This is really the air game approach, using fixed guns. It works, and works
well, for what it's trying to simulate, but real turrets with, say, 150
degrees traverse in the (ship's) horizontal plane, a max elevation of 140
degrees and max depression of 10 degrees (which is a rough guess at the firing
arc of something like the side phasers on the original ST Enterprise), are
more of a
problem --
how do you determine, in a reasonable time, if the Klingon coming up behind
you is in arc?

The Astromechia system sounds interesting. I presume that weapons can have
multiple arcs (like, say, Forward/Port/Up/Down?) -- is this right? How
do they
--_do_ they? -- handle relative attitude?
