<h2>Armament</h2><p>Mauser MK 30 cannon series; 30 mm GAU-8/A Avenger gun system; 30 mm Bushmaster II ; Goalkeeper CIWS; SAMOS CIWS; Artemis 30 mm air defence system; Arrow twin 30 mm air defence system; Otobreda Single 30 and Twin 30 naval mountings.</p><h2>Development</h2><p>The 30 × 173 mm Mauser round is based on the 30 × 173 mm Oerlikon Contraves round and was adopted for the Mauser MK 30 cannon. MK 30-1 cannon are intended for naval applications, while MK 30-2 cannon are intended for land systems, such as infantry and armoured vehicle armament . The range of General Dynamics Ordnance and Tactical Systems (formerly PRIMEX Technologies, Olin Ordnance and before then Aerojet) 30 × 173 mm air defence ammunition was developed for use with the Artemis 30 mm air defence system . For details of the ammunition for this system refer to separate entry in this section The German Arrow twin 30 mm air defence system was developed for the Royal Thai Air Force. This 30 × 173 mm ammunition is based on the GAU-8/A family but features significant improvements and could be fired from all existing GAU-8/A compatible cannon. Well over 400,000 rounds of 30 × 173 mm ammunition have been produced by PRIMEX for various international customers utilising the Mauser cannon. A team of Mauser and Oerlikon-Contraves Pyrotec AG are developing a 30 × 173 mm subcalibre family specifically for the Bushmaster II and Mauser MK 30 cannon. See separate entry for available details.</p><h2>Description</h2><p>All 30 × 173 mm MK 30 rounds are fixed, with their streamlined projectiles secured to aluminium cartridge cases by a single cannelure and with a single wide plastic drive band encircling the projectile body just above the case/projectile joint. The necked cases are rimless and have a percussion primer in the base. Cartridge cases may be aluminium or steel: the Mauser Model MK 30-1 fires aluminium cartridge-cased ammunition while the MK 30-2 fires steel cases. There are three ballistically matched projectiles in the family; APDS-T, HE-I/SD-T and TP-T. The APDS-T projectile has a blunt hollow nose with a glass-filled nylon sabot body enclosing a subcalibre tungsten penetrator. The sabot falls away from the penetrator soon after the projectile leaves the muzzle. A thin light-alloy windshield then provides ballistic efficiency for the blunt-nosed subcalibre penetrator, which is claimed to be capable of defeating twice the armour thickness of the full calibre 30 mm GAU-8/A API projectile at a range of 1,500 m. Muzzle velocity of the APDS-T projectile is 1,225 m/s and time of flight to 2,000 m is 1.87 seconds. Compared to the APDS-T, the HE-I/SD-T projectile has a more conventional streamlined profile and high-fragmentation steel body, with a point impact fuze screwed into the nose. The nose fuze contains a self-destruct element which functions after 7.9 seconds, while the projectile base contains an extrusion housing the tracer element. Muzzle velocity of the HE-I/SD-T projectile is 1,035 m/s and time of flight to 2,000 m is 2.96 seconds. The TP-T is a low-cost training round ballistically matched to the HE-I/SD-T. A ballistic windshield replaces the normal nose fuze and there is provision for an optional impact flash spotting charge. The tracer element is housed in a machined cavity in the projectile base. Mauser-produced rounds for the MK 30 and the German Arrow twin-barrelled air defence system include HE-I/SD-T, MP-T, SAPHEI-T, APDS-T, APFSDS, and TP or TP-T.</p><h2>Authorised fuzes</h2><p>No information available Equivalent rounds SWITZERLAND</p><p>SWITZERLAND</p><h2>Manufacturer</h2><p>Oerlikon Contraves Pyrotec AG</p><p>Type: FAPDS-T, APFSDS-T</p><p>Description: See separate entry</p>
