Northrop Grumman Corporation is developing its next-generation M230 Link Fed (M230LF) Dual Feed Bushmaster Chain Gun, offering two ammunition feed paths for the first time. This new 30x113mm medium calibre chain gun is a variant of the M230LF chain gun to counter uncrewed aerial threats (C-UAS) and ground engagements.
The M230LF is currently at Technology Readiness Level 6. Meeting this threshold enables the capability to undergo live fire demonstrations that are currently scheduled for early 2025.
By offering a dual feed, the need for mixed ammunition belts in a single feed is eliminated. A standard recommended ammunition load includes XM1211 proximity fuzed rounds for C-UAS and XM1198 high explosive, dual purpose rounds for anti-armor capability. The dual feed system gives operators the option to change between advanced ammunition rounds with the ‘flip of a switch’.
For operators already using the M230LF, Northrop Grumman says the Bushmaster loads out at a similar weight to the single feed M230LF and features 60 percent-part commonality. Single feed M230LF cannons will continue to be produced for customers that prefer that option.
