ABSTRACT:
In the use of a shaped explosive charge device underwater, the stand-off and cavity chamber are filled with compressed gas which is fed into the chamber to expel water through one or more apertures communicating with the surrounding water. Conveniently the apertures remain open and the compressed gas is entrapped and maintained within the device by the ambient hydrostatic pressure.
