v. t. e. Nuclear warfare, also known as atomic warfare, is a military conflictor prepared political strategythat deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result. A major ...
A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low-yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself. The neutron release generated by a nuclear fusion reaction is intentionally allowed to ...
History of nuclear weapons. Trinity- Gadget, an implosion-type plutonium device tested on July 16, 1945, by the United States was the first successful nuclear weapon ever created. It yielded approximately 25 kilotons of TNT. Building on major scientific breakthroughs made during the 1930s, the United Kingdom began the world's first nuclear ...
A tactical nuclear weapon (TNW) or non-strategic nuclear weapon (NSNW) [1] 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.
