      From the article

      >Curtiss-Wright’s EMS Division delivered the first submarine component with an additively manufactured (AM) impeller that will be installed in a U.S. Navy vessel. [Sintavia, a specialist in designing and manufacturing critical additively manufactured defense components](https://www.voxelmatters.directory/company/sintavia/), provided the AM impeller after a thorough qualification process.

      >“Sintavia has proven to be an invaluable industry partner, and we are excited about the opportunity to further solidify our partnership by increasing the number of additively manufactured parts for this application and other critical naval defense components,” said David Micha, Sr. Vice President and General Manager of the EMS Division. “In addition, we are proud to be providing the first critical service equipment utilizing an additively manufactured component to the U.S. Navy’s submarine program and look forward to expanding these capabilities in the future to more efficiently serve our customer.”

      >Curtiss-Wright’s Engineered Pump Division (EPD) in Bethlehem, PA, Bechtel Plant Machinery Inc. (BPMI) in Monroeville, PA, and Sintavia, LLC in Fort Lauderdale, FL, collaborated to develop, manufacture, test, and supply the first submarine component utilizing a qualified, metal additively manufactured part. This impeller was assembled into the pump and tested at Curtiss-Wright’s facility in Bethlehem, PA.

      I’m not sure about the title here, the article has a lot more adjectives when calling out “firsts”. It’s the first qualified additively manufactured metal component used on a submarine, which would imply qualified additively manufactured metal components have been used elsewhere in the fleet. It’s also saying this is the first impeller with 3D printed parts, which is just one subsystem.

      In summary, this is a cool development but probably not the first 3D printed part used on a Navy ship.
