Trinity Test atom bomb seconds after detonation, 1945. This image is part of a sequence of views looking north, showing the stages of development of the typical 'mushroom cloud'. The Trinity Test atom bomb, known as 'The Gadget', was detonated with a yield equivalent to 22 kilotons of TNT. This was the first detonation of a nuclear weapon, carried out by the US Army on 16 July 1945 in New Mexico, USA. It was developed as part of the Manhattan Project at the Los Alamos Laboratory. The core consisted of a cylinder of uranium with plutonium and beryllium inside. For the full sequence of images, see C045/6782 to C045/6786.
