I have a buddy who joined the navy in the early 80’s. Before the Regan buildup took hold. Assigned to the Nimitz, elinsisted, worked on S-3s.
They had MAD - I remember him mentioning it.
He didn’t last more than two years. Old civilian habits had him fail a wiz quiz.
S3s were also used as tankers.
I hear they were using them as cods, too...
