{{ safesubst:#invoke:Unsubst||$N=Use mdy dates |date=__DATE__ |$B= }} {{#invoke:Infobox|infobox}} {{#invoke:Infobox|infobox}} Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army on July 16, 1945, as part of the Manhattan Project. The White Sands Proving Ground, where the test was conducted, is in the Jornada del Muerto desert about {{safesubst:#invoke:convert|convert}} southeast of Socorro, New Mexico, on the Alamogordo Bombing and Gunnery Range. The only structures originally in the vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. A base camp was constructed, and there were 425 people present on the weekend of the test.

The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne. 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 complexity of the design required a major effort from the Los Alamos Laboratory, and concerns about whether it would work led to a decision to conduct the first nuclear test.

Fears of a fizzle led to the construction of a steel containment vessel called Jumbo that could contain the plutonium, allowing it to be recovered, but Jumbo was not used. A rehearsal was held on May 7, 1945, in which {{safesubst:#invoke:convert|convert}} of high explosive spiked with radioactive isotopes were detonated. The Gadget's detonation released the explosive energy of about {{safesubst:#invoke:convert|convert}}. Observers included Vannevar Bush, James Chadwick, James Conant, Thomas Farrell, Enrico Fermi, Leslie Groves, Robert Oppenheimer, and Richard Tolman.

The test site is now part of the White Sands Missile Range. It was declared a National Historic Landmark district in 1965, and listed on the National Register of Historic Places the following year.
