Video game spacecraft design turnaround plate, photorealistic CG concept art, on a plain light grey background. A huge fleet carrier mothership: a long flat-topped hull with two long hangar bays opening along the sides (glowing inside), a command island tower, defensive turrets, a forest of antennae, a massive engine section. 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 1400 m long, 380 m wide, 220 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.
