The USS Marion County (LST-975) was an LST-542-class tank landing ship built for the U.S. Navy during World War II. Constructed at Bethlehem-Hingham Shipyard in Hingham, Massachusetts, she was laid down on December 1, 1944, launched on January 6, 1945, and commissioned shortly thereafter on February 3, 1945. As a typical vessel of her class, she was initially unnamed, identified solely by her hull number, but later uniquely bore the name Marion County, after counties in seventeen U.S. states, becoming the only U.S. Naval vessel to do so. Following her shakedown in Chesapeake Bay, LST-975 departed New York on March 27, 1945, heading to the Pacific via the Panama Canal. She participated in amphibious exercises at Pearl Harbor and subsequently embarked troops and equipment in Seattle, departing for Okinawa in late June 1945. She arrived just after the Japanese surrender, on August 17, 1945, and was involved in post-war operations including transporting troops and equipment for the occupation of Japan, notably reaching Nagasaki and later supporting operations in the Philippines. After World War II, she was decommissioned on April 16, 1946, and transferred to the Army for operations in the Far East. Recommissioned in 1950 at Yokosuka, Japan, she played a significant role in the Korean War, arriving at Inchon in September 1950, where she was engaged in supply and logistical support amid active combat, including being harassed by sniper fire and mortar shelling. She continued supporting UN forces through late 1951, resupplying at Wonsan and supporting armistice efforts. Throughout her service, LST-975 earned six battle stars for her Korean War service. She was renamed Marion County on July 1, 1955, and participated in training exercises, including a simulated assault on Iwo Jima in 1954. She was decommissioned in 1956, placed in reserve, and transferred to the Military Sea Transportation Service, operating mainly in the Pacific. In 1962, she was transferred to South Vietnam as RVNS Cam Ranh (HQ-500), later serving in the Philippine Navy as BRP Zamboanga del Sur (LT-86). She was decommissioned by 2014, marking a lengthy and diverse maritime career spanning World War II, Korea, and Southeast Asia.
