Edina-based Alliant Techsystems, the largest supplier of ammunition to the U.S. military, has received an additional $415.6 million in military small-caliber ammunition orders and modernization funding for the Lake City Army Ammunition plant in Missouri, the company announced today.

In fiscal year 2008, ATK delivered 1.4 billion rounds of military small-caliber ammunition, and expects to deliver roughly the same amount in the next fiscal year.

"We are proud of the role we play in supporting the men and women in uniform," said ATK Armament Systems President Mark DeYoung, "and we're grateful to have the opportunity to continue to provide them with high-quality ammunition they can count on."

ATK has more than 17,000 employees in 21 states and more than $4.1 billion in revenue.
