Air Force MILSATCOM Terminal Programs Office (MTPO)


Military Satellite Communications Systems Directorate develops, acquires and operationally deploys communication terminals synchronized to support satellite weapon system operations and provides support for 16,000 aircraft, transportable and fixed site terminals.


MILSATCOM is responsible for the acquisition of satellite communication terminals in very, ultra, super and extremely high frequency (VHF, UHF, SHF and EHF) and optical bands. The Directorate is also responsible for the installation, maintenance, upgrade and removal of the Army-developed, Enterprise Wideband SATCOM Terminals at Air Force sites, a.k.a. AFWET. As Joint assets and part of the Global Information Grid, these terminals provide worldwide, wideband SATCOM for strategic and tactical command, control, communications and intelligence, surveillance, and reconnaissance users.


Protected Extremely High Frequency (EHF) terminals provide worldwide jam-resistant, survivable communications, which ensuring a low probability of intercept/detection communications for National and strategic leadership. These terminals operate with a number of EHF-capable satellites, to include the Milstar and the Advanced EHF (AEHF) constellations. EHF terminal programs include the current Milstar Command Post Terminal that supports global command and control of strategic forces, and the Family of Advanced Beyond-Line-of-Sight Terminals (FAB-T). The FAB-T Program acquisition program will be providing a family of Beyond Line-of-Sight SATCOM terminals with an open architecture development. The FAB-T Program will deliver multi-mission capable, ground-based and aircraft qualified SATCOM terminals.

Wideband terminals provide global communications with high data rates. The Directorate is currently procuring the Ground Multi-band Terminal, a quad-band (C, X, Ku and Ka) terminal that provides the warfighter with flexible, integrated tactical communications. The High Data Rate-Radio Frequency Ground Terminal program is an evolutionary upgrade to the GMT. The program will provide the high data rate SATCOM needed to support the ISR community with High Bandwidth High Throughput capability. HDR-RF Ground Terminals will be interoperable with FAB-T and will support the full spectrum of operations from humanitarian support/disaster relief to a major theater war. Air Force Wideband Enterprise Terminals provide both secure and unsecure voice, networked data and video teleconference services to the warfighter.

Terminals in the narrowband frequency range provide worldwide, assured, low data rate (up to 56 Kbps) satellite communication. These terminals incorporate the Joint Staff directed Demand Assigned Multiple Access functionality, pooling all unused resources which increase availability for users. The Air Force is currently fielding the new Airborne Integrated Terminal Group which provides communications for bombers, ISR aircraft and other missions.
