Re: Ring and Sphere worlds
The smallest ship that can carry a spaceyard is a Cruiser; so you can either:
1) Build 11 (or 21 for a sphereworld) Cruiser-sized spaceyard ships, send them to a star & build the various starbase-sized components (BTW - I'd send one ship there to start the ringworld/sphereworld generator first, since it takes almost twice as long to build as the other components).
2) Send 1 Cruiser-sized spaceyard ship, build a space station with a spaceyard component (lower maintenance than the cruiser Version); then start building more space station spaceyards, which can then be used to build the ringworld/sphereworld components.
