It also seems that a vehicle type that uses the Requirement Pct Fighter Bays, Requirement Pct Colony Mods and the Requirement Pct Cargo does not need to be told to use a Comp Spaces Per One number. Because it will uses the Requirement Pct to add the component.
Example:
Vehicle Size Data File.
Light Carrier
Requirement Pct Fighter Bays := 40
AI Design Creation Data File.
Carrier
Majority Comp Spaces Per One := 0
Majority Comp Ability := Launch/Recover Fighters
