Men'los class

The Men'los class was a type of warbird that saw service with the Romulan Star Navy during the 24th century. The Men'los entered service in 2322 and was similar in design to the Argus-class, but larger with a more "rounded" hull. By the 2340s the Star Navy began to actively look for a replacement, eventually culminating in the D'deridex-class. (Ship Recognition Manual, Volume 5: Starships of the Romulan Star Empire)
