Trinity was thecode name given to thenuclear test that saw the first detonation of anuclear weapon. The code name was assigned byJ. Robert Oppenheimer, the director of theLos Alamos Laboratory, after a poem byJohn Donne. It was conducted on July 16, 1945, as part of theManhattan Project on theAlamogordo Bombing and Gunnery Range in theJornada del Muerto desert. The test used aFat Man bomb of the same design as thatdetonated over Nagasaki. The complex design of theimplosion-type nuclear weapon required a major effort from the Los Alamos Laboratory, and testing was required to allay fears that it would not work. Its detonation(video featured) produced the explosive power of about 20kilotons of TNT (84terajoules). The test site is now part of theWhite Sands Missile Range. It was declared aNational Historic Landmark District in 1965, and listed on theNational Register of Historic Places the following year.(This article is part of afeatured topic:History of the Manhattan Project.)
