The cities were destroyed by atomic bombs of two separate types and composition.
Hiroshima was bombed by the United States Army Air Force on the 6th August 1945. The bomb was a gun-type Fission weaponcodename "Little Boy". It contained 60 Kg of uranium-235. It was released from the B-29 Enola Gay piloted by Colonel Paul Tibbets at 08:15 (Hiroshima time) and exploded at a height of 600 Meters 57 seconds later.
Nagasaki was bombed on the 9th August 1945. The Bomb was a implosion type device using 6.4 Kg of Plutonium-239, codename "Fat Man". The orginial target was Kokura, but clouds prevented its targeting so pilot Charles W. Sweeney in the B-29 Bockscar decided to attack the secondary target. Again clouds delayed the planned drop but at 11.01 they noticed a break in the clouds and Sweeney ordered the drop. It exploded 47 seconds later at a height of 469 m.

∙ 13y agoNo, they were atomic bombs. Hydrogen bombs were developed later.

∙ 12y agoThat is the only time when atomic weapons were used against mankind. On august 6 1945 the first one was dropped over Hiroshima and 3 days after, the 9th, another was dropped over Nagasaki.

What happened when the waves hit the mountain?
The hills of Nagasaki were some kind of protection but the bomb was a stronger one thus the results were the same like Hiroshima.
What kind of nuclear weapons were used during Pearl Harbor?
No nuclear weapons were used in the Japanese attack on Pearl Harbor on December 7, 1941 as such weapons did not exist and would not exist until July 1945 when the US built the first ones. The first use of a nuclear weapon in war was the US attack on Hiroshima on August 6, 1945; the bomb was a relatively simple and very inefficient (~1%) fast fission neutron chain reaction Uranium-235 (80% enrichment) gun bomb.
Did we drop the hydrogen bomb on Vietnam?
No hydrogen bombs were dropped on Vietnam. No nuclear weapons of any kind were used in Vietnam.
Does Nagasaki still have radiation?
It had been decades without the radiation from the nuclear bomb at Nagasaki.
Which is more powerful an atomic bomb or a nuclear bomb?
They are the same kind of bomb: bombs that derive their energy from the atomic nucleus. It just depends on design and how much of the design yield is from fission or from fusion. Pure fission bombs cannot be built with yields above 1 megaton, but including some fusion the theoretical yield is unlimited.However considering mission, construction costs, size limits, etc. it is usually more practical to build low yield bombs that are part fission part fusion than to try to build high yield bombs of either type.The lowest yield nuclear bomb tested was the US Davy Crocket at 10 tons yield, the highest yield nuclear bomb tested was the USSR Tsar Bomba at 52 to 58 megatons yield (depending on method of measurement). Both were part fission part fusion designs, although the designs were obviously very different: the Davy Crocket was almost entirely fission yield, the Tsar Bomba was over 95% fusion yield and generated the least fallout per kiloton yield of any nuclear bomb detonated in the atmosphere.
What kind of bombings were in hiroshima?
There were one atomic bomb dropped over Hiroshima which used Uranium as fuel the other one was a plutonium fueled bomb dropped over Nagasaki.
Who had dropped the first atomic bomb?
The only nation who used the bomb against man kind is the United States in August 6 and 9 1945 on Hiroshima and Nagasaki, Japan.
What happened when the waves hit the mountain?
The hills of Nagasaki were some kind of protection but the bomb was a stronger one thus the results were the same like Hiroshima.
What kind of bomb exploded in Nagasaki?
It was a plutonium implosion type. So it was an atomic bomb.
When was the atomic bombing ended?
There two atomic bombs used against man kind. The Hiroshima bomb drooped on August 6 1945 and the other one dropped over Nagasaki on August 9 1945.
Where was the first atomic bomb used?
In the history of warfare, only two nuclear weapons have been detonated offensively. The first was at Hiroshima, Japan, and the second was at Nagasaki, Japan. The weapons, the Little Boyand the Fat Man respectively, were dropped by the U.S. There was one nuclear test, the so-called Trinity test, that preceeded these bombings. In that test, the U.S. actually set off a nuclear device for the first time in history. Following that successful test, the other two bombs were built and deployed.
Was there a war between russia and japan during 1945?
There was i believe a short war between them when russia invaded japan through occupied mongolia, the US then dropped the bomb on hiroshima and nagasaki a few months later, so it was kind of irrelevant to the war.
What kind of plane dropped the aotmic bomb on Hiroshima?
The B-29 Bomber named The Enola Gay.
How did they name the atomic bombs in World War I?
There were no atomic weapons in World War 1, they hadn't been developed then- I think you must mean World War 2. The first bomb, to be dropped on Hiroshima, was named 'Little Boy'- the one dropped on Nagasaki was called 'Fat Man'. The 'Little Boy' bomb was so named because it was the first ever nuclear weapon of it's kind to be used in combat, and in time would lead to nuclear weapon development 'growing up' to bigger and more devastating bombs- it was probably also as a kind of sick irony, since the last thing it was was 'little'!! The 'Fat Man' bomb was so named because of it's shape- round and fat with a boxed tail.
What kind of nuclear weapons were used during Pearl Harbor?
No nuclear weapons were used in the Japanese attack on Pearl Harbor on December 7, 1941 as such weapons did not exist and would not exist until July 1945 when the US built the first ones.

What are facts about the atomic bombing?
There were two atomic bombs used against man kind. The one called little boy, was dropped Hiroshima and the other one called fat man was dropped over Nagasaki. The dates were August 6 and 9 1945.
Did we drop the hydrogen bomb on Vietnam?
No hydrogen bombs were dropped on Vietnam. No nuclear weapons of any kind were used in Vietnam.
