Assigned to the Atlantic Fleet, Marlboro departed Boston 14 September for shakedown in Chesapeake Bay. On 15 October Marlboro got underway from Naval Operating Base, Norfolk, Virginia, for duty with the Service Force out of New York City. She served as a barracks ship along the East Coast to the end of the year. On 8 January 1946, she steamed for the Caribbean, arriving 5 days later at Guantanamo, Cuba, where she remained until sailing 15 May with U.S. Marines embarked for the East Coast. Marlboro reached Norfolk on the 20th.[1]
Eight days later, she moved on to Green Cove Springs, Florida, anchoring on 30 May. Assigned to the Atlantic Reserve Fleet on 1 June, she was decommissioned in January 1947 and was berthed on the St. Johns River.[2] Marlboro was struck from the Naval Register on 1 December 1963 and scrapped in 1965.[1]
