The U.S. Air Force has completed the first installation of Telephonics‘Â AN/UPX-40Â “identification friend or foe” interrogation system onto the Boeing-builtÂ E-3 Sentry Airborne Warning and Control System aircraft.
Justin Oakes wrote July 28Â that the Air Force will equip its entire fleet of 31Â AWACS aircraft with the new interrogationÂ system, which replacesÂ AN/APX-103C and featuresÂ Mode 5 Interrogation upgrades.
Nick Grudziecki, deputy program manager at theÂ AWACS Next Generation IFF program office atÂ Hanscom Air Force Base, saidÂ AN/UPX-40 works to detect even weak signals orÂ maneuvering targets at all ranges.
“The new interrogation capabilities also provide faster detection of friendly targets,” he added.
Eight more AN/UPX-40 installations are scheduled through the end of the year, Oakes reports.
The report said the interrogation system upgrade is part of the largerÂ Block 40/45Â AWACS modernization effort.
