HII (NYSE: HII) and HD Hyundai Heavy Industries (HHI) are advancing their strategic partnership through a pilot program to deploy additional intelligent mechanized welding equipment at HII's Ingalls Shipbuilding division. The initiative builds on Ingalls' existing automation and technology strategy and comes as U.S. shipyards face sustained pressure to expand capacity and throughput amid growing Navy fleet requirements and a persistent skilled-labor shortage in maritime fabrication trades.

The pilot represents a significant step in U.S.–Korea shipbuilding cooperation, as outlined in a 2025 memorandum of understanding (MOU) between the two companies. South Korea is one of the world's largest commercial shipbuilding nations, and U.S. defense policymakers have increasingly looked to allied shipbuilding partnerships as a mechanism to strengthen the domestic industrial base. The HII–HHI collaboration also reinforces HII's commitment to innovating its operations as it delivers ships to the U.S. Navy.

"Ingalls operates one of the most advanced automated production lines in the U.S. shipbuilding industrial base," said Ingalls Shipbuilding President Brian Blanchette. "Investments in technology and automation range from large-scale automated panel lines and material handling, to robotic bulkhead fabrication, to numerous other digital and advanced manufacturing tools. This pilot extends that automation footprint further into the production process, and to a greater share of the workforce. Working with HHI allows us to expand targeted automation functions, and integrate shared best practices as we continue delivering the most capable ships to the U.S. Navy."

The pilot deploys intelligent mechanized welding systems in unit-fabrication areas that currently rely predominantly on manual welding. Welding is among the most demanding processes in shipbuilding, and these systems are designed to make it safer and more efficient. The equipment automatically recognizes workpieces and welding conditions, corrects welding positions in real time, and captures process data that can support quality control, process improvement, and traceability. Ingalls has confirmed that the machines comply with existing U.S. Navy fabrication standards and will use the pilot to identify opportunities for improved efficiency.

"This pilot program reflects the strengthening of our partnership and the advantages of open technical collaboration," said Dr. Won-ho Joo, chief executive of the Naval & Special Ship Business Unit at HHI. "We look forward to working with HII to enhance shipbuilding efficiency and deliver greater value to our customers."

The intelligent mechanized welding pilot originated from a three-day technical exchange at Ingalls, during which the two companies evaluated shipbuilding technologies and automation opportunities across their respective shipyards. During the visit, Ingalls showcased its hybrid laser welding process, robotics integration, and facility layout designed to support streamlined construction.

Additional automation and technology initiatives currently under evaluation or implementation at HII's shipyards — Ingalls Shipbuilding in Mississippi and Newport News Shipbuilding in Virginia — include new robotic and cobot applications such as fabrication cells, additive manufacturing, automated steel processing systems, integrated production control software that supports precise construction and real-time production insights, and continuous upgrades to automated panel and bulkhead lines.

HII's recently announced High-Yield Production Robotics (HYPR) initiative further teams the company with emerging physical AI technology firms to implement AI-enabled tools designed to augment the capabilities of the existing shipbuilding workforce.
