Nuclear Weapons Program Of The United States
The United States was the first country to manufacture nuclear weapons and is the only country to have used them in combat, with the Atomic bombings of Hiroshima and Nagasaki, bombings of Hiroshima and Nagasaki in World War II against Empire of Japan, Japan. Before and during the Cold War, it conducted 1,054 Nuclear weapons testing, nuclear tests, and tested many nuclear triad, long-range nuclear weapons delivery systems. Between 1940 and 1996, the U.S. federal government spent at least US$ in present-day terms on nuclear weapons, including platforms development (aircraft, rockets and facilities), command and control, maintenance, waste management and administrative costs. It is estimated that the United States produced more than 70,000 nuclear warheads since 1945, more than all other nuclear weapon states combined. Until November 1962, the vast majority of U.S. nuclear tests were above ground. After the 1963 Partial Nuclear Test Ban Treaty, all testing was relegated undergroun ...

Nuclear Weapons Delivery
Nuclear weapons delivery is the technology and systems used to place a nuclear weapon at the position of detonation, on or near its target. All nine nuclear states have developed some form of medium- to long-range delivery system for their nuclear weapons. Alongside improvement of weapons, their development and deployment played a key role in the nuclear arms race. Strategic nuclear weapons are intended primarily as part of a doctrine of deterrence by threatening large targets, such as cities or military installations. These are generally delivered by some combination of land-based intercontinental ballistic missiles, sea-based submarine-launched ballistic missiles, and air-based strategic bombers carrying gravity bombs or cruise missiles. The possession of all three is known as a nuclear triad. Tactical nuclear weapons are intended for battlefield usage and/or destroying specific military, communications, or infrastructure targets, and generally have lower yields ...

Trinity Detonation T&B
The Trinity (, from 'threefold') is the Christian doctrine concerning the nature of God in Christianity, God, which defines one God existing in three, , consubstantial prosopon, divine persons: God the Father (Christianity), God the Father, God the Son (Jesus in Christianity, Jesus Christ) and God the Holy Spirit, three distinct persons (''Hypostasis (philosophy and religion), hypostases'') sharing one essence/substance/nature (''homoousion''). As the Fourth Lateran Council declared, it is the Father who s, the Son who is , and the Holy Spirit who proceeds. In this context, one essence/nature defines God is, while the three persons define God is. This expresses at once their distinction and their indissoluble unity. Thus, the entire process of creation and grace in Christianity, grace is viewed as a single shared action of the three divine persons, in which each person manifests the attributes unique to them in the Trinity, thereby proving that everything comes "from the F ...

Stockpile Stewardship
Stockpile stewardship refers to the United States program of reliability testing, viability, and the maintenance of its nuclear weapons without the use of nuclear testing. Because no new nuclear weapons have been developed by the United States since 1992, even its youngest weapons are at least years old (as of ). Aging weapons can fail or act unpredictably in a number of ways: the high explosives that compress their fissile material can chemically degrade, their electronic components can suffer from decay, their radioactive plutonium/uranium cores are potentially unreliable, and the isotopes used by thermonuclear weapons may be chemically unstable as well. Since the United States has also not tested nuclear weapons since 1992, this leaves the task of its stockpile maintenance resting on the use of simulations (using non-nuclear explosives tests and supercomputers, among other methods) and applications of scientific knowledge about physics and chemistry to the specific problems of ...

Comprehensive Nuclear-Test-Ban Treaty
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a multilateral treaty to ban nuclear weapons test explosions and any other nuclear explosions, for both civilian and military purposes, in all environments. It was adopted by the United Nations General Assembly on 10 September 1996, but has not entered into force, as nine specific nations have not ratified the treaty. History Background The movement for international control of nuclear weapons began in 1945, with a call from Canada and the United Kingdom for a conference on the subject. In June 1946, Bernard Baruch, an emissary of President Harry S. Truman, proposed the Baruch Plan before the United Nations Atomic Energy Commission, which called for an international system of controls on the production of atomic energy. The plan, which would serve as the basis for U.S. nuclear policy into the 1950s, was rejected by the Soviet Union as a US ploy to cement its nuclear dominance.

Nuclear Fallout
Nuclear fallout is residual radioactive material that is created by the reactions producing a nuclear explosion. It is initially present in the mushroom cloud, radioactive cloud created by the explosion, and "falls out" of the cloud as it is moved by the atmosphere in the minutes, hours, and days after the explosion. The bulk of the radioactivity from nuclear fallout comes from fission products, which are created by the nuclear fission reactions of the nuclear device. Un-fissioned bomb fuel (such as plutonium and uranium), and radioactive isotopes created by neutron activation, make up a smaller amount of the radioactive content of fallout. The amount of fallout and its distribution is dependent on several factors, including the overall yield of the weapon, the fission yield of the weapon, the height of burst of the weapon, and meteorological conditions. Fallout can have serious human health consequences on both short- and long-term time scales, and can cause radioactive conta ...

Partial Nuclear Test Ban Treaty
The Partial Test Ban Treaty (PTBT), formally known as the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, prohibited all nuclear weapons testing, test detonations of nuclear weapons except for those conducted underground nuclear weapons testing, underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties. Negotiations initially focused on a comprehensive ban, but that was abandoned because of technical questions surrounding the detection of underground tests and Soviet concerns over the intrusiveness of proposed verification methods. The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ban was also se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Test
Nuclear weapons tests are experiments carried out to determine the performance of nuclear weapons and the effects of their explosion. Nuclear testing is a sensitive political issue. Governments have often performed tests to signal strength. Because of their destruction and fallout, testing has seen opposition by civilians as well as governments, with international bans having been agreed on. Thousands of tests have been performed, with most in the second half of the 20th century. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed Ivy Mike, was tested at the Enewetak Atoll in the Marshall Islands on November 1, 1952 (local date), also by the United States. The largest nuclear weapon ever tested was the Tsar Bomba of the Soviet Union at Novaya Zemlya on October 30, 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
