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.

Why was the invention of atomic bombs a turning point in history?
it was the first time a real weapon of mass destruction was used in a major populated area. it was the first and so far only time a nuclear weapon has been used. it also stopped the war from lasting who nows how much longer.
AnswerRather obviously, viewed from the vantage point of our present time, the use of atomic weapons hearlded the potential for the total destruction of earth.It can be argued that the use of atomic weapons against Japan really was little comprehended at the time by virtually anyone. Even today, it is fair to say that the majority of people really have little actual comprehension of the immediate destructive effects of atomic weapons, let alone thermonuclear hydrogen bombs.
Reguardless, the important aspect is that the potential for unheard of worldwide destruction was realized in the demonstrated use of the atomic bombs.But it wasn't just the atomic bomb which revolutionized the concepts of military science, it was also the revolutionary advances made by the Nazis in rocket technology that truly created a "True Turning Point" in the history ofthe world.
Atomic bombs were still just bombs, they had to still be delivered to their intended targets. J.F.C. Fuller, a military theorist, contended that the principle primary weapon in any time was the one which had the greatest reach.This concept has been validated as the predominate and most significant principle in the analysis of warfare. In short, if an enemy can be attacked with a weapon of such range that it is impossible for them to strike back the ultimate conclussion is obvious defeat of that enemy. Thus, it is the employment of the strategic bomber and the aircraft carrier which dominate the allied actions in responding to the aggressors. The tank, combined with revolutionized tactical organization in its' employment, such as the use of specialized aircraft acting in the field artillery mode, and supported by mechanized infantry, enabled the Germans to essentially "Out Think" the Allied Forces which oppossed them. Ironic to think that these ideas were the actual work of a British Officer, J.F.C. Fuller. The German successes demonstrated that victory comes about as a result of doing things in a new way which upsets established principles. Not only that, but also the employment of a mechanized organization which, though tactical, still had the decisive effect of speeding up actions. In effect the Nazis speed up time, or were working in a time scale which was quite beyond the abilities of the Allies to deal with. A result of their more primitive defense plans which utterly failed to deal with the implications of developing technology. Thus, the "Time Factor" is a critical element in understanding not just defeat, but the psychological aspect of defeat via potential use of atomic weapons: Their use results in immediate and total destruction.
The Atomic Bomb and the V2 Rocket were the true technological devices which made a turning point in the history of the world. It is the legacy of these primitive devices which haunt our lives and stir our private innermost fears.The fear of Nuclear Armagedon.
Why was the usage of the atomic bomb controversial?
It is true the bombings end the war and did collapse Japan's means to make war ever again but the fact is that there were so many civilians casualties that a controversy emerged and even today, people are talking about it.
What element was used in atomic bombs?
The first atomic bomb used against mankind was dropped over Hiroshima, Japan on August 6, 1945. It's code name was little boy and it used Uranium as fuel. The second bomb was dropped over Nagasaki, Japan on august 9, 1495. It,s code name was fat man and it used Plutonium as fuel.
What radiation do atomic bombs give of?
The radiation levels of atomic bombs vary according to the amount of radioactive elements put into the bombs or missiles and if they are actually used. Once the radioactive matter is inside the bomb housing the radiation levels are negligible but once one of the nuclear bombs is used then the variables come into play. (see related link below to see how complex it is)
Consider this: the atomic bombs dropped on Japan in 1945 are 1/10th the killing power of today's nuclear missiles. If one modern nuclear missile were to be used today the bomb would be able to kill about a third of the world with the initial bomb blast and radiation fallout.
The radiation level after Hiroshima and Nagasaki was not really measured until after the US occupied Japan. The Japanese leaders did not really understand the radiation fallout and poisonous danger and they did not use radiation detectors right after the blast. It is rumored the radiation levels were 100 times today's acceptable levels of radiation.
What were the nicknames of the two atomic bombs dropped on Japan in World War 2?
the one dropped on hiroshima (uranium) was called little boy. it was 3 metres long and thin.
The one dropped on nagasaki was call fat man. this one contained plutonium and was 4 metres long and much rounder.
The plane was callled the enola gay (B-29) and the pilot was callled tibbins.
