ISS Cooper

In the mirror universe, the 'ISS Cooper (') was a Terran Empire starship, a vessel in Imperial Starfleet service in the 2250s decade. 

Service history
In late 2256, the Federation starship USS Discovery (NCC-1031) jumped to the mirror universe by way of its spore drive. In an asteroid field near Porathia, the Discovery came under attack by a $𝜇$ rebel cruiser, and received assistance by the ISS Cooper. Quickly catching on to their predicament, the Discovery's crew acted like Terrans to stave off an attack by Captain Spoeneman, who then had his ship resume the search for rebel nests.
