Inspired by the Homeworld Mothership
You've missed the hangars for the fighter swarms to dock before jumping. I think you need a lot more engineering spaces as well as thinker armour.
Still trying to figure out how to have "fighters" that are able to be built on the ground, because I know it's anything under 500 tons... but I have ships that are like, 350 tons o.o
For it to be a fighter it needs to have a fighter engine. Research fighter engine under power and propulsion, then when designing an engine in the drop down that lets you pick military/civilian there will be a new option, fighter.
