HII Expands Unmanned Maritime Systems Facility in Massachusetts by 25%
HII, a global leader in shipbuilding and a major defense contractor, has announced a significant expansion of its unmanned maritime systems facility in Pocasset, Massachusetts. The facility has increased its manufacturing footprint by 25%, adding 10,000 square feet of dedicated space for the development, production, and integration of advanced autonomous underwater and surface vehicles. This expansion is specifically designed to enhance capacity for key programs, including the U.S. Navy’s Lionfish small uncrewed undersea vehicle (UUV) program.
The addition of manufacturing space brings the Pocasset facility’s total area from 40,000 to 50,000 square feet. This enhanced capacity is crucial for HII’s Unmanned Systems group, which operates within its Mission Technologies division. The site is a central hub for the company’s comprehensive portfolio of autonomous maritime systems, encompassing its widely recognized REMUS family of uncrewed underwater vehicles and its ROMULUS uncrewed surface vessels (USVs). Beyond physical vehicle production, the facility also specializes in the development of sophisticated autonomy software and associated modeling and simulation tools, essential for planning and testing complex autonomous operations.
A primary driver for this expansion is the accelerating demand for the U.S. Navy’s Lionfish program. The Lionfish is a small uncrewed undersea vehicle, derived from HII’s commercial REMUS 300 design, which is already in production. The Navy underscored its commitment to the program by exercising another contract option for Lionfish production in July. The expanded plant is poised to further support this critical program and will also facilitate the manufacturing of the larger REMUS 620 UUV, a new platform designed for extended endurance and increased payload capacity, broadening its potential applications for naval and scientific missions.
Beyond vehicle manufacturing, the Pocasset facility serves as a key integration point for HII’s Odyssey Autonomous Control Solutions. This suite of autonomy hardware and software is engineered to enable advanced mission execution across various vehicle types, including the ROMULUS surface vessels. HII emphasizes that this software is developed for versatility, supporting diverse missions and offering robust simulation and modeling tools. These tools are vital for effective planning, rigorous testing, and safe deployment of autonomous operations in challenging maritime environments, significantly reducing risks and increasing operational efficiency for customers.
Duane Fotheringham, president of the Unmanned Systems group within HII’s Mission Technologies division, highlighted the strategic importance of the expansion. He stated,“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.”This statement underscores HII’s commitment not only to technological advancement and meeting customer demands but also to fostering economic growth and skilled employment in the region.
The expansion reflects HII’s continued investment in its workforce and the local economy. The company currently employs approximately 300 individuals at its Pocasset facility and has added about 50 new employees in recent periods, illustrating the growth trajectory of its unmanned systems sector. HII’s operations in the area maintain long-standing ties with the Woods Hole Oceanographic Institution (WHOI), a world-renowned center for ocean research. This collaboration has fostered significant advancements in autonomous underwater technology, leveraging academic expertise with industrial production capabilities.
The REMUS family of UUVs, a cornerstone of HII’s unmanned offerings, is deployed across a broad spectrum of applications, including military operations, critical oceanographic research, scientific exploration, and environmental monitoring. HII has reported delivering over 750 REMUS vehicles to customers in more than 30 countries, including 14 NATO member states, testifying to its global reach and reliability. The company also notes that more than 90% of the systems delivered over the past 25 years remain in active service, demonstrating the durability and enduring utility of its technology. The recent expansion further solidifies HII’s capacity to meet the growing global demand for both underwater and surface autonomous systems, developing a broader range of maritime platforms for the U.S. and its allied partners.
Why This Matters
This expansion by HII holds significant implications across several critical domains, from national security and technological innovation to economic development and the future of maritime operations.
Firstly, from a **national security perspective**, the increased production capacity for systems like the U.S. Navy’s Lionfish UUV is a direct response to evolving geopolitical landscapes and strategic defense requirements. Uncrewed undersea vehicles are becoming indispensable assets for navies worldwide, offering capabilities for intelligence, surveillance, and reconnaissance (ISR), mine countermeasures (MCM), anti-submarine warfare (ASW), and even offensive operations, all while keeping human personnel out of harm’s way. The Lionfish, derived from a proven commercial design, represents an agile and cost-effective approach to fielding critical capabilities rapidly. The ability to produce more of these systems strengthens the U.S. Navy’s posture in crucial maritime theaters and provides an advantage in an era where naval power is increasingly defined by technological superiority and distributed lethality. Furthermore, the expansion supports allied nations, fostering interoperability and shared security objectives.
Secondly, the investment underscores **the accelerating pace of technological advancement** in autonomous systems. HII’s focus on developing sophisticated autonomy software, modeling, and simulation tools alongside hardware production signifies a holistic approach to unmanned system development. This integration of advanced artificial intelligence and robotics is not merely about building vehicles; it’s about creating intelligent, interoperable networks that can execute complex missions with minimal human oversight. The Odyssey Autonomous Control Solutions are critical for enabling multi-vehicle missions and adaptive decision-making, pushing the boundaries of what is possible in autonomous maritime operations. These innovations will likely trickle down to commercial and scientific applications, benefiting broader ocean industries.
Thirdly, the expansion has a tangible **economic impact**, particularly for the state of Massachusetts. The addition of 10,000 square feet of manufacturing space and the creation of approximately 50 new jobs (with 300 already employed) represent a significant investment in advanced manufacturing and skilled labor. This supports local economies by providing high-quality employment opportunities in a cutting-edge technological sector. HII’s continued growth in the region also reinforces Massachusetts’ reputation as a hub for robotics, defense technology, and oceanographic innovation, partly due to its long-standing collaboration with institutions like Woods Hole Oceanographic Institution. This synergy between industry and research fosters a robust ecosystem for further technological breakthroughs.
Finally, this development signals a clear direction for **the future of maritime operations**. The global trend is towards increasingly autonomous and distributed naval forces, where uncrewed platforms augment and, in some cases, replace traditional crewed vessels. This not only enhances capabilities but also promises greater efficiency, reduced operational costs, and lower risk to human life. HII’s expansion positions it at the forefront of this transformation, ensuring the continuous supply of critical autonomous systems that will define naval power and ocean exploration for decades to come. The continued reliability of the REMUS family, with over 90% remaining in service after 25 years, also highlights the long-term viability and impact of these technologies on naval strategies and scientific endeavors globally.
