At once fascinating and horrific, this book details the conception, development and impact of the atomic bombs infamously dropped over Hiroshima and Nagasaki in August 1945. The obliteration of Hiroshima and Nagasaki in August 1945 brought the world to a stand still. This unimaginable shock confirmed to the world that the race to develop a working atomic weapon during World War II had been won by the American-led international effort. Horrific and controversial even today, these first uses of the atomic bomb had intense ramifications not only on the continued development of the bomb, but also on politics and popular culture. As well as the technological development, historian James Delgado also examines how the US Army Air Force had to develop the capacity to deliver the weapons, and examines the sites where development and testing took place, in order to give a comprehensive history of the dawning of the nuclear age.
