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 (39 ft) of water, 350 metres (1,150 ft) off Trimouille Island. The explosion occurred 2.7 metres (8 ft 10 in) below the water line, and left a saucer-shaped crater on the seabed 6 metres (20 ft) deep and 300 metres (980 ft) across.
