Large Aircraft Infrared Countermeasures

The Large Aircraft Infrared Countermeasures (LAIRCM) program is designed to enhance the defensive capabilities of Department of Defense aircraft against infrared-guided missile threats, such as man-portable air defense systems (MANPADS) and surface-to-air missiles (SAMs). The system is fully autonomous after power-up and includes missile warning sensors, a laser transmitter assembly, and processors that detect, track, and counter incoming missiles. The program aims to maintain a robust reliability framework that incorporates enhancements to improve producibility and long-term sustainment.

The LAIRCM program supports various efforts including hardware procurement, installation support, initial spares, support equipment, and repairs. It also addresses issues related to diminishing manufacturing sources (DMS) by implementing substitutes or redesigning components as needed. The program office has initiated multiple DMS efforts to ensure the continued production of LAIRCM components for all customers. These efforts include securing existing supply availability, qualifying substitutes, and redesigning equipment when necessary.

Specific objectives for the LAIRCM program include completing installations on C-130J aircraft and procuring kits for AC-130J aircraft. Additionally, the program supports interim contractor support repairs for platforms and addresses DMS management issues. The KC-135 effort continues to support procurement of podded solutions for the Air National Guard and Air Reserve Components. Allocations are made to ensure timely delivery of required kits and installations across various aircraft models.

The LAIRCM program seeks to provide comprehensive protection for strategic aircraft by integrating advanced countermeasure technologies. This involves continuous updates to technical data, qualification testing, and non-recurring engineering costs for equipment updates. By addressing both current operational needs and future sustainment challenges, the program aims to maintain a high level of readiness and effectiveness in countering infrared missile threats.
