Lost to the depths of the Pacific Ocean 72 years ago after being sunk by Japanese torpedoes, the wreckage of the USS Indianapolis — the ship that delivered components crucial to "Little Boy," the atomic bomb dropped on Hiroshima — has been located.

A team of researchers led by Microsoft co-founder Paul Allen announced the discovery of the World War II cruiser at a depth of more than 5,500 meters (18,000 feet) on Saturday.

The Indianapolis was torpedoed in the final days of the war by an Imperial Japanese Navy submarine in the early hours of July 30, 1945.
