On 27 December 1965, the ship commenced refresher training which continued into 1966.
The ship departed Yokosuka loaded with pontoon barge sections destined for Danang, South Vietnam. Following a short stop in Okinawa, the ship arrived at Danang on 22 February 1966. She then proceeded to Chu Lai and discharged the remainder of the cargo.
After hauling cargo to Danang, Chu Lai, Camranh Bay, and Phan Rang, Washoe County joined with an amphibious ready group whose mission was to conduct an amphibious raid, Operation Jackstay against Viet Cong southeast of Saigon. She served in a pioneering role as an advance base providing gunfire support, arms, ammunition, rations, and water to assault boat groups.
Washoe County returned to Yokosuka on 28 May 1966 for a brief period of repairs and rehabilitation. On 18 June 1966, the ship sailed for Okinawa to reload supplies, then made a visit to Hong Kong before resuming her duties as a cargo carrier along the Vietnamese coast.
In mid-August, she steamed through the Inland Sea of Japan and Shimonoseki Strait on her way to Korea. After a week of training with the Republic of Korea Navy, Washoe County returned to Iwakuni, Japan, and embarked Marines and cargo. Before returning to Yokosuka at the end of October 1966, the ship made two more lifts to Vietnam, carrying cargo to Chu Lai and Qui Nhon and returning equipment from Danang to Naha, Okinawa.
The year 1967 began with Washoe County in the port of Naha, Okinawa, loading cargo. She spent the month of January engaged in shuttle runs carrying cargo and personnel along the South Vietnamese coast and Okinawa and then enjoyed a rest and recreation visit to Hong Kong. The ship spent most of February 1967 conducting intracoastal logistic support lifts along the South Vietnam coast. On 20 February 1967, Washoe County participated in Operation De Soto, in which material was offloaded by Marine helicopters operating off the ship's main deck. The operation was concluded on 8 March 1967, and the tank landing ship underwent an upkeep period lasting from 20 March 1967 to 11 April 1967.
From 15 April 1967 to 2 June 1967, Washoe County made shuttle runs with cargo and troops to Chi Lung, Taiwan; Danang and Chu Lai, South Vietnam; Naha, Okinawa; Yokosuka, Japan; and Inchon, South Korea.

Washoe County retired to Subic Bay on 5 December 1967 and soon sailed to Okinawa for training exercises with Marines. She returned to Yokosuka on 18 December 1967 for upkeep which lasted into 1968.
On 1 March 1968, Washoe County sailed for Danang, South Vietnam, in company with USS Terrell County (LST-1157) and USS Westchester County (LST-1167), carrying causeway sections to be used at Wunder Beach, South Vietnam. The sections were splashed and moved into place on 17 March 1968. While engaged in the causeway installation, Washoe Countys port shaft was damaged; and she underwent repairs at Subic Bay from 21 March 1968 to 25 March 1968. She then returned to Vietnam, but further problems with the port shaft developed, necessitating more extensive repairs at Subic Bay which lasted until 29 April 1968. The ship then successfully completed sea trials and got underway for Japan and arrived at Yokosuka on 5 May 1968.
Washoe County underwent upkeep at Yokosuka which was not finished until early June 1968. On 3 June 1968, she began loading Marine equipment at Naha, and she delivered it at Subic Bay on 8 June 1968.

En route on 20 June 1968, Washoe County embarked two injured personnel from the American freighter SS John C. after that ship had run aground on the north reef of the Paracel Islands.
The next day, Washoe County returned to Danang and resumed duties with the amphibious ready group. With the exception of upkeep from 10 July 1968 to 20 July 1968, the ship served in the combat zone continuously through July and much of August. On 24 August 1968, Washoe County headed for her home port and arrived at Yokosuka on 12 September 1968.
Washoe County began her last deployment of 1968 off the coast of South Vietnam at the Ca Mau Peninsula for Operation Market Time, sealing off the coastline of South Vietnam and adjacent waterways from communist infiltration. From 27 October 1968 to 9 December 1968, she functioned as an emergency helicopter landing pad in evacuating eight U.S. Navy and United States Coast Guard personnel wounded in action and the body of one Coast Guardsman who had been killed in action ashore. She also dispensed fuel, food, water, and ammunition to 134 patrol boats and fired 42 naval gunfire support missions.
