The USS McKinnon (NCC-26989) was an Ambassador-class starship. In 2364, Elizabeth Singh was chief engineer aboard the McKinnon when Ethan Arden came aboard as a mission specialist from the Starfleet Corps of Engineers during a shakedown cruise. Together, the duo overcame a rogue temporal agent attempting to alter the course of history. (Star Trek: The Cantabrian Expeditions: "Perfect Girl")
