Hey nsomnia,

Very sorry - just realised I never got around to sending you those links!

Most of the resources I've been gathering are only relevant to the interior of Project 641 submarines, but there are a few sites which might be useful to you:

• http://tvre.org/en/torpedo-fire-cont...german-u-boats - Detailed description of fire control systems on U-boats. Since many US and Soviet systems were directly or indirectly descended from the technology found in U-boats, this may be somewhat useful.
• http://www.gwpda.org/naval/w0100000.htm - brief description of torpedo firing proceedures.
• http://www.maritime.org/doc/oberon/index.htm - a collection of manuals from Canadian O-class (Oberon) submarines. One of the most detailed resources on a cold war era submarine I have found. Contains everything you would ever want to know about electrical & hydraulic systems, torpedo tubes, engines, etc, along with some more limited info on sonar and sensor systems.
• http://navyleague.org.au/wp-content/...Part1-1996.pdf - an Australian Navy magazine from 1996. The article "Foxtrot on Show" has some interesting info on old (and newer) Soviet submarines and tactics.
• http://belfercenter.ksg.harvard.edu/...rinesinCMC.pdf - article on the role of Soviet submarines in the Cuban Missile Crisis. Could be of use to you if you plan to cover that era of history.
• http://www.hnsa.org/resources/manuals-documents/ - Collection of documents from the Historical Naval Ships Association. Some useful content, including manuals for US fleet boats from WWII.
