Re: Will there be an explaination for how enterprise can go underwater Yeah, FYI we have no real indication the Galaxy class was built on the Mars Surface. Indeed, the half complete Galaxy spaceframes seen in Relativity would be enough proof they aren't. All we know from that picture is that Utopia Planitia has a ground based facility. We don't know what goes on there. Even if it is construction, we don't know it's Galaxy class ships. It could be shuttles and runabouts.
