The AN/ALQ-257 Integrated Viper Electronic Warfare Suite (IVEWS) to be integrated into the F-16 has completed ground tests and begun flight tests. It is said that the system will provide the F-16 with electronic warfare capabilities equal to 5th generation aircraft. Turkey announced that it would procure more than 150 of these systems along with the F-16 Block 70 purchase and signed a letter of agreement with Northrop Grumman to modernize its old aircraft with IVEWS. Turkey also became the first country to procure these systems after the United States. James Conroy, vice president of navigation and targeting at Northrop Grumman, said the system could help maintain Viper reliability into the 2040s.
Northrop Grumman emphasizes that this system works seamlessly with the APG-83 SABR. The two working together without compromising the performance of the radar is quite deadly.
