Classes

Class	Image	Size	Details
A'uzr-pattern sword frigate		860.0 meters (2,821.5 ft)	Alternatively referred to as "command frigates", the A'uzr-pattern (UNSC three-letter classification: SCC-class sword frigate) is a class of warship used by the Covenant to command flotillas of smaller warships. They have much in common with the Ceudar-pattern heavy corvettes of the empire, and have been prominently used by the Swords of Sanghelios. They have a stacked hull, and are one of several design pattern variants under the SCC-class heading.
Ester-pattern armored frigate		1,000 meters (3,280 ft)	The Ester-pattern (UNSC three-letter classification: CAR-class armored frigate) is a class of warship used by the Covenant to command flotillas of smaller warships. They have much in common with the Ceudar-pattern heavy corvettes of the empire, and have been prominently used by the Swords of Sanghelios.
Unidentified class (Radiant Arrow)		550 meters (1,800 ft) (width) 110 meters (361 ft) (width)	This unidentified vessel is much smaller than the aforementioned frigate examples. It has a teardrop-shaped profile, with a long, tapering tail that curls up into an open hook. It has at least one hangar bay, which is mounted on the frigate's belly, which was built in an oblong shape that was twenty metres wide and thirty metres deep. It can accommodate at least five Elsedda-pattern Banshees. One such example, Radiant Arrow, served as part of the Fleet of Inexorable Obedience in 2526.
Unidentified class (Steadfast Strike)		Width less than 400 meters (1,300 ft) (the width of UNSC Phyllis Wheatley's salvage bay)	This unidentified vessel is shaped like a "long-necked disk", with a dovetail stern. It carried multiple weapon systems including secondary pulse laser turrets and a primary unknown weapon system. The frigate also carried a self-destruct system. One such vessel, Steadfast Strike, was part of the Flotilla of Unsung Piety.
