TOROIDAL WARHEAD DEVELOPMENT
Research in warhead mechanisms has primarily focused on fragmentation warheads that form large numbers of fragments to cover a large area, or anti-armor warheads that form shaped charge jets, stretchy jets, or explosively formed penetrators (EFPs). When there is a requirement for creating large openings in concrete or masonry walls, perforating holes in a target for large follow through charges, or enhancing effectiveness by pushing more metal into moderately armored targets, neither the fragmentation warhead nor the anti-armor warhead will be adequate. Fragmentation warheads have very low penetration and anti-armor warheads have a focused localized impact zone. In the last several years, the warhead design engineers at the U.S. Army Armament Research, Development and Engineering Center (ARDEC) have conducted research and development in toroidal warheads that form expanding ring penetrators. Ongoing studies show the benefits of the toroidal warheads in creating entry holes into concrete and masonry walls, creating sufficiently large holes for follow through charges, and enhancing lethality against moderately armored targets by pushing more perforated armor material into the target. Toroidal EFPs can be formed in various ways. One of which is by folding the liner onto itself as in typical EFP formation or by expanding the liner out from the center. Initial toroidal warhead prototypes were designed to continuously expand (eventually the penetrator fractures). Subsequent demonstrations showed that the size of the toroidal penetrator can be designed to expand to a specific diameter.
