Well...many US submarines receive antifouling in the yards - I suspect for aesthetic reasons during launching ceremonies!
This turns to an unsightly green during patrols and wears away.
New silicon based fouling release paints work on different principles - the poor marine creatures can't get a grip!
So constant motion is actually an advantage for this type of paint. Of course last I heard it only being applied to Arleigh Burkes and Ticonderogas, but marine fouling is a larger problem for submarines than commonly suspected!
Good for sonar?
But this is straying off topic.
Short answer - some US submarines will have antifouling paint, some will not. It will depend on the individual boat and time period!
