SeaRAM Anti-Ship Missile Defense System
The SeaRAM is supposed to be able to shoot down incoming anti-ship missiles before they hit the ship, the same thing the Phalanx system was supposed to do. I would think using missiles instead of bullets should give you better range. You might be able to reach out a couple of miles with bullets, but missiles might give you ten times that. You are limited by the number of missiles you have, but the Phalanx has a limited supply of ammunition. It's large, but it's still limited, and it uses it at a prodigious rate.
