D'Vorix class starships were a design manufactured by the Romulan Star Empire through the 2290s.
D'Vorix class ships consist of a bulbous command module at the end of a long narrow neck with wide nacelle mounts.
The class proved an effective warship and was used in the conquering and occupation of many planets, including Cort.
After the 2290s, no new D'Vorix class ships were manufactured but existing ones stayed in commision as late as 2311, when three escorted the flagship Tomed to an invasion of Koltaari.
This class appears to be an improvement on the D7 class cruiser obtained by the Romulans through a brief treaty with the Klingons as it uses a similar hull design.
