Without Truman's second SoD Johnson and Truman himself opposing military spending on the Navy and Army as opposed to the Air Force does the USS United States, (sorry but they are going to have to change that name, we got away with once in 1797 because we as a nation did not have "class" names as a tradition but come on, in 1948 it would mean you had to come up with OTHER country names for the other five carriers to 'fit' the way naming works, it is almost as if the Navy was taunting the Administration into at most building "only one" carrier) continue or get still get canceled?
USS America, USS Columbia, USS President, USS Congress, USS Union . . . there's ways around it. You could name them after the Six Frigates, but I don't think public opinion would stand for a USS Old Constitution [IX-21]. Perhaps USS New Ironsides.
