There is one optical sensor converter for each side of the aircraft. They have an infrared camera for detecting incoming missiles. The
Optical modules since version AAR-47(V)2 include a laser warning sensor, and versions since AAR-47A(V)2 further incorporate an ultraviolet sensor for improved dynamic

The AN/AAR-47 is a line of missile warning systems by Loral and ATK Alliant
Techsystems. The development of the original AN/AAR-47(V)1 began in 1983 by Loral. ATK became a second production source in the mid 90s and eventually became the prime contractor. In 1998 ATK began production of the improved

The system's algorithms include looking for temporal variations in a signal's strength, such as the brightening of an incoming missile. It also evaluates the spectral bandpass of the threat to reduce false alarms and has software for detecting events, such as the launch of a

The computer processor evaluates the data from the OSC:s and analyzes whether a detected event is an incoming missile. If a threat is detected, it sends a signal to the control indicator which informs the crew, and the aircraft's infrared countermeasures system.

AN/AAR-47(V)2 version, which added laser warning functionality. As of 2005, over 5000 of these sets have been manufactured. In 2006, production of the AN/AAR-47A(V)2 began, also developed by ATK. It has further improved missile and laser warning capabilities.

and are capable of detecting a wider range of threats. After processing the nature of the threat, the system gives the pilot an audio and visual warning, and indicates the direction of the incoming threat. It also sends a signal to the aircraft's

The AAR-47 missile warning system consists of 4 Optical Sensor
Converters (OSC), a Computer Processor and a Control Indicator. The system is relatively light at a total weight of approximately 32 pounds.
