Since the railgun came out, I used huge ships mod to make this.
Its based of the German Railway Gun from WW2, the Schwer Gustav. Now I want to know, who else has some railgun ships that only use railguns as their main weapon.
(P.S. This ship has no point-defense, so don't start using it until you have some support and defensive ships. Don't read this extra bit if you aren't going to use this ship.)
