The United States Navy and Australia will work jointly on the new Raytheon AN/ALQ-249 Next Generation Jammer that is currently being developed for the Boeing EA-18G Growler airborne electronic attack aircraft. Both the U.S. Navy and the Royal Australian Air Force fly the Growler, which is a derivative of the Boeing F/A-18F Super Hornet strike fighter.
According to the U.S. Naval Air Systems Command (NAVAIR), the Airborne Electronic Attack Systems and EA-6B Program Office (PMA-234) and Royal Australian Air Force (RAAF) signed a memorandum of understanding (MOU) on Oct. 18 to jointly develop the AN/ALQ-249 Next Generation Jammer Mid-band (NGJ-MB) from here on in.
