Abstract
Ammunition, such as a warhead with an explosive charge comprises a casing which is provided with a material construction of a nature providing at least controlled formation of fragments of a certain preferred mass, coverings for formation of explosion formed projectiles of a certain preferred mass, or preformed fragments of a certain preferred mass. The explosive charge is located within the casing and there are means for selective munition conversion alternatively to control formation of fragments or to natural fragmentation. For this purpose one or more recesses are provided in the explosive charge adjacent the casing as a means for munition conversion to the formation of explosion formed projectiles or unshattered preformed fragments. The filling of inert material is provided in at least a portion of the recess and it comprises a liquid inert material or a plastic inert material or a liquid explosive or plastic explosive.
