well, being part of these mods...

i would comment that it would be very unlikely to make a CV work on the royal navy, and possibly USN mod... here are my reasons.
A.it looks fun, but in reality there wasnt much to do on a carrier. reason being
(subpart a.) you cant program planes to take off from the decks of carriers, you dont see it happen in sh3, 4 or UBM, its just not programmed into the game.
B. even if you did get the planes to take off...all you have left to do is wait until they all got shot down or came back....
C.leaving the only fun part to be if you got all that working...the management of bombs, shooting down enemy planes, and other little things that carriers have to manage...

just my thoughts on the subject, i can be (and usually am) proven wrong
