Originally laid down as USS LST-901 on 29 October 1944 by the Dravo Corporation of Pittsburgh, Pennsylvania; the ship was launched on 9 December 1944, sponsored by Mrs. S. A. Evans; and commissioned on 11 January 1945.

Recommissioned on 30 November 1951, LST-901 prepared for service in the Korean War, sailing from San Diego on 7 July 1952 for Hawaii, Midway, and Inchon, arriving on 5 September.

Logistic support lifts, amphibious landing rehearsals, and service as helicopter pad and control vessel for the Wonsan naval blockade were her missions until returning to San Diego on 21 May.

Between 29 August and 7 November she made seven trips to Hai Phong, North Vietnam to transport troops and refugees to Da Nang and Saigon in the South.

As the Vietnam War escalated, demands on American seapower again greatly increased, and early in 1966 Litchfield County was towed to Portland, Oregon for reactivation.

Sold for scrapping by the Defense Reutilization and Marketing Service (DRMS) on 1 January 1977, she was acquired by the Aphrodite Shipping & Trading Corporation S.A., of Panama and renamed Petrola 132.
