This is a test of a nuclear-armed ASROC missile, no doubt overkill for diesel submarines, though more advanced nuclear submarines would be a prime target for such a system. How far out would a submarine have to be from the blast to survive? If it is really so effective, this is the answer to anti submarine countermeasures? Forgetting the potential environmental impact, this is more useful than even advanced torpedoes or aerial ASW. One whisper from an enemy submarine and an otherwise unremarkable destroyer can potentially fuck a variety of tasty targets, especially nuclear powered ones.

ASW aircraft with nuclear depth charges could allow a country without a potent navy to absolutely fuck up any enemy navy with prejudice, especially their submarine forces. With nuclear warhead armed AShMs even carrier groups could be under credible threat (If the enemy doesnt intercept the missile that is). If one was to use such a weapon, it would probably have an escort along with some 'bait' aircraft to give the nuke-armed aircraft a greater fighting chance.
