When did they decide to make the atomic bomb?
There were none, we only had the two. We had the materials to makea few more but they were not assembled and ready to use at thetime. A third unnamed MK-III Plutonium bomb core (counting the Gadget'score that was used in the Trinity Test) was shipped from Los Alamosa few days after the August 9 bomb…ing of Nagasaki and arrived inSan Francisco on August 18 where Colonel Tibbetts waited in a B-29to transport it across the Pacific to Tinian for eventual use onJapan in late August. However as the Japanese had indicated theirwillingness to surrender on August 14, president Truman made thedecision to have it returned to Los Alamos instead of using it. The production schedule and facilities allowed for themanufacturing and dropping of as many as 23 atomic bombs on Japanin 1945, limited mostly by the capacity of the Hanford reactors toproduce enough plutonium for 3 bombs per month. . August - 1 MK-I Uranium gun bomb (Little Boy) and 2 MK-IIIPlutonium implosion bombs (Fatman & unnamed) . September - 3 MK-III Plutonium implosion bombs (canceled),Hanford had probably already produced the Plutonium for 1 or 2 ofthese bombs by the middle of August but Los Alamos had probably notmanufactured cores from it before Truman canceled further atomicbombings . October - 3 MK-III Plutonium implosion bombs (canceled) . November - 7 MK-III Mod 1 Plutonium/Uranium composite coreimplosion bombs (canceled) . December - 7 MK-III Mod 1 Plutonium/Uranium composite coreimplosion bombs (canceled) It has been confirmed that more than 1 Plutonium bomb core existedat Los Alamos at the time of the Trinity Test (July 16) but whetherthat was just the one for Fatman or included the final August coreor maybe even some of the September cores cannot be determined fromunclassified documents. There may have been unassembled casings and kits of the nonnuclearcomponents of up to a dozen MK-III bombs already waiting on Tinianin August for their Plutonium cores. There had been several dozennonnuclear practice "pumpkin" bombs having the same dimensions andweight as the MK-III atomic bomb on Tinian and the 509th haddropped several on Japan through July and early August to practicefor the actual atomic bombings (as well as getting the Japaneseused to seeing missions of just 3 B-29s dropping only one bomb thatdemolished roughly one city block so that they might not considersuch flights as serious threats and scramble fighters against theactual early atomic bombing missions).

Trueman decided to drop the bomb on Japan because if they did an invasion, the United States would lose more men and Trueman did not want to take that chance.
Well, the official answer to this was that Truman figured, and probably rightly, that the Japanese would defend their homeland to the last living body and take as many Americans as they could with them. So, if he could get the Japanese to surrender based on the power of the A-Bomb (and he could prev…ent them from finding out that we actually had no more than the two that were dropped) he could save a lot of American lives.

Actually FDR made the decision to drop the atomic bomb prior to hisdeath, Truman did not even know of the atomic bomb at the time thisdecision was made. When he was informed of the atomic bomb afterFDR's death he only decided to continue all of FDR's decisions andpolicies without change. The Army Ai…r Forces implemented FDR'sdecision in an order to drop the bombs "as soon as they becameavailable". Truman's only actual decision on the use of the atomic bomb was to stop dropping them after the Japanese indicated theirwillingness to surrender on August 14. Truman continued his policy against the further use of atomic bombsby firing General MacArthur as soon as he proposed their use duringthe Korean War and replacing him with General Ridgway.

The ultimate decision to use the bomb or not lay with the President of the United States. The bomb was originally built to use on Germany. Once it was defeated they had to consider whether or not to use it on Japan to motivate them Japanese leaders to surrender and capitulate to the Potsdam Declarat…ion. Based on all the information provided to President Truman he chose to drop the bombs in the hopes of ending the war and avoid having millions of Japanese and Allied Forces killed in an mainland invasion. He had to weigh the advantage of murdering hundreds of thousand Japanese over the loss of millions people from Japan, the USA, Australia and other countries. He opted for the lesser of two evils. At the time the bombs were dropped they had no guarantee the bombs would even work or motivate the Japanese to surrender. The Allied Forces did not learn until years later that the Japanese were building the atomic bomb and had planned to use it on the United States. So It is likely the decision to drop the bombs prevented the Japanese from using them on the USA. ( Full Answer )

The emperor refused and the US dropped the second atomic bomb, after which Japan promptly surrendered. ( Full Answer )
Hitler did not have the atomic bomb and anyhow Japan was on his side. I cannot believe someone could ask such a question.

