There were always certain unambiguous signs that the Soviets would have given a few days prior to initiating hostilities (WW3). One of them would have been to sortie vast portion their submarine fleet so that they would not be bombed while laying dockside. This is one reason that naval maneuvers were always announced and watched by all navies.
I expect that our aircraft carriers will depart the area until such time as their subs, with their limited endurance, return to base to get plastered by the USAF. Then the carriers will return in a big way. Until that time the USN will keep the carriers at a distance, providing air cover for the surface combatant vessels patrolling the strait. I also expect that our SSN’s will pick off a few using methods not discussed in public forums such as this.
It's no secret. Everyone knows you convince the captain to defect then fake a nuclear accident to get the crew off.
