They're getting a new boat. (or ship, or whatever they call thse things).
Guided missiles are fine, but I don't see any guns. I'd figure that they might want a few bullet-launchers for close-in defense. Again, I'm no sailor-man, but I've heard that the "Prepare To Repel Boarders" crap is dangerous.
It sure looks angular, doesn't it? I wonder what the radar return on that thing is like.
