Ebony sailed from San Francisco, California, 24 May 1942 for the South Pacific Ocean. After a brief period in the Fiji Islands, she arrived at Auckland, New Zealand, 27 July, to serve as net gate tender.
She sailed to Noumea in January 1943 to assist in towing a stranded vessel to safety and remained until May to salvage Shaw (DD-373). Ebony continued her net tending in the South Pacific, based primarily at Nouméa and Espiritu Santo, until the end of the war. During this time, she was reclassified AN-15 on 20 January 1944.
She returned to San Pedro, California, 8 October 1945, and was placed out of commission in reserve at Astoria, Oregon, 23 March 1946. She was struck from the Naval Vessel Register on 1 September 1962 and scrapped in 1976.
