Alliant Techsystems announced Thursday that it has been awarded a $105 million contract to supply non-standard ammunition for the security forces of Afghanistan.

Brian Grace, a spokesman for the Eden Prairie-based company, said this type of ammunition is not made in the United States but would be manufactured by suppliers in Eastern Europe.

This is Alliant's second major contract from the U.S. Army to produce ammunition for Afghan forces, with the first contract coming last December. It was valued at $87 million.
