  The flange, produced using additive manufacturing techniques from copper-nickel material, is the first of its kind to be welded at a U.S. public shipyard. The effort reflects a broader push to integrate advanced manufacturing solutions into operational naval platforms. The initiative followed a directive to accelerate adoption of additive manufacturing across the submarine force,
