By jamming enemy radar, the EA-18G Growler helps aircrews reach their target without being detected. The Growler is an elite electronic attack aircraft that helps save lives. The Growler’s flight performance is similar to that of the F/A-18E/F. This attribute enables the Growler to perform escort jamming as well as the traditional standoff jamming mission (Radar jamming and deception). Growlers will be able to accompany F/A-18s during all phases of an attack mission. In order to give the Growler more stable flight for the electronic warfare mission, Boeing changed the leading edge fairings and wing fold hinge fairings, and added wing fences and aileron “tripper strips”.
The Growler has more than 90% in common with the standard Super Hornet, sharing airframe, Raytheon AN/APG-79 AESA radar and weapon systems such as the AN/AYK-22 stores management system. Most of the dedicated airborne electronic attack equipment is mounted in the space that used to house the internal 20 mm cannon and on the wingtips. Nine weapons stations remain free to provide for additional weapons or jamming pods. The added electronics include AN/ALQ-218 wideband receivers on the wingtips, and ALQ-99 high and low-band tactical jamming pods. The ALQ-218 combined with the ALQ-99 form a full spectrum electronic warfare suite that is able to provide detection and jamming against all known surface-to-air threats. However the current pods may be inadequate against emerging threats.
The EA-18G can be fitted with up to five ALQ-99 jamming pods and will typically add two AIM-120 AMRAAM or AGM-88 HARM missiles. The EA-18G will also use the INCANS Interference Cancellation system that will allow voice communication while jamming enemy communications, a capability not available on the EA-6B. In addition to the radar warning and jamming equipment the Growler possesses a communications receiver and jamming system that will provide suppression and electronic attack against airborne communication threats.
