Abstract : A metal cup encloses layers of armoring material to enhance the penetration resistance of a guided missile warhead to mechanical countermeasures. A layer of ceramic material is inserted in the cup followed by the insertion of at least one pair of layers consisting of a layer of metal backed by a layer of polymethylmethacrylate. The metal cup is attached to the forward end of a missile warhead section and the exterior of the cup is conformal with respect to the exterior of the warhead section. The layered materials act to blunt or break incoming projectiles, absorb their kinetic energy, and prevent their penetration into the interior of the warhead. Patents. (AW)
