<description>Builds a settlement focused on producing and launching small single-use orbital craft. It can make some profit through selling commercial satellites, but when staffed with high-intelligence scientists, is capable of building a constellation of orbital bombardment satellites that can support ground troops anywhere on the plant.</description>

I actually started trying modding exactly due to one idea related orbital bambardment. So maybe once I will test enough of what can be done in other mods and finally make that idea into a mod, then it might end up as something you interested in. It do be quite ambitious, so not sure when it and if it actually happen.

Yep. I've long wanted to make them. They are such an obvious late-game goal and resource sink. Started out trying them as production recipes, that would require a lot of chemfuel, but there's only so much you can fit on a production bench before it all looks silly.

An outpost is a good fit enough for it, though.

IMO, simpler is generally better. Higher perf, fewer bugs, etc. Sure, a fancy building that animates a rocket launch, and maybe even a separate submap like in SOS2 is cool, but just building out an outpost to make them, getting a team of high-int pawns together for the project, etc is fun enough for me for now.

Just wanna make something big my own from scratch, that will fit my playstyle. And to test how far I can go with coding it.
