Huntington Ingalls (HII) Wins $347M Deal to Aid Lionfish Program

Huntington Ingalls Industries Inc.’s HII Mission Technologies segment recently secured a contract to develop nine small unmanned undersea vehicles (“SUUV”) for the U.S. Navy’s Lionfish System program. The program is used to conduct intelligence gathering for expeditionary marine countermeasure missions.

Huntington Ingalls is a prominent manufacturer of unmanned undersea vehicles (“UUV”) worldwide. Serving customers in more than 30 countries, HII provides design, autonomy, manufacturing, testing, operations and sustainment of unmanned systems, including UUVs and unmanned surface vessels (USV).

Its REMUS family of UUVs are low logistics UUV that can be rapidly deployed from any vessel of opportunity, with their common usage in mine countermeasures, search and recovery and antisubmarine warfare.
Notably, the U.S. Navy’s Lionfish System is based on HII's REMUS 300 UUV and 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.
