I don't think Frontier has quite thought out just how awful it is to have mixed economies
That seems to be a relatively common sentiment I’m seeing in regards to this. Though of course confirmation bias could be playing a role here because that’s what
I think has happened here. Not enough or no consideration to what happens when certain or most economy types get mixed, especially in the presence of a necessity to build security-related infrastructure (to some extent, even just to keep it neutral/slightly positive).
Planetary/stellar body economies are still an even worse offender here. They should not be so completely hard-locked to stations with a basic colony economy, and/or not be so excessively powerful.
Specially if you have to build many military facilities to do it.
The system I am looking at developing currently (extraction/refinery) with how I intend it to be set up does need at least 1 security station, two (T1 medium) military settlements, and some government installations to break even or be slightly positive in security. So there is no way around them.
In my intended build scenario, it would look like this in the end for structures which reduce security :
Asteroid base - 1x, -1 sec
Commercial outpost - 3x(primary included), -3 sec
Civilian [orbital] outpost - 2x, -2 sec
T1 Medium mining settlement - 7x, -7 sec
Mining outpost installation - 3x, -3 sec
Refinery hub - 14x, - 14 sec
T3 orbital - 1x, -3 sec
Planetary ports - at least 1x T1 civilian, possibly a T3 instead of second T1, so -4 to 5 sec
Coriolis orbital - 1x, -2 sec
So, I’d be looking at, at minimum, a security level of -39. I don’t think I can just ignore that and say it’s fine. That tends to end up in a room filled with flames, and a dog with a teacup. I would also
like to have it as a high security system, not a pirate’s dream looting spot. My intended solution…
1x Nemesis Military outpost (+2)
1x relay station(+1)
2x T1 medium military settlement (+8)
3x security station (+27)
7x comms installation (+7, this might be a bit overkill but I can still change it)
1x government installation (+2)
According to the spreadsheet I get a positive of 17 security with that setup. Some agri settlements on a moonlet (2 C a*) to cover standard of living more and a space farm elsewhere, too.
*Also planned to hold third security station. Since moons of main planets don’t have strong link influence (currently) on their parent body, this shouldn’t cause a strong link on the orbital port of the moon, right? Otherwise I will have to rethink the plan slightly and put it elsewhere, or replace with government installation. +10 should be enough to get a high security rating anyway, if I understood correctly how things work in that regard.
