C2P RDT&E initiatives include: 1) C2P Technology Refresh (TR) cybersecurity updates and C2P v3.13 software certification; and 2) C2P Modernization capability development and Link 22 integration. Link Monitoring and Management Tool (LMMT): LMMT is the Military's premier solution providing Joint Interface Control Officers (JICOs) and Maritime Operations Centers (MOCs) with effective monitoring and performance management of TDL networks in designated Areas of Responsibility (AORs). LMMT also allows Marime Component Commanders to Fight from the MOC and perform MOC in the Middle functions in support of JADC2 and BMD missions. LMMT RDT&E initiatives will deliver an improved commercial off-shelf hardware design, providing gateway functions for multiple TDL interfaces, routing and display of TDL data to include Link 16, Joint Range Extension (JRE) and Link 22. (3020) The Multifunctional Information Distribution System (MIDS) is the most widely fielded family of Tactical Data Link radio terminals in the world. The MIDS program office is the Performing Activity for the Navy (Lead Service for Department of Defense (DOD)), Link 16 capability and consists of two (2) product lines, MIDS Low Volume Terminal (LVT) (legacy hardware defined radio) and MIDS Joint Tactical Radio System (JTRS) (software defined radio). MIDS-LVT effort is a cooperative development program between France, Germany, Italy, Spain, and the United States with United States joint service participation (Navy, Army, Air Force), and has provided over 12,000 terminals to more than 50 Nations providing interoperability with North Atlantic Treaty Organization (NATO) and coalition partners. The Department of Defense (DoD) established the program to design, develop, and deliver low volume, lightweight tactical information system terminals for U.S. and allied fighter aircraft, bombers, helicopters, ships, and ground sites. MIDS-LVT significantly increases force effectiveness and minimizes hostile actions and friend-on-friend engagements. MIDS-LVT Block Upgrade 2 was executed as an Engineering Change Proposal (ECP) and provides the critical upgrades to the MIDS-LVT Terminal to enable U.S., Coalition and International partners' ability to meet the National Security Agency (NSA) mandated timelines for Cryptographic Modernization (CM) and the National Telecommunications and Information Agency (NTIA) and Federal Aviation Agency (FAA) mandated timelines for Frequency Remapping (FR). Multifunctional Information Distribution System (MIDS) Joint Tactical Radio System (JTRS), designed as a Pre-Planned Product Improvement (P3I) and executed as an Engineering Change Proposal (ECP) to the production MIDS Low Volume Terminal (LVT) configuration, and is fully compatible with MIDS-LVT. The MIDS JTRS Core Terminal achieved Full Production and Fielding (FP&F) in March 2012. It facilitated the JTRS incremental approach for fielding advanced JTRS transformational networking capability and transformed the MIDS-LVT into a 4-channel, Software Communications Architecture (SCA) compliant, Joint Tactical Radio. A form-fit-function replacement to MIDS-LVT, MIDS JTRS also adds three programmable 2 Megahertz (MHz) to 2 Gigahertz (GHz) channels capable of hosting the JTRS legacy and networking waveforms. In addition to Link 16, Tactical Air Navigation (TACAN), and voice functionality found in MIDS-LVT, MIDS JTRS has four channels and adds capabilities such as Link 16 Enhanced Throughput (ET), Link 16 FR, software programmability, CM, and Four Net Concurrent Multi-Netting with Concurrent Contention Receive (CMN-4). MIDS JTRS Tactical Targeting Network Technology (TTNT), is a block upgrade to the MIDS JTRS CMN-4 Terminal providing an Internet Protocol-based networking capability on tactical aircraft. TTNT is a low latency, high throughput waveform that has the capability to support data exchange between fast-moving tactical aircraft, weapons, and unmanned aircraft, in addition to air, land, and sea-based command and control nodes, in a variety of air-to-air and air-to-ground missions including time sensitive targeting, air warfare, close air support, non-traditional ISR, and anti-surface warfare. TTNT and MIDS JTRS CMN-4 are critical Tactical Data Link capabilities and directly supports Naval Integrated Fire Control (NIFC) capability requirements. These capabilities provide Joint Airborne Network-Tactical Edge functionality to run advanced mission applications in a cross-platform/cross-domain tactical network enterprise. The FY 2026 Budget begins Electromagnetic Compatibility Features (EMCF) test automation and regression testing for MIDS JTRS/TTNT and MIDS-LVT variants and also completes the Integrated Software