USS Cooper
For the mirror universe counterpart, please see ISS Cooper.
The USS Cooper was a 23rd century Federation starship operated by Starfleet.
Around the time the USS Discovery was transported to the mirror universe, this ship was undergoing a refit. (DIS: "Despite Yourself")
Star Trek: Discovery The Official Starships Collection issue 9 states that the mirror universe Cooper was intended to be a Malachowski-class ship with the registry NCC-1669, implying this is also true of the prime universe counterpart.