By the time development was complete on the atomic bomb, Germanyhad already surrendered leaving Japan as the only remaining enemyin the war.
It was a race between the US and Germany, although that part of the war was over before it was built. It was finished as an alternative to invading the home islands of Japan.
The US developed the first nuclear fission weapons (atomic bombs) during World War II as part of the Manhattan Project, a top-secret military program that saw several firsts in nuclear chain reaction experiments. Through the work of many international physicists and other experts, the US exploded th…e first a-bomb near Alamogordo, New Mexico on July 16, 1945. The following two bombs were used in August, 1945, against the Empire of Japan, destroying the cities of Hiroshima and Nagasaki. ( Full Answer )
Fear that Nazi Germany would make one first and win WW2 using it. It was not until after the end of the war that it was discovered that the German nuclear program was only a very low priority program directed mostly at reactor development.
To defend against the possibility of a Nazi atomic bomb, which ifGermany succeeded in making it Hitler would order it used againstBritain to force them to surrender. It was hoped the US mightcomplete the atomic bomb first, but if not then shortly after sothat Germany might also be attacked with them… in retaliation forattacking England. ( Full Answer )
The atomic bomb was first made and tested in Los Alamos, NM in 1945. This was during the final stages of World War II, although the war in Germany ended before any bombs were built. After the successful test at Los Alamos on July 16, 1945, two atomic bombs were manufactured and used against Japan. …The first was dropped on Hiroshima on August 6,1945, the second on Nagasaki on August 9, 1945. These were the only uses of atomic weapons in war. ( Full Answer )

Dropping the bomb brought the war to a quick end and prevented the need for a land invasion of Japan itself. While it's unfortunate that the two bombs killed tens of thousands of people, estimates for an invasion predicted somewhere around 1 million Allied casualties and 6-7 million Japanese dead or… wounded. ( Full Answer )
It depends upon your point of view. Some would argue that he did, in order to save the lives of a million Allied servicemen that would have been lost had mainland Japan been taken via conventional invasion. Others would say that he didn't, because of the horrendous nature of nuclear weapons and the …untold suffering that was inflicted upon an innocent civilian population.. My own feeling is that he was very wrong to permit the use of the two atomic bombs, because they caused such appalling suffering to the innocent- Japan could simply have been contained within it's own borders after it had been driven out of the nations it was occupying, until there was an internal coup or the economy collapsed. However, it has to be up to you to weigh up the arguments and reach your own decision. ( Full Answer )

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.
Many countries were all trying to build the bomb. The United States managed to become first and prevented the loss of far more lives then had they not been first.

Atomic bombs contain material capable of undergoing fission. Fission is a process whereby the nuclei of large unstable elements such as plutonium or uranium split into two smaller daughter nuclei, converting some of their mass to energy, which results in a large amount of heat. Fission naturally occ…urs in all samples of material capable of undergoing it, but it is the rate which allows heat to be released in a controlled manner, as in a nuclear reactor, or in the runaway explosion of a nuclear bomb. The unstable nuclei which undergo fission are not normally present in high numbers in the radioactive material, due to their quick decay into daughter nuclei. Instead, they are created by the collision of a free neutron with a more stable nucleus, such as U-235. The now slightly larger nucleus (in this example U-236), rapidly undergoes fission, forming daughter products, giving off energy and releasing 3 more neutrons. These neutrons can then go on to hit further U-235 atoms and cause further fission, in a process known as a chain reaction. Although theoretically this means that the reaction will proceed at a faster and faster rate as more and more neutrons are released, in most cases the concentrations of U-235 atoms are low enough that most neutrons do not go on to collide with them and allow the reaction to proliferate. However, if U-235 is present in sufficient concentrations, and at a sufficient (critical) mass, then enough neutrons will be absorbed that once started the reaction will rapidly proceed to completion, releasing vast amounts of energy. This explains the importance of enriching Uranium (increasing the ratio of U-235 to U-238, which does not undergo fission). If Uranium is slightly enriched, then it can provide a suitable fuel for nuclear power stations, able to continue a fission reaction without letting it run out of control. However, if it is highly enriched (around 80% U-235), then the initiation of a fission reaction will result in a rapid runaway chain reaction releasing huge amounts of energy - the explosion. This presents a problem, as the material must be enriched in advance of preparing the device. The material must therefore be arranged in the device in such a way that it does not allow a reaction to begin until some change is brought about to make it achieve a critical mass on detonation. For example, the Hiroshima bomb was made of 2 sections of fissile material, neither of which had a critical mass by itself. On detonation, a conventional explosive fired one section into the other section, causing the now larger sample of material to obtain a critical mass and undergo a chain reaction. ( Full Answer )
Preliminary studies started in the US in 1942. The ManhattanProject started in 1943 and started making its first bombs in June1945. The USSR started their project about the same time the US did, butbecause of the war was not able to get resources to build theindustrial infrastructure needed until a…fter the end of WW2. Theybegan building their first bombs in 1949. Basically, once the decision is made to build atomic bombs it takesa typical industrialized country 3 to 4 years to build theindustrial infrastructure needed to process and make the materialsand parts before they can actually start making atomic bombs.

