(U) The Advanced EHF program provides the follow-on capability to the Milstar satellite program. It provides the basis for the next generation military communications satellite system, for survivable, jam-resistant, worldwide, secure, communications for the strategic and tactical warfighter. The system replenishes the Milstar constellation in the EHF band.
(U) The Advanced Extremely High Frequency (EHF) program provides the follow-on capability to the Milstar I and II satellites. Advanced EHF uses standardized spacecraft components which will be launched on a Medium Launch Vehicle (MLV). The requirement is for the Advanced EHF satellite to have one single channel protected data rate of six to eight Mbps using the existing Milstar II Medium Data Rate (MDR) waveform. This development will be an incremental step towards the single channel protected service on the EHF Replenishment satellite that will provide 10s of Mbps. The Advanced EHF capability will be available for first launch not later than 2006.
(U) Without an Advanced EHF system to replace Milstar, the DoD will be left without any protected communications capability to support the NCA, SIOP, and many other strategic and tactical military requirements.
