US Navy’s new weapon to turn helicopters into sea mine killers

The US Navy has awarded a $10.5 million contract modification to BAE Systems for the delivery of MK64 Mod 0 explosive destructors and fiber optic spool kits for the Airborne Mine Neutralization System (AMNS) known as Archerfish. This advanced underwater weapon system, deployable from MH-60S helicopters, unmanned surface vehicles, and small boats, is designed to neutralize naval mines with precision and speed, reducing mine clearance time by four times compared to traditional methods. Archerfish employs a dual-mode propulsion system and integrates a directed-energy warhead with advanced acoustic positioning, electronic scanning sonar, and visual imaging, transmitting live video and sonar feedback via fiber-optic cable to enable real-time operator control and precise target identification. Developed originally for the Royal Navy and adopted by the US Navy, Archerfish is a modular, lightweight, and cost-efficient system optimized for flexibility and rapid deployment. Its design includes an Insensitive Munition warhead for safer handling and storage, and a reusable inert training version to facilitate multiple practice exercises. The system’s compact size allows for increased mission endurance by enabling more weapons to be carried onboard. The contract, managed by Naval Sea Systems Command (NAVSEA), underscores Archerfish’s critical role in the US Navy’s airborne mine countermeasure strategy and highlights the growing importance of remote-controlled neutralizers in enhancing speed, accuracy, and personnel safety in maritime mine warfare operations.
