The Australian Government has signed two new agreements to expand its partnership with the US for the Next Generation Jammer (NGJ) system development.

The NGJ is a programme that will replace older ALQ-99 tactical jamming system pods on the EA-18G Growler aircraft.

The advanced electronic attack system has the capability to deny, disrupt, and degrade enemy’s technology, including radars, air defence systems, and communication tools.

During operations, the system supports electromagnetic spectrum dominance, provides pilots of Growler aircraft an edge, and counters low frequency adversary systems.

The NGJ-Low Band enhances the fourth and fifth-generation platforms’ survivability and lethality.

Australian Defence Minister Linda Reynolds said: “Australia entered an initial agreement in October 2017 to work with the US Navy to develop the NGJ, which will supersede the current system. We’ve now signed two new agreements to expand this partnership.

“The first includes production, sustainment and follow-on development of the ALQ-249(V)1 NGJ -Mid Band, which supports the introduction of advanced electronic jamming technology and will ensure Australia’s Growler aircraft retain commonality with their US counterparts.

“The second agreement enables the development of the next variant, the NGJ-Low Band. These systems will augment, and ultimately replace, most legacy ALQ-99 Tactical Jamming Systems currently used on the Growler.”

In a separate development, more than 1,000 US Marines personnel have joined the annual Marine Rotational Force – Darwin (MRF-D), following the completion of a quarantine period in the Northern Territory.

The US Marines are currently undertaking a modified training programme at various defence training facilities in Mount Bundey and Kangaroo Flats.
