Akagi and Kaga are completed with three superstructure landing decks, the only such carriers in the world to be designed that way. Game of Thrones Crown Green Bay Packers shirt. The Glorious British British carriers, Courageous and Furious, were originally converted from “large light cruisers”, each with two landing stages, but there was no evidence that the Japanese had copied the model. of the British. It is possible that this is a convergent evolution of measures to launch as many aircraft as possible. Akagi’s main deck is 190.2 meters long (624 ft 0 in); the middle floor, starting right in front of the pier, is only 15 meters (49 ft 3 in) long; and the lower floor is 55.02 meters (180 ft 6 in). The question posed about the convenience of the middle floor because it was so short, only some light-load aircraft could be used, even in an era when the aircraft was small and much lighter than World War II.  The upper flight deck is slightly tilted from the middle of the ship to the nose and to the tail to support the take-off and landing of low-power aircraft at the time.
