Background information 

Seen only as an aft view in the opening credits, this model would inspire the "Warp Delta" starships, also seen in both the prime and mirror universes. 

Model and sequence were constructed at Foundation Imaging, whereas the In a Mirror, Darkly version was modified at Foundation's successor, Eden FX. (episode credits)

According to Issue #124 of the Star Trek: The Official Starships Collection, there was only one Emmette-type starship, which was used as a test vehicle. This type was approximately 130 meters in length, had a maximum speed between warp factor 1 and 2, and an approximate crew complement of 20 or 30. With advances in warp technology, this type was replaced by Starfleet with the Warp Delta type starships.
