Alliant Techsystems has received a $77 million, three-year contract to proceed with the second phase of a project to develop new ammunition rounds for the U.S. Army’s Abrams battle tank. The round is expected to enter full-rate production once this phase is completed. Minneapolis-based ATK, whose ammunition division has headquarters in Clearfield, had the Army contract to develop the first phase of the “advanced kinetic energy” 120 mm tank round. It secured the phase-two contract after an industry competition that involved a ballistic demonstration test and a shoot-off. Salt Lake Tribune