Washoe County arrived back at Yokosuka on 19 December 1968 and spent the end of 1968 there.
Washoe County began 1969 preparing for the cyclical yard overhaul period which commenced on 19 January 1969 and continued through 10 April 1969. From 20 April 1969 to 6 June 1969, she conducted refresher training and amphibious refresher training. On 12 June 1969, Washoe County got underway for the first deployment of the year as a support ship for Operation Seafloat/Tran Hung Dao III in the Ca Mau Peninsula of South Vietnam. Seafloat was a floating advanced tactical support base primarily for psychological warfare missions conducted in the Cua Lon River at the southernmost tip of South Vietnam. During this period, Washoe County served as a helicopter platform and provided logistics and communications support.
On 10 August 1969, after 46 days on station, Washoe County sailed via Subic Bay to Hong Kong for a two-week assignment as station ship. She got underway on 4 September 1969 for Yokosuka but was diverted by a trip from Okinawa to Danang and finally arrived at her home port on 23 September 1969. She remained there until 9 October 1969 when she transported a detachment of Marines and equipment from Okinawa to Numazu, Japan.
Departing Japan on 28 October 1969, Washoe County participated in Operation Keystone Cardinal, a major troop redeployment lift from Vietnam. During November, Washoe County steamed more than 7,000 nautical miles (12,964 kilometers) bringing troops and equipment from Vietnam to Okinawa before returning to Yokosuka on 3 December 1969 for annual inspections and the Christmas holiday season.
Washoe County took station as a Seafloat support vessel from 20 January 1970 to 12 March 1970 and again from 17 May 1970 to 2 August 1970. Between these two deployments, Washoe County served as station ship in Hong Kong from 18 March 1970 to 27 March 1970.
On 12 August 1970, Washoe County arrived at Osaka, Japan, to enjoy four days at the World's Fair, Expo 70. From 19 August 1970 to 19 September 1970, she underwent upkeep at Yokosuka and then made a visit to Hong Kong.
After stopping at Chu Lai, Vietnam, and Subic Bay, the Philippines, to load cargo on board, Washoe County headed for the California coast, via Pearl Harbor, arriving at San Diego on 10 November 1970. She offloaded Marine cargo at Camp Pendleton on 13 November 1970, then made a port visit to San Francisco.
Washoe County earned a Presidential Unit Citation, a Navy Unit Commendation, a Meritorious Unit Commendation, and twelve campaign stars for Vietnam War service. The campaign stars were for:
On 24 November 1970, Washoe County arrived at Bremerton, Washington, and, on 25 November 1970, her status changed to "in commission, in reserve." On 25 March 1971, the ship was decommissioned.
Washoe County was reactivated in January 1973 to serve as a cargo ship in a non-commissioned status with a civil service crew with the Military Sealift Command in January 1973, being designated the United States Naval Ship USNS Washoe County (T-LST-1165). This service continued until she was stricken from the Navy List on 1 November 1973. At that time, she was transferred to the Maritime Administration for layup in the National Defense Reserve Fleet at Suisun Bay, Benicia, California. The Washoe County was converted to civilian manning at Todd Shipyard in Long Beach, California during the summer of 1972 and was manned on 12 October by her civil service crew.
On 7 August 1984, Washoe County and three of her sister ships -- USS Traverse County (LST-1160), USS Waldo County (LST-1163), and USS Walworth County (LST-1164)—were leased to Peru, and Washoe County was commissioned into service in the Peruvian Navy as BAP Callao (DT-143) on 4 March 1985. Peru renewed the lease on all four ships in August 1989 and August 1994,[1] and the United States sold all four outright to Peru under the Security Assistance Program on 26 April 1999; all four were struck from the U.S. Naval Register on the day of the sale.
A section of interstate 80 at the state line of California and Nevada/Washoe County celebrates the crew of the USS Washoe County, the sign is located beneath the "WELCOME TO NEVADA" sign.
