Izumo and the A-140 J2 design tradeoffs

What are the advantages and disadvantages of the Japanese A-140 J2 preliminary Yamato design represented as Izumo in World of Warships?

The forward battery permits a compact ship and narrow end-on target. The real proposal's stated 29-knot target is distinct from the game's 27.2-knot base speed and 28-knot engine upgrade.

World of Warships uses Izumo to represent the real A-140 J2 preliminary Yamato design. The discussion distinguishes the game's turret arrangement from an alternative with all three turrets facing forward. Concentrating the battery permits a more compact ship and a narrow end-on target while retaining heavy forward fire, fitting the described Japanese aim of damaging an opponent at long range and withdrawing. The game's 27.2-knot base speed rises to 28 knots with its engine upgrade, while the historical proposal is described as intended for 29 knots. Clarke uses 28 knots as the fast-battleship threshold because it allows contact with the cruiser line. The proposed machinery combines steam turbines and diesel engines. Its standard displacement is described as 16,000 tons below Yamato's.
