Weapons in Science Fiction - Weapons of Mass Destruction

Weapons of Mass Destruction

Nuclear weapons are a staple element in science fiction novels. The phrase "atomic bomb" predates their existence, and dates back to H. G. Wells' The World Set Free (1914) when scientists had discovered that radioactive decay implied potentially limitless energy locked inside of atomic particles (Wells' atomic bombs were only as powerful as conventional explosives, but would continue exploding for days on end). Cleve Cartmill predicted a chain-reaction-type nuclear bomb in his 1944 science-fiction story "Deadline", which led to the FBI investigating him, due to concern over a potential breach of security on the Manhattan Project.

The use of radiological, biological and chemical weapons is another common theme in science fiction. In the aftermath of World War I, the use of chemical weapons, particularly poison gas, was a major worry, and was often employed in the science fiction of this period, for example Neil Bell's The Gas War of 1940 (1931). Robert A. Heinlein's 1940 story "Solution Unsatisfactory" posits radioactive dust as a weapon that the US develops in a crash program to end World War II; the dust's existence forces drastic changes in the postwar world.

A sub-genre of science fiction, post-apocalyptic fiction, uses the aftermath of nuclear or biological warfare as its setting.
