Abstract:

A warhead has a pair of shells, each having an annular rim at one end and an opening at the other end. The rims abut one another and are fastened together to define a chamber fitted with explosive having a bore aligned with the openings. The explosive has sensitivity to detonation that requires axial detonation in the bore by a detonating cord to initiate explosion thereby preventing detonation by lesser stimuli. A tube extends through the openings and bore and is sized to receive the detonating cord. Opposite ends of the tube are crimped to hold the shells together. A line charge provided with a plurality of such warheads has significant pressure, shock, fragmentation energy, wire cutting ability and mine neutralization capacity as compared to contemporary devices. These improved capabilities are directly attributed to the explosive type and density of this design. In addition, the materials selected for fabrication have the appropriate toughness hardness, and thickness to generate these capabilities upon detonation of the explosive. When tested against anti-personnel mines and wire obstacles, this lightweight design was efficient and effective. Furthermore, as an added feature, this warhead was found to comply with all insensitive munitions requirements.
