Abrams Main Battle Tank Armor
arl.army.mil

The special armors for the original M1 Abrams tank and all subsequent variants were designed together with engineers from General Dynamics Land Systems [link] and scientists and engineers at the U.S. Army Research Laboratory. These armors were developed from potential patents from existing secrecy orders based on technology of U.S. and U.K. origin. These armors are unique, still highly classified, and provide protection levels that render U.S. main battle tanks the most survivable in the world today.

Background:

A new armor-defeat mechanism was discovered which provides revolutionary enhancements to heavy armor protection. With the discovery of this technology and its potential came the requirement to understand the mechanics and interactions between the penetrator and target. Comprehensive terminal ballistics investigations were made to elucidate the underlying mechanisms. The use of continuum mechanics codes, physical and mathematical modeling, and experimentation allowed the new concept to be ultimately exploited as a viable armor technology.

Technology:

These technologies have been granted secrecy orders recognizing them as patentable concepts and are still the main defeat mechanisms for the protection of the Abrams main battle tank. These defeat mechanisms feature a unique combination of geometry, material type, and fabrication method. They have been applied as the main, side, and bustle armor for the M1, M1A1, and M1A2 Abrams tanks.
