To mark the sixtieth anniversary of the first UK atomic test explosion – ‘Operation Hurricane’ at the Monte Bello islands off the north-west coast of Australia in October 1952 - Nuclear Information Service has prepared an interactive timeline showing the history of the United Kingdom’s nuclear weapons programme. The timeline shows the importance of key events in the British nuclear weapons programme – both political and technical – from World War Two, when the UK first commenced research into atomic weapons, looking forward to the forthcoming decision on whether to replace Trident which will be taken after the next election. It also shows how international events have influenced the UK's nuclear programme over six decades.
