Abstract
There is disclosed a kinetic energy type projectile having an armor piercing head which is intended to penetrate multi-shell targets, and even sharply angled targets. The piercing head is provided with favorably discriminated shearing regions which are axially spaced apart by distances corresponding to the thicknesses of the shells which are to be pierced by the piercing head. The shearing regions are provided by external or internal localized transverse weakenings e.g. grooves, or heat treatments by electronic bombardment, applied to the external surface of the piercing head and/or in a central bore in the piercing head. Additionally, the localized weakenings may be provided by bound collars on the piercing head. The shearing regions are progressively stronger in a direction from the front of the piercing head so that they will shear consecutively as the head pierces successive shells of a multi-shell target.
