Abstract : An enclosure for a warhead case which prevents a high order detonation of the warhead due to inadvertent initiation from physical, bullet, fragment impact, fire exposure or other factors causing a pressure buildup in the case. The warhead explosive is assembled in a hollow cylindrical warhead case having an open end and a closed end. An enclosure plate is positioned in the open end to close off the warhead in the case. The enclosure is circular and provided with a first plurality of radially extending apertures. The warhead case is provided with a second plurality of radially extending apertures which are positioned to coincide with the aperture in the enclosure plate. A plurality of pins are press fit into the case apertures so as to extend into the enclosure plate apertures and attach the enclosure plate to the warhead case. The pins are intended to fail structurally when the internal pressure of the warhead case reaches a predetermined threshold so as to remove the enclosure plate and relieve any pressure buildup that may cause a high order detonation of the warhead.
