Talking about a packed/jammed deck... these older classes had no below deck hangar ?
Most if not all of them do including the IJN fleet carriers of WWII.
As we all know as well, a few of the American WWII carriers served well into the 1970s and 1980s through major refit and modifications. If would have been quite impossible to put a hanger in there if it wasn't design originally like that.
