Northrop Grumman has begun full-rate production of Mk44 Stretch Bushmaster Chain Guns for the US Marine Corps’ new Amphibious Combat Vehicles (ACVs).
The Mk44s will be mounted on the Kongsberg-made remote turret of the ACV-30, providing the marines with increased firepower.
Supporting all NATO-standard 30x173mm ammunition, including advanced rounds from Northrop Grumman, the system provides extended range and consistent performance.
It can also be upgraded to 40mm by replacing the barrel and select components, allowing for future mission flexibility.
“The Mk44 Bushmaster Chain Gun delivers unmatched firepower and reliability in even the most unforgiving conditions,” VP of armament systems at Northrop Grumman Dave Fine stated.
“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.”
The US Marine Corps acquired additional ACVs from BAE Systems under a $256.8-million contract signed in 2023.
The deal allocates $145.3 million for 25 ACV personnel variants and $111.5 million for more than 15 ACV combat variants.
Recent Projects
Northrop Grumman has continued work on multiple initiatives with US military forces.
Earlier this month, the company tested the integration of its AN/AQS-24 anti-mine sonar system with an unmanned surface vessel for the US Navy.
The trial is part of efforts to develop an uncrewed maritime platform equipped with a towed mine countermeasures system.
Moreover, the US Air Force and Northrop Grumman completed a separation test of the Stand-In Attack Weapon from an F-16.
The test verified the missile’s flight characteristics and aerodynamics, advancing its planned integration with several platforms, including the F-35.
In addition, Northrop Grumman secured a contract valued at more than $200 million from the US Army to produce XM1211 High Explosive Proximity rounds, a medium-caliber munition designed to support short-range defense against small unmanned aerial systems.
