A disposable EOD dearmer (10) includes an propellant charge (36) permanently affixed to a tubular body (14) for propelling a dearmer slug (40) against a dud casing (12). The pressure versus time characteristic (60, 70) of the charge can be selected to provide a preselected velocity for the slug at impact with the casing, and the initial position (60′, 70″) of the slug can be selected to provide a preselected delay between ignition of the charge and impact between the slug and the casing.

A method of dearming explosive ordnance by disabling a fuze inside a casing thereof comprising the steps of: selecting a open ended elongatged tubular body of lightweight, non-magnetic material; selecting an appropriate charge for the tubular body fore for use against particular ordnance; positioning a dearmer slug in the tubular body bore in front of the explosive charge and at a distance therefrom selected to provide upon detonation of the charge an appropriate pressure build up versus time to provide delay time between detonation of the charge and impact of the slug on the casing; attaching the body to a casing with the open end in the vicinity of the fuze to be disabled; and firing the charge to expell the slug out the open end at a velocity and delay just sufficient to disable the fuze inside the casing of that particular ordnance.
