HII has been awarded an option year production contract for the U.S. Navy's Lionfish small unmanned undersea vehicle (SUUV), which is based on the REMUS 300 platform. This contract, announced on June 7, 2026, continues the momentum of the Lionfish program, which achieved a significant milestone with the completion of its 42nd vehicle at HII’s Pocasset facility by the end of 2025. The five-year program could scale to a total of 200 vehicles, with a contract value exceeding $347 million.
The Lionfish SUUV is designed for various undersea warfare missions, including mine countermeasures, intelligence, surveillance and reconnaissance (ISR), anti-submarine warfare, and electronic warfare operations. The U.S. Navy's decision to exercise this option year contract reflects confidence in the platform's operational performance and adaptability, as stated by Duane Fotheringham, president of HII’s Unmanned Systems group.
Looking ahead, HII aims to enhance the capabilities of the Lionfish program to meet evolving mission requirements for sailors and marines. No further timeline was disclosed at the time of publication, but the continued investment in this program indicates a strong commitment to advancing autonomous systems in naval operations.
Editor's Note
The award of this contract signals a growing trend in military procurement towards autonomous systems for undersea operations. As defense budgets increase, companies like HII are likely to see more opportunities for contracts that enhance naval capabilities. Monitoring the development and deployment of such technologies will be crucial for understanding future military strategies.
