Wreckage from the USS Indianapolis was discovered on Aug. 18 by the expedition crew of Paul G. Allen’s Research Vessel (R/V) Petrel. The Indianapolis was found 5,500 meters below the surface, resting on the floor of the North Pacific Ocean.
The Indianapolis was tragically 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 deploy much of its life-saving equipment. Prior to the attack, the Indianapolis had just completed its secret mission of delivering components of one of the two nuclear weapons that were dropped on Japan. Of the 1,196 sailors and Marines onboard, only 316 survived.
