These ships had the ability to cloak using technology Zann bought from the black market. However, due to a side effect of this addition, the ships possessed no shields. To make up for it, they were equipped with extremely thick armor for protection. Because of this extra protection, it dramatically affected its speed, making it very slow.
Behind The ScenesEdit
As with the Aggressor-class Star Destroyer, the Vengeance-class shares little with Imperial ship designs, bearing much more similarity with the Zann Consortium ships.
