The invention relates to a common carrier munition ammunition device, more particularly to common carrier payload delivery shell with a frangible ogive element. There is provided a common carrier munition comprising a tail unit, a main body which comprises a payload cavity for receiving a payload, a fuze, and located between said main body and the fuze an frangible ogive element, wherein the tail unit and main body comprise cooperatively engaging male and female threaded portions, wherein at least one of the threads is a shearable thread.

1. A frangible munition comprising: a tail unit;a main body which comprises a payload cavity for receiving a payload;a fuze;an explosive train operably connected to said fuze;a frangible ogive element located between said main body and the fuze, wherein the frangible ogive element and main body are
1. A frangible munition comprising: a tail unit;a main body which comprises a payload cavity for receiving a payload;a fuze;an explosive train operably connected to said fuze;a frangible ogive element located between said main body and the fuze, wherein the frangible ogive element and main body are retained in operable engagement by at least one frangible link, such that upon an impact, said frangible link is caused to fail;a locking ring located between the main body and said frangible ogive element, to retain said payload within the payload cavity, wherein the locking ring and main body comprise cooperatively engaging threaded portions, and wherein the frangible link of the frangible ogive element is threaded to engage the locking ring; anda further shearable portion between the main body and the tail unit having a lower shear strength than the frangible link, such that the further shearable portion between the tail unit and the main body fails prior to said frangible link being caused to fail. 2. The munition according to claim 1, wherein the frangible link is a shearable thread or at least one shear pin. 3. The munition according to claim 2, wherein the main body comprises a first threaded portion manufactured from a first material, and the frangible ogive element comprises a second threaded portion manufactured from second material, wherein the second material has a lower hardness value than the first material. 4. The munition according to claim 3, wherein the first material is selected from a steel alloy and the second material is selected from aluminium or alloy thereof. 5. The munition according to claim 1, wherein the locking ring and main body comprise cooperatively engaging threaded portions. 6. The munition according to claim 1, wherein the frangible ogive element has a forward end locatable with said fuze and an aft end locatable with said main body, wherein the internal diameter of the aft end of said frangible ogive element is substantially the same as the internal diameter of said payload cavity. 7. The munition according to claim 1, wherein the fuze is operably connected to at least one expulsion charge, wherein said charge is suspended in free space. 8. The munition according to claim 1, wherein the payload cavity has substantially parallel walls, which extend from the intersection of the tail unit to the locking ring. 9. The munition according to claim 1, wherein the payload is a modular unit. 10. The munition according to claim 9, wherein the modular unit, is reversibly loadable from the aft end of the main body. 11. The munition according to claim 2, wherein the payload is capable of being dispensed rearwardly from the main body, upon shearing the shearable thread. 12. A method of dispensing a payload from a munition according to claim 1, comprising: causing initiation of an expulsion charge, the expulsion charge operably connected to the explosive train; andcausing shearing of the shearable thread. 13. The munition according to claim 1 wherein ignition of the explosive train causes the further shearable portion between the tail unit and the main body to fail thereby allowing the payload to be dispensed rearwardly from the main body. 14. A frangible munition comprising: a main body which comprises a payload cavity for receiving a payload;a fuze;an explosive train operably connected to said fuze;a frangible ogive element located between said main body and the fuze, wherein the frangible ogive element and main body are retained in operable engagement by at least one frangible link, such that upon an impact, said frangible link is caused to fail, wherein the frangible link comprises a shearable thread;a locking ring located between the main body and said frangible ogive element, to retain said payload within the payload cavity, wherein the locking ring and main body comprise cooperatively engaging threaded portions, and wherein the frangible link of the frangible ogive element is threaded to engage the locking ring; anda further shearable portion between the main body and the tail unit having a lower shear strength than the frangible link, such that the further shearable portion between the tail unit and the main body fails prior to said frangible link being caused to fail. 15. The munition according to claim 14, wherein the main body comprises a first threaded portion manufactured from a first material, and the frangible ogive element comprises a second threaded portion manufactured from second material, wherein the second material has a lower hardness value than the first material. 16. The munition according to claim 14, wherein the locking ring and main body comprise cooperatively engaging threaded portions. 17. The munition according to claim 14, wherein the fuze is operably connected to at least one expulsion charge, wherein said charge is suspended in free space. 18. The munition according to claim 14 wherein the payload is a modular unit, and the modular unit is reversibly loadable from the aft end of the main body.
