Imperial Interdictor

The Immobilizer 418 cruiser (also known as the Interdictor Cruiser) is a vessel a six-hundred-meter-long cruiser that will appear in the Disney XD animated series Star Wars Rebels, used by the Galactic Empire. Built on the standard Vindicator-class heavy cruiser hull, these cruisers severed a special purpose in the Imperial Navy.

Equipped with gravity well projectors designed to pull ships from hyperspace and/or prevent them making the jump to lightspeed, the Immobilizer became a valuable addition to the Imperial Navy.

Description
Immobilizer 418 cruisers were designed by Sienar Fleet Systems, makers of the TIE Fighter. At first appearing to be a small Star Destroyer, the Immobilizer was recognizable because of the ship's four prominent globes; each globe housed a single gravity-well projector. Immobilizers also had twenty quad laser cannons for short-range combat against other capital ships. Imperial doctrine called for Immobilizers to be placed on a perimeter of a battle area. This gave Immobilizer captains a clear view of any battle so they could precisely target the placement of gravity wells to prevent rebel ships from escaping into hyperspace.

The biggest disadvantage that comes with the Immobilizers is that the gravity-well generators can take more than a minute to charge up, giving quick-thinking opponents a chance to jump to hyperspace before the gravity wells can be deployed again. The Immobilizer's hull has proven to be a reliable design; it is also favored by the Imperial bureaucracy because of its close resemblance to the Imperial Star Destroyer. Designers had used the hull, which can be fitted with a wide variety of weapons, for several heavy cruiser designs. The full and ship systems were easily convered for custom mission duties.
