So, everyone is sharing their ships, I'd like to share mine.

I call it the "Atomic Roamer".

It's laid out as a square, which I find to be most efficient after many iterations. I use an outer belt track to both feed the guns and also move astroid pieces around.

From there I use a series of crushers to crush specific asteroids and put the resulting component (ice, carbon, iron ore) on it's own belt loop. I redirect bonus asteroids into the neighboring crusher to prevent sushi belting.

Iron ore and carbon get the first splitters to ensure they get priority access to the belt to make fuels.

Then the iron ore goes down into an ammo factory to create red ammo for my guns, which gets buffered/stored in the the ships storage.

I also include a circuited nuclear reactor with a few turbines to allow me to use modules on the ship, the blue tier solar panels "usually are good enough" but go back and forth from Fulgora, they're often not. Also, waiting in Fulgora orbit is sometimes painful on just solar. Also, I said fuck it, and decided to put a nuclear reactor on my ship because "why not?".

It has a ton of cargo space to be my space hauler and beats the pants off my last iteration of spaceship.

Only down side is water is slow to fill, which is why I have an egregious amount of buffer on it, since the ship primarily runs on ice when it's full out. It generates 44Mw on Nauvis 220mj of battery power which I stuffed in all the empty areas. It carries a dedicated 100k steam for backup, a dedicated 25k water for the reactor, and 20 fuel rods at all times. Interrupts on these circuits do most of the work for me.

The only thing I ship is copper because it's 1 rocket for 1000 copper, which is no big deal; so I can craft my ammo on board. I have also considered setting up a request to speed things up for red ammo, but meh.

Obviously this ship wont make it further than the first three planets, but she chooches and with the modules on board she refills pretty quickly. Most of the water generation occurs during flight as you would expect, so that's where my tanks get the most input. It's almost capable of doing a full lap from Nauvis to Volcanus, to Gleba, to Fulgora, and back to Nauvis; but it runs out of fuel and the engines drop to about 50% in between Fulgora and Nauvis. I don't consider this a bug though, because I didn't build her to run laps, I built her to do work, and the amount of time she's in orbit doing work, she refills.

Thanks for reading!
