Armoured deck's too thin, otherwise I have no issues.

Why submerged torpedo tubes when you can't be going full speed and open the doors?
Also, use geared turbines, not direct-drive.

As for the torpedo tubes, the idea is that the fish are there for finishing off a target that's been either bombed or bombarded. I'm leery of having the oxygen bottles out on deck.

The basis of this ship is actually a RL U.S. Navy proposal (see the Squadron/Signal "Escort Carriers In Action" book); that's where the 24 aircraft number comes from.
Turbulence isn't as much as an issue with this one because it has a conventional island and also has a slightly angled deck - which is another part of the historical design, it might be noted.
I'll scan the picture from the book later after my allergies aren't making me quite as miserable...
