Wikki rocks ! it seems that this Sub is just waiting decommission. Read about the Virginia class, much more techie than the aging Angeles class subs. The whole battlefield command and enchilada into these puppies. And at over 1 billion a pop, how many you think we need?
In all honesty--
As many as we can get out hands on!
Joking aside, I'm not sure how many they plan to get.
