The USS Delphinus (AF-24) was originally built in 1915 as the SS San Mateo by Workman Clark and Co., Ltd., in Belfast, Northern Ireland. As a cargo vessel, she was designed to transport provisions, specifically chilled and frozen goods. The ship was acquired by the U.S. Navy on August 11, 1942, and was commissioned on the same day under her original name. Shortly thereafter, on August 22, 1942, she was renamed USS Delphinus. During World War II, USS Delphinus served primarily in the South Pacific theater. She departed San Francisco, California, on September 12, 1942, and arrived in Auckland, New Zealand, on October 4 of the same year. From her base in Auckland, she operated throughout the region until the end of 1945. Her primary mission was to carry chilled and frozen provisions to forward bases across the South Pacific, including the Society Islands, Fiji, and the Samoan Islands. This logistical support was crucial in maintaining the operational readiness of Allied forces in the Pacific theater. In January 1946, USS Delphinus called at Manila before returning to the U.S. West Coast, arriving in San Francisco on February 23, 1946. After a brief period of cargo operations along the West Coast and to Pearl Harbor, she was transferred to New Orleans, Louisiana. The vessel was decommissioned on May 8, 1946, and the same day, was delivered to the War Shipping Administration, marking the end of her military service. USS Delphinus's role as a cargo ship was vital in supporting Allied operations across the Pacific during World War II, exemplifying the logistical backbone that sustained military campaigns far from home ports. Her service highlights the importance of fleet auxiliaries in wartime maritime logistics.
