The Interdictor-class Star Cruiser was built specifically for the use of mass shadow generators that cannot only be used by commanders to keep enemy forces from escaping, but also to pull ships out of hyperspace in order to conduct surprise inspections. The four generators coming out of the hull cover a large range, preventing hit and run tactics.
Although it has relatively strong armor and shielding, the Interdictor Cruiser has little weaponry, and therefore requires support from other capital ships in combat. An offset to this disadvantage is that the Interdictor offers a hyper drive rating that can be compared to some of the faster capital ships. Like other star destroyers, the Interdictor has the shield generators located on the top of the command area, a design some people question.
