The Tirethi-class was a type of starship used by the Romulan Star Empire's Star Navy in the 24th century. The Tirethi-class was a far scout design. (Last Unicorn RPG - The Way of Dera module: The Romulans)
- This class presumably included a prototype ship that would be named Tirethi, although no such ship was mentioned.
