MINNEAPOLIS -- Alliant Techsystems has received orders totaling $372 million to produce 5.56mm, 7.62mm and .50-caliber ammunition for the U.S. Army Contracting Command in Rock Island, Ill. This is the first significant order in the second year of a four-year contract, with additional orders expected during this fiscal year.

ATK operates the Lake City Army Ammunition Plant (LCAAP) in Independence, Mo., where the rounds will be produced.

"ATK has demonstrated the capability to support the tremendous increase in demand, while in parallel, modernizing the facility," said Mark Hissong, Vice President and General Manager of ATK Small Caliber Systems. "Our daily focus on continuous improvement in all of our processes has resulted in the world's best small caliber ammunition and a facility that will support the warfighter for years to come."

ATK is a premier aerospace and defense company with more than 18,000 employees in 22 states, Puerto Rico and internationally, and revenues of approximately $4.8 billion. News and information can be found on the Internet at www.atk.com.
