The site chosen for the explosive tests was Bikini Atoll. During 1946, following the end of WWII, the USA gathered together a “mock” naval fleet in order to test the effects of atomic bombs on the large fleet. After the displacement of the local inhabitants, 67 nuclear tests were carried out from 1946 to 1958, including the explosion of the first H-bomb (1952). Bikini Atoll has conserved direct tangible evidence that is highly significant in conveying the power of the nuclear tests, i.e. the sunken ships sent to the bottom of the lagoon by the tests in 1946 and the gigantic Bravo crater. Equivalent to 7,000 times the force of the Hiroshima bomb, the tests had major consequences on the geology and natural environment of Bikini Atoll and on the health of those who were exposed to radiation. Through its history, the atoll symbolises the dawn of the nuclear age, despite its paradoxical image of peace and of earthly paradise. This is the first site from the Marshall Islands to be inscribed on the World Heritage List 01 August 2010.
Around the same time French fashion designer Louis Reard was looking for a name for his new, controversial, tiny swimsuit design and the “Bikini” was launched. Bikini Lagoon became the final resting place for some of the most significant warships in history. Bikini Atoll was opened for diving in 1996 allowing divers to experience some of the most historic and amazing wreck diving in the world.

The massive 16.1-inch.45 caliber guns mounted on HIJMS NAGATO could fire a remarkable distance of more than 30 km.
On August 30, 1945, following the Japanese surrender, Nagato, the last surviving Japanese battleship, was boarded and secured by American sailors from USS Horase A. Bass. In March 1946 she was taken to Bikini Atoll for operation Crossroads, a series of atomic bomb tests. She was in such poor repair that on the way she had to be towed to Enewetok Atoll for emergency repairs.
In the first test (ABLE, an airburst) on July 01, 1946 she was 1,640 yards from ground zero and was not severely damaged. In the second test (BAKER, an underwater explosion) on July 25, 1946 she was severely damaged, eventually capsized sank five days later.

Lexington-class aircraft carrier — She survived the Test Able blast, an air burst on 1 July 1946 at Bikini Atoll, with only minor damage, but was damaged beyond repair by the Test Baker blast on 25 July 1946, an underwater atom bomb blast which was detonated under LSM-60 500 metres (500 yards) from the carrier. Salvage efforts were prevented by radioactivity, and seven-and-one-half hours after the blast, with her funnel collapsed across her deck, Saratoga slipped, stern first, beneath the surface of Bikini Lagoon.
DIVING: It is sinking on the sand as it is. Torpedo bomber [Grumman TBF Avenger] is sinking with bomb on the sand near Saratoga. Penetration is also possible, but it divides into several times.
