My latest and greatest space platform, capable of travelling at 580/560 km/s continuously with no downtime. Power is generated by 400 MW fusion power plant, but there is space left for fission one if you haven't researched fusion yet. For protection it has gun turrets set to target small and medium asteroids, rocket launchers and rail guns, set to target big and huge asteroids. It makes around 180/m red rockets and 20/m rail gun shells.
Before going to Aquilo or deeper leave it in Nauvius orbit or make a few runs to inner planets and let it stock up on ammo. Collectors have their filters set depending on loop belt contents, you can change the amount by adjusting values in constant combinator. There are also a few decider combinators determening if any resources need to be dropped off in order to not stall production of certain resource.
