In-Bore Premature Malfunction Investigations of the 81mm High Explosive Mortar Cartridges with the M526, M524A5 and XM716 Point Detonating Fuzes

Abstract

A series of malfunction investigations were conducted to determine the causes of in-bore prematures of various types of 81mm ammunition. Tests indicated that in-bore prematures can result from missing bore riding pin, double loading, voids in high explosive (HE) filler, porosity in shell body or loose base plugs. It was also found that Mk1 and Mk2 Navy Mortars are of marginal design, and that M362, M370, M374 and M375 Cartridges should not be fired above Charge 5 with these weapons.
