Raytheon has completed the first power generation flight test of the Next Generation Jammer Mid-Band (NGJ-MB). The US Navy will use the test data to inform the airworthiness authorisation decision to fly NGJ-MB on the EA-18G Growler in the spring of 2020 – with follow-on potential for Australia’s fleet of Growlers.
Raytheon conducted the three flight tests onboard a Calspan commercial jet to assess the jammer’s prime power generation system, known as the ram air turbine generator, at Niagara Falls Airport in New York. The generator scoops air from the airstream, turns a turbine, and creates electricity that enables NGJ-MB to jam enemy radars and communications.
Ernest Winston, senior manager for Electronic Warfare Systems, said, “This is the first time the pod generated its own power outside of a lab. Future tests will verify the power is sufficient to enable NGJ-MB to significantly enhance range, attack multiple targets simultaneously, and perform advanced jamming.”
Raytheon’s NGJ-MB architecture and design include the ability to operate at a significantly enhanced range, attack multiple targets simultaneously, and advanced jamming techniques. The technology can also be scaled to other missions and platforms.
Initially purchased alongside the more traditional Super Hornet variants to supplement Australia’s ageing fleet of classic Hornets and the diminished strike capability following the retirement of the F-111s, prior to the full integration of the Air Force’s 72 planned F-35s, IOC is expected to be delivered to the RAAF in the coming months.
Raytheon’s NGJ-MB ram air turbine generator is designed to give the Growler more power than it has ever had before to jam at unprecedented levels. Its open architecture and design allow the technology to be scaled to other missions and platforms.
Australia’s Growlers were part of a larger US Navy buy of 44 Super Hornets and Growlers in July 2014, with the first Australian EA-18G making its first flight in July 2015. All 12 of Australia’s Growlers were formally welcomed to their home base at RAAF Amberley in 2017, providing air crews and pilots the opportunity to build familiarity and an understanding of the aircraft and its unique capabilities.
Based on F-18E/F Super Hornet variant of the wildly successful Boeing Hornet, the EA-18G Growler has proven itself to be an invaluable asset to the US when deployed overseas. As the only nation besides the US to fly the Growler, Australia has developed unique training procedures in conjunction with US Navy partners to fully utilise the capabilities of the aircraft.
It is now expected that the Growlers of No. 6 Squadron RAAF will be capable of providing limited, force-level electronic warfare. This means that until final operating capability (FOC) is achieved, the aircraft will be largely limited to peacetime operations or responding to regional contingencies as needed.
The Growler incorporates a number of advancements over the traditional Super Hornet, including:

- ALQ radio-frequency jamming pods, which enable it to jam enemy systems.
FOC for Australia’s Growlers is expected in 2022. Reaching FOC will require additional testing and broader integration with key ADF assets, particularly the Navy’s new Air Warfare Destroyers, Air Force’s E-7 Wedgetail AEWC aircraft and later F-35s and key ground assets of the Army to ensure that the ADF is developed into a full-spectrum, integrated force.
