The USS Keokuk (AN-5/CM-8/CMc-6/AKN-4) was a versatile mine and net laying ship built in 1914 by William Cramp & Sons in Philadelphia. Originally launched as the SS Henry M. Flagler, she was renamed SS Columbia Heights in 1940 before being acquired by the U.S. Navy in July 1941. She was subsequently converted for naval service, initially classified as a net layer (CMc-6), then reclassified as a motor minesweeper (CM-8), and later as a net cargo ship (AKN-4). The ship measured approximately 194 meters in length with a displacement suited for her role in mine and net laying operations, though exact dimensions are not specified on the source page. She was commissioned in February 1942 and served primarily along the Atlantic and Pacific theaters during World War II. Keokuk’s operational history began with her deployment along the U.S. East Coast, operating out of Norfolk and Key West. She was reclassified as a minelayer and took part in high-priority mine-laying along the Atlantic coast, including a notable deployment to North Africa, where she laid mines off Casablanca in late 1942. After returning to the U.S. for repairs, she participated in the Mediterranean campaign, operating out of Oran, Algeria, and Gela, Sicily. During the Sicilian campaign, she was attacked by six enemy aircraft but successfully defended herself with anti-aircraft fire. In late 1943, Keokuk was transferred to the Pacific, where she supported key amphibious assaults, including at Saipan, Peleliu, and Iwo Jima. At Iwo Jima, she played a crucial role in net laying during the invasion, despite sustaining damage from a Japanese aircraft attack that resulted in 17 killed and 44 wounded. She continued operations at Okinawa, laying antisubmarine nets until the battle concluded. After the war, Keokuk returned to the U.S., was decommissioned in December 1945, and sold in 1947. She earned five battle stars for her wartime service, marking her as a significant vessel in the Navy’s mine and net laying operations during World War II.
