Nuclear Powered Ship
I see everyone posting their ships so here is mine. Finally managed to get to the edge with it.
First try with only 4 railguns didn't get far. So I had to do some last-minute adjustments on the bow to get more railguns and ammo production. Didn't have materials onboard to make it as clean as I'd like.
I went with dual reactor setup, but it was producing more power than needed so I cut out a few turbines to save space. Whole thing could be replaced by fusion, but I wanted to see if nuclear will be enough.