Build 9.2, Block Cycle 2 for fleet release of various updated capabilities (specific capabilities classified). The FY 2026 budget also reinstates funding for the TACAIR RIL (Reference Implentation Laboratory). (3078) Digital Modular Radio (DMR) with Integrated Waveform (IW) and Mobile User Objective System (MUOS) capable hardware is the Navy's technical solution for the IW/MUOS requirement. The compact, multi-channel DMR provides 3G, Wideband Code Division Multiple Access (WCDMA) technology, for high speed/capacity voice and data satellite communications. DMR radios currently operate aboard U.S. Navy surface and subsurface vessels, fixed-sites and other Department of Defense (DoD) communication platforms using frequencies ranging from 2 MHz to 2 GHz. Certified to pass secure voice and data at Multiple Independent Levels of Security (MILS) over High Frequency (HF), Very High Frequency (VHF), Ultra High Frequency (UHF), and Satellite Communications (SATCOM) channels, the DMR system was developed to the U.S. Navy's specifications and meets all the stringent environmental, Electromagnetic Interference (EMI) and performance requirements for use in the U.S. Fleet. This system is formally specified by both Fleet Commanders as a threshold capability, for global maritime command control and communications in a Distributed Maritime Environment, to execute current warfighting plans and is required for National Command and Control capability. This program is for continued development/integration of the IW and MUOS waveforms into the DMR in accordance with Military Standards 188-181,2,3. Additionally, the enhancements of High Frequency Distribution Amplifier Group (HFDAG) and, HF Automated Link Establishment (ALE) and Second-Generation Anti-Jam Tactical UHF Radio for NATO (SATURN) will also be developed/integrated into the DMR. HFDAG is a follow-on HF solution to fulfill transmit and receive HF communication capability with various modes of operation, such as ALE, for Navy platforms. HFDAG will utilize the existing DMR as the exciter/receiver. Generation 3 (GEN 3) HF ALE/HF wideband provides Navy users with improved HF communications, increased transmission rates from radio to radio, and serves as a supplement to SATCOM when SATCOM networks are overloaded or unavailable. SATURN is the follow-on HAVEQUICK II anti-jamming solution in accordance with NATO Standardization Agreement 4372. SATURN capability will counter adversaries' jamming efforts and ensure Navy's Assured Command and Control UHF communications operational end-to-end capability as well as enhance interoperability within/between DMR users and with Allied/Coalition partners. IW uses a Time Division Multiple Access (TDMA) communication system in an attempt to improve satellite bandwidth utilization over legacy SATCOM waveforms. This enables demand assigned services on UHF SATCOM networks to support new applications that require better performance and higher channel throughput. The MUOS waveform will enable MUOS satellites to provide worldwide communication satellite coverage for DoD requirements. MUOS will provide functionality comparable to commercial mobile phone systems. In FY 2026, the program will complete MUOS 3.2 and SATURN development integration and test efforts with the DMR. DMR will begin the design, testing, and integration of a follow-on tactical communication solution that will deliver critical cryptographic compliant waveforms to the fleet. (3341) Network Tactical Common Data Link (NTCDL) provides the ability to transmit/receive real-time Intelligence, Surveillance, and Reconnaissance (ISR) data simultaneously from multiple sources (surface, airborne, sub-surface, man-portable), and exchange command and control information (voice, data, imagery, and Full Motion Video) across dissimilar joint, service, coalition, and civil networks. NTCDL provides warfighters with the capability to support multiple, simultaneous, networked operations with currently fielded Common Data Link (CDL)-equipped air platforms (e.g. MH-60R), in addition to next generation manned and unmanned platforms (e.g., P-8, Triton, MQ-25 (Stingray), small tactical unmanned aircraft systems (STUAS) and Fire Scout). NTCDL is an incremental capability (surface, airborne, sub-surface, and man-portable) providing modular, scalable, multiple-link networked communications. NTCDL benefits the fleet by providing a horizon extension for line-of-sight sensor systems for use in time-critical strike missions and supports tasking, collection, processing, exploitation, and dissemination (TCPED) via its ISR networking capability. NTCDL supports Resilient Command and Control (RC2) through its relay capability, and supports