OK in the first place we are not talking about boomers (missile boats) we are talking about Virginia-class submarines or fast attack boats. These are the ones that that hunt down other subs and or try to take on an enemy surface fleet. They seldom use a periscope using instead both active and passive sonar and listening devices to set up and launch attacks with. The closer they are to the surface the easier they are to find. When it gets to the point that they have to use a periscope things are pretty bad. So I really doubt some seaman is operating the scope. both out attack subs and our boomers are supposed to carry out their respective missions without ever coming close to periscope depth unless they are launching SEALS for a mission. And they still do that while being submerged. They may do a shore reccon with the periscope but there is going to be an officer on that scope, not some seaman. Our Navy in WWII developed a torpedo that could be fired from 300 feet IIRC without ever raising the scope. The weapon was designed to home in on the noises made by a ships propeller. That torpedo was also used by hunter killer groups going after the German Uboats. Things have greatly advanced sense then. Us and the Russians and maybe the Chinese have all experimented with nuclear depth charges. Who knows what we have of don't have. So yea, almost every piece of military electronic equipment is hardened against EMP. What happens if the boat is in port tied up to a dock if hit with EMP? All contingencies have to be factored in.
Look, the JG talking about this makes it fishy. Something like that and most things involving US subs is/are classified. They don't talk about on board systems. Heck the US Navy won't even tell you how fast that sub is nor how deep it will operate. Sure they give you numbers but so does the Air Force. Most often the AF gives data that isn't correct too. So now all of a sudden a JG and Senior Chief have loose lips?

Today's Featured Article - A Cautionary Tale - by Ian Minshull. In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
