Now, to help with research, here's a whole truck load of info on the old Fleet Boats, out there. (I, also, posted this on the Hyperscale board)
1) Floating Drydock, for plans, and "Fleet Submarines of WWII, a pictorial Histories Publication".
2) Leeward Publications, "Ship's Data (USS Bowfin (SS-287)".
3) An old one (if you can find it) is "Profile Warships #34 - USS Barb (SS-220)".
4) Squadron Shop's "US Subs in action".
5) The Sub Committee is a group of sub enthusiasts. <<http://www.subcommittee.com/>>;
6) USSVI (the Sub Vets) <<http://www.ussvi.org/>>; Find a local chapter (Base) and go to their next meeting. Some of the guys have been on the boats since the late 30s.
Lastly, there are, I believe, several submariners on this forum, including myself.
Now. What is it you want to know? If I don't know, I'll probably be able to tell you where to go for it. (No double entendre intended)
As far as the SSN goes, the Sub Committee and the Sub Vets can be a treasure drove of info, for the nukes, too. And, I believe, Floating Drydock may have plans.
