(CNN) It's been 75 years since the USS Grayback went missing with 80 sailors aboard. Now, an organization that searches for sunken World War II submarines has solved the mystery of where it went down.

On Sunday, undersea explorer Tim Taylor and his team at the Lost 52 Project announced that they had located the long-lost submarine on June 5 about 1,427 feet underwater off Okinawa, Japan.

Last year, researcher Yutaka Iwasaki found that the Navy had originally made an error in translating the Japanese war records that detailed where the Grayback had likely sunk. All this time, the Navy's historical records had listed an incorrect longitude for the submarine's location.

Armed with that information, as well as newly discovered and translated Japanese mission logs, Taylor told CNN that his team set out on an expedition to search for the Grayback, this time searching in the area southwest of Okinawa.

With the help of autonomous underwater vehicles, remotely operated vehicles and advanced imaging technology, the team discovered the Grayback about 100 miles from the area where it was originally thought to have gone down.
