Kongō is a Kongō-class fast battleship constructed in Britain at Vickers Shipbuilding Company, Barrow-in-Furness. Her design utilized Western naval technology, making her the final Japanese capital ship built abroad. Commissioned in 1913, she underwent major reconstructions in 1929 and 1935, transitioning from a battlecruiser to a fast battleship capable of keeping pace with carrier fleets. She fought in significant Pacific War engagements: covering landings in British Malaya and the Dutch East Indies, the Battle of Midway, the Guadalcanal Campaign, the Battle of the Philippine Sea, and the Battle of Leyte Gulf. Her service concluded when torpedoed and sunk by the submarine USS Sealion in the Formosa Strait on November 21, 1944, marking her as the sole Japanese battleship sunk by submarine in World War II.
In official adaptations, Kongō exhibits a highly energetic and expressive personality, frequently interjecting English phrases. She demonstrates intense devotion to the Admiral, constantly expressing concern for their well-being and reacting possessively to potential distractions. She acts as a supportive leader for other shipgirls, especially destroyers, whom she addresses with nicknames. In combat, she adopts a confident demeanor, using phrases like "Burning... Love!" during attacks and showing tactical awareness in fleet coordination. Her interactions reveal a preference for black tea, reflecting her British origins.
Kongō possesses high firepower, armor, and speed, classified as a Fast Battleship. Her resource consumption is lower than other battleship classes, enhancing operational efficiency. She progresses through multiple remodels:
- Kongō Kai at Level 25 improves base stats and equipment slots.
- Kongō Kai Ni at Level 75 further enhances combat capabilities and grants a special Anti-Air Cut-In ability shared with Royal Navy ships.
- Kongō Kai Ni C at Level 92 sacrifices some armor for torpedo capabilities and seaplane fighter deployment. This remodel also enables a "Night Assault" special attack when flagship, requiring a specific helper ship and fleet composition. The attack involves sequential strikes with accuracy modifiers and consumes extra ammunition.
Her equipment compatibility includes bonuses for specific guns like the 35.6cm Twin Gun Mount Kai and torpedo mounts, but she suffers accuracy penalties with 41cm or larger guns. She wears a sarashi when moderately damaged; her damaged art depicts torn clothing and distressed expressions, emphasizing vulnerability during repairs. Merchandise reflects these traits, including figures in damaged states and graphic T-shirts featuring her design.
In fleet operations, she emphasizes unit cohesion with lines like "Follow me!" during deployment. Her quotes reference post-battle aspirations, such as sharing tea with the Admiral. She exhibits situational awareness, cautioning about appropriate conduct during idle moments and reacting sharply to mail notifications. Her library entry highlights her intent to leverage high speed for effectiveness in Pacific operations.
