Orbital ATK Demonstrates Mk44 Bushmaster Chain Gun in 30mm and 40mm Configurations
DULLES, Va. — Orbital ATK provided a live demonstration of its MK44 Bushmaster Chain Gun firing a variety of both 30mm and 40mm ammunition during its Bushmaster User Conference at Big Sandy Range, Ariz., the company said in a June 27 release. The gathering of domestic and international attendees watched as the Mk44 guns hit targets before and after a rapid changeover from a 30mm to a 40mm configuration.
The Mk44 Chain Gun will be featured on the 2017 season premiere episode of “GunnyTime with R. Lee Ermey” on the Outdoor Channel beginning June 28. It will feature Ermey firing the Mk44 Chain Gun with Orbital ATK’s 30mm and 40mm Airbursting Ammunition.
“The Mk44 is quickly becoming the most sought-after medium-caliber cannon,” said Dan Olson, vice president and general manager of the Armament Systems Division of Orbital ATK’s Defense Systems Group. “Today’s battlefield call for greater standoff and increased firepower is driving new combat vehicle platforms to include larger guns and advanced ammunition types. The same is true for upgrade programs.”
Attendees of the live-fire demonstration saw the Mk44 Chain Gun, mounted to a Kongsberg Protector Turret and General Dynamics Land Systems Light Armored Vehicle, engage a variety of adobe, concrete block and steel panel targets in 30mm configuration using high-explosive incendiary ammunition. Additionally, the Mk44 was set up with Orbital ATK’s proprietary air-bursting munition fuze-setting equipment to demonstrate the gun’s ability to precisely fire several rounds in rapid succession with point-bursting accuracy, both horizontally and vertically across the target.
Along with the air-bursting capability, Orbital ATK is developing other precision technologies for its medium-caliber ammunition, including proximity detonating and command guidance that are compatible with its medium-caliber cannons. These two new advanced capabilities will be demonstrated at the Bushmaster Users Conference in 2018 and 2019, respectively.
The MK44 Bushmaster Chain Gun is available new as a 30mm or 40mm weapon. At the completion of the 30mm demonstration, the system was easily “up-gunned” in about an hour’s time and readied to fire 40mm ammunition. The demonstration in the 40mm configuration showed the increased firepower that the 40mm cannon and ammunition provided engaged against similar target panels. The weapon also fired Orbital ATK’s newly developed 40mm Programmable Air Burst Munitions with dramatic effects on a replicated target set in a combat-defilade position.
