The bombs that were dropped on Hiroshima and Nagasaki were atomic bombs and not nuclear bombs and were designed to explode above the ground and not on impact.
2 Atomic bombs.Answer:Technically, the allies, specifically the US used three atomic bombs to motivate the Japanese to surrender: Fat Man, Little Boy, and the first bomb detonated, the Trinity Device.
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 US had built 4 atomic bombs before the end of WW2 and detonated 3 of those. There were plans and facilities for building another 20 before the end of 1945 had they been needed.Gadget, detonated July 16, 1945 on a steel tower at the Trinity site in what is now White Sands Missile Range in New MexicoLittle Boy, detonated August 6, 1945 over Hiroshima, JapanFatman, detonated August 9, 1945 over Nagasaki, Japanunnamed, arrived in San Francisco on August 18, 1945 returned to Los Alamos (probably could have been dropped on Japan around August 25, 1945)
Some atomic bombs explode on impact, most explode in the air for maximum destruction caused by the explosion spreading out over a wider area.
The atomic bombs did not land, they were detonated 2000 feet in the air above Hiroshima and Nagasaki.
Hiroshima and Nagasaki
Many atomic bombs were detonated for "test" purposes. Fortunately none were used in war.
The bombs that were dropped on Hiroshima and Nagasaki were atomic bombs and not nuclear bombs and were designed to explode above the ground and not on impact.
Where: Two bombs were used, over the cities of Hiroshima, and Nagasaki. When: Both bombs were detonated in 1945, near the end of World War II.
No. Only two atomic bombs (fission bombs) have ever been used in war. August 1945.
Including atomic shells from cannons, and other devices, approximately two thousand.
As of august 1945 the US had the industrial capacity to make 3 atomic bombs a month. In november 1945 this would increase to 7 atomic bombs a month. As Japan surrendered before this, the US scaled back production and had only made 9 atomic bombs by the end of Operation Crossroads in the summer of 1946, five of which had been detonated.

The Manhattan Project began in 1942 and ended in August 1947, with the establishment of the Atomic Energy Commission. A rough estimate is that in this time 15 to 20 atomic bombs had been built, with 5 of those detonated, leaving a stockpile by the time the Manhattan Project ended of 10 to 15 atomic bombs.
No. Hydrogen Bombs have been detonated that make the atomic bomb look small in comparison. The Atomic Bombs dropped on Japan in WW2 were 25 Kton (equivilent to 25000 tons of dynamite), while H bombs can be as big as several hundred Megaton (million tons of dynamite)
The last atomic bomb used in combat was on August 9, 1945. Many more were dropped from airplanes or otherwise detonated in test shots.
