USS Indianapolis (CA-35)
USS Indianapolis (CL/CA-35) was a Portland-class heavy cruiser of the United States Navy, named for the city of Indianapolis, Indiana. Launched in 1931, she was the flagship of the commander of Scouting Force 1 for eight years, then flagship for Admiral Raymond Spruance from 1943 to 1945 while he commanded the Fifth Fleet in battles across the Central Pacific during World War II. In July 1945, Indianapolis completed a top-secret high-speed trip to deliver uranium and other components for "Little Boy", the first nuclear weapon used in combat, to the Tinian Naval Base, and subsequently departed for the Philippines on training duty.
