The IJN Katsuragi was an Unryu-class aircraft carrier of the Imperial Japanese Navy that served in World War II.
In 1944, the Katsuragi along with the Unryu and the Kasagi took part in the Battle of the South China Sea. Katsuragi had survived the initial strike by Allied airwings however it was soon attacked again afterwards when HNLMS Zeehond fired her remaining torpedoes at near maximum range. While only a single torpedo hit, but it not only obliterated her starboard driveshafts and killed several boilers in the process, but it also warped the other ones, causing more leaks that led to the ship rapidly sinking by the stern.[1]
