ABSTRACT:
The present invention provides a high-lethality low collateral damage fragmentation warhead. The case is formed of a material that is 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 is improved by placing a pattern shaper between the fragment assembly and the explosive. The explosive and pattern shaper have a conformal non-planar interface that shapes the pressure wavefront as it propagates there through to expel metal fragments from the fragmentation assembly with a desired pattern density over a prescribed solid angle.
