Patent ID: 7971535

Claim:
A controlled fragmentation warhead, comprising: a case having and inner surface and an opening, said case formed of a material that is pulverized upon detonation; an explosive in said case that is in conformal contact with the inner surface of the case eliminating metal fragments thrown radially from the warhead; a fragmentation assembly in said opening, said fragmentation having an aft surface, means for detonating said explosive to produce a pressure wave across the aft surface of the fragmentation assembly that expels metal fragments from the fragmentation assembly, and a pattern shaper between said explosive and said fragmentation assembly, said pattern shaper having a fore surface in conformal contact across the entire aft surface of the fragmentation assembly to shape the front of the pressure wave as it propagates through the pattern shaper and across the aft surface of the fragmentation assembly to shape a pattern density of the expelled metal fragments.
