ATDLS

The Advanced Tactical Data Link Systems (ATDLS) program is a critical Navy procurement initiative under P-1 Line Item 2614, focused on delivering and modernizing ship-to-ship and ship-to-aircraft tactical data link capabilities. The primary goal of ATDLS is to equip warfighters and Combatant Commanders with real-time, secure battlespace information, thereby enhancing situational awareness and extending the range and effectiveness of maritime operations. ATDLS serves as the backbone of Carrier Strike Group and AEGIS-Based Defense operations. It supports key mission areas such as Joint All-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), and Long Range Fires (LRF).

The ATDLS Integration Program develops and fields new and improved Tactical Data Link (TDL) networking capabilities, ensuring that Navy platforms can securely and rapidly exchange operational and targeting data with aircraft, ground forces, coalition partners, and space assets. This integration is achieved through the procurement and installation of Link 16 Network Terminals, Link 16 Antennas, Command and Control Processor (C2P) hardware and software, and the Link Monitoring Management Tool (LMMT). These components collectively enable the Navy to maintain robust, interoperable, and resilient communications across the joint force and with allied nations.

The Command and Control Processor (C2P) Technology Refresh (TR) and Modernization (MOD) is a key objective within ATDLS. C2P is the only shipboard solution that enables bi-directional exchange of tactical information across multiple TDLs, including Link 11, Link 16, Satellite TDL J, and Joint Range Extension Applications Protocol (JREAP). The modernization effort includes a technology refresh to address hardware obsolescence, software upgrades for improved capability and cybersecurity, and the addition of Link 22 to enhance coalition interoperability. C2P MOD also supports agile DevSecOps software deployment, allowing for rapid capability and security updates to maintain continuous kill chain improvements.

The Link 16 Terminal Ship/Shore Modernization line item focuses on integrating and updating Multifunctional Information Distribution System Joint Tactical Radio System (MIDS JTRS) terminals into Navy shipboard environments. This modernization is guided by Joint Chiefs of Staff requirements and includes enhancements such as Crypto Modernization, Frequency Remapping, Enhanced Throughput, Concurrent Multi-Netting, and Current Contention Receive. The program also funds the replacement of legacy Link 16 antennas with higher-throughput models to ensure reliable, secure communications in contested environments.

The Link Monitoring Management Tool (LMMT) provides Joint Interface Control Officers (JICOs) and Maritime Operations Centers (MOCs) with the ability to monitor and manage TDL network performance within designated Areas of Responsibility. LMMT modernization supports the Navy's ability to Fight from the MOC and enables MOC-in-the-Middle functions, which are essential for JADC2 and BMD missions. The procurement and installation of LMMT hardware and software ensures effective network management and operational oversight for distributed maritime operations.

The ATDLS Training line item funds the development of integrated, end-to-end training products and simulators for all TDL functionalities, including C2P, LMMT, and the Link 16 family of systems. This training is necessary to ensure that operators are proficient in using the latest capabilities as they are fielded, supporting readiness and effective employment of advanced data link systems across the fleet. The curriculum and simulator development align with the multi-year fielding schedule of new capabilities.
