The USS Silversides, a submarine from World War II known for sinking at least 23 enemy vessels, has been relocated from Muskegon, Michigan, to Sturgeon Bay, Wisconsin, marking its first dry dock repair in over half a century. Towed by the tugboats Nickelena and Erika Kobasic, this 312-foot submarine is undergoing a $3.5 million restoration, supported by private contributions and a grant from the National Park Service. The restoration work, which includes sandblasting, painting, and structural repairs, is being carried out by Fincantieri Bay Shipbuilding. Commissioned on December 15, 1941, the USS Silversides completed 14 war patrols and earned 12 battle stars. The project is anticipated to finish by October, after which it will return to Muskegon for public tours.
