IJN Battleship Design A-122

Design A-122 was the largest and heaviest among the fast series of 32knots preliminary variants of the Tosa/Kaga havign reaching more then 280m in length and 43.000+tons of displacement! Armour wise it continues the same layout begun with the first post-Nagato design of A-115. Based on the stats and available info this proposal might be the fast version of A-120 showing how much engine power (extra 33.000shp) and waterline length (extra 23meters) required to propel a ship from 56 to 59km/h!
With armament remains unchanged the extra length allows wide placement of the secondary casemated guns in the 1st deck.

The sheer size of the design clearly illustrates the requirements for high speed: Long sleek hull with large engine power

The design had the following characteristics:
Dimensions: 266,7 (pp) x 281 (wl) x 282,85 (oa) x 29,57 x 9,14 meters
Displacement: 43.500tons (standard)
Armour: 229mm Belt inclined at 25 degrees, 76mm Deck, 51mm at Machinery 76mm at Magazine Slopes
Engines: 157.000shp Gihon Steam Turbines, 4 shafts
Range: 10.200km at 30km/h (5.500nm at 16knots)
Speed: 59km/h (32knots)
Armaments:
5x2 410mm/45 Type 3 / 3rd Year Type Cannons,
20x1 140mm/50 Type 3 / 3rd Year Type Guns,
4x1 76mm/40 Type 3 / 3rd Year Type AA Guns,
