>>I understand the secrecy around the reactor, but why classify everything else back there?
Its easier to keep track of that way. Some things can point to classified information. Example: sea water pump discharge pressure gauge could indicate operating depth. So they classify everything, just in case.
Didn’t think of that. :)
As a surface sonar tech, I was invited to ride the Finback for a week in 1970. They let me go sit on the stack and go active until we left Chesapeake Bay. “One ping only” NOT.
