The ship I most associate my Dad with while he served in the Navy during his regular tour was the submarine USS SENNETT (SS 408), which he was about in the late 1960s. Perhaps 1966-1970. During that time I think he served an navigation, engineering, and executive officer. Herewith a few pictures at the end of her operational life, most likely shots off South America and the Antarctic. These are all likely official U. S. Navy photographs (though not marked), so I will give them credit.
