Interdictor-class Heavy Cruiser

The Interdictor-class Heavy Cruiser, which was also called the Immobilizer 418 Cruiser, was the standard Imperial interdictor cruiser. It kept Rebel and pirate ships from fleeing into hyperspace, allowing them to be captured or destroyed.

It replaced the earlier CEC Detainer CC-2200 Interdictor Cruiser. In engagements where more durable options were needed there was the Interdictor-class Star Destroyer, but it was not built until sometime after the Interdictor-class was deployed.

These vessels cost more than an Imperial-class Star Destroyer, making them very expensive indeed.
