Application and Performance Characteristics of Aluminum Armor Plate for the Hull Construction of Current and Future Military Tactical Vehicles

The application of aluminum armor plate for military vehicles has significantly increased during the past decade. Both US Army and Marine Corps place great emphasis on lighter weight, higher agility and fuel efficiency as well as improved survivability. This requires lighter armor which makes aluminum armor plate a major structural material. Recent US ARL investigations indicate that when properly designed, aluminum armor plate can indeed provide the required level of ballistic protection at lighter weight. Consequently, in the past few years, a number of new alloys and tempers have been added to military armor plate specifications. One tactical vehicle with aluminum hull i.e. MRAP RG-33 has already been deployed and is currently operating in both Afghanistan and Iraq. Also, one of the three selected JLTV designs uses aluminum hull.
