Answer . Lists of Japanese cities eligible to bet A-bomb targets were made up by Leslie Groves for the Secretary of War Stimson. Groves wanted cities that had not been heavily damaged by U.S. B29 raids so that the level of damage created by the A-bomb could be accurately studied. Stimson wanted t…o spare cities that had great cultural value (that dropped Kyoto off the list). Hiroshima & Nagasaki fit the above categories and had some token military facilities to help validate them being used as targets.. (MORE)
Because of their shapes. In the plutonium bomb the plutonium was inthe shape of a sphere and shaped explosive charges were placedaround it to drive the sphere into itself and start the nuclearreaction. This configuration gave the bomb a stubby, rounded shape,hence the name Fat Man . In the uranium …bomb on the otherhand, most of the uranuim was formed into a cylinder with a hole inone end. An additional plug of uranium was fired down a smooth borecannon barrel into that hole, thus producing critical mass andstarting the chain reaction. That bomb looked long and slim incomparison with the other so it was called Little Boy . Athird bomb design called Thin Man had been designed usingthe gun assembly mechanism (like Little Boy used) but withplutonium, it was roughly twice as long as Little Boy and muchthinner but the design was found to be unworkable so it wasabandoned and work on Fat Man begun to make use of plutonium.

Japan would not surrender after the first one was dropped, sothey dropped the second one. . By dropping the second so quickly, the Americans bluffed theJapanese into thinking the Americans had a huge supply of theseweapons. . Had they known that just one or two more were ready, the Japanesemight… have gone ahead and toughed it out for another year. Thiswould have resulted in even more catastrophic results for theJapanese people than actually occurred. Many were nearly starvingalready. Another year of fighting would have killed millions justfrom lack of food. Additionally ground fighting would have startedand, as in Germany, that was much more destructive than the aerialbombardment. . As awful as they were, the bombs were a necessity to end the warquickly and in the end saved many Japanese lives and muchproperty. . The US had 1 ready to drop in late august and a productionschedule and operating facilities to drop 20 more before the end of1945. These took time to make and they were to be used asquickly as they were made . . The US was just lucky to have had two different ways to makethem that produced their first bombs at about the same time (BTW,there were no more plans to make anymore Little Boy bombs in 1945as they wasted too much uranium). . Also had the Japanese not surrendered and the invasion had began itis virtually certain that the US would have used chemical weaponsin Japan during the invasion. I am sure that Truman saw the atomicbomb as a possible way to avoid using chemical weapons (which is aviolation of the Geneva Protocol). . The Japanese military actually had a plan to continue the war foranother 10 years at the cost of 100 million Japanese (more than thepopulation of the main islands in 1941), which while they wouldlose in the end anyway. The US would be so tired of the war thatJapan (with a residual population left of under 3 million) Japancould then dictate all the terms and conditions of theirsurrender to the US. (MORE)
Hundreds of thousands of bombs were dropped on Japan. Only twoatomic bombs were dropped. As in all warfare, bombing is designedto destroy the enemy's ability to resist.
Answer . The simpelest answer is that the US had two bombs available at that time in history and was seeking the fastest way to end WW2 without invading Japan and risking the tremendous causalties such actions might produce.
More than 100,000 people were instantly killed . Each atomic bombing resulted in deaths proportional to a typical nightly 1000 plane conventional firebombing raid. The amount of damage and deaths were not unusual, just the fact that a thousand planes were not needed to do it.
Not only 2 nuclear bombs havebeen dropped. Lots have been dropped to test the effect. However, only 2 has been dropped in war. They were dropped in Hiroshima and Nagasaki (both Japanese cities).
It speeded up the end of the war, thereby speeding the recovery from the wars damages. By ending the war, a difficult and costly invasion was avoided and that probably saved lives on both sides.
A MK-I uranium gun bomb, codenamed Little Boy . A MK-III plutonium implosion bomb, codenamed Fat Man 21 more implosion bombs were scheduled for production and delivery in 1945 had Japan not surrendered.
Little boy was dropped on Hiroshima and Fat man was dropped on Nagasaki a few days later forcing Japan to surrender.
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 th…e bombings- if you include these as well, the total death rate reaches about half a million. (MORE)
Fat Man (Nagasaki) and Little Boy (Hiroshima) Fat Man was the second bomb dropped. Little Boy was first.
Japan did not agree to surrender unconditionally and Truman then consulted with his advisers and decided to use the new weapon on Hiroshima and Nagasaki.
Enola Gay dropped Little Boy over Hiroshima, killing 70,000-130,000 instantly. Bockscar dropped Fat man on Nagasaki killing 45,000. "Little Boy" (Hiroshima )on Monday, August 6, 1945, "Fat Man"(Nagasaki)on August 9.
