Getting ready to unleash hell: Never-before-seen photos reveal final preparations for US nuclear attacks on Hiroshima and Nagasaki

Previously unseen pictures reveal the preparations in the hours leading up to the US nuclear attacks on Hiroshima and Nagasaki. The atomic bombings of the two cities in Japan were conducted by the US during the final stages of World War Two in August 1945. A uranium gun-type atomic bomb, code-named 'Little Boy' (pictured left) was dropped on Hiroshima on August 6. This was followed by a plutonium implosion-type bomb, called 'Fat Man' on Nagasaki on August 9 (a man signs his name on the completed bomb, bottom right and it is loaded in to a pit, top right). To this day, the bombings remain history's only acts of nuclear warfare.
