In electing to focus on propulsion and speed, weight had to be saved from the armoring. Ergo, the Japanese opted to implement the “all-or-nothing” armor principle that was championed by the US; maximal armor to the vital areas whist non-critical surfaces receives minimal armor. The main belt and the barbette rings received 12 inches of armor, whilst the conning tower and the turret faces received 14 inches and 18 inches of armor, respectively. While this was sufficient to rival other battleships of the period, British and US battleships all had heavier armor, with belt armors exceeding 13 inches for many classes. | In electing to focus on propulsion and speed, weight had to be saved from the armoring.

? | After experimentation with the six turret design of the ''[[Fuso]]'' class, Hiraga and his designers decided to revert back to a quadruple turret design, determining this configuration to be the most effective. In order to not decrease overall firepower — by reducing the number of barrels from 12 to 8 — the caliber each rifle was increased from the traditional 14 inches to 16 inches; in fact, the ''Nagato''-class battleships were the first ships in the world to mount 16-inch naval rifles. To supplement the primary artillery, twenty (20) 5.5-inch casemate guns were added to the hull. Interestingly, the ''Nagato''-class retained the Japanese tradition of fitting torpedo tubes to their battleships. Historically, eight (8) total tubes were incorporated in the design; 4 above the waterline and 4 submerged (only the four above the waterline are available in-game). | + | After experimentation with the six turret design of the ''[[Fuso]]'' and ''Ise'' class, Hiraga and his designers decided to revert back to a quadruple turret design, determining this configuration to be the most effective.

? | The ''Nagato''-class underwent a modernization in the late 1920s and a reconstruction in the 1930s to keep the designs combat-capable. During the 1920s modernization, the first funnel was replaced with a serpentine funnel with a raked-top in order to attempt to fix the issue of the superstructure being occluded with smoke; the very funnel seen in-game.

Unique to ''Mutsu'', her bow was remodelled in order to decrease water spray to her foredeck. The 1930s reconstruction proved to be a more extensive overhaul. The iconic 7-masted superstructure was replaced with a pagoda-mast style design, and the first funnel was removed altogether. The old boilers were replaced; the overall number was also reduced to just ten (10). Interestingly, the old turrets were replaced by the ones of the incomplete "Tosa" class battleships, allowing for greater gun elevation, ergo greater range. Furthermore, torpedo bulges were introduced. To mitigate the loss in ship speed due to the added weight, the length of the battleships were increased. Finally, a catapult was added to launch scout planes off the deck. | |

Mutsu — Japanese special premium Tier VI battleship.
A Nagato-class battleship designed using experience gained in World War I to become one of the first "high-speed" battleships. The ship's armor protection was very good for her time. In addition to her primary armament, she also carried torpedo tubes.

Camouflage
As a premium ship, Mutsu comes included with Type 10 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, and increases the amount of experience she earns.
