The Goalkeeper Close-In Weapon System is an extremely accurate weapon system for close-in defense of ships from high-speed missile and aircraft threats.

The system defeats incoming threats with the 4,200 shot-per-minute GAU-8/A Gatling gun, which fires lethal 30mm Missile-Piercing Discarding Sabot ammunition.

Automatic and continuous threat evaluation and target prioritization are performed by system’s search radar, which relays 2D target information to the dual frequency (X and KA band pencil beam). Extremely accurate and continuous track data at very low target altitudes is provided by the KA band pencil beam. Continuous automatic comparison is made of the signal/noise ratios of the X and KA band returns to ensure uninterrupted tracking in a degraded environment. Anti-clutter and Electronic Counter-Counter-measures features also safeguard accurate tracking.
