U.S. Navy Expands Lionfish Unmanned Underwater Vehicle Production with HII
The U.S. Navy awarded HII an option year contract for the Lionfish small unmanned undersea vehicle (SUUV), based on the REMUS 300 platform. The program, which reached 42 vehicles built, could scale to 200 units worth over $347 million. Lionfish supports mine countermeasures, ISR, anti-submarine warfare, and electronic warfare. It is the Navy’s first UUV to transition from OTA prototype to full production and the only cyber-compliant UUV in production. HII also partnered with Halimar Shipyard to boost production capacity.
