D'deridex class

## SPACECRAFT CLASS

A D'deridex bearing the Republic emblem.

The ***Iirhhaedh'rrhiet D'deridex*** or ***D'deridex*-class**, was a type of spacecraft developed by the Romulan Guard in the mid 24th century. It was named in honor of D'deridex, who served as Praetor of the Romulan Star Empire in the mid-22nd century.

## History

The *D'deridex*-class was the successor to the *Amarcan* and *Praetor*-classes. Improving upon some weaknesses present in the earlier vessels, the class was designed to be larger than any Starfleet or Klingon starship of the time.

The warbird saw great success and by 2370 comprised the bulk of the Romulan Star Navy. They also participated heavily in the Dominion War.

The warbirds were still in heavy use by the Star Navy and Tal Shiar in the early 25th century. However, many of the vessels had fallen into the hands of the Reman Resistance and the newly formed Romulan Republic.

### Derivatives

The Republic military would take inspiration from the *D'deridex*-class in the development of its own *D'ridthau* and *D'Khellra* subclasses.

Named for a famous military figure, the *D'ridthau*-subclass was more compressed than the original *D'deridex* and had a longer nose, but was still one of the largest warbirds of the time.

Following the success of starships deployed with Operation Delta Rising, Romulan engineers began the Tagor Program to update core warbird designs. The project sought to combine the best of Romulan construction with new ideas from Republic engineers and technical improvements suggested by the Republic's allies. The *D'Khellra*-subclass, named for a famous warbird captain, was the first warbird to come from this undertaking.

## Technical information

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

The *D'deridex* class's large size made the vessels intimidating and highly adaptable.

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.

### Class variations

While some fleets held *Dinæs s'Daihlsam* (Right of Standard) that allowed them the use of custom liveries on their vessels, the biggest variation among *D'deridex* warbirds was hull coloration. The color varied depending on where the ore used in the metals for the hull was mined and smelted. Emerald (*ehrie*) was reserved for Command fleets and ivory (*Aye s'Fvillha*) for the *Tal'Prai'ex*, with gray, gray-green, and brown-hulled warbirds disbursed amongst the Senatorial fleets and client state defense forces.

### Tactical systems

A series of nullifier cores worked in concert with the *D'deridex's* cloaking device to prevent the detection of the design's artificial quantum singularity core.

The armaments of the warbird included fourteen Type-IX plasma-disruptors, natively divided as six *S'thavrien*-class heavy disruptor banks and eight *Nalaru*-class light disruptor banks, and four launch tubes.