TCPED through its ISR networking capability. FY 2026 request is for NTCDL to continue Capability Enhancement Development including Bandwidth Efficient Common Datalink (BE-CDL) waveform implementation. (4011) The Navy Expeditionary C4I project supports the Navy Expeditionary Combat Command (NECC) mission to detect, deter or interdict potential threats to DoN assets using agile, modular and scalable technology. NECC units have a number of current and future Command, Control, Communications, Computers & Intelligence (C4I) technological requirements for Tactical/Command Operations Center, tactical vehicles, combatant craft, and dismounted personnel. NECC operations require units to maintain effective command and control, develop and display a common tactical picture, and share intelligence and current operational information with higher headquarters, subordinate units, joint forces and coalition allies. Small, Medium, and Large Scale Communication Systems (LSCS) are the C4I hub for the NECC; Expeditionary Deployable Node (EDN) is the converged LSCS baseline. Future C4I research and development include enhanced information transport, network cyber security posture, assured communications in denied environments along with agility and mobility. Funding is required for testing and evaluation of cyber security issues associated with obsolescence of network items and if not addressed will impact the ability of the Program Office to maintain system accreditation under Risk Management Framework (RMF) revoking multiple LSCS assets authority to connectivity on the Department of Defense Information Network (DoDIN). Efforts are in alignment with NECC's strategic Expeditionary Warfare Improvement Program (EXWIP) Integrated Priority Capability List (IPCL) priorities and maintain alignment with greater DoD initiatives, such as Joint Information Environment (JIE), Mission Partner Environment (MPE) in order to maintain interoperability and drive down DoN enterprise costs. FY26 request is for the development of an implementation strategy for the multiyear cloud adoption strategy to migrate Joint Expeditionary Cloud Services assess feasibility of migrating Tactical Entry Point (TEP) services to a cloud and/or carrier-neutral facility (CNF) in the DoD Multi-Cloud (Public) architecture.

Mission — NAVSTAR GPS Equipment source

The FY 2026 funding decrease of $13.689M from FY 2025 to FY 2026 is due to completion of LN-251M development as well as completion of the feasibility study for using a Janus Software Design Receiver (SDR) as a GPS Receiver Card and continue to study opportunities to incorporate improvements into GPS receivers. Navigation Satellite Timing & Ranging (NAVSTAR) GPS project (0921) encompasses the Navy's efforts to pace the growing threat to GPS Navigation through the fielding of new GPS receivers, Anti-Jam (AJ) Antennas, and Assured Positioning Navigation and Timing (A-PNT) technologies across all Navy platform types. NAVSTAR GPS is a group of A-PNT systems that provides authorized users with secure, worldwide, all weather, three dimensional position, velocity, and precise time data. NAVSTAR GPS provides A-PNT capability to Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance (C4ISR) and combat systems in standalone and networked architectures throughout air and maritime domains. This project is comprised of four distinct efforts: Sea Navigation Warfare (NAVWAR), GPNTS, Air NAVWAR and GPS Modernization. Sea NAVWAR provides AJ antennas and Global Positioning System (GPS) - Based Positioning, Navigation and Timing (PNT) Service (GPNTS) provides GPS Receivers and A-PNT technology to surface platforms, and Air NAVWAR provides AJ antennas and GPS Modernization provides GPS receivers to air platforms. Research, Development, Testing and Evaluation (RDT&E) funding is used to perform all the non-recurring GPS related development, integration, and testing efforts for surface ships and aircraft in support of NAVSTAR GPS. The Air and Sea NAVWAR programs provide continued access to GPS information in a denied or impeded electronic environment. Development efforts for both programs provide improvements to various platform type antennas and ensure compatibility with the new GPS M-Code signal. The Air NAVWAR program continues integration efforts using GPS Antenna System (GAS-1), Advanced Digital Antenna Production (ADAP), and other AJ antennas on air platforms while investigating smaller AJ antennas for space constrained platforms and aircraft with unique requirements. The Sea NAVWAR program integrates AJ antennas onto surface and subsurface platforms. The Sea NAVWAR program will continue to research the viability and development of enhanced AJ techniques