The Korean navy has shown some impressive growth in recent years. It has complete transformed itself from a coastal defense force into a blue-water navy.

The KDX-I, KDX-II, and now the KDX-III destroyers are all modern and very impressive. The new Dokdo LPH are aslo very impressive vessels.
Here's what they will have by 2010:
KDX-I DDG - 3
KDX-II DDG - 6
KDX-III DDG - 2
FFG-FFK - 9
Dokdo LPH - 2
All of this is very impressive, blue water material. A lot of it is based on modernizing their forces, but also in responding to the PLAN and the JMSDF. In that context, here's what a ROKN strike group might look like in the 20-teens:
The KDX-III is, simply put, the most powerful AEGIS vessel in terms of shear fire power anywhere, including the US vessels. Their will just neve be too many of them for South Korea. I have made recommendations that the US use the KDX-III design as a starting point for a bridge US AEGIS crusier until the CGX gets over its current difficulties, has the technology it wants to deploy avaialabnle, and begins being produced in some numbers.
Here's a link to a page regarding that proposal:
The overall modern designs of the South Korean navy are very efficient and very capable, and will add singificantly to the overal naval deterrent in the region for US allies in particular, even if the realtionship between South Korea dn Japan is strained from time to time.
In that regard, the Japanese, in the same time frame with over 50 modern destroyers, two helo-carriers and three smaller LPH type vessels (the Osumis) will maintain status as the major naval force in the region.
