The AN/AAR-47 Missile Warning System is a Missile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft's countermeasures systems.

The AN/AAR-47 is a fielded, combat deployed, electronic warfare system designed to protect aircraft against infrared-guided (IR) missile threats, laser-guided/laser-aided threats, and unguided munitions.

Employed on helicopters and transport aircraft, the AAR-47 Missile Approach Warning System (MAWS) warns of threat missile approach, enabling the effective employment of evasive maneuvers and electronic and infrared countermeasures.

Our ALE-47 system is operating as the standard advanced aircraft countermeasures dispense system for the U.S. Air Force, U.S. Army, U.S. Marine Corps, and U.S. Navy, as well as international allies, providing next-generation technology throughout the globe.

The AN/AAR-47 is a passive, missile-approach warning system consisting of four IR sensor assemblies, a central processing unit and a control indicator capable of detecting missile launches from 360 degrees around the aircraft. 2. Requirement. 3. Impacts if Not Funded.

The AAR-47(V)2 upgrade has improved UV single-pixel quadrant sensors that eliminated sensor blackening (a known failure mode), increased temperature tolerance, provided a more uniform...

Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to disrupt missile tracking. Guided surface-to-air missile (SAM) systems were developed during World War II and began to make their presence felt in the 1950s.

Deployed on helicopters and transport aircraft, the AAR-47 deals with threat missile approach by detecting radiation associated with the rocket motor, letting the crew know that an attacking missile is coming and which direction it’s coming from, and automatically firing decoy flares.

The AN/AAR-47 was developed to provide awareness about surface-to-air missile firings to both helicopters and low flying aircraft. It also automatically provides countermeasures (ALE-39, ALE-40 or ALE-47) and visual and audio sector warning messages to the pilot.

Detection algorithms are used to discriminate against non-approaching radiation sources. The AAR-47 is a passive, missile- approach warning system consisting of four sensor assemblies housed in two or more sensor domes, a central processing unit, and a control indicator.
