Medium caliber orders included a broad range of purchases for 20mm, 25mm, 30mm and LW30mm ammunition for multiple services for use with air, sea and land weapons platforms. These contracts are awarded through the U.S. Army Maneuver Ammunition Systems in its role as the Single Manager for Conventional Ammunition.

Our development and production of highly reliable and effective ammunition for the warfighter spans a wide spectrum of technologies and capabilities, said Dan Olson, vice president and general manager for the company s Armament Systems division of the Defense Systems Group. Whether we are creating new, or producing proven ammunition types, our focus on our mission remains constant as we provide superior armaments and services to those who defend their nation s security.

International medium caliber orders span a range of 25mm cartridges, including the M791 Armor Piercing Discarding Sabot with Tracer and its ballistically-matched, target practice counterpart M793 which provides realistic training at a low cost.
