An autonomous drone fleet overseen by Ocean Infinity has rediscovered the USS Stewart, the one US Navy destroyer ever captured by Japanese forces throughout World Battle II. The marine robotics firm’s trio of orange, 20-foot-long underwater robots discovered the historic vessel whereas mapping what’s now the 1,286-square-mile Cordell Financial institution nationwide marine sanctuary off the California coast. Also referred to as the “Ghost Ship of the Pacific,” the 314-foot-long ship has spent the previous 78 years resting roughly 3,500 ft under the ocean’s floor, and seems to stay virtually utterly intact and upright.
“This stage of preservation is phenomenal for a vessel of its age and makes it probably one of many best-preserved examples of a US Navy ‘four-piper’ destroyer identified to exist,” Maria Brown, superintendent for each Cordell Financial institution and Higher Farallones nationwide marine sanctuaries, stated in an announcement to The New York Times on October 1.
The USS Stewart’s story is exclusive in US maritime historical past, making it one of the crucial sought-after wrecks for many years. Initially sunk and deserted after sustaining substantial battle injury, Japanese forces managed to boost the destroyer, restore it, and reenlist it towards America as a naval convoy escort. Throughout its second life, Allied pilots started recounting what gave the impression to be certainly one of their very own ships far inside enemy territory, incomes the Stewart its “Ghost Ship” moniker.
The US Navy recovered the Stewart following Japan’s give up and meant to tow it again to its unique house. Whereas en route, nevertheless, its engines gave out close to Guam, forcing the fleet to tow it the remainder of its journey. As soon as again within the US, the “Ghost Ship of the Pacific” was given a dramatic burial at sea on Might 24, 1946: Used as goal observe for naval forces, it nonetheless took an estimated 2 hours of fireside to lastly sink it for good. However within the years since, the precise coordinates of its location have been misplaced.
Quite a few makes an attempt have been made previously to seek out the USS Stewart, however the profitable August search reportedly happened virtually accidentally. Ocean Infinity, which beforehand used its drones to assist rediscover the USS Nevada and Endurance wrecks, initially wished to easily check out a number of of its largest autonomous underwater robots concurrently. That’s when Russ Matthews, president of the Air/Sea Heritage Basis nonprofit, advised the drones be used to scan for the Ghost Ship after he discovered coordinates of the tugboat that pulled it out to the world of its last scuttling. Whereas it often takes weeks to map out 37-square-nautical-miles of ocean flooring, the drones managed to seek out the Stewart in a couple of hours.

“We’re within the midst of, I believe, a radical change in ocean discovery,” Jim Delgado, senior vice chairman of SEARCH, Inc, a maritime archeology agency additionally concerned within the challenge, advised The New York Occasions on Tuesday.
Except for long-lost shipwrecks, autonomous mapping drones can be utilized to determine promising ocean flooring house for the development of wind farms, in addition to chart routes for underwater cabling.
