Nuclear weapon design. Appearance. The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test. Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package [ 1 ] of a nuclear weapon to detonate.
A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible ...
Nuclear disarmament in international law. The United States is one of the five nuclear weapons states with a declared nuclear arsenal under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), of which it was an original drafter and signatory on 1 July 1968 (ratified 5 March 1970). All signatories of the NPT agreed to refrain from ...
Fiveare considered to be nuclear-weapon states(NWS) under the terms of the Treaty on the Non-Proliferation of Nuclear Weapons(NPT). In order of acquisition of nuclear weapons, these are the United States, Russia(the successor of the formerSoviet Union), the United Kingdom, France, and China. Of these, the three NATO members, the United Kingdom ...
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.
A nuclear weapon[a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
April 3, 1992. Designated NHL. August 19, 2008 [ 3 ] The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built. The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II.
Mark 11 – Re-designed Mk-8. Gun-type (8–30 kilotons). Mark 12 – Light-weight bomb to be carried by fighter aircraft (12–14 kilotons). Mark 13 – Improved version of Mk-6 (cancelled August 1954). TX/ Mark 14 – First deployable solid-fuel thermonuclear bomb (Castle Union device).
