What was the nickname and target of the first atomic bomb dropped by the U.S.?

The first atomic bomb dropped by the U.S. was nicknamed "Little Boy" and was targeted at the city of Hiroshima on August 6, 1945. This bomb was a uranium-based weapon and marked a pivotal moment in World War II as it aimed to bring about a swift end to the conflict. The name "Little Boy" was chosen for its small size compared to future atomic bombs, while the target, Hiroshima, was selected due to its military significance and concentration of troops.

The second atomic bomb, named "Fat Man," was dropped on Nagasaki three days later, on August 9, 1945. This bomb was of a different design, using plutonium instead of uranium.

Understanding these details allows for a clearer picture of the historical events surrounding the use of atomic weapons and their devastating effects on cities and populations.
