2 second overhead shots of the American or  Japanese carrier groups traveling they show a modern United States  Nimitz Class nuclear aircraft carrier. These modern carriers look  absolutely nothing like the shorter and narrower WWII carriers. What  is most obvious is the angled flight deck of the modern carriers  which did not come into existence until after the war. Sometimes  they do get the carriers right, like when they take off for the  Dolittle Raid you can see the correct deck plan of the WWII USS  Hornet.
