The D'virin class was a type of incursion frigate fielded by the Romulan Star Navy during the 24th century. (Ship Recognition Manual, Volume 5: Starships of the Romulan Star Empire) The D'virin consisted of a teardrop-shaped central body with long, downward-slanting wing pylons on the side that connected to the warp nacelles. The D'virins lacked much in the way of crew amenities due to the space taken up by its large engines and other powerful systems.
