ASMs would not be very useful. First submarines have piss poor detection capability outside of their sonar which severely limits the range at which they could launch them. Then they already have torpedoes which are effective against ships and can be guided from the range at which a submarine would be likely to want to fire.

SAMs have been considered mostly to fight against their natural enemy: the helicopters but I don’t think it has ever been actually fielded.

The issue remains the same in both case. Submarines are slow and firing is loud and basically broadcast your position to everyone.
