The wreckage of a Wanderer-class starship
The Wanderer-class was a class of starship.
In 3189, Cleveland Booker and Michael Burnham found their route through the courier network nearly blocked by the wreckage of an adrift Wanderer-class ship, though Booker's ship was able to morph around it. (DIS: "There Is A Tide...")
The CGI model appears to be a reuse of the Shepard-class.
