This is a pretty standard 3D modelling strategy, unsurprisingly, called "box modelling". You can create an incredible amount of things with box modelling. Including, obviously, a lot of spaceships. I built several crud spaceship designs with box modelling back in school. The main key advantage, is all of your 'parts' are built off of a single object in the editor, and aligned perfectly.

The other thing though, you can do to a box modelled project, is round all the edges to varying degrees, and end up with something looking much more fluid and amorphous. However, I suspect the results would be far more unpredictable if he through something like that into this script, so it'd be difficult to go there procedurally.

Yeah back when I made 3D models of star trek spaceships (trekkie in your name significant?) that was one of the go-to methods for making the shuttles, smaller craft, borg (obviously), but stuff like Voyager and the Enterprise-E you would often resort to more advanced lofting/spline patch based techniques and work off of a sketch.
