PMA209 2012 Core Avionics Master Plan - NAVAIR - U.S. Navy

Core Avionics Master Plan 2012 Appendix A-6finding and interfaces directly to the AN/ALE-39/47 countermeasures dispenser.Detection algorithms are used to discriminate against non-approaching radiationsources. The AN/AAR-47 is a passive system consisting of four sensor assemblieshoused in two or more sensor domes, a central processing unit, and a control indicator.Recent development of AAR-47B(V)2 increase the probability of missile warningdetection in harsh, UV-cluttered operating environments.As the first fielding of a directed energy weapon system, the AN/AAQ-24(V)25Department of Navy (DoN) Large Aircraft Infrared Countermeasure (DoN LAIRCM)program provides a laser-based, directed infrared countermeasure (DIRCM) solution toincrease the survivability of Marine Corps rotary wing assault aircraft against IR guidedthreats. The DoN LAIRCM system is an upgrade to the Air Force's AN/AAQ-24 LAIRCMmissile warning system developed by the USAF. DoN LAIRCM integrates 2-color IRmissile warning sensors with the improved Guardian Laser Transmitter Assemblies. TheDoN LAIRCM system is designed to provide CH-53E (lead) and CH-46E platforms withself-protection against IR guided surface-to-air missiles by detecting their signaturesand defeating them with laser jamming. The DoN LAIRCM system successfullydemonstrated Early Operational Capability in November 2009 and was approved forlimited fielding of 32 systems on CH-53E aircraft in support of Operations OIF and OEF.DoN LAIRCM capable CH-53Es are currently flying operational missions in-theater. Thetwo-color IR sensor in DoN LAIRCM will undergo an upgrade in 2012 to be able todetect hostile fire from unguided munitions. Due to size, weight and power restrictions,this system is not being considered for smaller platforms. The Army CIRCM programdevelopment is being conducted in close cooperation with the PMA-272 program officesince the CIRCM will be procured for inclusion onto Navy and Marine Corps aircraft withthe MV-22 as the lead platform for the Navy's efforts.2. Funded Enhancements and Potential Pursuits.Joint and Allied Threat Awareness System (JATAS). (IOC 2015) The nextgeneration MWS will be the Joint and Allied Threat Awareness System (JATAS) whichcommenced a competitive Engineering and Manufacturing Development phase with asingle vendor in 2011. JATAS, in its final form, will be a two-color IR sensor that willprovide integrated missile warning, laser warning, situational awareness and HFI forAssault Support aviation. Intended host platforms include the MV-22B, AH-1Z, UH-1Y,MH-60R/S. The system will be developed with Modular Open Systems Architecture(MOSA) to enable upgrade, technology refresh and integration with other platforms. PerSECDEF guidance, the Navy is the lead Service and is working closely with theprogram office of the Army (Program Directorate ASE) in the development of JATAScapabilities and interfaces to meet inter-Service transfers of this system onto Armyplatforms.Advanced Threat Warning (ATW). (IOC 2012) The DoN LAIRCM 2-color sensorwill undergo an engineering change to attain the capability for hostile fire warningthrough a change in processor, high speed detector chip and software.Guardian IRCM Pod upgrade. (IOC 2013) Using assets from a 2004-2007Department of Homeland Security commercial airline IRCM program, PMA-272 willupdate and convert several pods in 2012 for demonstration as a pilot program toexpand the IRCM capability to fixed-wing airframes. PMA-207 is the transition partnerto outfit common-user aircraft.A-6 Self Protection 8
