![]() In fact, between mid-April 1945 (when President Harry Truman took office) and mid-July, Japanese forces inflicted Allied casualties totaling nearly half those suffered in three full years of war in the Pacific, proving that Japan had become even more deadly when faced with defeat. Japan, however, vowed to fight to the bitter end in the Pacific, despite clear indications (as early as 1944) that they had little chance of winning. No Surrender for the Japaneseīy the time of the Trinity test, the Allied powers had already defeated Germany in Europe. Early on the morning of July 16, 1945, the Manhattan Project held its first successful test of an atomic device-a plutonium bomb-at the Trinity test site at Alamogordo, New Mexico. Robert Oppenheimer worked to turn these materials into a workable atomic bomb. They sent them to Los Alamos, New Mexico, where a team led by J.

This is part of AP’s effort to address widely shared misinformation, including work with outside companies and organizations to add factual context to misleading content that is circulating online. “It’s very odd to imagine they aren’t real, despite quite literally lots of actual physical evidence that you yourself can access if you’re interested,” Wellerstein said of nuclear weaponry. These bombings killed at least 200,000 people, including those who died from illnesses caused by radiation exposure even decades later, although it is impossible to know the full impact. In addition to documentation showing the tests were real and how they were filmed, are the bombings of Hiroshima and Nagasaki - the first and only time nuclear weapons were used in war. ![]() A report from 1953, on Operation Upshot-Knothole, also conducted in Nevada, describes film that was ruined due to nuclear radiation and cameras that were destroyed from a blast wave. The 1955 report, for instance, notes that major dust obstruction was an issue, especially for interior shots. Cameras used for exterior shots were housed on 10-to-18-foot towers secured in the ground with concrete, the height of which helped minimize dust obstruction.Īttempts to capture nuclear weapons testing on film were not always successful, despite these efforts. Among other precautions, these cameras were placed inside steel boxes with 2.5-inch thick lead shields. ![]() “These are very well-qualified engineers whose whole deal is taking unusual pictures of things and inventing entire cameras for doing this.”įor example, one report from 1955 on Operation Teapot, carried out in Nevada, describes 48 cameras used at distances between 2,750 to 10,500 feet from ground zero. “The people who did this film and camera work on nuclear tests, this is what they did,” Alex Wellerstein, a historian of science and nuclear technology at the Stevens Institute of Technology, told The Associated Press. More than 30 years later, the 1996 Comprehensive Nuclear Test-Ban Treaty banned all nuclear explosions on Earth.Ĭameras used to film these above-ground tests were protected by specially designed set-ups meant to withstand the enormous impact of nuclear weapons, as detailed in declassified military reports written at the time of the testing. This includes the above-ground testing in the footage that occurred before it was banned by the 1963 Partial Test Ban Treaty.
