The Victory II-class Star Destroyer Aggressor is a line ship in the Aggressor Strike Force, housing the Avenger Elite Squadron. It was the original home for the ASF (when it was the Aggressor Wing) before the ASF received its compliment of ISDIIs.

It is currently active housing the office of the Combat Operations Officer, under the command of Admiral Silwar Naiilo.
