Claims

1. A high density reactive material (HDRM) munition warhead comprising a main body with a payload cavity capable of receiving a high explosive payload, said cavity comprising,a high explosive, an HDRM material located between the high explosive and the main body,and wherein the main body comprises a plurality of preformed fragments, such that in use the HDRM material and preformed fragments are explosively driven together.

2. A munition according to claim 1, wherein the main body has a concave or convex outer surface.

3. A munition according to claim 1 or claim 2 wherein the preformed fragments are located on the outer surface of the main body.

4. A munition according to any one of the preceding claims wherein the preformed fragments are selected from a material with a higher density than the main body of the warhead.

5. A munition according to any one of the preceding claims wherein the preformed fragments have a coating of or are formed from a further HDRM material.

6. A munition according to any one of the preceding claims wherein high explosive is a non-ideal or metallised explosive.

7. A munition according to any one of the preceding claims, wherein the HDRM material, high explosive and payload cavity have parallel walls.

8. A munition according to any one of the preceding claims wherein the HDRM and / or further HDRM is selected from a composition comprising,A) at least two separate group 4 metals, present in the range of from 40 to 90%wtB) at least one oxidiser or alloying element, present in the range of from 5 to 55%wtwherein said reagents and optional pressing aids are present in substantially 100%wt.

9. A munition according to claim 8, wherein B) is at least one oxidiser, carbon or boron.

10. A munition according to claim 8 or 9, wherein the at least one oxidiser is a metal oxide.

11. A munition according to any one claims 8 to 10, wherein at least one of the group 4 metals is hafnium.

12. A munition according to claim 11, wherein the hafnium is present in the range of from 20 to 79%wt.

13. A munition according to any one claims 8 to 12, wherein there is a reagent C) a binder in the range of 1-10%wt.

14. A munition according to any one of the preceding claims wherein the HDRM is selected from a composition comprising tungsten metal, in the range of 10 to 50%wt.

15. A high density reactive material (HDRM) munition warhead comprising a main body with a payload cavity capable of receiving a high explosive payload, said cavity comprising, a high explosive, an HDRM material located between the high explosive and the main body, wherein the main body has a concave outer surface, and comprises a plurality of preformed fragments located on the outer surface of the main body, said fragments formed from a further HDRM material, said further HDRM material further comprising tungsten metal in the range of 10 to 50 wt%, such that in use the HDRM material and further HDRM preformed fragments are explosively driven together.

16. A method of defeating an unmanned aerial system(UAS) comprising the step of detonating a high explosive munition comprising an HDRM munition, as claimed in any one of the preceding claims, proximate to at least one UAS.15
