ABSTRACT:
The invention, as embodied herein, comprises a variable yield warhead comprising an inner core of cylindrically-shaped, explosive material surrounded by an outer annulus of a different explosive material. The inner core explosive material has a heat of combustion comprising about 16 kcal/cc or higher and the outer annulus of explosive material has a heat of detonation comprising about 2.1 kcal/cc or higher. A warhead casing surrounds the outer annulus of material. The warhead has a dual initiation system. The first initiation system comprises a detonation cord that extends substantially through the inner core of explosive material and has an initiator at the tope side. The second initiation system comprises a booster explosive that contacts the bottom side of the outer annulus of explosive material and an initiator proximate to the booster.
