The D'deridex-class (or B-type or Warbird-class) battle cruiser 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)

Service history[]

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 have 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 this class were still being constructed in the late 2370s, before being phased out in favor of the more powerful Valdore-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)

Technical specifications[]

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

The D'deridex-class's large size makes these vessels more intimidating, but also makes the class highly adaptable. The vessels were primarily meant for military purposes but could just as easily take on the 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, however the actual crew complement was 1,500 officers and crew, plus troops. (TNG video game: Echoes from the Past, DS9 reference: Star Trek: Deep Space Nine Technical Manual)

Tactical systems[]

The primary directed energy weapons array of a warbird was located in its "head", and consisted of a disruptor array, capable of firing both beams and pulses, which also appears to have been shared with a torpedo launcher. (DS9 episode: "The Die is Cast", TNG episodes: "The Defector", "Face of the Enemy", "Timescape"; VOY episode: "Message in a Bottle")

Some warbirds were also known to have been equipped with phasers. (TNG episode: "Contagion")

Three additional weapon arrays were located, one each, along the top of the upper "neck" support, along the bottom of the lower "neck" support, and at the tip of the "nose". (TNG episodes: "Contagion", "Unification II", DS9 episode: "What You Leave Behind")
