On 3 August 1950 the re-activation of the USS Haynsworth commenced due to our countries involvement in the Korean War. The Haynsworth recommissioned at Charleston 22 September 1950, and Cmdr. Herbert F. Rommel was selected as it's new skipper. The hastily gathered crew was assembled from various other ships and over half were comprised of reservists. Shortly the ship limped to Norfolk VA where with the assistance of the Naval Shipyard, and a Destroyer Tender, and our Crew, the Haynsworth was once more made "Sea Worthy".

Next the ship sailed to Guantanamo Bay, Cuba for a three-week shakedown cruise, followed by another three month overhaul back in Charleston. Following this overhaul, the ship returned to Guantanamo Bay, Cuba for seven more arduous weeks of extensive training, over much of the Caribbean.

Then during the first half of 1951 more gunnery, anti-submarine etc. training in the Virginia Capes area, finally, in August 1951, Rear Adm. Solomon held a departure inspection and on 3 September 1951 the ship set sail for six months duty in the Mediterranean.

After returning to United States the ship and it's crew were delegated to still more training and operations along the East Coast and in the Caribbean.

1953 Through 1959:
The Korean War ended on July 27, 1953.
Next assignment was a Midshipman cruise to the North Atlantic, Haynsworth sailed from Norfolk 2 November 1953 for a round-the-world cruise. Next assigned to the Pacific for 4 months duty in the Far East with the 7th Fleet, a vital peace keeping force in that part of the world.

Haynsworth returned to Norfolk 4 June 1954 to resume her support of the 6th fleet.

In 1956 with the Suez crisis still unsettled, Navy units stood by in the eastern Mediterranean and evacuated U.S. nationals from Egypt. Haynsworth aided the Navy's preparedness in the event of any conflict. Between 1956 and 1960 she made five deployments to the Mediterranean, supporting the Navy's peacekeeping role and keeping a watchful eye on the troubled spots of the free world.

In 1959 Haynsworth took part in the historic "Operation Inland Seas," commemorating the opening of the mighty St. Lawrence Seaway, by steaming up the St. Lawrence to Montreal.
