Covenant frigate
From Halopedia, the Halo wiki
Covenant Frigates seem to be the smallest and most common among the Covenant's space fleets equipped with three Pulse Lasers and at least one Plasma Torpedo turrent launcher. They appear at most Covenant-UNSC engagements. They are larger then a UNSC Frigate, but smaller then other UNSC ships. They have overall bubeus shape.
