Did the USS Indianapolis Deliver the Atomic Bomb?
Yes, the USS Indianapolis played a crucial role in delivering components of the atomic bomb that would later be dropped on Hiroshima. The ship transported the enriched uranium, as well as other essential parts, to Tinian Island in July 1945. This mission was extremely secretive and undertaken at high speed.
The Secret Mission to Tinian
In July 1945, the USS Indianapolis was assigned a top-secret mission: transporting components critical to the atomic bomb project, codenamed “Project Alberta.” These included half of the world’s then-supply of enriched uranium (U-235) for the “Little Boy” bomb, as well as other vital parts, from the naval base at Mare Island in California to Tinian Island in the Mariana Islands. The secrecy surrounding the mission was so stringent that even the ship’s captain, Charles B. McVay III, was not fully aware of the nature of his cargo until after the delivery was complete.
The Indianapolis set a record-breaking speed of 29 knots (33 mph) to deliver its cargo, arriving at Tinian on July 26, 1945. The speedy delivery was crucial to the timely execution of the bombing of Hiroshima. After offloading its precious cargo, the ship was dispatched for further duty in the Pacific Theater.
The Tragic Sinking
After leaving Tinian, the USS Indianapolis was torpedoed by the Japanese submarine I-58 on July 30, 1945. The ship sank in just 12 minutes, leaving hundreds of sailors stranded in shark-infested waters. Due to communication errors and the mission’s secrecy, the sinking went unnoticed for several days. Only 316 of the nearly 1,200 crewmen survived. The sinking of the USS Indianapolis remains one of the worst maritime disasters in US Naval history.

The Legacy of the Indianapolis
The sinking of the USS Indianapolis cast a long shadow. Captain McVay was court-martialed and wrongly convicted of endangering his ship. This verdict was widely criticized, and McVay was eventually exonerated decades later. The story of the USS Indianapolis, both its critical role in ending World War II and the tragic loss of life, continues to be remembered and studied as a significant event in naval history.
