In my own (limited) experience, I can't think of a single Peterhead, Broch, Irish Sea or Arbroath boat which doesn't use GPS as its primary navaid.
It's a bit like the passing of the sextant I think - nice to read about in a Hornblower novel, but an absolute arsehole to use from a pitching deck.

The point is that GPS can be knocked out or otherwise interfered with in times of war. If there is no back up nav aids, this puts operations at risk.
I don't think anyone is saying that GPS should not be a primary navaid, but some are saying that GPS should not be the exclusive navaid.
