A CVBG doesn't go into an area with known bad guys subs in a real war scenario. The hostile Sub would be tracked and probably sunk in transit long before it became a threat to the CVBG. A CVBG only goes into sanitized waters.

"Sanitized" waters aren't always sanitized. Of this, I can assure you.

Like I said unless the mission is worth the risk the CVBG doesn’t go. It is all risk assessment. If there was a hostile sub with no known position except somewhere in the Sargasso Sea, that is unacceptable. I cannot give you details because it is classified but the CVBG has a lot of people helping it locate subs that are not necessary part of the CVBG.
