The Unasha class was a type of battle cruiser fielded by the Othan Empire during the 24th century. (Ship Recognition Manual, Volume 5: Starships of the Romulan Star Empire)

The Usasha consisted of a wedge shaped main hull that was attached to a second dome like command hull on its dorsal aft. From the aft end of the main hull were two pylons that held the ship's warp nacelles.

These ships were purely warships and were armed with numerous disruptor cannons. These ships lacked transporter and replicator technology due to the Othans having not developed it at the time.
