Atomic bomb dropped on Nagasaki

On August 9, 1945, a second atom bomb is dropped on Japan by the United States, at Nagasaki, resulting finally in Japan’s unconditional surrender.

The devastation wrought at Hiroshima was not sufficient to convince the Japanese War Council to accept the Potsdam Conference’s demand for unconditional surrender. The United States had already planned to drop their second atom bomb, nicknamed “Fat Man,” on August 11 in the event of such recalcitrance, but bad weather expected for that day pushed the date up to August 9th. So at 1:56 a.m., a specially adapted B-29 bomber, called “Bockscar,” after its usual commander, Frederick Bock, took off from Tinian Island under the command of Maj. Charles W. Sweeney.

An atomic bomb, codenamed "Little Boy," was dropped over Hiroshima Japan on August 6, 1945. The bomb, which detonated with an energy of around 15 kilotons of TNT, was the first nuclear weapon deployed in wartime.

Nagasaki was a shipbuilding center, the very industry intended for destruction. The bomb was dropped at 11:02 a.m., 1,650 feet above the city. The explosion unleashed the equivalent force of 22,000 tons of TNT. The hills that surrounded the city did a better job of containing the destructive force, but the number killed is estimated at anywhere between 60,000 and 80,000 (exact figures are impossible, the blast having obliterated bodies and disintegrated records).

General Leslie R. Groves, the man responsible for organizing the Manhattan Project, which solved the problem of producing and delivering the nuclear explosion, estimated that another atom bomb would be ready to use against Japan by August 17 or 18—but it was not necessary. Even though the War Council still remained divided (“It is far too early to say that the war is lost,” opined the Minister of War), Emperor Hirohito, by request of two War Council members eager to end the war, met with the Council and declared that “continuing the war can only result in the annihilation of the Japanese people…” The Emperor of Japan gave his permission for unconditional surrender.
