While lots of exotic new armor materials have emerged, the military remains mosdy committed to the rolled homogeneous armor steel for its combat vehicles generally because of its proven protective qualities and its relativdy low cost compared to next-generation technologies. DARPA officials instinctively suspect that some of the answers to the Army's armor problems may come from companies or individuals who currently lack the means to present or market their technologies to the Defense Department. The materials, dubbed nano-laminated alloys, can be added to the core structure of a vehicle to make it even more resistant to enemy fire, therefore reducing the need for add-on appliqu armor, says Christina Lomasney, scientist and founder of Modumetal, based in Seattle The materials in nano-laminated alloys are measured on a nanometer scale, she explains.
