"McCloy" deployed to the Mediterranean from January to June 1981. During this time frame, her Passive Anti-Submarine Towed Array Sonar Surveillance System (TASS) proved highly capable and successful in extensive tracking of submarines. "McCloy" returned to her home port in Norfolk, Virginia in June 1981 only to be sent to sea again on short notice to conduct additional Special ASW operations in the Bermuda "Box". "McCloy" departed Norfolk for another Mediterranean Deployment (MED 5–82) from July to December 1982. Using her primary weapon system, her TASS passive sonar system (a system of passive hydrophones towed behind the ship), she was immediately assigned to tracking of Soviet submarines in the Mediterranean.
