AI summary

A capacitive reactive armor assembly for shielding a vehicle is disclosed herein. The capacitive reactive armor includes, but is not limited to, a first flyer plate, a second flyer plate, and a capacitor positioned between the first flyer plate and the second flyer plate. The capacitor is configured to store an electric charge and to explosively short circuit when the capacitor is penetrated while the capacitor is electrically charged. The explosive release of energy from the capacitor pushes the first and second flyer plates apart interfering with the penetration of a shaped charge jet or ballistic penetrator.