and technologies. The GPNTS system is the primary and modernized A-PNT system for the surface Navy to ensure reliable PNT capability and interoperability insertion into GPS receivers and associated C4ISR and Combat Systems in a denied environment. GPNTS pairs with AJ antennas and provides precise A-PNT data required for combat, weapons, command, control, communications, navigation, and other systems, as well as providing the time synchronization critical for network environments. GPNTS will back fit current GPS/PNT systems as well as serve as a forward fit for new platforms. GPNTS is an Open Architecture (OA) development, enabling rapid software and hardware based capability improvements to be inserted without a requirement for single-source contracting. GPNTS will host the United States Space Force (USSF) GPS Directorate-developed Military GPS User Equipment (MGUE) card, allowing access to the new GPS M-Code signal. GPNTS will provide more robust and secure GPS/PNT capabilities than is currently in the Fleet. The system will provide the capability to migrate non-real time GPS data toward a Common Computing Environment (CCE) and provide a path for the integration of advanced navigation systems and sensors. GPNTS provides A-PNT capability to C4ISR and Combat Systems in standalone and networked architectures throughout maritime domains. Global Position System (GPS) Modernization integrates and tests the Military GPS User Equipment (MGUE) being developed by the United States Space Force (USSF) and United States Air Force (USAF) Life Cycle Material Command into Naval aircraft to provide improved access to GPS signals in challenged and jammed environments. This project will provide central coordination and management of priorities and funding of multiple parallel efforts to integrate different MGUE into various type/model/series aircraft across multiple platform program offices. Due to the diversity of Naval aircraft, each platform will require unique platform integration and testing that includes software updates to avionics and mission computers as well as modifications to the airframe based on Size, Weight, Power and Cost (SWaP-C) requirements. GPS Modernization delivers increased GPS Anti-Jam (AJ) protection through modernized GPS receivers that will utilize the new Military Code (M-Code) GPS Signal in Space, incorporate enhanced cryptology, enable blue force GPS electronic attack, deliver greater position and time accuracy, and provide improved protection against signal spoofing as compared to legacy receivers. This effort supports Navy compliance with Public Law 111-383 which prohibits using funds after FY2017 to purchase GPS User Equipment unless it is capable of receiving the GPS M-Code signal.

Mission — Congressional Adds source

C370: This project develops and improves the Navy's Tactical Data Link (TDL) systems, and it includes the Advanced Tactical Data Link Systems (ATDLS) Integration Programs, specifically Link 16 Network, Command and Control Processor (C2P) and Link Monitoring and Management Tool (LMMT). ATDLS Integration Program develops new and improved capabilities for Navy TDL users. The ATDLS Integration Programs perform technical analyses and engineering efforts associated with implementation of new technology to enable rapid introduction of new products and technology, prevent obsolescence, and end of support issues. The programs insert new technology enhancements via incremental software & hardware upgrades and deliver in annual build release. The Navy Link 16 Network Increment II requires Enhanced Throughput (ET), Concurrent Multi-Netting (CMN), Current Contention Receive (CCR), and Tactical Targeting Networking Technology (TTNT), and tech refresh with Block Upgrade 3 (BU3). C2P is a critical component of the shipboard combat system enabling tactical data link integration with the combat systems. C2P is a critical component of the Aegis Ballistic Missile Defense (BMD) architecture. C2P Technology Refresh (TR) will modernize obsolete C2P system hardware components and improve C2P system cyber security posture. C2P Modernization (MOD) is a service life extension effort required to sustain C2P system viability and significantly improve its cyber resiliency. C2P MOD modernizes the legacy C2P system software to enable improved cyber resiliency, improved system operational availability and the ability to run in multiple hardware environments. Link 22 development and integration into the C2P allows for improved maritime tactical data link operations with coalition forces. LMMT will upgrade commercial off-the-shelf hardware and modernize software operating systems. LMMT will perform monitoring and management of all