An explosive fragmentation munition having a longitudinal axis which includes a cylindrical shell portion having a thickness and an interior; a rounded shell portion having a thickness and an interior, the rounded shell portion being disposed at a front end of the cylindrical shell portion; an explosive disposed in the interiors of the cylindrical shell portion and the rounded shell portion; wherein the thickness of the rounded shell portion equals the thickness of the cylindrical shell portion where the rounded shell portion joins the cylindrical shell portion, and wherein the thickness of the rounded shell portion increases in a forward direction along the longitudinal axis.

What is claimed is: 1. An explosive fragmentation munition having a longitudinal axis, comprising: a single-layered, generally cylindrical shell portion having a thickness; an exposed rounded nose having a thickness, the nose being disposed at a front end of the cylindrical shell portion; an explosive disposed inside the cylindrical shell portion and the nose; wherein the nose includes a pusher liner that is made of a similar material as the cylindrical shell portion, and a multi-layered anterior liner that is disposed on an outer surface of the pusher liner; wherein the multi-layered anterior liner is made of a high-density material that is different from the material of the cylindrical shell portion and that adds mass to the nose, so that the pusher liner transfers momentum to the anterior liner, which, in turn, projects fragments in a forward direction; and wherein the anterior liner includes a plurality of holes that cause the munition to fragment into a plurality of small fragments. 2. The munition of claim 1 wherein the anterior liner contains preformed fragments disposed therein. 3. The munition of claim 1 the anterior liner includes scoring on an outer surface thereof. 4. The munition of claim 1 wherein the material of the pusher liner is steel. 5. The munition of claim 1 wherein the anterior liner is made at least in part of tungsten alloy and contains preformed fragments embedded in an alloy matrix. 6. The munition of claim 1 wherein the anterior liner is multi-layered and comprises at least a first layer made of a material that is selected from the group consisting of tungsten, tantalum, hafnium, lead, and depleted uranium alloys. 7. The munition of claim 6 wherein the multi-layered anterior liner comprises a second layer that is made of a material selected from the group consisting of tungsten, tantalum, hafnium, lead, and depleted uranium alloys. 8. The munition of claim 7 wherein the anterior liner comprises a third layer that is stacked on the second layer. 9. The munition of claim 8 wherein the third layer is made of a material that is selected from the group consisting of tungsten, tantalum, hafnium, lead, and depleted uranium alloys. 10. The munition of claim 9 wherein the anterior liner contains fragments disposed therein, intermediate the first layer and the second layer. 11. The munition of claim 10 wherein said fragments may be shaped as spheres or cubes. 12. The munition of claim 10 wherein the material density of the embedded fragments is different from the anterior liner, to aid in separation of the embedded fragments upon detonation. 13. The munition of claim 9 wherein the anterior liner contains fragments disposed therein, intermediate the second layer and the third layer. 14. The munition of claim 1, wherein the cylindrical shell portion has a generally uniform thickness. 15. The munition of claim 1 wherein small holes are placed in the exterior body of the munition, to aid in breakup of the warhead when it fragments. 16. The munition of claim 15 wherein small holes are placed in the front cap area of the munition, to aid in breakup of the warhead when it fragments. 17. The munition of claim 15 wherein the small holes are star-shaped cross-sectionally. 18. The munition of claim 1 wherein the shape of the warhead anterior layer is non-conical, and is patterned from a third order parametric polynomial curve. 19. The munition of claim 1 wherein the warhead contains no plastic material.
