The [Manhattan] project succeeded in developing and detonating three nuclear weapons in 1945: a test detonation of a plutonium implosion bomb on July 16 (the Trinity test) near Alamogordo, New Mexico; an enriched uranium bomb code-named "Little Boy" on August 6 over Hiroshima, Japan; and a second plutonium bomb, code-named "Fat Man" on August 9 over Nagasaki, Japan.

The first atomic bomb detonated was the Trinity Test Bomb on July 16, 1945. It had the estimated explosive power eqivalent of 20,000 Tons of TNT. It was identical to the bomb dropped on Nagasaki 3 weeks later. The Hiroshima bomb was of a different design and was about 15,000 Tons equvalent.
On August 9, 1945, the "Fat Man" nuclear bomb was detonated over Nagasaki.
The first atomic bomb was made August 1945. My ? to you is," Why did they even start making those atomic bomb anyway?