TDL and provide information in support of the Integrated Air & Missile Defense (IAMD) and Ballistic Missile Defense (BMD) missions. Command and Control Processor (C2P): The two Research Development Test & Evaluation (RDT&E) initiatives are 1) C2P Technology Refresh (TR) cyber security update and 2) C2P Modernization which now includes Link 22 integration. C2P TR cyber security update is a new initiative driven by recently discovered cyber security risk to the C2P system in support of the BMD mission. The C2P TR Cyber security update is planned to support acceleration on all AEGIS BMD ships. C2P Modernization funds the transition of the C2Ps legacy Compiler Monitor System (CMS-2Y) software code (old Navy unique computer programming language from the 1980s) to a modern software language. Transition to a modern software language is required to sustain the system software, to adequately address growing cybersecurity and operational availability challenges, and to enable more affordable transition to new hardware processing components as a result of commercial of the shelf processor obsolescence. Link 22, which was previously planned for fielding in the C2P TR architecture, has been delayed until the fielding of C2P Modernization. This was based on prioritizing existing resources to address the emergent cyber security risk that has resulted in the C2P TR cybersecurity update plan. Link 22 is a modernized replacement for Link 11, providing beyond line of site (BLOS) tactical data communications using high frequency (HF) radios. Link 16 Network Increment II: These Link 16 efforts are in support of Joint Chiefs of Staff Joint Requirements Oversight Council Memorandum (JROCM) 075-17 for installation and integration of Multifunctional Information Distribution System (MIDS) Joint Tactical Radio System (JTRS) (MIDS J) terminals into the Navy shipboard environment. These include: (1) the modification the MIDS on Ship (MOS) cabinet as a MOS MIDS JTRS Engineering Charge Proposal (MMJE), and via the MOS Modernization (MOS Mod) cabinet systems for ships with the legacy JTIDS systems; (2) JROCM 097-20 and the JROC-validated MIDS JTRS Capability Production Document (CPD) 10 February 2011 which provided direction for Crypto Modernization (CM), Frequency Remapping (FR), Enhanced Throughput (ET), CMN, CCR, and TTNT. These systems are interfaced to shore sites and ships via C2P Technology Refresh (Tech Refresh) version 3.13 software, and to the combat systems with C2P via Integrated Shipboard Network Systems (ISNS) for TTNT; (3) Developmental Testing (DT) / Operational Testing (OT) of Navy platform JTRS modifications and the integration of TTNT; (4) provide product improvement for continued production capability MOS and MOS Mod, with extensibility of new Tactical Data Link capabilities of shipboard Link 16 terminals; and (5) the development and qualification to replace shipboard Link 16 4400 antenna with the 4557 antenna. Link Monitoring and Management Tool (LMMT) is a system delivered on commercial off-the-shelf hardware (HW) providing gateway functions for multiple Tactical Data Link (TDL) interface, routing and display of TDL data to include Link 16, Joint Range Extension (JRE) and Link 22. LMMT is also capable of performing TDL network monitoring and management, data forwarding between the TDLs and providing tactical data to the Integrated Air & Missile Defense (IAMD), Ballistic Missile Defense (BMD) network, and Global Command and Control System (GCCS) for establishing the common operational picture. LMMT requirements will be incrementally developed and delivered in capability drops via the Joint Capabilities Integration Development System (JCIDS) IT Box approach. C371: This project will conduct a study and design effort to construct a model for a modular, open architecture satellite terminal system which could augment and replace portions of the Navy Multiband Terminal (NMT). Government engineering agencies will co-lead efforts alongside industry experts to study and propose a COTS-based system which could meet portions of NMT's MILSATCOM capabilities. The goal is to create a scalable, reliable, and cost effective design which could meet many of NMT's Key Performance Parameters (KPP)s by providing resilient and diverse capabilities, across multiple orbits and bands, ensuring an ecosystem of cross-threaded SATCOM capabilities spanning high Technology Readiness Level (TRL) Wideband and Commercial technologies. Phase 1 of the effort will be a study which will propose a general design. Phase 2 will produce a testable system which will emphasize standard form factors and industry standard open interfaces in accordance with SATCOM industry standards.

