The expansion takes the facility from 40,000 to 50,000 square feet as HII responds to demand for autonomous maritime platforms. Lionfish, a small unmanned undersea vehicle based on the commercial REMUS 300, is already in production, and the Navy awarded HII an option-year contract for further deliveries in July.
The site will also support production of the REMUS 620 underwater vehicle and work on ROMULUS unmanned surface vessels. HII plans to integrate its Odyssey autonomy software, simulation and modeling capabilities, and autonomy hardware for ROMULUS at the expanded campus.
“By bringing together advanced unmanned platforms, autonomy, integration, simulation and modeling capabilities, we are expanding our ability to deliver the maritime systems our customers need while continuing to create high-quality jobs here in Massachusetts,” said Duane Fotheringham, president of unmanned systems in HII’s Mission Technologies division. HII said it employs about 300 people in Pocasset and has added 50 staff there so far in 2026.
“HII’s continued growth on Cape Cod demonstrates how investments in advanced maritime technology can strengthen our national security while supporting good jobs and economic opportunity here in Massachusetts,” said U.S. Representative Bill Keating, who attended the expansion ceremony. Keating also spoke at the original opening of HII’s Pocasset production facility in 2014.
HII said it has delivered more than 750 REMUS underwater vehicles to customers in over 30 countries, including 14 NATO members. The company said more than 90% of the REMUS systems delivered over the past 25 years remain in active service.
