Blueprints & technical illustrations

[uss_sea_tiger]

As a draughtsman who started my working life before computers, I love looking at old blueprints, engineering drawings & technical illustrations. I'm looking for drawings of any description for old US navy boats from the S class to Tench class. Can any of you fine folks point me in the right direction?
Thanks

This site has general arrangement plans of quite a few US diesel boats:

A dozen different technical manuals from the late war/early post war period:

Here's a goldmine I just stumbled across; hundreds of Bureau of Ships drawings of the Balao-class USS Pampanito:
