How HII Is Integrating Physical AI Into Shipbuilding — and What It Means for American Naval Dominance

Even though the hulls are huge, the first thing you notice when you walk into a shipyard in Pascagoula or Newport News on any given morning is not their size. It’s the sound. The sound of grinders screaming against steel, the humid air filled with the smell of welding flux, and the low thump of cranes moving plates. This has been the sound of American shipbuilding for over a century. What’s holding the grinder is changing, first gradually and then abruptly.

HelloI’ve been signing partnerships with AI companies for the past few months, and it’s getting harder to ignore the trend. In April, I used intuition. GrayMatter Robotics by the same window. Path Robotics in February. Three transactions, three distinct aspects of the issue, all pointing in the same direction. The company appears to be placing a wager that the speed at which software and robots can be integrated into yards that have operated essentially in the same manner since the Cold War will determine the next era of naval dominance rather than just displacement tonnage or missile tubes.

The public face of the majority of these announcements has been Eric Chewning, who oversees corporate strategy and maritime systems. He discussed a “American shipbuilding renaissance” at the GrayMatter signing, which is the kind of phrase executives use to sound upbeat without committing to a figure. However, the figures are located beneath. In 2025, throughput increased by 14%. a 15% goal for 2026. In a sector where it can take ten years to add a single dry dock, those aren’t soft goals.

The most concrete is the GrayMatter piece. Their robots perform the unglamorous tasks that have always been difficult to staff, such as sanding, grinding, blasting, and coating. These tasks wear out human bodies. If the company’s claims of a 95% decrease in rework and a 12x increase in skilled labor throughput hold true at scale inside a Navy yard, it would be impressive. If you’re climbing around the curved hull of a destroyer instead of a spotless factory floor in Carson, California, those figures might appear different. Seldom do industrial demos endure contact with reality unaltered. Nevertheless, the path is obvious.

Applied intuition, on the other hand, is a completely different animal. The $15 billion company, which is led by a co-founder with experience in autonomous vehicles, is proposing Warship OS, which is essentially an operating system for ships. Beginning with HII’s ROMULUS unmanned surface vehicles being constructed down in Louisiana, the goal is to integrate data and autonomy throughout an entire vessel. The idea is to move it onto crewed platforms after it succeeds on the unmanned side. For that part, Ingalls is being scheduled.

As this develops, it seems like HII is reacting to more than just a market opportunity. The disparity in China’s ability to produce military and commercial ships has become a persistent source of concern in Washington. On labor alone, American yards cannot surpass Chinese yards in volume. The math could be made to work, or at least less detrimental, through software, autonomy, and physical AI.

It’s unclear if any of it truly results in quicker Navy deliveries. Ambitious timelines have a tendency to be humbled by shipbuilding. However, it’s difficult to ignore the fact that industry discourse has changed, virtually without anyone noticing. The smell of welding flux is still present in the yards. The grinders continue to scream. Simply put, fewer and fewer people are holding them.
