History:

Nagato (Japanese: 長門, named after Nagato province) was a battleship of the Imperial Japanese Navy, the lead ship of her class. She was the first battleship in the world to mount 16 inch class (actually 16.1 inch, or 410 mm) guns, and her armour protection and speed made her one of the most powerful capital ships at the time of her commissioning.

She was the flagship of Admiral Isoroku Yamamoto during the attack on Pearl Harbor. In the war she saw action only once, during the Battle of Leyte Gulf, due to the Japanese Navy's strategy of keeping major units in reserve for a decisive battle.
