Satellite Communications: T2C2


The Transportable Tactical Command Communications (T2C2) program of record is an initial entry satellite system that provides agile robust voice, video and data communications without the need of static infrastructure. The system is easy to use and can be operated by non-signal Soldiers. T2C2 Lite (1.2 meter tri-band) and T2C2 Heavy (2.4 meter tri-band) high-bandwidth inflatable satellite terminals enable initial entry forces to connect to the Army’s tactical network to obtain the situational awareness and mission command capabilities needed to conduct initial entry operations and set the stage for follow-on forces. In more mature operations, T2C2 Heavy will provide high bandwidth tactical network extension to company level and small forward operating bases and T2C2 Lite will support special teams in austere locations with high bandwidth requirements.

T2C2 provides satellite capability to small detachments and teams operating in remote locations without network infrastructure, enabling them to securely relay critical and time sensitive information, increasing the situational awareness for the entire operation. The system greatly increases throughput over legacy systems by taking advantage of military satellite capability. Because the T2C2 solution is inflatable, it can provide a larger dish size, with increased capability and bandwidth efficiency, in a smaller transportable package. These highly expeditionary inflatable satellite antennas provide the commander with increased operational flexibility and speed in maneuver.

Scalable Class of Unified Terminals (SCOUTs) provide compact low-bandwidth beyond-line-of-sight communications for transmission of secure and non-secure data, voice, and video, all in a compact package supporting the team level and above. Variants of the SCOUT Medium (1.3 meter dish) support the Army’s Security Force Assistance Brigades (SFABs) and the Integrated Tactical Network (ITN), and the SCOUT Small (0.65/0.95 meter) supports numerous expeditionary requirements.

Until T2C2 fielding is complete, Secure Internet Protocol Router Network/Non-Secure Internet Protocol Router (SIPR/NIPR) Access Points (SNAPs) and even smaller suitcase-sized Global Rapid Response Information Packages (GRRIPs) are being used as bridging capability.

T2C2 is a key component of the Army’s Capability Set (CS) 21 Expeditionary Signal Battalion-Enhanced network tool suite, which will be fielded to modernize the Army’s ESBs.

T2C2 directly supports and is aligned with the Army Network Modernization Strategy Line Of Effort (LOE) #1 Unified Network; it is fully interoperable with the Army’s Tactical Network and architecture, and provides expeditionary network transport. It also supports LOE #4 Command Post Mobility and Survivability, by providing an easy to deploy, quick set up/tear down communications solution to enable units to relocate rapidly, while delivering critical real-time battlefield situational awareness to keep forces safe and ensure mission success.
