7. What was the precious cargo the USS Indianapolis delivered to the island of Tinian on July 26, 1945?
From Quiz USS Indianapolis (CA-35)
Answer:
components for atomic bomb
The USS Indianapolis delivered components and uranium of the atomic bomb known as "Little Boy." Afterwards, the USS Indianapolis departed Tinian for Guam. While at Guam they received orders to travel to Leyte, in the Philippines, to participate in target practice with the battleship USS Idaho (BB-42) in preparation for the invasion of Japan. Captain McVay requested an escort, from a destroyer, because his ship lacked anti-submarine detection equipment; however, his request was denied. On July 28, 1945, the USS Indianapolis departed Guam, thus becoming the only ship to transit across the Philippine Sea without an escort during the war. On August 6, 1945, "Little Boy" was dropped on Hiroshima, Japan. (Reference: "Clash of the Carriers : The True Story of the Marianas Turkey Shoot of World War II," New York: Coonts, 1998.)
