60th Anniversary of Castle BRAVO Nuclear Test, the Worst Nuclear Test
in U.S. History
Blast Had Far Greater Explosive Yield than Expected, Equivalent to
Fallout from the Test Contaminated the Marshall Islands and Japanese
Fishermen on the Fortunate Dragon (Fukuryu Maru)
Consequences of BRAVO Created Outrage around the World and Pressure
to Ban Nuclear Weapons Tests
National Security Archive Electronic Briefing Book No. 459 February 28, 2014Washington, D.C., February 28, 2014 – Sixty years ago, on 1 March 1954 (28 February on this side of the International Dateline), on Bikini Atoll in the Marshall Islands, the U.S. government staged the largest nuclear test in American history. The BRAVO shot in the Castle thermonuclear test series had an explosive yield of 15 megatons, 1000 times that of the weapon that destroyed Hiroshima and nearly three times the 6 megatons that its planners expected. To recall this shocking event the National Security Archive posts today a selection of documents about the BRAVO shot and its consequences, mainly from State Department records at the National Archives.
Castle BRAVO spewed radioactive fallout around the world and gravely sickened nearby inhabitants of the Marshall Islands, then under a U.S. trusteeship, and 236 were evacuated as well as 28 American military personnel on a nearby island. Twenty-three Japanese fishermen were also contaminated, which made the test known to the world and roiled U.S-Japanese relations. While the U.S. government claimed at the time that a shift in the wind spread the fallout far from the test site, a recent U.S. government report demonstrates that it was the volcanic nature of the explosion that dumped the fallout nearby. The adverse health effects for inhabitants of Rangelop Atoll, 110 miles away from the test site, were severe and some islands remained uninhabitable for years. This radiological calamity had a significant impact on world opinion and helped spark the movement for a nuclear test moratorium which ultimately led to the 1963 Limited Test Ban Treaty.
