Although DoD’s uhF sATcom is protected by encryption, it is not designed with anti-jam, low prob- ability of intercept (Lpi), or low probability of detection (LpD) capabilities. While one could certainly see the utility of these features in many military applications, the absence of this functionality keeps the design of these uhF sATcom systems relatively simple. This helps keep terminal costs low compared with other DoD miLsATcom systems and allows DoD to eld tens of thousands of uhF sATcom terminals for the war ghter.
