Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. Concerns about whethe. The U.S. carried out its last weapons test on September 23, 1992, with the detonation in Nevada of an approximately 20-kiloton device codenamed Divider. (A kiloton is .
Less than a month later, the United States dropped the same type of bomb on Nagasaki, Japan, just three days after detonating a smaller nuclear warhead over Hiroshima. The success of the Trinity test meant that both types of bombs -- the uranium design, untested but thought to be reliable, and the plutonium design, which had just been tested successfully -- were now available for use in the . The research shows that the first atomic bomb explosion’s effects had been underestimated, and could help more “downwinders” press for federal compensation.

The explosion yielded 15 Mt of TNT, far exceeding the expected yield of 4 to 8 Mt of TNT (6 predicted), [6] and was about 1,000 times more powerful than each of the atomic bombs dropped on Hiroshima and Nagasaki during World War II. The device was the most powerful nuclear weapon ever detonated by the United States. On 16 July 1945, Trinity – the first nuclear explosion ever – was conducted by the US Army in the Jornada del Muerto desert, New Mexico.

Ending Nuclear Testing. The history of nuclear testing began early on the morning of 16 July 1945 at a desert test site in Alamogordo, New Mexico when the United States exploded its first atomic bomb. In the early 1940s, the U.S. government authorized a top‑secret program of nuclear bomb testing and development, codenamed “The Manhattan Project.”The Nevada National Security Sites (N2S2 [1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010, [2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.. Formerly known as the Nevada Proving Grounds of the United States Army, the site .

In 1946, the US began its nuclear testing on Bikini Atoll in the Marshall Islands – a terrifying thought for many Australians. Some 75 years on, the evidence shows their fears were well-founded.
