Re: It's almost 5AM and I'm thinking about Space Combat
I think if you look through TE and STK you'll find that ship weapon systems don't have range modifiers. That's left up to the targetting system that is purchased for the vessel. I believe in TE the standard targetting systems are written up as +4, +8 and +12 vs. Range Modifier but, of course, you can make them whatever you want.
As I understand it, the scale is 1" to 1", so a Dreadnaught wouldn't even fit on your standard battle mat. However, how much maneuvering and jinking is one of those ships going to do during a fight? Is it important to have them on the map at all? Capital ship to capital ship battles are basically slugfest where they hurl as much of their battery at each other as they can. range isn't really a factor considering the DCV penalties for size as well as the targetting system PSLs.
Obviously, fighter combat works better on a battle mat. Given the average SPDs and Flight of most fighters from TE, you can very easily dogfight at the 1" to 1" scale, or at least make it a 2 for 1.
