Common Missile Warning System (CMWS)
Abstract
The CMWS program is a missile warning system that cues both flare and laser-based countermeasures to defeat incoming Inrared (IR)-seeking missiles and will alert aircrews to the presence of certain incoming unguided munitions. The B-Kit consists of the components which perform the missile detection and aircrew notification, unguided munitions detection and aircrew notification, false alarm rejection, and countermeasure employment/cueing functions of the system. The CMWS Electronic Control Unit (ECU) receives ultraviolet (UV) missile detection data from Electro-Optic Missile Sensors (EOMS), which detect UV signals, and sends a missile alert signal to warn aircrews via on-board avionics. Tier 1 threat missiles detected and tracked by the CMWS are subsequently defeated by a combination of missile seeker countermeasures, including decoy flares and IR Laser Jamming (currently Advanced Threat Infrared Countermeasures (ATIRCM)-equipped CH-47 platform only). In addition, the CMWS ECU receives from the EOMS unguided munitions detection data which it also passes to the aircrew through aural and visual alerts. The aircrew then applies the appropriate Tactics, Techniques and Procedures (TTPs) to break contact or engage the enemy with own-ship ordnance. The CMWS Generation 3 (Gen 3) ECU in conjunction with ongoing software development efforts will address outstanding materiel release conditions to achieve a Full Materiel Release (FMR) for CMWS and ensure protection against emerging IR-guided missile threats. The A-Kit for CMWS includes mounting hardware, wiring harnesses, cables, and other components necessary to install and interface the mission kit on host aircraft. The A-Kit ensures the mission kit is functionally and physically operational with a specific host aircraft type. As a part of Phase 2a of the JUONS (SO-0010) program, the Army has now integrated the Department of the Navy Large Aircraft Infrared Countermeasure (DoN LAIRCM) system onto the Apache, Blackhawk, and Chinook platforms. Due to a number of challenges, circumstances, and variables, the Army updated the ATW/CIRCM QRC and LIMWS Directed Requirements (dated 16 November 2018). The updated requirements extend the utilization of ATW DoN LAIRCM on conventional Army aircraft and cancel the need for the ATW/CIRCM QRC system for the conventional Army. (It should be noted that the updated requirement maintains the need for ATW/CIRCM on the Special Operations aircraft.) As a result, the Army will no longer acquire the ATW sensors for use in Phase 3 of the JUONS effort. Instead, the Army will accelerate the procurement of the CIRCM QRC systems for use with the currently fielded Common Missile Warning System (CMWS) in preparation for transition to the Limited Interim Missile Warning System (LIMWS) system when available. Phase 4 Limited Interim Missile Warning System (LIMWS) QRC: Phase 4 LIMWS QRC addressess the HQDA Directed Requirement to provide a greater capability than the current Program of Record (POR), CMWS, to bridge the gap between CMWS and the future POR. Justification: CMWS: FY 2020 Base Research, Development, Test, and Evaluation (RDTE) dollars in the amount of $5.785 million will fund development engineering of Threat and Vulnerability Analysis and Systems Engineering Project Management (SEPM). Phase 3 CIRCM QRC: FY 2020 Overseas Contingency Operations (OCO) RDTE dollars in the amount of $2.220 million will fund System Test & Evaluation (ST&E), technical manual development, and integration efforts to support the Phase 3 Common Infrared Countermeasure Quick Reaction Capability (CIRCM QRC) efforts. Phase 4 Limited Interim Missile Warning System (LIMWS) Quick Reaction Capability (QRC) : FY 2020 Overseas Contingency Operations (OCO) RDTE dollars in the amount $75.200 million are estimated to fund system testing, design for lead platform, and development of follow-on platform designs.
