Rheinmetall 20 Mm Twin Anti-Aircraft Cannon
Rheinmetall Zwillingsflak twin-gun anti-aircraft system began development in 1968 to meet the requirements of the low-level air defence units of the German Air Force, i.e. "to engage low and very low approaching enemy aircraft with all appropriate means in time to prevent them from firing their weapons or delivering their ordnance, or at least to prevent them from carrying out an accurate attack on an Air Force installation."
The Budget Committee of the Bundestag approved the Zwillingsflak system in December 1969, and serial production began in 1972; the first production systems reached units of the Bundeswehr on October 12 of that year. Rheinmetall delivered the last of these in 1976. It was also used by the Argentine Air Force, including during the Falklands War. Since 1981, it was used by the Portuguese Army and Portuguese Air Force.
