The F-15E Eagle fleet is currently undergoing critical electronic warfare testing at the Benefield Anechoic Facility (BAF) on Edwards Air Force Base, California. This F-15E is outfitted with the Eagle Passive/Active Warning and Survivability System (EPAWSS). The EPAWSS is an integrated digital avionics system designed to protect the F-15E Eagle against enemy air defense systems, said Jon Danner, F-15 Division Test Manager at Air Force Life Cycle Management Center.
