No this is from the old WW 2 subs. this is how they all looked back then . what they called the pig boats. You are talking about the nuclear subs they have now. I have also been on them, but like you say they are all classified. when I was in the Navy I held a top secret classification.
was it on the new boats ( nuclear ones ) ? I never did serve on one, but have done maintenance on them . They are sure a lot different than the old one's,alot more room. after that I went into the torpedo engineer tech service . the rest of my time was on shore duty,no more sea duty.
