There's a sub-launched SAM called the IDAS
4 IDAS SAM can be fitted to a torpedo sized canister (like quad-packed ESSM) and the missile has 20 km range. It's designed for subs to defend itself against ASW aircraft and helicopters.
Going back to earlier posts in the thread, the idea of towing an underwater SAM launcher behind the ship is quite silly, unless if you're very certain that the enemy aircraft will only come from that direction.
For surface ships, having longer-range sensors and SAM is probably more important than towing an underwater SAM launcher.
As for the small deep submersibles, if there's any military value to them, it's probably not sticking MANPADS into the hull. Mini subs are more useful for surprise torpedo/mine attacks and special missions. Putting SAM's and CIWS guns on them is a waste of space.
As technology progress, I think we'll see underwater combat UAV's replacing the manned mini sub category. An UAV deployment ship could go to an operational area and unload a pack of combat UAV's underwear. The UAV's follow pre-programmed search and attack routes before returning. IFF probably won't work very well with ships, so anyone who wanders into the combat zone "box" will be sunk as collateral damage.
