This is the main starship from the "Operation Rimfire" Mekton adventure. It's internal worklngs include a gravity wheel up top, a "carousel"-type mecha hangar below, and an electromagnetic launch channel. Not the most anime-looking starship design ever, but to be fair, I was looking at a lot of Project: A-Ko when I drew it. The space stations and such in that OVA are coooool. Anyway, this picture is copyright and everything R. Talsorian Games, no infingement, etc.
(Full disclosure: I didn't make the starfield in the background. I found it via Google Images and tweaked it.)
