Abstract
A cartridge assembly for breaching a door including a cartridge case, a cartridge body, and a fuse. The cartridge case contains a first propellant and a primer. The cartridge body has a rearward end in locking engagement with a forward end of the cartridge case, a channel located in the cartridge body contains an extrudable explosive, a piston in slidable engagement in the channel is in a forward end of said channel, the piston being forward of the extrudable explosive contained in the channel, whereby rearward movement of the piston forces extrudable explosive rearwardly and radially outwardly through extrusion ports into a cavity inside of the cartridge body where a bladder is stowed. The piston has a rearwardly projecting detonator pin which upon movement to a rearward most position engages a rearward escapement and detonator which in turn initiates detonation of explosive in the bladder. A fuse is attached to a forward end of the cartridge body. A proximity fuse or contact fuse may be used.
