FN unveils twin M3M Endurance mount for C-UAV use
Belgian manufacturer FN unveiled a twin 12.7-millimetre M3M Endurance heavy-machine-gun mount for counter-unmanned-aircraft use at Euronaval 2026 in Paris. The crew-served configuration can be installed at fixed sites or on 4×4 vehicles and surface vessels, with two independently triggered guns delivering a combined rate of roughly 2,200 rounds per minute. FN says the upgraded Endurance weapon extends weapon service life to 60,000 rounds and maintenance intervals to 15,000 rounds. The company described the design as customer-driven and expected live-fire trials before the end of 2026, but had not identified a buyer or announced serial production.
