IJN Battleship Design A-119

A-119 was a unique design in the post Nagato series. The official drawing I've linked shows the 14 underwater torpedo tubes an extremely strong torpedo armament for a capital ship but as you can see the design number 119 was looks like erased or ruled over. The next drawing A-120 depicts the same drawing with same dimensions just 1.000tons heavier and 4.000shp more engine power but without the underwater torpedo tubes. The A-120 drawing clearly shows the erased parts of A-119. Also the data tables in the Hiraga archive all states 4 above water 53cm torpedo tubes and different dimensions! So I've created two versions, this original A-119 which is exactly same above water as A-120 (minus the torpedo tubes) and the modified smaller version with above water torpedo tubes.

The design had the following characteristics:
Dimensions: 243,84 (pp) x 260 (oa) x 29,57 x 9,14 meters
Displacement: 39.400tons (standard)
Armour: 229mm Belt inclined at 25 degrees, 76mm Deck, 51mm at Machinery 76mm at Magazine Slopes
Engines: 120.000shp Gihon Steam Turbines, 4 shafts
Range: 10.200km at 30km/h (5.500nm at 16knots)
Speed: 56km/h (30knots)
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,
14x1 53cm Underwater Torpedo Tubes

As the data in the Hiraga Archive not entirely clear about this proposal (Having a drawing with different data then the data tables)
I've made both versions. While the drawing version shows 14 underwater torpedo tubes, this modified version was smaller (some 3meters shorter) and displaced 1.000tons less, 38.400 rather 39.400 but the engine power and speed remained the same. It is possible that the 14 torpedo version was Yuzuru Hiraga's private own proposal or maybe a mis interpretation for a requirement set on one of the meetings of the Admiralty. As a sidenote the A-119 proposal seems to be the very first design to incorporate 5 twin turrets of the 41cm cannons introduced on the Nagato class and what essentially became the standard for all subsequent designs:
good speed, long sleek hull, 3 turrets aft 2 forward, 41cm main armament, 4 AA guns. until the later No.13 designs and their 46cm weaponry.

The modified design had the following characteristics:
Dimensions: 240,79 (pp) x 256,95 (oa) x 29,57 x 8,76 meters
Displacement: 38.400tons (standard)
Armour: 229mm Belt inclined at 25 degrees, 76mm Deck, 51mm at Machinery 76mm at Magazine Slopes
Engines: 120.000shp Gihon Steam Turbines, 4 shafts
Range: 10.200km at 30km/h (5.500nm at 16knots)
Speed: 56km/h (30knots)
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,
4x1 53cm Above Water Torpedo Tubes
