The USS Xanthus (AR-19) was a Xanthus-class repair ship constructed during World War II, designed to provide essential repair services to the fleet. Laid down on June 6, 1944, at the Bethlehem-Fairfield Shipyard in Baltimore, Maryland, she was initially intended for the Royal Navy under the name HMS Hecla (F 175). Launched on July 31, 1944, and sponsored by Mrs. J.W.A. Waller, she was delivered to the U.S. Navy on loan on August 16, 1944. The ship was renamed Xanthus and commissioned on May 9, 1945, with the designation AR-19. Constructed as a relatively large auxiliary repair vessel, the USS Xanthus was equipped to perform maintenance and logistical support for the fleet. After commissioning, she underwent training and transited through the Panama Canal to reach Pearl Harbor on July 20, 1945, where she served as a repair ship. In August, she sailed to Adak, Alaska, to support operations for the planned assaults on the Kurils and northern Japan. However, following Japan's surrender, her role shifted to support and occupation duties. As part of Task Group 40.2, she arrived at Ominato, Japan, on September 9, 1945—the same day Japanese forces there surrendered. She served as the flagship for the commander of Task Group 56.2, a repair and logistics group, until November 21, 1945. Subsequently, Xanthus operated out of Okinawa as part of Service Squadron 104 through January 1946. In February, she was dispatched to Qingdao, China, where she supported American naval efforts amid the turbulent post-war situation until April 8, 1946. Following her service in Asia, Xanthus returned to Norfolk, Virginia, and was laid up at the Maritime Commission facility in the James River in an "on hand" status, remaining inactive until 1961. She was officially struck from the Navy List on September 1, 1962, and sold for scrapping in Cleveland, Ohio, in 1974. Throughout her brief but notable service, USS Xanthus played a vital logistical role in supporting American naval operations during the immediate post-World War II period.
