Space platform to park in orbit on Aquilo that products green, red, and blue circuits so you don't have to import them. Also produces iron, copper, steel, and plastic, storing a buffer of each in the cargo hold so it can be dropped to planet as well if needed. Produces its own ammo and rockets and is self sufficient.
This is late game design and uses many legendary products along with fusion power. You can downgrade and instead make several copies of the whole platform if you lack the legendary parts. If you are downgrading, I suggest focusing on productivity modules to make the most use of limited chunk supply when parked.
Will operate on solar over Nauvis or Vulcanus without the fusion power. You can delete solar once fusion power is built, and delete the thruster once parked, though it does not get in the way.
