The SS Fort St. Joseph was a cargo ship built in 1943, primarily used during World War II. It was part of the Fort class of vessels, designed to transport goods and supplies to support military operations. The ship was constructed in Montreal, Canada, and played a crucial role in the logistics of the war effort. After the war, the SS Fort St. Joseph was repurposed for commercial use, continuing to transport cargo across the Great Lakes. It was eventually retired from service and scrapped in the late 20th century, marking the end of its operational life.
