This is yet another design of the Amagi class carrier conversion proposals and one of the most unique ones with it's large armoured funnel casing blending outward from the flight deck. Still you can see many aspects which were integrated into the final Akagi the aft positions of the casemates finalised, one single large outward angled funnel, final number of 6x 12cm AA guns per side and flight deck size closing that of the final design.
The design had the following characteristics:
Dimensions: 235 (pp) 248 (wl) 268,5m (oa) x 38 (at sponsons and funnel) x 6,58m
Displacement: 29.600tons (standard), 33.000tons (full load)
Armour: 127mm Belt, 79mm Deck
Engines: 131.200shp, Gihon steam turbines, 4 shafts
Range: 14.800km at 26km/h (8.000nm at 14knots)
Speed: 57km/h (31,75knots)
Armaments:
10x1 20cm/50 Type 3 (3rd Year Type No.1) Casemated Guns
6x1 12cm/45 Type 10 (10th Year Type) Casemated Guns
12x1 12cm/45 Type 10 (10th Year Type) AA Guns
Aircraft capacity: 36-40 planes (probably)
