It was posted on another thread that the idiots in many of the ports currently will not allow an armed vessel to enter their docks.
That's true, which is why most vessels go unarmed. At best they have fire hoses around the ship with which to repel boarders.
Hey, that's an opportunity. Build a very high-pressure water cannon system with enough mounts to cover all aproaches to the ship. Water inlets front and back, a couple V-12 diesels to run the pumps. Remote-control from the bridge with night/day cameras. A serious water cannon has enough pressure to break bones and rupture internal organs on impact.
We'll call this the "Enhanced Firefighting System" if the pansy ports have problems with it.
