Abstract
A preformed composite fragmentation warhead includes preformed composite fragments tightly packed around a casing that includes an explosive. The preformed composite fragments include an inner core encapsulated with an outer jacket. The inner core and outer jacket are formed from different metal materials with the density of the material for the outer jacket being lower than the density of the material for the inner core. Upon contact with a 'soft' target, the outer jacket deforms and widens to increase the diameter of the preformed composite fragment. Upon contact with a “hard” target, the outer jacket erodes or shatters allowing the inner core to penetrate the hard target. The outer jacket also serves to reduce spalling upon detonation of the warhead explosive. The outer jacket fully encapsulates the inner core to ensure that the outer jacket impacts the target.
