The K-23 submarine was a Soviet Project 667A Navaga nuclear-powered ballistic missile submarine. Launched in 1960, it was part of the Soviet Navy's efforts to enhance its strategic deterrent capabilities during the Cold War. The K-23 was equipped with R-27 submarine-launched ballistic missiles, allowing it to strike targets from underwater. This submarine was notable for its advanced technology at the time, including a double-hull design that improved its stealth and survivability. The K-23 served in various capacities until it was decommissioned in the late 1980s, reflecting the changing dynamics of naval warfare and military strategy.
