When was the last time Royal embarked for a full deployment? It's not because we don't want them to, but because "main effort" drives the fact they physically can't do it beyond individual dets (CHF) or Coy's (RM).
I remember 1999 when quite a lot of CHF went to sea for a sustained period, and took part in a combination of exercises and operations. I would expect that type of deployment will happen again post-2015....
There have been a more than a few CHF types who've re-catted to grey lynx to get on in the promotion stakes, including a couple of bootnecks.
