Core Avionics Master Plan 2011 Appendix A-6The AN/ALE-47, an expendable countermeasures dispensing system, protects thehost aircraft in a multi-threat environment. The AN/ALE-47 CMDS provides expendablecountermeasures dispensing capability through the use of programmable dispenseprograms and parameters that are programmable through a Memory Loader/Verifier Set(MLVS) over a MIL-STD-1553 type data bus. It is capable of full integration with thedefensive avionics suite of the host aircraft for automatic threat-adaptive dispensing ofexpendable countermeasures. It can be operated independent of any other avionicssystem in a manual mode for direct pilot control in the event of interfacing equipmentfailure, non-availability or mission requirements. The AN/ALE-47 has four operationalmodes to dispense expendables: manual, bypass, semi-automatic, and automatic. Inthe automatic and semi-automatic modes, the AN/ALE-47 receives threat informationfrom the threat sensors and uses the data to calculate dispense program parametersusing a “cocktail” of expendables to implement against specific threat(s). The AN/ALE-47 also has up to six manual dispense programs that the pilot/aircrew can release. TheCMDS provides the aircraft with an expendable countermeasures capability against RF,IR, and EO threats from Anti-Aircraft Artillery (AAA), Surface-to-Air Missiles (SAMs), Airto-AirMissiles (AAMs), and Airborne Interceptors (AIs). The CMDS design isprogrammable that will allow the system to counter future threats when deployedthrough mission data file modification, which increases capability with newly developedexpendables and dispensing sequences (a.k.a. cocktails) that will meet the threat.The F/A-18 T3F Launcher for the AN/ALE-50A and the AN/ALE-55 AdvancedAirborne Expendable are designed to seduce incoming RF-guided missiles away fromthe aircraft in the endgame phase of an enemy missile's flight. The decoys are launchedwhen needed and towed behind the host aircraft until it is severed before landing. TheAN/ALE-55 is an advanced Fiber Optic Towed Decoy (FOTD) that is capable of moreadvance techniques than the AN/ALE-50. Both Decoys use the version of the AN/ALE-50A. The complete system uses the Integrated Multiple Launch Controller (IMPLC)Dispenser and the towed decoy.IR Countermeasures: The IR decoy is a device designed to provide an alternativeheat source and seduce the threat missile away from the aircraft towards the flare. Itsfunction is to act as a false target or decoy to the approaching heat-seeking missile.When dispensed from the target platform, the flare falls away in such a way as to divertthe threat missile from the target. Because of the complexity of advance threat missilesand the lack of Situational Awareness (SA) about which missile type is inbound,comprehensive techniques utilizing multiple decoys must be devised and tailored foreach type aircraft.RF Passive Countermeasures: Chaff is one of the most widely used and effectiveexpendable self-protection devices. It is a form of volumetric radar clutter consisting ofmultiple metalized radar reflectors designed to interfere with and confuse radaroperation. It is dispensed into the atmosphere to deny radar acquisition, generate falsetargets, and to deny or disrupt radar tracking. Chaff is designed to be dispensed from anaircraft and function for a limited period.Active RF Expendable Jammers: Active RF expendable jammers are designed toprovide endgame protection for tactical aircraft against surface-to-air and air-to-air radarguided missiles.A-6 Self Protection 4
Core Avionics Master Plan 2011 Appendix A-62. Funded Enhancements and Potential Pursuits.Power PC Processor. (2010) The AN/ALE-47(V) currently uses a 16-bit MIL-STD-1750A Central Processing Unit as the main processor. Due to the age of thearchitecture, the 1750A does not provide the needed growth or capability required of theAN/ALE-47 in future years. Availability, memory restrictions, throughput restrictions andincreased maintenance costs are all mission vulnerabilities created by the continueduse of the 1750A processor. In order to reduce these mission vulnerabilities theDepartment of the Navy is planning to replace the 1750A CPU with a Power PCprocessor. The AN/ALE-47(V) can be integrated with on-board systems to receiveaircraft attitude, altitude and airspeed as well as threat angle of arrival, range, etc. Thecapability to use these parameters to optimize dispense program effectiveness andexpendable consumption, also known as Smart Dispensing, is being pursued for aircraftwith integrated systems.Enhanced Expendables. (2011) The expendables used in the AN/ALE-47dispenser system are constantly being upgraded with technological enhancements toimprove safety, reliability or producibility, and to increase their effectiveness against theadvanced IR and RF threat. A replacement for the GEN-X Electronic Decoy is currentlybeing studied to provide a capability required for future contingencies. Advances inpyrotechnic and pyrophoric type decoys are being pursued to enhance countermeasureeffectiveness, centered on defeating the counter-countermeasures of the advanced IRMANPAD, including tailoring the spectral output, output in different bands, improvingaerodynamic qualities and improving kinematic performance. The expendable dispensetechniques are as important to defeat the advanced threat as the expendables, so acontinuous effort is required to derive, test and field more sophisticated, effectivetechniques. To this end, the program office has added a program element called AircraftSurvivability Program Optimization (ASPO) funding line in the budget to optimize threatresponse techniques and tactics, increase modeling and simulation efforts and toincrease in-field ASE grooming. ASPO will help meet future threats that demandexpendables and directed energy solutions be synergized.B. Electronic Countermeasures.1. Current capabilities.The AN/ALQ-126B is a programmable airborne Defensive ElectronicCountermeasures (DECM) system capable of intercepting, identifying, and processingreceived radar pulse (only) signals and applying an optimum countermeasurestechnique, thereby improving individual aircraft probability of survival against a variety oflegacy surface-to-air RF threats. The system operates in a variety of host aircraft in astand-alone or EW Suite mode. In the EW Suite mode, the AN/ALQ-126B interfaceswith the Radar Warning Receiver (RWR) in a coordinated, non-interference mannersharing information for enhanced operation in a non-interference basis.The AN/ALQ-162(V)1 is a programmable airborne Defensive ElectronicCountermeasures (DECM) system capable of intercepting, identifying, and processingreceived Continuous Wave (only) radar signals and applying an optimumcountermeasures technique in the direction of the radar signal; thereby, improvingindividual aircraft probability of survival against a variety of active and semi-active RFA-6 Self Protection 5
