Abstract
A fragmentation munition has a fragmentation canister containing preformed fragments, and an explosive cartridge that fits into a central hole in the fragmentation canister. The explosive cartridge includes an outer shell, and an explosive within the outer shell. The munition may be configured to precisely deliver fragments to a relatively small area, such as an area that is a few meters in radius. Toward that end the explosive may be configured primarily to rupture the housing and secondarily to spread fragments over a limited area. The main kinetic energy of the fragments is from the acceleration they gain as part of the munition falls from a launcher, such as a carrier aircraft. The dispersed fragments may have a similar downward velocity after controlled dispersal by the explosive, allowing them considerable kinetic energy (considerable penetrating power), but with a precisely controlled dispersal area.
