Going back to the article.
It ignores the fact that the Type 23s are still probably the quietest ASW ships afloat and that the Astutes are probably on a par with the best USN nuclear subs. Possibly most importantly it ignores the Amphibious assets.
During most of the Cold War the RN was a ASW and mine-warfare biased force and was world class at it. BUT it wasn't an all-round force.
NOW, it seems to be being heavily biased towards Amphibious operations and littoral support. Hopefully it will be world class at that, but again it will not be an all-round force.
The criticism is ill-informed and really is a way of saying that the UK can't afford to be world-class at everything.
