  • EXPLOSIVELY FORMED PENETRATOR (EFP) AND FRAGMENTING WARHEAD
    Publication number: 20030177935
    Abstract: A warhead casing defines a geometry that is a portion of a ring having an outer radial wall and an inner radial wall spaced radially apart from one another. The outer radial wall and inner radial wall are joined radially by side walls, while the casing is enclosed at either axial end thereof by end walls. An explosive material fills the casing. At least one initiator is positioned in the explosive material along a radial plane that bisects the portion of the ring. Detonation of the explosive material causes the inner radial wall to form an EFP while the outer radial wall fragments.
