The USS Alcyone (AKA-7) was an Arcturus-class attack cargo ship constructed during the late 1930s and early 1940s, primarily serving during World War II. Originally laid down as Mormacgull under a Maritime Commission contract (MC hull 30) on January 12, 1939, at the Sun Shipbuilding & Drydock Co. in Chester, Pennsylvania, the vessel was launched on August 28, 1939. She was delivered to Moore-McCormack Lines, Inc., on October 13, 1939. The U.S. Navy purchased her on May 31, 1941, and she was renamed Alcyone, designated AK-24, and commissioned on June 15, 1941, under Commander Daniel M. McGurl. Initially serving as a cargo ship, Alcyone was engaged in Atlantic operations, including voyages to Iceland, the Caribbean, and evacuations of civilians, with her service marked by her resilience during a German submarine attack. She was later assigned to the Naval Transportation Service and participated in troop and equipment landings in the Pacific, including Guadalcanal, Makin Island, Kwajalein, and the Philippine Islands. Her conversion to an attack cargo ship was completed in November 1942 at Mare Island Navy Yard, where she received additional booms, a boat repair shop, and extra berthing. Alcyone’s service included participation in key amphibious assaults, notably the Sicily invasion in July 1943, and multiple operations across the Pacific theater such as the Gilbert Islands, Marshall Islands, and the Philippines. She faced enemy air attacks and rough seas but successfully delivered troops and cargo in critical campaigns. Her operational history extended into post-war support, including replenishing occupation forces in Japan and supporting the occupation of Tokyo Bay. Decommissioned on July 23, 1946, at Norfolk, Virginia, USS Alcyone was transferred to the War Shipping Administration and later sold to the Johnson Line in 1947, becoming the merchant vessel Star Alcyone. She was eventually scrapped in 1969. Her service record underscores her role in pivotal amphibious operations and logistical support during World War II, marking her as a significant vessel in U.S. naval maritime history.
