Ha'feh class

The assault warbird was a class of starship in use by the Romulan Republic in the early 25th century. 

History
The Ha'feh-class was developed in tandem with the battlecruiser and  science vessel. 

Mirror universe
This class was also used by an unknown $𝜇$ state in the mirror universe. In 2409, around the time of the discovery of the Solanae Dyson sphere, the Romulan Republic captured a number of these vessels and incorporated them into the Romulan Republican Force. This version featured improved science capabilities over the prime universe iteration. ( [Season 8])

Technical data
The Ha'feh-class was smaller and less heavily defended than the Ha'apax and Ha'nom-classes, but in exchange had increased agility and firepower. It featured a standard Romulan cloaking device.
