Wreckage from the USS Indianapolis located

A team of civilian researchers led by entrepreneur and philanthropist Paul G. Allen said Saturday they have found the wreck of the World War II cruiser USS Indianapolis (CA 35), which was lost July 30, 1945.

This is a significant discovery considering the depth of the water in which the ship was lost — more than 18,000 feet, the U.S. Navy and Paul Allen said in press releases issued Saturday. Around 800 of the ship’s 1,196 Sailors and Marines survived the sinking, but after four to five days in the water — suffering exposure, dehydration, drowning, and shark attacks — only 316 survived.

The wreck was located by the expedition crew of Research Vessel (R/V) Petrel, which is owned by Allen, resting on the floor in the Phillipine Sea.

“To be able to honor the brave men of the USS Indianapolis and their families through the discovery of a ship that played such a significant role in ending World War II is truly humbling,” said Allen, whose real estate portfolio includes the “Thurston Estate” on Kailua Bay. “As Americans, we all owe a debt of gratitude to the crew for their courage, persistence and sacrifice in the face of horrendous circumstances. While our search for the rest of the wreckage will continue, I hope everyone connected to this historic ship will feel some measure of closure at this discovery so long in coming.”

Indianapolis was lost in the final days of World War II when it was torpedoed by a Japanese submarine in the early morning hours of July 30, 1945. The Indianapolis sank in 12 minutes, making it impossible to send a distress signal or deploy much of its life-saving equipment. Prior to the attack, the Indianapolis had just completed a secret mission delivering components of the atomic bomb used in Hiroshima that would ultimately help end the war in the Pacific, the Navy said.

“Even in the worst defeats and disasters there is valor and sacrifice that deserves to never be forgotten,” said Sam Cox, director of the Naval History and Heritage Command. “They can serve as inspiration to current and future Sailors enduring situations of mortal peril. There are also lessons learned, and in the case of the Indianapolis, lessons re-learned, that need to be preserved and passed on, so the same mistakes can be prevented, and lives saved.”

Others have searched for Indianapolis in the past. Among the elements that made this effort different was Allen’s recent acquisition and retrofit of the 250-foot R/V Petrel with state-of-the-art subsea equipment capable of diving to 3.5 miles in depth.

“The Petrel and its capabilities, the technology it has and the research we’ve done, are the culmination years of dedication and hard work,” said Robert Kraft, director of subsea operations for Allen. “We’ve assembled and integrated this technology, assets and unique capability into operating platform, which is now one amongst very few on the planet.”

The other key factor in the discovery was information that surfaced in 2016 when Richard Hulver, historian with the Naval History and Heritage Command, conducted research that led to a new search area to the west of the original presumed position.

Hulver’s research identified a naval landing craft that had recorded a sighting of Indianapolis hours before it was torpedoed. Using that information, the research team developed a new position and estimated search, which was still a daunting 600 square miles of open ocean.

The 13-person expedition team on the R/V Petrel is in the process of surveying the full site and will conduct a live tour of the wreckage in the next few weeks.

Their work is compliant with U.S. law, respecting the sunken ship as a war grave and not disturbing the site. USS Indianapolis remains the property of the U.S. Navy and its location will remain confidential and restricted by the Navy.

The crew of the R/V Petrel has collaborated with Navy authorities throughout its search operations and will continue to work on plans to honor the 22 crew members still alive today, as well as the families of all those who served on the highly decorated cruiser, the Navy said.

“For more than two decades I’ve been working with the survivors. To a man, they have longed for the day when their ship would be found, solving their final mystery,” said Capt. William Toti (Ret), spokesperson for the survivors of the USS Indianapolis. “They all know this is now a war memorial, and are grateful for the respect and dignity that Paul Allen and his team have paid to one of the most tangible manifestations of the pain and sacrifice of our World War II veterans.”
