The loss of USS
Indianapolis CA-35 was a tragic moment following the completion of a secret mission
that directly contributed to the end of World War II. After a successful high-speed run to deliver atomic bomb
components to Tinian, the decorated Portland-class cruiser continued to Guam. Indianapolis was en route
from Guam to Leyte when she was torpedoed and sunk by the Japanese submarine I-58 within the first hour of
30 July 1945.
