One of the common complaints that I've seen is that Military starbases are not all that useful for planetary defense; one can simply bypass the starbase and invade the planet with no real issues. This mod aims to change that by adding Planetary Defense to Military starbases, as well as increasing their Hitpoints.
Edit: Updated for 1.02 and nerfed as per my post below.
- A basic Military Ring gives all planets in range +10% Planetary Defense, and adds +50 HP to the starbase (250 HP total for the starbase).
- The Defense Network Module adds another +10% Planetary Defense (20% total), and another +50 HP (300 HP total for the starbase).
- The Sector Defense Grid Module adds another +10% Planetary Defense (30% total), and another +50 HP (350 HP total for the starbase).
With these changes, you now have to deal with nearby Military starbases or else suffer massive casualties and/or total failure to invade. I'm not sure how much the AI upgrades their starbases, but I do know they at least use basic Military bases near their planets.
Enhanced Military SB:
With the "All Starbases Can Mine" mod:
I've also included a version that incorporates the "All Starbases Can Mine" mod by Sorentoft, in case you want a dual-purpose Mining/Military starbase. Pick the one you'd prefer.
Also, you can easily change the specific bonuses it you'd like - open up the included StarbaseModuleDefs.xml, search for HitPointsCap or PlanetaryDefense and tweak the values to your heart's content.
As an added bonus, both mod versions include the fix for the Promethion and Thulium Extractor Modules (they were bugged to enhance mining of antimatter instead of Promethion/Thulium) so they now work properly. (No longer necessary - fixed in 1.02)
