ABSTRACT:
A shaped charge explosive warhead assembly is composed of a one piece shaped charge liner including an explosive initiation charge, and a main explosive charge which surrounds the shaped charge liner. The one piece shaped charge liner includes a forward thin wall section and an integral tail end section having a common longitudinal axis of symmetry. The forward thin wall section includes wall portions having a trumpet or other selected shape, and the tail end section includes a plurality of symmetrically located spoke-like apertures extending radially from the longitudinal axis of symmetry and further includes a central bore hole extending from an end surface of the tail end section and in communication with the spoke-like apertures. The spoke-like apertures and bore hole of the tail end section are filled with the explosive initiation charge. A detonator is coupled to the explosive initiation charge within the bore hole.
