Abstract:

The scope of the study includes testing of various materials to determine their effectiveness in preventing complete penetration of a single 7.62 mm NATO round, fired from a distance of 125 feet. As an added item of interest, additional 4-shot bursts were fired at the same spot to determine what effect this would have on the materials. The Air Force is currently upgrading their security requirements in the Weapons Storage Areas WSA and the Aircraft Alert Areas AAA at various Air Force Bases. A portion of this upgrading requires hardening of walls to meet the criteria presented above. Although there are many reports of this type, covering testing of various materials, they do not fit the immediate criteria required for these projects. The purpose of this report is to determine the adequacy of the hardening criteria furnished by the Air Force, and to produce economies of design where the criteria could be reduced.
