“Multiple attached facilities can work together to increase the capacity available and the repair rate on a single ship. The amount of shipyards that will work on a ship is found from the number of shipyards per ship = shipyards / ships (rounded down).”
As this states facilities i assume it applies to planetary starports, landing pads, hangars etc.
But what does "attached facilities" mean?
would the the facilities have to be built touching each other or can they be seperated by roads?
I've noticed there's a "jobs" field for facilities now. Does that mean in future a planet's population must be equal to or more than the jobs on the planet?
Repair rules are still currently being discussed, and repair will not be out for a long time, so any answer you receive now will not be final until the rules are updated a short period before they are implemented.
The Jobs field affects the planet's employment rate, which has an effect on facility income right now.
