Northrop Grumman Unveils Game-Changing M230LF Dual Feed Bushmaster Chain Gun

In a world where military technology is rapidly evolving, Northrop Grumman has introduced a new level of innovation with the unveiling of its M230LF Dual Feed Bushmaster Chain Gun. This advanced weapon, an enhancement of the existing M230LF, adds a crucial dual-feed capability to the chain gun system, enabling greater flexibility in modern warfare. Designed to serve both counter-uncrewed aerial systems (C-UAS) and ground combat roles, this new iteration is set to change the landscape of medium-calibre combat engagement.

At its core, the M230LF remains a 30x113mm calibre chain gun. The unique addition, however, is the ability to switch between two different types of ammunition in real-time, eliminating the need for preloaded, mixed ammo belts. This breakthrough in ammunition versatility means that soldiers can respond to multiple threats—whether airborne drones or armoured vehicles—without wasting time or resources on reloading. This capacity to change between rounds optimizes mission outcomes, especially in high-stakes situations where split-second decisions can alter the course of combat.

Combat Versatility and Tactical Flexibility

One of the standout features of the M230LF Dual Feed Chain Gun is its compatibility with a variety of specialized ammunition types, tailored to different mission requirements. For anti-aircraft and C-UAS operations, the XM1211 proximity-fuzed rounds are the ammunition of choice. These rounds are designed to detonate near aerial targets, such as drones, making them ideal for neutralizing unmanned threats from a distance. On the other hand, the XM1198 high explosive, dual-purpose rounds are designed for anti-armour combat, delivering devastating firepower against ground vehicles and other fortified structures.

The integration of these specialized munitions, combined with the ability to switch between them seamlessly, positions the M230LF Dual Feed as a formidable asset on the battlefield. Soldiers can go from targeting drones in the sky to engaging armoured targets on the ground in an instant, all without having to change out the weapon’s ammunition belt. This level of adaptability is rare in medium-calibre systems and promises to significantly increase operational efficiency in diverse combat scenarios.

Built on Decades of Battle-Proven Experience

Despite its modernized features, the M230LF Dual Feed Bushmaster Chain Gun builds on a long legacy of Northrop Grumman’s battle-tested Bushmaster line, which has been in service for over 50 years. Dave Fine, Vice President of Armament Systems at Northrop Grumman, underscores this connection between past and present. "The M230LF Dual Feed Bushmaster Chain Gun offers new flexibility by switching between ammunition paths using dual-feed technology. Using advanced technology combined with five decades of battle-proven experience, this next-generation cannon will empower operators to quickly respond to threats."

This weapon represents the world’s first medium-calibre chain gun with a dual-feed system, making it not only a breakthrough in ammunition flexibility but also in reliability. The Bushmaster series has long been known for its ruggedness and dependability, and the M230LF Dual Feed continues this tradition while embracing new technology to meet the demands of modern warfare.

Operational Readiness and Compatibility

The M230LF Dual Feed is currently at Technology Readiness Level 6, meaning it is close to final live-fire testing. Early 2025 will see the first demonstrations of this new chain gun in action, marking the final step before it becomes fully operational. For militaries and defense operators already using the single-feed M230LF, the transition to the dual-feed version will be seamless. With around 60% of the parts being interchangeable between the two models, existing logistics, repair processes, and training programs can remain largely unchanged.

Moreover, the weight profile of the M230LF Dual Feed remains similar to its predecessor, ensuring that vehicles and platforms currently using the single-feed version will not require significant modifications. This ease of integration makes the upgrade not only highly appealing but also practical for defense forces around the world.

Looking to the Future

As Northrop Grumman continues production of both the single-feed and dual-feed variants, it is clear that the company is committed to offering its customers the best of both worlds. For operators who prefer the tried-and-true single-feed model, that option remains available. However, for those looking to increase operational versatility and shorten response times, the M230LF Dual Feed represents the next step in chain gun evolution.

The future of combat is increasingly dynamic, with a wide range of threats emerging from both the skies and the ground. Northrop Grumman’s M230LF Dual Feed Bushmaster Chain Gun is a response to that changing environment, offering advanced capabilities in a familiar, reliable package. As the military prepares for the challenges of the 21st century, innovations like this will be crucial in maintaining the upper hand on the battlefield.
