Perforated plate armor (10) for protecting an object (12) from damage includes outer and inner perforated steel plates (14) and (18) which have associated patterns of holes (16,20). These perforated steel plates (14,18) are heat treated to have hardened surfaces and a more ductile core and are spaced with respect to each other at outer and inner locations with respect to the object (12) to be protected. The patterns of holes (16,20) of the perforated steel plates (14,18) are offset with respect to each other to prevent straight line penetration of any particle through both plates. An inner backing plate (28) preferably made of aluminum is also provided to stop any particles that might penetrate both perforated steel plates (14,18). Fillers (22,24) and connectors (26) space the outer and inner perforated steel plates (14,18) and the aluminum backing plate (28) with respect to each other.
