It took about 5 years to make a proper nuclear weapon.
The United States for the first time ever used the Atomic bomb on the Japanese cities of Hiroshima and Nagasaki. The effects of radiation on the population was to continue for many years.
It took only one atomic bomb.

During the final stages of World War II in 1945, the United States conducted two atomic bombings against Japan in the cities of Hiroshima and Nagasaki.During the final stages of World War II in 1945, the United States conducted two atomic bombings against Japan in the cities of Hiroshima and Nagasaki. The bombs were made in the US by Plutoniom and Uranium from the mines of Congo, Africa. "Little Boy" was the codename of the atomic bomb dropped on Hiroshima on August 6, 1945 by the Boeing B-29 Superfortress Enola Gay, piloted by Colonel Paul Tibbets of the 393d Bombardment Squadron, Heavy, of the United States Army Air Forces."Fat Man" is the codename for the atomic bomb that was detonated over Nagasaki, Japan, by the United States on August 9, 1945 and was dropped from a B-29 bomber Bockscar, piloted by Major Charles Sweeney of the 393d Bombardment Squadron, Heavy. Through self-sustaining nuclear fission (chain reaction), an atomic bomb emits a huge amount of energy instantaneously. The atomic bomb dropped on Hiroshima was a gun-barrel bomb. The uranium was divided into two pieces, both less than a critical mass and placed at either end of a cylinder. When one piece was fired into the other, critical mass was achieved. Though the bomb was long and thin in shape, it grew shorter over the course of the project. Hence, the final bomb was called "Little Boy." A detonator was used to trigger the explosion. One mass of uranium was fired into the other. The neutrons created by that firing started a fission chain reaction, generating a tremendous amount of energy instantaneously.
it was either kill a few thousand with an atomic bomb, or invade japan and lose millions of japanese and americans. Saves lives in the long run.

The military knew about the weapon but at the time the President has not decided on the course he would choose. On 16 Jul 1945, while President of the United States Harry Truman was at Potsdam, Germany to meet with his Allied counterparts, long-waited results reached him: The Manhattan Project, the American effort at building the atomic bomb, successfully detonated the first bomb during a test at Los Alamos, New Mexico, United States. Truman, unwilling to risk the huge amount of lives that might be lost on both sides should the Allies invade the Japanese home islands, ordered the usage of the new technology. The scientists presented them with two such weapons, while the military sought uranium to produce a third.
