Abstract
A munition that is adapted to enhance fragmentation effects upon detonation includes preformed fragments between a casing and a shell. The overall mass of the preformed fragments is greater than the overall combined mass of the casing and the shell for enhancing the degree of controlled fragmentation compared to uncontrolled fragmentation. By enhancing the dispersal of controlled fragmentation, the overall fragmentation area coverage and fragmentation pattern density may also be enhanced while limiting travel of the fragmentation beyond the target area for reducing collateral damage. The preformed fragments may fill a continuous volume between the casing and the shell to effectively utilize the munition volume and to maximize the amount of preformed fragments contained within the shell. The preformed fragments may be free flowing pellets that are poured into the volume between the casing and the shell for enhancing distribution of the fragments and for improving assembly of the munition.
