HII expands Massachusetts unmanned systems production facility

HII is expanding its unmanned-systems production facility in Pocasset, Massachusetts, to increase capacity for autonomous maritime platforms and associated engineering work. The site employs about 300 people and added 50 staff during 2026, while maintaining research ties with the Woods Hole Oceanographic Institution on autonomous underwater technology. The investment supports rising U.S. demand for uncrewed surface and undersea systems, but the company did not tie the expansion to a single disclosed production quantity or delivery schedule, so its impact will span multiple development and procurement efforts.
