USS Impeccable, an 890-ton Auk class minesweeper built at Alameda, California, was commissioned in April 1944. During the next year, she performed escort and patrol duties in the Pacific. In March-June 1945, Impeccable took part in the Okinawa campaign, enduring several Japanese air attacks while serving on minesweeping, patrol and rescue missions. With the coming of peace, she cleared mine fields in Japanese waters before returning to the United States in December 1945.

Out of commission from March 1947, Impeccable was placed back in active service in March 1952. She took part in Korean War mine clearance and patrol activities from September 1952 to March 1953. Impeccable spent the next two years operating along the U.S. Pacific coast and was reclassified MSF-320 in February 1955. She was decommissioned in October 1955 and remained in reserve until sold for scrapping in 1974.
