US submarines can fire from refit docks if they had to ... the Russians report to have such a good range that the melting of the ice caps are revealing their hiding places via satellite (just guessing on that one).
Sure the Russians have the edge with range, but do they have ice cream, pop corn, Clint Eastwood, Star Trek, and "R" rated movies on board? Casino night, half way day, cable grams from home, Xbox 360 games make USN submarines a better place to live for (90) days.
Not to mention a supply corps that has and will continue to keep US Naval forces the leader in ship maintence no matter where they may hover.
Yes, folks the boomer I was on didn't steam we just hovered around the same area all day staying out of the shipping lanes.
