The Praetorian-class was a type of starship proposed for use by the Romulan Star Empire's Star Navy in the 24th century. The Praetorian-class was a dreadnought 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 Praetorian, although no such ship was mentioned.
