Cedaur-pattern heavy corvette (EXverse)

The SDV-class heavy corvette is a escort ship previous in service with the Covenant fleet. Designed to escort capital ships and deploy ground and air assets, it was also capable to operate independently, even if it wasn't fit for direct engagement against other ships.
Conceived during the Twentieth Age of Discovery, as soon as it was commissioned it became the standard escort for capital ships, thanks to their agility and good firepower; for these reasons, during the Human-Covenant War they were rarely deployed on their own, but they proved to match a human frigate and win a bit easily.
After the collapse of the Covenant empire, many SDVs fell into rebel and Covenant remnants hands, threatening humanity once again.
