I think they may need to re-edit the section on Adjustable Hulls.
"ADJUSTABLE HULL Large sections of the hull consist of bands and strips that change the hull’s overall shape, making the ship have the same outline as any other ship of the same tonnage, hull configuration, hull options and external systems, including mimicry of attached modules, although these are non-functional."
This is the exact quote, but what I think they meant to say was this.
"ADJUSTABLE HULL Large sections of the hull consist of bands and strips that change the hull’s overall shape, making the ship have the same outline as any other ship of the same tonnage. Hull configuration, hull options and external systems, including mimicry of attached modules, are possible although these are non-functional."
My question about the maneuver drives is due to being able to cover them with hull plates thus reducing their signature.
