The World War Two heavy cruiser USS Indianapolis has been found in the Pacific Ocean, 72 years after its sinking by a Japanese submarine. The warship was discovered 18,000 feet beneath the surface. The Indianapolis was destroyed returning from its secret mission to deliver parts for the atomic bomb which was later used on Hiroshima. <br/><br/>Of the 1,196 men on board, just 316 were rescued – the largest loss of life at sea in the history of the US Navy. Microsoft co-founder Paul Allen, who led the civilian search team, said the discovery was truly humbling. The USS Indianapolis was destroyed on 30 July 1945 when, somewhere in the Philippine sea between Guam and Leyte, it was hit by a torpedo from a Japanese submarine.
