Service history

Destroyer tender, 1922–1924

Denebola served on the Atlantic Coast until 21 November 1922 when she cleared Philadelphia for the Mediterranean and duty as tender and repair ship to the U.S. Naval Detachment in Turkish waters. She got underway from Constantinople 18 November 1923 and called at Bizerte and Tunis, Tunisia; Gibraltar; and the Azores on her way to New York, where she arrived 23 December. Denebola joined in winter maneuvers in the Caribbean in 1924. She was placed out of commission in reserve at Philadelphia on 9 August.

In reserve, 1924–1940

Except for the period 1931 to 1934 when she served as barracks ship at Norfolk for the crews of battleships undergoing modernization, Denebola remained out of commission, at Philadelphia until she was towed to Baltimore, Maryland in 1940. She was commissioned in ordinary there 18 January 1940 for overhaul and refit.

Reactivated, 1940

Again in full commission, on 6 April 1940 Denebola sailed to Norfolk for shakedown exercises in Chesapeake Bay, then returned to Baltimore to have flag quarters installed. On 14 August she arrived at Norfolk Navy Yard and reported to Commander, Destroyers, Atlantic Squadron, U.S. Fleet, to overhaul destroyers and serve as flagship. On 1 September she sailed for Halifax, Nova Scotia, arriving five days later, to prepare and transfer to the British government destroyers involved in the land bases-destroyers exchange. She was visited by the Earl of Athlone, Governor General of Canada, on 8 September. Returning to Norfolk 3 November, she made two similar trips to Halifax in the next month and a half.

World War II

During early 1941 Denebola served at Norfolk, tending destroyers and conducting schools in repair work, cruising to Guantanamo Bay, Cuba, once and to Bermuda twice. She arrived in Casco Bay, Maine on 12 September to serve as tender to destroyers and other ships there until 5 July 1944.

Denebola sailed from Norfolk on 24 July 1944 for duty in the Mediterranean, furnishing tender services at Cagliari, Sardinia, during the invasion of southern France. She continued this duty at Ajaccio, Corsica, and St. Tropez, France, until 23 September when she put into Naples for tender duty until 27 October. She returned to Casco Bay, Maine 1 December. Arriving at Boston 30 April 1945 for repairs, Denebola got underway 13 May for the Pacific, arriving at Eniwetok 30 June. She provided upkeep and repair services to destroyers and other ships until 6 November when she sailed for San Diego, arriving 26 November. She aided in preparing ships for decommissioning until 14 February 1946 when she got underway for San Francisco. Denebola was decommissioned there 10 April 1946 and transferred to the Maritime Commission for disposal 1 July 1946.

Denebola received one battle star for World War II service.
