Joint Tactical Network (JTN)

This funding supports the Army's Next Generation Command and Control (NGC2) initiative to modernize Command and Control (C2) systems, Transport Layer. This project provides the transport technologies necessary to support the overall connectivity of the Unified Network. Waveforms technology assessments, integration, and configuration management enable seamless updates and fluid communication between echelons of the Unified Network. Waveforms delivers, maintains, and upgrades portable, interoperable, Mobile Ad-hoc Networking (MANET) waveforms, Advanced Networking Waveforms (ANWf), network management and monitoring protocols and standards, and network enterprise services in support of the ARMY network modernization strategy. These waveforms and services are deployed by technical insertion into production of, and field upgrades to, existing tactical radios. Waveforms will remain agile to accommodate emerging warfighter needs by addressing the following: 1) Waveform (WF) analysis and system engineering activities for DoW as Lead Service Activity for Ground/Line of Sight (LoS) Waveforms (currently TSM), Warrior Robust Enhanced Network (WREN), and Single Channel Ground and Airborne Radio System (SINCGARS)) in accordance with (IAW) Deputy Secretary of War memo for Enhancing DoW's Joint Tactical Networks and Datalink Modernization, 29 March 2019 2) Development and/or integration efforts of Broadcast Waveforms (i.e. SINCGARS, WREN, ANWf) and Radio Services (i.e. enterprise Over The Air Management (eOTAM)) in support of Army Network modernization, and agile mission support initiatives 3) Viability assessments of ANWf in support of the Integrated Tactical Network (ITN) and future capability sets to ensure waveform performance in advance of formal ITN experimentation and fielding activities FY 2027 funding will continue development, integration, and testing of new capabilities and waveform enhancements for SINCGARS, WREN, TSM, and ANWf. Additionally, funding supports the next generation Government developed waveforms and Radio Service applications, system and architectural engineering for ANWf radio communications technologies, post deployment software support for fielded versions of the waveforms and radio services, program management support, and examine modular and open system architectures (MOSA) to make future integration and waveform porting more efficient.

This funding supports Joint and Next Generation Command and Control (NGC2) initiatives to modernize Command and Control (C2) systems. The Joint Enterprise Network Manager (JENM) / Joint Network Management Software for Radio Terminals (JNMSRT) provides a single, converged network management tool allowing the Warfighter to plan, configure, load, and manage the Joint Services' Tactical Radios and their networks in the field - a capability not available in legacy planning systems. Funding supports the full suite of Software defined radios across the services, enabling them to utilize Mobile Ad Hoc Networking (MANET) and other waveforms to include: Mobile User Objective System (MUOS), TrellisWare Scalable Manet (TSM), Warrior Robust Enhanced Network (WREN), Warrior Robust Enhanced Network-Narrowband (WREN-NB), Demand Assigned Multiple Access (DAMA) Satellite Communications (SATCOM), Integrated Waveform (IW), VHF-UHF Line Of Sight (VULOS), Second Generation Antijam Tactical UHF Radio for NATO (SATURN) and Single Channel Ground and Airborne Radio System (SINCGARS) waveform. The Network Management Software provides the Commander the ability to quickly reconfigure critical networks and enhances the S6's ability to conduct Course of Action (COA) Analysis and the Military Decision-Making Process (MDMP), providing commanders critical information regarding their ability to communicate. FY 2027 RDT&E funds will be allocated to the continued development, integration, and testing of advanced capabilities supporting waveform enhancements for tactical communications systems such as SINCGARS, WREN, TSM, and ANWf. Key initiatives will focus on next-generation waveforms, creating innovative radio service applications, and performing detailed system and architectural engineering. These efforts will leverage a Modular Open Systems Approach (MOSA) to ensure future porting efficiencies and adaptability. In alignment with the JNMSRT Memorandum of Agreement, FY2027 RDT&E funding will also continue to support the ongoing design, engineering, and testing of network management capabilities for the Tactical Radio network. This will ensure full interoperability across Joint Service Networks and emerging systems. The primary deliverable will be mission-critical planning applications designed for modular, cross-platform deployment.
