You would have enjoyed the USS Hawkbill (637 Sturgeon class).
The classic Hawkbill story involved a crewmember running into an old bud from bootcamp and the bud gets invited aboard for a tour. In the story, the guy is fairly religious and shows up on the pier for his tour.
The first thing he notices is the ship's banner (SSN 666). He goes aboard for his tour and climbs down the ladder where he's taken to Control. He sees a large nameplate that says SINS (ship's inertial nav system) near another nameplate that says DEMON (demodulated sound display) and runs off the boat.
