A tacital base for a guided projectile includes a base structure, and an adaptor structure for securing the base structure to a forward section of the projectile. The base further includes a plurality of fin slots. A plurality of deployable fins are pivotally mounted to the base structure and supported for movement between a stowed position and a deployed position.

1. A base for a projectile, comprising:a base structure having a forward bulkhead in a hemispherical dome shape, the base structure including an aft end having a plurality of cavities formed therein, the cavities separated by a set of corresponding radial rib structures extending outwardly to a base
1. A base for a projectile, comprising:a base structure having a forward bulkhead in a hemispherical dome shape, the base structure including an aft end having a plurality of cavities formed therein, the cavities separated by a set of corresponding radial rib structures extending outwardly to a base outer surface, with at least one strut member disposed in each cavity and extending between corresponding opposed rib structures;a plurality of fin slots defined in the base structure; anda plurality of deployable fins mounted to the base structure and supported within the fin slots for movement between a stowed position and a deployed position. 2. The base of claim 1, wherein each of said at least one strut member has a generally circular cross-sectional configuration. 3. The base of claim 1, wherein said fin slots are defined in respective ones of said rib structures. 4. The base of claim 1, wherein the base structure is a unitary, one-piece structure. 5. The base of claim 1, wherein the base structure is fabricated of titanium or a titanium alloy. 6. The base of claim 1, wherein each of the fins are pivotally mounted in said slots for pivoting movement about a pivot point from said stowed position to said deployed position. 7. A base for a projectile, comprising:a base structure having a forward bulkhead structure, the base structure including an aft end having a plurality of cavities formed therein, the cavities separated by a set of corresponding radial rib structures extending outwardly to a base outer surface, with at least one strut member disposed in each cavity and extending between corresponding opposed rib structures;a plurality of fin slots defined in the base structure; anda plurality of deployable fins mounted to the base structure and supported within the fin slots for movement between a stowed position and a deployed position. 8. The base of claim 7, wherein each of said at least one strut member has a generally circular cross-sectional configuration. 9. The base of claim 7, wherein said fin slots are defined in respective ones of said rib structures. 10. The base of claim 7, wherein the base structure is a unitary, one-piece structure. 11. The base of claim 7, wherein the base structure is fabricated of titanium or a titanium alloy. 12. A base for a projectile, comprising:a base structure having a forward bulkhead structure, the base structure including an aft end having a plurality of cavities formed therein, the cavities separated by a set of corresponding radial rib structures extending outwardly to a base outer surface, with at least one strut member disposed in each cavity and extending between corresponding opposed rib structures;a plurality of fin slots defined in the base structure;a plurality of insert structures fitting into corresponding ones of the fin slots;a plurality of deployable fins mounted to the base structure and supported within the insert structures for movement between a stowed position and a deployed position. 13. The base of claim 12, wherein each of said at least one strut member has a generally circular cross-sectional configuration. 14. The base of claim 12 herein said fin slots are defined in respective ones of said rib structures. 15. The base of claim 12 wherein the base structure is a unitary, one-piece structure. 16. The base of claim 12 wherein the base structure is fabricated of titanium or a titanium alloy. 17. The base of claim 12, wherein forward bulkhead forms a hemispherical dome shape. 18. A base for a projectile, comprising:a base structure having a forward bulkhead structure, the base structure including an aft end having a plurality of cavities formed therein, the cavities separated by a set of corresponding radial rib structures extending outwardly to a base outer surface;a plurality of fin slots defined in respective ones of said rib structures in the base structure; anda plurality of deployable fins mounted to the base structure and supported within the fin slots fo r movement between a stowed position and a deployed position; andwherein during firing of the projectile from a gun barrel, gasses at high pressure generated from a propellant enter said cavities, and said radial rib structures and said bulkhead structure have sufficient strength to prevent deflection of said radial rib structures into contact with said fins. 19. The base of claim 18 herein said fin slots are defined in respective ones of said rib structures. 20. The base of claim 18 wherein the base structure is a unitary, one-piece structure. 21. The base of claim 18 wherein the base structure is fabricated of high strength titanium or high strength steel. 22. The base of claim 18, wherein forward bulkhead structure forms a hemispherical dome shape.
