[Nuclear Weapon Test]
This youtube video shows nuclear weapon tests from 1945 to 1998 including the bombings of Hiroshima and Nagasaki . The number of critical nuclear weapon tests until now is 2056. Major tests as we know well are stated below: (1)Nevada National Security Site, (2)Manhattan Project, (3)Atomic bombings of Hiroshima and Nagasaki. |
(1) Nevada National Security Site (N2S2)
Previously, It was called Nevada Test Site (NTS). This site was established on 11 January 1951 for the testing of nuclear devices, covering approximately 1,360 square miles of desert and mountainous terrain. Nuclear testing at the Nevada Test Site began with a 1-kilotonne-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on 27 January 1951. Many of the iconic images of the nuclear era come from the NTS.
The NTS was the United States's primary location for tests in the 500-to-1,000-kilotonne-of-TNT (2,100-to-4,200 TJ) range. 126 tests were conducted elsewhere, including most larger tests. Many of these occurred at the Pacific Proving Grounds in the Marshall Islands. During the 1950s, the mushroom clouds from atmospheric tests could be seen for almost 100 mi (160 km). The city of Las Vegas experienced noticeable seismic effects, and the distant mushroom clouds, which could be seen from the downtown hotels, became tourist attractions. The last atmospheric test detonation at the Nevada Test Site was "Little Feller I" of Operation Sunbeam, on 17 July 1962.

(2) Manhattan Project
The Manhattan Project was a secret military project created in 1942 to produce the first US nuclear weapon. Fears that Nazi Germany would build and use a nuclear weapon during World War II triggered the start of the Manhattan Project, which was originally based in Manhattan, New York. The Manhattan Project was led by the United States with the support of the United Kingdom and Canada. until 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. During the war, two types of atomic bomb were developed. A relatively simple gun-type fission weapon was made usinguranium-235, an isotope that makes up only 0.7 percent of natural uranium.
Clearly, the world has been dramatically changed by the events associated with the Manhattan Project. Ever since those fateful days, the threat of atomic or nuclear war has hung over the heads of the world’s population, pervading into countless aspects of our lives.

(3) Atomic bombings of Hiroshima and Nagasaki
A one- megaton bomb would have produced the explosive power of 80 ‘Little Boy’ bombs. Therefore 12 thousand megatons would have been the equivalent of 960,000 ‘Little Boy’ bombs and 20 thousand megatons would have been 1,600,000. Some scientists believed that just a fraction of these bombs would have thrown up enough dust and detritus after an explosion that would have blocked out the light of the sun. The estimated figure was that at 10 miles above the Earth's surface, 74% of the Sun's light would be blocked.
The decision to drop the atomic bombs on the cities of Hiroshima and Nagasaki is one of the most controversial issues of the 20th century. Many modern historians have criticized the commonly held perceptions that the bomb shortened the war, saved American lives and prevented USSR’s sharing in the post-war administration of Japan. In 1995, on the 50th anniversary of the bombing, an exhibit designed to commemorate the event resulted in unprecedented controversy for the Smithsonian Institution . The American Legion and other veteran’s organizations successfully lobbied against the inclusion of quotes from a number of notables including Dwight D. Eisenhower that questioned the necessity of the bomb’s use.
