What about Hiroshima and Nagasaki bombing?
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.
What is one city destroyed by an atomic bomb in 1945?
One city destroyed by an atomic bomb in 1945 is Hiroshima, Japan. On August 6, the United States dropped the bomb known as "Little Boy," resulting in massive destruction and loss of life. The bombing led to an estimated 140,000 deaths by the end of the year, with long-term effects from radiation exposure. This event played a significant role in the conclusion of World War II.
Where did the us use two atomic bombs?
The United States used two atomic bombs during World War II on the Japanese cities of Hiroshima and Nagasaki. The first bomb, codenamed "Little Boy," was dropped on Hiroshima on August 6, 1945, followed by the second bomb, "Fat Man," on Nagasaki three days later, on August 9, 1945. These bombings contributed to Japan's surrender and the end of the war, but they also resulted in significant civilian casualties and long-term effects from radiation.

What time of the day was the hiroshima's bomb dropped?
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.
