Ah, okay.
Well, I'd say two things. One is just to return to the blackout nodes. The places where we're not blacked out is where people are, so I wouldn't want to leave you with the perception that we have blackout nodes right over top of where our citizens are. That's not the case. It's the unpopulated, vast spaces where we're prepared to accept a degree of blackout noding, which our safety and security interests there may be able to anticipate.
That said, the subsurface is a highly compartmentalized discussion, and we have great confidence that we're sharing what we have with our own subsurface fleet, which has been deployed in operations recently to include a joint inter-agency task force south, in the Pacific waters around Central America, just before Christmas. That submarine put us into an operating environment which required full exposure of the subsurface picture that we understand.
