The USS Albireo (AK-90) was a Crater-class cargo ship constructed during World War II, originally laid down as the liberty ship SS John G. Nicolay. Built by Permanente Metals Corporation in Richmond, California, she was launched on 25 February 1943 and acquired by the U.S. Navy under a bareboat charter on 9 March 1943. After conversion for naval service by the Matson Navigation Co., she was renamed Albireo and commissioned at San Francisco on 29 March 1943. Her specifications include a length typical of Crater-class cargo ships, designed primarily for transporting supplies and personnel. The vessel was assigned to the Naval Transport Service, conducting various cargo runs along the U.S. West Coast, including deliveries to Seattle, Eureka, San Francisco, and Astoria. She undertook her first major deployment in April 1943, heading to the Pacific Theater, with voyages to Pearl Harbor, Espiritu Santo, Guadalcanal, Milne Bay, and Manus Island. These missions involved cargo and personnel transportation, supporting Allied operations across the Pacific islands. Throughout her service, Albireo frequently shifted ports, unloading cargo and equipment vital to ongoing military campaigns. Notable operations included delivering elements of Navy construction battalions and supporting occupation forces in Japan after the war’s end. She participated in multiple convoy missions, often pausing for repairs and alterations in San Francisco and Pearl Harbor. Following the war, she supported occupation efforts in Japan until late March 1946, after which she returned to the United States. She was decommissioned in Norfolk, Virginia, on 5 July 1946, and entered the National Defense Reserve Fleet. Subsequently, she was sold multiple times, serving under different names and flags, including SS President Steyn, SS Hidalgo, and SS Ocean Sailor, before finally being scrapped in Japan in 1967. The USS Albireo’s service exemplifies the critical logistical support provided by cargo ships during World War II, facilitating Allied operations across the Pacific and supporting post-war occupation and rebuilding efforts.
