The Impeccable-class ocean surveillance ship is a single-ship class of United States Navy special mission-support ship. The original intention was to build six undersea ocean-surveillance ships carrying a SURTASS passive towed array and a Low Frequency Active transducer array. Only the lead ship, USNS Impeccable (T-AGOS-23), was built.
