USS Marlin (SST-2)

The USS Marlin (SST-2) is a historic T-1-class submarine that served in the United States Navy from 1953 to 1973. Originally known as USS T-2, it was renamed Marlin in 1956 and was one of the smallest operational submarines in the U.S. Navy. After being commissioned in Groton, Connecticut, the vessel operated mainly out of Key West, Florida, and for more than a decade served as a target and training ship. In that role, it helped test and evaluate equipment and tactics for submarine and anti-submarine warfare. The Marlin also took part in various fleet exercises, including mine warfare drills in the 1960s. After it was decommissioned in 1973, the submarine was turned over to the Navy as a museum ship. Today it is on display at Freedom Park at the Greater Omaha Marina in Omaha, Nebraska, where it serves as a memorial and visitors can see this piece of maritime history up close.
