The Common Missile Warning System (CMWS) and Advanced Threat Infrared Countermeasures (ATIRCM) system integrates defensive infrared (IR) countermeasures capabilities into existing, current-generation aircraft to engage and defeat IR-guided missile threats.
The Army operational requirements concept for IR countermeasures systems is the Suite of Integrated Infrared Countermeasures (SIIRCM). The CMWS and ATIRCM programs form the core element of SIIRCM. CMWS can function as a stand-alone system with the capability to detect missiles and provide audible and visual warnings to pilots. When installed with the Advanced IRCM Munitions and improved countermeasure dispensers, it activates expendables to decoy and defeat IR-guided missiles.
ATIRCM protects crews and aircraft from advanced threat Man Portable Air Defense Systems (MANPADS) until CIRCM is fielded.
The CIRCM program of record is entering Engineering & Manufacturing Development (EMD) and is being developed to replace ATIRCM. CIRCM will be lighter weight and more reliable, and have more affordable lifecycle costs. It is also designed to operate with CMWS and future missile warning systems to provide protection for rotary-wing, tiltrotor and small fixed-wing aircraft across DoD.
BENEFIT TO THE WARFIGHTER
MANPADS are proliferated worldwide and pose a strategic threat to all DoD rotary-wing and fixed-wing aircraft. Threat detection sensors are the first step in the detection-and-defeat engagement sequence. Improving sensor capability and exploiting new sensor technology translates into seeing the threat sooner and at greater distances, buying more time for the warfighter to successfully engage with an effective countermeasure solution. The combination of CIRCM and flares helps provide a tiered defense for DoD aircraft.
