Abstract

A multi-mode fuze (20) for a munition (10, 40) has at least one sensor (16, 22, 42) that generates an electrical output (62) dependent on a rate of deceleration when the munition (10, 40) impacts a target, a logic circuit (60) electrically coupled to the at least one sensor (16, 22, 42) effective to discriminate between a soft target and a hard target dependent on the electrical output (62) and a fuze (20) that transmits a detonation signal to an initiating explosive (28) to thereby detonate the munition (10, 40). The detonation signal is transmitted at a time dependent on target discrimination. The multi-mode fuze (20) of the invention may be incorporated into an explosive projectile (10, 40) that includes an aerodynamically shaped metallic casing (12), an explosive (14) contained within the metallic casing (12) and an initiating explosive (28) contacting the explosive (14). The multi-mode fuze (20) communicates with the initiating explosive (28) to trigger detonation of the explosive (14) either on impact with a hard target or following a delay on impact with a soft target.
