Construction and commissioning
Walworth County was laid down as USS LST-1164 on 22 September 1952 at Pascagoula, Mississippi by the Ingalls Shipbuilding Corporation. She was launched on 15 May 1953, sponsored by Mrs. John A. Furr, and commissioned on 26 October 1953, Lieutenant F. Kay in command.

Operations in U.S. waters 1953-1956
LST-1164 departed Pascagoula on 20 November 1953, bound for Norfolk, Virginia. She conducted shakedown in the Chesapeake Bay and became a unit of Landing Ship Tank Division 23. The ship arrived at her home port of Naval Amphibious Base Little Creek, Virginia Beach, Virginia, on 3 December 1953. On 6 April 1954, LST-1164 departed the amphibious base for a brief stop at the United States Naval Reserve training center at Jacksonville, Florida. On 19 April 1954, the ship took part in simulated nuclear warfare strikes and returned to Little Creek on 25 May 1954.

LST-1164 spent June 1954 participating in amphibious exercises at Vieques Island, Puerto Rico. LST-1164 returned to Little Creek on 11 July 1954 for voyage repairs in the Norfolk Naval Shipyard in Portsmouth, Virginia, and towing exercises off Little Creek beach.

From 3 November 1954 through 24 March 1955, the ship participated in various exercises with the United States Marine Corps and the United States Army in the areas of Camp Pendleton, Virginia; Onslow Beach, North Carolina; and Vieques Island, Puerto Rico.

On 30 March 1955, LST-1164 entered the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, for a four-month overhaul. During that period, she was named USS Walworth County (LST-1164) on 1 July 1955. She returned to Little Creek on 5 August 1955 and conducted exercises in the Chesapeake Bay. The ship put to sea on 21 September 1955 for nuclear attack drills along the United States East Coast; gunnery practice in operating areas out of Jacksonville, Florida, and assault beaching runs with men of the [[3rd Marine Regiment (United States)
 * 3rd Marine Regiment]] and their vehicles and combat equipment on the coast of North Carolina. Walworth County returned to Little Creek on 8 November 1955 and spent the following months in local waters with trips to Guantanamo Bay and the Caribbean.

First Mediterranean deployment 1956
Walworth County left Norfolk with a load of ammunition on 7 May 1956 and, two weeks later, arrived at the United States naval base at Port Lyautey, French Morocco. On 9 May 1956, she sailed for Greece and arrived at Piraeus on 30 May 1956 for operations with an amphibious task force of the United States Sixth Fleet which took her to principal ports of the Mediterranean Sea.

Second Mediterranean deployment 1958
Walworth County returned to Little Creek on 25 March 1958 but a month later headed for Morehead City, North Carolina. There, she loaded Marines and combat cargo in preparation for an amphibious training operation to be held in the Mediterranean with forces of the United Kingdom and Italy. She transited the Strait of Gibraltar on 14 May 1958 and visited the ports of Izmir, Turkey; Athens, Greece; and Suda Bay, Crete. However, the operation was cancelled because of Middle East tensions, and Walworth County had the distinction of acting as a primary control ship in the initial landing of Marines at Beirut, Lebanon, on 15 July 1958. Her operations in this area continued until 1 October 1958 when she departed Beirut and sailed for the United States. She reached Morehead City on 19 October 1958 and became a unit of Amphibious Squadron 6.

She returned to Little Creek on 4 May 1967 and spent a month undergoing maintenance and post-repair training.

Walworth County devoted September and October 1967 to a goodwill tour off Deal Island, Maryland, and Operation "JCOC 37," an amphibious assault off Onslow Beach, North Carolina. From 27 October 1967 to 10 November 1967, Walworth County was deployed to the Caribbean. On the ship's return to Little Creek, she began an overhaul and then prepared for an upcoming Mediterranean tour.

Seventh Mediterranean deployment 1967-1968
On 3 January 1968, Walworth County got underway for Morehead City, where she embarked Marines and loaded equipment. On 6 January 1968, she rendezvoused with five minesweepers and began the voyage across the North Atlantic for her seventh Mediterranean cruise.

