Description
Description — Common Aviation Command and Control System (CAC2S)
Common Aviation Command and Control System (CAC2S) is a Commandant of the Marine Corps (CMC) Force Design (FD) program which provides the Aviation Combat Element (ACE) with the necessary hardware, software, equipment, and facilities to effectively command, control, and coordinate aviation operations. CAC2S accomplishes the missions with a family of systems to support the Marine Air Ground Task Force (MAGTF), Naval forces, Joint Services, and Coalition Forces. CAC2S integrates the functions of aviation command and control (C2) into an interoperable system that supports the core competencies of all Marine Corps warfighting concepts. CAC2S, in conjunction with the Marine Air Command and Control System (MACCS) organic sensors, AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR), and the weapon system Composite Tracking Network (CTN) provides enhanced air control, improved situational awareness, sensor integration, full Tactical Data Link integration, airspace and battle planning and command functionality, as well as sensor netting integration (CTN). CAC2S, with these organic MACCS programs, support the tenets of Expeditionary Maneuver Warfare and foster joint interoperability. CAC2S Increment I replaced legacy aviation command and control systems in the following Marine aviation agencies: Direct Air Support Center (DASC), Tactical Air Command Center (TACC), and Tactical Air Operations Center (TAOC). CAC2S employs an evolutionary acquisition strategy utilizing an incremental and phased approach for development and fielding of the CAC2S. The Capability Production Document (CPD) identifies two increments to achieve the full requirements of CAC2S. The current acquisition strategy addresses Increment I of the CAC2S acquisition process and focuses on the requirements that will modernize the assault and air support, air defense and control, and Aviation Combat Element (ACE) battle management capabilities of the Marine Air Command and Control System (MACCS). Increment I of the CAC2S has been accomplished through a two phased approach: Phase 1 addressed the requirements to establish the baseline CAC2S capabilities for the MACCS and improved Air Command and Control (AC2) performance and effectiveness; Phase 2 addresses the requirements for remaining ACE Battle Management Command & Control (BMC2) requirements. CAC2S has successfully completed the fielding of its AN/TSQ-197 Air Command and Control System (AC2S) full rate production Full Deployment Units (FDUs) in FY 2020. The AN/TSQ-197 AC2S requires a technology refresh every 5 years to replace all obsolete hardware and software with new military-grade commercial-off-the-shelf (COTS) information technology (IT) configuration items to maintain operational performance and remain aligned with industry standard and service enterprise computing environment directives. In line with Force Design, CAC2S began the development and production of the Small Form Factor (SFF) variant in FY 2022. The CAC2S SFF variant is a forward deployed small, scalable, survivable aviation C2 nodes capable of performing control of aircraft and missiles necessary for integration and defeat of dynamic targets performed by the Marine Air- Ground Task Force (MAGTF), naval, joint, and national technical enabling capabilities. The procurement of a CAC2S Small Form Factor Variant is in response to a Deliberate Universal Needs Statement for the development of a viable capability to close significant C2 gaps associated with the Expeditionary Advance Base Operations (EABO) concept and National Defense Strategy-aligned future technology investments. Like the current AN/TSQ-197 AC2S, the SFF variant consists of two subsystems: the Data Module and Communications Module. SFF consists of commercial-off-the-shelf (COTS) hardware components which will be assembled and delivered by the Naval Surface Warfare Center - Crane Division (NSWC-Crane). The SFF is required to meet the needs of the Expeditionary Advance Base Operations (EABO) concept, which is an amphibious forward operating unit that will secure, sustain, and maintain warfighters and their weapons systems on a more amorphous and difficult-to-target forward-basing infrastructure. The SFF variant will possess the same Tactical System, Data Link, and interface capabilities as the CAC2S Increment 1 system with the added benefits of being rapidly deployable, emitting at a lower signature, and reduced size and weight. In addition, the SFF's versatility will be a key enabling capability to support the task organization of the Marine Littoral Regiments (MLRs) as it meets the needs of US Marine Corps EABO. CAC2S will produce and field 42 systems. In accordance with the Deputy Secretary of Defense memorandum for record (MFR) 25 October 2019, CAC2S is mandated to support the modernization of Link 16 across all Services. The joint service solution is to integrate the Multifunctional Information Distribution System Joint Tactical Radio Systems (MIDS JTRS) four-channel radio. It runs the Link 16 waveform, Link 16 is the Joint Force's primary Tactical Data Link, and up to three additional communication protocols, including the Airborne Networking Waveform (ANW). The system enhances operational effectiveness without consuming more space, weight or power. CAC2S will support the system integration of its AN/TSQ-297 and AN/MRQ-13 Communications Subsystem onto the M1279 Joint Light Tactical Vehicle (JLTV) and the M1289 trailer. CAC2S will be provided JLTVs in FY 2025 and begin the procurement of material for engineering change proposals (ECPs) to integrate its systems onto its replacement prime mover.
Justification
Justification — Common Aviation Command and Control System (CAC2S)
FY 2026 Base Appropriation Request $68.589M: CAC2S: FY 2026 funding supports the procurement of 9 CAC2S Small Form Factor variant systems, associated spares, and fielding of systems. Additionally, funding will support the procurement of components for engineering change proposals to enable CAC2S to integrate its AN/TSQ-297 system and AN/MRQ-13 Communications Subsystem on to the JLTV and trailer as well as Link-16 Modernization and Prime Mover Integration. The Small Form Factor Decision Package supports capacity to support force design concepts for near peer threats through the distributed C2 of aircraft and missiles, distribution of sensor data (G/ATOR), Anti-Air Warfare, and Surface Warfare. SFF also supports Link-16, 5th generation fighter integration, Navy Marine Expeditionary Ship Interdiction System fires integration, advanced targeting/cueing, and airspace management. The Prime Mover Integration Decision Package supports the Service move from High Mobility Multipurpose Wheeled Vehicle (HMMWV) to JLTV as prime mover. Decrease from FY 2025 to FY 2026 is primarily due to procuring less quantities of the AN/TSQ-297 Small Form Factor systems and associated support.
