HII Puts Up to $900 Million Behind Robotic Welding and Sanding in HYPR Push

Huntington Ingalls Industries has announced long-term performance-based production agreements with GrayMatter Robotics and Path Robotics, committing up to $900 million in total shipbuilding work over seven years. The deal signals a significant shift in how the shipbuilder intends to source fabrication work — and how much of it will be done by adaptive automation rather than fixed tooling inside its own yards.

Path Robotics provides robotic welding technology, while GrayMatter Robotics offers robotic sanding systems. Both companies are part of the HYPR program, launched by Huntington Ingalls in April to accelerate advanced, adaptive automation in the fabrication of naval platforms.

Two stages, from qualification to production

The agreements are structured in two stages: a Navy-grade development stage and a delivery stage.

In the development stage, the companies will develop, validate, and qualify high-precision production techniques. These techniques will be applied across autonomous welding, grinding, blasting, painting, assembly, inspection, and other fabrication processes.

The agreements also establish a testing, qualification, and oversight process to ensure technologies meet U.S. Navy shipbuilding standards. In the delivery stage, HII will begin sourcing shipbuilding work from both companies — a notable model in which automation partners effectively become production suppliers.

"We are committed to making generational investments to develop new shipbuilding capability and to expand capacity."

— Eric Chewning, executive vice president of maritime systems and corporate strategy at HII

Welding that leaves the fixed cell

One example of the technology in play: Rove pairs Path Robotics' Obsidian physical AI model with a quadruped robot for autonomous welding beyond fixed cells. For shipbuilding — where large assemblies don't fit neatly inside a robotic cell — mobile, adaptive welding addresses a long-standing constraint of conventional automation.

"For years, we’ve believed physical AI could fundamentally change manufacturing."

— Andy Lonsberry, co-founder and CEO of Path Robotics

The outsourcing math

The automation agreements sit alongside a broader sourcing shift. In 2026, HII plans to outsource more than 2.5 million hours of shipbuilding work, a 30% increase from 2025. The performance-based structure of the agreements means funding flows only as milestones are met — a pragmatic hedge on technology that still has to prove itself at production scale.

For manufacturing engineers, the takeaway is clear: adaptive robotics is no longer a pilot-line experiment in naval fabrication. It's being written into seven-year production contracts with real money attached.
