Definition

Noun: 1. A small, computerized, heat-seeking missile designed for ballistic missile defense: "Brilliant pebble" is a code name for a conceptual weapon system. It refers to a small, autonomous interceptor missile that uses sensors and onboard computing to detect, track, and collide with incoming enemy missiles, primarily by homing in on their heat signature.

Usage Examples

• Noun:
  • The Strategic Defense Initiative proposed deploying thousands of brilliant pebbles in space.
  • A brilliant pebble was designed to be a cost-effective, space-based interceptor.

Advanced Usage

• Historical/Technical Term: The term is almost exclusively used in historical discussions of Cold War-era missile defense concepts or in technical military literature. It is not used in everyday language.
• Conceptual System: Often used to refer to the overall defense strategy or constellation of many such interceptors, not just a single unit.
  • The brilliant pebble concept aimed to create a defensive shield.

Variants and Related Words
