Common Missile Warning System
Abstract
The US Army operational requirements concept for Infrared (IR) countermeasure systems is known as the Suite of Integrated Infrared Countermeasures (SIIRCM). SIIRCM is an integrated warning and countermeasure system to enhance aircraft survivability against IR guided threat missile systems. The Common Missile Warning System (CMWS) is a core element of the SIIRCM concept. CMWS is an integrated ultraviolet (UV) missile warning system, and an Improved Countermeasure Dispenser (ICMD) serving as a subsystem to a host aircraft. The CMWS program is a UV missile warning system that cues both flare and laser countermeasures to defeat incoming IR missiles and will provide a limited ability to warn aircrews of 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, hostile missile declaration, and countermeasure employment functions of the system. The CMWS Electronic Control Unit (ECU) receives UV missile detection data from Electro-Optic Missile Sensors (EOMS) and sends a missile alert signal to alert crewmen 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 (CH-47 platform only). In addition, the CMWS ECU receives detections of unguided munitions which it then passes to the aircrew through aural and visual cues. The aircrew then applies the appropriate Tactics Techniques and Procedures (TTPs) to break contact or engage the enemy with on ship ordnance. The CMWS Generation 3 (Gen 3) ECU will meet Tier 1 requirements while retaining a low false alarm rate. The Gen 3 ECU is required to obtain a Full Material 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. CMWS will continue to spend RDT&E funds on the next generation sensor studies, new algorithm updates (Tier 2/3 upgrades) to counter new variants, missiles, and program security initiatives. The sensor studies will evaluate current CMWS technology as compared to the Navy Joint Allied Threat Awareness System (JATAS) program and other service missile warning systems and look at the pros and cons of UV missile warning sensors compared to infrared missile warning sensors for Army aircraft. The study will also examine other technologies to possibly enhance the CMWS UV sensor with either an IR or acoustic adjunct to determine possible cost savings to the United States Government (USG). Justification Fiscal Year (FY)14 Base RDT&E dollars in the amount of $2.910 million supports development engineering of the Threat Analysis Database (TAD) and integration with other ASE systems.
