I'm not sure, when I read about the DD-21(SC-21) it had some sort of huge gun capability, and this one, the DDG-1000 series was changed, it carries missiles, so that might have been one of the changes due to budget cuts. It was a while back when I read about the DD-21, but I will look for the source, it may have been taken down, seems like it was from one of the big defense contractors, had some great renderings and animations...
