If NATO don’t, I doubt if others do.
I'm not sure what point you are trying to make.
You say many NATO warships don't, which infers that some do. Which is quite understandable as it will depend on what they are up to at the time.
Then you extend that to speculate that other ships in general don't transmit! If you actually mean other countries warships don't, again, that's equally understandable but most of us don't sail in waters where non NATO ships operate. Also, NATO warships are a bit few and far between in Brittish waters these days, unless you happen to sail through a Wednesday War Day exercise area.
