USS Clearwater County (LST-602), originally USS LST-602, was a United States Navy LST-542-class tank landing ship built during World War II and in commission from 1944 to 1946 and from 1950 to ca. 1957. Named after Clearwater County, Idaho, and Clearwater County, Minnesota, she was the only U.S. Navy vessel to bear the name. It was transferred to, and is currently in use by the Mexican Navy.

Service history

During World War II, LST-602 was assigned to the European Theater of Operations and participated in Operation Dragoon, the invasion of southern France, in August and September 1944. In 1946 she was decommissioned/

When the Korean war broke out, LST-602 was recommissioned in 1950 and performed service in the Korean Theater from 26 November 1951 to 25 July 1952 and from 19 July 1953 to 26 February 1954. She participated in the following Korean War campaigns:

On 1 July 1955, LST-602 was renamed USS Clearwater County (LST-602). She remained in U.S. Navy service until 1957.
