Hey, don't mean to try to hi-jack your thread or anything but, if you'd like I think there's more than a few parts of the OAS (Omitted American Submarines) mod which could fit in pretty well with the 62 era. Specifically the GUPPYs and other 'Fleet Boat' mods which were still in service, as well as other boats like the Nautilus, Skate and Tang class which were around since the 50s.
Some of this stuff would probably require some adjustment (some sensors and weapons which were out of service by 68 or not yet in service by 62) but other than that could probably work quite well. Please contact me if you have any interest.
