The AN/USC-28(V) Satellite Communications Set (SCS) operates over the Defense Satellite Communications System (DSCS) Phase II & III satellites. It is an Electronic Counter-Counter Measures (ECCM) communications system which provides jam resistant, secure communications for departmental user networks by employing code division spread spectrum modulation techniques.

The system also accommodates command, control, and performance assessment of the ECCM network by the DSCS Operational Control System (DOCS) and Contingency (CDOCS) via orderwire overhead communications channels. The AN/USC-28(V) is comprised of four distinct software baselines, each associated with its correspondent hardware configuration, i.e., the Ground Normal Version, the Dual Waveform Version, the Hybrid Version, and the Airborne Mitigated Version.

Except for the Ground Normal Version, the AN/USC-28(V) is capable of maintaining the communications in the presence of signal propagation anomalies caused by high altitude nuclear detonation, both during and after the event.
