In the Battle of the Philippine Sea that was also called the Battle for the Marianas by the Japanese, the Imperial Japanese Navy lost three aircraft carriers within a period of thirty-six hours. These were the Taiho, Shokaku, and Hiyo. All three were victims of the same fateful combination of torpedo damage that set up massive vapor-induced explosions. Adequate reports exist for the Taiho and, to a smaller degree, for the Hiyo's loss. The analysis concerned itself with the third carrier mentioned, the veteran and famous Shokaku, torpedoed and sunk by U.S.S. Cavalla (SS-244) on June 19, 1944.
