It seems that no real classification scheme really holds true in any navy now-a-days.
What's also interesting is that the USNavy is still holding on to the "all in one" ship design philosophy, with every ship a total package capable of performing all functions. This has its advantages of course, but also has the disadvantage of every ship making every platform very very expensive and too costly to loose. It will be interesting to see how the LCS program integrates into such a traditional blue-water fleet and what capabilities will be deemed as necessary for the platform...
