The details of Program Element 0604280N, Project 0728 for NMT are classified SECRET//NOFORN and are submitted to Congress in the classified budget justification books. Technology Insertion, studies and implementation is necessary for military satellite communications systems development to support emerging technologies for Satellite Communications (SATCOM) programs. This project funds the testing and integration of the modem and processing equipment enabling a Non-Geostationary Orbit (NGSO) system to operate on Navy submarines. The project awarded a contract to a Prime Mission Product (PMP) vendor to develop and test hardware and software to produce an Engineering Development Model (EDM). Increase of $43.479M from FY 2026 to FY 2027 will support major development milestones in FY 2027. FY 2027 funding will support mandated Navy Multiband Terminal (NMT) software and hardware system upgrades required for interoperability with the Evolved Strategic SATCOM (ESS) constellation. In addition, FY 2027 funding will support Wideband Anti-Jam Modem System (WAMS) development, testing, integration, and certification efforts. This provides Resilient Command, Control, and Communications (RC3) and Distributed Maritime Operations (DMO) capability. FY 2027 funding also supports the SATCOM NGSO Technology Insertion Critical Design Review (CDR), Test Readiness Review (TRR), and Engineering Development Model (EDM) vendor design testing, preparing for Production Representative Asset (PRA) delivery in FY 2028.

The funding increase of $4.688M from FY 2026 to FY 2027 is due to the commencement of LN-251M and ANAV-3M interim solution testing for E-2D, P-8, F/A-18E/F, and EA-18G platforms. 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 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 War (DOW)), 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 War (DoW) 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.

Advanced Tactical Data Link Systems (ATDLS) is the United States (US) Navy's only ship-to-ship/ship-to-aircraft tactical information solution equipping warfighters and Combatant Commanders with real-time battlespace data and extending the range of lethality. ATDLS is the backbone of Carrier Strike Group and AEGIS-Based Defense operations and is the key component in the fire control loop, providing critical track information for enabling maritime offense/defense, Joint Area Domain Command and Control (JADC2), Integrated Air and Missile Defense (IAMD), Ballistic Missile Defense (BMD), Anti-Air Warfare (AAW), Anti-Surface Warfare (ASuW), Electronic Warfare (EW), Advanced Offboard Electronic Warfare (AOEW), and Long Range Fires (LRF) missions. ATDLS Integration Program develops new and improved Tactical Data Links (TDL) networking capabilities, delivering operational and targeting support to the warfighter. ATDLS rapidly and securely connects carrier/shipboard digital combat systems to military aircraft, ground troops, coalition partners, and space assets with vital Situational Awareness, targeting, and sensor information. ATDLS also provides Joint Range Extension capability via Link 16 Network (Link 16) Terminals, Command and Control Processor (C2P), and Link Monitoring and Management Tool (LMMT). Link 16 Network (Link 16) Increment II: Link 16, enhanced by Tactical Targeting Networking Technology (TTNT), is the Military's only joint network providing secure TDL interoperability and data sharing in contested battlespace environments. The Link 16 development initiatives 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) Modification of 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.
