Arsenal Ship Idea (WIP)

I wanted to give drawing an original design a go, so here’s a kind of rough sketch of what I’m thinking of. She’s based on concept art of a US Navy arsenal ship (floating missile platform) back in the 1990s. I imagine she’d be a main fleet ship of the Eagle Union, but I don’t know what name she’d have since she was never given a name by her designers other than BB-72.