Harry S. Truman (May 8, 1884 - December 26, 1972) was the thirty-third President of the United States (1945-1953).. Truman was quickly briefed on the Manhattan Project and authorized use of atomic weapons against the Japanese in August 1945, after Japan did not accept  the Potsdam De…claration .  The atomic bombings that followed were the first, and so far only, combat use of nuclear weapons .. On the morning of August 6, 1945, the B-29 bomber Enola Gay dropped an atomic bomb on Hiroshima .  Two days later, having heard nothing from the Japanese government, the U.S. military proceeded with its plans to drop a second atomic bomb. On August 9, Nagasaki was also devastated.  Truman received news of the bombing while aboard the heavy cruiser USS Augusta on his way back to the U.S. after the Potsdam Conference . The Japanese agreed to surrender on August 14 .  (MORE)
Hiroshima (Aug. 6, 1945): . 70,000 die instantly . After two days, the approximate total number of deaths recorded was 180,000 (this does not include deaths from radiation) Nagasaki (Aug. 9, 1945): . 70,000 die total
The nuclear bomb was first partially developed by the Germans.. British Intel located a number of documents and were able to produce a small scale device and tested it in a Cornwall Mine.. The US were given details of the British device and with the assistance of the UK and two German scientists, …created the Two devices that were to be dropped on the Japs.. So, the US, England and Germany were actually involved. (MORE)
Atomic weapons were not invented in the first world war. No cities had atomic bombs dropped on them.
Hiroshima and Nagasaki, bombings of (1945). The atomic bombing of the Japanese cities of Hiroshima and Nagasaki in August 1945 represents arguably the most important and most sinister development in warfare in the 20th century. THOUGH; more people died in the conventional bombing of Tokyo, the a…tomic bombings were significant because they caused death on a huge scale from one bomb dropped by one plane. Hiroshima and Nagasaki remain potent symbols and a sterile controversy over the use of the atomic weapons continues. In purely military terms the bombs proved decisive in persuading the Japanese government to think the unthinkable and accept defeat. BUT: According to most estimates, the immediate effects of the blast killed approximately 70,000 people in Hiroshima. Estimates of total deaths by the end of 1945 from burns, radiation and related disease, the effects of which were aggravated by lack of medical resources, range from 90,000 to 140,000. Some estimates state up to 200,000 had died by 1950, due to cancer and other long-term effects .Actually, from 1950 to 1990, roughly 9% of the cancer and leukemia deaths among bomb survivors was due to radiation from the bombs , the statistical excess being estimated to 89 leukemia and 339 solid cancers. It was after the two bombs dropped on Japan that as the two cities were destroyed , Japan decided that it would be best to surrender , as we know Japan would fight for years otherwise. (MORE)
Aug 6, '45 - Hiroshima and Aug 9 - Nagasaki Not dropped by US troops but by USAAF ( Army Air Forces ) bombers.
The only country to be attacked with atomic weapons during World War II was Japan.
3 days: August 6 to August 9. A third bomb was ready and in San Francisco on August 18 and couldprobably have been dropped on or about August 25 had the Japanesenot signaled on August 14 their intention to surrender. In total the US had facilities and scheduled production to make 23atomic bombs an…d drop them on Japan (only the first 2 were actuallyused) in 1945. With the war over by September these plans weresignificantly scaled back and some of the plants shutdown forrepairs due to unanticipated problems. This meant that by the endof Operation Crossroads in the summer of 1946 the US had only builta total of 9 atomic bombs, 5 of which had been detonated leavingonly 4 in the stockpile. (MORE)
The name of the two cities the atom bombs were dropped on in World War 2 were called Hiroshima and Nagasaki, Japan.
He surrendered. There were plots by the officer corps to keep fighting engineered against the emperor, but he prevailed.
It was actually the lower yield MK-I Little boy bombdropped on Hiroshima that did more damage. The higher yield MK-III Fatman bomb was accidentallydropped much further from its target (almost 2 miles away) and theblast wave was contained by the surrounding hills.
The authorizations were all made in May 1945 , when theTarget List was prepared and the orders to "use the atomic bombs onJapan as they become available". As the Trinity Test had not yetbeen done, only the simpler MK-I "Little Boy" type atomic bomb wascertain to work. It was unlikely that more than… about 6 of thesecould be made before the end of 1945. Following the successful Trinity Test the availability of MK-III"Fatman" type bombs (which though more complex could bemanufactured in large numbers, as they needed much less fissilematerial) it was decided to cancel further production of the MK-Iat the one already finished and produce only MK-III atomic bombs.This allowed the number of bombs to increase from about 6 to 23that could be made before the end of 1945. The only actual order that Truman gave about atomic bombsduring the war was to cancel the already existing orders touse them, once Japan indicated they would surrender. The fact thatthey surrendered after only the first two probably caughtTruman and many others completely by surprise. Based on priorexperience most military leaders and US government officialssincerely believed it would be necessary for more than 90% of theJapanese population to die before the country would be unable tocontinue fighting (and US was willing to do whatever was needed tobring this about).

