73k	Starboard side view of the Cero (SSG-225), taken at Belle Isle in Detroit, where she was a training vessel, circa early- to mid-60s. She had been reclassed SSG before that. When she was a training boat, she never left the dock; she was re-fitted with some kind of weatherized structure just aft of the sail (which you can see in the photo), she got all of her power from land lines, and I think that most of what the crews did aboard her then were simulated dives, simulated torpedo firings, etc.	US Navy photo, courtesy of ussubvetsofworldwarii.org Text info courtesy of Tom Horn (son of Clarence Durwood "Durwood" Horn, 1925-1961).
