Abstract: A method for producing a warhead with directed blasting action involves the step of making an outer casing and arranging therein a charge with a cavity situated at the front end of the charge. An insert whose shape corresponds to the shape of the cavity is arranged on the surface of the charge. The method furthermore involves the step of depositing a material on the insert in an additive manufacturing process. A warhead manufactured according to the method includes an outer casing, a charge with a cavity situated at the front end of the charge, and an insert. A material is deposited on the insert.

Abstract: A procedure for producing a warhead with controlled fragmentation includes manufacturing an inner shell and filling it with an explosive substance. The procedure further includes providing a net around the outer surface of the inner shell as well as depositing a material on and around the net. A warhead is produced by the procedure and includes an inner shell. A material applied to the warhead comprises weak points for guided fragmentation of the deposited material upon detonation of the warhead.

Abstract: A method is provided for producing a warhead component including an inner shell. The method includes arranging a first casing of a thermoplastic to enclose the inner shell, arranging pre-formed projectiles between the first casing of thermoplastic and the inner shell, and heat-treating the first casing so that the first casing shrinks and fixes the pre-formed projectiles to the inner shell. A warhead, a projectile, and a bomb are also provided.

Abstract: A method is provided for producing a component for a warhead, wherein the method involves the steps: i.) an inner shell is arranged on a tool, ii.) preshaped projectiles are arranged on the inner shell, iii.) powder is arranged to enclose the preshaped projectiles, iv.) the powder is pressed such that the powder, the preshaped projectiles, and the inner shell are joined together, v.) the tool is removed from the component formed from the powder, the preshaped projectiles, and the inner shell. A warhead and a projectile are also provided.
