The D'deridex-class (or B-type or Warbird-class) battlecruiser was the pride of the Romulan fleet in the mid-to-late 24th century.

They were registered as a class 5 vessel. (DS9 video game: Dominion Wars)

The class was named after Romulan Praetor D'deridex, who held office during the late 22nd century. (ENT novel: Kobayashi Maru)


The D'deridex-class was the successor to the Amarcan-class warbird of the 2340s and the War Eagle-class, enlarging its double-hull design and correcting some weaknesses which had become evident in the older vessels. The class was designed to be larger than any Federation or Klingon starship of the time. (TOS novel: Vulcan's Heart, ST reference: Star Trek: Starship Spotter)

The class was extremely successful and soon found its self making up the bulk the Imperial Romulan Fleet. D'Deridex-class vessels represented the Romulan Star Empire in numerous incidents and historical events and the class participated in many engagements in the Dominion War. (DS9 episodes: "Tears of the Prophets", "What You Leave Behind")

The D'deridex Advanced was a variant of the basic D'deridex-class starship. These ships were upgraded at Orias III by the Tal Shiar and joined with Cardassian Keldon-class ships for an invasion of Dominion territory in 2371. The IRW Belak was an example of this variant. (ST:CCG: The Dominion)

Vessels of the class were still being constructed in the late 2370s, before being phased out in favor of the more powerful Mogai-class warbirds in the 2380s. (TTN novel: Taking Wing)

By 2409 many of the remaining D'deridex-class warbirds had fallen into the hands of Obisek's Reman Resistance. Others were controlled by the Romulan Republic. (ST video game: Star Trek Online)


Like most Romulan vessels of the 24th century, the D'deridex class is powered utilizing an artificial quantum singularity and is fitted with a cloaking device.

The D'deridex class's large size makes the vessels more intimidating, but also makes the class highly adaptable. The vessels are primarily meant for military purposes but can just as easily take on role of a science vessel or supply ship. (ST reference: Star Trek: Starship Spotter; WizKids module: Attack Wing)

This class of ships were known to possess research labs, reverse engineering terminals and intelligence gathering equipment making them capable of a wide variety of operations; both in the fields of combat and covert missions. (TNG video game: Starfleet Command III)

At one time, it was believed these vessels only carried a crew of 622 Romulans. (TNG video game: Echoes from the Past)
