In the battle area, enemy Air Defence network comprising of early warning and weapon system radars would always pose imminent threat to friendly ac. To achieve mission goals by friendly airborne forces, suppression of enemy air defence is a mandatory factor. SEAD missions can be accomplished by using soft kill methods like jamming and spoofing of hostile radars by injecting the enemy radars with false targets using Air launched Loitering Decoys capable of carrying out EW missions. With option for integrating a warhead inside the decoy itself, the ALLDs should also be capable of DEAD missions. Therefore, the challenge is for development of Air Launched Loitering Decoys capable of carrying out SEAD and DEAD missions. The project includes design, development and certification of a fighter aircraft carried weapon system and its integration in aircraft systems for launch. Complete flight testing, safety clearances, life cycle support of the developed system are envisaged. The ALLD-EW will operate in autonomous mode after release from the aircarft based on Pre Flight Programs (PFMs) for navigation and EW operations. The ALLD-EW will pick-up enemy search and acquisition radar signals and manipulate them to put multiple false targets in the target Radars. False targets in search/ acquisition radars would further stimulate the enemy tracking and weapon system radars which would again be deceived with multiple false targets generated by the ALLDs resulting in Suppression of Enemy Air Defence (SEAD). System may have recovery capability using parachute. Post recovery, the ALLD may be capable of being made flight worthy at the ‘O’ level. In operational mode, the parachute recovery assembly may be replaced by a warhead thereby achieving the DEAD objective.
