...approximately 20,000 pounds of steel, from CVN-65, has been salvaged and recycled for inclusion into CVN-80, with another 15,000 pounds still to be processed, for a total of 35,000 pounds. Enterprise will also incorporate four portholes taken from CV-6, her World War II predecessor. Also, an anchor from CV-65 went to the USS George Washington.While not mechanical parts, I believe the new CVN-80 Enterprise uses some metal recycled from the CVN-65 Enterprise.
