As background on the namesake, USS Tranquillity was converted into a hospital ship and commissioned in April 1945, with a bed capacity of 802 and a complement of 568. USS Tranquillity began service as a base hospital at Ulithi and was dispatched in August 1945 to the Palau Island to receive the survivors from the USS Indianapolis and transport them to Guam. She was then assigned to assist the 3rd Fleet by returning 766 patients from Guam to the US. In September 1945, she was assigned to Operation Magic Carpet to return troops from overseas to the US and was designated APH-114. In March 1946, USS Tranquillity was decommissioned. She was struck from the Naval Register in September 1961. Tranquillity received one battle star from World War II service.
