A plutonium implosion device was detonated in the lagoon in the Monte Bello Islands in Western Australia. With the success of Operation Hurricane, Britain became the third nuclear power after the United States and the Soviet Union. During the Second World War, Britain commenced a nuclear weapons project, known as Tube Alloys, but the 1943 Quebec Agreement merged it with the American Manhattan Project. Several key British scientists worked as part of the British contribution to the Manhattan Project, but after the war
Atomic demolition munition and all were removed from stockpile by 1966. A weapons effect test of the TADM was made in the 1962 Johnny Boy ("Johnnie Boy") shot of the Dominic II series (which is more accurately referred to as Operation Sunbeam), the yield of Johnny Boy/Johnnie Boy was about .5 kt. A preceding ADM test which resulted in a comparable yield, was test shot "Danny Boy" of Operation Nougat, also producing a yield of about 0.5 kiloton. The "Special Atomic Demolition Munition (SADM)" was a family of man-portable nuclear weapons fielded by the US military in the 1960s, but never used in
