Abstract:
1. A selectable fragment size warhead for a projectile comprising: a pair of circular shaped base elements in between which are mounted: an axially concentric hollow shell casing surrounding said outer sleeve; said inner sleeve having a first pattern of relatively small holes, and a second pattern of relatively larger holes, there through; said outer sleeve having a third pattern of holes, of diameter equal to the holes in said second pattern, there through; whereby said outer sleeve and said inner sleeve may be rotated axially with respect to one another to selectively expose either said first pattern holes or said second pattern holes, to show through the holes of said third pattern on said outer sleeve; whereby said shell casing is exploded into fragments when the main charge is detonated, the fragment size influenced by alignment of the third pattern holes with either the first pattern holes or the second pattern holes, alignment to first pattern holes leading to smaller sized fragments while alignment to second pattern holes leading to larger sized fragments.
