POCASSET, Mass. -- HII has expanded its unmanned maritime systems manufacturing campus in Pocasset, Massachusetts, adding 10,000 square feet to its existing 40,000-square-foot facility to meet rising global demand for autonomous ocean platforms.
The expansion increases production capacity for several advanced maritime vehicles, including the REMUS line of unmanned underwater vehicles (UUVs) and the ROMULUS family of unmanned surface vessels (USVs). Crucially, the site will support ongoing manufacturing of the Lionfish small unmanned undersea vehicle for the U.S. Navy. The Lionfish system, derived from HII’s commercial REMUS 300 design, received continued production funding via a Navy option-year contract awarded in July. Production for the larger REMUS 620 UUV will also run through the site.
Beyond physical vehicle assembly, the updated campus will handle integration of HII's proprietary Odyssey Autonomous Control Solutions software. The software platform incorporates autonomy hardware for surface vessels alongside simulation and modeling tools intended to streamline multi-vehicle operations across complex maritime environments.
The expansion increases HII’s ability to produce and integrate unmanned maritime systems at a time when the U.S. Navy and other customers are increasing investment in distributed undersea and surface capabilities. Maintaining Lionfish production at the site provides a direct link to a Navy program, while capacity for REMUS 620 and ROMULUS systems gives HII additional room to address demand for larger and more capable autonomous platforms. Integrating the Odyssey autonomy system at the same facility also allows HII to combine vehicle manufacturing with software and multi-vehicle control capabilities, an approach that could support broader adoption of autonomous systems for surveillance, mine countermeasures, undersea warfare, and other maritime missions.
