18 of 28: The USS Hoga, center with white wheelhouse, a 100-foot-long Navy yard tugboat which is the last surviving Navy vessel from the 1941 attack on Pearl Harbor, sits in the mothball fleet in San Francisco Bay, Calif., in this Dec. 17, 1999 photo. Built in 1940, the tug is considered inactive by the Navy, which wants to scrap it. While there is interest in saving it, there are no firm offers. (AP Photo/ ERIC RISBERG)
