<h2>Armament</h2><p>Giat Industries 30 mm DEFA Series 552/553 guns; Giat Industries 30 mm Series 554 gun; Giat Industries 30 mm Mle 781 (30 M 781) cannon; M230 Chain Gun.</p><h2>Development</h2><p>The French 30 mm DEFA Series 552/553 and Series 554 aircraft guns have the same design origins as the UK 30 mm Aden Guns, namely the Second World War German Mauser 213C revolver cannon. The German gun was taken as the base for what became a series of 30 mm aircraft guns, culminating in the Series 552/553 and 554 guns used in the Dassault Mirage series of strike fighters and other aircraft. Following early French cartridge design forays, international design collaboration with the UK resulted in the  30 × 113 mm B cartridge, which is nominally interchangeable between the DEFA guns and the 30 mm Aden Gun series. However, DEFA cartridges have significant priming and other differences, plus a higher muzzle velocity, which renders them incompatible with the 30 mm Aden gun counterparts. Nammo Raufoss A/S of Norway produces a 30 mm MultiPurpose (MP) round suitable for DEFA cannon. DEFA 30 mm ammunition is in production throughout the world, especially with nations receiving French defence export matèriel. More than 13,500 30 mm DEFA guns have been sold to 40 countries. The latest production model is the 30-550 F4 carried by the Mirage 2000 family. This gun has two rates of fire, 1,800 rds/min for air-to-air combat and 1,100 rds/min for air-to-surface fire missions.</p><h2>Description</h2><p>All 30 × 113 mm B DEFA rounds are fixed with the projectiles rigidly crimped to their J-type thermally treated steel cartridge cases, coated with a self-lubricating lacquer. The cartridge case has a raised belt just above the extraction rim. All projectiles have copper or gilding metal drive bands, although sintered iron may be encountered. Primers are electrical, using a special conductive compound which ensures correct powder ignition whatever the position of the round. The propellant used is approximately 50 g of a nitrocellulose-based multiperforated (19-hole) tubular propellant known as B.19.T and produced by SNPE. DEFA 30 × 113 mm B ammunition may be put into one of three groups; high-explosive, armour-piercing and practice. A further discrimination can be made between ammunition for air-to-air combat and air-to-ground use. Operating temperature limits are from -54 to +74ºC. Firing safety temperature limits are from -60 to +100ºC. Rounds are fed to the revolver loading mechanism on the Series 553/554 guns in belts using pressed steel links. The following 30 mm DEFA ammunition types are those originally produced by Matra Manurhin Defense, later known as Manurhin Defense and now part of Giat Industries. HE-I - type F 7572 Known as a `mine' (Obus Mine Explosif Incendiaire), the round in this air-to-air combat category is the 30 mm type F 7572, which utilises a cold drawn steel, thin-walled, flat-based projectile fitted with a nose-mounted MR3081 short delay fuze with muzzle and rain safety features. The projectile is filled with 50 g of high-temperature tolerant Hexal (RDX/Aluminium). The fuze has a self-destruct mechanism operating between 6 and 15 seconds after firing, using a pyrotechnic chain to time the self-destruct point. The HE-I projectile weighs 245 g, while a complete round weighs 441 g. Muzzle velocity is 810 m/s. The training round used to simulate the air-to-air HE-I is the 30 mm TP-T type F 2570. It is fitted with an inert nose plug, filled with an inert powder and matches the ballistics of the 30 mm HE-I projectiles exactly. Projectile weight is 245 g and the complete round weighs 452 g. There were two earlier versions of the HE-I round, which are no longer in production, the type F 7570 with an ML68 fuze and the HE-I type F 7571 with an MR381 fuze. HEI - type F 2270 This type of HE-I round is used in the air-to-ground role and is provided with a nose-mounted MR3001 impact fuze. At one time this round was known as an APHEI, with the AP referring to anti-personnel. It is filled with 30 g of high-temperature tolerant Hexal (RDX/Aluminium). There is no self-destruct mechanism. The HE-I projectile weighs 275 g, while the weight of a complete round is 490 g. Muzzle velocity is 775 m/s. The training round used to simulate this HE-I is the TP F 2270. It is fitted with an inert nose plug, filled with an inert substance and matches the ballistics of the air-to-ground