The Electronic Warfare Directorate is the Air Force focal point for electronic warfare (EW) test and evaluation. It provides the world's preeminent test and evaluation capabilities, resources, and expertise for EW and avionic systems.

The Electronic Warfare Directorate has full electronic warfare test and evaluation capabilities to meet mission-specific requirements. Extensive test facilities include the Test and Evaluation Modeling and Simulation

facility, systems integration laboratories for software test and integration, hardware-in-the-loop facilities to evaluate the effectiveness of EW systems and tactics, and installed systems test facilities, such as the Benefield Anechoic Facility. Open air ranges, flight test, and measurement facilities provide antenna performance and aircraft radio frequency and infrared signature test and evaluation capabilities.

These test facilities provide operator-in-the-loop and hardware-in-the-loop laboratories to evaluate hardware and software interactions, piloted real-time and non-real-time simulations of air vehicle performance, flying qualities and flight control systems. Installed systems testing is performed in the Benefield Anechoic Facility, the world's largest known anechoic chamber.
