these were the only instances where
nuclear weapons were used as a wartime
measure welcome to watchmojo.com and
today we’ll be learning more about the
atomic bombings in Japan during World
War two in the early days of the Second
World War President Franklin Delano
Roosevelt and the United States
government were warned by noted
scientific minds Albert Einstein and Leo
Szilard
of the possibility that Nazi Germany
might attempt to develop nuclear weapons
after being urged to undertake their own
research the US UK and Canada approved
the Manhattan Project in late 1941 by
1943 development and research on nuclear
bombs by the Manhattan Project began in
earnest several concepts for these
atomic weapons were explored but finally
two were chosen the first was codenamed
little boy this bomb used uranium as its
weapon and was propelled using the gun
method the little boy was not tested
prior to being used as a weapon in World
War two next came the fat man bomb its
nuclear explosion was caused by
plutonium and as opposed to the little
boy the fat man’s detonation was caused
by an implosion this device was tested
prior to its use in warfare on July 16
1945 the gadget was successfully tested
in the New Mexico desert this explosion
resulted in a bright flash of light and
heat followed by a shock wave and a
mushroom cloud that rose 40,000 feet
this event is credited with ushering in
the Atomic Age the United States and the
Allies then had nuclear weapons at their
disposal and plan to use them in an
effort to end the war just a few months
prior to the bombs test on May 8th the
Germans unconditionally surrendered
because of this Japan became the next
likely target and several Japanese
cities were then proposed Hiroshima and
Nagasaki were finally chosen as the most
strategic bombing locations due to their
importance in the war effort on July 26
1945 representatives of the US UK and
Chinese Nationalist government’s issued
the Potsdam Declaration to the Japanese
this document ordered the Japanese to
immediately surrender or they would face
prompt and utter destruction the
Japanese government chose to ignore
these extreme demands and made it clear
to the Japanese public that the
government would not acquiesce and so on
August 6 1945 in an effort to quickly
resolve the war the little boy bomb was
dropped on Hiroshima Japan by the Enola
Gay bomber at 8:15 a.m. local time the
bomb exploded above the city and caused
the destruction of roughly 5 square
miles of land not only that but 70,000
people were injured and 70 to 80
thousand more were instantly killed
Japan remained steadfast in their
refusal to bow to pressure three days
after the Hiroshima bombing the country
was still attempting relief efforts when
the boxcar bomber dropped the fat man
bomb on Nagasaki at 11:01 a.m. on August
9th the bomb missed its intended target
but the explosion above Nagasaki killed
between 40 and 75,000 people instantly
while burns and radiation poisoning were
immediate health problems caused by the
bombs the effects of both explosions
were felt for years to come cancers and
other diseases plagued the population in
the decades following the attacks the
American government prepared for the
possibility of further nuclear attacks
on Japan however it was unnecessary on
August 14th or 15th local time Japan
finally surrendered when the surrendered
documents were finally signed on
September 2nd 1945 the war was
effectively over
