30 x 113 B ammunition for Aden guns (Norway), Cannon - 20 to 30 mm cannon Development The Mauser MG 213C revolver cannon had a profound effect on European aircraft gun designers in the years following 1945 and led to the development of both the Aden and DEFA 30 mm revolver cannon and associated ammunition as described in "Introduction to 30 × 113 B ammunition". The 30 mm Aden gun has been in UK service for over 50 years, its final production version being the Mk 4. It was fitted to a wide variety of different aircraft but now only remains in British service in an optional gunpod for the RAF's Hawk trainer, following the retirement of both the Jaguar and Sea Harrier combat aircraft in recent years. Ammunition for the 30 mm Aden, designated DEFA/A, is manufactured by Nexter for foreign customers, mainly in the Middle East. It uses a 113 mm steel case which is coated with an electrolytic zinc plating. It may by fitted with either 24V (cartridges types 5468 and 2468, primer Mle 52 as in DEFA rounds) or 50V primer (cartridges types 5459 and 2469, primer Mle 78) depending on the customer. Only two loadings are in production: TP model 2468 or 2469 and HEI model 5478 or 5479 (the designations depending on the type of primer).Nammo Raufoss AS of Norway produces a 30 mm MultiPurpose (MP) round for firing from Aden cannon. Description All 30 mm Aden gun rounds are fixed, with the projectiles rigidly crimped to their J-type brass cartridge cases, lacquered-steel cases have also been used.
