Aegis formations against mass missile attacks

How many navies have ships that could survive mass cruise-missile and anti-ship missile volleys?

The scale of the attack matters, but Aegis-equipped ships could have a chance, particularly when operating together in a formation.

The size of the incoming attack has to be defined before judging a ship's chances of surviving it. An Aegis-equipped ship is given a chance, especially when operating as part of a formation. The comparison also leaves room for simpler swing-arm launchers where the expected threat is less intense. No missile count or probability of survival is specified.
