The USS Dionysus (AR-21) was a Xanthus-class repair ship that served in the United States Navy from 1945 to 1955. Originally launched as the Liberty ship SS Faithful by Bethlehem-Fairfield Shipyard on October 10, 1944, she was sponsored by Mrs. H. C. McClelland. The Navy acquired her shortly thereafter on October 25, 1944, and she was officially commissioned as USS Dionysus on April 28, 1945. Constructed as a conversion from a Liberty ship, the vessel was designed for repair and support duties, contributing to fleet maintenance during her active service. Her initial deployment began in mid-1945, with arrival at Pearl Harbor on June 30. Subsequently, she traveled to Eniwetok, where she served as a repair ship from July 24 to September 8, 1945. Dionysus then entered Tokyo Bay on September 17, 1945, providing repair services there until November 10, before moving for overhaul at Bremerton, Washington, arriving on November 28. Following her overhaul, she was stationed at San Pedro and was placed out of commission in reserve on January 31, 1947. She was recommissioned on February 13, 1952, and joined the Atlantic Fleet, arriving at Naval Station Norfolk on April 29. Throughout her service from this base, she primarily supported fleet operations along the U.S. East Coast, with a notable deployment to the Caribbean in 1953 to assist ships at Roosevelt Roads Naval Station, Puerto Rico. She returned to Newport, Rhode Island, in May 1954, continuing repair duties until early 1955. Dionysus was decommissioned again at Beaumont, Texas, on April 20, 1955, and was placed in reserve. She remained inactive until she was withdrawn from the James River Reserve Fleet on May 31, 1978. Subsequently, she was designated for use in an artificial reef program in North Carolina, marking the end of her maritime service.
