Alright, that's definitely Enterprise-F. Similar design to Voyager but has more in common with Enterprise-E. Almost like a hybrid design of the two.
I guess -F was designed by a fan during a contest for Star Trek Online, so they basically yoinked the design for this show.
Still wondering what the other ship earlier in the trailer is (the one that seems to be the main ship they're using). I compared it to Enterprise-C (Ambassador) and that's not it, the center warp thing is more like Excelsior. So that might actually be something new. Whatever it is, I like its design more than Enterprise-F's. Maybe it's Enterprise-G?
