I recall this incident vaguely. Our mission is maritime warning, so it is largely an intelligence mission. There's quite a bit of analysis in order for us to declare something in our maritime lines of communication to be a matter for an advisory or warning. Whether those ships met that criteria or not, I don't recall.
When we talk under NORAD about the maritime domain, those would be the types of discussions I imagine we would have in due course, and this is what the commanders are doing. There is continuous concern, and continuous monitoring of what's happening outside. When we detect something that is not working well, we fix it.
That's the only thing I can offer to your question.
