The Next Generation Jammer is a program to develop an airborne electronic warfare system, as a replacement for the AN/ALQ-99 found on the EA-18G military aircraft. It reached Initial Operating Capability in 2021.
The AN/ALQ-99 is currently mounted on the EA-18G Growler aircraft of the U.S. Navy and the Royal Australian Air Force, as well as the now-retired EA-6B Prowler aircraft belonging to the U.S. Marine Corps.
In the primary role of suppression of air defenses, these aircraft are to provide modified escort jamming from outside the range of known surface to air missiles. [1]
The poor reliability of the ALQ-99 and frequent failures of the Built In Test (BIT) have caused crew to fly missions with undetected faults. The ALQ-99 also interferes with the aircraft's AESA radar, reduces the top speed of the aircraft and imposes a high workload on the two man crew. [2]
The United States Marine Corps is considering replacing their Northrop Grumman EA-6B Prowler electronic attack aircraft with F-35s that have stealthy jammer pods attached. [3] In September 2008, the United States Navy outlined the basic requirements of the NGJ and stated that the design must be modular and open. [4] The Navy selected four companies to submit designs for the Next Generation Jammer. [5] The NGJ will have cyber attack capabilities where the AESA radar is used to insert tailored data streams into remote systems. [6] [7]
The ITT-Boeing design for the NGJ includes six AESA arrays for all around coverage. [8] [9] The team was awarded a $42 million contract to develop their design based on ITT's experience with broadband electronically steerable antenna arrays. [10] At the same time contracts were also awarded to Raytheon, Northrop Grumman and BAE Systems. [11]
After having existing jamming platforms thinly stretched over three wars during Operation Odyssey Dawn, the Navy accelerated the NGJ program and anticipated a vendor selection in 2013 instead of 2015 as previously planned. [12]
All contractors bidding for the program included Active Electronically Scanned Array technology in their plans. [13]
The Office of Naval Research has started a Next-Generation Airborne Electronic Attack (NGAEA) project to develop technologies for the NGJ. [14]
The system was expected to be fielded (on the Growler) by 2020, [15] but budget cuts pushed IOC to 2021, and now to 2022 for the Mid Band pod. [16] [17] Tom Burbage of Lockheed Martin has said that the NGJ would be carried by his company's F-35 in 2022 or 2023. [18] Marine Corps Commandant Gen. James Amos has said that unlike previous generations of aircraft, the base EW systems in the standard F-35 will allow it to just attach the pods and perform the mission, without having to make a special electronic warfare version of the F-35.

In July 2013 it was announced by Navair that the $279 million Technical Development (TD) phase of the contract had been awarded to Raytheon Space and Airborne Systems. [20] [21] [22] On 26 July 2013, the Navy issued Raytheon a stop-work order, following a formal protest of the contract by BAE Systems. [23] In December 2013, the Government Accountability Office upheld the protest, claiming they found that the Navy used improper procedures to select Raytheon. The Navy examined the issue and continued with Raytheon. [24]
In 2013 Boeing invested their own funds in a series of upgrades that they believe will be needed for the Growler to field the NGJ. [25]
After a successful System Readiness Review in June 2014, Raytheon expects to move forward with flight testing in September 2014 and an IOC of late 2020. The test was flown in November 2014. [26] The pod operates independently of the aircraft's systems, automatically responding to identified threats. One unique aspect of the NGJ is that its AESA array combines EW, coms, radar, and signals intelligence. AESA is known to perform EW and radar, but also handling SIGINT and serving as a communications array are new capabilities. Other than dedicated EW aircraft, the pods can be installed on other platforms like the UCLASS with little modification. [27]
The Royal Australian Air Force is contributing $250 million towards the NGJ program, and is directly participating in its development. [28]
The first flight test of the mid-band (MB) version of the pod took place in August 2020 aboard an EA-18G out of Naval Air Station Patuxent River in Maryland. This flight was intended to prove that the pod could be safely flown aboard the EA-18G. Initial Operating Capability is on the MB pod in FY 2022, with a Capability Block 1 contract awarded in the fall of 2020. The mid-band and then the low-band pods will supplement the legacy jamming system on the Growlers until the high-band, the last of the three increments, is fielded and the legacy system can be safely retired.

The Northrop GrummanEA-6B Prowler is a twin-engine, four-seat, mid-wing electronic-warfare aircraft derived from the A-6 Intruder airframe. The EA-6A was the initial electronic warfare version of the A-6 used by the United States Marine Corps and United States Navy. Development on the more advanced EA-6B began in 1966. An EA-6B aircrew consisted of one pilot and three Electronic Countermeasures Officers, though it was not uncommon for only two ECMOs to be used on missions. It was capable of carrying and firing anti-radiation missiles (ARMs), such as the AGM-88 HARM.
The McDonnell DouglasF-15E Strike Eagle is an American all-weather multirole strike fighter derived from the McDonnell Douglas F-15 Eagle. The F-15E was designed in the 1980s for long-range, high-speed interdiction without relying on escort or electronic-warfare aircraft. United States Air Force (USAF) F-15E Strike Eagles can be generally distinguished from other US Eagle variants by darker aircraft camouflage, conformal fuel tanks (CFTs) mounted along the engine intake ramps and a tandem-seat cockpit.
