HII has been awarded an option year production contract for the U.S. Navy’s next-generation program of record, the Lionfish Small Unmanned Undersea Vehicle (SUUV).
The vehicle is based on the commercial REMUS 300 platform, which was originally developed as part of a rapid prototyping initiative in collaboration with the U.S. Navy and the Defense Innovation Unit. Designed to address a broad range of undersea warfare missions, the platform supports mine countermeasures, intelligence, surveillance and reconnaissance, anti-submarine warfare, and electronic warfare operations.
This latest option year contract continues to build the momentum of the production program, which marked a major milestone at the close of 2025 with the completion of the 42nd vehicle at the Pocasset facility. The five-year program could scale to as many as 200 vehicles, with a total contract value exceeding $347 million.
Duane Fotheringham, president of the Unmanned Systems group in HII’s Mission Technologies division, “The decision to exercise this option year production of the Lionfish program reflects the U.S. Navy’s confidence in the platform’s operational performance, reliability and adaptability. Our team remains focused on delivering advanced autonomous systems that provide sailors and marines with critical undersea warfare capabilities in support of evolving mission requirements.”
