The USS LST-850 was an LST-542-class tank landing ship constructed for the United States Navy during World War II. Built by the Chicago Bridge & Iron Company in Seneca, Illinois, she was laid down on August 15, 1944, launched on November 3, 1944, and commissioned at New Orleans, Louisiana, on November 27, 1944. The vessel measured typical dimensions for her class, designed for amphibious operations, with a focus on transporting troops, vehicles, and cargo directly onto hostile shores. Following her shakedown off Florida, LST-850 loaded military cargo at Gulfport, Mississippi, and departed for the Pacific Theater on December 31, 1944, transiting via the Panama Canal and San Diego to reach Pearl Harbor by February 1, 1945. She then participated in the final stages of the Pacific campaign, arriving at Guadalcanal in March and subsequently transporting LVTs and troops to strategic locations such as Eniwetok, Guam, Saipan, and Okinawa. During the Okinawa campaign, from late April to May 1945, she supported amphibious assaults by disembarking troops and cargo amid enemy air attacks. After the Okinawa operations, LST-850 helped transport Marine Division personnel and cargo to Saipan and Okinawa, participating in further amphibious actions against Iheya Shima and Aguni Shima in June 1945. As Japan neared surrender, she played a role in transporting occupation forces, sailing via Leyte to Manila Bay, then to Yokohama and Tokyo Bay, supporting occupation landings along the Japanese coast. Post-war, she returned to the United States, arriving in Astoria, Oregon, in December 1945. She served in the Pacific Reserve Fleet until she was placed in reserve on May 17, 1946, transferred to Portland in October, and decommissioned on January 18, 1947. The vessel was named USS Juniata County on July 1, 1955, becoming the only ship to bear this name, but was recommended for target destruction in 1958, and her name was struck from the Naval Vessel Register later that year. Her service highlights her role in pivotal Pacific amphibious operations during World War II and subsequent occupation duties.
