Aircraft Survivability Development
Abstract
The Aircraft Survivability Development budget line includes Aircraft Survivability Equipment Development (ER7) and Common Missile Warning System (ER8). This budget line also includes funding for Joint Urgent Operational Needs Statement (JUONS) SO-0010 Phase 2a, Headquarters Department of the Army (HQDA) Directed Requirement for the Advanced Threat Warner (ATW) portion of the ATW/ Common Infrared Countermeasures Quick Reaction Capability (ATW/CIRCM QRC), and the next generation missile warning system. ER7: Aircraft Survivability Development. The objective of the Aircraft Survivability Equipment (ASE) Development project is to improve Radio Frequency (RF) ASE for Army aviation. The APR-39 Radar Warning Receiver (RWR) detects, categorizes, and prioritizes RF emitters and provides a visual / aural alert to aircrew members warning them of targeting by RF-guided weapons. The Milestone Decision Authority (MDA) approved Phases 1 and 2 of a 3-phased path forward. Phase 1 serves as an obsolescence / sustainment upgrade to the Processor Line Replaceable Unit (LRU) of the AN/APR-39A(V) RWR implemented to ensure that the currently fielded system remains viable until an affordable improved RF ASE capability can be pursued in Phases 2 and 3. Phase 2 RWR Modernization begins by adopting the United States Navy APR-39D(V)2 system. APR-39D(V)2 will significantly improve the RF threat coverage, automatic detection and identification of threat types, bearing, and lethality. This phase ends upon completion of the Modernized RWR (MRWR) which is an ECP to the APR-39D(V)2 that will implement enhanced hardware upgrades to keep the APR-39D(V)2 technically relevant against agile threats. Phase 3 adds active Electronic Countermeasures (ECM) jamming capability for selected aircraft; Materiel Development Decision (MDD) for this ECM jamming capability phase is not expected until later in the Future Years Defense Program (FYDP). Justification: Fiscal Year (FY) 2019 Base RDT&E funding of $16.163 million supports MRWR development. ER8: Common Missile Warning System (CMWS). The US Army operational requirements concept for Aviation 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 CMWS is a core element of the SIIRCM concept. CMWS is an integrated ultraviolet (UV) missile warning system, with 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-based countermeasures to defeat incoming 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 UV missile detection data from Electro-Optic Missile Sensors (EOMS) 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. Phase 2a DoN LAIRCM (JUONS S0-0010) and Phase 3 ATW/CIRCM QRC Initially, a select number of aircraft in the threat area of responsibility will be outfitted with the Phase 2a Department of the Navy Large Aircraft Infrared Countermeasure (DoN LAIRCM) system. However, this approach came with a Space, Weight and Power - Cooling (SWaP-C) penalty which is being addressed as a follow-on JUONS solution requirement using the Phase 3 Advanced Threat Warner (ATW) / Common Infrared Countermeasure (CIRCM) Quick Reaction Capability (QRC). The intent of the Phase 3 ATW/CIRCM QRC effort is to reduce the SWaP-C associated with the Phase 2a solution. Phase 4 Limited Interim Missile Warning System (LIMWS) QRC The Phase 4 LIMWS QRC effort is a follow-on bridging solution to the JUONS SO-0010 to fill a global capability gap until the Advanced Threat Detection System (ATDS) Program of Record is fielded. The LIMWS QRC effort provides advance missile detection capability to an increased number of aircraft outside of the Phase 2a and Phase 3 efforts areas of responsibility. Justification: CMWS: FY 2019 Base Research, Development, Test, and Evaluation (RDTE) dollars in the amount of $5.802 million fund development engineering of the Threat Analysis Database (TAD), future sensor & algorithm analysis, vulnerability analysis and assessment of technologies (VAAT), and Systems Engineering Process Management (SEPM). Phase 3 Advanced Threat Warner and Common Infrared Countermeasure Quick Reaction Capability (ATW & CIRCM QRC): FY 2019 Overseas Contingency Operations (OCO) RDTE dollars in the amount of $5.110 million fund System Test & Evaluation (ST&E) and tech manual development. Phase 4 Limited Interim Missile Warning System (LIMWS): FY19 Overseas Contingency Operations (OCO) RDTE dollars in the amount of $29.823 million are estimated to fund test of system and design for lead platform and development of follow-on platform designs.
