Large Aircraft IR Countermeasures (LAIRCM)

The Large Aircraft Infrared Countermeasures (LAIRCM) program is designed to enhance the defensive capabilities of Department of Defense aircraft against man-portable air-defense systems (MANPADS). This initiative provides a robust countermeasure system that includes missile warning sensors, laser transmitter assemblies, and control interface units. These components work together to detect, track, jam, and counter incoming missile threats autonomously once powered up. The system is currently installed on over 1,200 aircraft across 54 different types. There are ongoing efforts to integrate it onto new platforms and improve its reliability and maintainability.

A key objective of the LAIRCM program is to continuously address and counter new and emerging threats through various upgrades. These upgrades encompass both hardware and software improvements, ensuring the system remains effective against evolving missile technologies. The Air Force Research Laboratory (AFRL) plays a crucial role in these efforts by conducting threat analysis and developing new infrared countermeasures concepts. This involves characterizing threat seekers, developing models for advanced infrared seekers, and assessing new technologies for potential incorporation into the LAIRCM system.

Modeling, simulation, and test activities are integral to validating the effectiveness of the LAIRCM system against real-world threats. These activities include evaluating infrared countermeasure techniques, developing jam codes, and conducting platform integration support tests. The program also focuses on predictive risk reduction tests before live missile fire testing or flight testing on aircraft. Additionally, Virtual System Integration Lab (SIL) development supports these objectives by providing a critical capability for testing software code in a virtual environment.

The program's acquisition strategy involves annual awards for existing contract options and government-led studies in collaboration with AFRL and other facilities like the Guided Weapon Evaluation Facility (GWEF). These partnerships facilitate comprehensive threat analysis research and modeling efforts to ensure the LAIRCM system's continued viability and sustainability. The program also explores opportunities to reduce costs while enhancing production efficiency through increased reliability and reduced repair expenses.
