The submarine world is a small world indeed. I visited the USS Tennessee two years ago in Kings Bay, GA. I might know a few members of the crew.
When I was in, one of my jobs was to make sure the "presentation silver" was inventoried and appraised yearly. Submarines treat these gifts of silver received during commissioning almost as a baptism certificate, and I am sure that your dad's work has been treated with the same reverence.
You'd be surprise the artistry you can find onboard a nuclear power submarine.
To sort of get back on topic, let me say that we have nice sound systems too (indoor and outdoor ).
