The Ganum-class was a type of starship used by the Romulan Star Empire's Star Navy in the 24th century. The Ganum-class was a bird-of-prey design that, by the turn of the 2370s decade, had been in service for many years. (Last Unicorn RPG - The Way of Dera module: The Romulans) This class presumably included a prototype ship that would be named Ganum, although no such ship was mentioned.
