Target discriminating bomblet

A target discriminating bomblet for distinguishing between hard and soft targets, comprising:

• a warhead, having
• an ogive-shaped fragmentation case;
• a conical shaped charge liner mounted within said case;
• an explosive load located in said case between said case and said liner;
• and
• a zirconium cup circumferentially attached to said case;
• and a fuse, having
• a stab detonator;
• an explosive transfer line, one end of which is adjacent to said detonator and the other end of which is attached to a booster charge located within said warhead;
• a first firing pin located adjacent to said detonator when the bomblet is armed;
• a first cylindrical body held closely within a second cylindrical body forming a part of a housing for said fuze and relative axial movement between said two cylindrical bodies being prevented by at least one shear rivet passing through walls of said bodies;
• a stab primer;
• a second firing pin having a pointed and a non-pointed end, said pin located adjacent to said primer when the bomblet is armed;
• expulsion means for propelling the bomblet warhead into the air after the bomblet has impacted a soft target;
• a first pyrotechnic delay connecting said primer with said expulsion means for igniting said expulsion means;
• a second pyrotechnic delay connecting said primer with said detonator;
• said second delay being sufficiently longer than said first delay so that the bomblet warhead is propelled into the air prior to detonation of said warhead;
• said housing defining a ball mass chamber having a centering receptacle which forms a first end of said chamber opposite said stab primer, and said primer forming a second end of said chamber;
• a metal ball-shaped inertial mass poised to inertially plunge said second firing pin into said primer upon a sudden deceleration of the bomblet, said ball mass being contained within said chamber;
• a hemispherical cup attached to said non-pointed end of said second firing pin and holding said ball-shaped mass within said cup;
• and
• resilient means for urging said cup and said second firing pin away from said primer and toward said centering receptacle;
• so arranged and constructed that the bomblet striking a soft target will fail to activate said first firing pin and will activate said second firing pin to initiate said expulsion means for propelling the bomblet warhead into the air where said warhead is detonated, and so that the bomblet exhibits pyrophoric properties upon detonation.
