Which aircraft dropped the first nuclear bomb on Hiroshima in WWII?

The correct answer identifies the Enola Gay as the aircraft that dropped the first nuclear bomb on Hiroshima during World War II. This historical aircraft, a B-29 Superfortress, carried out the mission on August 6, 1945, and was named after the mother of the pilot, Colonel Paul Tibbets. The bomb dropped was code-named "Little Boy," which is often confused with the aircraft itself. Understanding this distinction is essential because while "Little Boy" refers specifically to the bomb, the Enola Gay is significant as the delivery system that brought it to its target, marking a pivotal moment in history. The use of the atomic bomb on Hiroshima was a major factor that contributed to the conclusion of the war in the Pacific.
