    Testing and deployment of nuclear weapons. Nuclear weapons have been used twice in war, both times by the United States against Japan near the end of World War II.On August 6, 1945, the U.S. Army Air Forces detonated a uranium gun-type fission bomb nicknamed "Little Boy" over the Japanese city of Hiroshima; three days later, on August 9, the U.S. Army Air Forces detonated a plutonium implosion ...

    Nuclear weapons possess enormous destructive power from nuclear fission or combined fission and fusion reactions. Building on scientific breakthroughs made during the 1930s, the United States, the United Kingdom, Canada, and free France collaborated during World War II, in what was called the Manhattan Project, to build a fission weapon, also known as an atomic bomb.

    The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War. It is a low to intermediate-yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design. The B61 is of the variable yield design with a yield of 0.3 to 340 kilotons in its various mods. It is a Full Fuzing Option weapon meaning it is equipped with the full range of fuzing and delivery options including air and ground burst fuzi

    The B53 was the basis of the W-53 warhead carried by the Titan II Missile, which was decommissioned in 1987. Although not in active service for many years before 2010, fifty B53s were retained during that time as part of the "hedge" portion of the Enduring Stockpile until its complete dismantling in 2011. The last B53 was disassembled on 25 October 2011, a year ahead of schedule. With its retirement, the largest bomb currently in service in the U.S. nuclear arsenal is the B83, with a maximum yie
