...U.S. Air Force Family of Advanced Beyond Line-of-Sight Terminal (FAB-T) program, which will provide protected wideband satellite communications among ground and airborne terminals for the command and control of U.S. nuclear forces. The Boeing FAB-T team has completed software qualification testing and systems integration testing on the FAB-T development program. The team also has demonstrated FAB-T's integration with the Advanced Extremely High Frequency (AEHF) and Milstar mission control subsystem, which commands both satellite constellations. Conducted in Boeing's factory, this test validated FAB-T's ability to control strategic satellite communications payloads on orbit. The AEHF and Milstar satellite constellations will relay FAB-T communications once FAB-T is operational.

During testing, FAB-T also transmitted data using both low-data-rate and extended-data-rate (XDR) communications protocols. The system's advanced XDR capability offers Internet-like functionality and improved speed compared with earlier systems and software. In April 2012, Boeing and the Air Force agreed on a set of additional FAB-T capabilities, including Presidential and National Voice Conferencing, to be developed under Boeing's firm fixed-price contract. The Boeing team has implemented those capabilities and expects to enter functional qualification testing early this year.
