The ISS Cooper was a Terran starship that was in service to Starfleet in the mid-23rd century. The ship's commanding officer was Captain Spoeneman.
This ship came to the assist of USS Discovery (mistaking it for the ISS Discovery) when it was attacked by a Vulcan cruiser in the asteroid field of Porathia. After the Cooper chased the cruiser from the Discovery, it returned to inquire on the status of the latter. After being satisfied with the answers it received, the Cooper returned to its mission of locating and destroying rebel nests. (DIS: "Despite Yourself")
Star Trek: Discovery The Official Starships Collection issue 9 states that the Cooper was intended to be a Malachowski-class Terran ship; however, due to time constraints, the ship was not shown on screen. The same article also states it has the registry NCC-1669.
