HII signs deal with Path Robotics on AI welding for manned and unmanned shipbuilding
American defense giant HII and Path Robotics have signed a memorandum of understanding (MOU) to explore the integration of Path’s physical artificial intelligence (AI) for welding into shipbuilding operations.
The MOU signing ceremony took place at Path Robotics’ headquarters and was attended by Eric Chewning, HII’s executive vice president of maritime systems and corporate strategy, and Andy Lonsberry, Path Robotics CEO and co-founder.
HII and Path Robotics will work to identify and potentially pursue future opportunities in three areas that include autonomous shipbuilding capability development, train a workforce to extend automation and establish an intellectual property framework for physical AI-based autonomous welding systems.
In addition, the companies will pursue research and development around integrating Path’s physical AI models with other innovative shipbuilding technologies used in the construction of HII ships, to include HII’s ROMULUS line of unmanned surface vehicles.
Together, these technologies would augment the welding workforce, automate structural production, and accelerate throughput to advance national security objectives.
Path’s physical AI model for welding, Obsidian, and proprietary sensing and vision system transforms a traditional industrial robot arm from a rigid, repeat-only machine into a real-time perception and decision-making system that can see, understand, and adapt to the variations of a shipbuilding environment.
“We are excited to partner with Path Robotics to incorporate their state-of-the-art physical AI models to further augment our workforce and speed up U.S. Navy manned and unmanned shipbuilding production,” Chewning said.
“Our shipbuilding throughput was up 14% in 2025 and we are looking for an additional 15% increase in 2026. By working with new partners like Path Robotics, we can further accelerate shipbuilding production.”
“Welding is one of the hardest processes to automate in any industry, and shipbuilding is no exception. Path’s physical AI is purpose-built for that challenge – seeing, understanding, and adapting to real world conditions in real time. We’re honored to work alongside HII to help modernize defense manufacturing and strengthen the naval industrial base for decades to come,” Lonsberry commented.
Prior to the MOU signing ceremony, attendees from HII, local dignitaries and Path stakeholders walked the Path Robotics factory floor and observed robotic welding demonstrations in the company’s new intelligence center.
The demonstrations showcased how Path Robotics systems may be applicable to naval fabrication work, ranging from heavy foundations to large, complex ship structural assemblies. The technology showed how an autonomous welding system can adapt to unpredictable shipyard conditions, such as fit variations, complex joint types, and different materials.
Currently, HII shipbuilders perform specialized, high-tolerance welding and direct weld support activities on large, complex ship structures without an AI-based autonomous welding capability. HII divisions use automated robot welders that require human collaboration; they are traditional panel line units, cobot welders that work alongside shipbuilders.
