The USS Miantonomah (CM-10/CMc-5) was a coastal minelayer built on a commercial design by Pusey & Jones Corporation in Wilmington, Delaware. Originally launched as the SS Quaker in 1938, she was a fast inland water passenger and freight vessel, measuring approximately 280 feet in length with a beam of 48.7 feet and a depth of 13.5 feet. Her gross tonnage was 3,056 GRT, and she had a cargo capacity of 190,500 cubic feet. The vessel was powered by a General Electric cross-compound turbine driven by two Babcock & Wilcox boilers, developing 4,000 horsepower and capable of reaching speeds up to 17 knots. Acquired by the U.S. Navy in May 1941, she was converted into a coastal minelayer by Bethlehem Shipbuilding and commissioned in November 1941. Renamed USS Miantonomah, she served primarily along the East Coast, Africa, and the Mediterranean during World War II. Her early operational duties included laying minefields off Cape Hatteras, Key West, and in the Caribbean to combat German submarines. Notably, she participated in the North African invasion in November 1942, laying defensive mines near Fedala and Casablanca, and survived attacks by German U-boats U-173 and U-130 during this campaign. After repairs in Norfolk and subsequent minesweeping operations in the Caribbean, Miantonomah supported the Allied invasion of Europe, arriving in England in May 1944. She operated out of Bristol and Plymouth, providing escort and dispatch duties before supporting port clearance and salvage operations following the liberation of French ports. She served as flagship for Commander Task Force 125 during operations in Cherbourg. Tragically, on September 25, 1944, while leaving Le Havre, Miantonomah struck a mine and sank rapidly, resulting in the loss of approximately 58 crew members. Her final moments were marked by a heroic effort to save the vessel, with damage control efforts proving unsuccessful. For her service, USS Miantonomah received two battle stars. Her maritime significance lies in her contributions to mine-laying operations, her role in supporting the North African and European campaigns, and her ultimate sacrifice in the Atlantic theater of WWII.
