Northrop Grumman Unveils M230LF Dual Feed Bushmaster Chain Gun.
On October 9, 2024, Northrop Grumman unveiled the M230LF Dual Feed Bushmaster, a medium-caliber dual-feed chain gun that, for the first time, allows operators to instantly switch between two types of ammunition suited for uncrewed aerial threats (C-UAS) and ground engagements. This innovation enhances operational efficiency and accuracy by eliminating the need for mixed ammunition belts.

Northrop Grumman Corporation, a leading manufacturer of medium-caliber cannons, introduced the M230 Link Fed (M230LF) Dual Feed Bushmaster Chain Gun. Designed to meet modern demands for ground combat and defense against uncrewed aerial threats, this new 30x113 mm cannon offers a dual-feed capability for the first time, a significant technical advancement that lets operators seamlessly switch between two types of ammunition based on the target. This innovation removes the need for mixed ammunition belts in a single feed, thus increasing engagement efficiency and precision.
The M230LF’s dual-feed technology allows operators to switch easily between two recommended rounds: the XM1211 proximity-fused rounds, optimized to counter uncrewed aerial threats, and the XM1198 high-explosive, dual-purpose rounds for anti-armor ground capabilities. This system simplifies logistics by allowing better ammunition management and enhances the forces’ ability to adapt to various threats in real time. Currently, the M230LF has reached Technology Readiness Level 6 (TRL 6), marking its operational maturity and paving the way for live-fire demonstrations scheduled for early 2025.
Dave Fine, vice president of armament systems at Northrop Grumman, emphasized that the M230LF Dual Feed Bushmaster represents a significant advancement in flexibility for the armed forces: “By combining advanced technology and five decades of combat-proven experience, this next-generation cannon will enable operators to respond faster to threats, with the reliability the Bushmaster line is known for.” According to Fine, this innovation is the latest example of Northrop Grumman’s ability to adapt to the evolving tactical needs of the battlefield.
With a design that maintains a similar weight to the single-feed M230LF model, the new dual-feed cannon shares 60% of its parts with existing models. This continuity in design ensures simplified maintenance, allowing for an easy transition for those already using M230LF systems, minimizing maintenance costs. Northrop Grumman will continue to produce the single-feed version to accommodate the preferences of certain users.
As a global leader in the aerospace and defense sectors, Northrop Grumman strives to provide innovative solutions to today’s security challenges. By offering operators new capabilities for rapid adaptation and response to modern threats, the M230LF Dual Feed Bushmaster is positioned as a key element in Northrop Grumman’s strategy to equip armed forces with reliable, high-performance tools tailored to tomorrow’s challenges.
