Shock sensing dual mode warhead

A shock sensing dual mode warhead for use against both soft and hard targets and capable of sensing which type of target has been struck comprising:

• a hollow casing formed of a strong ductile material;
• a base closure for closing the rearward end of said casing;
• a structurally-stiff explosive charge filling the interior of said casing;
• a booster mounted on said base closure and disposed within said explosive charge for detonating said explosive;
• and
• a shock-sensing fuze assembly mounted on said booster for initiating said booster upon impact with a target, said fuze assembly comprising:
• a low g inertial firing train responsive to low impact deceleration for initiating said booster upon impact with a soft target, said low g firing train including a time delay element to permit substantial penetration of the target before detonation of said explosive charge;
• and
• a high g firing train responsive to dynamic pressure within said explosive charge caused by high impact deceleration for initiating said booster upon impact with a hard target, the ductility of said casing allowing said casing to mushroom without fragmenting upon impact with a hard target thereby disposing more of said explosive charge closer to the surface of said target prior to detonation of said explosive charge whereby the blast effectiveness is increased.
