Thats the point I made! Its not a CIWS system but with RAM it would offer a useful level of defence.

Its not a manned mount but remote control. Good for close-in work against small surface targets and overflying jets (Argy/Falkland style)

Niedersachsen, Karlsruhe and Bremen temporarily fitted with 1 30mm Goalkeeper CIWS from 1991 to 1993, all other units also had provisions for Goalkeeper.

Since the RAM system took so long to materialize, these ships spent the whole 1980s without a point defense system, but could have been fitted with the british/dutch Goalkeeper system if necessary. Only 3 ships ever carried Goalkeeper for a potential Persian Gulf deployment in 1991. RAM finally arrived in 1993, giving these ships a very good point defense system.

Ab Frühjahr 1991 wurden aufgrund des Golfkrieges drei Einheiten (zeitweise) mit dem niederländischen Nahbereichsabwehrsystem GOALKEEPER ausgerüstet: NIEDERSACHSEN, KARLSRUHE, und BREMEN. Ab Mai 1993 Beginn der Aus- / Nachrüstung mit dem RAM-Waffensystem, das die NIEDERSACHSEN als erstes Schiff erhielt.