Hiroshima became the first city in history destroyed by a nuclear weapon when the United States of America dropped an atomic bomb on it at 8:15am on August 6, 1945, near the end of World War II
It got Emperor Hirohito to finally surrender. Hirohito would have kept on fighting until the entire Japanese race died had he not realized the US could have wiped them out completely and he would have broken his vow to protect and preserve his family throne. . The bombs cause the deaths of around… 300,000 initially and later on. An invasion by both Russia and the USA would have resulted in the deaths of many millions of Russians, Americans, Australians, Japanese and whoever else. . The Bombs sent the world into the atomic age (both good and bad, mostly good for the world of medicine). . We gained a friend for many decades once the Japanese surrendered after the bombs were dropped. . We now have US and Japanese scientist working together not only to monitor and resolve problems from radiation but also to work on many other scientific solutions. . Japan came out of the agricultural age once they found out the US had made the atomic bomb before they did and they realized they were far behind the rest of the world in technological advances.

Because they wanted the Japanese to give up, but they didn't even though Germany had so they bombed Hiroshima.
The bombing is still, over 65 years after it happened, a prettycontroversial decision. The official answer is that PresidentTruman ordered the bombings to end the war quickly and decisively. In the Allied conferences near the end of the war, it was decidedthat the Axis nations needed to fully surre…nder "unconditionally"in order to prevent another war, as happened after World War I (inthat war, Germany didn't surrender unconditionally- they signed anarmistice and eventually negotiated a treaty. Twenty years later,Germany started an even bigger war). Germany was defeated andsurrendered in early May 1945, but Japan kept fighting. The Allies were winning the war with Japan, but it was bogging downinto a costly, bloody affair. Some examples of the bloodshed- inearly 1945, the Allies had captured the island of Iwo Jima, a tinyisland not far from Japan, at the cost of over 26,000 casualties.Then in the summer of 1945, the Allies suffered over 80,000casualties capturing Okinawa, another tiny island not far fromJapan. So as the Allies closed in on the Japanese home islands, thefighting became fiercer. The Allies were drawing up plans for aninvasion of Japan- since Japan showed no signs of surrendering- andall of the plans predicted massive destruction and millions ofcasualties. Truman and supporters of the decision believe that byunleashing nuclear weapons on Japan, they caused Japan to surrendermore quickly. It's controversial, as mentioned earlier, because it's not totallyclear that it had the intended effect (other factors came intoplay, such as the Soviet Union's declaration of war on Japan), theAllies' role in indirectly encouraging Japan to fight on (via thePotsdam Declaration), and the serious ethical questions regardingannihilating hundreds of thousands of people in the blink of aneye. That's a debate that has raged since before the bombs evenfell. The US did not decide to drop two atomic bombs onJapan, the decision was to drop as many as needed to force Japan tosurrender and we had production plans and facilities to manufactureand drop a total of twenty three atomicbombs on Japan in 1945 alone. It was the Japanese that decidedto surrender and stop it at two bombs . Another thing to remember is that after meeting the strongresistance by the Japanese at the last few islands, the US beganstockpiling chemical weapons (e.g. several types of nervegases, mustard gas, phosgene gas) in preparation for use in theinvasion of Japan if similar resistance was encountered. Evenbefore the decision was made to use the atomic bomb, the US wasalready 100% committed to the use of these chemical weapons.However Japan had already used chemical weapons in China andelsewhere and the Allies had declared such use by Japan to be War Crimes . What might our use of chemical weapons againstJapan be seen as? The atomic bomb was seen as a way out of thisdilemma. (MORE)
The MK-I Little Boy had about 100 pounds of 80% enriched uranium and about 4 tons of other stuff needed to make that explode. The MK-III Fat Man had about 15 pounds of plutonium and about 5 tons of other stuff needed to make that explode.
