You mean the Canberra class that can't take F35? At least not without some costly mods.
This has been done to death elsewhere. If you're going to do carrier strike you get a deck big enough to do it. Or you don't do carrier strike.
Little decks are comforting for some, because they think they're cheaper or somehow less demanding on resource. What you actually end up with is something that looks ok on paper, but is of very limited use for ops at scale.
Ocean herself is knackered - although less to do with the hull and "commercial standards" than the marine systems, many of which were bought as end of production run items (therefore cheap), but unable to accept efficiency and environmental upgrades. Oh - and almost no ILS as well, which means that she is a nightmare to support.
