The Imperial Frigate is a line of frigates used by the Terran Empire's Imperial Starfleet. It is identical to the Federation Frigate except for a few cosmetic differences. Although a basic ship in terms of weaponry, design and speed, the vessel is quite versatile in its role, and encountered often wherever the Terran Empire crosses into the prime universe.
Like its prime counterpart, there are three subclasses of frigates: Miranda-class, Centaur-class, and ShiKahr-class. Besides their different look their abilities are the same.
- Emergency Power to Engines II
- Emergency Power to Shields I
- Extend Shields
- Cloak (this ability is only used in cutscenes, not during actual gameplay)
