Tactical Nuclear Weapons
A tactical nuclear weapon (TNW) or non-strategic nuclear weapon (NSNW) is a nuclear weapon that is designed to be used on a battlefield in military situations, mostly with friendly forces in proximity and perhaps even on contested friendly territory. Generally smaller in explosive power, they are defined in contrast to strategic nuclear weapons, which are designed mostly to be targeted at the enemy interior far away from the war front against military bases, cities, towns, arms industries, and other hardened or larger-area targets to damage the enemy's ability to wage war. No tactical nuclear weapon has ever been used in a combat situation. Tactical nuclear weapons include gravity bombs, short-range missiles, artillery shells, land mines, depth charges, and torpedoes which are equipped with nuclear warheads. Also in this category are nuclear armed ground-based or shipborne surface-to-air missiles (SAMs) and air-to-air missiles. Small, two-man portable or truck-portable tactical w ...

Cold War Weapons Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Nuclear Weapons 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 bombings of Hiroshima and Nagasaki in World War II. Before and during the Cold War, it conducted 1,054 nuclear tests, and tested many 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 acceptance of the Partial Nuclear Test Ban Treaty, all testing was relegated underground, in order to prevent the dispersion of nuclear fallout. By 1998, at least US$759 million had bee ...

Special Atomic Demolition Munition
The Special Atomic Demolition Munition (SADM), also known as the XM129 and XM159 Atomic Demolition Charges, and the B54 bomb was a nuclear man-portable atomic demolition munition (ADM) system fielded by the US military from the 1960s to 1980s but never used in combat. History and design At the time of the weapon's development, the existing Atomic Demolition Munition (ADM) was the T-4 Atomic Demolition Munition. Its transport required 4 men, each carrying a section of the weapon. Development began in June 1960 and an interim Mark 54 Mod 0 (now called the B54-0) weapon was put into production in April 1963. Production of the B54 Mod 1 SADM began in August 1964. The weapon was in diameter, long, and weighed . It included the warhead, a fuzing and firing system with a mechanical timer, a ferroelectric firing set and a sealed housing. The body was constructed with aluminum forgings and molded fiberglass, and foam-rubber insulation was used between the warhead and case. Dials w ...

MADM Emplacement
Atomic demolition munitions (ADMs), colloquially known as nuclear land mines, are small nuclear explosive devices. ADMs were developed for both military and civilian purposes. As weapons, they were designed to be exploded in the forward battle area, in order to block or channel enemy forces. Non-militarily, they were designed for demolition, mining or earthmoving. However, apart from testing, they have never been used for either purpose. Military uses Instead of being delivered to the target by missiles, rockets, or artillery shells, ADMs were intended to be emplaced by soldiers. Due to their relatively small size and light weight, ADMs could be emplaced by military engineers or special forces teams, then detonated on command or by timer to create massive obstructions. By destroying key terrain features or choke points such as bridges, dams, mountain passes and tunnels, ADMs could serve to create physical as well as radiological obstacles to the movement of enemy forces and th ...

Permissive Action Link
A permissive action link (PAL) is an access control security device for nuclear weapons. Its purpose is to prevent unauthorized arming or detonation of a nuclear weapon. The United States Department of Defense definition is: The earliest PALs were little more than locks introduced into the control and firing systems of a nuclear weapon, that would inhibit either the detonation, or the removal of safety features of the weapon. More recent innovations have included encrypted firing parameters, which must be decrypted to properly detonate the warhead, plus anti-tamper systems which intentionally mis-detonate the weapon, destroying it without giving rise to a nuclear explosion. History Background Permissive action links were developed in the United States in a gradual process from the first use of atomic weapons to the early 1960s. In 1953 the United States Atomic Energy Commission and the Department of Defense signed the ''Missiles and Rockets Agreement'', which paved t ...

United States Atomic Energy Commission
The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb. An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the Ener ...
