The ISS Dauntless (NCC-71879) was a Galaxy-class battleship in the Mirror Universe under the command of Robert Wright. It was one of the few Terran Empire ships to escape the invasion of the Klingon-Cardassian Alliance along with the Hood, Venture, Trinculo, and Endeavour. For several years, it hid in a dense asteroid belt conducting hit and run missions against the Alliance. In 2376, it made it to Terok Nor with its task force. With the new ships in rebel hands, the had an even harder time trying to recapture Rebel territory.
