Abstract
Abstract A warhead for a guided missile or the like is provided with selectively operable multiple initiation devices, encased in a contoured fragmentation casing designed to optimize the initial available explosive energy to effect the most efficient transfer of energy into high velocity fragments. A shift of the fragment beam spray can be obtained by selective initiation of either end of the warhead or simultaneous initiation at both ends.
