Immobilizer 418 Interdictor-class Heavy Cruiser
The Immobilizer 418 Interdictor‑class heavy cruiser is a capital starship used to pull ships out of hyperspace and prevent them from reentering, trapping them in realspace and keeping them from escaping. The Immobilizer 418 uses four massive gravity well generators that produce a gravity shadow un hyperspace (similar to that projected by a planet or a star) that makes hyperspace travel through that area impossible. When an Immobilizer 418 has its gravity well projectors fired up, any ships traveling through hyperspace in the vicinity immediately revert to realspace, and no ship within a hyperspace interdiction area can make the jump to lightspeed until the gravity well generators are shut down.
The Immobilizer 418 was development in response to the hit-and-run tactics of the Rebel Alliance. The success of the Immobilizer 418 once again gave the Empire an advantage over Rebel tacticians, though fortunately for the Alliance, only a relatively small number of Interdictor‑class heavy cruisers were converted for use during the Galactic Civil War. However, the ships were so successful that some Star Destroyers were retrofitted with gravity well projectors in order to provide a more powerful platform for interdiction technology.
Capabilities
The Immobilizer 418 is typically accompanied by a contingent of more heavily armed vessels, not only to lie in ambush but also to protect the Interdictor‑class heavy cruiser from the ships they are trapping. Pulling a Rebel fleet out of hyperspace typically makes the Immobilizer 418 the primary target of the trapped fleet, and as a result the ship needs protection in order to keep from being destroyed.
Once the Immobilizer 418 has pulled the targets from hyperspace, the ship’s crew must keep the gravity wells focused on the trapped fleet otherwise their prey will escape into hyperspace simply by out running the Immobilizer and its fellow ships. Directing a gravity well is no simple matter, requiring the same kind of precision and expertise as is required to operate a tractor beam, and the Immobilizer 418’s crew is specially trained to maintain gravity wells in the heat of combat.
Tactical Fire: The Vindicator‑class heavy cruiser and the Immobilizer 418 were both designed to keep enemy ships from fleeing, by the use of either firepower or gravity wells. As a standard action, an Immobilizer 418 or Vindicator‑class heavy cruiser can forgo all attacks to provide tactical fire to all squares in a 2-square radius around itself. All enemy starships moving into that area must succeed on a DC 20 Pilot check or stop moving for the remainder of the round. Once a ship is within this area, no further Pilot checks are required, though if a ship leaves this area and then moves into it again, a new Pilot check must be attempted.
