The ballistic missile submarine crews from Kings Bay became far more distrustful of strangers after the USS Georgia was sunk. Their screening procedures became far more intensive, and they held themselves further apart from the other American military services. They overhauled their training systems and followed more vigorous policies when it came to removing people from the boats for what was once considered minor reasons. Anyone or anything could be a threat to them after all. So it was only prudent to remove as many threats as possible to reduce the chances of Bad Things happening. And they became even more determined to disappear into the oceans whenever they deployed. Decades of lax policies were trimmed and they became the wraiths of the oceans once more, keeping away from both their foes and their friends. Assuming they had any friends of course.
