Abstract
A shaped charge device for a projectile has a nested structure which provs a relatively long lethal jet. The device employs a body of explosive material having a hollow formed therein. A sheath formed of ductile material is mounted within that hollow. Coaxially mounted within the sheath is an elongated casing. The casing which is formed of ductile material is spaced from the sheath. A layer of material is interposed between the sheath and casing. Upon detonation of the body of explosive material, the casing violently collapses to form a lethal jet.
