A deliverable weapon, such as a missile, an artillery round, an aerial bomb, or a mortar round, having an explosive warhead, utilizes concentric annular sleeves that upon detonation provide placement of smaller fragments of an inner annular sleeve interstitially with respect to larger fragments of an outer annular sleeve in an expanding fragmentation curtain that contains expanding gases to increase the pressure of the explosion and the kinetic energy transferred to the fragments. In embodiments, the sleeves are comprised of ordered layers of spherical metal fragments encased in binder material and an outer casing.

A method for preparing a composite projectile body with preformed fragments precisely embedded within the walls of the projectile body. The process utilizes a combination of additive manufacturing and advanced powder metallurgy fabrication techniques. Specifically a skeletal structure or prefabricated cage body is filled with preformed fragments. The cage structure may be situated on a mandrel or tool inside a container. The container is filled with metal powder, degassed under vacuum, and sealed. The canister is then subjected to heat and pressure to consolidate the powder to full density. The canister is then removed and the compacted billet product is further machined to obtain a desired projectile body.

A fragmentation warhead for a missile includes a warhead casing, an active charge arranged within the warhead casing, and a fragmentation filling arranged within the warhead casing in front of the active charge of the fragmentation warhead in an effective direction of the fragmentation warhead. When the active charge is ignited, fragments are hurled out of the fragmentation filling in the effective direction within a first outlet opening angle. The fragmentation warhead includes a fragmentation damping charge, which is arranged within the warhead casing laterally to the effective direction on the fragmentation filling, to exert a lateral damping pressure on the fragmentation filling upon ignition. The fragmentation warhead includes a fragmentation damping filling, which is arranged within the warhead casing laterally to the effective direction on the fragmentation filling such that the metal powder is released laterally from the fragmentation filling when the active charge is ignited.
