Many hypothetical doomsday devices are based on the fact that hydrogen bombs can create large amounts of nuclear fallout.

A doomsday device is a hypothetical construction — usually a weapon — which could destroy all life on the Earth, or destroy the Earth itself (bringing "doomsday", a term used for the end of planet Earth).

Doomsday devices have been present in literature and art especially in the twentieth century, when advances in science and technology allowed humans to plausibly imagine in a definite way about the possibility of actively destroying the world or all life on it (or at least human life). Many classics in the genre of science fiction take up the theme in this respect, especially The Purple Cloud (1901) by M.P. Shiel in which the accidental release of a chemical gas kills all people on the planet. (Weart 1988)

After the advent of nuclear weapons, especially hydrogen bombs, they have usually been the dominant components of fictional doomsday devices. RAND strategist Herman Kahn proposed a "Doomsday Machine" in the 1950s which would consist of a computer linked to a stockpile of hydrogen bombs, programmed to detonate them all and bathe the planet in nuclear fallout at the signal of an impeding nuclear attack from another nation. Such a scheme, fictional as it was, epitomized for many the extremes of the suicidal logic behind the strategy of mutually assured destruction, and it was famously parodied in the Stanley Kubrick film from 1964, . It is also a main topic of the movie Beneath the Planet of the Apes, in parallel with the species extermination theme. Most such models either rely on the fact that hydrogen bombs can be made indefinitely large (see Teller-Ulam design) or that they can be "salted" with materials designed to create long-lasting and hazardous fallout (e.g. a cobalt bomb).

Alleged implementations

A number of nations continue to maintain nuclear stockpiles in the thousands of warheads which could be potentially used to a similar end (see, e.g., the idea of nuclear winter), although these are not doomsday devices in the strict sense.

The Perimeter system developed by the former Soviet Union is occasionally cited as a doomsday device (the “dead hand”), but in fact it is only a communications continuity system designed to keep missile defense operable even after massive infrastructure damage.

In popular culture

Use of this concept for humor purposes has occurred several times in popular entertainment.

Use of multiple nuclear weapons causing the destruction or virtual destruction of all life on Earth as a type of doomsday scenario has been used in several fictional stories including Nevil Shute's On the Beach and David Graham's Down to a Sunless Sea.
