Video game spacecraft design turnaround plate, photorealistic CG concept art, on a plain light grey background. A battleship built around one giant spinal railgun: the twin rails run the full length of the hull and open at the bow, heavy armour wraps around them, capacitor banks along the sides glow blue, two rows of broadside turrets, a command tower aft, four huge engines. Original design, not from any film, series, anime or game. No logos, no insignia, no flags, no text markings, no numbers on the craft. Real size 1100 m long, 160 m wide, 140 m high. Layout: big orthographic side view across the top, front view, rear view and top view below, and a 3/4 front hero view; callouts naming the main parts and dimensions in metres; material swatches (hull paint, bare metal, heat-scorched metal, glass, engine glow). Rich believable construction detail: panel lines, hatches, thrusters, vents, light wear. No other text.