What was the name of the plane that dropped the atomic bombs in Japan?
There were two planes which dropped the weapons. The Enola Gay is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb. The bomb, code-named "Little Boy", was targeted at the city ofHiroshima, Japan, and caused unprecedented destruction. And the Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second - and last - nuclear attack in history.
What are some of the affects of the atomic bombs dropped on japan?
the atomic bomb was dropped on civilians not military and killed any where between 75000-250000 people when it landed, another thing is mostlikely today there is still heavy radition on th spot the bomb was dropped. one other it could have done is with the sudden increase of the test bomb, fatboy, and fatman could have completely destoyed the earths atmosphere.
What was the name of the first atomic bomb that US dropped on Japan?
The first bomb that was dropped for war purposes was a uranium bomb code named "Little Boy" that was dropped on Aug. 6, 1945 on Hiroshima and the second was code named "Fat Man" and it was a plutonium bomb dropped on Aug. 9, 1945 on Nagasaki. The was ended only 1 day after the second bomb was dropped. The bombs caused Japan to surrender. Both a-bombs (atomic bombs) caused about 128,000 people to die and over 120, 000 people suffered from radiation sickness and cancer. So much suffering led many of them to die shortly after.
What was life like in the US after the atomic bomb had been dropped?
There was an initial sense of euphoria and invincibility. And then the question sank home, what if someone else cracks the atomic weapons secrets. Fear and a need for self defense against such a scenario was immediate.
The top secret program to build a atomic bomb was called what?
There were a number of top secret programs to build an atomic bomb. If you mean the secret plan of the US, it was called the Manhattan Project.

How did the experiences of Iwo Jima and Okinawa affect the Allied decision to drop the atomic bomb?
Okinawa was launched to confirm the general idea of how the final battle for the main islands of Japan would be fought. After the success of the creation of the A-bomb, the U.S. figured that the bomb would be a better way to finally end the war rather than an invasion. Truman left instructions that the bomb wasn't actually going to be used until after the Allies agreed and issued a declaration. The declaration (Potsdam Decl.) called for an "unconditional surrender" from Japan, however, Japan very much refused. The declaration stated that if Japan did refuse to surrender, more destruction (following the Battle of Okinawa) would continue. This destruction was the bombing on Japan (Hiroshima and Nagasaki).
What two atomic bombs did the US drop on Japan?
The planes were B29's, also known as "Super-fortress" since they were larger than the workhorse bomber of WW2, the "Flying Fortress" or B17. The names of the two that dropped the bombs were "Enola Gay" and "BoxCar".
What lead to the dropping of the atomic bomb on Hiroshima and Nagasaki?
The bombing of Pearl Harbor and the development of the atomic bomb led up to the bombings of Hiroshima and Nagasaki. The bombing of Pearl Harbor and the development of the atomic bomb led up to the bombings of Hiroshima and Nagasaki.
How much people died after the atomic bomb?
On August 6 and 9, 1945, the cities of Hiroshima and Nagasaki were destroyed by the first atomic bombs used in warfare. The first atomic bomb ever to be used in a military operation was dropped on the city of Hiroshima, Japan On August 6, 1945 at 8:16:02 a.m. Hiroshima time. The bomb, affectionately named "Little Boy," exploded 1,900 feet above the courtyard of Shima Hospital, with a force equivalent to 12,500 tons of TNT. By the end of 1945, 140,000 people had died as a direct result of the bombing. Within the following five years, another 60,000 would die of bomb-related causes.
-
The bomb killed men, women, and children indiscriminately. It killed both military personnel and civilians. Although the city produced military items and housed soldiers, it was not selected as a "purely military target" as President Truman had promised. There were six civilians in Hiroshima to every soldier.
-
The second bomb, called "Fat Man," exploded over Nagasaki, Japan, at 11:02 a.m. on August 9, 1945. It exploded at 1,650 feet with a force of 22,000 tons of TNT. 70,000 people lost their lives in Nagasaki by the end of 1945 due to the bombing. A total of 140,00 died within two weeks.
What two cities did the US drop the atomic bombs on to end the World War 2?
Hiroshima & Nagasaki

How long was the time span between the two atomic bomb droppings on Japan?
3 days: August 6 to August 9.
