This post has been updated with video from R/V Petrel of the wreck of USS Juneau.

The research team funded by billionaire Paul Allen has found the wreckage of the Atlanta-class cruiser USS Juneau (CL-52) near the Solomon Islands, according to a Monday announcement.

The ship was sunk during the 1942 Battle of Guadalcanal by an Imperial Japanese Navy torpedo, killing 687 crewmembers. Aboard were the five Sullivan brothers. The Sullivans joined the Navy in early 1942, asked to serve together and were assigned to Juneau. The brothers were from Waterloo, Iowa.

The crew of Allen-owned Research Vessel (R/V) Petrel discovered the wreck on St. Patrick’s Day as part of an ongoing research expedition in the South Pacific.

“We certainly didn’t plan to find the Juneau on St. Patrick’s Day. The variables of these searches are just too great,” Robert Kraft, director of subsea operations for Paul Allen, said in a statement.

“But finding the USS Juneau on St. Patrick’s Day is an unexpected coincidence to the Sullivan brothers and all the service members who were lost 76 years ago.”

The death of the Sullivan brothers was a major touchstone for Americans at home during the early days of U.S. involvement in World War II.

“News of the deaths of all five brothers became a rallying point for the war effort, with posters and speeches honoring their sacrifice. Extensive newspaper and radio coverage of the incident made the loss of the brothers a national story, producing ‘a wave of humility and sympathy,’ and condolences poured in on the Sullivan family in Waterloo, Iowa,” according to Navy History and Heritage Command.

The Navy has named two destroyers in honor of the Sullivan brothers.

“As the fifth commanding officer of USS The Sullivans (DDG-68), a ship named after five brothers, I am excited to hear that Allen and his team were able to locate the light cruiser USS Juneau (CL-52) that sunk during the Battle of Guadalcanal,” Vice Adm. Rich Brown, commander of Naval Surface Forces, said in a statement.

“The story of the USS Juneau crew and Sullivan brothers epitomize the service and sacrifice of our nation’s greatest generation.”

Allen has also discovered the wrecks of cruiser USS Indianapolis and carrier USS Lexington.
