Abstract
A tandem charge for prosecution of underwater targets includes both a precursor charge (PC) and a follow through charge (FTC) oriented within and along an axis of a charge casing with the FTC positioned in front of the precursor charge. The precursor charge includes an explosive charge and a liner configured such that upon detonation of the explosive charge the liner forms an annular explosively formed penetrator (EFP) that is projected along the axis and passes around the FTC to cut a first hole in an outer surface of the target. The FTC is configured to be carried through the first hole in the outer surface of the target by the flow of water therethrough for detonation on the other side of the outer surface of the target, perhaps forming a second hole in an inner surface of the target.
