The USS Tranquillity (AH-14) was a Haven-class hospital ship built during World War II, originally launched as Marine Dolphin in 1943 by Sun Shipbuilding & Drydock Co. under a Maritime Commission contract. She was renamed Tranquillity on June 22, 1944, and launched on July 25, 1944, with Miss Carol P. Meekins serving as her sponsor. The vessel was acquired by the U.S. Navy from the Maritime Commission on August 14, 1944, and underwent conversion into a hospital ship at New York City by the Atlantic Basin Iron Works. She was officially commissioned on April 24, 1945. Designed to serve as a fully equipped hospital vessel, Tranquillity featured a bed capacity of 802 and a medical staff of 568 personnel. She was among the first six U.S. Navy ships to be fully air-conditioned, enhancing the comfort of both patients and crew. The ship boasted an extensive medical storage capacity of 85,000 cubic feet and was equipped with a 100-bed field hospital, enabling her to provide comprehensive medical care in wartime conditions. Tranquillity's service began shortly after her commissioning, departing Hampton Roads on May 5, 1945, for shakedown trials and assignment to the Pacific Fleet. She served as a base hospital at Ulithi and was dispatched on August 3, 1945, to the Palau Islands to receive survivors from the USS Indianapolis (CA-35) and transport them to Guam. Subsequently, she assisted the 3rd Fleet by returning 766 patients from Guam to the United States. On September 26, 1945, she was assigned to Operation Magic Carpet to repatriate troops, and her designation was changed to APH-114. On March 25, 1946, she was redesignated AH-14 and remained in active service until she was decommissioned and placed in reserve on July 16, 1956. She was struck from the Naval Register on September 1, 1961. The USS Tranquillity was sold for scrapping in 1974 to Northern Metal Co. for $58,300, marking the end of her maritime service. During her operational history, she earned one battle star for her service in World War II, exemplifying her role in providing vital medical support during the war.
