I can tell you one thing with certainty. People do NOT know what advanced weapons systems the US military has or how far along they are in development.
But there are plenty of publications out and about that write like they know what’s what.
When reading military matters, I always have in the back of my mind a guide that I will not know what is what unless I have a need-to-know and even then I may have only a limited compartmentalized view.
it’s not that I think we couldn’t or haven’t developed it.
it’s more that we really don’t need it we have warships and aircraft and even personal with anti aircraft capabilities already and stationed worldwide.
a sub being able to shoot down an aircraft near it is practical
a sub needing a missile to shoot down an aircraft halfway around the world is impractical especially when you can more easily use a different asset in already place
