Naval Tactical Data System
The upgraded combat system would include the MK86 Gun Fire Control System with AN/SPQ-9 radar, the Hughes AN/SPS-52C 3D radar, the AN/SPG-51C (Digital) Fire Control Radars, and the Naval Tactical Data System (NTDS). These ships were also planned to have the ability to launch several "Harpoon" antiship missiles, which were to be installed in their MK-11 or MK-13 Tartar missile launcher.
