Joint Tactical Network (JTN)

Mission — Joint Tactical Network (JTN) source

This funding supports Joint and Next Generation Command and Control (NGC2) initiatives to modernize Command and Control (C2) systems. EF5 project: The Joint Enterprise Network Manager (JENM) / Joint Network Management Software for Radio Terminals 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. EX6 project: Waveforms provides the transport technologies and capabilities 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, MANET waveforms, Advanced Networking Waveforms (ANWf), and network enterprise services in support of the Army's network modernization strategy. Waveforms capabilities will remain agile to accommodate emerging warfighter needs by addressing the following: (1) Waveform (WF) analysis and system engineering activities for DoD as Lead Service Activity for Ground/Line of Sight (LoS) Waveforms (currently TSM, WREN, and SINCGARS) in accordance with DoD Instruction 4630.09, Communications Waveform Management and Standardization, 23 November 2020. (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 2025 RDT&E dollars will fund the continued development, integration, and testing of new capabilities and waveform enhancements for SINCGARS, WREN, TSM, and ANWf. As well as fund 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 for future integration and waveform porting efficiencies. The FY 2026 request was reduced by $0.564 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative."

FY 2026 funding will continue radio planner development efforts to design, engineer, integrate and test of planning and management capabilities for the Tactical Radio network in support of the Advanced Networking Waveforms (ANWf). Continued development provides further integration of the Joint Service Networks and Network Management of its emerging systems to enable Soldiers the ability to effectively manage their networks. Radio planner development efforts seek to continue development of joint service waveform support as identified in the Joint Network Management Software for Radio Terminals MOA. Planning applications are deployed on and critically tied to the Ruggedized Application Platform - Tactical Radios (RAP-TR) hardware from Division to the Company level.

Mission — Waveforms source

This funding line is directly aligned to the Army Network Modernization Priority. 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 DoD 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 Defense memo for Enhancing DoD'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 2026 RDT&E dollars (EX6) in the amount of $24.595 million will fund the continued 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.
