Use in Hungary The Hungarian People’s Army acquired the first S-60 cannon in 1959. The cannon served as a light anti-aircraft weapon in the anti-aircraft artillery units of the motorised, mechanized, and tank divisions, in the direct anti-aircraft artillery units of the ground forces, and in the air defence artillery units. The cannon and its fire-control system was produced in Hungary at the Diósgyőri Machine Factory from 1959 until the 1980s.