FY2026 Justification (Link 16): No funding programmed in FY2026. Program testing and development requirements concluded in FY2025 to include A(v)6 initiatives, TTNT Terminal Controller SW development, and integration testing efforts of MIDS JTRS Block Upgrades 3 (BU3), TTNT, and the associated Terminal Controller. Command and Control Processor (C2P): C2P is the only shipboard solution that enables bi-directional exchange of tactical information across multiple TDLs within the joint operations areas. C2P processes and exchanges Link 11, Link 16, Satellite TDL J, and Joint Range Extension Applications Protocol (JREAP) tactical data among the US, North Atlantic Treaty Organization (NATO), and allied nation military platforms enabling the vital joint TDL interface. Additionally, C2P provides data translation services, acts as a single interface between host combat system and TDL networks, and forwards tactical data between platforms operating at extended ranges. C2P enables surface platforms capability to conduct Ballistic Missile Defense BMD Launch-on-Remote/Engage-on-Remote and Autonomous Vehicle missions. C2P RDT&E initiatives include: 1) C2P Technology Refresh (TR) cybersecurity updates and C2P v3.13 software certification; and 2) C2P Modernization (Mod) capability development and Link 22 integration. C2P TR certification efforts enable Link 16 and TTNT throughput enhancements onboard surface units per JROCM 097-20, equipping warfighters with faster tactical network speed and improved capacity. C2P TR cybersecurity updates fix a recently discovered cybersecurity risk to the C2P system onboard BDM assets, endangering fire control loop effectiveness. C2P Mod integrates Link 22 capability, improving interoperability with coalition partners by delivering high frequency (HF) beyond line of site (BLOS) tactical data communications. C2P Mod also transitions C2P software code from Compiler Monitor System (CMS-2Y) software code (old Navy unique computer programming language from the 1980s) to a modern production software language. Transition to a modern software language enables agile DevSecOps software support for rapid capability upgrades, enabling continuous kill chain improvements and regular cyber hardening enhancements. Additionally, C2P Mod design is transitioning from a legacy hardware build to a more commercial-off-the-shelf build, improving operational availability and reducing future obsolescence costs. FY2026 Justification (C2P): Implementing the development initiatives above will improve C2P cybersecurity hygiene, provide more reliable hardware, and create an architecture that is more cost effective for future upgrades and corrections to latent defects. Commence C2P Mod combat system integration testing. Continue C2P Modernization (Mod) Pre-Planned Product Improvement Program (P3I) design and development. Link Monitoring and Management Tool (LMMT): LMMT is the Military's premier solution providing Joint Interface Control Officers (JICOs) and Maritime Operations Centers (MOCs) with effective monitoring and performance management of TDL networks in designated Areas of Responsibility (AORs). LMMT also allows Marime Component Commanders to Fight from the MOC and perform MOC in the Middle functions in support of JADC2 and BMD missions. LMMT RDT&E initiatives deliver an improved commercial off-shelf hardware design, providing gateway functions for multiple TDL interfaces, routing and display of TDL data to include Link 16, Joint Range Extension (JRE) and Link 22. LMMT initiatives also deliver improved data forwarding between separate TDL networks, Integrated Air & Missile Defense (IAMD), BMD network, Global Command and Control System (GCCS) establishing a common operational picture. LMMT requirements will be incrementally developed and delivered in capability drops via the Joint Capabilities Integration Development System (JCIDS) IT Box approach. FY2026 Justification (LMMT): Testing and engineering support wrap up for the integration of TTNT and Link 16 Concurrent Multi-Netting (CMN-4) into LMMT for Capability Drop (CD) 4 capabilities.

The details of Program Element 0604280N, Project 1411 are classified SECRET//NOFORN and are submitted to Congress in the classified budget justification books.

Mission — Naval Coastal Warfare Surv and C4I Sys source

The Navy Expeditionary C4I project supports the Navy Expeditionary Combat Command (NECC) mission to detect, deter or interdict potential threats to DoN assets using agile, modular and scalable technology. NECC units have a number of current and future Command, Control, Communications, Computers & Intelligence (C4I) technological requirements for Tactical/Command Operations Center, tactical vehicles, combatant craft, and dismounted personnel. NECC operations require units to maintain effective command and control, develop and display a common tactical picture, and share intelligence and current operational information with higher headquarters, subordinate units, joint forces and coalition allies. Small, Medium, and Large Scale Communication Systems (LSCS) are the C4I hub for the Navy Expeditionary Combat Force (NECF); Expeditionary Deployable Node (EDN) is the latest converged LSCS baseline. Future C4I research and development includes implementation of The Expeditionary Deployable Node (EDN) and Navy Expeditionary Tactical Entry Points (NExTEP) at the Fleet Network Operations Centers (NOC), which supports the NECC Type Commander's (TYCOM) vision of a smaller footprint C2 system with reduced Fleet administration and patching requirements and a single domain and single user identity across all deployed systems. Future C4I research and development will enhance information transport, network cyber security posture, assured communications in denied environments along with agility and mobility. Funding is required for testing and evaluation of cyber security issues associated with obsolescence of network items and if not addressed will impact the ability of the Program Office to maintain system accreditation under Risk Management Framework (RMF) revoking multiple LSCS assets authority to connectivity on the Department of Defense Information Network (DoDIN). Efforts are in alignment with NECC's strategic Expeditionary Warfare Improvement Program (EXWIP) Integrated Priority Capability List (IPCL) priorities and maintain alignment with greater DoD initiatives, such as Joint Information Environment (JIE), Mission Partner Environment (MPE) in order to maintain interoperability and drive down DoN enterprise costs.

