USS Windsor, a 13,143-ton attack transport, was built at Sparrows Point, Maryland. Originally begun as the merchant freighter Excelsior, she was taken over by the Navy while under construction and launched under the hull number AP-100, which was changed to APA-55 by the time she was commissioned in June 1943. After shakedown, the ship went to the Pacific, where she took part in the Marshalls operation in January-February 1944. During the rest of the year she participated in landings on the northern shore of New Guinea in April and May, at Guam in July, Peleliu in September and Leyte in October.

Windsor was overhauled on the U.S. west coast during late 1944 and early 1945. For the rest of World War II, she transported men and materiel between the United States and the central and western Pacific. After the fighting ended in August, she supported the occupation of Japan and took part in Operation "Magic Carpet", the effort to bring U.S. service personnel home from the former war zone. This duty was completed by early January 1946, and Windsor was sent to the east coast where she decommissioned in March. She was turned over to the War Shipping Administration in August 1946 and subsequently had a long career as a merchantman under the names Paul Revere (from 1947) and Expeditor (from 1949). She was scrapped in Taiwan in 1972.
