Naval Tactical Data System
A highly versatile multi-mission destroyer, "Fletcher" was capable of operating independently or in company with Amphibious or Carrier Task Forces. Her main mission was to operate offensively in a Strike Warfare or Anti-Submarine Warfare (ASW) role. The Tomahawk Weapons Systems provided "Fletcher" with long range cruise missile capability for use in tactical strike operations. The ship's primary passive ASW sensor was the AN/SQR-19 Tactical Towed Array Sonar (TACTAS). Its active sonar together with the Mk 116 Underwater Fire Control System combined as one of the most advanced underwater detection and fire control systems ever developed. The Naval Tactical Data System (NTDS) provided the ship with faster and more accurate processing of target information. Integration of the ship's digital gun fire control system in the NTDS provided quick reaction in the mission areas of shore bombardment, Anti-Surface, and Anti-Aircraft Warfare.
