The USS Marengo (AK-194) was an Alamosa-class cargo ship constructed by Walter Butler Shipbuilders Inc. in Superior, Wisconsin, with her keel laid on July 4, 1944. Launched on December 4, 1944, she was sponsored by Mrs. R. W. Higgins. The vessel was acquired by the U.S. Navy at New Orleans, Louisiana, on August 24, 1945, and placed in service immediately, primarily used for ferrying operations between Beaumont and Galveston, Texas. Her commissioning occurred on September 21, 1945, but her service was brief; she was placed out of service upon arrival at Galveston on August 29 and was decommissioned on November 23 of the same year. Following her decommissioning, she was transferred to the War Shipping Administration and operated by the North Atlantic & Gulf Steamship Co., under the name Coastal Spartan. She served in this capacity until being laid up in the Wilmington, North Carolina reserve fleet in April 1948. The vessel remained in reserve until she was sold to Boston Metals Company in 1965 for non-transportation use. In December 1971, the ship was sold to Storm Drilling Company and converted into a drilling ship, renamed Cyclone. She underwent further conversion in 1975 to become a crane ship, receiving the name Ocean Cyclone. Later, in 1989, she was converted into a fish processing vessel by the Eastern Shipbuilding Company in Panama City, Florida. Since 2018, she has been permanently moored at Dutch Harbor, Alaska, functioning as a fish factory. She was acquired by Icicle Seafoods, Inc., in 1999 and subsequently bought by Westward Seafoods Inc. in 2022. Her maritime significance lies in her versatile after-service life, transitioning from a World War II cargo ship to a specialized fish processing vessel, reflecting the adaptability and enduring utility of her hull through decades of service.
