The US Air Force’s Integrated Viper Electronic Warfare Suite (IVEWS) has completed its Operational Assessment flight testing, manufacturer Northrop Grumman announced.
Flight tests took place in Florida and Nevada, where two F-16 Block 50s installed with the suite demonstrated stable performance over more than 70 sorties.
Simulations included in the test covered a wide range of environmental conditions and mission scenarios, including air-to-air, air-to-ground, and mixed threat engagements.
The IVEWS also successfully detected, identified, and countered complex modern radio frequency threats.
Northrop Grumman navigation, targeting, and survivability vice president James Conroy stated that the success of the IVEWS cements the suite’s effectiveness in improving survivability for fourth-generation platforms.
“These successful flight tests showed the maturity and readiness of IVEWS to protect the F-16 fleet against the most advanced radio frequency threats – modernizing the Viper with the electronic warfare capabilities it needs to remain lethal and survivable for years to come,” he said.
The flight tests now clear the suite for production and fielding for the air force. Up to 450 F-16s will be equipped with the suite.
An Adapting Platform
Designed to compete with suites on fifth-generation aircraft, the IVEWS includes a next-generation digital radar warning receiver, as well as an advanced processor designed specifically for electronic warfare applications.
The fully digital technology cleared its ground testing last September after showcasing its ability to detect, identify, and counter advanced radio frequency threats while operating safely with other F-16 systems.
Northrop Grumman developed the IVEWS after winning an 18-month “unpriced” contract to create an electronic warfare platform in 2022.
