A system for aiming a selectively aimable warhead (SAW) at a target by explosively deforming the warhead into a shape desirable for directionality. Twenty-four explosive forming charges are located around the circumference of the warhead and run the entire length of the warhead. The proximity fuze selects one sector out of 24 as the direction aim. Having selected a sector in the azimuth, the forming charge in that sector plus the adjacent two forming charges are initiated simultaneously. After a time delay interval sufficient to allow the warhead to deform (about ½millisecond to 1 millisecond), warhead boosters located furthest from the target (or 180 degrees from the forming charges) and on each end of the warhead, are initiated simultaneously. The warhead is detonated generating a high velocity fragment beam towards the target.
