Armament Objective Crew Served Weapon (OCSW) Development By Primex Technologies to satisfy the US Military OCSW program requirements. Description There are three types of grenade in development for the Objective Crew Served Weapon (OCSW) System: High Explosive (HE), anti-armour and Training Practice (TP). All three rounds are ballistically matched over the entire effective range of the OCSW. The HE round is of the fragmenting airburst type and is derived from the 20 mm Objective Individual Combat Weapon ( OICW )
grenade. The projectile is programmed for range and height of burst by the system fire control as it is launched. The warhead is prescored for uniformity of fragment size and weight and is filled with LX-14 high explosive. Fuzing is electronic and incorporates automatic muzzle velocity correction, along with point detonation and self-destruct capabilities. The anti-armour round utilises a shaped charge of approximately 20 mm diameter for terminal effects and is claimed to be capable of defeating 51 mm of Rolled Homogenous Armour (RHA) in its current configuration, with 51 mm of High Hardness Armour (HHA) as a desired goal. The fuse of the anti-armour round is of the Point Initiating, Base Detonating (PIBD) type. The filler of the anti-armour round is probably RDX. The training practice round is inert. The cartridge casing is aluminium and is of the belted type. It incorporates generally standard `off the shelf' components in its construction, including standard military ball powder, standard primers and a M100 detonator. Manufacturer Primex Technologies
