It is engineered to burrow into the ground or through fortified structures to a predetermined depth before detonating, making it effective against hardened, underground military facilities.
Usage Examples
  • Noun:
    • The military deployed a GBU-28 to destroy the deeply buried command bunker.
    • The GBU-28 is known for its ability to penetrate several meters of reinforced concrete before exploding.
Advanced Usage
  • Technical Specification: The term is often used in military, defense, and aviation contexts to specify a particular weapon system based on its size, guidance method, and intended purpose (penetration).
    • The mission plan called for the use of a GBU-28 due to the target's subterranean hardening.
