Images from the three autonomous underwater vehicles used to explore the wreck show it is in remarkably good condition after more than 80 years under the waves.

It was sink there during target practice in 1946 by rocket from U.S. warplanes and shells from a U.S. warship . But its exact localization was unknown , until the wreck was rediscovered by three autonomous underwater vehicle ( AUVs ) deployed by the marine robotics companionship Ocean Infinity .

fit in toThe New York Times , the AUVs searched a 37 - square - nautical - mi ( 49 straight miles , or 127 straight km ) area of the seafloor in under 24 hours .

" We covered it very speedily , and in high resolution,“Andy Sherrell , Ocean Infinity ’s managing director of maritime operation , evidence the newsprint .

The Stewart jump the war as a U.S. destroyer designated DD-224 and was ordered to Borneo in November 1941 , shortly before the U.S. entered World War II . It served as an escort vessel with other American warship in the first months of the Pacific War , but it was badly damaged by gunshot from Japanese warships near Bali in February 1942 , during the Battle of Badung Strait .

The Stewart manage to come back to Surabaya on the island of Java . But the port amount under Nipponese attack , so the vessel was scuttled — designedly sink — by its own crew , who set off explosive in its hull . A year later on , however , Japanese raised the recessed warship and it served as a patrol gravy boat for the Imperial Japanese Navy until the war ended in 1945 .

The ship again fall under U.S. ascendancy when Japan surrendered on Sept , 2 , 1945 . The vessel was in short recommissioned as DD-224 by the U.S. Navy , but by then it was in poor shape . It was finally decommissioned in May 1946 and then used for object drill .

" The USS Stewart symbolise a singular opportunity to study a well - preserved example of early twentieth - one C destroyer pattern , " maritime archaeologistJames Delgado , who was formerly with NOAA and is now a aged frailty president at Search , say in the statement .

" Its story , from U.S. Navy service to Nipponese capture and back again , makes it a powerful symbol of the Pacific War ’s complexity , " he said .
