Vindicator-class heavy cruiser
Vindicator-class heavy cruiser were built on the same 600-meter frame as the Immobilizer 418 cruiser and Enforcer-class cruisers after Naval architects removed the massive power generators from an Interdictor cruiser and discovered that by re-arranging the vessels power grids, they could significantly beef up the ship's energy weapons, shields, and tractor beams. Even the engines experienced a bonus from this reconfiguration. The end result was a very fast and maneuverable vessel that was well armed for a ship its size.
An Vindicator-class picket cruiser can be created by removing the spheres from an Imperial Interdictor Cruiser from the original set).
