Core Avionics Master Plan 2011 Appendix A-6radar-guided missile threats. The system is installed in pylons on Foreign Military F/A-18 and F-16 aircraft, installed with the AN/ALQ-126B in the AN/ALQ-164 pod on USMCand Foreign Military AV-8B aircraft, and internally mounted in a variety of U.S. Armyrotary wing aircraft. The system operates in a stand-alone or EW Suite mode. In the EWSuite mode, the AN/ALQ-126B interfaces with the Radar Warning System (RWS) in acoordinated, non-interference manner sharing information for enhanced operation in anon-interference basis. An upgraded version of the system, ALQ-162(V)6, wasdeveloped and produced via a joint Foreign Military Sales initiative to add Digital RadioFrequency Memory (DRFM)-based, pulse Doppler radar jamming capability andincreased transmitted power using a Microwave Power Module (MPM). The AN/ALQ-164(V)6 configuration is installed in F-16 pylons and internally aboard AH-64D Apachehelicopters.The AN/ALQ-165, the Airborne Self-Protection Jammer (ASPJ) is an airborneDECM, a programmable modular automated system capable of intercepting, identifying,processing received radar (pulse and continuous) signals and applying an optimumcountermeasures technique, thereby improving individual aircraft probability of survivalagainst a variety of surface-to-air and air-to-air RF threats. The system operates in avariety of host aircraft in stand-alone or EW Suite mode. In the EW Suite mode, theAN/ALQ-165 interfaces with the RWR in a coordinated, non-interference manner. TheAN/ALQ-165 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.The AN/ALQ-214 is the onboard jammer (OBJ) an advanced airborne IDECMprogrammable 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. In the EW Suite mode, theAN/ALQ-214 operates in a fully coordinated mode with the towed dispensable decoy,Radar Warning Receiver (RWR), various dispensers, and the on-board radar in the F/A-18E/F in a coordinated, non-interference manner sharing information for enhancedoperation. The AN/ALQ-214 was designed to operate in a high density electromagnetichostile environment with the ability to identify and counter a wide variety of multiplethreats including those with Doppler characteristics.2. Funded Enhancements and Potential Pursuits.On-Board Jammer Enhancements. (2011) 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 Proposals (ECP) for the block III and block IV effectively alter the ALQ-214onboard jammer to a Modular Open Systems Architecture (MOSA) and institutes size,weight and power reductions along with other upgrades.A-6 Self Protection 6
Core Avionics Master Plan 2011 Appendix A-6Reel Out – Reel In (RORI) decoy. (2012) S&T efforts are underway to integrate aReel Out – Reel In (RORI) towed decoy launcher that will increase the tow envelopeand provide for reuse of a deployed towed decoy. The RORI effort will be integratedwith the ALE-55 towed decoy.C. Radar Protection.1. Current capabilities.The AN/ALR-67(V)2 Radar Warning Receiver (RWR) has provided warningcapability for both US and foreign military aircraft since 1982. It has three different typesof receivers; a broadband crystal video receiver, a super-heterodyne receiver, and anintegrated low-band receiver. It also has an antenna array and an azimuth indicator,which are controlled by a CP-1293C threat processor. The AN/ALR-67(V)2 wasproduced by Northrop Grumman and is used in the F/A-18, and AV-8B aircraft. Theforeign military sales (FMS) of this system has implemented diminishing manufacturingsources and material shortages (DMSMS) programs to maintain system operationalcapabilities 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. As is true of its predecessor, the AN/ALR-67(V)2, the purpose of theRWR is to detect, identify, and localize the radar of potentially threatening weaponsystems. Contracted for development in 1989 to Hughes Aircraft Company (nowRaytheon), the AN/ALR-67(V)3 uses channelizer rather than Crystal Video Analog-todigital(CVAD) technology. The system has added millimeter wave capability, whileretaining low band and the 4-quadrant high band microwave capabilities. The high bandantennas are an improvement over the AN/ALR-67(V)2 antennas.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.The 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 withintegrated avionics bus processing, the AN/APR-39B(V)2 acts as the 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 Missile Warning Set, andAN/ALE-47 Countermeasures Dispenser. The AN/APR-39B(V)2 acts as the integrationprocessor for the federated ASE sensor suite.The processor stack has an additional 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).A-6 Self Protection 7
