Claims

• What is claimed as new and desired to be secured by Letters Patent of the United States is: 1. A frangible payload-dispensing projectile that is to be launched from a launcher towards a target, comprising: a spherical capsule defining a closed interior and defining an exterior surface having a plurality of dimples formed therein with areas of spacing provided between said plurality of dimples wherein, at a base of each of said plurality of dimples, thickness of said spherical capsule is insufficient to withstand impact forces delivered thereto upon contact with said target and wherein, at said spacing, thickness of said spherical capsule is greater than said thickness at each said base and sufficient to withstand launch forces delivered thereto by said launcher, said capsule further having drag-enhancing channels cut into said capsule at said exterior surface in said areas of spacing, wherein each of said channels terminates at either end thereof at one of said plurality of dimples; a second plurality of dimples formed in an interior surface of said spherical capsule, each of said second plurality of dimples aligned with one of said areas of spacing between said plurality of dimples formed on said exterior surface; and a dispersible fill material contained within said closed interior. 2. A projectile as in claim 1 wherein each of said plurality of dimples is part spherical. 3. A projectile as in claim 1 wherein each of said plurality of dimples is identical. 4. A projectile as in claim 1 wherein said spherical capsule is constructed from a synthetic organic compound. 5. A projectile as in claim 1 wherein said spherical capsule is constructed from a hydrophilic colloidal material. 6. A projectile as in claim 1 wherein said dispersible fill material is non-lethal. 7. A projectile as in claim 1 wherein said dispersible fill material is micro-encapsulated. 8. A projectile as in claim 1 wherein said dispersible fill material includes a high specific gravity material selected from the group consisting of lead, tungsten and steel. 9. A projectile as in claim 1 wherein said plurality of dimples are uniformly distributed about said exterior surface. 10. A projectile as in claim 1 wherein each of said second plurality of dimples is part spherical. 11. A projectile as in claim 1 wherein said second plurality of dimples are uniformly distributed about said interior surface. 12. A frangible payload-dispensing projectile that is to be launched from a launcher towards a target, comprising: a spherical capsule defining a closed interior and defining an exterior surface having a plurality of identical dimples formed therein and uniformly distributed thereabout with areas of spacing provided between said plurality of identical dimples wherein, upon impact with said target, localized fractures form in said spherical capsule at each base of said plurality of identical dimples, said capsule further having drag-enhancing channels cut into said capsule at said exterior surface in said areas of spacing, wherein each of said channels terminates at either end thereof at one of said plurality of identical dimples; a second plurality of identical dimples formed in an interior surface of said spherical capsule, each of said second plurality of identical dimples aligned with one of said areas of spacing between said plurality of identical dimples formed on said exterior surface; and a dispersible fill material contained within said closed interior. 13. A projectile as in claim 12 wherein each of said plurality of identical dimples is part spherical. 14. A projectile as in claim 12 wherein said spherical capsule is constructed from a synthetic organic compound. 15. A projectile as in claim 12 wherein said spherical capsule is constructed from a hydrophilic colloidal material. 16. A projectile as in claim 12 wherein said dispersible fill material is non-lethal. 17. A projectile as in claim 12 wherein said dispersible fill material is micro-encapsulated. 18. A projectile as in claim 12 wherein said dispersible fill material includes a high specific gravity material selected from the group consisting of lead, tungsten and steel. 19. A projectile as in claim 12 wherein said second plurality of identical dimples are arranged in a repeating triangular pattern and said plurality of identical dimples formed on said exterior surface are arranged in a repeating hexagonal pattern, wherein each said hexagonal pattern is concentric with one of said second plurality of identical dimples. 20. A projectile as in claim 12 wherein each of said second plurality of identical dimples is part spherical. 21. A projectile as in claim 12 wherein said second plurality of identical dimples are uniformly distributed about said interior surface.
