Hmm. Things are going well enough... I'm not satisfied with basic stealth though, I want to go for improved stealth and get improved stealth missiles, fighters, and assault shuttles. If we go for the jammers too, I think we can get all that in two research actions?
Improved Passive Stealth: 100 RP
Improved Stealth Fighters: 75 RP
Machine-spirit Jammer: 25 RP
Improved Stealth Missiles: 100 RP
Improved Stealth Assault Shuttles: 100 RP
We're already at the limit for surface installations, so we probably need to make anything else we build underground, not concealed? Which means we can't afford an underground void shield with one construction action... And I really want one of those before things go hot... So, we might want to spend all our BP building underground manufactories, honestly. We can pay them off in two build actions, which we can probably take next turn. So...
Diplomacy/subversion: 1 action
-Mechanicus shooshing and continued subversion and hacking.
Research: 2 actions
Construction: 1 Action
Alternatively, could ditch the assault shuttles and missiles and get a second construction action? Still be a struggle to fit everything we'd want to build in it, but it's at least theoretically doable...
