Nimitz Carrier by a longshot.
It'd take some work to make an SSN shoot old torpedoes that haven't been used in 70 years...and even back then some of them were old.
The Nimitz just needs to change which aircraft are stored on board. They have cables...WW2 naval aircraft have hooks.
It'd take little work to convert a Nimitz to WW2 aircraft compared to changing an SSN.