The two main sides during WW2 were: . use to attack Japan . demonstrated to Japan Of those advocating for a demonstration there were two main sides: . dropping the bomb over the ocean just off Japan's coast withinsight of a major city, e.g. Tokyo . setting up a tower shot like trinity on an …island near Japanand inviting the Japanese leadership and military to come witnessit Both of these were dismissed because it was believed the Japanesewould either dismiss the whole thing as some kind of nonreplicabletrick or might be able to attack and disable/destroy the device. Thus the only viable option, regardless of anyone's opinion was actual use in combat. Another thing to realize is that when the landing and invasion ofJapan was to begin a couple months later that the US was already 100% committed to full scale use of chemicalweapons ; including several types of nerve gas,phosgene, and mustard gas if during that invasion the Japanesefought as they did on many of the last islands (e.g. Okinawa). Theeffects of such weapons are every bit as horrifying as those ofatomic bombs and less predictable/controllable. Also the Japanesehad already used such weapons in China and other places, and we haddeclared these Japanese uses to be war crimes . Use ofatomic bombs to force Japan to surrender before we would be forcedto use our stocks of chemical weapons was seen as the lesser of twoevils. About the only person during WW2 that would have completely opposeduse of the atomic bomb against Japan was AlbertEinstein and he did not even know that we possessed it atthat time as he had never worked on the project. Einstein was a pacifist and refused all warwork of any kind on principles. (MORE)
The two bombs dropped on Hiroshima and Nagasaki were named "Little Boy" and "Fat Man" respectively.
reason-1. USA (and its allied forces) wanted to punish Japan andJapan to be capitulized; reason-2 to show USA has acheived a realexplodable atomic bomb reason-3 USA to see the after effects of bomb blast 2nd Answer: None of the above is true. The two bombs were dropped to preventmass death when the… allies invaded Japan (because she would notsurrender). In other words, to force Japan to surrender. They didnot surrender after the first bomb was dropped on Hiroshima, and asecond bomb was dropped on Nagasaki. At this point a huge allied invasion force was within two weeks ofinvading Japan. Huge numbers of allied and Japanese military wouldhave died had the invasion taken place, along with millions ofJapanese citizens. Secondly, a number of Japanese cities hadendured thousands of incendiary bombs being dropped. This wascalled fire bombing. Tokyo was the main target, and it was nearlydestroyed from the ensuing fires. Many more military and civilianswere killed and injured than by the two bombs. After the war ended, a number of Japanese Navy higher-ups statedthat the dropping of the two bombs saved millions of lives, andthey were happy that their country was never invaded militarily. (MORE)
hiroshima , im not sure about the other one but im 100% sure hiroshima was one of them
one was the pearl harbor bombing, another was that the Japanese were allies with the Germans
Put it like this. A couple hundred thousand had died in Hiroshima and Nagasaki. If the United States and her allies in the Pacific had invaded the Japanese home islands, it would've cost both sides around 1 Million Deaths each. Your call. :)
The Untied States of America dropped the first atomic bomb on Nagasaki. The first bomb was dropped on Hiroshima.
Harry S. Truman authorized the bombing of Hiroshima and Nagasaki. During the years 1945 and 1953. August 6, 1945.
mostly to reduce the chance the japanese would attack the lightly armed and unescorted bombers delivering the bombs.
Because a mainland invasion would have been very costly, and the US wanted to test their new toy.
It was an act of war. The Japanese bombed Pearl Harbor first, without any warning of hostility towards them.
The heavy losses on both sides if a land invasion was required to get the Japanese to surrender. After the first bomb was dropped most of the Japanese military wanted to continue the war.
The Little Boy atomic bomb, a uranium gun type weapon, was dropped on Hiroshima by the B-29 Enola Gay. The Fat Man, an implosion type with a plutonium core, was dropped on Nagasaki by the B-29 Boxcar.
The casualties for the atomic bombs dropped onto Japan was 215,000dead and 1,900 more dead after the war. The majority which diedduring post war was mainly due to solid cancer, it was reportedthat 1,700 died from solid and 200 died from Leukemia due toexposed of radiation from the atomic bomb drops …in 1945.

On August 6th and 9th 1945, the US dropped 2 atomic bombs onto Japan which caused just over 200,000 people dead and many more scared from life. The 2 cities which the atomic bombs were dropped on were Hiroshima and Nagasaki.
one of the atomic bombs blew up a town; which was heavily populated, and the other completely whipped out a island.
About the same as happened in two of the 500 to 1000 planeconventional firebombing raids, several of which happened every night . This came to about 100,000 each. Had thesurrender not happened both the conventional and atomic bombingswould have continued until it did. The US had plans and producti…onfacilities ready to drop 21 more atomic bombs on Japan before theend of 1945 and could have dropped many times that in followingyears if necessary. However the important thing to remember was that the conventionalfirebombing raids already in progress were killing more Japanese every night than the two atomic bombs killed in total!Even had all 23 atomic bombs scheduled to be dropped in 1945 beenused, conventional bombing and the invasion (which almost certainlywould have involved US use of chemicalweapons too) would have caused many more deaths thanthe atomic bombs could.
