Summary
- HII and GrayMatter Robotics signed an MOU on April 6, 2026 to explore physical AI in shipbuilding.
- The first target areas are surface preparation, coating, inspection, workforce training, and unmanned system production support.
- For welding readers, this matters because it sits around the weld line, while HII’s February 2026 Path Robotics deal was the one centered on autonomous welding.
HII, the largest shipbuilder in the US, has teamed up with GrayMatter Robotics to explore how physical AI can be used in shipbuilding. The companies signed a memorandum of understanding to study ways to raise throughput, support the maritime industrial base, and add automation without removing the importance of skilled workers. Financial details were not disclosed.
The GrayMatter side of the deal is not mainly about the weld itself. It is focused on the jobs around fabrication and finishing: surface preparation, coating, and inspection. In the official demonstration, the technology was shown in sanding, grinding, blasting, coating, and inspection work, with HII saying the goal is to handle high-mix, high-variability shipyard production with more speed and consistency.
For welding people, that is the real angle here. Welding automation usually gets the spotlight, but a lot of time is also lost after welding, in grinding, cleaning, coating prep, and quality checks. HII says its shipbuilding throughput rose 14% in 2025 and it wants another 15% increase in 2026.

This GrayMatter deal follows HII’s February agreement with Path Robotics, which was focused on autonomous welding, so the company now seems to be building automation on both the welding side and the post-weld side.
