The DER Projector, more formally known as the dedicated energy receptor projector, was an integral part of the 4x-Phantom Short-Range Sensor Jammer. This jammer was employed on the RZ-1 A-wing interceptor that was built by Miradyne Limited. Its function was to soak up and then prevent the reception of long-range sensor signals and communications sent out by opposing vessels. This action effectively made the starfighter undetectable by the majority of hostile scanning equipment, targeting computers, and incoming missiles.
