Designing ship icons for the async space-strategy gameGoal is monochrome single-colour line art, no fill experiments rejected — outline only. Two tiers emerging: simple nose-up silhouette glyphs (rotate along trajectory arcs, legible at ~24px on the orrery map) and a more detailed side-profile concept style for catalogue/build screens (layered hull + superstructure, dorsal sensor mast, aft engine cluster, panel-line section breaks, greebling, with a heavy-outline → medium-structure → hairline-detail line-weight hierarchy). Key construction rule: anything that should be flush must share exact coordinates (engine as part of one continuous hull outline), not two shapes nudged together. Ship classes (8 hulls): Scout (small) — slender needle, Fighter (small) — forked delta; Frigate (medium) — line warship, Capital (large) — flagship; Hauler (medium) — fat ribbed body, Salvager (medium) — forward grapple arms Colonizer (large) — habitat sphere + rotating ring on engine stack; planet claiming. Miner (medium) — forward drill head + side ore hoppers; raw extraction

The image shows a set of different types of submarines silhouettes against a white background. The submarines are of various sizes and shapes, with some being larger than others. The silhouettes are detailed and realistic, giving the image a lifelike quality.
