Churchill Unveils Britain's Bomb: Cold War Escalates

Britain tested its first nuclear device, codenamed Hurricane, on October 3, 1952, detonating a plutonium implosion bomb inside the hull of the frigate HMS Plym anchored off the Montebello Islands in Western Australia. Prime Minister Winston Churchill had authorized the program in 1947, driven by the conviction that Britain could not remain a first-rate power dependent on American nuclear protection. The test made Britain the third nation to join the nuclear club, after the US and Soviet Union. Churchill chose to announce the weapon publicly on February 26, 1952, months before the actual test, as a statement of intent. The bomb vaporized the ship and left a crater on the seabed 20 feet deep and 300 feet across. Britain subsequently tested larger weapons at Maralinga in South Australia, contaminating Aboriginal lands with radioactive fallout that was not properly cleaned up for decades. The program gave Britain an independent deterrent but tied its nuclear forces to American delivery systems.
