Combat Mechanics

I think one thing the designers may want to consider is look at the effects they want to achieve.

For defence you could have the following I'm borrowing from Real Life navies.

Point Defence (short range missile interception)
Missile Interceptors (medium range missile interception)

Electronic Countmeasures (affect missiles tohit chance)
Chaff/Flares (affect missiles tohit chance)

I would suggest that given the "function" of the last three (ECM,Chaff and Flares) is the same you would just lump them as one piece of equipment (Counter Measure Systems). Now obviously you could have better grades (Grade 1, Grade 2 etc) but you get the idea.

Same goes for point defence and interceptor missiles. Again, you would have multiple grades (Point Defence 1, 2...n)

The main point is you don't get cluttered with lots of gizmos that do the same thing.
