During World War II, LST-786 was assigned to the Asiatic-Pacific theater and participated in the assault and occupation of Iwo Jima from 12 to 28 February 1945, and the assault and occupation of Okinawa Gunto in May and June 1945. Following the war, she performed occupation duty in the Far East and saw service in China until mid-December 1945. LST-786 was decommissioned on 9 July 1946 at Astoria, Oregon and assigned to the Columbia River Group of the Pacific Reserve Fleet. On 1 July 1955 the ship was redesignated USS Garrett County (LST-786).
Recommissioned on 15 October 1966 at Mare Island Naval Shipyard. Garrett County saw extensive service during the Vietnam War, operating as part of Operation Game Warden, a brown-water navy effort to keep the rivers free of Viet Cong infiltration. Four LSTs were recommissioned to support river patrol operations with the intent of keeping three ships on-station at any one time supporting a River Division of 10 Patrol Boat, River, a Detachment of 2 UH-1 Helicopter Gunships of HC-1, later HAL-3 Seawolves and a SEAL Platoon. The ship not on-station was undergoing ship repairs in the Western Pacific. Garrett County reported on-station to CTF 116 on 12 March 1967 and operated as a Patrol Craft Tender (AGP) for the next 48 months on the rivers of the Mekong Delta.[1]
The ship participated in the following campaigns: Vietnamese Counteroffensive - Phase III (29 November 1967 to 29 January 1968); Tet Counteroffensive (30 January to 1 April 1968); Vietnamese Counteroffensive - Phase IV (2 April to 30 June 1968); Vietnamese Counteroffensive - Phase V (1 July to 1 November 1968); Vietnamese Counteroffensive - Phase VI (2 November to 2 December 1968 and 23 January 1969); Tet/69 Counteroffensive (28 February to 8 June 1969); Vietnam Summer-Fall 1969 (9 June to 11 August 1969, 7 September 1969, and 31 December 1969 to 21 February 1970); and Vietnamese Counteroffensive - Phase VII (1 September 1970, 5 to 30 November 1970, and 31 December 1970 to 2 February 1971).
LST-786 earned one battle star for World War II service, and two Presidential Unit Citation, two Navy Unit Commendation, and eight battle stars for the Vietnam War.
Decommissioned and transferred to South Vietnam for service in the Republic of Vietnam Navy on 23 April 1971, she was renamed RVNS Can Tho (HQ-801). The ship and her crew escaped to the Philippines during the fall of the South Vietnamese government, after which custody was transferred to the Republic of the Philippines. She was renamed BRP Kalinga Apayao (LT-516) for service in the Philippine Navy.
She was decommissioned in September 2010 and was reportedly scrapped at Naval Base Cavite in 2012.
