The USS Sumter (APA-52) was a Sumter-class attack transport constructed during World War II, designed to support amphibious operations. Originally laid down as Iberville on 3 April 1942 by Gulf Shipbuilding in Chickasaw, Alabama, she was launched on 4 October 1942 and acquired by the Navy on 30 April 1943. After conversion into an attack transport by the Maryland Drydock Company, she was commissioned on 1 September 1943. The vessel measured approximately 455 feet in length, with a beam of around 62 feet, and was equipped to carry a complement of landing craft, troops, and supplies essential for amphibious assaults. She was outfitted with a considerable number of landing craft—31 in total—and a Beach Party unit, to facilitate beach landings during combat operations. USS Sumter's service record was marked by participation in major Pacific theater campaigns. She supported the Marshall Islands invasion in January 1944, landing battalion landing teams on Ennumennet and Ennubirr atolls. She also took part in the Saipan and Tinian landings in June 1944, where she delivered troops and supplies under heavy enemy fire, and provided casualty evacuations. Later, she participated in the Palau Islands campaign, landing troops on Angaur and Peleliu, and served in the Philippines, including the Lingayen Gulf invasion in January 1945. During the Okinawa campaign, she arrived off Yontan Airfield on 1 April 1945, landing over 1,350 marines, and remained off the beaches until sailing for the United States. Following hostilities, USS Sumter supported occupation duties in Japan, transporting Army troops and veterans. She earned six battle stars for her wartime service. Decommissioned on 19 March 1946, she was later sold into commercial service and converted into the SS Gateway City, the first container ship, in 1957. She was scrapped in Hong Kong in October 1978, marking the end of her maritime career.
