It is a Soviet-origin Tango-class submarine. There is a large parking area, visitor center and shop near the floating sub as well. You can also see the eastern electric torpedo, as well as the medical room, the captain's room, and the officer's cabin. You can also spot dolls in Russian navy clothing placed in those rooms. However the experience of walking around the submarine is more exciting, don't miss it.
