An Interdictor Cruiser is a type of starship in the fictional Star Wars universe. It was manufactured by Sienar Fleet Systems, and was one of the first vessels capable of pulling ships from hyperspace and preventing ships from entering hyperspace.
Interdictor Cruisers are about 690 meters long. Because of their triangular wedge shape, the vessels appear as smaller versions of the Imperial Star Destroyers. There are four large globe shaped structures present on the ship. These globe structures contain large scale gravity well generators . When the generators are powered up, they produce a gravity field that simulates a stellar mass. Because of the presence of the gravity field, hyperdrives are unable to function. Vessels in hyperspace will immediately drop to sublight, and no ship is able to enter hyperspace as long as the field is present.
The generators do require about a minute to power up after the Interdictor emerges from hyperspace. As a result, quick thinking pilots can escape into hyperspace before the field reaches full strength, although this escape window is much smaller for an entire fleet.
Compared to its larger cousin, the Imperial Star Destroyer, the Interdictor Cruiser is lightly armed. Because of this, in most situations the Interdictor accompanies a larger Star Destroyer. Imperial doctrine calls for the ship to remain out of the main combat situation, and maintain its presence at the perimiter.
The Interdictor Crusier was developed to limit the tactical advantage of Rebel Alliance starfighters that were hyperdrive equipped, as well as their hyperdrive equipped vehicles in general. Alliance tacticians developed a style of attack that was called "hit and hype" or "hit and fade" to take advantge of hyperdrive equipped starfighters. In this style of attack enemy ships would drop out of hyperspace, attack preselected targets, and re-enter hyperspace before they could be intercepted by Imperial fighters.
With the Interdictor Cruiser, Rebel ships would be trapped in an area. Even though Imperial fighters were weaker, they were more numerous, and could often overwhelm their Rebel opponents. Interdictor Cruisers were also used to pull freighters carrying contraband out of hyperspace and prevent them from escaping.
After the death of the Emperor at Endor, at least one Interdictor Cruiser defected to the New Republic. In the Star Wars computer game Mysteries of the Sith , part of the storyline indicates that a pirate group had seized one of these cruisers.
