What really stands out on that list of US subs sunk is the tiny percentage lost to aircraft. Contrast that with the HUGE contribution planes made to sinking U-Boats in the Atlantic. Close to 50% lost due to aircraft. Some of that is due to US subs having air search radar. But aircraft could have been instrumental in keeping subs kept down and submerged until convoys and ships could have passed. The Japanese really fell down on the job in this area. They had some of the best long-range patrol planes in the world with the Kawanashi (Emily and Mavis) flying boats. The had escort carriers too. But mainly used them for ferrying planes and training.
