The Dhelan-class warbird was a class of starship designed by the Romulan Star Empire in the late 23rd century. By the 25th century they had been adopted by the Romulan Republic. (STO video game: Legacy of Romulus)
History[]
The Dhelan-class was designed in the 23rd century in response to the Romulan Star Empire's conflicts with the Federation, and was intended as a counter to the Constitution-class starship. A subsequent drop in tensions meant that the ship 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. (STO website: Dev Blogs)
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 Force. These vessels would serve in many engagements fought by the RRF in subsequent years. (ST video game: Star Trek Online)
In January 2409 the Dhelan-class RRW D'serek, captained by Commander Temer, led a flotilla of Republic ships to Virinat to help drive off attacking Tal Shiar and Elachi under Colonel Hakeev. (STO mission: "Flight from Virinat")
Another Dhelan-class, RRW Hyperian under Makus, arrived in the Virinat system to investigate information received from the Tal Shiar that the colony had been manufacturing weapons. This proved to be a trick intended to get him and the Virinat Survivor to kill each other, and after the two captains figured this out they worked together to defeat another Tal Shiar force. (STO mission: "Memory Lane")
Several Dhelan-class vessels fought alongside the RRW Deihu in the Azha system against yet another Tal Shiar force, defending the Virinat Survivor and the IRW Aethra under Charva. (STO mission: "Tradecraft")
More Dhelan-class ships joined the Virinat Survivor in destroying Hakeev's flagship IRW Khnial in deep space, and later helped fend off a major Elachi attack on New Romulus. (STO missions: "Mind Game", "Devil's Choice")
A number of these ships were captured by the Tholian Assembly and taken to bases in the Azure Nebula. They were successfully retrieved by allied forces. (STO mission: "Azure Nebula Rescue")
A Dhelan-class vessel also assisted a Klingon Defense Force vessel in defeating the IRW Solius in the Vor system. (STO mission: "Friend or Foe")
Later that year a Dhelan-class and another vessel responded to a distress signal sent by the IRW Areinnye in the Burgus system and helped destroy a Borg force. (STO mission: "Where Angels Fear to Tread")
Mirror universe[]

The Dhelan-class was also in use by an unknown Romulan faction in the mirror universe. In late 2409, around the time of the battle for the Jenolan Dyson Sphere, the prime universe Romulan Republic acquired several of these vessels and incorporated them into the RRF. The mirror universe version proved to have expanded scientific capabilities compared to the Republic's version. (STO website: Dev Blogs)
Specifications[]
Technical data[]
The Dhelan-class was larger and more heavily armed and armored than the earlier T'liss-class warbird and featured a standard Romulan cloaking device.
The refits performed by the Romulan Republic included a probe capable of attaching to an enemy vessel and siphoning off weapons power. It could also be made to self-destruct with a wide area of effect. The Republic also developed a variant design, the Dhael-class. (STO video game: Legacy of Romulus)
Class variations[]
The hull of the Dhelan-class warbird allowed its commanding officer to choose from different designs of livery, which could be modified further at allied hubs. These options were designated Reman Type 1-2, Romulan Type 1-4, Romulan Type 2 Brown, Veteran, Mirror, Upgrade and two versions of Fleet. (STO - From the Ashes mission: "Explore the Flotilla")
Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion. (STO missions: "Coliseum", "Cold Storage", "Boldly They Rode")

Legacy of Romulus Dev Blog #3 states that the Dhelan-class was used heavily by the RSE through the 24th century, but this appears to have been retconned as the in-game description and another blog entry state that the design began production but was never completed.
The Dhelan-class also appears on the NPC starship lists for the Remans, although it is not guaranteed to appear.
