The first atomic bomb used against mankind exploded at 8.15 over Hiroshima.
July 16, 1945 just before dawn.
The very first atomic bomb was exploded in a test in the New Mexico desert on July 16, 1945. If you'd like to look up more information about it, you can look up the codename "Trinity".
JulY 16, 1945 on the top of a 100 foot steel tower about half an hour before dawn. This was called the Trinity test shot.The first used in combat exploded on August 6, 1945 over Hiroshima.
the first atomic bomb leveled nothing. That was exploded at the Trinity test site. The first bomb used in war was at Hiroshima Japan, and pretty much destroyed everything in a 3 mile radius. That is just over 7 square miles.
The second atomic bomb, "Fat Man" was dropped on Nagasaki August 9, 1945 and exploded at 11:02 AM (JST). (The first atomic bomb, "Little Boy", was dropped on Hiroshima, Japan, on August 6 1945.)
Because it wasn't ready. Germany surrendered May 8, 1945; the first atomic device was test exploded July 16, 1945.
The 1st atomic bomb codenamed the "Gadget" was exploded on July 16, 1945 SW of Socorro, New Mexico. It was an implosion type bomb using Plutonium 239. It was a test of nuclear bombs codenamed the "Trinity" test.The 2nd atomic bomb codenamed "Little Boy" was exploded on August 6th, 1945 over the city of Hiroshima in Japan. It was a gun type bomb using Uranium 235. It was the 1st bomb dropped in anger.The 3rd atomic bomb codenamed "Fat Man" was exploded on August 9th, 1945 over the city of Nagasaki. Like the Gadget it was an implosion type bomb using Plutonium core.
The first atomic bomb didn't explode in China, it exploded in New Mexico, USA July 25, 1945. I'm 95-99% sure New Mexico had the first one.
