  • Patent number: 7930978
    Abstract: A forward firing fragmentation warhead is constructed with casing materials that are pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality may be improved by forming the fragmentation layer and explosive with dome-shapes that approximately match the shape of the advancing pressure wave. This increases fragment velocity and improves the uniformity of the fragment distribution over the forward-firing pattern. A variable-thickness pattern shaper may be placed between the fragmentation layer and explosive to provide additional shaping of the forward-firing pattern. Warhead weight and cost can be reduced by eliminating explosive at the aft end of the warhead that does not contribute to the total energy imparted to the fragments.
