This spaceport and attached spaceyard can service, repair, and construct ships up to 30,000 tons (SM +11) internally; as with its larger cousin, other ships – and anything too big to fit inside – dock outside using the external clamps. It is a donut-shaped station that rotates to provide artificial gravity, with a large solar-panel array to provide power.

These stations are usually found as the main station in secondary systems that do not have a class V.
