The USS Chimo (ACM-1) was the lead vessel of her class of minelayers in the United States Navy during World War II. Originally built as the US Army Mine Planter USAMP Colonel Charles W. Bundy by Marietta Manufacturing Co. in Point Pleasant, West Virginia, she was converted at Norfolk Navy Yard before being acquired by the Navy on April 7, 1944. Commencing service immediately upon acquisition, she was commissioned the same day and assigned to the Atlantic Fleet. Constructed as a converted mine planter, the Chimo was fitted for naval operations, serving primarily as a minelayer and tender. Her notable wartime service began with her deployment from Norfolk on May 13, 1944, to support the Normandy invasion. She anchored off Utah Beach from June 7 to June 19, acting as the flagship of Commander Minesweepers West. During this period, she provided vital tender services to both British and U.S. minesweeping forces, ensuring the safe passage of supply ships by maintaining open lanes through minefields. Following the initial invasion period, Chimo operated along the French coast, including at Cherbourg, Saint-Brieuc Bay, and Brest, from June 20, 1944, until March 5, 1945. After returning to the United States for overhaul, she arrived in San Diego on July 3, 1945, for repairs and training. Her post-war service took her to the Pacific theater, where she operated off Eniwetok, Saipan, and Okinawa until early 1946. She then returned to Sasebo, Japan, before heading back to the United States via Saipan, Eniwetok, Pearl Harbor, and San Francisco, arriving on April 16, 1946. Decommissioned on May 21, 1946, Chimo was transferred to the War Shipping Administration and sold in 1948. She was later repurposed as the tuna seiner MV Day Island in 1963. Throughout her service, the USS Chimo earned two battle stars for her contributions during World War II, marking her as a significant vessel in naval mine warfare and amphibious support operations.
