On 1 July 1955, she was redesignated Clearwater County (LST-602) after counties in Idaho and Minnesota.
The tank landing ship was operated by the Air Force from September 1957 to September 1969 when she was transferred to the temporary custody of the Maritime Administration. She was struck from the Navy list on 1 May 1972 and sold to Mexico on 30 May 1972 where she served as Manzanillo (IA-02).
