USS Manayunk (AN-81)

USS Manayunk (YN-100/AN-81) was a Cohoes-class net laying ship which was assigned to protect United States Navy ships and harbors during World War II with her anti-submarine nets. Her World War II career was short lived as the war was ending, and she was placed in reserve and eventually struck by the Navy.
