Haruna was a warship of the Imperial Japanese Navy during World War I and World War II. Designed by the British naval engineer George Thurston, she was a battlecruiser of the Kongō class, among the most heavily armed ships in any navy when built. Named after Mount Haruna, she was laid down in 1912 and commissioned in 1915. Beginning in 1926, she was rebuilt as a battleship, strengthening her armor and improving her speed and power. In 1933, her superstructure was completely rebuilt, her speed was increased, and she was equipped with launch catapults for floatplanes. Now fast enough to accompany Japan's growing carrier fleet, Haruna was reclassified as a fast battleship. During the Second Sino-Japanese War, Haruna transported Japanese troops to mainland China. On the eve of the Japanese attack on Pearl Harbor, she sailed as part of the Southern Force in preparation for the Battle of Singapore. Haruna fought in almost every major naval action of the Pacific Theater, including the Battle of Midway, the Guadalcanal Campaign, the Battle of the Philippine Sea and the Battle of Leyte Gulf. In 1945, Haruna was transferred to Kure Naval Base, where she was sunk by aircraft of Task Force 38. (Full article...)
