GrayMatter Robotics partners with Huntington Ingalls to bring physical AI to US shipbuilding

Summary

GrayMatter Robotics is announcing a partnership with Huntington Ingalls Industries, America's largest military shipbuilder and the company behind the Navy's aircraft carriers, submarines, and advanced surface vessels.

The problem Ariyan Kabir is solving is straightforward and large: US shipbuilding is running roughly 5 million man-hours short of what it needs. The industrial base that built ships at scale during World War II has hollowed out, and demand from the Navy — including a new generation of unmanned surface and subsurface vessels — is accelerating faster than the workforce can.

What GrayMatter actually builds

GrayMatter deploys autonomous robot cells that handle the labor-intensive surface processes in manufacturing — sanding, grinding, painting, coating, blasting, inspection. The company is hardware-agnostic, embedding its physical AI into whatever form factor fits the job: six-axis arms fixed to a floor, robots on rails that travel along a submarine hull, or mobile-base systems. The structures it works on range from military helmets to fighter jets to submarine components.

Kabir founded the company roughly six years ago, when the robotics field was almost entirely focused on autonomous vehicles or logistics pick-and-place. Manufacturing — where he says roughly 90% of factory operations are still done manually — was largely ignored.

The pitch goes beyond robot arms. Kabir argues that unlocking factory capacity requires AI agents layered across the full engineering stack: industrial engineering, process engineering, materials science, and maintenance operations. Autonomous robots handle the physical processes; domain-specific AI agents handle the surrounding engineering decisions. Without both, he argues, the throughput gains stay marginal.

The HII partnership

The scope of the Huntington Ingalls deal isn't detailed in the announcement beyond the strategic framing. HII is the right anchor partner for the thesis — it builds the Navy's most complex vessels and is already working on next-generation unmanned systems alongside new primes like Anduril and Sarcos, as well as established contractors like Lockheed. Plugging autonomous manufacturing capacity into that pipeline is the commercial logic.

Kabir frames this as a national security moment, not just a commercial one. The gap between what the Navy needs to build and what the current industrial base can produce is the opening. GrayMatter's bet is that physical AI closes it faster than hiring alone ever could.
