The USS Betelgeuse (AK-28/AKA-11) was an Arcturus-class attack cargo ship built for the United States Navy, distinguished as the first vessel named after the star Betelgeuse in the constellation Orion. Laid down as a C-2D cargo ship on 9 March 1939 by Sun Shipbuilding & Drydock Co. in Chester, Pennsylvania, she was launched as Mormaclark on 18 September 1939 and delivered to Moore McCormack Lines later that year. The Navy acquired her on 29 May 1941, renaming her Betelgeuse shortly thereafter, and commissioned her as AK-28 on 14 June 1941. She was later reclassified as an attack cargo ship (AKA-11) on 1 February 1943. Constructed with a hull suited for rapid cargo unloading, Betelgeuse was designed to support amphibious operations during World War II. She initially operated in the Atlantic, conducting maneuvers off North Carolina and Virginia, and transporting cargo to Bermuda and the West Indies. With the outbreak of war, she was deployed to the Pacific in early 1942, supporting Allied efforts in the Solomon Islands. She participated in the Guadalcanal campaign, arriving in August 1942, where she unloaded supplies under Japanese air attacks and claimed multiple enemy aircraft shot down, all while sustaining only minor damage. Betelgeuse also took part in the Mediterranean invasions, notably Sicily in July 1943 and southern France in August 1944, providing critical logistical support. Her service included a notable grounding incident during the Sicily campaign and repairs at various yards along the East Coast. She was instrumental during the Okinawa campaign, standing off Hagushi beaches on D-Day (April 1, 1945), where she endured kamikaze attacks that caused minor damage and injuries. After Japan's surrender, Betelgeuse supported occupation forces in Japan and China before returning to the U.S. She was decommissioned in March 1946 and later operated commercially under the name Mormaclark and Star Betelgeuse until her scrapping in 1972. Throughout her service, she earned six battle stars for her distinguished contributions to the war effort, marking her as a significant vessel in maritime wartime logistics and amphibious operations.
