Dhelan class

The  Dhelan-class  warbird was a class of starship developed, but not used, by the Romulan Star Empire in the 23rd century. The design was later adopted by the Romulan Republic in the early 25th century.

History
The Dhelan-class was designed in the 23rd century in response to the Romulan Star Empire's conflicts with the United Federation of Planets, and was intended as a counter to the Constitution-class starship. A subsequent drop in tensions meant that the Dhelan would never advance beyond the early production stage, but elements of the design would go on to influence several later warbirds such as the Mogai-class.

In the early 25th century a number of unfinished Dhelan-class hulls were acquired and completed by Romulan Republic shipwrights and incorporated into the nascent Romulan Republican Navy. These vessels would serve in many engagements fought by the Republic in subsequent years.

Dhael
The Dhael variant was a much sleeker design than the standard Dhelan. It was developed with two wing options, one that included a top wing and the other without. The singularity inverter system was also added to this variant, allowing the warbird to absorb some of the power of incoming directed energy attacks to provide additional energy to the Dhael's systems.

Hathos
After seeing the success of the Dhelan-class, Reman engineers took its design and made it their own. The Hathos variant was an aggressive warbird that was both durable and agile. The warbird was also equipped with a railgun destabilizer that allowed the vessel to deliver a withering barrage of explosive blasts at nearby foes.
