During testing, IVEWS was exposed to highly accurate simulations of modern radio frequency (RF) threats in environments that closely mirrored real-world conditions. The system effectively detected, identified, and countered a full spectrum of radar-guided threats, delivering full RF protection and heightened situational awareness for combat missions.
IVEWS also demonstrated seamless digital interoperability with Northrop Grumman’s SABR radar. The two systems communicated on a pulse-by-pulse basis, ensuring mutual performance was preserved while enabling simultaneous electronic warfare and targeting functions.
Flight testing took place at Eglin Air Force Base in Florida and Nellis Air Force Base in Nevada. Installed on two F-16 Block 50 aircraft, IVEWS operated across more than 70 sorties, covering diverse mission types and environmental conditions.
“The team conducted more than 70 flights and 100-plus flying hours in a seven-month timeframe,” said Lt. Col. Christopher B. James, USAF, Deputy Division Chief, F-16 USAF Programs. “Not only did the system perform well, but it also worked during its first flight on two aircraft, which is unprecedented for a complex and fully integrated electronic warfare system.”
James added, “It has earned the slogan, ‘IVEWS, works first time, every time.’” These results validated earlier laboratory, chamber, and early flight test findings, reinforcing the system’s reliability and effectiveness.
“These successful flight tests showed the maturity and readiness of IVEWS to protect the F-16 fleet against the most advanced radio frequency threats,” said James Conroy, Vice President, Navigation, Targeting and Survivability at Northrop Grumman. “Modernising the Viper with the electronic warfare capabilities it needs to remain lethal and survivable for years to come.”
IVEWS is a fully digital solution based on open systems design principles, offering ultra-wideband architecture, millimetre wave coverage, 360-degree spatial awareness, and operationally relevant geolocation. The system represents Northrop Grumman’s commitment to supporting global customers in modernising their forces to address evolving threats in complex electromagnetic environments.
