Much quicker that subspace movements, the Thrawn pincer allowed reinforcements to be swiftly deployed on the battlefield and afforded a considerable element of surprise. Other vessels (typically Star Destroyers) would be contacted, and would blindly execute a micro-hyperspace jump straight into the Interdictor's gravity wells, yanking them out of hyperspace and near an enemy vessel. The 'Thrawn pincer' positioned the Interdictor's gravity wells along certain vectors. Thrawn was especially famous in connection with Interdictors for developing and refining a tactic that would be named after him. In fleet operations, they were usually found on the periphery of the battle they were affecting, dependant on better equipped capital ships and starfighters to deliver the necessary damage.Дuring the Galactic Civil War, only a few hundred Interdictors were built, as they were more expensive than a regular Star Destroyer of comparable size, were less effective in battle, and their primary use was strategic.ДЇollowing the Battle of Endor, Imperial warlords, such as Grand Admiral Thrawn, realized the importance of the ship and carefully deployed them. Interdictors were also poorly protected and armed for their size, unable to successfully match up with vessels of equal size.

When enemy ships were able to inflict significant damage to the Interdictor, the captain was forced to choose between entrapment of the enemy and his shipвЂ™s own protection. Foremost was that the gravity well generators took several minutes to 'warm up' (though the duration was rarely enough for an entire fleet to escape), and were an extremely large drain on the shipвЂ™s resources. The Immobiliser class had several weaknesses. Freighters pulled out of hyperspace by an Interdictor would be in a position to have their cargo inspected. It was only when they tried to escape into hyperspace that they realized it was an Interdictor.ДЄ secondary duty of this class was to patrol trade routes. Rebel pilots often mistook it for a miniature Star Destroyer when it was accompanied by Star Destroyers. Either path would result in significant damage to the Alliance forces. Starfighter and capital ship support were then be used to eliminate the attackers, whose only options were to try to run for the edge of the interdiction field, or to attack the Interdictor and hope to inflict enough damage to disable the cruiserвЂ™s influence. This was primarily to counter Alliance 'hit and hype' tactics, where a small group of starfighters or light starships would emerge from hyperspace, attack preselected targets, and re-enter hyperspace before sufficient force could be brought to bear on the raiders.ДЄn Interdictor at the site of attack, or able to access the area with a brief hyperspace jump, would be tasked to power up its gravity well generators in an attempt to prevent the escape of the raiding party. Interdictor cruisers were initially developed as a counter to the Rebel AllianceвЂ™s hyperdrive-equipped starfighters in particular, and hyperdrive equipped vessels in general. This can be used for two purposes, to prevent vessels entering hyperspace, and to force craft currently in hyperspace to revert to sublight speeds. These generators, when engaged, simulate the presence of a medium-sized planetary body and in particular the effect such a body would have on hyperspace travel.

Built upon the Vindicator-class Heavy Cruiser, it is a special-purpose vessel, the first warship class of the Imperial Starfleet to incorporate gravity well generators as standard equipment. The Immobiliser-418 -class Interdictor Cruiser is a starship from the fictional Star Wars universe. 4.4 Sovereign-class Super Star Destroyer.4 Known examples of Interdictor Cruisers.