Mission — Network Tactical Common Data Link source

Network Tactical Common Data Link (NTCDL) provides the ability to transmit/receive real-time Intelligence, Surveillance, and Reconnaissance (ISR) data simultaneously from multiple sources (surface, airborne, sub-surface, man-portable), and exchange command and control information (voice, data, imagery, and Full Motion Video) across dissimilar joint, service, coalition, and civil networks. NTCDL provides warfighters with the capability to support multiple, simultaneous, networked operations with currently fielded Common Data Link (CDL)-equipped air platforms (e.g. MH-60R), in addition to next generation manned and unmanned platforms (e.g., P-8, Triton, MQ-25 (Stingray), small tactical unmanned aircraft systems (STUAS) and Fire Scout). NTCDL is an incremental capability (surface, airborne, sub-surface, and man-portable) providing modular, scalable, multiple-link networked communications. NTCDL benefits the fleet by providing a horizon extension for line-of-sight sensor systems for use in time-critical strike missions and supports tasking, collection, processing, exploitation, and dissemination (TCPED) via its ISR networking capability. NTCDL supports Resilient Command and Control (RC2) through its relay capability, and supports TCPED through its ISR networking capability. FY 2026 request is for NTCDL to continue Capability Enhancement Development including Bandwidth Efficient Common Datalink (BE-CDL) waveform implementation.

Mission — Digital Modular Radio source

Digital Modular Radio (DMR) with Integrated Waveform (IW) and Mobile User Objective System (MUOS) capable hardware is the Navy's technical solution for the IW/MUOS requirement. The compact, multi-channel DMR provides 3G, Wideband Code Division Multiple Access (WCDMA) technology, for high speed/capacity voice and data satellite communications. DMR radios currently operate aboard U.S. Navy surface and subsurface vessels, fixed-sites and other Department of Defense (DoD) communication platforms using frequencies ranging from 2 MHz to 2 GHz. Certified to pass secure voice and data at Multiple Independent Levels of Security (MILS) over High Frequency (HF), Very High Frequency (VHF), Ultra High Frequency (UHF), and Satellite Communications (SATCOM) channels, the DMR system was developed to the U.S. Navy's specifications and meets all the stringent environmental, Electromagnetic Interference (EMI) and performance requirements for use in the U.S. Fleet. This system is formally specified by both Fleet Commanders as a threshold capability, for global maritime command control and communications in a Distributed Maritime Environment, to execute current warfighting plans and is required for National Command and Control capability. This program is for continued development/integration of the IW and MUOS waveforms into the DMR in accordance with Military Standards 188-181,2,3. Additionally, the enhancements of High Frequency Distribution Amplifier Group (HFDAG) and, HF Automated Link Establishment (ALE) and Second-Generation Anti-Jam Tactical UHF Radio for NATO (SATURN) will also be developed/integrated into the DMR. HFDAG is a follow-on HF solution to fulfill transmit and receive HF communication capability with various modes of operation, such as ALE, for Navy platforms. HFDAG will utilize the existing DMR as the exciter/receiver. Generation 3 (GEN 3) HF ALE/HF wideband provides Navy users with improved HF communications, increased transmission rates from radio to radio, and serves as a supplement to SATCOM when SATCOM networks are overloaded or unavailable. SATURN is the follow-on HAVEQUICK II anti-jamming solution in accordance with NATO Standardization Agreement 4372. SATURN capability will counter adversaries' jamming efforts and ensure Navy's Assured Command and Control UHF communications operational end-to-end capability as well as enhance interoperability within/between DMR users and with Allied/Coalition partners. IW uses a Time Division Multiple Access (TDMA) communication system in an attempt to improve satellite bandwidth utilization over legacy SATCOM waveforms. This enables demand assigned services on UHF SATCOM networks to support new applications that require better performance and higher channel throughput. The MUOS waveform will enable MUOS satellites to provide worldwide communication satellite coverage for DoD requirements. MUOS will provide functionality comparable to commercial mobile phone systems. In FY 2026, the program will complete MUOS 3.2 and SATURN development integration and test efforts with the DMR. DMR will begin the design, testing, and integration of a follow-on tactical communication solution that will deliver critical cryptographic compliant waveforms to the fleet.

