Soviet submarine C-189 (S-189) is a floating museum. Built at St. Petersburg's Baltic Factory and launched in 1954, the C-189 is a 613-class diesel-electric submarine that saw 35 years service in the Soviet fleet. Decommissioned in 1990, the C-189 eventually sank in the harbour at Kronshtadt, but was rescued in 2005 by a local businessman and former submariner, who decided to turn the vessel into a museum.
