Update: Working on Balance

I'm currently finishing up the Rebel Navy with a November beta Space only release as my target launch for the mod.
While doing that I have started to think about balance, especially for ships where I don't have canon values for various stats.
The following chart lists where I am currently at in terms of baselines by ship/station class:

Class	Build Time	Population Value	Maintenance Value	AI Power	Armour	Shields
Space Station	420	0	0.1	2000	100	5000
Battle Station	360	0	0.1	3500	100	7500
Star Dreadnaught	300	10	2.5	7500	125	12500
Star Battlecruiser	240	7	0.5	1500	100	5000
Star Destroyer	180	5	0.25	500	75	3500
Frigate	120	3	0.05	150	50	1000
Corvette	60	2	0.025	75	25	500
Starfighter	30	1	0.01	5 * Number of Ships in Squadron	5	50

Legend

• Class: The ship or building class.
• Build Time: In Seconds.
• Population Value: How many population units the vessel takes up. Older and more inefficient ships like the Dreadnaught-class Heavy Cruiser would have higher values than the baseline.
• Maintenance Value: Taken from your income, the higher your maintenance the less money you'll have for new spending. Older or more ineffecient ships in a class would be higher than the baseline.
• AI Power: This is how the AI calculates how powerful a unit is for battle auto-resolve and for determining if a force is powerful enough to launch an attack.
• Armour: A general number, I have these setup in the config file and will probably need to tweak this. It works like a damage modifier, +/- damaage based on damage types like laser, turbolaser, missile etc.
• Shields: in SBD

Does this look ok? What are your thoughts?
