Nagato

Nagato-Class Battleships (長門型戦艦) were built for the Imperial Japanese Navy during the years of 1917 to 1921. Nagato used the American "all or nothing" armor scheme that maximized the armor thickness protecting the core of the ship by eliminating armor elsewhere, As well as new underwater armor protection to protect from torpedoes. There were 2 of this class built.

Nagato-Class Battleships served between the years of 1920 to 1945

Tosa class (planned)

Yamato class (actual)

Nagato-Class Battleship Mutsu, assigned to the Support Force, fired four shells at enemy reconnaissance aircraft during what was her first, and only, action of the war on27 August, 1942. On 8 June 1943, Mutsu was moored at Hashirajima when the magazine of her No. 3 turret exploded at 12:13, cutting the ship in half. Nagato saw more action initially, escorted three aircraft carriers during the Battle of the Philippine Sea where she was only lightly engaged during the battle, was not damaged, and suffered no casualties. She took part in "Operation Sho-1", an attack on the Allied landings on Leyte. She was attacked by multiple waves of American dive bombers and fighters during the Battle of the Sibuyan Sea on 24 October en route to Leyte Gulf. She was struck twice by bombs but was not seriously damaged. The next morning, they attacked the American forces supporting the invasion in the Battle off Samar. Nagato engaged the escort carriers and destroyers of "Taffy 3". She opened fire on three escort carriers, the first time she had fired her guns at an enemy ship, but missed. One of the defending destroyers fired a spread of torpedoes that missed their intended target and headed for Yamato and Nagato which were on a parallel course. The two battleships were forced to turn away north to avoid the torpedoes, and were 10 miles (16 km) away from the engagement before the torpedoes ran out of fuel. Turning back, Nagato engaged the American ships, claiming damage to one cruiser. Later in the day, Nagato was hit in the bow by two bombs, but the damage was not severe.  Upon her return home a lack of fuel and materials meant that she could not be brought back into service and she was turned into a floating anti-aircraft battery.
