They can provide a significant challenge for a number of small ships due to excellent coverage from turret guns. Its size however makes it a big target. They have a low sensor signature, as well as the ability to cloak. In addition, they possess very high-end scanners which allow them to spot an enemy in time to evade detection. It is modestly well armed and maneuverable enough to dogfight standard fighters.
