A couple of corrections. CVB-43 keel wasn't laid in 1943, it was laid on 10 July 1944
. Of course the "USS CORAL SEA" name was applied after USS FDR was applied to CVB-42 in April 1945 (officially renamed in early May 1945) after the president's death.
It is quite possible that no name had been applied to CVB-43 prior to April 1945, about nine months into her construction. I find no mention of a name being assigned to CVB-43 prior to USS CORAL SEA. Recall that USS CORAL SEA was first assigned to CVE-57, which then was renamed to USS ANZIO on 15 September 1944, so it could be assigned to CVB-42, whose keel was laid on 1 December 1943. So you can see that CVB-42 "wasn't"
named until about nine months AFTER
she was laid down.
I can believe that the USN command (and maybe the White House) had a few candidate names in mind, but had not yet decided on which to use.
Yea I know, I mean what was it's name before it was the Coral Sea? The first Coral Sea Was renamed as USS Franklin D Roosevelt soon after it was launched, then the next ship in line was named the Coral Sea. The keel was laid in 1943 and it had to be named something before it was the Coral Sea but duck duck go as I might, all anybody talks about is how the first Coral Sea was renamed the FDR, not what the ship's name was before it became the Coral Sea. Must be a big state secret or something.
