Abstract
A fragmentation warhead includes a cylindrical body, and an explosive charge disposed within the innermost part of the warhead body. Upon detonation of the explosive charge, the warhead body is ultimately caused to shear and break into fragments with controlled sizes, shapes. This invention enables target-adaptable fragmentation output based selectively controlling the size of preformed fragments ejected. Preformed tungsten alloy fragments of a first 'small' size 'A' are sintered to be joined into a plurality of larger size fragments “B”, using a tungsten alloy matrix. The B fragments are then joined into a desired shell shape and thickness and sintered into a fragmenting shell body using a different tungsten alloy matrix with bonds of melting point considerably lower than amongst the A fragment bonds.
