Sheldon Dynasty Colony Ship

Sheldon Dynasty Colony Ship from Judas Unchained by Peter F. Hamilton.

"The assembly bays are putting together complete compartments; that's why they're so large and complex. These are like spheres that have six airlocks. All you have to do is stack them together on top of a hyperdrive section, and you can have any size ship you want. It's the ultimate in modular design concept."
