The use of the atomic bombs on Japan was necessary for the revenge of the Americans and
played an important role in the Allied victory. The impact of the bombs killed hundreds of
thousands of people and the residual effect of radiation is still killing people today. People still
wonder why the bombs were dropped. The history of the world would have been changed
forever had the bombs not been dropped on Japan.
The atomic bomb took six years to develop and cost about two billion dollars. The most
complicated process in its development was trying to produce enough uranium to sustain a chain
reaction. The first bomb was dropped on the Japanese city, Hiroshima on August 6, 1945. The
bomb dropped on Hiroshima weighted 4.5 tons and the bomb used on Nagasaki weighed 10
kilotons. The single weapon dropped on Hiroshima, nicknamed "Little Boy," produced an
explosion equivalent to twenty thousand tons of TNT, which is roughly seven times greater than
all of the bombs dropped by all the allies on all of Germany in 1942. Three days later a second
plutonium bomb named "Fat Boy," was dropped on the Japanese city of Nagasaki. The impact
of the bombs on the cities and people was massive. Black rain containing large amounts of nuclear
fallout fell as much as 30 kilometers from the original blast site. A mushroom cloud rose to
twenty thousand feet in the air, and sixty percent of the city was destroyed. The shock wave and
its reverse effect reached speeds close to those of the speed of sound. The wind generated by the
bombs destroyed most of the houses and buildings within a 1.5 mile radius. Within the four square
miles destroyed by the bomb in Hiroshima, 48,000 buildings out of a total of 76,000 were
completely demolished. A mile from the explosion center, where the wind velocity was 190 miles
per hour and the pressure was 1,180 pounds per square feet, all b...
