The USS Denebola (AD-12) was an Altair-class destroyer tender constructed originally as the SS Edgewood in 1919 by Skinner and Eddy in Seattle, Washington. She was transferred from the Shipping Board to the Navy on November 4, 1921, and underwent conversion at the Philadelphia Navy Yard before being commissioned as USS Denebola (AD-12) on November 28, 1921. The vessel featured a design suitable for supporting and repairing destroyers, serving as a mobile repair and maintenance platform. Initially serving along the Atlantic Coast, Denebola's early service included a deployment to the Mediterranean in late 1922, where she supported the U.S. Naval Detachment in Turkish waters. Her Mediterranean duties included stops at Constantinople, Bizerte, Tunis, Gibraltar, and the Azores, before returning to New York in December 1923. Throughout the 1920s, she participated in winter maneuvers in the Caribbean. The ship was placed out of commission in reserve at Philadelphia on August 9, 1924, but was later repurposed as a barracks ship at Norfolk from 1931 to 1934 during modernization efforts. She remained out of commission until 1940, when she was towed to Baltimore for overhaul and refitting. Recommissioned in April 1940, Denebola served as a flagship and tender for destroyers, conducting repair services and training. She played a role in the destroyers’ land-based training exchange with the British government, including visits to Halifax, Nova Scotia. Her duties extended to tending destroyers and conducting repair schools along the U.S. East Coast, with cruises to Guantanamo Bay and Bermuda. In 1944, Denebola was deployed to the Mediterranean, supporting operations during the invasion of southern France by providing tender services at Cagliari, Ajaccio, and St. Tropez, and later at Naples. After returning to the U.S., she moved to the Pacific in mid-1945, arriving at Eniwetok to continue repair services until November. She returned to San Francisco in 1946, was decommissioned on April 10, 1946, and transferred to the Maritime Commission for disposal. Denebola earned one battle star for her service during World War II, marking her as a significant support vessel in U.S. naval operations during the war.
