This class is the most common warship in both fleets. The UNSC light warships include the corvette, UNSC frigate/light frigate, stealth cruiser, and UNSC destroyer, while the Covenant's light warships include the Covenant frigate, the SDV-class heavy corvette and the Covenant destroyer. Also, several Covenant cruisers (CRS-class light cruiser, Covenant cruiser, and CAR-class frigate) are very small compared to other Covenant ships, but they're not classified as light warships.
