Amagi Aircraft Carrier Preliminary Design 5

With this next preliminary design the Amagi/Akagi got closer to it's final form. By fixing the large ski like flight deck of the previous design by moving the flight deck higher supported by beams and other structural elements the the landing of aircraft became much more simple and potentially more safe. In the same time the entire bridge part together with the twin turrets moved forward and the flight deck extended aft resulting in even more flight deck space for the aircraft. Armament wise the only change was the introduction of the twin 12cm DP-AA guns in open mounts on the same places as before eg 2 under the forward flying off deck, and 2-2 at each sides after the funnel.
A more refined version of this design exists where the after part of the flight deck squared off, the aft part of the hull cut one deck level and the arrangement of the AA guns became symmetrical.
You clearly see how the final Akagi evolved from these two designs, using the space below the flight deck for hangers and re-arranging the inner hangers structure and layout the capacity for aircraft could be doubled! The make the flight deck free from obstacles and fumes the funnel was bent down and sideways though this resulted the fumes reaching the port side AA guns hence the creation of the first fully enclosed DP-AA mount for the IJN.

Range: 14.800km at 26km/h (8.000nm at 14knots)
Speed: 57km/h (31,75knots)
