Ammunition for 84 mm Carl Gustaf recoilless guns

case is closed at the rear by a plastic baseplate. Rounds are normally issued and carried in two-round plastic-based containers. Ammunition development is still continuing for the 84 mm Carl Gustaf; only the current production versions are mentioned here. The following types of round are available: 84 mm HE 441B The projectile used with the 84 mm HE round has an unusual shape. The rounded nose is actually a 447 combined MT and impact fuze with the thin-walled shell body having a pronounced boat tail base with a rounded end. The steel body encloses two neoprene rubber inserts, each containing approximately 800 steel spheres that considerably add to the fragmentation effects produced when the 400 g RDX/TNT filling is detonated. The round has a dual-mode fuze function with the Instant or Delayed mode selected at the instant of loading by the orientation of the cartridge case with the firing mechanism. Markings on the base (I and D) signify the correct alignment. The shell body is manufactured from high-fragmentation steel, and is surmounted by an aluminium nose cap covering the shaped charge liner which is of a 'special material' ensuring behind-armour effects. The explosive charge is 580 g of HMX/TNT with a pressed tetryl and RDX booster. An aluminium alloy fin assembly with six fins is located behind the shell body. The fins are folded forward inside the cartridge case and are unfolded once the projectile leaves the gun muzzle by using residual propellant gas pressure retained by a plunger arrangement. The integral fuze system is a combination piezoelectric impact or pyrotechnic delay arrangement, with the mode selected by the orientation of the cartridge case.
