Abstract

A fragmentation projectile having at least two adjacent casings including an inner casing having an inner surface and an outer surface, and at least one outer casing substantially surrounding the outer surface of the inner casing. An explosive charge is disposed within the inner casing, and an incendiary mass is disposed on the inner surface of the inner casing and facing the explosive. Structured zones are defined on the inner casing and include regions of lesser wall thickness than the portions of the inner casing surrounding the regions to cause a shock wave generated when the explosive charge is detonated to be transferred locally into the at least one outer casing to produce fragments of a predetermined size and shape.
