Tim and his team were searching for the U.S.S. Grayback. The Lost 52 Project was the cause behind this salvage operation. This project is entirely dedicated to locating the 52 different U.S. submarines that mysteriously disappeared in World War Two.

Embarking on a Combat Patrol

The Grayback embarked on a combat patrol on January 28th, 1944, from Pearl Harbor. It was the sub’s tenth and final mission, as the Grayback was later posted, the submarine as being missing in late March 1944. However, a message was sent back to base before its disappearance.

The Message

Before its disappearance, the message sent by the Grayback stated that it had sunk two Japanese freighters and hit another two. However, the submarine had also caused severe damage to more Japanese freighters, which left the sub with only two torpedoes.

Running Low

The Grayback informed base that the sub was running low and ammunition and was going to head to Midway Atoll in the North Pacific to stock up again. This was the last radio message received from the Grayback. Navy commanders expected the submarine to dock at Midway Atoll on March 7th, 1944.

Building the Grayback

There wasn’t any trace of one of the U.S. Navy’s assets. The Grayback’s life began on April 3rd, 1940. This was when shipbuilders laid her keel down in Groton at Connecticut’s Electric Boat Company, which was known to be in good hands as the skilled workers had been building submarines since 1899.

The weaponry fired at these Japanese crafts had caused considerable damage to a hatch located on the Grayback’s hull. This resulted in leakage forcing the sub to set off to port in Brisbane, Australia. The Grayback was able to survive until her seventh tour, starting in Brisbane in 1943.

At Midway Atoll

The ‘wolfpack’ was formed when the Grayback, U.S.S. Cero, and Shad joined at Midway Atoll. The tactic of combining submarines to work together has proved to be highly successful when used by German U-boats, and the ‘wolfpack’ was no different.

The Three Subs

The three subs, known as the ‘wolfpack,’ were extremely effective and accounted for the sinking of more than 38,000 tons of Japanese crafts while severely damaging a further 3,300 tons. Once using up all of the subs’ torpedoes, the wolfpack returned to Midway Atoll.

Heading for the East China Sea

After returning to Midway Atoll, the Grayback was quick to set off on her next mission on December 2nd, 1943, for the East China Sea from Pearl Harbor. During this mission, the sub used all of her torpedoes in five days while sinking for Japanese ships in the process.

Many Decades Later

It would only be decades later before anyone learned of what exactly happened to the Grayback and the 80 crew aboard the vessel. The initial belief was that the sub had sunk beneath under the waves at approximately 100 miles of the southeast of Okinawa.

A Critical Error

The information used to create this belief came from records that had been kept by the Japanese. However, a single digit in a map reference had been transcribed wrong. Due to this, the Grayback was actually far away from this initial location.

Re-Examining the Case

The assumption was believed for many years. However, it wasn’t until 2018 that Tim Taylor decided to re-examine the Grayback’s disappearance. Tim is the founder of the Lost 52 Project, which is a private enterprise that’s dedicated to investigating the disappearances of 52 submarines during the Second World War.

The Search for the Submarine

The organization team members got in touch with Yataka Iwasaki, who was a Japanese researcher. The purpose of this was for the researcher to comb through the files of the Sasebo base for information on the Grayback. This would help locate the vessel and uncover some answers.

The Single-Digit Error
