Abstract: An apparatus for detonating a munition having a munition casing. The apparatus includes a pyramidal shaped housing with an interior to receive explosive material and a stepped structure defining a plurality of tier sections. The housing includes a bottom portion and an interior space to receive an energetic device. A force-reactive component secured to the bottom portion of the housing confronts the munition casing and includes a force-receiving portion exposed to the housing interior. The force-reactive component impacts the munition casing when a force is exerted upon the force-receiving portion. After the apparatus is positioned on the casing, explosive material is packed into the housing interior and an energetic device disposed within the additional space, the energetic device is detonated and the force-reactive component impacts the munition casing where shock waves permeate the munition casing and detonate the munition.
