Atomic Bombs
Atomic bomb is an explosive device in which a large amount of energy is released through nuclear reactions. This makes an atomic bomb, more properly called a nuclear weapon, a much more powerful device than any conventional bomb containing chemical explosives. The first Atomic Bombs were used during World War 2 in 1945 by the US onto 2 Japanese cities.

What was the actual number of casualties the atomic bombs dropped on Hiroshima and Nagasaki?
some places say 140,000 casualties and some say up to 350,000.
im not sure which one is correct, but i do know around 70,000 people died at nagasaki immediately.
hope this helps a bit :)
Was the US the only country that had atomic bombs during World War 2?
Yes, other countries had programs to research nuclear weapons but none developed working ones before the war ended.
When was the first atomic bomb dropped and why?
After the Japanese had bombed Pearl Harbor, the Allies bombed Japanese cities including Tokyo. In 1943, the Allies won the Battle of Midway. Shortly after joining WWII (1942) the US started a top secret project known as the Manhattan Project. Led by American scientist J. Oppenheimer, the team worked for 3 years to build an atomic bomb. After officials successfully tested the bomb, they told the Japanese to surrender, or they would face destruction. The Japanese refused to give in. On August 6, 1945, The B-29 bomber 'Enola Gay' dropped an atomic bomb on the city of Hiroshima. They still didn't surrender so another atomic bomb was dropped. On August 14, Japan surrendered.
Long story short, the Japanese wouldn't surrender so they dropped the atomic bomb. The Japanese still didn't surrender so they dropped another atomic bomb killing more people and they finally surrendered on August 14.
Why did America drop a atomic bomb on hiroshima?
1. America attacked Hiroshima as an act of revenge for them attacking Pearl Harbor.
2. Because America and Japan were engaged in a war & because there was a military base in Hiroshima
Who decided to drop the atomic bomb on japan and why?
President Harry Truman because he (mainly) wanted to avoid having to spend millions of troops in an invasion of Japan to get them to surrender. He also just wanted to show the world that we were the best and we intended to make it stay that way and at a forced peace.
What was the name of the first and second atomic bombs in World War 2?
The Hiroshima bomb was called "Little Boy" and the Nagasaki weapon was called "Fat Man". The plane that dropped the Hiroshima bomb was called "Enola Gay" which was named after the generals mother.
President Harry S. Truman reasoned that a full scale invasion of Japan would cost too many American lives and would still devastate the nation. The United States needed something spectacular too make the traditionally "death over defeat" nation surrender, and a conventional invasion would simply increase the Japanese war effort.
What was the morality of using the atomic bomb?
The morality presented was that dropping the bomb would end the war and save more lives because the U.S. would not have to invade and fight through the cities there to subdue it. == The standard answer (and arguably most true) is that using the Atomic Bomb stopped the Japanese from fighting a protracted war for Japan. While a horrific thing to be sure the loss of life encountered by the dropping of 2 bombs was probably less than what would have been experienced in an island to island, to the last man war of attrition. Hindsight is always 20/20 and people can say all day that we shouldn't have done it, but the reality is that we did it and it can't be taken back. The other thing to consider here is that we warned Japan repeatedly that we were in possession of a weapon that would change the very face of war as we knew it, and that we were prepared to use it. The Japanese told the US to get bent, basically, and even after we dropped the first bomb they refused to surrender. I guess when you get down to brass tacks there really is nothing moral about war. It is a terrible thing to undertake and I think that the decision to use atomic weapons was the best option we had at the time. ==
Was the decision to drop the atomic bombs on japan good or bad?
WW2 was the world's last TOTAL WAR. Total war meaning fought to win with any weapons available (minus Chemical Weapons by treaty signed after WW1). The Atomic Bombings brought man into the atomic age (1945). Without the bombings there would have been no Cold War, no Atomic Age, no end to WW2 without millions of more deaths (for both sides). Only one nation had atomic weapons at the time of the atomic bombings; so it was a good idea. If other nations had the "bomb" it would have been a bad idea. Then it would have been a nuclear war. Such as it was when the Soviets (Russians) tested their first atomic bomb in 1949. Atomic Weapons created a COLD WAR (A stand-off between atomic armed countries). Total wars CANNOT be fought any longer without risking total destruction to both sides, referred to as, "Mutually Assured Destruction" during the cold war (1945-1990). Only conventional wars, not involving NUCLEAR WEAPONS (called "Limited Wars") could be safely fought during the cold war.
