I would say that I'm very comfortable with the capability that our submarines have in operating in the Arctic in the marginal ice zone, that is, in the vicinity of the ice edge—which is where all the activity is occurring, including activity on the surface—in terms of surveillance, in terms of understanding what is happening in the Arctic, and being prepared to respond across the spectrum of operations whatever the contingency might be.
I think the Victoria class submarine is a very capable submarine that is now on the edge of achieving full operational capability. As these submarines work through their operating cycles, we are going to see them generating real effect—as they have already, but in a more persistent way—here at home, in the Arctic, and overseas.
