Common Infrared Countermeasures (CIRCM) is the U.S. Army’s next-generation, lightweight, laser-based directed infrared countermeasures (DIRCM) system designed to protect rotary-wing, tilt-rotor, and small fixed-wing aircraft from infrared-guided threats, primarily shoulder-fired MANPADS (man-portable air-defense systems) and other heat-seeking missiles.
Key features include:
- Laser-based jamming — Uses advanced, modulated laser pulses (often quantum cascade laser technology) directed precisely at the incoming missile’s seeker head via turreted beam directors to confuse, blind, or decoy the missile’s guidance system, causing it to miss the target.
- Integration — Interfaces with existing or future missile warning systems (e.g., Common Missile Warning System (CMWS), Limited Interim Missile Warning System, or Advanced Threat Warner) for automatic threat detection, tracking, and cueing of the countermeasures.
- Advantages — Lightweight, modular, low-cost, high-reliability design reduces size/weight/power demands compared to legacy systems like ATIRCM; provides rapid, directional protection (seconds to engage) with minimal pilot input.
- Deployment — Developed by Northrop Grumman (program of record); in full-rate production and fielded across U.S. Army platforms including UH-60 Black Hawk, CH-47 Chinook, AH-64 Apache, and special operations variants like the MH-60M and MH-47G operated by the 160th SOAR (Night Stalkers) for enhanced survivability in high-threat, low-level missions.
CIRCM represents fifth-generation IRCM technology, offering superior effectiveness against current and emerging infrared threats while maintaining compatibility across DoD services for broader rotary and fixed-wing applications.
