This starship was only mentioned in writing.. It was listed in an okudagram graphic Deanna Troi saw on a viewscreen. There is some question as to the existence of the Baton Rouge, as all of the personnel files Troi read were displayed while she was hallucinating and thus might not be real. The starship was listed with other real starships in a ship list from the Star Trek Encyclopedia (4th ed., vol. 2, p. 327).
