As I mentioned awhile ago, (assuming SK wins) I think it might be a good idea to keep the first boat there and having training and support start there, it's likley the sub will be completed prior to the Esquimalt base being fully modified and equipped to deal with it. Perhaps when the 2nd boat is launched it stays there and works up and warranty issues dealt with as well. The first sub sails to the West coast. Possibly the 3 and 4th move to the East coast once facilities and shore crews are ready there.
I suspect that we may keep the Vics running till the 2nd boat is worked up. It will depend on operational demand, crew availability, shoreside space and money. Not to mention if you retire the Vics, where are you going to store them and with the incoming subs needing the docking space as well? I still think if we go KSS, the government will sell the Vics to a friendly nation. That gets rid of a problem quickly.
