Driver

I decided to do a few of my hyper-futuristic spaceships.

Here we have the driver A 3Km long space folding city. The driver ships provide FTL propulsion to the rest of the ships by enveloping one or more of them in their own bubble of space-time.
These ships are rarely seen as they stay in a self contained space-time envelope nearly all of the time.

The preview seems to have some jpg artifacts that I can assure you, the full size does not.
