The USS Cygnus (AF-23) was a Cygnus-class cargo ship constructed in 1925 by Cammell Laird in Birkenhead, England. Originally named SS La Perla, the vessel was acquired by the U.S. Navy on August 12, 1942, and commissioned the following day. As a cargo vessel, she was tasked with delivering vital supplies and equipment to various locations in the Pacific Theater during World War II. During her service, USS Cygnus primarily operated in the South Pacific, starting with convoy voyages to Pearl Harbor. In late 1942, she departed San Francisco and arrived in Auckland, New Zealand, establishing a routine route that lasted until early 1944. Her missions involved transporting chilled meats and vegetables from Auckland to American bases across the Pacific, including Tongatapu in Tonga, Pago Pago in American Samoa, Bora Bora in the Society Islands, the Cook Islands, and Funafuti in the Ellice Islands. From January 1944 to September 1945, she continued similar logistical duties between New Zealand ports—Auckland and Napier—and key locations such as Espiritu Santo, Efate, Nouméa, and other strategic islands in the Solomon Islands and New Caledonia. Following the end of hostilities, Cygnus underwent an overhaul on the U.S. West Coast before proceeding to Okinawa in December 1945 to discharge cargo. She later operated out of Manus in the Admiralty Islands, supplying American and Allied bases until March 1946, when she returned to the United States. Arriving in New York in July 1946, USS Cygnus was decommissioned on July 18 of that year and transferred to the War Shipping Administration for disposal. Throughout her service, USS Cygnus played a crucial logistical role in supporting Allied operations across the Pacific, exemplifying the vital contribution of cargo ships to wartime supply chains.
