Found this image in the BBS of Korea Defense Net.  Shows several of the latest or projected classes of ROK Navy ship.  The KDX-2 and KDX-1 have completed their builds, and are now being followed by the ROKN version of AEGIS in the KDX-III.  The first “PKX-A” commissioned as PKM-711 in early December 2008.  The first FFX is still to be built.

(Yeah, I know the pennant numbers on the ships are backwards…I just shamelessly copied the image and didn’t alter it.)
