Mission Network: RHN & GAIT


Regional Hub Nodes (RHNs) are the largest transport nodes for the Army’s tactical network. The five regionally located RHNs enable global connectivity to transport information from intra-inter theater tactical networks around the world. They support current and contingency operations, humanitarian disaster relief and national emergency response.

The five RHNs are at the upper-most level of the Army’s tactical network architecture, and their innovative baseband and satellite communications capabilities enable regionalized reach-back to the Army’s global network. They enable the transport of information across the tactical network in and out of theater and around the world. The RHNs operate out of the conflict area and give the Soldier in the field immediate access to secure and non-secure internet and voice communications anywhere on the globe. To provide tactical users with secure, reliable connectivity worldwide, the Army has positioned RHNs in five separate regions: Continental United States (CONUS) East and CONUS West, Central Command, European Command and Pacific Command.

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 fluid data exchange from anywhere on the planet. GAIT provides more routing options, more paths and solutions for data to flow through allowing the Army to leverage the global network more efficiently and effectively. The GAIT delivers a more unified and robust network, enabling current expeditionary network capabilities and laying the ground work for future network transport innovation.


  • RHNs are currently used by both deployed Marine Corps and Army units.
  • RHNs possess full Network Operations capabilities for network monitoring, management and trends analysis, as well as information assurance tools.
  • RHN Commercial Internet and Phone (COM-IP) package supports contingency operations, disaster relief or U.S. homeland emergency response.
  • Leveraging GAIT, commands with dispersed units around the globe can maintain mission command and Network Operations (NetOps) capabilities from their home station or forward- deployed headquarters.
  • GAIT enables and enhances new capabilities, including Enroute Mission Command (EMC), Transportable Tactical Command Communications (T2C2), Modular Communications Node-Advanced Enclave (MCN-AE), Secure, Mobile, Anti-Jam, Reliable, Tactical–Terminal (SMART-T), and Disaster Incident Response Emergency Communications Terminal (DIRECT).
