Armament 81 mm M252 mortar and similar weapons. Development By US Army Ordnance as improvement of previous versions. Description This is the Americanised version of the M889, which consisted of changing the body from cast to forged steel and utilising standard component parts (fin, propulsion and ignition systems and packaging) to increase commonality. The complete round consists of a fuze, increment charges, fin assembly, ignition cartridge, and shell body. The shell body, made of forged steel material, is loaded
with a Composition B (RDX/TNT) filler. The ignition cartridge has a percussion primer and is assembled to the end of the fin assembly. The propellant charge is contained in four horseshoe felt-fibre containers and assembled around the fin assembly shaft. This round cannot be fired in Low or medium pressure mortars. It is similar to the Mecar M512 HE bomb.
