In 1975 during the Cold War, the Soviet Union secretly mounted a 23-millimeter automatic cannon on the orbital station 'Salut-3' and conducted tests in space. This experiment was revealed decades later. The cannon, based on the weaponry of the supersonic bomber Tu-22, was intended as a defensive measure against potential enemy spacecraft rather than for attacking satellites. However, practical challenges arose, such as the need to reorient the entire station for targeting, which made the process slow, and recoil issues that affected the station’s stability. Despite these difficulties, the test was considered successful, marking the first and likely only instance of a cannon being fired in space.
