The first test explosion of a fission nuclear device was tested on July 16, 1945 at Alamogordo, New Mexico, as the culmination of the WWII Manhattan Project. The device and test, codenamed Trinity, had an estimated yield of approximately 20 kilotons, and was the first successful test of a plutonium implosion device.

There were many hi-speed cameras running to document the event, and they show the explosion at its initial detonation. The camera technology was pioneered by EG&G founder Harold Edgerton, and the still frame picture of the initial explosion of the Trinity test is one of the most iconic and famous photographs of the 20th century.

In the mid '90's following the breakup of the USSR, the Energy Department declassified many documents and test films, and they were eventually made into a documentary video named "Trinity and Beyond: The Atomic Bomb Movie". It is an excellent record of the Trinity test and all subsequent milestone nuclear and thermonuclear detonations. It is available on DVD and is an excellent resource for anyone interested in the field or subject.

What is an nuclear bomb?

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive.[1]Thus, even single small nuclear devices no larger than traditional bombs can devastate an entire city by blast, fire and radiation. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major focus of international relations policy since their debut.In the history of warfare, only two nuclear weapons have been detonated offensively, both near the end of World War II. The first was detonated on the morning of 6 August 1945, when the United States dropped a uranium gun-type device code-named "Little Boy" on the Japanese city of Hiroshima. The second was detonated three days later when the United States dropped a plutonium implosion-type device code-named "Fat Man" on the city of Nagasaki, Japan. These bombings resulted in the immediate deaths of around 120,000 people (mostly civilians) from injuries sustained from the explosion and acute radiation sickness, and even more deaths from long-term effects of ionizing radiation. The use of these weapons was and remains controversial.Since the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over two thousand occasions for testing purposes and demonstration purposes. A few states have possessed such weapons or are suspected of seeking them. The only countries known to have detonated nuclear weapons-and that acknowledge possessing such weapons-are (chronologically) the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea. Israel is also widely believed to possess nuclear weapons, though it does not acknowledge having them.[2]
