5th Generation IRCM Technology for Unparalleled Warfighter Protection

Our Common Infrared Countermeasures (CIRCM) solution is a lightweight, highly reliable infrared countermeasure system that is compatible with rotary wing, tiltrotor and small fixed wing aircraft. Within two years of commencing full-rate production, CIRCM has delivered its 500th shipset and achieved over 30,000 operational flight hours across the AH-64, CH-47 and UH-60.

CIRCM utilizes the most advanced laser and pointing technology to protect warfighters against advanced infrared missiles – thus enabling mission success. This affordable solution interfaces with existing aircraft survivability equipment and uses open architecture to support future growth.
