The United States nuclear program since its inception has experienced accidents of varying forms, ranging from single-casualty research experiments (such as that of Louis Slotin during the Manhattan Project), to the nuclear fallout dispersion of the Castle Bravo shot in 1954, to accidents such as crashes of aircraft carrying nuclear weapons ...
There are other types of nuclear weapons as well. For example, a boosted fission weapon is a fission bomb that increases its explosive yield through a small number of fusion reactions, but it is not a fusion bomb. In the boosted bomb, the neutrons produced by the fusion reactions serve primarily to increase the efficiency of the fission bomb.
The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons.As the country that invented nuclear weapons, the U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II.

Israel likely has nuclear weapons. Iran is close. In the Cold War, when the U.S. and former Soviet Union were the two nuclear superpowers, a concept of deterrence could be established. The threat ...
The first, a limited nuclear war [22] (sometimes attack or exchange), refers to the controlled use of nuclear weapons, whereby the implicit threat exists that a nation can still escalate their use of nuclear weapons. For example, using a small number of nuclear weapons against strictly military targets could be escalated through increasing the ...
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
Having two nuclear peer adversaries heightens the need for America to update its nuclear warheads and weapon systems.
