The ship's armament consisted of 25 light turbolasers, 20 light quad turbolasers, 20 point-defense laser cannons, 20 light point-defense ion cannons, and 6 tractor beam projectors organized into 5 light turbolaser batteries, 5 light quad turbolaser batteries, 4 laser batteries, 4 ion cannon batteries and one capital - grade tractor beam battery.
The Vindicator was equipped with a Class 2 hyperdrive. It carried 400 troops and a crew of 2,551. Most Vindicators were specifically configured so that they could carry a full TIE starfighter wing and operate independently without the need for support ships. Other configurations could carry only two squadrons of starfighters.
It was intended for use in situations in which Imperial-class Star Destroyers were unavailable, and smaller ships were not powerful enough. The ship was manufactured by Sienar Fleet Systems.
They were to replace the Dreadnaught-class heavy cruiser as the Navy's standard multi-role cruiser.
The Immobilizer 418 cruiser was designed using the same basic hull as the Vindicator. In addition to manufacturing new Immobilizer 418s, the Empire converted a number of Vindicators into Interdictor cruisers. The Vindicator's hull was used again to build the Enforcer-class picket cruiser, a patrol ship used by the Pentastar Alignment.
The Vindicators were assigned as escorts or as lone hunters. Those postings were seen as prestigious by Imperial commanders.
A Vindicator-class heavy cruiser was present near the Death Star during X2 and Grey Squadron's mission there.
Some of these cruisers were eventually found in local fleets and large pirate squadrons, while an imperial Vindicator called Molator was captured by the Rebel Alliance.
