ABSTRACT:
A two-stage, shaped charge projectile having a rear principal charge and a front secondary smaller charge with an initiator-fuse assembly for sequentially igniting the secondary and principal charges so that the secondary charge is first ignited, followed by ignition of the principal charge after a predetermined time delay. The secondary charge is maintained at a set distance in front of the principal charge which is shielded from rearwardly expanding combustion gases and rearwardly flying debris when the secondary charge is ignited, with these gases and debris being diverted away from the principal charge after the secondary charge has been detonated.
