Abstract:
1. A missile nose payload portion comprising: a casing that includes a target penetration nose cone; and an explosive charge within the casing; wherein the casing also includes a frangible nose cover that covers a cutout in the target penetration nose cone; wherein the cutout in the target penetration nose cone is a central opening in a forward tip of the nose cone, such that a longitudinal axis of the missile passes through the cutout, and does not pass through the nose cone; wherein the frangible nose cover is weaker than the target penetration nose cone; wherein the target penetration nose cone and the frangible nose cover together have a single continuous smooth outer surface shape, without any substantial shape discontinuity at a boundary between the target penetration nose cone and the frangible nose cover; and wherein the target penetration nose cone extends forward of the explosive charge and tapered inward to the cutout such that a cutout diameter of the cutout is less than about 75% of an overall diameter of the missile.
