Abstract : A system interfaces classified information for encryption and transmission over ultra high frequency (uhf) or high frequency (hf) bands and for receiving and decryption of uhf and hf information for relay to a tactical data unit or a vocoder unit. The uhf link is relayed by satellite while the hf link follows a more conventional path to provide for backup in case one link or the other somehow is disabled. Optionally, a uhf submarine-satellite information exchange capability system (SSIXS) is included when the rest of the system is not utilized. (Author)
