NEWPORT NEWS, Va., March 04, 2025 (GLOBE NEWSWIRE) -- HII (NYSE: HII) announced today that shipbuilders at its Newport News Shipbuilding division have successfully installed the first valve manifold assembly created by additive manufacturing technology on a new construction aircraft carrier. NNS continues to integrate additive manufacturing, also known as 3D printing, into the shipbuilding process. The use of certified 3D-printed parts has the potential to accelerate construction and delivery of vessels to the U.S. Navy by cutting lead times and improving manufacturing quality for critical components. The valve manifold assembly, a specialized assembly that allows distribution of a single source of fluid to multiple points on the ship, is installed in a pump room on Gerald R. Ford-class aircraft carrier Enterprise (CVN 80). The assembly, which is approximately 5 feet long and 1,000 pounds, reflects the shipyard’s pursuit of all opportunities to support construction using additive manufacturing. NNS collaborated with DM3D Technology to manufacture the manifold body. With the completion of this evolution on Enterprise (CVN 80), similar manifolds planned for Doris Miller (CVN 81) will employ additive manufacturing rather than traditional casting methods, reducing schedule risk and improving efficiency.

To date, the shipyard has created more than 55 additively manufactured parts installed on both new construction vessels and those currently in the fleet, with plans to install more than 200 additional parts this year.
