The American wreck was found after 72 years on the seabed

The wreck of the ship carrying materials and parts of the two atomic bombs dropped on Hiroshima and Nagasaki was found in the Pacific Ocean.

American tech billionaire Paul G. Allen claims a research ship of his organization identified the position of the wreck of USS Indianapolis in the Philippine Sea on August 18, according to USA Today.

The Indianapolis ship was sunk by a Japanese submarine in 1945, marking a major loss of life in US Navy history. The detection of the wreck will help researchers learn about the disaster that happened with the ship.

On July 30, 1945, when World War II was about to end, the USS Indianapolis hit two torpedoes from the Japanese submarine I-58 and sank only 12 minutes later. The ship has just completed the task of secretly transporting materials to build two nuclear bombs later thrown by the US on Japan's Hiroshima and Nagasaki cities.

Of the 1,197 people on board Indianapolis, about 300 sink with the ship. Nearly 900 people survived in shark waters with very few lifeboats and almost no food or water. For 4 days, people without life vests cling to people with robes while white sharks and tiger sharks surround the wreck to attack the surviving union.

"Very soon there are hundreds of shark fins around us , " remembers a sailor named Harold Eck. "The first attack I witnessed fell on a sailor who was washed away from the group by the wave. I heard screams and saw him torn apart and then blood came out."

This is the worst shark attack recorded in history. Only 317 people, equivalent to a quarter of the original crew, survived a series of horrifying days.

After the war ended, surviving sailors from the Indianapolis ship knew the truth about the secret mission that made them the target of Japanese torpedoes. At that time, they all assumed that the ship was only transporting a large wooden crate from a small yard of the US Navy in San Francisco to Tinian Island, the US air base in the Pacific Ocean. In fact, this wooden barrel contains about half of the world's enriched uranium and parts to make the atomic bomb.
