Nuclear weapons and the United Kingdom the year. During Operation Hurricane, an atomic bomb was detonated on board the frigate anchored in a lagoon in the Monte Bello Islands in Western Australia on 3 October 1952. Britain thereby became the third country to develop and test nuclear weapons. This led to the development of the first deployed weapon, the Blue Danube free-fall bomb. It had a diameter, 32 explosive lens implosion system with a levitated pit suspended within a natural uranium tamper. The warhead was contained within a bomb casing measuring diameter and long, and it weighed approximately , of which about was high explosive. The
Operation Tumbler–Snapper Operation Tumbler–Snapper Operation Tumbler–Snapper was a series of atomic tests conducted by the United States in early 1952 at the Nevada Test Site. The "Tumbler-Snapper" series of tests followed "Operation Buster-Jangle", and preceded "Operation Ivy". The "Tumbler" phase, sponsored by the Atomic Energy Commission consisted of three airdrops which were intended to help explain discrepancies in the actual and estimated blast shock wave damage noted on previous detonations, and to establish more accurately the optimum height of burst. The "Snapper" phase, sponsored by the Department of Defense consisted of one airdrop and four tower shots intended to test various new
