The USS Oneota (YN-110/AN-85) was a Cohoes-class net laying ship built to protect U.S. Navy ships and harbors during World War II through the deployment of anti-submarine nets. Constructed by the Marine Iron and Shipbuilding Co. in Duluth, Minnesota, she was laid down on February 9, 1944. The vessel was initially designated YN-110 but was renamed Oneota on February 26, 1944, before being launched on May 27, 1944, with Mrs. Peter S. Rudie serving as her sponsor. She was officially commissioned on March 12, 1945. The ship's early operational history saw her leaving Lake Superior on April 10, 1945, heading towards the Atlantic via the St. Lawrence River. By early May, she was in Boston, Massachusetts, remaining in southern New England waters for about a month before heading west to the Pacific theater. From July 25, 1945, to January 21, 1946, Oneota operated along the U.S. West Coast, primarily from the Naval Net Depot in Tiburon, California. She then arrived at Pearl Harbor in late January 1946 for a two-month stay. Oneota’s notable service included her participation in the atomic testing at Bikini Atoll. In March 1946, she was assigned to Joint Task Unit 1.2.7, a salvage group for Operation Crossroads. She traveled to Bikini Atoll on March 22 and helped prepare the waters for the atomic tests Able and Baker conducted in July. During this period, she planted moorings and assisted in arranging target vessels for the tests. After the successful atomic tests in July, she engaged in salvage operations before departing for Kwajalein and Guam in August. She subsequently operated between Guam and Rota until mid-October, then returned to the United States, visiting Pearl Harbor and San Francisco. Decommissioned on February 6, 1947, at San Diego, she was part of the Pacific Reserve Fleet and later transferred to the U.S. Maritime Administration's National Defense Reserve Fleet at Suisun Bay in 1962. Her ultimate fate remains unknown, and she was struck from the Navy List at an unspecified date. The USS Oneota’s service reflects her role in both wartime harbor defense and the post-war atomic testing efforts, marking her as a vessel of maritime and military significance during her era.
