ks-19

The KS-19 is a Soviet 100 mm anti-aircraft gun, designed in the late 1940s to counter high-altitude bombers. It was widely exported and used by many countries, serving primarily as an air defense weapon but also capable of engaging ground targets.

Developed by the Lyulyev Bureau (OKB-8) in the immediate post-WWII era to counter high-altitude American B-29 bombers, the KS-19 officially entered Soviet service in 1948. The weapon saw extensive combat during the Korean and Vietnam Wars, where it was often paired with SON-9 radar systems to effectively engage enemy aircraft. It was also deployed by Arab coalitions during the Arab-Israeli conflicts and later utilized by both sides during the Iran-Iraq War. Although largely superseded by surface-to-air missiles, the KS-19 remains in limited service with several nations, and Iran has modernized its inventory into the automated Sa'eqeh air defense system.
