A mid-century science magazine style cutaway of a yellow research submarine, with the hull opened to show the pilot sphere, a tiny lab, galley, bunks, batteries, ballast tanks, and engine room, floating above a seafloor with tube worms and a hydrothermal vent.
A detailed vintage cutaway illustration of a small deep-sea research submarine, drawn in the style of a mid-century popular science magazine center spread: precise ink linework with gouache and airbrush color, slightly aged cream paper texture, and a muted palette of ochre yellow, teal, brick red, slate grey, and deep navy. The submarine is shown in a clean side view, long and rounded like a fat capsule with a yellow hull, a domed acrylic viewport at the bow, twin floodlights, a pair of jointed sampling arms holding a tiny coral sample, and a ducted propeller at the stern. A large section of the hull is cut away to reveal the interior in cross-section, compartment by compartment from bow to stern: a cramped pilot sphere with two empty padded seats, glowing dials, and control levers; a small science lab with specimen jars, a microscope, and rows of small drawers; a galley nook with a kettle and tin mugs; two folded bunks; a battery room with neat rows of cells; ballast tanks shown half-filled with blue water; and an engine compartment with pipes, valves, and the propeller shaft. Thin cutaway edges show the thick layered hull wall. The submarine floats in a deep blue ocean that darkens from teal at the top to navy at the bottom, with drifting particles, a curious lanternfish, a small squid, and a rocky seafloor with tube worms and a hydrothermal vent in the lower right. Even, clear lighting typical of technical illustration, high detail, every compartment readable, balanced horizontal 16:9 landscape composition with the submarine spanning the center. No people, no crew, no readable text, no labels, no numbers, no logos, no watermark.
