The '''Goalkeeper CIWS''' is a Dutch [[close-in weapon system]] (CIWS) introduced in 1979. It is an autonomous and completely automatic weapon system for short-range defence of ships against highly maneuverable missiles, aircraft and fast-maneuvering surface vessels. Once activated the system automatically undertakes the entire air defence process from surveillance and detection to destruction, including the selection of the next priority target.
