The USCGC Klamath (WHEC-66) was an Owasco-class high endurance cutter built specifically for the United States Coast Guard during World War II. Constructed by Western Pipe & Steel at their San Pedro shipyard, the vessel was named after Klamath Lake in Oregon. Although intended for wartime service, the end of World War II meant that Klamath did not see combat during the conflict. She was commissioned on June 19, 1946, initially designated as WPG-66, a patrol gunboat, a designation later changed to WHEC-66 to reflect her role as a High Endurance Cutter. The "W" prefix indicates her status as a Coast Guard vessel. Klamath’s homeport was Seattle, Washington, where she served from her commissioning in 1946 until 1973. Her operational duties encompassed law enforcement, ocean station patrols, and search and rescue operations across the Pacific. She also participated annually in Bering Sea Patrol missions, highlighting her versatility and endurance in harsh maritime environments. Throughout her service, Klamath was involved in notable events including the inspection of the Soviet MV Olyturka in March 1966, which had sought refuge in U.S. waters after a casualty. Shortly thereafter, she detected and escorted out two Japanese fishing vessels, Bansho Maru No. 38 and Tenyo Maru No. 3, in U.S. waters. In January 1972, she assisted the Japanese freighter Tenzan Maru, which was taking on water 800 miles west of Seattle; the crew boarded the vessel, performed temporary repairs, and escorted her to San Francisco. During her deployment to Vietnam, from May 1969 to January 1970, Klamath served with Coast Guard Squadron Three, supporting operations during the Vietnam War. Decommissioned on May 1, 1973, Klamath was subsequently sold for scrap in November 1974. Her service record reflects her role as a versatile and resilient vessel contributing significantly to maritime law enforcement, rescue, and international operations during her active years.
