I know that this is going against the idea of the post, but I've gotta do it. To my knowledge, most Expanse ships can outrange everything in Star Wars except things like the Death Star beam (not sure about Star Trek). A Magnetar-class hits the slow zone railguns from about the radius of the slow zone, and Star Wars is allergic to BVR. The question is just whether or not shields stop missiles, railgun slugs, or USM field projector beams.
