Radar Warning Receiver (RWR) is being co-produced in collaboration with M/s CEIEC China and is designed to provide the pilot with real time and unambiguous threat warning over 360 degrees thus reducing vulnerability of the combat aircraft to radar associated weapons. Currently two different models of RWR are available i.e. BM/KJ-8602 RWR and BM/KJ-8602A RWR. PAC also provides the life cycle maintenance of these two RWR models to PAF.
