Raytheon’s NGJ-MB Takes to the Skies for Growler Flight Testing
The Next Generation Jammer Mid-Band (NGJ-MB), built by Raytheon Intelligence & Space (RI&S), a Raytheon Technologies business, recently flew on an EA-18G Growler – its first flight test on the aircraft. The U.S. Navy’s NGJ-MB is an advanced electronic attack system that denies, disrupts and degrades enemy technology, including communication tools and air-defence systems.
The first flight took place on August 7, at the Naval Air Station Patuxent River, Maryland, U.S. meeting all objectives. Future mission systems flight testing will demonstrate weapons system control, power generation, and electromagnetic compatibility between jammer and aircraft, as well as the performance of NGJ-MB’s high-capacity digital waveform generation and active electronically scanned arrays in flight against a variety of targets. Data from these flight tests on the Growler will inform Milestone C – the Navy’s decision to start NGJ-MB production.
The flight follows more than 600 hours of ground testing of Engineering Development Model (EDM) pods. At the Naval Air Stations Patuxent River and at Point Mugu, California, EDM pods underwent anechoic chamber testing to measure the jammer’s radio frequency power and beam-steering capabilities.
To date, RI&S has delivered 10 EDM pods: six mission systems pods and four aeromechanical pods. A total of 28 pods will be delivered under the EMD contract.
