About the Franklin: Spoiler: Franklin I was told that even though the ship has an NX registry prefix, it is not a class ship. So what does the NX mean, then? I mean, obviously it can't be the class name, since the Franklin is clearly not of the NX class as the NX-01 Enterprise is (even though they kind of look alike). Is the Franklin one of many prototypes (of whatever this class is) that were constructed, but the class was named after one of the other prototypes? Or is it the ONLY ship of its class, thus making a class name superfluous? Those are the only other explanation I can think of right now.
