Being a former member in the Navy's Nuclear Sub Fleet (Fast Attack of course!) like many in our dept. at work,I found a worth of information on submarines which has been declassifed. Check it out www.americanhistory.si.edu/subs/ It even has THE former 'rack' of my fellow shipmate/now my Leadman. Check out the Mark 48 torpedo(55 knots),you remenber NICK, that's what I wanted you to name one of your kayaks(tandem) at ACSKS a few years ago. Will you be there this year? Wayne G.
