HII is awarded $347 Million U.S Navy Lionfish small UUV contract

McLean, Va., October 11, 2023 — HII (NYSE: HII) announced today that its Mission Technologies division was awarded a contract to build nine small unmanned undersea vehicles (SUUV) for the U.S. Navy’s Lionfish System program. The contract has the potential to grow to as many as 200 vehicles over the next five years with a total value of more than $347 million.

The Lionfish System, based on HII’s REMUS 300, is a highly portable, two-person SUUV with an open architecture design and versatile payload options. In early 2022, REMUS 300 was chosen as the Navy’s official program of record for the next-generation SUUV.

Administered by Naval Sea Systems Command, this contract provides for the delivery and support of the Navy’s next generation SUUVs, as well as afloat and auxiliary support equipment and engineering services. The vehicles, incorporating the latest in autonomous and unmanned technology, will conduct critical undersea missions for the Navy.

“Lionfish provides increased capability and interoperability that aligns with the Navy’s undersea priorities, and we look forward to delivering next-generation vehicles that can readily adapt to and support a variety of mission needs,” said Andy Green, executive vice president of HII and president of Mission Technologies.

“We are pleased with the Navy’s decision to support a combat-proven technology, essential to the Navy’s undersea mission,” said Duane Fotheringham, president of Mission Technologies’ Unmanned Systems business group. “Our team is committed to delivering fully capable vehicles that will enhance the effectiveness of the warfighter against emerging threats.” 

The Lionfish System was developed through an innovative process with the Department of Defense’s Defense Innovation Unit and the Navy that incorporated feedback from multiple user groups to uniquely meet the needs of the warfighters.
