Mission Network: At-The-Halt


Tactical Network Transport - At The Halt (TNT- ATH) enables mission command and robust voice, video, and data communications for global data exchange from anywhere on the planet. These robust line-of-sight and beyond-line-of-sight network communications systems operate at-the-halt and deliver a real-time common operating picture to enable Commanders to make rapid informed decisions. To support expanding network requirements and improve the readiness of today’s operational force, the Army continues to modernize the ATH capability, improving mobility, computing power, and interoperability, while optimizing and increasing bandwidth and resiliency in congested and contested environments.

The Network Integration Technology Enhancement (NITE) is the next modernization effort that will refresh the Army’s widely fielded TNT-ATH equipment, which is reaching end of life. Using a unified network approach, NITE leverages new technology and pre-existing Tactical Network products for a common user experience. This modular solution will provide more computing power, reduce size, weight and power (SWaP) and equipment setup time for increased mobility, while increasing usability, network resiliency and equipment flexibility. PM Tactical Network is currently piloting the new NITE prototype solutions, leveraging Soldier feedback to inform design and fielding decisions.

PM Tactical Network will also pilot enhanced Tactical Hub Node (THN) and Satellite Transportable Terminal (STT) prototypes to modernize these configuration items as well.

TNT-ATH modernization efforts support and are aligned with the Army Network Modernization Strategy Line Of Effort #1 Unified Network and #4 Command Post Mobility and Survivability.

Main Components

  • The Army’s TNT-ATH has three main transportable network nodes that provide high-speed wide area network capability for secure voice, video and data exchange. The THN and Joint Network Node (JNN) support division headquarters; the JNN also supports brigade combat team level headquarters; and the Command Post Node (CPN) supports battalion level headquarters and smaller-sized units.
  • STT is a highly transportable and mobile satellite system, which operates in conjunction with the JNN and CPN. It is designed to establish secure voice, video and data communications virtually anytime and anywhere. As part of its network modernization efforts, the Army is upgrading its fleet of STTs to increase capability, modularity, mobility, and operational flexibility, while reducing SWaP for a more expeditionary force.
  • The largest type of network node, the Regional Hub Node (RHN), is a fixed installation equivalent to three THNs and is used to support theater level operations. The five regionally located RHNs enable global connectivity to transport information within theater and around the world. They support joint training and real-world contingency operations, as well as humanitarian, disaster relief and national emergency response.
    • The Global Agile Integrated Transport (GAIT) network design interconnects the RHNs -- and can also interconnect Department of Defense (DOD) Teleport Sites -- to create a global network mesh that enables high-capacity data exchange from anywhere on the planet. Additionally, with the evolution of the architecture, units can now also choose to transport data directly between the approximately 125 GAIT Points of Presence (PoPs) -- located at military formations, including divisions, corps, theater tactical signal brigades and special users – without the need to leverage the RHNs or teleports. This simplifies network transport even further, and adds multipath diversity to increase network robustness and resiliency. GAIT enables commands with dispersed units around the globe to maintain mission command and Network Operations capabilities from their home station or forward- deployed headquarters. GAIT delivers a more unified and robust network, enabling current expeditionary network capabilities and laying the ground work for future network transport innovation.

Additional Pilot Efforts

As part of the Army’s Capability Set 21 network modernization efforts, the Expeditionary Signal Battalion-Enhanced (ESB-E) Pilot provided valuable feedback to shape equipment solutions and force structure to enhance the service’s 24 ESBs. In support of this pilot effort, PM Tactical Network delivered an innovative mix of smaller, lighter more mobile and expeditionary Tactical Network Transport equipment that eliminated the need for traditional TNT-ATH equipment. The final ESB-E’s line-of-sight and beyond-line-of-sight expeditionary equipment package enables uninterrupted mission command and the ability to rapidly deploy and maneuver across the battlefield in support of other units. The equipment tool suite is also tailorable and scalable to enable new ESB-Es to support small teams to corps sized elements, and a wide variety of mission sets.
