Australia, who is acquiring 12 EA-18G Growler aircraft, wants to be a part of US Navy's AN/ALQ-249 Next Generation Jammer-Medium Band (NGJ-MB) programme which has been initiated to replace AN/ALQ-99 tactical jamming system on USN's EA-18G Growlers.

The Naval Air Systems Command (NAVAIR) confirmed on 5 July that Australian Department of Defence is in negotiations with NAVAIR's Airborne Electronic Attack Systems and EA-6B Program Office (PMA-234) and the Navy International Programs Office (Navy IPO) regarding their intentions to join the programme, which will provide the Growlers with enhanced airborne electronic attack (EA) capabilities to disrupt and degrade enemy air defence and ground communication systems. 

The AN/ALQ-249 Next Generation Jammer-Medium Band (NGJ-MB) programme will utilize high power active electronically scanned arrays based on gallium nitride technology and feature some amendments in terms of software-based digital architecture.
