From FEInfobase
Intrepid Class starship commanded by Lieutenant Johnson.The oldest serving member of the now infamous Johnson family of Earth. A virtual identical twin to USS Voyager, it served as Admiral Cash's flagship in the Renegade Armada before the stolen Venture Star was finally finished and ready for use.
By 2406, it had been reintegrated into Starfleet following the Battle of Sol and was commanded by an unknown woman of possible Maori descent and aided in the rescue of the Cerberus following their awakening near Mars after an alteration on Niflheim Station. ("The Hellhounds Dossier")