HE-I projectile exactly. Projectile weight is 275 g and the complete round weighs 490 g. This round is no longer in series production having been replaced by the generally similar type F5272 with a high fragmentation projectile casing for anti-personnel applications. For this round the MR 3001 point detonating fuze is utilised. There are two earlier versions of air-to-ground HE-I round that are no longer in production, the OAPEI type F 5270 with an MRX70 fuze and the OAPEI type F 5271 with an MR31 fuze. SAPHEI type F 7670 Intended primarily for air-to-air combat, this round is known as the 30 mm type F 7670. It uses a thick-walled, heat-treated steel projectile with a blunt nose, covered by a light alloy windshield to retain a ballistic match with other rounds in the DEFA 30 mm family. The base of the projectile is occupied by a delayed action base fuze known as the MR3005, with an arming distance of 20 m from the muzzle and a self-destruct time between 6 and 15 seconds. When the fuze functions it detonates the explosive payload, which weighs 18 g, to create high-fragmentation effects behind the target armour. The projectile can penetrate up to 20 mm of armour. The weight of the projectile used with this round is 275 g and the weight of a complete round is 490 g. Muzzle velocity is 775 m/s. API-T - OPIT This round, no longer produced, is known as the 30 mm Mle 5970, and is intended for the air-to-ground attack of hard targets such as armoured vehicles. The projectile uses a cold drawn steel body with thin sidewalls, carrying a heat-treated special steel blunt nose slug that acts as the armour penetrator. It is capable of piercing approximately 20 mm of armour plate. The projectile nose is covered by a light alloy windshield to retain a ballistic match with the other rounds in the DEFA 30 mm family. The projectile body is filled with 20 g of an incendiary composition and a tracer element is mounted in the projectile base. The projectile used with this round weighs 275 g and the weight of a complete round is 490 g. Muzzle velocity is 765 m/s. This round is no longer in series production. TP-T - OXT This round acts as a general purpose training round for the 30 mm DEFA family. Known as the Mle F3170, it has a thick-walled steel body with an inert nose plug. The interior is hollow and empty and the base is occupied by the same tracer element assembly as that used on the 30 mm API-T (OPIT) Mle F5970. The projectile used with this round weighs 245 g and the weight of a complete round is 490 g. Muzzle velocity is  795 m/s. TP - OXL This round, the type F 2570, has an inert ballasted projectile. TP - OXAS The OXAS Practice round, the type F 2270, was developed to prevent fired training rounds ricocheting into aircraft following low-altitude flight patterns, it is also suitable for use where ground safety areas are restricted. The OXAS projectile has a steel body with a plastic nose cap that separates from the body on impact, thereby allowing the rest of the body to fragment, even at low angles of incidence. The OXAS projectile has the same ballistic characteristics as the SAPHEI combat round. The complete round weighs approximately 475 g and the projectile 275 g. MP Produced by Nammo Raufoss A/S of Norway, this 30 mm MP projectile will function reliably against a 2 mm dural plate at impact angles between 0 and 87º NATO, but will not function against a 0.5 mm dural plate in front of the gun muzzle. No fuze is involved as the MP projectile relies upon a drop safe pyrotechnic ignition train. When impacting against aircraft type targets, the projectiles will detonate approximately 300 mm within the target. The distribution of fragments is approximately 20º on each side of the line of fire; the fragments are heavy and optimised to defeat material type targets. The secondary incendiary effects will ignite JP4 and JP5 or heavy diesel oil in self-sealing tanks. Incendiary and blast effects are contained within the target. The length of the Nammo Raufoss 30 mm MP round is given as 199.88 mm and it weighs 440 g; projectile weight is 245 g. Muzzle velocity is 810 m/s.</p><h2>Authorised fuzes</h2><p>See text Equivalent rounds ARGENTINA</p><p>ARGENTINA</p><h2>Manufacturer</h2><p>Direccion General de Fabricaciones Militares</p><p>Type: HE-I (EINC), HE-I-SD (EINC-AD), AP (SPEINC), TP (EJ)</p><p>Description: Manufacturers are Fabrica Militar `Fray Luis Beltran' of Santa Fe.
