AN/AAR-60 is an electro-optical missile and laser warning system developed for fast-jet and transport aircraft to detect and warn of infrared-guided threats. The system provides spherical coverage with sensors and processing to cue countermeasures, integrating with onboard defensive aids and warning suites. It has been fielded on multiple platforms and evaluated in exercises and operations involving allied air forces and defense contractors.
The program originated in response to requirements from the United States Navy, United States Air Force, and allied services seeking improved passive missile warning after experiences in the Yom Kippur War and Falklands War. Early development involved collaborations between defense contractors including Raytheon and smaller subcontractors, with prototype work influenced by lessons from the AN/AAR-47 family and technology demonstrations at Wright-Patterson Air Force Base. Design choices incorporated infrared focal plane arrays, digital signal processors tuned through test campaigns at sites such as Edwards Air Force Base and Nellis Air Force Base, and engineering reviews overseen by program offices in Patuxent River and Naval Air Systems Command personnel. Certification and qualification processes referenced standards used by NATO and testing frameworks from the Defense Advanced Research Projects Agency.
The system employs multiple infrared sensors with azimuth and elevation coverage to provide near-hemispherical detection, processing inputs through on-board electronics developed to MIL-STD and RTCA criteria. Detectors draw on cooled and uncooled focal plane technologies similar to those used in systems developed at MIT Lincoln Laboratory and by manufacturers in Los Angeles and Dallas. The processor architecture uses field-programmable gate arrays and real-time operating systems compliant with standards from IEEE and Joint Chiefs of Staff doctrines. Interfaces include digital databus connections compatible with MIL-STD-1553 and avionics integration protocols used on platforms such as the F/A-18 Hornet and C-130 Hercules. Environmental qualifications follow test regimens applied at Sandia National Laboratories and Arnold Engineering Development Complex.
Fielded examples have been integrated on a variety of tactical and strategic aircraft, including fighters, transports, and special-mission platforms supporting services such as the United States Navy, United States Air Force, and allied air arms from United Kingdom, Australia, and NATO partners. Operational deployments have taken place during joint exercises with units from Carrier Air Wing groups, Air Mobility Command operations, and coalition activities including deployments to regions where threats from infrared-guided missiles were assessed by commands like CENTCOM and EUCOM. Platform adapters and mission kits were developed in cooperation with OEMs responsible for aircraft such as the F-16 Fighting Falcon, P-3 Orion, and rotary-wing types operated by formations including Royal Air Force squadrons and Royal Australian Air Force units.
The system provides commissionable missile launch detection, angular localization sufficient to cue directional countermeasures, and laser warning for systems employing laser rangefinders or designators; performance metrics were derived from test events at ranges and engagement profiles similar to those modeled by analysts from RAND Corporation and Center for Strategic and International Studies. Detection algorithms incorporate false alarm mitigation influenced by studies from Sandia National Laboratories and pattern-recognition research from Carnegie Mellon University affiliates. Integration with expendable countermeasures and directed infrared countermeasure systems enabled coordinated responses evaluated in trials with units from Naval Air Station Fallon and Dover Air Force Base.
Integration pathways relied on open avionics standards used by primes like Boeing and Lockheed Martin, with software baselines controlled under configuration management practices familiar to Defense Logistics Agency processes. Maintenance procedures and logistics support followed maintenance doctrine promulgated by organizations such as Naval Air Systems Command and Air Force Materiel Command, with depot-level repair capabilities provided through contractor support agreements and regional sustainment hubs in locations including Tinker Air Force Base and contractor facilities in Florida and Massachusetts. Certification for airworthiness involved testing with authorities analogous to Federal Aviation Administration protocols when applied to civil transport variants.
Export control and foreign military sales were handled under processes involving U.S. Department of State and Defense Security Cooperation Agency review, with approved transfers to partners in NATO and security cooperation recipients in the Middle East and Indo-Pacific regions. Known operators include air arms of United Kingdom, Australia, several NATO members, and selected partners in Asia Pacific and the Gulf Cooperation Council, where systems were incorporated into national air defense architectures and coalition interoperability plans.
Operational evaluations and adverse event reports were compiled after live-fire and simulated engagements during exercises at ranges affiliated with Nellis Air Force Base and Sea Range trials, with assessments published internally by program offices and summarized in studies by institutions such as RAND Corporation and research teams from Johns Hopkins Applied Physics Laboratory. Specific incidents involving false alarms, sensor degradation, or platform integration challenges prompted software updates and hardware retrofits; corrective actions were executed under oversight comparable to Director, Operational Test and Evaluation processes and through contractor-led engineering change proposals reviewed at Patuxent River and allied test centers.
