During the Yom Kippur War in 1974, we had three carriers in the Med.
ASW was turned over to the air assets and our own attack subs. The junior officers didn't know that over a dozen attack subs surged into the Med, and at least two were under the carrier groups every day.
Drove us nuts, while the staff officers laughed at our reactions.
Sounds like not much has changed.
