The first atomic bomb to be detonated was on July 16, 1945, at New Mexico's trinity site. The bomb was called gadget. It was not dropped, but was instead detonated on the top of a 100 foot steel tower.

The first Atomic Bomb (called little boy) dropped was on August 6, 1945 on the city of Hiroshima. The second atomic bomb (called fatman) dropped was on Nagasaki three days later. The United States dropped these bombs on Japan in order to end World War II. Then on August 14, 1945, the Japanese surrendered. Later on September 2, 1945, the Japanese signed the formal instrument of surrender.

A third atomic bomb had been shipped from Los Alamos sometime before August 14, 1945 and arrived in San Francisco on August 18, 1945 to be flown across the Pacific to Tinian. As Japan was already surrendering this bomb was returned to Los Alamos, becoming the first Atomic Bomb in the US nuclear stockpile. Had the war continued this bomb could have been dropped within a day or two of August 25, 1945.

The US had production plans and the industrial infrastructure capable of manufacturing and the bomber aircraft needed to drop on Japan 20 more atomic bombs before the end of 1945 had the war continued. Fortunately for everyone only the first 2 of these 23 bombs were actually needed to bring WW2 to a close.

The first atomic bomb was dropped on August 6,1945. This bomb was dropped on a city in Japan, as a possible solution to end WWII. Following the second atomic bomb dropping in Japan a few days later, the Japanese surrendered, meaning that the United States had won the war. Following their victory, the United States demanded that Japan surrendered Korea in their defeat. Korea was later split into North and South Korea, and North Korea still blames the United States for the separation of the country.
