My first thought while reading the article:

From 2016. This Drone Can Launch From Underwater, Soar Through the Air Dubbed CRACUNS, the prototype an remain at and then launch from several hundred feet underwater.

I'm sure the Chinese & Russians have something similar. Add warhead small warhead targeting phased array antennae - or area denial agent, i.e. NBC - and voila: Warship neutralized.

If they start destroying surface ships than the submarine launched strategic weapons start becoming more of a realistic option.
