Note that <i>Tattnall</i> was one of only three <i>Charles F. Adams</i>-class destroyers to receive the New Threat Upgrade (NTU). This consisted of a number of sensor, weapons and communications upgrades that were intended to extend the service lives of the ships. Under the NTU, these destroyers received improved electronic warfare capability through the installation of the AN/SLQ-32(V)2 EW Suite. The upgraded combat system includee the Mark 86 gun fire control system with AN/SPQ-9 radar and the AN/SPG-60 fire control radar (both visible above the bridge), Hughes AN/SPS-52C 3D radar, AN/SPG-51C (digital) fire control radars, and the Naval Tactical Data System (NTDS).
