HMS Plym (K271), 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. The ship 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 on October 3, 1952 whilst she was anchored in 12 metres of water around 400 metres from the island of Trimouille in the Monte Bello Islands, Australia. The test was called Operation Hurricane.
