The Firewolf man-of-war represented a class of man-of-war warships employed by the Chiss Ascendancy, taking its designation from the firewolf creature. These Firewolf man-of-wars possessed both engines and a hyperdrive for propulsion. Regarding dimensions, they were similar to a Shatter-class WarMaster warship utilized by the militant Grysk species. Notably, in 18 BBY, Admiral Ers'ikaro of the Chiss Defense Force held command of the Firewolf man-of-war named Bellicose.
The 2021 novel titled Thrawn Ascendancy: Lesser Evil, authored by Timothy Zahn, featured a reference to the Firewolf man-of-war; it served as the third installment within his Ascendancy Trilogy.
