Abstract : An explosive charge for underwater use comprising a shaped charge behind a main charge. The shaped charge is detonated, propelling a jet from the liner of the shaped charge through a tube extending through the main charge. When the jet passes through the water, it creates a cavity behind it. The main charge is detonated after a delay sufficient to allow the explosive energy to enter the cavity before the cavity begins to collapse.
