World War II, 1945–1946

After shakedown off the coast of Florida, LST-839 loaded Army troops and cargo and departed New Orleans for the Pacific on 9 January 1945. Steaming via the Panama Canal, Pearl Harbor, and Eniwetok, she reached Saipan on 10 March. There she prepared to support the invasion of Okinawa; and, after embarking Seabees and loading construction equipment, she sailed on 12 April for that strategic island, which lay at the gateway to the heart of the Japanese Empire. The campaign was well underway when LST-839 reached Kinmu Wan, Okinawa on 17 April. Despite heavy enemy air raids, she debarked troops and discharged cargo, then returned to Saipan on 21 April to transport additional troops. During the four remaining months of the war, she shuttled troops and equipment among the Marianas, Philippine, and Okinawa staging areas for the possible invasion of Japan. The enemy's acceptance of Allied peace terms precluded an invasion, and the landing ship then operated between the Philippines and Japan, transporting occupation forces until mid-November.

Arriving at Guam on 12 November, LST-839 embarked 500 veterans of the Pacific fighting and sailed on 17 November for the United States. Steaming via Pearl Harbor, she reached San Francisco on 28 December. She sailed for Astoria, Oregon on 25 January 1946; decommissioned at Vancouver, Washington on 24 July; and entered the Pacific Reserve Fleet. While berthed in the Columbia River, she was named USS Iredell County (LST-892) on 1 July 1955.

Vietnam War, 1966–1970

Iredell County recommissioned at San Diego, California on 18 June 1966. Completing training, Iredell County sailed to join the 7th Fleet on 3 September 1966. En route to Japan with her first cargo since 1945, she called at Pearl Harbor and her new homeport of Guam. Exchanging cargo at Iwakuni, Japan on 12 October, Iredell County departed for Da Nang, Vietnam, arriving on 21 October. She shuttled petroleum, building materials, rations, troops, and equipment between Da Nang and Chu Lai 65 miles to the south. She also shuttled cargo from Danang to Cửa Việt Base for most of 1967. In 1968, after an overhaul on Guam and refresher training in Yokosuka, Japan, she sailed for the Vietnam rivers. She carried ammunition and other cargo to the base at Binh Thuy (about 50 mi. from the sea on the Bassac River) and others farther upstream until March 1969 when she returned to Guam for a month. In April 1969, she once again returned to Da Nang, via Subic Bay in the Philippines, and continued shuttling materials to Cửa Việt Base, Tan My, and Chu Lai. In the summer of 1969 she took the first of President Nixon's 25,000 marines and their equipment from Vietnam to Okinawa. Iredell County transported more than 7,360 tons of cargo and made 12 landings.

Transfer to Indonesia

She continued to serve the Pacific Fleet and participate operations underway in Southeast Asia until July 1970 when she was decommissioned and transferred (loaned) under terms of the Security Assistance Program to Indonesia. Renamed Teluk Bone, the ship was struck from the Naval Vessel Register and sold outright to Indonesia in February 1979 and still active in service with Indonesian Navy as of December 2018.^[1] The ship took part in landing operations during the Indonesian invasion of East Timor, such as during the Battle of Dili.^[2] KRI Teluk Bone (511) together with another World War II-era LST, KRI Teluk Ratai (509) finally decommissioned from Indonesian Navy service at the Second Fleet HQ (Koarmada II), Surabaya on 15 August 2019.^[3]

On 15 September 2012, Teluk Bone and another World War II-era LST KRI Teluk Ratai (509) (ex-USS Presque Isle (APB-44)) participated in the commemorative sail Morotai in order to commemorated the Allied landing operation in Morotai on 15 September 1944. Both ships participated in the original landing on 15 September 1944 as a part of the Allied expeditionary force.^[4]
