Mission Network: At-The-Halt


The Tactical Network Transport At The Halt (TNT ATH) capability provides mission command and the full range of voice, video, and data communications Soldiers and commanders need to be successful in today’s missions. This robust line-of-sight and beyond-line-of-sight network communications capability successfully meets the Army’s ATH operational requirements.

To support expanding network requirements and improve the readiness of today’s operational force, the Army continues to modernize the ATH capability, increasing and optimizing bandwidth, improving capability, mobility and interoperability, while increasing resiliency in contested environments. The 5th Generation Technology Insertion (5th Gen TI) is the next effort that will refresh the Army’s TNT ATH equipment, which is reaching end of life. Using a “One Network” approach, the 5th Gen TI leverages new technology and pre-existing Tactical Network products for a common user experience. It will provide more compute power, reduce size, weight and power (SWaP) and equipment setup time for increased mobility, while increasing usability, network resiliency and equipment flexibility. PdM Mission Network is currently piloting the new 5th Gen TI prototype solutions.

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 Tactical Hub Node (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.
  • The Satellite Transportable Terminal (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 size, weight and power (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.   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

The Army’s Expeditionary Signal Battalion-Enhanced (ESB-E) Pilot will provide valuable feedback to shape future equipment solutions and the force structure for the service’s 24 ESBs. In support of this pilot effort, PM Tactical Network delivered an innovative mix of smaller, lighter more mobile Tactical Network Transport Equipment, compared to that of traditional ESBs that use legacy At-The-Halt Tactical Network Transport equipment. The ESB-E’s new prototype line-of-sight and beyond-line-of-sight expeditionary equipment package will enable 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 the ESB-E to support elements from small teams to corps sized elements, and a wide variety of mission sets.
