In addition, the upgrade will provide for increased processing power to enable better operation of the fleet’s advanced battle management tools, such as Automatic Air Tasking Orders and Airspace Co-ordination Order updates. The aircraft’s Multi-Sensor Integration (MSI) process, which automatically integrates data from on- and off-board sources such as radar and identification friend-or-foe (IFF) systems, electronic support measures, and Link 16, is also upgraded under the process, with the MSI’s open system and lean architecture enabling rapid software upgrades and requiring less hardware. As part of the upgrade the US Air Force (USAF) is also replacing the E-3’s AN/APX-103C radar with the AN/UPX-40, which was designed to eliminate ground clutter to better detect, identify, and track low-flying aircraft.
