Not surprising nor news. Russian/Soviet subs also had this. But it really is a last ditch weapon, not really something to be deployed as a first defense against aerial ASW assets.
How about using IRST to detect the plane.
What about develope a combo of SAM+torpedo, launch like a torpedo and it moves away from the sub, and as it surface it blast up like a missile. So this way, enemies can't detect where the missile is actually launched therefore can't track the sub.
ICBM can launch under water, VLS SAM should able to do the same /w some modifications. If they somehow perfect the SAM like I mentioned torpedo+SAM, then all P-3 plane and ASW helicopters would be finished.

btw I also like to point if implmenting a remote controll surfaced mini-sub that has the radar and IR seeker that help to guide the bigger sub.