Truman knew nothing of the Manhattan Project or the bomb until after he was sworn in as president. It was extremely secret. He did know, however, that the US military was already planning for the invasions of the first of the Home Islands of Japan, with one landing projected for November 1945, an…d another for March, 1946. Estimates were that there might be as many as one million American casualties in the first of these. And, it was assumed that all the Japanese would die. The military would either fight until exterminated, or commit suicide, and the civilians would try to fight or commit suicide as well. There had been mass suicides of Japanese civilians on Saipan and Okinawa, people throwing their children off cliffs and leaping after, rather than be overrun by the Americans. So, when Truman was told of the bomb program and its potential, he had to think about it. Finally, he realized that when it became known that the US had developed and possessed a weapon which might have won the war, but that he had ordered it not to be used, instead sending hundreds of thousands of Americans to their deaths, to say nothing of the millions of Japanese, that the American people would have his head. After weighing it out, he came to the conclusion that the bombs had to be tried, if it was possible this might shock the Japanese into surrendering their hopeless war, rather than have the war degenerate into a complete bloodbath. As he said to an aide upon making the decision, using the bomb " was right", under the conditions then existing. Everybody wishes it had not been necessary, and today there is a tendency to blame Truman or try to read evil into the decision. This perception flows from ignorance of the type of war Japan had carried on for four years, their stubborn refusal to give in, and their inevitable fight to the very last man for every flyspeck island. The next islands were the Japanese homeland, and the Japanese were expected to fight ten times harder for those. They had just demonstrated on Iwo Jima and Okinawa that the closer the US approached to their homeland, the more fanatical their defense. ( Full Answer )
President Harry Truman. Japan refused to surrender and the battles of Iwo Jima and Okiniwa had been blood baths with massive casualties on both sides. Atom bombs were dropped on Hirshoshima and Nagiskaki, and Japan surrendered soon after
If you meant "how to make an atomic bomb" it's a very complicated process. Fission atomic bombs require #235 Uranium or #240 plutonium and I am not at the liberty to say how much. In the design of little boy (atmoic bomb dropped on Japan) a hallow hydroge "bullet would fly into a plutonium "cup" and… cause an explosion which would split the nucleaus of the atom. This is as simple as I can get. I would check other online resources (or if somebody is willing to take a long enough Time to answer the question). It is nearly impossible to obtain all the materials needed to create a nuclear weapon, espescially with today with the worlds uranium deposits being closely watched. It's simple to say how a nuclear weapon works but how to make one can not be answered simply. This question is near impossible to answer here, but you can find online resources which can tell you the construction process of a nuclear weapon. Much of the information will be censored on most sites for good reason. ( Full Answer )

I won't give details here, but Richard Rhodes' book The Making of the Atomic Bomb is a good starting point. One detail that is well known is the MK-III Fat Man's Plutonium core was a solid sphere of Plutonium metal a bit over 3 inches in diameter. The explosive lenses crushed this down to a sphe…re about 1 inch in diameter in about 1 millisecond, before the neutron source initiated the reaction. The reaction lasted about 1 microsecond, after which the entire bomb was vapor. Just try to imaging squashing solid metal that much that fast, without it just squirting out in jets, and you have some idea of the difficulties faced by the early bomb designers. ( Full Answer )