Operations in U.S. waters 1968
After a month of maintenance, Walworth County participated in a riverine warfare exercise in Virginia's James River, which taught the fundamentals of river warfare and lessons learned in the Vietnam War, from 9 July 1968 to 19 July 1968. The ship then spent the remainder of July and most of August undergoing a tender availability.

Southern Command deployment 1968-1969
Walworth County got underway on 23 September 1968 for a United States Southern Command deployment as a member of Landing Ship Tank Division 41.

Operations in U.S. waters and the Caribbean 1969-1970
From 1 March 1969 to 16 May 1969, Walworth County underwent upkeep at the Norfolk Shipbuilding and Drydock Corporation in Berkley, Virginia. The ship then began a period of upkeep at her home port of Little Creek. On 21 July 1969, she started amphibious refresher training and then prepared for movement overseas. From 15 September 1969 through 25 November 1969, the ship operated in the Caribbean Ready Group.

Upon her return to Little Creek, Walworth County began another period of leave and upkeep. Then she conducted a training exercise from 12 January 1970 to 16 January 1970. On 30 January 1970, she began a month of tender availability by repair ship USS Vulcan (AR-5), which was moored at the Naval Station Norfolk. This work lasted until 20 February 1970, when Walworth County returned to Little Creek.

South America and Panama deployment 1970
Following several months of local operations, Walworth County sailed independently on 8 July 1970 for South America. Her mission was primarily one of good will. She delivered earthquake relief supplies to Peruvian ports and carried Project Handclasp material to Ecuador. For the remainder of the deployment, Walworth County carried out many and varied missions, ranging from being a home for Smithsonian Institution scientists performing marine biology research to acting as a ferryboat for United States exhibits to a regional fair at Bocas del Toro, Panama. The scientists worked with the Smithsonian Tropical Research Institute, which conducts research all around Panama including the Panama Canal, Bocas del Toro Archipelago, and Laguna de Chiriquí. During her three-month deployment, Walworth County steamed over 9,000 nautical miles (16,668 kilometers), and she received a letter of commendation from Admiral C. D. Nace, Commander, United States Naval Forces, Southern Command and Commandant, 15th Naval District. After a final transit of the Panama Canal, Walworth County headed homeward, arriving back at Little Creek on 23 October 1970.

Inactivation and decommissioning 1971
Following the post-deployment leave periods, Walworth County commenced preparations for inactivatipn. On 4 January 1971, operational and administrative control of the ship was shifted from Amphibious Force, United States Atlantic Fleet to the Inactive Ship Maintenance Facility, Norfolk, Virginia.

After three months of work by her crew, Walworth County was decommissioned on 2 April 1971. She subsequently was towed to Orange, Texas, where she arrived on 14 April 1971. She was drydocked on 11 May 1971 for the underwater phase of inactivation, with the topside phase scheduled to commence upon completion of the drydock phase. She then was laid up in the Atlantic Reserve Fleet, Texas Group at Orange, Texas.

Military Sealift Command service 1972-1973
In May 1972, Walworth County was scheduled for transfer to the Maritime Administration and layup in the National Defense Reserve Fleet at Suisun Bay, Benicia, California, but instead she served in a non-commissioned status with a primarily civilian crew as a cargo ship in the Military Sealift Command (MSC) as a United States Naval Ship, USNS Walworth County (T-LST-1164), from May 1972 until stricken from the Navy List on 1 November 1973.

Reserve status and transfer to Peru
On 19 June 1974, Walworth County was turned over to the Maritime Administration and berthed at Suisun Bay as part of the National Defense Reserve Fleet.

On 7 August 1984, Walworth County and three of her sister ships -- USS Traverse County (LST-1160), USS Waldo County (LST-1163), and USS Washoe County (LST-1165) -- were leased to Peru, and Walworth County was commissioned into service in the Peruvian Navy as Paita (DT-141) on 4 March 1985. Peru renewed the lease on all four ships in August 1989 and August 1994, and the United States sold all four outright to Peru on 26 April 1999 under the Security Assistance Program; all four were struck from the U.S. Naval Register on the day of the sale. She was decommissioned by the Peruvian Navy in September 2012.
