Next Generation Jammer

Raytheon’s Next Generation Jammer solution was selected by the U.S. Navy in 2013 to replace the legacy ALQ-99 systems used on the EA-18G airborne electronic attack aircraft. In 2016, the U.S. Navy awarded Raytheon a $1B Next Generation Jammer Engineering and Manufacturing Development contract.

Raytheon’s NGJ solution will provide innovative airborne electronic attack and jamming capabilities.

Increasingly complex threats require airborne electronic attack to be more sophisticated than ever, providing greater precision, power, reactive speed and directivity. Raytheon’s NGJ will integrate the most advanced electronic attack technology into the EA-18G to ensure superior mission performance.

Built with a combination of high-powered, agile beam-jamming techniques, and cutting-edge solid-state electronics, our NGJ systems will meet the U.S. Navy’s current mission needs while providing a cost-effective open systems architecture for future upgrades. The proven expertise we bring to the NGJ effort will yield a low-risk, highly reliable baseline solution with opportunities for growth on additional manned and unmanned platforms.

Building on a strong history of creating and integrating advanced solutions for the warfighter, Raytheon’s NGJ effort will produce the most reliable, dependable and affordable system to deny, degrade and disrupt threats while protecting U.S. and coalition forces. Source raytheon.com

Electronic warfare: Navy advances next-generation jammer

The Navy’s Next-Generation Jammer, to be ready by 2021, is designed to jam multiple radars at the same time and defeat future high-tech enemy air defenses.

The Navy is engineering a new, more powerful, high-tech electronic warfare jamming technology designed to allow strike aircraft to destroy enemy targets without being detected by modern surface-to-air missile defenses.

“The whole idea is to get the enemy air defense systems from seeing the strike package. It does not matter what type of aircraft we are protecting. Our mission is to suppress enemy air defenses and allow the mission to continue. This is not just designed to allow the aircraft to survive but also allow it to continue the mission – deliver ordnance and return home,” Cmdr. Ernest Winston, Electronic Attack Requirements Officer, said in an interview.

The Next-Generation Jammer consists of two 15-foot long PODs beneath the EA-18G Growler aircraft designed to emit radar-jamming electronic signals; one jammer goes on each side of the aircraft.  Radar technology sends an electromagnetic ping forward, bouncing it off objects before analyzing the return signal to determine a target’s location, size, shape and speed…etc.  However, if the electromagnetic signal is interfered with, thwarted or “jammed” in some way, the system is then unable to detect the objects, or target, in the same way.

“It is able to jam multiple frequencies at the same time — more quickly and more efficiently,” he said.

The emerging system uses a high-powered radar technology called Active Electronic Scanned Array, or AESA.

“It will be the only AESA-based carrier offensive electronic attack jamming pod it DoD. What it is really going to bring to the fleet is increased power, increased flexibility and more capacity to jam more radars at one time,” Winston added.

The NGJ, slated to be operational by 2021, is intended to replace the existing ALQ 99 electronic warfare jammer currently on Navy Growler aircraft.

The new jammer is designed to interfere with ground-and-air based threats such as enemy fighter jets trying to get a missile “lock” on a target.

One of the drawbacks to ALQ 99 is that it was initially designed 40-years ago and is challenged to keep up with modern threats and digital threats with phased array radars, increased power, increased processing and more advanced wave forms, Winston explained.

The Next-Generation Jammer is being engineered with what’s called “open architecture,” meaning it is built with open computing software and hardware standards such that it can quickly integrate new technologies as threats emerge.

For example, threat libraries or data-bases incorporated into a radar warning receiver can inform pilots of specific threats such as enemy fighter aircraft or air defenses. If new adversary aircraft become operational, the system can be upgraded to incorporate that information.

“We use threat libraries in our receivers as well as our jammers to be able to jam the new threat radars. As new threats emerge, we will be able to devise new jamming techniques. Those are programmable through the mission planning system through the mission planning system of the EA-18G Growler,” Winston explained.

While radar warning receivers are purely defensive technologies, the NGJ is configured with offensive jamming capabilities in support of strike aircraft such as an F/A-18 Super Hornet or F-35 Joint Strike Fighter.

The jammer is intended to preemptively jam enemy radars and protect aircraft by preventing air defenses from engaging.

“With surface-to-air missile systems, we want to deny that track an engagement opportunity. We try to work with the aircraft to jam enemy radar signals,” Winston added.

The NGJ could be particularly helpful when it comes to protecting fighter aircraft and stealth platforms like the B-2 bomber, now-in-development Long Range Strike-Bomber and the F-35 multi-role stealth fighter. The technology is designed to block, jam, thwart or “blind” enemy radar systems such as ground-based integrated air defenses – so as to allow attack aircraft to enter a target area, conduct strikes and then safely exit.

This is useful in today’s modern environment because radar-evading stealth configurations, by themselves, are no longer as dominant or effective against current and emerging air-defense technologies.

Today’s modern air defenses, such as the Russian-made S-300 and multi-function S-400 surface-to-air missiles, will increasingly be able to detect stealth aircraft at longer distances and on a wider range of frequencies. Today’s most cutting edge systems, and those being engineered for the future, use much faster computer processors, use more digital technology and network more to one another.

“Multi-function radars become much more difficult because you have a single radar source that is doing almost everything with phased array capability. However, with the increased power of the next-generation jammer we can go after those,” Winston said.

“It is a constant cat and mouse game between the shooter and the strike aircraft. We develop stealth and they develop counter-stealth technologies. We then counter it with increased jamming capabilities.”

The NGJ is engineered to jam and defeat both surveillance radar technology which can alert defenses that an enemy aircraft is in the area as well as higher-frequency “engagement” radar which allow air defenses to target, track and destroy attacking aircraft.

“The target engagement radar or control radar has a very narrow scope, so enemy defenses are trying to search the sky. We are making enemies search the sky looking through a soda straw. When the only aperture of the world is through a soda straw, we can force them into a very narrow scope so they will never see aircraft going in to deliver ordnance,” Winston said.

Winston would not elaborate on whether the NGJ’s offensive strike capabilities would allow it to offensively attack enemy radio communications, antennas or other kinds of electronic signals.

“It can jam anything that emits or receives and RF frequency in the frequency range of NGJ — it could jam anything that is RF capable,” he explained.

The U.S. Navy recently awarded Raytheon Company a $1 billion sole source contract for Engineering and Manufacturing Development (EMD) for Increment 1 of the Next Generation Jammer (NGJ), the advanced electronic attack technology that combines high-powered, agile, beam-jamming techniques with cutting-edge, solid-state electronics,” a Raytheon statement said.

Raytheon will deliver 15 Engineering Development Model pods for mission systems testing and qualification, and 14 aeromechanical pods for airworthiness certification.

The NGJ contract also covers designing and delivering simulators and prime hardware to government labs and support for flight testing and government system integration, Raytheon officials said.

Overall, the Navy plans to buy as many as 135 sets of NGJs for the Growler. At the same time, Winston did say it is possible that the NGJ will be integrated onto other aircraft in the future.

“This is a significant milestone for electronic warfare,” said Rick Yuse, president of Raytheon Space and Airborne Systems. “NGJ is a smart pod that provides today’s most advanced electronic attack technology, one that can easily be adapted to changing threat environments. That level of sophistication provides our warfighters with the technological advantage required to successfully prosecute their mission and return home safely.”
