doomsday devices

World-ending weapons

Doomsday devices are hypothetical weapons capable of destroying all human life or rendering Earth uninhabitable.

The concept appears in Cold War–era fiction and strategy discussions, often as a deterrent so catastrophic that no rational actor would trigger it: The film imagined a Soviet doomsday device that would automatically launch if attacked.

The term extends to any system designed to ensure mutual destruction.
