A campaign during this time frame (Cold War 70's) would be great. I'd love to play a campaign based on this era. Don't forget to include some Tango's, early Victor's, and Foxtrots along with the November and Swiftsures. Too bad SCX didn't include Seawolf (the old one
), Halibut, and Nautilus. Those legacy boats rock.
And yes, count me in as one of the interested parties in your campaign.
