Operation Hurricane, Nuclear test site in Montebello Islands, Australia
Operation Hurricane was a series of nuclear weapons tests conducted between 1952 and 1956 on the Montebello Islands, a group of coral islands about 130 kilometers off the Pilbara coast in Western Australia. The test site spread across several small islands where detonations occurred both underwater and on land.
Britain conducted its first atomic test on October 3, 1952, detonating a weapon with a yield of 25 kilotons inside a ship off Trimouille Island. This breakthrough was followed by several additional tests in the series that solidified Britain's status as a nuclear power.
The nuclear tests marked Britain's emergence as a military superpower and shaped how the nation viewed its role in global affairs during the Cold War. Local Aboriginal communities had inhabited the region for thousands of years before the testing program arrived.
The site remains highly restricted due to safety concerns, with only certain areas open to visitors following radiation assessments. Anyone wanting to visit should check current access rules beforehand, as conditions can change based on monitoring results.
The underwater detonation left an unusual saucer-shaped depression on the seabed roughly 300 meters across and 6 meters deep. This physical trace of the test remains a distinctive feature of the seafloor in the area.
