Using DRFM, an adversary can swiftly replicate signals, allowing for fast and accurate jamming in the air battle. Though ACC officials say TEWS "lacks performance to counter current/future threats," Epawss introduction into service is beyond the future years defense plan, or beyond 2020. Installs for developmental testing aircraft are slate...
