German carrier looks somewhat like Graf Zepellin, although I don't think it's very accurate. British one does a good impression of Ark Royal. American is either Lexington-class or Yorktown-class. Soviet one is obviously fantasy, since USSR had no carriers in WW2 period, but it looks quite like how one could picture oneself a Soviet carrier.
German and Soviet ones use destroyer animations, British and American use carrier animations.
