Every Navy had seaplane tenders, and from those tenders operated all type's of seaplanes, also seaplane bases were built in and around loggons and sheltered coastal areas, as well as coastal air bases. In Ah this could mean, Port's, CV groops, and coastal Airbases, as well as coastal V bases.
Another point is look at the back of the CA in the standard MA fleat. their is a Float plane launcher promentaly modeled, while it certainly would not suport and Emily, I can think of A bunch of cool planes it would. So the CV is sunk u can still up a AR 196, or a Jake:)
