75 Years Ago — US Detonates First Nuclear Weapon (July 16 1945)

“We knew the world would not be the same. A few people laughed, a few people cried. Most people were silent. I remembered the line from the Hindu scripture, the Bhagavad Gita. Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, ‘Now I am become Death, the destroyer of worlds.’ I suppose we all thought that, one way or another.”

Robert Oppenheimer

July 16 2020 — On July 16 1945, the US detonated the world’s first nuclear weapon, a plutonium-based device, near Alamogordo, New Mexico. Trinity, as the test was known, was successful. Three weeks later, a second successful detonation took place — over the Japanese city of Hiroshima. Follow us on Twitter: @INTEL_TODAY

Trinity was the code name of the first detonation of a nuclear weapon. It was conducted by the United States Army at 5:29 a.m. on July 16, 1945, as part of the Manhattan Project.

The test was conducted in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range.

The test was of an implosion-design plutonium device, informally nicknamed “The Gadget”, of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945.

The Gadget’s detonation released the explosive energy of about 22 kilotons of TNT (92 TJ).
