The first atomic bomb was launched in 1945, by the US. It incinerated Hiroshima and Nagasaki, Japan during WWII The above is half true. That was the first time an atomic bomb was used in war, but the first atomic bomb was detonated at the the Trinity Site in White Sands Missile Range, on July 16, 1945.
The first atomic bomb was detonated at the White Sands Proving ground at a location called Alamagordo in New Mexico in a project know as the Trinity Operation. A few weeks later an aerial atomic bomb exploded above Hiroshima, Japan. Another bomb, an H-bomb, exloded above Nagasaki, Japan 3 days later. At that point, Japan agreed to unconditional surrender, thus saving millions of lives that would have been lost had the Allies had to invade Japan (which was going to start about 2 weeks later).
