The T'kassan-class was a type of starship proposed for use by the Romulan Star Empire's Star Navy in the 24th century. The T'kassan-class was a strike warbird design that, by the turn of the 2370s decade, was expected to enter service in a few years' time. (Last Unicorn RPG - The Way of Dera module: The Romulans) This class presumably included a prototype ship that would be named T'kassan, although no such ship was mentioned.
