/almaz_ops1.html |archive-date=April 15, 2024 |access-date=July 6, 2012 |website=RussianSpaceWeb.com }}</ref>

OPS-2 (or Almaz 101.2), announced as [[Salyut 3]], was launched on June 25, 1974. The crew of the [[Soyuz 14]] spacecraft spent 15 days aboard the station in July 1974. A second expedition was launched toward OPS-2 in August 1974, but failed to reach the station. The station successfully remotely test-fired an onboard aircraft [[autocannon|cannon]] at a target satellite while the station was uncrewed. Salyut-3 was deorbited in January 1975.<ref name="astrospies">{{Cite web |last=Bamford |first=James |title=Astrospies |url=https://www.pbs.org/wgbh/nova/astrospies/ |url-status=live |archive-url=https://web.archive.org/web/20240501065844/https://www.pbs.org/wgbh/nova/video/astrospies/ |archive-date=May 1, 2024 |access-date=July 6, 2012 |website=[[Nova (American TV program)|NOVΛ]] |publisher=[[PBS]] }}</ref>
