Space Dock 7 was designed to serve the fleet as a repair facility whilst being capable enough to keep up with military speed. Her dimensions are dictated by her "clientele" of ships - namely the Exelion Frigate, Jotunheim Corvette and Takeshi Maru Missile Cruiser.
This MOC was greatly inspired by Dunechaser's fantastic UEF Ship Recovery Vessel. Go check it out.

The superstructure up close, with the bridge above (flanked on both sides by the quantum torpedo launchers), and the larger-windowed viewing gallery below it.
Interesting idea to have a dock that is mobile. It's something I'd never do though. I'd have maneuvering thrusters at the very most, but no engines, unless they were to stop the docks from re-entering an atmosphere, which would be bad for business...
