USS Grayback (USS-208)
 

A new report just out a couple of days ago, the USS Grayback (SS-208), a Tambor -class submarine, has been found.

The Grayback's tenth patrol, her most successful in terms of tonnage sunk, was also to be her last. She sailed from Pearl Harbor on 28 January 1944, for the East China Sea. On 24 February Grayback radioed that she had sunk two cargo ships 19 February and had damaged two others (Taikei Maru and Toshin Maru sunk). On 25 February she transmitted her second and final report. That morning she had sunk tanker Nanho Maru and severely damaged Asama Maru. With only two torpedoes remaining, she was ordered home from patrol. Due to reach Midway on 7 March, Grayback did not arrive. On 30 March ComSubPac listed her as missing and presumed lost with all hands.

On November 10, 2019, a private research group, Lost 52 Project, announced it had found the wreck of Grayback off the coast of Okinawa, in June 2019.[10] The submarine sits upright on the bottom in 1,400 feet (430 m) of water.

The wreck has severe damage aft of the conning tower, consistent with reports of a direct bomb hit in that area.[11] The bow is broken off at an angle and a portion near the stern also imploded. Finally, the nameplate remains attached to the intact bridge.

The wreck was discovered about 100 miles (160 km) from the coordinates established by the U.S. Navy in 1946 because of an error in their translation of the original Imperial Japanese Navy combat action reports.
