MESA, Ariz. – Northrop Grumman Corporation has entered full-rate production to deliver Mk44 Stretch Bushmaster Chain Guns for the U.S. Marine Corps’ new Amphibious Combat Vehicles (ACVs). The Mk44S will be integrated into the Kongsberg remote turret used on the Amphibious Combat Vehicle 30mm program (ACV-30), significantly improving firepower for the Marines.
The Mk44S is a medium-caliber weapon designed to fire 30x173mm ammunition and can be upgraded to fire 40mm rounds. It offers flexibility and reliability and is ideal for use with Northrop Grumman’s advanced programmable munitions.
The Mk44S includes the option to upgrade from 30mm to 40mm by simply changing the barrel and a few key parts, allowing for future flexibility.
Production is underway at Northrop Grumman’s Mesa, Arizona, facility.
Dave Fine, vice president, armament systems, Northrop Grumman said, “The Mk44 Bushmaster Chain Gun delivers unmatched firepower and reliability in even the most unforgiving conditions. By integrating this proven capability into the Amphibious Combat Vehicle program, we’re equipping Marines with the tools they need to dominate the battlefield and stay ahead of evolving threats.”
