Are you talking about P-3s?

Nope. The S-3 Viking is a four-seater, twin-turbofan sub hunter that operated out of carriers. They've been retired, but the planes are mostly in flyable storage and could be reactivated again on short notice.

P-3s are fixed-wing, land-based sub hunters (though I thought these were being retired and replaced with a newer model.)

S-3s are folding-wing, carrier-based ASW aircraft.
