Northrop Grumman Unleashes Cutting-Edge EW and Radar Innovations for the F-16

Nurturing Air Superiority: The Power of Northrop Grumman’s IVEWS and SABR

Northrop Grumman’s Integrated Viper Electronic Warfare Suite (IVEWS) paired with the Scalable Agile Beam Radar (SABR) Active Electronically Scanned Array (AESA) radar presents formidable enhancements for the F-16 fighter jet. When combined, these advanced systems deliver unparalleled survivability and lethality, elevating the Viper’s operational capability.

Optimizing the Electromagnetic Spectrum

Fighter jet radars and electronic warfare (EW) systems leverage the radio frequency segment of the electromagnetic spectrum for effective targeting, self-defense, and surveillance missions. Northrop Grumman specifically engineered the F-16’s IVEWS to synchronize effortlessly with the SABR AESA radar, enabling simultaneous use of the same spectrum portion.

Enhanced Survivability for Superior Lethality

“To dominate the electromagnetic spectrum is to gain the upper hand in all operations,” stated James Conroy, VP of electronic warfare and targeting. “In high-pressure scenarios, interconnected systems provide a substantial advantage, allowing warfighters to operate securely and efficiently within contested airspaces.”

IVEWS ensures seamless protection for the platform without filtering or diminishing radar capabilities. The systems communicate on a pulse-to-pulse basis, enabling each to monitor the spectrum usage of the other continuously. This coordination empowers pilots to perform intricate radar operations without hindering IVEWS’ ability to counter threats.

Addressing Modern Threats with Innovative Solutions

Global threats are evolving, becoming more agile and unpredictable. The combat landscape now comprises mobile threats that can swiftly alter frequencies. An effective EW system must detect, identify, and jam threats as aircraft approach weapon range, not just within detection zones.

“We engineered IVEWS with ultra-wideband architecture and sufficient onboard power to recognize and mitigate advanced threats,” remarked Conroy. “The U.S. and its allies face these challenges globally.”

Chosen by the U.S. Air Force in 2019, IVEWS has successfully completed Operational Assessment, flying over 70 sorties under complex electromagnetic conditions. In total, Northrop Grumman has delivered more than 900 SABR systems since 2013.

Proven Performance: IVEWS Delivers Consistent Results

IVEWS proved its readiness from the outset during the Air Force’s Northern Lightning exercise in 2021, effectively operating alongside SABR in a saturated electromagnetic environment against both airborne and ground threats. Following rigorous laboratory and chamber tests, it was installed on two USAF F-16 aircraft, leading to successful developmental tests and operational assessments.

According to Lt. Col. Christopher B. James, USAF, Deputy Division Chief for F-16 Programs, “Our collaboration between the USAF F-16 System Program Office, Northrop Grumman, Lockheed Martin, and our partners has yielded excellent results during the IVEWS Operational Assessment. Remarkably, the system performed effectively during its inaugural flight on both aircraft, setting a precedent for integrated electronic warfare systems.”

Post-assessment, IVEWS has continued to conduct missions against a diverse range of airborne, maritime, and ground threats, showcasing its unmatched capability to safeguard maneuverability while protecting warfighters. It has now accumulated over 250 flight hours.

Crafted and produced in the USA, both IVEWS and SABR are equipped to safeguard the global fleet of over 2,800 F-16 aircraft. These advanced electronic warfare systems place the F-16 a generation ahead, delivering unmatched capabilities without compromise.
