i mean as in: you see the ships are civilian, but now obviously refitted for more "illegal" use. No need to use that one shuttle and transport as base or modify them haha. You could think of(i am just shooting ideas at you here):
a civilian personal transport, could be as in like a bus or to move corporate personnel around.
small "car" like shuttles, i picture those as used in sub orbit and now refitted for use in real space.
a new buffallo/taurus/gemini modification.
a refitted colony ship(!), from the very beginning of the corvus sector colonisation, forgotten on a ship scrap yard but now repaired and in use again.
a trash collection ship, think of a very sturdy, venture style, kind of ship, very incognito and perhaps now a smuggle freighter/carrier for them, or that with drones which where originally to collect scrap in the orbit of the planet, but now for attacking other ships.
a firefighting ship, because even in the future you will have fires in cities or on stations in space.
Some kind of space racer pods, because a semi-apocalypse may have happened, people still want to be entertained, and pirates are fond of quick ships.
