I think Bulgaria is already heading down the right path by ordering several CL's which could protect supply lines to Russia. A floatplane cruiser might be possible though, an Ankara type with floatplane facility's aft instead of a third triple turret.

Contribution to an allied fleet? im not to sure on the why, I can give all the why nots. Example you are fighting Russia, your fleet is basicly Hosed anyway BB CVL CL DD dosnt realy matter they have more. (Basicly the same situation im in with Italy) anyone realy has to come to you bringing them in range of land based aircraft, and small fast ships.
My plan was for more of a Hybrid.

Im going to pursue a light carrier in1945 however until then my naval build plans are to replace my old austrian CLs, as well as replace my old destroyers, and build some submarines. Should Russia decide to build a cruiser killer, I shall probably respond with a small BC (around 25000) 12 in guns. Also, the dive/torpedo bombers are for land based squadrons, not for use on carriers.
