Much of the criticism of Shinano’s design is predicated not on the ship’s battle history—the carrier participated in only one, lopsided “battle”—but in how the carrier support ship design would have fared given what we know about the Pacific War. Shinano would be fitted out as a 68,000-ton aircraft carrier similar in construction to the smaller Taiho. Their AA varied during their service, between six and eight 127 mm and six 120 mm for Taiyo, with initially eight 25 mm, then 24 on Taiyo and Unyo, and 22 plus 5 heavy 13 mm machine guns for … Key point: The Shinano was supposed to be a battleship but was poorly rushed into a makeshift carrier instead.
