IRW Deranas

The IRW Deranas was a Romulan warbird in service in the late 24th century. During the mid-2360s, the Deranas was commanded by Commander Tomalak. (CCG: Second Edition)

In 2366, the Deranas violated the Romulan Neutral Zone in order to rescue the crew of the Talon-class scout, Pi, which had crash-landed on Galorndon Core. (TNG episode: "The Enemy")

A few months later, the Deranas was one of several warbirds that remained near Nelvana III and were part of the plot to reveal Admiral Alidar Jarok as a defector. (TNG episode: "The Defector")
