Abstract
An explosive breaching device is made from a surplus bomblet. The bomblet includes a shaped-charge liner, a steel fragmentation case with an open end, explosive material disposed between the shaped-charge liner and the steel fragmentation case, and a fuze. The fuze of the bomblet is removed and a shock-attenuating case is fixed adjacent to and coaxial with the steel fragmentation case. The shock-attenuating case may be made of a material having a speed of sound that differs from the speed of sound in the steel fragmentation case. A mild steel housing is fixed around the shock-attenuating case. A retaining sleeve may be fixed to the mild steel housing. The explosive breaching device may be mounted in an aiming device to direct the shaped-charge jet in a desired direction.
