A missile, such as a cruise missile, has a nose payload portion having a frangible nose cover and a relatively hard target penetration nose cone. The nose cone may have a liquid fuel tank within, and a chemical energy explosive charge, such as a shaped charge, aft of the liquid fuel tank. The target penetration nose cone enables perforation of certain types of targets prior to detonation of the chemical energy explosive and the liquid fuel. The frangible nose cover is configured to be easily perforated or otherwise removed by the explosive force of the chemical energy explosive charge when the missile system is utilized for the attack of hard targets. The nose payload portion may have a fragmentation case, with one or more features designed to enhance fragmentation during detonation of the explosive and/or the liquid fuel.

What is claimed is: 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. 2. The nose payload portion of claim 1, wherein the target penetration nose cone includes a material selected from a group consisting of one or more of a metal, an alloy and a high strength composite. 3. The nose payload portion of claim 2, wherein the target penetration nose cone has a thickness greater than about 6.4 mm (0.25 inches). 4. The nose payload portion of claim 1, wherein a cutout diameter of the cutout is greater than about 25% of the overall diameter of the missile. 5. The nose payload portion of claim 1, wherein the frangible nose cover has a thickness of less than about 6.4 mm (0.26 inches). 6. The nose payload portion of claim 1, wherein the frangible nose cover is thinner than the target penetration nose cone. 7. The nose payload portion of claim 1, wherein the frangible nose cover includes a material of lower density than steel. 8. The nose payload portion of claim 7, wherein the explosive charge includes a shaped charge; wherein the frangible nose cover overlies a front surface of at least a center portion of the shaped charge; and wherein the frangible nose cover is configured to be perforated by explosive force of the shaped charge. 9. The nose payload portion of claim 1, wherein the explosive charge includes a shaped charge. 10. The nose payload portion of claim 1, wherein the explosive charge includes a platter charge, an explosively formed penetrator, a flyer plate, or another explosive device or explosive filling. 11. The nose payload portion of claim 1, wherein the casing includes a fragmentation case. 12. The nose payload portion of claim 11, wherein the fragmentation case is located aft of the target penetration nose cone. 13. The nose payload portion of claim 11, wherein the fragmentation case includes a plurality of fragments, located in a recess in the casing or on the surface of the casing. 14. The nose payload portion of claim 13, wherein the fragments are made of one or more metal alloys. 15. The nose payload portion of claim 13, wherein the fragments are embedded in a high strength adhesive within the recess or on the surface of the casing. 16. The nose payload portion of claim 11, wherein the fragmentation case is scored on either the inside or outside surface of the casing to produce enhanced fragmentation effects. 17. The nose payload portion of claim 11, wherein the fragmentation includes a fragmentation liner within the fragmentation case to produce enhanced fragmentation effects. 18. The nose payload portion of claim 1, wherein substantially all of the frangible nose cover is longitudinally forward of substantially all of the target penetration nose cone. 19. The nose payload portion of claim 1, wherein the explosive charge is within a cylindrical aft part of the casing; and wherein the explosive charge extends substantially fully across the cylindrical aft part of the casing. 20. The nose payload portion of claim 1, as part of a powered cruise missile. 21. A missile nose payload portion comprising: a casing that includes a target penetration nose cone; an explosive charge within the casing; and a nose cone fuel tank within the casing, forward of the explosive charge; wherein the casing also includes: a frangible nose cover, substantially all of which is longitudinally forward of substantially all of the target penetration nose cone; and a fragmentation case located aft of the target penetration nose cone; wherein the frangible nose cover is of lower density than target penetration nose cone material of the target penetration nose cone; wherein the nose cone fuel tank contains a liquid fuel; wherein the target penetration nose cone has a diameter at least as large as a diameter of the explosive charge; wherein the frangible nose cover 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; and wherein the target penetration nose cone extends over substantially all of a front surface of the missile nose payload portion.
