Britain soon became dependent on the United States for its nuclear weapons, as it lacked the resources to produce a range of designs. The treaty allowed the UK to receive US nuclear weapons for the Royal Air Force (RAF) and British Army of the Rhine (BAOR) under Project E. Similar custody arrangements were made for the Thor missiles supplied under Project Emily. The UK was able to carry out underground nuclear tests at the US Nevada Test Site, where the first British test took place on 1 March 1962. British nuclear testing in the United States continued until it was abruptly halted by President George H. W. Bush in October 1992. Major subcritical nuclear tests continued to occur, most notably the Etna test in February 2002 and the Krakatau test in February 2006.