The Northrop Grumman E-10 MC2A was planned as a multi-role military aircraft to replace the Boeing 707-based E-3 Sentry and E-8 Joint STARS, the Boeing 747-based E-4B, and the RC-135 Rivet Joint aircraft in US military service. The E-10 was based on the Boeing 767-400ER commercial airplane.
The Boeing EA-18G Growler is an American carrier-based electronic warfare aircraft, a specialized version of the two-seat F/A-18F Super Hornet. The EA-18G replaced the Northrop Grumman EA-6B Prowlers in service with the United States Navy. The Growler's electronic warfare capability is primarily provided by Northrop Grumman. The EA-18G began production in 2007 and entered operational service with the US Navy in late 2009. Australia has also purchased thirteen EA-18Gs, which entered service with the Royal Australian Air Force in 2017.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
The Boeing F/A-18E and F/A-18F Super Hornet are twin-engine, carrier-capable, multirole fighter aircraft variants derived from the McDonnell Douglas F/A-18 Hornet series. The F/A-18E single-seat and F/A-18F tandem-seat variants are larger and more advanced versions of the F/A-18C and D Hornet.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
Northrop Grumman Electronic Systems (NGES) was a business segment of Northrop Grumman from 1996 to 2015 until a reorganization on January 1, 2016 merged other Northrop Grumman businesses into NGES to form a new segment called Mission Systems. NGES had originally been created by Northrop Grumman's acquisition of Westinghouse Electronic Systems Group in 1996. The Electronic Systems sector was a designer, developer, and manufacturer of a wide variety of advanced defense electronics and systems. The division had 120 locations worldwide, including 72 international offices, and approximately 24,000 employees; accounting for 20% of company sales in 2005.
The AN/APG-63 and AN/APG-70 are a family of all-weather multimode radar systems designed by Hughes Aircraft for the F-15 Eagle air superiority fighter. These X band pulse-Doppler radar systems are designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down at low-flying targets without being confused by ground clutter. The systems can detect and track aircraft and small high-speed targets at distances beyond visual range down to close range, and at altitudes down to treetop level. The radar feeds target information into the aircraft's central computer for effective weapons delivery. For close-in dogfights, the radar automatically acquires enemy aircraft and projects this information onto the cockpit head-up display. The name is assigned from the Army Navy Joint Electronics Type Designation System.
The AN/APG-79 is a type of active electronically scanned array (AESA) radar that was developed for use on the United States Navy's Boeing F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft. The radar's AESA technology provides quick updates on multiple targets, and its solid-state antenna construction makes it more reliable and cost-effective than traditional radar systems. The radar has a range of up to 150 km and can track multiple targets simultaneously. It is capable of firing weapons such as the AIM-120 AMRAAM and guiding multiple missiles to targets located at varying distances and directions. As of July 2008, 100 APG-79 sets had been delivered to the United States Navy, and the Navy expects to order around 437 production radars. In January 2013, the Director, Operational Test & Evaluation (DOT&E) disclosed some issues with the APG-79 radar during its initial operational testing, but upgrades have been made over time. The APG-79 has been selected for retrofitting the F/A-18 C/D and upgrading the fleets of F/A-18 fighters in Malaysia and the United States Marine Corps.
The AN/ALE-50 towed decoy system is an electronic countermeasure tool designed by Raytheon to protect multiple US military aircraft from air-to-air and surface-to-air radar-guided missiles. The AN/ALE-50 towed decoy system is an anti-missile countermeasures decoy system used on U.S. Air Force, Navy, and Marine Corps aircraft, and by certain non-United States air forces. The system is manufactured by Raytheon Space and Airborne Systems at its facility in Goleta, California. The ALE-50 system consists of a launcher and launch controller installed on the aircraft, and one or more expendable towed decoys. Each decoy is delivered in a sealed canister and has a ten-year shelf life.
The AN/ALQ-99 is an airborne electronic warfare system, found on EA-6B and EA-18G Growler military aircraft. The ALQ-99E version of the system was carried on the EF-111A Raven aircraft as an escort or standoff jammer.
The General Dynamics–Grumman EF-111A Raven is a retired electronic-warfare aircraft designed to replace the EB-66 Destroyer in the United States Air Force. Its crews and maintainers often called it the "Spark-Vark", a play on the F-111's "Aardvark" nickname.
Raytheon Intelligence & Space (RIS) is one of the four business segments of U.S. defense and aerospace conglomerate Raytheon Technologies. Headquartered in Arlington, Virginia, RIS has a total employment of 39,000 and 2019 sales of US$15 billion. Roy Azevedo is the segment's president.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing missiles by confusing the missiles' infrared guidance system so that they miss their target. Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm. The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile.
F/A-XX is a development and acquisition program for a future sixth-generation air superiority fighter to replace the United States Navy's F/A-18E/F Super Hornet and complement the F-35C beginning in the 2030s. A requirement was first identified in June 2008.
The AN/SPY-6 is an active electronically scanned array 3D radar under development for the United States Navy (USN). It will provide integrated air and missile defense for Flight III Arleigh Burke-class destroyers. Variants are under development for retrofitting Flight IIA Arleigh Burkes and for installation aboard Constellation-class frigates, Gerald R. Ford-class aircraft carriers, and San Antonio-class amphibious transport docks.