A third bomb was ready and in San Francisco on August 18 and could probably have been dropped on or about August 25 had the Japanese not signaled on August 14 their intention to surrender.
In total the US had facilities and scheduled production to make 23 atomic bombs and drop them on Japan (only the first 2 were actually used) in 1945. With the war over by September these plans were significantly scaled back and some of the plants shutdown for repairs due to unanticipated problems. This meant that by the end of Operation Crossroads in the summer of 1946 the US had only built a total of 9 atomic bombs, 5 of which had been detonated leaving only 4 in the stockpile.
What is the difference between a uranium bomb and a plutonium bomb?
The difference simply comes down to the fissile material (i.e. uranium or plutonium) used as fuel in the core (aka pit) of the bomb. There is also a third type that is less well known among the general public, the composite bomb which uses both uranium and plutonium together as fuel in the core (aka pit) of the bomb. In the composite bomb the uranium and plutonium could potentially be alloyed together, but are more likely (for metallurgical reasons) prepared as separately cast and machined nested shells that must be assembled to create the core (aka pit) of the bomb.
The secondary difference is the choice of rapid assembly mechanism used in the bomb to assemble a subcritical mass of fissile material into a supercritical mass of fissile material rapidly enough to avoid having stray neutrons initiate a chain reaction prematurely causing a fizzle. A fizzle may do no more than simply melt the bomb or may do as much as producing a yield of a few tons of TNT equivalent, but is unpredictable in effect and thus undesirable. There are several potential sources of stray neutrons ranging from cosmic rays to the materials of the bomb itself. If it were possible to obtain fissile materials that are isotopically pure (e.g. uranium-235, plutonium-239) the choice of rapid assembly mechanism would be a nonissue, but isotopic purity is simply an impossibility on the industrial scale that these materials must be produced. The issues with each fissile material are as follows:
- uranium - must be enriched from natural uranium and thus will always contain some uranium-238 which is not fissionable and captures the high speed neutrons needed to sustain the chain reaction. The usual form of weapons grade uranium used in US bombs is called oralloy and is 93.5% uranium-235 and 6.5% uranium-238. Neither of these isotopes has a significant probability of spontaneous fission and as the remaining uranium-238 actually poisons the chain reaction some, a uranium bomb can use either the gun or implosion rapid assembly mechanism with no risk of a fizzle happening.
- plutonium - must be produced in a reactor from uranium-238. Typical weapons grade plutonium as produced in reactors is about 93% plutonium-239, 6% plutonium-240, and 1% plutonium-241. Unfortunately the plutonium-240 isotope has a high enough probability of spontaneous fission that with this much of it in the fuel a bomb using the gun rapid assembly mechanism would certainly fizzle, leaving the implosion rapid assembly mechanism as the only viable choice for either a plutonium bomb or a composite bomb.
In summary the three types of atomic fission bombs differ as follows:
- uranium bomb - uranium fueled, may use either gun or implosion rapid assembly mechanism
- plutonium bomb - plutonium fueled, must use implosion rapid assembly mechanism
- composite bomb - uranium & plutonium fueled, must use implosion rapid assembly mechanism
What casualties did the Japanese suffer after the United States dropped two atomic bombs on Japan?
The casualties from the Hiroshima and Nagasaki bombs combined ran at about 250,000 killed immediately in the blast, with about 100,000 dying from radiation poisoning or injuries in the weeks and months that followed. Victims continued to perish of cancer or radiation poisoning for years following the bombings- if you include these as well, the total death rate reaches about half a million.
When was The Making of the Atomic Bomb created?
In September 1949, the first Russian bomb created a changed situation.
American bomber that dropped first atomic bomb?
The Enola Gay is the B-29 Superfortress bomber that dropped the first atomic bomb, code-named "Little Boy", to be used in war, by the United States Army Air Forces (USAAF) in the attack on Hiroshima, Japan on August 6, 1945, just before the end of World War II.
Did the people who invented the atomic bomb regret it?
Al Einstien was one of the inventers he said he did
Does America owe Japan an apology for using the atomic bomb?
No, however the US Military for decades has protected Japan from China, North Korea & the Soviet Union (now Russia). The US taxpayer has funded this.
