yellow submersible 3d model

A single small deep-sea research submersible, side view, floating. Entire hull painted solid bright safety yellow like the classic submersible Alvin. Compact rounded hull with a large circular front viewport window with a dark steel rim, one bright round headlight inside the front, small side thrusters, a short rear propeller with a protective ring, a low sensor mast on top, small tail fins. Hard-surface industrial design, refined and elegant, not cartoonish, not a toy. Matte yellow paint with subtle panel lines, glass viewport, brushed dark metal details only on rims, rails and bolts. No base, no water, no background, no text, no other objects. Clean topology.