Many, many countries helped in the Manhattan Project. . Robert J. Oppenheimer is usually credited with being the primary scientific leader of the U.S. Manhattan Project. However, the project was an immense undertaking, and there were literally thousands of very smart scientists involved, and it wo…uld be a mistake to credit the technological advancements required to build the bomb to even a small group of them. Oppenheimer is usually noted because he headed the scientific portion of the Manhattan Project - he was the lead science administrator, and while he did make some interesting contributions, his primary job was administrative, rather than research. Leo Szilard and Albert Einstein brought concerns to the FDR Administration in August 1939 about the serious possibility of an atomic bomb being feasible, and the concern inside the scientific community that Germany might have the technological and scientific know-how to create such a weapon for use in the just-started WW2. Einstein, however, did not do any of the initial research in atomic fission, nor did he play any role in the Manhattan Project. ( Full Answer )
Well, (I'll try to stay neutral with this) the US was staying out of World War 2, mostly, but Japan attacked Pearl Harbor before declaring war with the US, causing the US to join the war and fight them. The war was mostly over, Germany had surrendered, but Japan hadn't. For some reason or another,… I think it was because they didn't want to lose a bunch of troops trying to fly out and take Japan, the US dropped the atomic bomb. They then asked for Japan to surrender, and they told them they had another bomb, but Japan didn't, maybe they thought the US was bluffing or something, but the US dropped the second bomb and eventually Japan surrendered. Sorry it's kinda long, but that's the best way I can explain it. ( Full Answer )

Harry Truman was the president who had to make the decision. It was not an easy one to make. Truman had been a Senator from Missouri before basically being drafted to run with Franklin Roosevelt in 1944, as Roosevelt sought his fourth term in office. Roosevelt had decided to replace Henry Wallace as… vice president, and Truman was picked, much to his surprise. Truman tried to resist, but they got him by appealing to his patriotism. Once elected, Truman had exactly two meetings with FDR, altogether less than two hours, before FDR died on April 12, less than three months into his fourth term, and Truman became president. The atomic bomb program was very, VERY highly secret, and Truman knew nothing of it until after he was sworn in as president. The main factor that influenced Truman was that the US, poised to invade the Home Islands of Japan, was projecting one million American casualties, in the first two operations in the Home Islands. And, it was assumed that ALL the Japanese would have to be killed - civilians included. Up to that time, as the US "island hopped" across the Pacific, on each island battlefield the Japanese had to be killed to the last man, except for those who committed suicide. Very few prisoners had been taken. On both Saipan and Okinawa there had been large populations of Japanese civilians, and these had committed suicide rather than fall under American rule. Throwing their own children off of cliffs and leaping after, forming the children into a circle and pulling a pin on a hand grenade and giving it to them to toss around until it went off. Sailors on ships off Okinawa had to be issued rifles to shoot the bodies bobbing around their ships, in the hope of sinking them, before they could snag in the ships' propellers. In the Home Islands the Japanese were training women with bamboo spears, to take one American with them when the invasion came. Truman was at Potsdam, Germany, in mid July, when he learned that the atomic bomb had been successfully tested, and that the US thus had a viable weapon. He issued the "Potsdam Declaration" calling on Japan to surrender immediately, or face a "rain of destruction" the likes of which the world had never seen. There was no response. Truman was the only WWI combat veteran to become president, and the first war veteran as president since Theodore Roosevelt. He knew what war was, and understood the bloodbath that impended invading Japan. As he said to an adviser, if they didn't use the bomb, when it later was revealed that the US had spent billions developing a weapon which might have won the war, and Truman didn't use it, preferring instead to send millions of Americans into Japan to shed their blood or die, then Harry Truman could expect to be lynched by the families of those Americans. It has become fashionable in recent decades for revisionist "historians" to suggest that the US was just showing off for the Russians, knowing the Cold War was about to start, but there was nothing said at the time that would support this. It's claimed that the Japanese were trying to surrender, but instead of getting on the radio and calling up the Americans, they were going through the Russians or the Swedes or the Swiss or somebody. If the Japanese were really wanting to surrender, nobody would have been more happy to hear that than the Americans, and they should have let somebody know about it. I have never met anyone who was in uniform in 1945 who was not absolutely delighted that Truman dropped the bombs (remember, just the one was not enough to convince the Japanese) and they could go home alive.
