|Before A-bombings - Why were the A-bombs dropped?
In 1939, a full-scale war broke out in Europe and in 1941, a war began between Japan and the United States. In August 1942 the United States, fearing that Germany might be developing
a new type of bomb using atomic energy (the vast energy produced during nuclear
fission), launched the Manhattan Project to develop an atomic bomb (A-bomb).
Three years later, the atomic bomb was created.
|Japan selected as A-bomb target
In an attempt to end the war, the United States was
developing atomic bombs originally planned for use against Germany. However,
before the bombs’ full development Germany had surrendered, in May 1945. The
plan was therefore changed, to use the new weapons on Japan. The United States
held discussions to select the A-bombing target cities in Japan, and finally
decided to drop A-bombs on Hiroshima, Kokura and Nagasaki.
After successfully carrying out an A-bomb test in July
1945, the United States dropped the first atomic bomb on Hiroshima, on August
6 of the same year.
The second atomic bomb was initially scheduled to be dropped
on Kokura on August 9, three days after the first bombing. However, when the
U.S. B-29 bomber carrying the A-bomb arrived over Kokura, the city was blanketed
with smoke. Unable to drop the device on the primary target, the B-29 made its
way to its secondary target, Nagasaki and dropped its deadly
cargo over Nagasaki from a height of 9,600 meters. At 11:02 a.m.,the
A-bomb exploded approximately 500 meters above Matsuyama-machi.
