Sounds like a concerted search effort. "The wreckage of the U.S.S. Stewart, the only American destroyer captured by Japanese forces during World War II, has been located off the coast of California. Known as the "Phantom Ship of the Pacific," the vessel was found using three autonomous underwater drones that explored nearly 130 square kilometers (50 square miles) of the ocean floor, as reported by Digi24. These orange, six-meter-long drones, resembling torpedoes, utilized advanced sonar technology to detect the wreck in deep waters more than 100 kilometers (62 miles) from San Francisco. Resting on the ocean floor in what is now the Cordell Bank National Marine Sanctuary, the U.S.S. Stewart (DD-224) measures 95 meters (312 feet) in length. Despite being overrun by marine life, the ship is remarkably intact and upright. "The level of preservation is exceptional for a vessel of its age and may be one of the best-preserved examples of a four-stack destroyer in the U.S. Navy," stated Maria Brown, the sanctuary's administrator... ...The U.S.S. Stewart's storied past dates back to its sinking in 1942 near Java, Indonesia, after being captured and repaired by Japanese forces. Post-war, the U.S. Navy reclaimed the ship and used it as a target for gunnery practice, sinking it on May 24, 1946."
