As far as table changes for one, you could start by adding shield hit count figure for the Defiant. At first I thought the model didn't have a shield mesh, but then I looked at it in Modview and sure enough, so I suggest you make the change. Also, when you compare its top speed of 55 to the 70 of the Akira, I think that either the Defiant should be faster, or the Akira should be slower... unless these are the official figures, in which case I'll shut ip. I was noticing that you also made the forward torpedo and phaser cannon firepoints both in the conventional primary/secondary sense, as well as in the form of turrets. Was the inclusion of the primary/secondary system to allow this to be a player-flyable ship in the future, or were they required for it to use the bomber AI? I am also a little puzzled by your use of the forward probe launcher as a fire-point, unless its intented to line up with the deflector dish above as I suggested on the Galaxy. If this is the case, I applaud it, since once we have some dominion attack ships, we could re-create the DS9 episode "Starship Down"... to some degree. Additionally, I think the firepoint for the dorsal phaser beam should be moved forward a bit, since it should be at the center of the upper ring. All in all however, a good looking design.
As far as some of the other models are concermed, you should work on your subsystems. Take the Akira for example... it does in fact have a deflector dish and likely a weapons control subsystem, so I think you should be less concerened with bussard collectors, and more with the above-mentioned subsystems.
On a whole, I think it would simplify our design if we could use a single weapon turret for a phaser strip, rather than having so many accross its firing arc, but I guess that's beyond our grasp. Something which has just come to mind however, are the multi-turrets. The Orion design has those deck gun style turrets, with 3 barrels, each mounting a weapon. If you look in the table file, it lists these weapons as multiple weapons of the same turret, rather than separate turrets. I'm not sure about this, but I think one of the side effects is that the AI will only fire one of these at a time. Perhaps, if there isn't a upper limit to how many mounts you can have on the same turret, we could merge say the 11 or 12 turets in a single phaser strip into multipe turrets on the same mount. That way the AI will only fire one of them at a time, and you won't have multiple beams firing from the same array. Just a thought... whether it holds water or not is open for discussion.
