'HMS ''Plym'' (F271)', was a River-class anti-submarine frigate built for the Royal Navy at Smiths Dock, Middlesbrough, England.
She was launched on February 4 1943, and commissioned on May 16, 1943, and was named after the River Plym in Devon, England.
She was deliberately destroyed when the first British nuclear weapon, a 25 kiloton bomb, was detonated inside her hull a few seconds before 9:30am local time on 3 October 1952. ''Plym'' was vaporised by the blast, and had been anchored in 12 metres of water at a distance of 400 metres from the island of Trimouille in the Monte Bello Islands, Australia. Although data acquisition would have been simplified by detonating the bomb on a tower above the ground, the test was conducted on board a ship to simulate the effects of a nuclear weapon being smuggled into a British harbour (which was considered a real possibility at the time). The test was called Operation Hurricane.
