Core Avionics Master Plan 2012 Appendix A-6The AN/ALQ-214 is the onboard jammer (OBJ) an advanced airborne IntegratedDECM programmable modular automated system capable of intercepting, identifying,processing received radar signals (pulsed, pulsed Doppler, and continuous wave) andapplying an optimum countermeasures technique, thereby improving individual aircraftprobability of survival against a variety of surface-to-air and air-to-air RF threats. Thesystem operates in a stand-alone or EW Suite mode. The AN/ALQ-214 Block IIIUpgrade is the current baseline system and works with the AN/ALE-55 fiber FOTD. TheAN/ALQ-214 was designed to operate in a high density electromagnetic hostileenvironment with the ability to identify and counter a wide variety of multiple threatsincluding those with Doppler characteristics.2. Funded Enhancements and Potential Pursuits.On-Board Jammer Enhancements. (2012) The ALQ-214 is being modified torender it suitable for carrier-based operations, when installed in the F/A-18C/D, whileretaining full functionality, to include driving the AN/ALE-55 FOTD, when installed in anF/A-18E/F. This modified design will provide F/A-18C/D aircraft the capability to detectand respond to pulsed, pulsed Doppler, and continuous wave threats. This EngineeringChange Proposal (ECP) for block IV effectively alters the ALQ-214 onboard jammer to aModular Open Systems Architecture (MOSA) and institutes size, weight and powerreductions along with other upgrades.C. Radar Protection.1. Current capabilities.The AN/ALR-67(V)2 RWR has provided warning capability for both US and foreignmilitary aircraft since 1982. It has three different types of receivers; a broadband crystalvideo receiver, a super-heterodyne receiver, and an integrated low-band receiver. Italso has an antenna array and an azimuth indicator, which are controlled by a CP-1293C threat processor. The AN/ALR-67(V)2 was produced by Northrop Grumman andis used in the F/A-18, and AV-8B aircraft. The FMS version of this system hasimplemented diminishing manufacturing sources and material shortages (DMSMS)programs to maintain system operational capabilities as this system ages.The AN/ALR-67(V)3 is the newest generation RWR and is installed in the F/A-18E/FSuper Hornet. The purpose of the RWR is to detect, identify, and localize the radar ofpotentially threatening weapon systems. Contracted for development in 1989 to HughesAircraft Company (now Raytheon), the AN/ALR-67(V)3 uses channelizer rather thanCrystal Video Analog-to-digital (CVAD) technology. The system has added millimeterwave capability, while retaining low band and the 4-quadrant high band microwavecapabilities. The high band antennas are an improvement over the AN/ALR-67(V)2antennas.The AN/APR-39A(V)2 is a multi-service Radar Signal Detection Set (RSDS) and isone of the most widely used RWRs in the world. The RSDS detects, determinesdirection, classifies, and provides audible and visual cues to the aircrew when radarsignals illuminate the platform. A key feature of the AN/APR-39A(V)2 is areprogrammable memory unit that stores a Mission Data Set (MDS) containing radarsignatures and processing information specific to the geographical area of operation.A-6 Self Protection 6
Core Avionics Master Plan 2012 Appendix A-6The MDS determines how signals are classified and prioritized, and associatesaudible messages and visual symbols that will be displayed to the aircrew. TheAN/APR-39A(V)2 can operate independently, providing audible alerts over the platformaudio bus, and symbols on the IP-1150A display. The RSDS has been upgraded to theAN/APR-39B(V)2 configuration for the U.S. Navy and Air Force on aircraft (such as theAH-1Y or AH-1Z) with integrated avionics bus processing, the AN/APR-39B(V)2 acts asthe EW bus controller, polling and controlling other Aircraft Survivability Equipment(ASE) on the platform, including the AN/AVR-2 Laser Detecting Set, AN/AAR-47 MissileWarning Set, and AN/ALE-47 Countermeasures Dispenser. The AN/APR-39B(V)2 actsas the integration processor for the federated ASE sensor suite.The processor stack has an upgraded interface card inserted to allow the system tobe a receiver/transmitter on a MIL-STD-1553 data bus. The AN/APR-39B(V)2 providesRSDS status and symbol display information via the data bus for use on aircraftequipped with integrated avionics processors and Multi-Function Displays (MFDs).2. Funded Enhancements and Potential Pursuits.The program office has obtained FY10/11 funding to replace existing ALR-67(V)2with the newer ALR-67(V)3 in lieu of pursuing continued DMSMS solutions.Processor Upgrades. (2015) The AN/APR-39A/B(V)2 is being upgraded forsustainability and to meet emerging DECM requirements. The AN/APR-39C(V)2processor upgrade will replace seven circuit card assemblies with three modernizedprocessor cards to increase the processing speed and emitter library memory size. TheAN/APR-39C(V)2 will also incorporate an AN/AAQ-24(V)25 Directed InfraredCountermeasure (DIRCM) interface for improved pilot awareness and systemmanagement. Further planned improvements (i.e. AN/APR-39D(V)2) will include:replacing the analog-tuned receiver with a digital receiver and replacing the spiralantennas with dual-pole spiral antennas which will increase the probability of detectionof pulse-Doppler radars, cross-pole/circular polarization and improve accuracy of Angleof-Arrival(AOA). These enhancements will provide for the operational viability of theAN/APR-39 well into the 21 st century and preclude impending DiminishingManufacturing Sources (DMS). The AN/APR-39, with technology upgrades, is wellpositioned to be the ASE central processor and will act as the platform’s EW buscontroller.D. Missile Protection.1. Current capabilities:The AN/ALQ-144 Omni-Directional IR Jammer is pre-emptive jammer to protectrotary wing platforms from early generation IR seeking missiles. The Navy and MarineCorps have made a decision to retain this system on aircraft where installed while otherIRCM efforts mature.Deployed on helicopters and transport aircraft, the AN/AAR-47 Missile WarningSystem (MWS) warns of threat missile approach by detecting ultraviolet radiationassociated with the rocket motor and automatically initiates flare dispense. In 2011, theAAR-47 algorithm update included the ability to detect small arms fire, a.k.a. hostile fireindication (HFI). The MWS provides attacking missile declaration and sector directionA-6 Self Protection 7
