Fusō was the lead ship among two Fusō class dreadnought battleships built for the Imperial Japanese Navy. She was launched in 1914 and commissioned in 1915. She had a displacement of 29,800 tons, length of 673 ft (205.13 m).
Fusō patrolled off the Chinese coast during WWI and in 1923, assisted the survivors of Great Kantō earthquake which had a magnitude of 7.9. She was modernized twice before WWII. With only 14-inch guns, she was outclassed by other Japanese battleships at the beginning of World War II and played auxiliary roles for most of the war.
During the Battle of Surigao Strait in southern Philippines, she was hit by 2-3 American torpedoes on the starboard side and capsized slowly to starboard in the early hours of October 25, 1944.
The torpedo attacks were launched from US destroyers and torpedo hits caused an oil fire too.
Fusō sank within 40 minutes and among the few dozen of the crew member who escaped, only 10 survived to return to Japan.
