Mogai class

The 'Mogoai-class was a type of Romulan warbird in service in the late 2370s and early 2380s. The IRW Valdore, flagship of Commander Donatra of the Romulan Imperial Fleet, was Mogoai-class. (Taking Wing.)

Mogoai-class warbirds later came to make up part of the fleet of the Imperial Romulan State after Donatra declared its existence and herself to be its empress. (Articles of the Federation.)

The class name is from Taking Wing. Canonically, the class is often called "Valdore-type."
