Hard to imagine the manufacturing, and building might we had back then. I recall watching a documentary on the recovery efforts on Pearl Harbor. One of the smaller destroyers was missing the front third. They raised her, fitted a temporary bow, and sailed her back to California, who had her repaired and back sailing by June After training, she was back in Perl Harbor by August 1942. She served throughout all the remainder of WWII.
USS Shaw.
Mind boggling when you look up how many ships, tanks, planes, trucks, guns, ammo, tents, and everything else we made in a few years.
