@Cmdr:
Screw dat. They wanna call it a carrier vehicle, fine, but I’m calling it an Aircraft Carrier or A.C. Not really sure what it’s an SS for Submarine either, shouldn’t it just be S? Same for Destroyer? BB makes sense, Battle Boat…close enough to Battleship afai-concerned.
It’s US naval ship class designation, and AC stands for auxilliary-collier. Any ship starting with “A” indicates auxilliary, I believe.
There’s no reason to call a carrier CA since it’s an unclear abbreviation, and if you call it AC most people will probably still understand what you mean , but since there is an official abbreviation that most people with knowledge of ww2 history will use, well, arguably it makes sense to keep them in mind or clearly spell out the ship rather than making abbreviations that have no historic significance (when there are already abbreviations with precedence).
