Госпитальное судно USS Tranquillity (AH-14)

USS Tranquillity (AH-14) was a Haven-class hospital ship that served in the United States Navy during World War II.

Originally built as Marine Dolphin in 1943 by Sun Shipbuilding & Drydock Co. under a Maritime Commission contract, she was renamed Tranquillity on June 22, 1944; launched on July 25, 1944; and sponsored by Miss Carol P. Meekins. The Navy acquired her from the Maritime Commission on August 14, 1944, and she was converted into a hospital ship in New York City by Atlantic Basin Iron Works. She was commissioned on April 24, 1945.

With a capacity of 802 beds and a crew of 568, Tranquillity was among the first six fully air-conditioned ships in the Navy. It featured 2,400 cubic meters of medical storage and a 100-bed field hospital.

Tranquillity began her service as a base hospital at Ulithi and was dispatched on August 3, 1945, to the Palau Islands to pick up survivors from the USS Indianapolis (CA-35) and transport them to Guam. She was then tasked with supporting the 3rd Fleet by returning 766 patients from Guam to the U.S. On September 26, 1945, she was assigned to Operation Magic Carpet to repatriate troops from overseas to the U.S. and was designated APH-114.

On March 25, 1946, Tranquillity was re-designated AH-14 and was decommissioned and placed in reserve on July 16, 1956. She was removed from the Naval Register on September 1, 1961.

On July 15, 1974, Tranquillity was sold for scrapping to Northern Metal Co., a division of North James River Associates, for $58,300. She was withdrawn from the Suisun Bay Reserve Fleet and delivered to Northern Metals on August 5, 1974.
