There are atomic bomb casings that remain from the 1945 to 1948 period, but most (if not all) were probably built postwar. There were only four functional atomic bombs actually built prior to the end of the war and three of those were detonated (gadget, little boy, fatman), leaving only one (unnamed) actual World War 2 atomic bomb remaining after the war. This bomb was either detonated later in one of the nuclear test shots or its special nuclear materials were recycled to make newer more efficient/safer atomic bombs by 1949. Also the conventional explosives used in the explosive lenses of world war 2 implosion type atomic bombs (composition b, baratol) are much too unstable for use in weapons intended for long term stockpiling.
Several museums preserve atomic bomb casings, a few are:
Another thing to be aware of is that not all apparent "fatman" casings exhibited in museums are really atomic bomb casings, some are pumpkin bomb casings (a pumpkin bomb was a large conventional blockbuster bomb used for practice drops by atomic bomb crews, several were dropped on Japan prior to the actual atomic bombings, they weighed the same and had the same size and shape as a real MK-III), and others are mockups built specifically for the exhibit.
In 2003 I visited several museums with atomic bomb casings, that year none of them had little boy on exhibit. I found out why in one museum where they had replaced the little boycasing in the exhibit with a sign that stated all of them had been removed from museum exhibits to be modified to remove one external feature still classified top secret!!! So even if it is a real period casing, it may not appear as it did originally as parts may have been removed or modified for security or other reasons.
There have not been any attacks using atomic bombs or missiles since World War II (as of today, May 4th, 2011). There have however, been many nuclear weapons tests - where controlled explosions have been conducted. Most of these have occurred underground to reduce nuclear fallout.
During World War II, the use of atomic bombs to defeat Japan continues to be debated: was it necessary (as a 'necessary evil' or otherwise) or was it not? At the time, it is undeniable that Allied leaders were fearful of the casualties that would follow from any land-invasion of Japan. Moreover, they were not convinced that a land-invasion of Japan would even end the war. With these points in mind, it is very reasonable to consider the use of atomic bombs as sound and prudent, even if not necessary.
At this time (2012) neither the US or Russia makes any. Other countries may be making small numbers.
The US dropped 50 atomic bombs from airplanes between 1945 and 1962 (2 in combat on Japan, 48 in test shots). Over 1000 were detonated in other ways in test shots between 1945 and 1992. The USSR, UK, and France also dropped atomic bombs from airplanes and detonated many in other ways in test shots (but never used any in combat).
Yes, two nuclear bombs were used in warfare during World War II. The United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki in August 1945. It remains the only time nuclear weapons have been used in warfare to date.
yes they have alot bombs waiting for any reason really
Yes, plenty.
no
Atomic bombs were not used anywhere in Europe in WW2. The only country that atomic bombs were dropped on in any war is Japan.
None.
Many atomic bombs were detonated for "test" purposes. Fortunately none were used in war.
Noplace, the US did not have any atomic bombs in 1944. Nobody had atomic bombs in 1944.
1 WW2 was the only war to detonate atomic bombs. Pray no one ever uses any again.
No, only two atomic weapons have been used in war. Both were dropped on Japan.
Yes, a few hundred.
Any bomb that gets its destructive energy from the atomic nucleus.
No, the Japanese military did not drop any bombs on the USA after the atomic bombs were used on Japan. The bombs and pending invasion by the Soviets and the Americans (and allies) motivated the Emperor Hirohito to surrender to the Allied Forces.
