Britain effectively tests its initial atomic bomb at the Monte Bello Islands, off the northwest coast of Australia.
During World War II, 50 British scientists and engineers done the productive U.S. atomic bomb system at Los Alamos, New Mexico. After the war, plenty of of the scientists have already been enlisted in to the secret effort to create an atomic bomb for Britain. Work on the British A-bomb officially were only available in 1947, and Los Alamos veteran William Penney served because the program head. In February 1952, British Prime Minister Winston Churchill publicly announced the plans to check a British nuclear weapon, and on October 3 a 25-kiloton device-similar to the U.S. atomic bomb dropped on Nagasaki, Japan-was successfully detonated in the hull of the frigate HMS Plym anchored off the Monte Bello Islands. The test produced Britain the world’s third atomic energy immediately after the United States and the Soviet Union.
