A shaped charge liner is made by forming a pair of hollow conical sub-liners, without any uncontrolled residual tangential shear stress (e. g. by a deep drawing method) so that they mate together to form a single conical liner. One sub-liner is inserted in the other and then one pair of subliner ends are locked together. Thereafter, the sub-liners are counter-rotated about their attachment point and locked together at their other pair of ends to retain the counter-rotation. This counter rotation generates opposite residual tangential shear stresses in the two sub-liners which may or may not be equal to each other.

Warhead fragment size can be selectively controlled by: (1) internally or externally grooving a warhead casing; (2) providing an internal casing liner or explosive charge with a predetermined cutting groove pattern confronting the grooves in the casing; (3) positioning the liner or explosive charge groove pattern relative to the casing groove pattern so that warhead fragments of one size will be produced if the grooves in the liner or explosive charge are rendered ineffective for cutting the warhead and so that fragments of another size will be produced if the grooves in the linear or explosive charge are not rendered ineffective and therefore are utilized to cut the casing; (4) providing apparatus in the warhead for delivering a fluid such as water to the grooves in the linear or explosive charge to selectively inhibit the cutting action of those grooves to provide desired warhead fragment size(s). Fluid delivery can be effected before warhead flight or it can be effected during flight by remote control to provide warhead fragment sizes adjusted to the "hardness" or "softness" of a designated target.
