Rheinmetall Rh 202
The cannon is used on military vehicles of German origin, like the Marder infantry fighting vehicle, the Spähpanzer Luchs and some variants of the Wiesel AWC. It is also used in the Argentinian VCTP, an IFV based on the TAM chassis.
German naval ships also employed Rh 202 mounts (usually two on frigates and destroyers, four on larger replenishment ships), but they have been or are currently being replaced with the new Mauser (now a subsidiary of Rheinmetall) MLG 27 remote controlled guns of 27 mm calibre.
The gun modified to fire the U.S. M50 series of ammunition loaded into the M14 link belt has been offered to no avail for the U.S. Government by Maremont Corp., of Saco, Maine, licensed by Rheinmetall under marketing arrangement.

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.
