The Vengeance class of assault frigates are the workhorses of the Kushan fleet. Their four heavy turrets give excellent coverage, while dual forward-facing plasma bomb launchers give it the ability to devastate any capital ship in its path. Directly behind the massive engine housing is the only arc where the assault frigate is incapable of directing any sort of firepower. This, and the relatively slow tracking of the turret guns, means that despite its heavy offensive punch and deep armor plating, the assault frigate should not be deployed without an escort of fighters or multi-gun corvettes.

The Vengeance was named in remembrance of the Burning of Kharak, partially because the design is derived from captured Taiidan vessels that had directly participated in the atrocity.

After the development of the Firelance-class Ion Cannon Frigate, certain Kushan flag officers became enamored with the power of the new beam weapon, overlooking the power and flexibility of the Vengeance design. This blindness to the Firelance's limitations led to several stinging defeats that resulted in a strategic decision that Vengeance hulls would be constructed with the Firelance variants on a nearly one-for-one basis right up until the end of the Homeworld War.

Assault frigate crews are involved at almost every level of Kushan fleet operations, and as such have earned their namesake as a major participant in the campaign that brought down the Taiidan regime responsible for the near-genocide at Kharak.
