what are the names of atomic bombs which destroyed Hiroshima and Nagasaki?

Answer 1

Fat Man and Little Boy.

Answer 2

Little boy on Hiroshima

Fat Man on Nagasaki

Answer 3

on a the fateful day of 6th august 1945, a nuclear bomb made of URANIUM -235 was fused and it exploded 2000 feet above HIROSHIMA. The crucial decision was taken by the President of America, Prime minister of UK.etc,etc...

The impact of bomb attack on HIROSHIMA is not fully charted out even by scientists..

Some victims were permanently sterilised of radiation. The explosion generated a heat which fused tiles with a melting point of 1300*C as far as 600 yards away. Pregnant women were aborted and could not conceive again. Others were reduced by wasting diseases.The corpuscles of blood diminished drastically.Hair suddenly fell for no reason after the incident. A minor burn took many months to heal. Fever accompanied by a dysentry (like diarrhoea) sent temperatures rocketing up as high as 106*F. Then nearly a month later, came bleeding from the gums for no reason.

Major impact of the bomb was due to radiation. Whatever be the compelling reason, a measure of guilt remains in the minds of the citizens of UK , USA and CHINA for having placed the lives of people under threat in 1945...

The First Atomic Weapons
Last changed 30 March 1999
In some sort of crude sense which no vulgarity, no humor, no
overstatement can quite extinguish, the physicists have known sin;
and this is a knowledge which they cannot lose.

J. Robert Oppenheimer
Concurrent with the preparations for the Trinity test, preparations were being made for the delivery of operational atomic weapons to Tinian Island in the Pacific for use against Japan at the earliest possible date.

Two weapon designs were available for use - the gun assembly Little Boy bomb that used uranium highly enriched in U-235, and the implosion assembly Fat Man that used plutonium.

Little Boy and Fat Man On Display
At the National Atomic Energy Museum, Albuquerque, New Mexico, USA, representative weapon casings for the Little Boy and Fat Man type weapons are on display.

The Combat Weapons
After the detonation of the first plutonium bomb core in the Trinity test, the next weapon that was available was the completed Little Boy. It was this weapon that was dropped on Hiroshima. Another Little Boy weapon would not have been ready for months, for this reason only one Little Boy unit was prepared. In contrast many Fat Man bomb assemblies were on hand (without plutonium), and the actual "Fat Man bomb" delivered against Japan only existed when assembly of the Fat Man unit with the plutonium core was completed shortly before the mission.

The second plutonium bomb core was delivered to Tinian for use in the first deliverable Fat Man weapon against Kokura arsenal only days after the arrival of Little Boy. Due to weather problems related problems, the Kokura primary target was scrubbed and the secondary target Nagasaki was bombed.
