ROLLING MEADOWS, Ill. – April 11, 2023– Northrop Grumman Corporation’s (NYSE: NOC) AN/ALQ-257 Integrated Viper Electronic Warfare Suite (IVEWS) has completed U.S. Air Force Laboratory Intelligence Validated Emulator (LIVE) testing. The system exceeded multiple benchmarks and demonstrated the ability to counter modern radio frequency (RF) threats. This was the first time the ultra-wideband architecture in IVEWS underwent LIVE testing.

“As advanced radio frequency threats continue to proliferate, the protection afforded by IVEWS is essential,” said James Conroy, vice president, navigation, targeting and survivability, Northrop Grumman. “This successful evaluation under very challenging conditions is an important step on the path to fielding the suite.”

During the test, simulated air defense radar pulses were injected directly into IVEWS to verify the suite’s ability to recognize and counter advanced threats. The signals used in LIVE testing are validated models that provide realistic representations of radio frequency threats. LIVE is an intelligence validated, closed-loop RF direct-injection threat radar emulator based on threat capabilities and features. It allows for the testing electronic warfare systems in realistic environments.

Fully digital and founded on secure, modular, open systems design principles, the receiver/exciter architecture in IVEWS provides significant advantages over heritage systems. This technology allows for extended frequency coverage, full spatial coverage, and more rapid responses. Featuring highly efficient broadband power amplifiers and adaptive countermeasure modulations, it is designed to detect, identify, locate, and defeat next generation sensors and weapons. 

IVEWS is a program of record electronic warfare suite for the U.S. Air Force F-16 fleet. The system is exportable for current and previous generations of F-16 aircraft.
