About the wreck

USS Grayback (SS-208), was a Tambor-class submarine, and was the first ship of the United States Navy to be named for the lake herring Coregonus artedi. She ranked 20 among all U.S. submarines in total tonnage sunk during World War II, with 63,835 tons, and 24th in number of ships sunk, with 14. She was sunk near Okinawa on 27 February 1944. Her wreck was discovered in June 2019.

Diving & visiting

On 10 November 2019, a private research group, Lost 52 Project, announced it had found the wreck of Grayback 50 nautical miles (93 km; 58 mi) south of Okinawa, in June 2019. The wreck was discovered about 100 nautical miles (190 km; 120 mi) from the coordinates established by the U.S. Navy in 1946 because of an error in its translation of the original Imperial Japanese Navy combat action reports. The discovery was officially verified by the U.S. Navy and the families of the deceased crew members were notified. The submarine sits upright on the bottom in 1,400 ft (430 m) of water. The deck gun was found about 400 ft (about 120 m) from the primary wreckage.

The wreck has severe damage aft of the conning tower, consistent with Japanese reports of a direct bomb hit in that area.
