Here's the thing about the phalanx. They are the last ditch effort to try and keep you alive, but your going to hurt.

The Russians have a love of putting very large warheads on missiles that fly really fast. Even if the Phalanx isn't overwhelmed, the gun mount has an engage range of 2.2 miles. By the time it destroys that missile, assuming everything went according to plan, that missile has closed to within 1.5 miles and was detonated by the 20mm shells. A close aboard explosion of a 600 pound high explosive is going to cause damage and casualties. It won't sink you but you won't make it out scott free
