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.

Was the invention of the atomic bomb a accident?
No, the invention of the atomic bomb was not an accident. It was a deliberate and purposeful effort by scientists working on the Manhattan Project during World War II to develop a powerful weapon for the United States.
Was there a third atomic bomb in world war 2?
Yes, a third atomic bomb (a MK-III plutonium implosion assembly atomic bomb) kit had been built by Los Alamos during WW2. It had been shipped to San Francisco to be flown across the Pacific to Tinian for assembly and delivery to another Japanese city in late August. (Note: this kit was probably just the plutonium core, the polonium/beryllium initiator neutron source, and the uranium tamper as Tinian already seems to have had a dozen or more MK-III casings and explosive lens assembly kits stockpiled)
However as the Japanese had announced their intent to surrender on August 14 (while this bomb was still in transit), causing Truman to declare the end of the bombing of Japan, when this bomb arrived in San Francisco on August 18 it was immediately shipped back to Los Alamos, becoming the first atomic bomb in the US nuclear stockpile.
Had Japan not surrendered, the US had plans and the industrial capacity to produce and deliver 20 more MK-III type atomic bombs on Japan before the end of 1945:
- 3 in September
- 3 in October
- 7 in November
- 7 in December
How many Atomic Bombs did the U.S. Test?
More than a thousand in total.
Only one was tested during WW2.
Name the 2 cities that the USdropped atomic bombs on during World War 2?
hiroshima and nagasaki Japan
World War 2 nuclear weapons and atomic bombs?
All of the nuclear weapons available in WW2 were owned by the US and were pure fission atomic bombs:
- 'Gadget', MK-III prototype plutonium implosion assembly design, tested on a 100 foot tower at Trinity site, NM on July 16, 1945
- 'Little Boy', MK-I uranium gun assembly design, dropped by the B-29 Enola Gay on Hiroshima on August 6, 1945
- 'Fatman', MK-III plutonium implosion assembly design, dropped by the B-29 Bockscar on Nagasaki on August 9, 1945
- unnamed, MK-III plutonium implosion assembly design, arrived in San Francisco on August 18, 1945 to be flown to Tinian then dropped on Japan in late August 1945 but was returned to Los Alamos
Had the war not ended the US had plans and the industrial capacity to make 20 more atomic bombs and drop them on Japan:
- 3 MK-III plutonium implosion assembly design for September 1945
- 3 MK-III plutonium implosion assembly design for October 1945
- 7 modified MK-III composite plutonium/uranium implosion assembly design for November 1945
- 7 modified MK-III composite plutonium/uranium implosion assembly design for December 1945
Early planning had proposed additional production of the MK-I uranium gun assembly design, but after the successful July 16, 1945 Trinity test shot this was canceled, as it was decided the uranium could be used more efficiently in the modified MK-III composite plutonium/uranium core design. The 'Little Boy' was already in transit to Tinian aboard the Indianapolis at the time of this test, so it was used.
He worked with another chemist on the Manhattan Project, which led to the developement of the atomic bomb during WWII. He published a chemistry text book in 1960 and served as head of the chemistry department from 1969-1976
How was the first atomic bomb invented?
it was invented in ww2 when USA atomic bombed two cities in japan.Hiroshima and Nagasaki.this attack caused japan to surrender,and ww2 to be over
Were there any other Choices but to use the atomic bomb in World War 2?
Yes and we were committed to carrying out all of them, but the atomic bomb was used first and Japan surrendered so none of the other choices were needed, thus saving many millions of lives on both sides and ending the war at least a year sooner than anyone expected.
- a Japanese D-Day invasion landing
- chemical weapons attacks on Japan
- continued 1000 plane firebombing raids
- etc.
How was the atomic bomb a big advance in technology?
Mostly power because if you did not do what a country who possesed a atomic they threatened to blow you up
How many times has an atomic bomb been dropped?
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).
How does the atomic bomb affect foreign policy?
The first authoritative explanation of how and why it was decided to use the bomb came in February 1947 from Henry L. Stimson, wartime Secretary of War and the man who more than any other was responsible for advising the President in this matter. [3] This explana-

It didn't influence anything as it did not exist then.
What other possibilities were available other than the atomic bomb in World War 2?
- invasion - already planned
- chemical weapons - already planned, if Japan resisted as they had in last islands
- firebombing - already in progress
- let Japan keep everything they conquered - unacceptable
With what was planned the war would have lasted over a year longer (Japan actually had plans to try to stretch it out ten years and keep everything they had conquered even though they would have to ultimately surrender). Had chemical weapons been used against Japan this would have been the first time the US broke the Geneva Convention.
What happend in augest 4 1994?
actually August 6,1945, (if that is what you are looking for) US dropped the first atomic bomb on Hiroshima. Please excuse my spelling Hiroshima may be spelled wrong, or the end may be wrong. Pretty sure though about Hiroshima. The second bomb was dropped on Nagasaki. That one I'm going 2 have 2 take the chance of the spelling. (:
Did albert einstein help with the atomic bomb?
No, he had no involvement whatsoever with the project. Einstein was a pacifist and refused to work on any war related project himself.
His only involvement was to sign a letter written by Leo Szilard (the inventor of the atomic bomb) that was delivered to FDR warning of the danger if the Nazis built it and recommending starting a project.
Which country developed the atomic bomb?
We developed the first working atomic bomb but, GER. made up the idea.
Who drop the first atomic bomb?
"Who" is a relative question....."who" in the sense of what nation would be the United States which dropped the first atomic bomb on Hiroshima Japan August 6,1945. The "who" in the sense of what person - is usually accredited to Col. Paul Tibbets US Army Air Forces, the commander of the aircraft named Enola Gay (after his mother) which carried and dropped the bomb. The Japanese had been given a surrender ultimatum, and when there was no response from their government a second atomic bomb was dropped on the city of Nagasaki Japan on Aug 9. Both were devestating in death and destruction and they remain the only time in history nuclear weapons were used against a population. These were both nuclear fission weapons. The Hiroshima bomb was a uranium-based device, the Nagasaki bomb used plutonium (derived from uranium). There continues to this day much controversy as to the need for using these weapons since Japan had already seen most of its major cities fire-bombed with conventional pyrotechnic weapons causing equal devestation and killing and maiming as many people. Despite the terrible results of these two bombs, they are mere toys compared with the hydrogen-based (thermnuclear) weapons developed during the cold war which are hundreds of times more fearsome in their potential for destruction.
Who was the third country to have the atomic bomb?
The third country to be legally accused of having nuclear weapons was the United Kingdom, right after the United States and the Former Soviet Union.
What are Plutonium atomic bombs?
Plutonium was and still is used for atomic bombs. The atomic bombs you are talking about would be fat man and little boy. They were the two used to bomb Hiroshima and Nagasaki Many people were killed when the b-29 bomber dropped fat man.
When does the USSR get the Atomic bomb?
The Soviets tested their first A-Bomb in 1949; one year before the start of the Korean War (1950-1953).