Mission — MIDS/JTRS source

The Multifunctional Information Distribution System (MIDS) is the most widely fielded family of Tactical Data Link radio terminals in the world. The MIDS program office is the Performing Activity for the Navy (Lead Service for Department of Defense (DOD)), Link 16 capability and consists of two (2) product lines, MIDS Low Volume Terminal (LVT) (legacy hardware defined radio) and MIDS Joint Tactical Radio System (JTRS) (software defined radio). MIDS-LVT effort is a cooperative development program between France, Germany, Italy, Spain, and the United States with United States joint service participation (Navy, Army, Air Force), and has provided over 12,000 terminals to more than 50 Nations providing interoperability with North Atlantic Treaty Organization (NATO) and coalition partners. The Department of Defense (DoD) established the program to design, develop, and deliver low volume, lightweight tactical information system terminals for U.S. and allied fighter aircraft, bombers, helicopters, ships, and ground sites. MIDS-LVT significantly increases force effectiveness and minimizes hostile actions and friend-on-friend engagements. MIDS-LVT Block Upgrade 2 was executed as an Engineering Change Proposal (ECP) and provides the critical upgrades to the MIDS-LVT Terminal to enable U.S., Coalition and International partners' ability to meet the National Security Agency (NSA) mandated timelines for Cryptographic Modernization (CM) and the National Telecommunications and Information Agency (NTIA) and Federal Aviation Agency (FAA) mandated timelines for Frequency Remapping (FR). MIDS JTRS, designed as a Pre-Planned Product Improvement (P3I) and executed as an ECP to the production MIDS-LVT configuration, and is fully compatible with MIDS-LVT. The MIDS JTRS Core Terminal achieved Full Production & Fielding (FP&F) in March 2012. It facilitated the JTRS incremental approach for fielding advanced JTRS transformational networking capability and transformed the MIDS-LVT into a 4-channel, SW Communications Architecture (SCA) compliant, Joint Tactical Radio. A form-fit-function replacement to MIDS-LVT, MIDS JTRS also adds three programmable 2 Megahertz (MHz) to 2 Gigahertz (GHz) channels capable of hosting the JTRS legacy and networking waveforms. In addition to Link 16, Tactical Air Navigation (TACAN), and voice functionality found in MIDS-LVT, MIDS JTRS has four channels and adds capabilities such as Link 16 Enhanced Throughput (ET), Link 16 FR, SW programmability, CM, and Four Net Concurrent Multi-Netting with Concurrent Contention Receive (CMN-4). MIDS JTRS Tactical Targeting Network Technology (TTNT), is a block upgrade to the MIDS JTRS CMN-4 Terminal providing an Internet Protocol-based networking capability on tactical aircraft. TTNT is a low latency, high throughput waveform that has the capability to support data exchange between fast-moving tactical aircraft, weapons, and unmanned aircraft, in addition to air, land, and sea-based command and control nodes, in a variety of air-to-air and air-to-ground missions including time sensitive targeting, air warfare, close air support, non-traditional ISR, and anti-surface warfare. TTNT and MIDS JTRS CMN-4 directly supports Naval Integrated Fire Control (NIFC) capability requirements. These capabilities provide Joint Airborne Network-Tactical Edge functionality to run advanced mission applications in a cross-platform/cross-domain tactical network enterprise. Currently when updated software or any bug fixes are available, the warfighter must return the terminal to the vendor and pay for the labor to install the latest software push. With the new Field Loadable capability, the vendors will update the terminal's software to allow the warfighter to use the front panel of the terminal to load the latest software build in the field. The Field Loadable capability entails updating and rewriting the specifications documents for the front panel, new software to enable users in the field to push updates and retrofitting government furnished equipment for use in the new testing environments. The FY 2026 Budget begins Electromagnetic Compatibility Features (EMCF) test automation and regression testing for MIDS JTRS/TTNT and MIDS-LVT variants to accelerate the certification process. It also completes the Integrated Software Build 9.2, Block Cycle 2 for fleet release of various updated capabilities (specific capabilities classified) while beginning the integration of new software enhancements for the next baseline. TACAIR RIL continues to demonstrate emerging technologies, innovations and threat-based evaluations.
