Well, the USN 7th Fleet is based in Japan currently.
Formed in WWII in Australia, it was Mac's delivery service and was a major contributor (and I think CO) of the Leyte Gulf battles. From what I can tell, the fleet was in charge of the Korean War fleet and had the surviving BBs cycle through.
CV7 was the USS Wasp, recently located in January-
USS BB-7 was the USS Illinois, a pre-Dreadnaught built in 1897 . . . and last until 1955 as a training ship. Where they training US navy personnel to chip rust?
