ABSTRACT:
A target discriminating antipersonnel/antimaterial cluster weapon capable distinguishing between hard and soft targets. Upon striking a hard target such as armor or concrete, shear rivets are defeated causing a striker to plunge a firing pin into a stab detonator which through an explosive transfer train causes immediate detonation of the bomblet. Upon hitting a soft target such as sandy soil, the shear rivets will not be sheared, however, an inertia firing weight plunges a firing pin assembly into a stab primer which leads to a propellant charge causing the bomblet to pop back up into the air. The bomblet then is detonated through a pyrotechnic delay in the air. The bomblet is armed during its descent via a flutter plate giving oscillatory motion which is transferred into rotary motion. The rotary motion is employed to align the primer and detonator with the firing pins.
