Common Infrared Countermeasures (CIRCM)

The Common Infrared Countermeasures (CIRCM) program is a vital part of the Army's strategy to improve aircraft survivability against missile threats. This initiative centers on developing and integrating advanced Aircraft Survivability Equipment (ASE) for rotary-wing, tilt-rotor, and small fixed-wing aircraft. CIRCM is designed to function alongside systems like the Common Missile Warning System (CMWS) and the Limited Interim Missile Warning System (LIMWS), using a laser-based infrared countermeasure to disrupt missile tracking capabilities. The program aims to protect Army aircraft from current and emerging threats by employing an Open Systems Architecture that facilitates ongoing software and hardware updates.

A primary goal of the CIRCM program is the development of A-Kits and B-Kits, which are crucial for installing and operationally integrating the countermeasure systems on various aircraft platforms. The A-Kit includes essential mounting hardware and wiring harnesses, ensuring compatibility with specific aircraft types. Meanwhile, the B-Kit consists of critical components such as lasers and pointer trackers, providing near-spherical coverage to effectively counter missile threats. These kits are integral to the Future Vertical Lift (FVL) platform's mission equipment suite, supporting both current and future Army aviation needs.

Beyond its main development objectives, CIRCM also addresses urgent operational requirements through initiatives like the Joint Urgent Operational Needs Statement (JUONS) SO-0010. This effort involved integrating the Department of Navy Large Aircraft Infrared Countermeasure (DoN LAIRCM) system onto Army platforms, particularly for Special Operations Aircraft. The program has adapted its strategies based on evolving requirements, focusing on accelerating CIRCM Quick Reaction Capability (QRC) systems to enhance readiness for transitioning to more advanced warning systems like LIMWS.

The CIRCM program's research, development, test, and evaluation activities are supported by substantial resources aimed at advancing A-Kit development and conducting threat and vulnerability analyses across multiple platforms. These efforts include model-based systems engineering and integration testing to ensure robust performance against diverse threat scenarios. By maintaining a focus on technological advancements and system flexibility, CIRCM seeks to provide comprehensive protection for Army aviation assets well into the future.
