Abstract: Disclosed is a modular armor structure for a vehicle, the structure having n external rectangular frame containing a series of spaced parallel beams tilted and overlapping so as to form a continuous barrier against horizontally flying projectiles, the beams having a relatively flat outboard region and a curved inboard region to trap fragments and debris of projectiles shattering against the outboard region of the beams.

Abstract: A lightweight, economical, add-on armor plate, ballistic spall liner, installable on the inner surfaces of unprotected vehicles, structures, or other craft. The spall liner provides additional protection to vehicle occupants and internal equipment from the risk of injury or damage due to flying metallic debris, "spall", caused by ballistic damage to the vehicles or the structure's interior when a munitions-type projectile penetrates a wall. The spall liner is a laminate made from layers of high tensile strength, woven fabric such as polyaramid fabric or ballistic nylon which are bonded together with at least one reinforcing layer of martensite sheet steel interposed between the woven fabric layers. The spall liner controls the spall generated by the penetration of a munitions-type projectile by dissipating the projectile's force, framentizing the projectile, and trapping the fragments in the spall liner's interior.

Abstract: A shatter resistant armor-piercing military projectile is disclosed. The struction comprises a plurality of high strength metallic lamellae interconnected with a high ductility alloy selected to provide an impact energy management system capable of maintaining the projectile's structural integrity during adverse operating conditions, such as oblique impact on spaced or solid armor targets.
