Abstract

An Insensitive Munitions safety device mitigates the occurrence of a violent response of an anti-armor munition subjected to elevated temperatures. The anti-armor munition includes a projectile body having fore and aft ends, an explosive charge disposed in the projectile body, and a projectile-forming or jet-forming liner disposed in the projectile body. The liner includes an aft surface contiguous with the explosive charge and a fore surface that defines a void. A liner restraint abuts a fore end of the liner and restrains movement of the liner. A portion of the liner restraint comprises a material having a heat deflection temperature less than the critical temperature of the explosive charge in the munition.
