Atomic bombings of Hiroshima and Nagasaki

The United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, with the consent of the United Kingdom, as required by the Quebec Agreement.

During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack (at 11:02 a.m., August 9, 1945 'Japan Standard Time (UTC+9)').

By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands.

It conducted the atomic bombings of Hiroshima and Nagasaki, Japan, in August 1945.

Towards the end of World War II, Hiroshima is best remembered as the first city targeted by a nuclear weapon, when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city at 8:15 a.m. on August 6, 1945.

This undertaking was preceded by a conventional and firebombing campaign which devastated 67 Japanese cities.

During early August 1945, the cities of Hiroshima and Nagasaki were struck and mostly destroyed by atomic bombs.

The war in Europe had concluded when Germany signed its instrument of surrender on May 8, 1945, and the Allies turned their full attention to the Pacific theater. In 1945, the Pacific War between the Empire of Japan and the Allies entered its fourth year.

The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the Allies, accompanied by the Soviet Union's declaration of war and invasion of Manchuria and other territories on 9 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945.

Another B-29 dropped a plutonium implosion bomb ("Fat Man") on Nagasaki three days later.

"Fat Man" was the codename for the nuclear bomb that was detonated over the Japanese city of Nagasaki by the United States on 9 August 1945.

Since the atomic bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated over two thousand times for testing and demonstration.

By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands.

B-29s also dropped the atomic bombs on Hiroshima and Nagasaki which contributed to the end of World War II.

In the final year of World War II, the Allies prepared for a very costly invasion of the Japanese mainland.

Following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6and 9 August respectively.

Scholars have extensively studied the effects of the bombings on the social and political character of subsequent world history and popular culture, and there is still much debate concerning the ethical and legal justification for the bombings.

The debate over the atomic bombings of Hiroshima and Nagasaki concerns the ethical, legal, and military controversies surrounding the atomic bombings of Hiroshima and Nagasaki on 6 August and 9 August 1945 at the close of World War II (1939–45).

Scholars have extensively studied the effects of the bombings on the social and political character of subsequent world history and popular culture, and there is still much debate concerning the ethical and legal justification for the bombings.

This is a list of cultural products made about the atomic bombings of Hiroshima and Nagasaki.

In 1945, the Pacific War between the Empire of Japan and the Allies entered its fourth year.

However, after many Allied victories and following the Soviet Union's declaration of war against Japan on August 9, 1945, and subsequent invasion of Manchuria and other territories, and the atomic bombings of Hiroshima and Nagasaki, the Empire surrendered to the Allies on August 15, 1945.

On August 6, one of the modified B-29s dropped a uranium gun-type bomb ("Little Boy") on Hiroshima. Little Boy was a gun-type fission weapon that used uranium-235, a rare isotope of uranium separated at the Clinton Engineer Works at Oak Ridge, Tennessee.

The Hiroshima bombing was the second man-made nuclear explosion in history, after the Trinity test.

Japan surrendered to the Allies on August 15, six days after the Soviet Union's declaration of war and the bombing of Nagasaki.

On August 6, 1945, at 8:15 AM local time, the United States detonated an atomic bomb over the Japanese city of Hiroshima.

In the Pacific, the Allies returned to the Philippines, recaptured Burma, and invaded Borneo.

United States and Philippine Commonwealth military forces were progressing in liberating territory and islands when the Japanese forces in the Philippines were ordered to surrender by Tokyo on August 15, 1945, after the dropping of the atomic bombs on mainland Japan and the Soviet invasion of Manchuria.

By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands.

This batch included the aircraft which were used in the atomic bombings of Hiroshima and Nagasaki in August 1945.

Japan surrendered to the Allies on August 15, six days after the Soviet Union's declaration of war and the bombing of Nagasaki.

The commencement of the invasion fell between the US atomic bombings of Hiroshima on August 6 and Nagasaki on August 9.

In the final year of World War II, the Allies prepared for a very costly invasion of the Japanese mainland.

The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war and the invasion of Manchuria.

The Japanese government signed the instrument of surrender on September 2 in Tokyo Bay, which effectively ended World War II.

(Atomic bombing of Hiroshima)

Like most strategic bombing during World War II, the aim of the air offensive against Japan was to destroy the enemy's war industries, kill or disable civilian employees of these industries, and undermine civilian morale.

The US air raids on Japan began in earnest in October 1944 and by March 1945 had started their escalation into widespread firebombing, which culminated in the atomic bombings of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively.

Operation Olympic was to be followed in March 1946 by Operation Coronet, the capture of the Kantō Plain, near Tokyo on the main Japanese island of Honshū by the U.S. First, Eighth and Tenth Armies, as well as a Commonwealth Corps made up of Australian, British and Canadian divisions.

However, the atomic bombings of Hiroshima and Nagasaki cancelled the invasion, and the Eighth Army found itself in charge of occupying it peacefully.

Groves appointed J. Robert Oppenheimer to organize and head the project's Los Alamos Laboratory in New Mexico, where bomb design work was carried out.

In August 1945, the weapons were used in the atomic bombings of Hiroshima and Nagasaki.

Little Boy was a gun-type fission weapon that used uranium-235, a rare isotope of uranium separated at the Clinton Engineer Works at Oak Ridge, Tennessee.

The Clinton Engineer Works (CEW) was the production installation of the Manhattan Project that during World War II produced the enriched uranium used in the 1945 bombing of Hiroshima, as well as the first examples of reactor-produced plutonium.

Secretary of War Henry L. Stimson was sufficiently concerned about high American estimates of probable casualties to commission his own study by Quincy Wright and William Shockley.

He supported the atomic bombings of Hiroshima and Nagasaki.

There was a Japanese nuclear weapon program, but it lacked the human, mineral and financial resources of the Manhattan Project, and never made much progress towards developing an atomic bomb.

Like the German nuclear weapons program, it suffered from an array of problems, and was ultimately unable to progress beyond the laboratory stage before the atomic bombings of Hiroshima and Nagasaki and the Japanese surrender in August 1945.
