US Aircraft Carriers carry the designation CV, with a number. What do the letters CV stand for?
	
		
	
	
		
		
			cruiser voler - the last word is French meaning heavier than air flying (i.e., planes)
		
		
	 
I think I'll give you that one.  Yes, the C stands for cruiser - cos the early carriers were cruiser-sized (not converted cruisers, usually).  The V comes from the english word aViation - which is near enough to the french word voler to win you the prize.
The letters-plus-numbers designations of US warships were originally introduced because ships names are not (quite) unique.  The navy was already using CA as a designation for another class of cruisers.
