ww2dbaseUnryu, the lead ship of her class of aircraft carriers, was built upon a lighter design of the Soryu-class fleet carriers. She was commissioned in Aug 1944 with Captain Konishi Kaname in command. On 17 Dec 1944, she left Kure, Japan with 30 Ohka special attack rocket craft onboard, bound for Manila in the Philippine Islands. On 19 Dec, she was attacked by US submarine USS Redfish, which fired four bow torpedoes at her, hitting Unryu once under the bridge at 1635 hours. Unryu and her destroyer escorts fired their guns in the direction where the torpedo originated. At 1650 hours, another torpedo struck Unryu on the starboard side, under the forward elevator. The Ohka aircraft and aviation fuel were ignited, starting a fire in the lower deck hangar. The order to abandon ship was given, but the ship sank within seven minutes. 1,241 officers and men were lost, including Kaname. The 147 survivors were picked up by destroyer Shigure, which brought them back to Sasebo, Japan on 22 Dec 1944.

Since online sources like combinedfleet.com & wikipedia note that the US sub Redfish 'bottomed out' at around 230 feet to sit out the Japanese destroyers vain attempts to sink her, is it safe to assume that Unryu sank in relatively shallow water? Or had Redfish moved far away from the sinking location before hitting bottom? In either case, has anyone located and/or surveyed the wreck of the Unryu? (I've found nothing online saying so...)

people who served in world war II and still living. When the government had soliders put on chemical treated suits and then sprayed with posionous gas. Is still suffering from this today. Please respond.
