The Rheinmetall Mk 20 RH-202 (short for MaschinenKanone 20 mm Rheinmetall) is a 20 mm caliber autocannon designed and produced by Rheinmetall. It fires the 20×139mm ammunition originally developed for the Hispano-Suiza HS.820. The cannon is used on German military vehicles including 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. A towed twin mount antiaircraft version was also produced; it was used by Argentina in the Falklands War. 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. A version modified to fire the U.S. M50 series of 20×102mm 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.[1] Variant: 20 mm twin anti-aircraft mount{{Infobox weapon|name=Flugabwehrkanone 20 mm Zwilling | image= 20 mm anti-aircraft gun of the Bundeswehr.JPEG | image_size = 300 |caption=20 mm twin gun 1095 of the German Air Force. |origin= West Germany |type=Autocannon |is_ranged=YES |is_bladed= |is_explosive= |is_artillery=YES |is_vehicle= |service= |used_by= |wars= |designer=Rheinmetall |design_date=1960s |manufacturer=Rheinmetall |production_date= |number= |variants= |weight=1,640 kg (combat ready)[2] 2,050 kg (travelling) |length={{convert|5|m|ftin|abbr=on}} (travelling) |part_length={{convert|1.8|m|ftin|abbr=on}} |width={{convert|2.3|m|ftin|abbr=on}} (travelling) |height={{convert|2|m|ftin|abbr=on}} (travelling)[3] |crew=3 to 4 |cartridge=20 × 139 mm |caliber=20 mm[2] |action=Gas unlocked blowback |rate=880 to 1,030 rpm per gun[2] |velocity=1,044 m/s with HEI 1,100 m/s with AP |range=1,600 m against high flying aircraft[2] 2,500 m against ground targets[2] |max_range= |feed= |sights= |breech= |recoil= |carriage= |traverse=360°[2] |elevation=-5° to +83.5°[2] |blade_type= |hilt_type= |head_type= |haft_type= |diameter= |filling= |filling_weight= |detonation= |yield= }} 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. This gun 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. Operators
