The Aircraft Gateway Processor (AGP) is an Aircraft Survivability Equipment (ASE) controller contained within a single, flight qualified, Line Replaceable Unit. It integrates federated ASE sensors and countermeasures to provide a combined threat picture and prioritised tactical response per the user-programmed Pre-Flight Message (PFM). The AGP is installed by Boeing as aircraft ‘A’-Kit on all new and remanufactured AH-64D/E Apache Longbow Helicopters.
