The Vidian class was a type of heavy starbird that saw service with the Romulan Star Navy during the 24th century. It entered service in 2362. (Ship Recognition Manual, Volume 5: Starships of the Romulan Star Empire) The Vidian resembled the smaller Neh'vor-class. Its command hull differed from that vessel, it had a broader main hull and its wing pylons did not sweep forward as much.
