Abstract
The fragmentation jacket of a projectile or shell should be prefragmentized in the simplest possible manner by means of reference fracture locations provided at the inner side or interior surface of the fragmentation jacket. For this purpose, the reference fracture locations are impressed into a disk, for example, by stamping. Subsequently, the thus formed disk is shaped by deep drawing to form a fragmentation jacket such that the reference fracture locations formed by grooves are located at the inner side or interior surface of a cup-shaped fragmentation jacket. This cup-shaped fragmentation jacket is filled with an explosive charge which is detonated by a base fuze or by a tip or point fuze.
