"On display, according to Graduates source, was a secret anti-aircraft missile developed for the Seawolf class of attack submarines. The Navy planned to use the missile to defend the subs when sailing ahead of the fleet without air cover, especially in shallow water when vulnerable to shore-based defenses."

The multi-tube launcher swivels to point the missile in the desired direction before launch. Once out of the tube, the missile is no longer under control of the submarines weapons software.
As I understand it, this lack of control, especially in a highly trafficked area like the south shore of Long Island, necessitated a second sub with missile capacity to be used as a backstop.
So two questions I would ask, if I had any clue at all concerning the military and ASW, is how the submarine determines what direction to point the missile in and what use is a missile that cannot be controlled to the target? But since I obviously don't know what I'm talking about then there is no point in asking that.
