It was made in 1951 and dropped for the first time in 1952.
Atom or atomic bomb is an older term. The modern term is Nuclear Weapon or Nuclear Device. Then of course there are Thermonuclear weapons (typically these are the large strategic nukes), which are also called "Hydrogen Bombs". These typically consist of a primary or trigger, which is basically a small nuclear weapon. This tiny nuke sets off a larger secondary inside the weapon which causes a fusion reaction and a very large explosion.
The hydrogen bomb was not invented until the 1950's. The planes that dropped the first fission-type atomic bombs in World War II are the Enola Gay and Bockscar.
No hydrogen bombs were dropped on Vietnam. No nuclear weapons of any kind were used in Vietnam.
Those hydrogen bombs were 20 times stronger at the beginning and later all got worst in the arms race.
The first successful hydrogen bomb was detonated (not launched or dropped--it was a 62-ton fixed structure) on November 1, 1952.
A hydrogen bomb was not dropped on Japan. It was dropped years later as a test and to determine how it acted in comparison to the plutonium and uranium bombs.
Only two atomic bombs were used against man kind in war and neither of those were a thermonuclear or hydrogen bomb.
The hydrogen bomb was first successfully tested in 1952 by the United States.
November 1, 1952 was the day of the first H bomb being dropped in the Pacific. It was dropped at Enewatek Atoll.

No, hydrogen bombs were not dropped on Hiroshima. The atomic bomb "Little Boy" was dropped on Hiroshima by the United States on August 6, 1945, during World War II. Hydrogen bombs are a more powerful type of nuclear weapon that was developed later.