Why did Harry Truman order the atomic bomb?
He was faced with the choice of using the Bomb or of ordering a conventional invasion of mainland Japan, which The Pentagon estimated would cost up to a million Allied lives. Because the number of casualties in the Far East had already been horrifically high, and because the Japanese military were known to be extremely cruel to their captors, he regarded the conventional option as unacceptable.
Why did admiral leahy feel the use of the atomic bomb on japan was unnecessary?
He believed that continued bombing attacks and a naval blockade would
finish off all Japenese resistance. He also objected to the atomic bombs use on the grounds that other nations would develop the technology and
in some future conflict it would be used against the US. He also had moral
objections that our use of such a weapon made the US "common to the
barbarians of the Dark Ages".
Who dropped the first atomic bomb and where was it dropped?
It was dropped by the United States by orders of President Truman over Hiroshima, Japan.
Why did the US drop the atomic bombs on Hiroshima and Nagasaki instead of Tokyo?
If they had been detonated on the ground then a very large part of their explosive energy would have been directed to just making a large hole in the ground. By setting them off about 1000 feet in the air, all that energy was directed into destroying things.
Why was the atomic bomb project called the Manhattan project?
The U.S government project, named for the Manhattan Engineer District that produced the first nuclear weapons in Worl War 2.
Who is the physicist who directed the first atomic bomb?
Julius Robert Oppenheimer was the scientific director of the Manhattan Project, the World War II effort to develop the first nuclear weapons at the secret Los Alamos National Laboratory in New Mexico. For this reason he is remembered as 'The Father of the Atomic Bomb'.
Why is Hydrogen bomb more destructive than atom bomb?
A hydrogen bomb is more destructive than an atomic bomb because it has hydrogen. Hydrogen is highly flammable, and if a hydrogen bomb exploded with enough force and just enough fire, a huge wide area of a fiery explosion will occur. This is more destructive than the atomic bomb. Fire basically engulfs everything and destroys all in its path, making for an effective bomb.

Wrong!
Hydrogen does not burn in a hydrogen bomb, it fuses releasing atomic energy too. This fusion reaction is over in microseconds, much faster than combustion can start; also it reaches temperatures in the tens of millions of degrees, much hotter than any chemical fire or fission bomb. The reason a fusion bomb is usually more destructive than a fission bomb is the fusion bomb has no upper limit on yield, the fission bomb cannot be built with a yield over 1 megaton. One can just keep adding fusion stages until you get the desired yield.
Who ordered the dropping of atomic bomb on Japan in World War 2?
The actual order was issued by the Joint Chiefs of Staff of the War Department [now called the Defense Department], although the authorization of the President was required before they could issue the order.
That is true, but the official order and authorization was issued by President Truman, but he did not know anything about the bomb until after Roosevelt died.
How many Americans died in the Pacific Theater before the atomic bomb was dropped on Japan?
Asia-Pacific 108,504:
- Army ground forces 41,592
- United States Air Forces 15,694
- Navy/Coast Guard 31,485
- Marine Corps 19,733
- Unidentified Theaters- Army 39
What country did America drop two atomic bombs on?
Nuclear weapons have only been used in combat on Japan.
Why would Franklin D. Roosevelt had given the order to drop atomic bombs on Hiroshima?
==Answer 1== Since Roosevelt died before being confronted with that decision, ANY ANSWER will be pure speculation and opinion. However, based on what I know of FDR from many historical sources, I suspect that he, like most, would have not wanted to, but I think, would most certainly have come to the same conclusion as did Truman.j3h.
How fast can the atomic bomb go?
The bomber that dropped it was cruising at about 425 miles per hour. the explosion itself would expand at a rate of one mile per second or 3600 MPH as do all atmospheric explosions. the interval between the flash and the bang determines range. ( this would not work with an underground nuclear test shot, obviously. what a morbid question, but ballistics are influenced by atmospheric constants of the speeds of Light and sound, the latter being Mach"s constant- 760 MPH at sea level.
What country was the first to get the atomic bomb?
In 1978 a Magic decrypt of a diplomatic signal from the Japanese embassy in Stockholm reported the astonishing news to Tokyo on 12 December 1944 that Nazi Germany had the Atomic bomb and had already used it in June 1944 south of Kursk to wipe out the Soviet 19th Division (19th Voreneyzh Rifles Div ?) and later repeated it's use in the Crimea.
