Phalanx
I'm probably wrong or this would have been jumped on by now, but isn't ' Goalkeeper ' a more modern system, touted by a few lucky RN ships such as 'Ocean', compared to the original Phalanx CIWS- whichever it is, I'd rather like to have my ship bristling with them if actually going to war, and allowing barrel depression such as to give nuts in speedboats the bad news too...
