On 3 July, "Barry" received an upgrade to her AN/SQS-23 sonar at Hellenic Shipyards, Athens. Port visits to Istanbul, Turkey and Thessaloniki, Greece. In October, Barry was undergoing repairs in the shipyard in Parama, Greece. All hands were recalled to the ship during the night, to begin the assembly of the ship in preparation for deployment as an ASW screen ship for the Marine Landing Battalion stationed off the Suez in response to the Soviet naval buildup during the Arab–Israeli war. After receiving clearance to operate "Barry" steamed to join the 6th Fleet's Amphibious Task Forces. On 16 November, while on reserve station south of Crete, a Marine CH-46 helicopter from lost engine power during a routine flight while hovering above "Barry". The craft, with crewmen aboard, crashed into the destroyer's ASROC deck, rolled over the starboard side, and almost immediately sank. No one on "Barry" was injured, and two of the three helicopter crewmen were rescued by the ship's Motor Whale Boat. The ship was immediately sent back to flight quarters to receive a flight surgeon by helicopter to treat the injured airman. Barry returned to Athens for Thanksgiving before resuming further contingency operations, mostly as carrier escort, which lasted until the end of the year.