It is impossible to dismiss as a hoax because it was a secret encyphered radio transmission which the Americans secretly de-cyphered and copied. The signal is held in US National Archives. It's text reads:
" Part 1
This bomb is revolutionary in its results, and will completely upset all ordinary precepts of warfare hitherto established. I am sending you, in one group, all those reports on what is called the atom-splitting bomb. It is a fact that in June of 1943, the German Army tried out an utterly new type of weapon against the Russians at a location 150 kilometers southeast of Kursk. Although it was the entire 19th Infantry Regiment of the Russians which was thus attacked, only a few bombs (each round up to 5 kilograms) sufficed to utterly wipe them out to the last man.
Part 2.
The following is according to a statement by Lieutenant-Colonel UE [ ISHIWARA ]
KENJI, advisor to the attaché in Hungary and formerly in this country, who by chance saw the actual scene immediately after the above took place:
"All the men and the horses the explosion of the shells were
charred black and even their ammunition had all been detonated."
Moreover, it is a fact that the same type of war material was tried out in the Crimea,
too. At that time the Russians claimed that this was poison-gas, and protested that if
Germany were ever again to use it, Russia, too, would use poison-gas.
Part 3.
There is also the fact that recently in London - in the period between October
and the 15th of November - the loss of life and the damage to business buildings
through fires of unknown origin was great. It is clear, judging especially by the
articles about a new weapon of this type, which have appeared from time to time
recently in British and American magazines - that even our enemy has already begun
to study this type. To generalize on the basis of all these reports: I am convinced that the most important technical advance in the present great war is in the realization of the atom-splitting bomb. Therefore, the central authorities are planning, through research on this type of weapon, to speed up the matter of rendering the weapon practical. And for my part, I
am convinced of the necessity for taking urgent steps to effect this end.
Part 4.
The following are the facts I have learned regarding its technical data:
Recently the British authorities warned their people of the possibility that they might
undergo attacks by German atom-splitting bombs. The American military authorities have likewise warned that the American east coast might be the area chosen for a blind attack by some sort of flying bomb. It was called the German V-3. To be specific, this device is based on the principle of the explosion of the nuclei of the atoms in heavy hydrogen derived from heavy water. (Germany has a large plant in the vicinity of Rjukan, Norway, which has from time to time been bombed by English planes.). Naturally, there have been plenty of examples even before this of successful attempts at smashing individual atoms. However, as far as the demonstration of any practical results is concerned, they seem not to have been able to split large numbers of atoms in a single group. That is, they require for the splitting of each single atom a force that will disintegrate the electron orbit.
Part 5.
as far as the demonstration of any practical results is concerned, they seem not to have been able to split large numbers of atoms in a single group. That is, they require for the splitting of each single atom a force that will disintegrate the electron orbit. On the other hand, the stuff that the Germans are using has, apparently, a very much greater specific gravity than anything heretofore used. In this connection, allusions have been made to SIRIUS and stars of the "White Dwarf" group. (Their specific gravity is 1 thousand, and the weight of one cubic inch is 1 ton.) In general, atoms cannot be compressed into the nuclear density. However, the terrific pressures and extremes of temperature in the "White Dwarfs" cause the bursting of the atoms; and
Part 6.
There are, moreover, radiations from the exterior of these stars composed of what is left of the atoms which are only the nuclei, very small in volume. According to the English newspaper accounts, the German atom- splitting device is the NEUMAN disintegrator. Enormous energy is directed into the central part of the atom and this generates at atomic pressure of several tons of thousands of tons (sic) per square inch. This device can split the relatively unstable atoms of such elements as uranium. Moreover, it brings into being a store of explosive atomic energy. A-GENSHI HAKAI DAN. That is, a bomb deriving its force from the release of atomic energy."
The conventional view of history however is that America was first to use nuclear weapons in War against Hiroshima on 6 August 1945
How did the Soviet Union acquire the atomic bomb?
They built their own based on information acquired through espionage from people on the manhattan project or connected to them such as Klaus Fuchs, Ted Hall, and the Rosenbergs among others.
There has been no evidence presented at all to prove that Oppenheimer supplied the Soviet Union with information about the atomic bomb.
