Large Container ship with sushi belt logic Might require some tweaking for the front gun ammo Takes a while to populate the sushi belts with asteroids and fuel. You can adjust the rear pumps to higher numbers to move faster, but the current setting is ideal for fuel. (91% efficiency) I left room at the bottom of the sushi belt to add ammo from the cargo bays which can speed up the process of collecting asteroids. Just shy of 900 ammo will populate the belts and turrets.
Has 939 storage slots and enough cargo bays to quickly unload and load with multiple rockets and orbital drop ships. To quickly load/unload make sure your planet has sufficient rocket silos and cargo bays.
