A monument commemorates the 50th anniversary of first British Atomic Bomb test.

Operation Hurricane was the test of the first British atomic device on 3 October 1952. A plutonium implosion device was detonated in the lagoon between the Montebello Islands, Western Australia.

To test the effects of a ship-smuggled bomb (a threat of great concern to the British at the time), Hurricane was exploded inside the hull of HMS Plym (a 1,370-ton River class frigate) which was anchored in 12 metres of water, 350 metres  off Trimouille Island. The explosion occurred 2.7 metres below the water line, and left a saucer-shaped crater on the seabed 6 metres deep and 300 metres across.
