The USS Indianapolis was a Portland-class heavy cruiser of the United States Navy, commissioned in 1932, and it played a vital role in the Pacific theater during World War II. Its most significant and tragic moment came in 1945, during its final mission. The ship was tasked with delivering critical components for the atomic bomb that would later be dropped on Hiroshima, Japan. This mission, which involved transporting the bomb's uranium core to the island of Tinian, was classified, and few knew about the importance of the cargo aboard the ship.

After successfully completing its mission and delivering the components to Tinian on July 26, 1945, the Indianapolis set sail for the Philippines, where it would rendezvous with other ships in the Pacific fleet. The ship's captain, Charles B. McVay III, had orders to take the cruiser directly to its next destination, avoiding the traditional convoy routes to reduce the risk of submarine attack. With the war nearing its end and Japan's defeat imminent, the ship's journey seemed routine, and there was little concern about the potential dangers ahead. The USS Indianapolis was an experienced and battle-tested ship, having served in key naval engagements throughout the war, including the Battle of Leyte Gulf and the Battle of the Philippine Sea.

However, the absence of a convoy left the Indianapolis vulnerable. On the night of July 29, 1945, while traveling through the Philippine Sea, the ship was struck by two torpedoes fired by the Japanese submarine I-58. The attack tore through the hull, causing devastating damage. Within minutes, the ship began to sink, and the crew was thrown into chaos. Many of the crew members perished instantly, while others scrambled into the water, trying to escape the fiery wreckage of the ship. The survivors faced an unimaginable nightmare as they found themselves stranded in the open ocean, with little hope of immediate rescue.
