Develop and field world-class aircraft survivability systems that maximize the survivability of Army aircraft against a continually evolving threat without degrading combat mission effectiveness.
Detects missile launches/flights, protects aircraft from infrared (IR) guided missiles, and provides threat awareness and IR countermeasures using an airborne self-protection system.
ATIRCM provides warning of missile approach using the AN/AAR-57 Common Missile Warning System (CMWS), which detects the missile, rejects false alarms, and cues the onboard infrared jamming system’s jam head to the missile’s location. When the jam head finds the missile with its IR tracking system, it emits a high-energy infrared beam to defeat the missile’s infrared seeker.
Defeat man-portable air defense systems (MANPADS) threats thereby increasing aircraft survivability
CIRCM is the next generation lightweight, laser-based infrared countermeasure component that will interface with both the Army’s Common Missile Warning System (CMWS) and future missile warning systems (MWS) to defeat current and emerging missile threats to target rotary-wing, tilt-rotor and small fixed-wing aircraft across the DoD. CIRCM receives hand-off from the MWS, and employs a pointing and tracking system to track incoming missiles. CIRCM is utilizing Open Systems Architecture which allows flexibility with software and hardware refreshes to keep pace with future threats.
CIRCM is the lighter weight system analogous to the Advanced Threat Infrared Countermeasures (ATIRCM) system which is only installed on CH-47F aircraft.
The CIRCM system will operate with the Army’s MWS (CMWS). The “Common” refers to the intent that the system is designed in such a way that it can be integrated with other-Service platforms’ MWS and be required to communicate with the MWS using a standard Interface Control Document.
The CIRCM program continues EMD activities and is executing within the parameters outlined in the APB.
On 14 SEP 18, the AAE approved the CIRCM MS C decision. Now, the CIRCM program is initiating Low Rate Initial Production in preparation for the Initial Operational Test and Evaluation in FY19. The CIRCM system is also being accelerated to field in support of Quick Reaction Capability (QRC) requirements. A limited number of CIRCM systems will be integrated with the Advanced Threat Warner (ATW) missile warning system to meet critical size, weight, and power requirements associated with current urgent fielding needs.
Airborne self-protection system which detects missile launch/flight and protects aircraft from Infrared (IR) guided missiles and unguided munitions. Provides threat awareness and data required to deploy IR countermeasures.
An integrated IR countermeasures suite utilizing five sensors to display accurate threat location and dispense decoys/countermeasures, detects missile launch and flight of infrared guided threat missiles and unguided munitions to protect Army aircraft. CMWS provides passive missile warning and hostile fire indicators while operating independently or as a component of the ATIRCM and CIRCM systems. Provides detection of unguided threats and situational awareness to aircrew with visual and aural cueing. Protects aircraft by deploying flares and/or by cueing laser-based countermeasure systems. Consists of five Missile Sensors mounted to the surface of the aircraft, an Electronic Control Unit (ECU), a reprogrammable User Data Module, a Sequencer and Improved Countermeasure (flare) Dispensers.
CMWS remains a highly effective and reliable system, having amassed over 3 million combat hours. CMWS reliability has been independently scored as exceeding its threshold requirement by 800%. Most importantly, the US Army has not lost an aircraft or crew to a Man-Portable Air-Defense System since 2007.
