U.S. Army Stryker Combat Vehicles to Be Equipped With Allegheny Technologies’ ATI 500-MIL(TM) Armor Steel

Allegheny Technologies Incorporated's (NYSE:ATI) next-generation ATI 500-MIL(TM) armor steel has been selected for an armored situational awareness kit on the U.S. Army's Stryker Light Armored Vehicles, marking the first major legacy-vehicle military application for this newly developed specialty metal.

The new add-on kit, known as the StrykShield(TM), is comprised of front and side transparent armor windows that are mounted in a framework built with ATI 500-MIL high-hard armor steel. Produced by Carapace Armor Technology, the StrykShield kit provides increased visibility and situational awareness for Stryker crews, while providing full ballistic and blast protection.

"Carapace selected ATI 500-MIL steel due to its exceptional ballistic performance, improved flatness over other high-hard armor products, minimal distortion after cutting, and unique auto-tempering capability," said Pat Hassey, ATI Chairman, President and Chief Executive Officer. "This first use of ATI 500-MIL armor steel on a legacy vehicle system demonstrates the alloy's adaptability to the most demanding applications, and underscores its availability in quantity at a time when the need for high-hard specialty metals remains strong."

The StrykShield kit has been successfully fielded and battle tested in Iraq for two years. The U.S. Army's Rapid Equipping Force has ordered 690 StrykShield kits for deployment on Stryker vehicles.

Allegheny Technologies' ATI 500-MIL steel is the first new, high-hard steel armor developed in America since the Vietnam conflict, and meets new U.S. MIL-DTL-46100E high-hard specifications for ballistic performance. It protects against such threats as armor-piercing rounds while also offering good blast-resistance properties.

In addition to its use on a full range of ground vehicles, ATI 500-MIL armor steel can be installed on above-deck structures for ships, and aboard aircraft in perforated versions.

ATI 500-MIL armor steel is available in plate form, with sheet product currently in development by ATI. The specialty armor plate is offered in thickness gauges from 3/16 inch to 1 inch (0.5 to 2.5 cm), and in sizes as large as 96 X 300 inches (243 X 763 cm), with customized manufacturing solutions available to meet customers' specific needs.
