MINNEAPOLIS -- Alliant Techsystems (NYSE: ATK) has received a $52 million order for 120mm training tank ammunition from the U.S. Army. The award is for the third year of a four-year contract.

The 120mm training ammunition, used by the M1A1/A2 Abrams main battle tank, include the M865 kinetic energy and the M1002 multi-purpose anti-tank training rounds.
