Originally laid down as LST-902 by the Dravo Corporation of Pittsburgh, Pennsylvania on 5 November 1944; the ship was launched on 16 December 1944, sponsored by Mrs. Michael Grom; and commissioned at Algiers, Louisiana on 15 January 1945.

Steaming via Pearl Harbor and Midway, she reached Yokosuka, Japan, on 15 September and began supply runs in support of American naval and military operations in Korea.

Between 31 July and 25 August she carried elements of the 3rd Marine Division to Japan; and, after returning to San Diego on 2 October, underwent overhaul at Alameda the remainder of the year.

Named USS Luzerne County (LST-902) on 1 July, she underwent deactivation overhaul; and, after sailing to Astoria, Oregon, on 29 August, she decommissioned there on 30 November to rejoin the Pacific Reserve Fleet.

She joined the active list on 15 April and, following shakedown and type training out of San Diego, she departed for the east coast on 24 May and reached Little Creek, Virginia on 19 June.

After completing a run to Florida waters and back early in 1965, she joined naval forces operating to stabilize a crisis in the Dominican Republic.

During the remainder of the year she made numerous runs between the United States and the Dominican Republic, shuttling troops, support equipment, and military cargo from Southport, North Carolina, to Santo Domingo and to San Juan, Puerto Rico.

Departing Norfolk on 19 January 1966, she loaded an LCU at Charleston; transited the Panama Canal on 1 February; touched at Pearl Harbor and Subic Bay; and arrived Saigon on 21 April.

During the next two weeks she operated in the South China Sea and took part in freeing SS Excellency, an American merchant freighter, from a reef on Triton Island in the Paracels.

Although damaged during salvage operations, Luzerne County carried the merchantman's cargo of ammunition to Bangkok, Thailand, where she arrived on 16 May; thence, she steamed to Sasebo, Japan for repairs and overhaul.

Departing Sasebo on 2 July, Luzerne County resumed supply runs to South Vietnamese ports in support of the American war effort.

During July, August, and September she carried military stores from Okinawa to Nhà Bè, Vũng Tàu, and Nha Trang, and during the next two months she hauled cement from Kaohsiung, Taiwan to Phan Rang.

All four ships then began a six-week voyage from Da Nang to Guam, Pearl Harbor, San Diego and finally to the mothball fleet in Vallejo after which they were removed from active service.
