Doomsday devices, when used in fiction, are capable of destroying anything from a civilization to an entire universe, and may be used for the purpose of mutually assured destruction, or as weapons in their own right. Examples of such devices include the Death Star from the Star Wars film franchise, the "Doomsday Machine" seen in the original Star Trek television series, or the atomic-powered stone burners from Frank Herbert's Dune franchise.


Planet killers function in a variety of ways depending on the series. Weapons such as the Death Star and the titular ship in Lexx use a directed energy weapon capable of obliterating a planet in moments. In the game Spore, the Planet Buster is an antimatter bomb that is inserted in the center of the planet, causing the planet's core to split into countless fragments. Other weapons, such as the Shadow Planet Killer in Babylon 5 and Covenant warships in the Halo series, render a planet uninhabitable. The Shadow Planet Killer does so by firing missiles which burrow into the planet's core and detonate, causing planet-wide volcanic activity which renders the planet lifeless. Covenant warships use plasma weapons to superheat the surface of the planet; the crust is turned into a glass-like substance rendering it uninhabitable. In Star Blazers, missiles that can destroy a planet (and even a star) with a single hit exist.

Some devices can destroy entire star systems. Nova bombs in Andromeda, the Sun Crusher and Centerpoint Station in the Star Wars novels, and Dr. Tolian Soran's trilithium torpedo in Star Trek Generations, are all capable of causing a supernova, obliterating every planet in the Solar System.

In order to keep him working at his project, a psychologist is brought in to keep him in a delusional state, thinking that she is still alive ... it seems that he is completely fooled by this ruse until the end, where it is discovered that his weapon can (and does) destroy the planet, or at least that is implied ...

Space Battleship Yamato (Star Blazers)

See also: Space Battleship Yamato

Throughout the series and movies, including Rebirth and the recent live action film, the Yamato (Argo) and similar battleships in the Earth Defense Force are armed with a Wave Motion Gun. This weapon of last resort is capable of obliterating entire fleets in one shot, as well as most moon and planetary sized objects. The downside of using this weapon is that it leaves the ship defenseless before and after firing due to the massive amount of energy needed to fire it (except in Rebirth, where the ship could fire six shots without recharging.) Also included would be the Desler (Desslok) cannon, built on the same principle (Tachyon Compression), and the main cannon in Zordar's dreadnaught, which was deployed at the end of season 2.

In the remake Star Blazers: Space Battleship Yamato 2202 the White Comet of the Gatlantis Empire is a planet killing weapon, that captures and destroy a planet's biosphere.

Secondary literature

In his discussion of the tradition of apocalyptic cinema Mitchell exemplifies what the film Doomsday Machine or Escape from Planet Earth characterizes as a "planet-buster"[7] as belonging to the class of "Doomsday device".[8] Secondary literature can also use terms like "planet-cracker"[9] or "planet-busting superweapon".[10]

Science journalism

In the field of science journalism, a 1962 article examined various means "to put an end to the world", concentrating on "Doomsday Bombs".[11]

As astronomer Phil Plait has pointed out, the amount of energy necessary to shatter an Earth-sized planet is extremely large: "about 2 x 1032 Joules.... about as much energy as the sun puts out in a week."[12]
