Guided Penetration Bomb

The Guided Penetration Bomb (GPB) is a special weapon of the Ace Combat series. The bomb is designed for a guaranteed destruction of important heavily defended targets at medium range. This is the most powerful weapon from air-to-ground weapons intended for destruction of single targets. Once dropped, this bomb glides toward a target with a lock-on. It has a small radius of explosion, but inflicts heavy damage.
