1. Fragmentation warhead, comprising:
- an axially extending cylindrical jacket having an outer surface and an inner surface;
a fragmentation layer encircling and in contact with the outer surface of said jacket;
a main explosive charge located within the jacket;
a plurality of separate deformation charges located around and spaced outwardly from said fragmentation layer, said deformation charges extending in the axial direction of said jacket and arranged to inwardly deform the jacket and fragmentation layer along a side of the warhead facing a target before igniting the main explosive charge located within the jacket;
means for locating the deformation charges around and spaced outwardly from the fragmentation layer;
means for individually controlling and igniting a group of said deformation charges;
an axially extending central tube located within and spaced inwardly from said cylindrical jacket and forming therebetween an annular space, wherein said main explosive charge is located within said annular space between said central tube and cylindrical jacket;
wherein said fragmentation layer has;
an outer surface;
a damping layer extending radially outwardly from the outer surface of said fragmentation layer and forming an axially extending outer surface of said warhead; and
axially and radially inwardly extending recesses located in the outer surface of said damping layer, said recesses spaced circumferentially apart and containing said deformation charges.

Abstract
An axially extending fragmentation warhead having a plurality of separate axially extending deformation charges in its radially outer surface. The deformation charges are located in a damping layer enclosing a fragmentation layer covering a cylindrical jacket enclosing a main explosive charge. The deformation charges facing a target can be individually ignited to inwardly deform the cylindrical jacket and the fragmentation layer prior to igniting the main explosive charge for selectively directing the fragmentation layer at the target. The deformation charges can be ignited individually or in selected groups to increase the effectiveness of the fragments directed at the target.
